Fan Energy Savings Decisions
Axial fans are used for thousands of industrial applications consuming millions of kilowatts daily. The decision that saves dollars is to either automatically change fan speed or change blade pitch to save up to 50 percent of consumed power over a fixed pitch, constant speed fan. A discussion of the merits of each type is presented with actual test results.

Save Energy with Axial Fans
There are several ways to save energy in wet cooling towers and air cooled heat exchangers using axial fans. This paper will discuss ways to improve fan system efficiency in wet and dry towers both during the design phase and after installation by specifying energy efficient equipment. Variable pitch fan versus fixed pitch fan operation is discussed in terms of energy savings and means of control. The areas of interest to wet cooling tower users would be the influence on fan diameter and operating point on horsepower, how and when are velocity recovery stacks effective, the effect of varying fan speed to improve efficiency, and tip clearance effects. The areas of interest to dry tower (air cooled heat exchanger) users would be the effect of inlet losses, approach velocity losses, and losses due to air recirculation.

A utility framework for bounded-loss market makers
We introduce a class of utility-based market makers that always accept orders at their risk-neutral prices. We derive necessary and sufficient conditions for such market makers to have bounded loss. We prove that hyperbolic absolute risk aversion utility market makers are equivalent to weighted pseudospherical scoring rule market makers. In particular, Hanson�s logarithmic scoring rule market maker corresponds to a negative exponential utility market maker in our framework. We describe a third equivalent formulation based on maintaining a cost function that seems most natural for implementation purposes, and we illustrate how to translate among the three equivalent formulations. We examine the tradeoff between the market�s liquidity and the market maker�s worst-case loss. For a fixed bound on worst-case loss, some market makers exhibit greater liquidity near uniform prices and some exhibit greater liquidity near extreme prices, but no market maker can exhibit uniformly greater liquidity in all regimes. For a fixed minimum liquidity level, we give the lower bound of market maker�s worst-case loss under some regularity conditions. 1

Maker Can Construct a Sparse Graph on a Small Board
We study Maker/Breaker games on the edges of sparse graphs. Maker and Breaker take turns in claiming previously unclaimed edges of a given graph H. Maker aims to occupy a given target graph G and Breaker tries to prevent Maker from achieving his goal. We define a function f and show that for every d-regular graph G on n vertices there is a graph H with at most f(d)n edges such that Maker can occupy a copy of G in the game on H.

Hitting time results for Maker-Breaker games
We study Maker-Breaker games played on the edge set of a random graph. Specifically, we analyze the moment a typical random graph process first becomes a Maker�s win in a game in which Maker�s goal is to build a graph which admits some monotone increasing property P. We focus on three natural target properties for Maker�s graph, namely being k-vertex-connected, admitting a perfect matching, and being Hamiltonian. We prove the following optimal hitting time results: with high probability Maker wins the k-vertex connectivity game exactly at the time the random graph process first reaches minimum degree 2k; with high probability Maker wins the perfect matching game exactly at the time the random graph process first reaches minimum degree 2; with high probability Maker wins the Hamiltonicity game exactly at the time the random graph process first reaches minimum degree 4. The latter two statements settle conjectures of Stojakovi? and Szab�. We also prove generalizations of the latter two results; these generalizations partially strengthen some known results in the theory of random graphs. An extended abstract of this paper was previously published in [4]. 1

Development of a High Efficiency Ceiling Fan
The potential of ceiling fans to improve comfort during the cooling season is well documented (Rohles et al.. 1983; Fairey et al.. 1986). There are at least two cases: In the first where air conditioning is unavailable, adding ceiling fans may significantly improve building comfort and health although actually increasing energy use. However, the more common circumstance is where ceiling fans are used with the objective of providing a higher cooling system thermostat set point with acceptable comfort. Fans can also potentially avoid the use of air conditioning during "swing" seasons. Although studies commonly suggest a 2-6OF increase in the thermostat set point, data from 386 surveyed Central Florida households suggests that although fans are used an average of 13.4 hours per day, no statistically valid difference can be observed in thermostat settings between households using fans and those without them (James et al., 1996). Part of this may be due to the lack of sufficiently wide air distribution coverage within rooms (Rohles et al, 1983; Sonne and Parker, 1998). Studies touting potential cooling savings of up to 40% have usually been sponsored by fan manufacturers (eg. A.D. Little, 1981). These often make unrealistic assumptions such as presuming that occupants are within four feet of a fan with only one fan in use and a 6�F elevation of the thermostat setting. An environmental chamber study by Consumer Reports showed that the long-reported de-stratification benefits when heating are largely unsubstantiated (Consumer Reports. 1993). Thus. benefits from ceiling fans are only to reduce cooling needs and this is completely contingent on sufficient changes in interior comfort to warrant raising of the cooling thermostat. Two other factors must be taken into account in assessing the benefits of fans: their actual energy use and the added internal heat gains produced by the fans during operation. The measured electrical demand of ceiling fans varies between 5 and 115 Watts depending on model and speed selection. A power demand of 40 W at medium speed is probably typical (Chandra, 1985). Thus, a fan used for six months of the year would use 175 kwh. With 4.3 ceiling fans in an average Florida home, this amounts to about 800 kwh of fan energy consumption --about 5% of total electricity use. Also, all of the energy use of fans is eventually converted to heat within the home which must eventually be removed by ventilation air or the cooling system.

The Effect of Inlet Flow Profile Distortion on Fan Performance
Performance tests on fans for utility and industrial applications are based on codes that expect a relatively uniform velocity profile at the fan inlet. Unfortunately, when fans scaled up from the ideal model fans are installed in actual utility and industrial applications, non-uniform or distorted flow patterns often occur at the inlet of the fan. This project sought to determine and, if possible, quantify the effect on fan performance of distorted inlet flow profiles. A second goal was to determine whe...

Fan-fold shielded electrical leads
Disclosed are fan-folded electrical leads made from copper cladded Kapton, for example, with the copper cladding on one side serving as a ground plane and the copper cladding on the other side being etched to form the leads. The Kapton is fan folded with the leads located at the bottom of the fan-folds. Electrical connections are made by partially opening the folds of the fan and soldering, for example, the connections directly to the ground plane and/or the lead. The fan folded arrangement produces a number of advantages, such as electrically shielding the leads from the environment, is totally non-magnetic, and has a very low thermal conductivity, while being easy to fabricate. 3 figs.

Characterization of mutagenic activity in grain-based coffee-substitute blends and instant coffees
SciTech Connect
Several grain-based coffee-substitute blends and instant coffees showed a mutagenic response in the Ames/Salmonella test using TA98, YG1024 and YG1O29 with metabolic activation. The beverage powders contained 150 to 500 TA98 and 1150 to 4050 YG1024 revertant colonies/gram, respectively. The mutagenic activity in the beverage powders was shown to be stable to heat and the products varied in resistance to acid nitrite treatment. Characterization of the mutagenic activity, using HPLC-and the Ames test of the collected fractions, showed the coffee-substitutes and instant coffees contain several mutagenic compounds, which are most likely aromatic amines.

The detector can easily monitor soil, or other solid or liquid surfaces. 2 figures.

Fan blade development. Final report Sep 81-Sep 82
The objective of this program was to develop an improved fan blade that could be utilized in place of the current steel fan blade on the Pedal Ventilator Kit (PVK). The goals of the program were to reduce both the unit cost and weight of the fan while maintaining its effectiveness and reliability. A value analysis study was conducted on the fan blade to determine material/design revisions that offered potential manufacturing economies. Based on the conclusions of the study, two designs were chosen for fabrication. The two fan designs were constructed and tested. As a result of the performance testing, one fan blade emerged as the optimum design. Fifteen fan blades of the optimum design were constructed for FEMA inspection and distribution. Preliminary specifications were generated for the fan blade assembly. in addition, production cost estimates based on a procurement of 100,000 units were formulated for FEMA budgetary purposes.

High Efficiency Fans and High Efficiency Electrical Motors
Replacing nominal efficient electrical motors with premium efficiency can save on electrical power costs in cotton gins. Connected horsepower load on industrial air fans is approximately 60% of the total horsepower in a typical cotton gin. By replacing old inefficient centrifugal fans with new higher efficiency fans, additional power savings can be achieved.

Global Maker-Breaker games on sparse graphs
In this paper we consider Maker-Breaker games, played on the edges of sparse graphs. For a given graph property P we seek a graph (board of the game) with the smallest number of edges on which Maker can build a subgraph that satisfies P. In this paper we focus on global properties. We prove the following results: 1) for the positive minimum degree game, there is a winning board with n vertices and about 10n/7 edges, on the other hand, at least 11n/8 edges are required; 2) for the spanning k-connectivity game, there is a winning board with n vertices and (1+ok(1))kn edges; 3) for the Hamiltonicity game, there is a winning board of constant average degree; 4) for a tree T on n vertices of bounded maximum degree ?, there is a graph G on n vertices and at most f(?) � n edges, on which Maker can construct a copy of T. We also discuss biased versions on these games and argue that the picture changes quite drastically there. 1

Nonlinear fan instability of electromagnetic waves
This paper studies the linear and nonlinear stages of the fan instability, considering electromagnetic waves of the whistler frequency range interacting resonantly with energetic electron fluxes in magnetized plasmas. The main attention is paid to determine the wave-particle interaction processes that can lead to the excitation of intense electromagnetic waves by nonequilibrium particle distributions involving suprathermal tails, and to explain under what conditions and through what mechanisms they can occur, develop, and saturate. This paper presents and discusses two main processes: (i) the linear fan instability and (ii) the nonlinear process of dynamical resonance merging, which can significantly amplify the energy carried by linearly destabilized waves after they saturate due to particle trapping. This study consists of (i) determining analytically and numerically, for parameters typical of space and laboratory plasmas, the linear growth rates of whistlers excited by suprathermal particle fluxes through the fan instability, as well as the corresponding thresholds and the physical conditions at which the instability can appear, (ii) building a theoretical self-consistent 3D model and a related numerical code for describing the nonlinear evolution of the wave-particle system, and (iii) performing numerical simulations to reveal and characterize the nonlinear amplification process at work, its conditions of development, and its consequences, notably in terms of electromagnetic wave radiation. The simulations show that when the waves have reached sufficient energy levels owing to the linear fan instability, they saturate by trapping particles and due to the complex dynamics of these particles in the electromagnetic fields, the resonant velocities' domains of the waves overlap and merge, meanwhile a strong increase of the wave energy occurs.

An Aerodynamic Design Technique For Optimizing Fan Blade Spacing
INTRODUCTION Aerodynamic shape optimization involves designing the most efficient shapes of bodies that move through fluids. An optimization algorithm perturbs the shape of an airfoil until it finds the shape which best exhibits a given design objective. For an inverse design technique, this objective is a prescribed aerodynamic distribution, usually the surface pressure distribution. Liebeck pressure distributions [1], for example, have been demonstrated to generate airfoils with high lift to drag ratios. When designing fans, consideration must be given not only to the shape of the fan blades, but also to the distance separating the fan blades. This spacing is defined by the pitch/chord ratio t/l, where the pitch, t, is the distance between fan blades, and the chord, l, is the length of each fan blade. In this work, an inverse algorithm is developed, then used to design fan blade shapes and to find the optimal blade spacing. T. Rogalsky; R.W. Derksen; Rt N; Rt N; S.

Development of In-Situ Fan Curve Measurement with One Airflow Measurement
Fan airflow is the key parameter for air volume tracking control in variable air volume systems. One of the airflow measurement methods is to determine airflow using the fan speed, fan head, and fan curve. Both fan speed and fan head can be measured accurately. Therefore, the accuracy of the fan airflow depends on the accuracy of the fan curve. An experimental method has been developed to determine the in-situ fan curve with only one airflow measurement. This paper presents the theoretical background, experimental procedures, and verification results.

Supply Fan Control for Constant Air Volume Air Handling Units
Since terminal boxes do not have a modulation damper in constant volume (CV) air handling unit (AHU) systems, zone reheat coils have to be modulated to maintain the space temperature with constant supply airflow. This conventional control sequence causes a significant amount of reheat and constant fan power under partial load conditions. Variable Frequency Drives (VFDs) can be installed on these constant air volume systems. The fan speed can be modulated based on the maximum zone load. This paper present the procedure to control the supply fan speed and analyzes the thermal performance and major fan energy and thermal energy savings without expensive VAV retrofit through the actual system operation.

Fan System Effects: How Fan Ductwork Design Impacts Overall System Efficiency and What the Approach Should be for Optimization
"In order to establish the aerodynamic performance characteristics of a custom fan or even a line of fans, the accepted practice of the industry is to carry out testing on a scale model in a laboratory to develop its fan performance curve. Then by applying affinity laws in conjunction with very specific rules that address scaling issues, the performance characteristics of geometrically similar fans can be predicted. These affinity laws (frequently referred to as fan laws) also allow the performance of fans operating at different speeds or handling gases at different density values to be accurately predicted. However, it is often found that even fans with well defined and pedigreed performance curves are unable to meet their performance expectations once they are installed on the systems for which they have been sold. This is primarily due to the adverse aerodynamic impact of the inlet or outlet connections on the performance capacity of the fan and thus on the overall system efficiency. The general term for design conditions at inlets or outlets of fans that cause deficient aerodynamic performance is �system effects�. The characteristics of fan system effects are that they reduce fan capacity and are both velocity and geometry dependent. On the inlet side of a fan, this generally characterizes itself by a flow pattern that is highly non?uniform. On the discharge side, the high and low velocity flow streams leaving the fan may simply be prevented from redeveloping a uniform flow profile and normal static pressure conversion before encountering a disturbance. The term can also apply to system elements such as silencers, elbows and transitions. For these components, the actual pressure drop across them may be significantly higher than their calculated or rated values if the velocity profile of the entering flow is skewed or non?uniform. For either case (fan connection or system component), the result is that additional power will be required to address the flow rate required by the system. In many instances, system designers are simply unfamiliar with the importance of understanding system effects as it pertains to new fan selections and the attendant power requirements. At a minimum, a reasonable approach for new fan projects should be to establish the theoretical system effect of connection designs by using a recognized document such as Air Movement and Control Association Publication 201. The objective should be to first minimize their impact through appropriate connection design modifications in conjunction with potential fan inlet and outlet re?orientation. Once the system effects are minimized, the residual value should be applied to the fan performance specification in order to ensure that the fan is selected for the required aerodynamic capacity. For system components, an approach that has proved to be of significant value is to predict the flow pattern using computation fluid dynamics (CFD) modelling tools and in this process, the design can be tweaked until the designer finds the overall pressure drops of a system are minimized to the greatest practical extent. Similarly, CFD can be used to predict the flow profile at a fan inlet to ensure that it is as uniform as practically possible. This paper reviews the concept of system effects from the perspective of fan power requirements and provides a methodology for approaching system design from the perspective of optimizing fan energy use while achieving the required system capacity."

Costs and benefits of energy efficiency improvements in ceiling fans
Ceiling fans contribute significantly to residential electricity consumption, especially in developing countries with warm climates. The paper provides analysis of costs and benefits of several options to improve the efficiency of ceiling fans to assess the global potential for electricity savings and green house gas (GHG) emission reductions. Ceiling fan efficiency can be cost-effectively improved by at least 50% using commercially available technology. If these efficiency improvements are implemented in all ceiling fans sold by 2020, 70 terawatt hours per year could be saved and 25 million metric tons of carbon dioxide equivalent (CO2-e) emissions per year could be avoided, globally. We assess how policies and programs such as standards, labels, and financial incentives can be used to accelerate the adoption of efficient ceiling fans in order to realize potential savings.

Method for fabricating fan-fold shielded electrical leads
Fan-folded electrical leads made from copper cladded Kapton, for example, with the copper cladding on one side serving as a ground plane and the copper cladding on the other side being etched to form the leads. The Kapton is fan folded with the leads located at the bottom of the fan-folds. Electrical connections are made by partially opening the folds of the fan and soldering, for example, the connections directly to the ground plane and/or the lead. The fan folded arrangement produces a number of advantages, such as electrically shielding the leads from the environment, is totally non-magnetic, and has a very low thermal conductivity, while being easy to fabricate. 3 figures.

The Fan Observatory Bench Optical Spectrograph (FOBOS)
The Fan Observatory Bench Optical Spectrograph (FOBOS) is intended for single-object optical spectroscopy at moderate resolution (R~1500-3000) using a fiber-fed, bench-mounted design to maintain stability. Whenever possible, the instrument uses off-the-shelf components to maintain a modest cost. FOBOS supports Galactic astronomy projects that require consistently well-measured (~5 km/sec) radial velocities for large numbers of broadly distributed and relatively bright (Vdesign was optimized for use in the range 470-670 nm. Test data indicate that the instrument is stable and capable of measuring radial velocities with precision better than 3 km/sec at a resolution of R~1500 with minimal calibration overhead.

Particle trajectories and acceleration during 3D fan reconnection
Context. The primary energy release in solar flares is almost certainly due to magnetic reconnection, making this a strong candidate as a mechanism for particle acceleration. While particle acceleration in 2D geometries has been widely studied, investigations in 3D are a recent development. Two main classes of reconnection regimes at a 3D magnetic null point have been identified: fan and spine reconnection Aims. Here we investigate particle trajectories and acceleration during reconnection at a 3D null point, using a test particle numerical code, and compare the efficiency of the fan and spine regimes in generating an energetic particle population. Methods. We calculated the time evolution of the energy spectra. We discuss the geometry of particle escape from the two configurations and characterise the trapped and escaped populations. Results. We find that fan reconnection is less efficent than spine reconnection in providing seed particles to the region of strong electric field where acceleration is possible. The establishment of a steady-state spectrum requires approximately double the time in fan reconnection. The steady-state energy spectrum at intermediate energies (protons 1 keV to 0.1 MeV) is comparable in the fan and spine regimes. While in spine reconnection particle escape takes place in two symmetric jets along the spine, in fan reconnection no jets are produced and particles escape in the fan plane, in a ribbon-like structure.

Use of VFDs on Asphalt Plant Induced Draft Fans
Studies of 10 asphalt plants in the Intermountain Region have identified average ID fan energy savings of 68% by controlling airflow using Variable Frequency Drives (VFDs) on the fan motors in place of damper control (inlet or outlet). Average paybacks were 3-5 years before utility incentives. In the 10 plants evaluated, the ID fans accounted for as much as 30% of the total plant electrical consumption. In the majority of these plants the outlet dampers were typically 50%-60% closed. Fan motors ranged from 200 Hp to 500 Hp. With approximately 3,600 existing asphalt plants in operation across the United States, a large opportunity for retrofits exists. Working with manufacturers and owners, a new standard can be established for installing VFDs on all plants.

Crossover distributions at the edge of the rarefaction fan
We consider the weakly asymmetric limit of simple exclusion process with drift to the left, starting from step Bernoulli initial data with $\\rho_-fan. We study the fluctuations of the process observed along slopes in the fan, which are given by the Hopf--Cole solution of the Kardar-Parisi-Zhang (KPZ) equation, with appropriate initial data. For slopes strictly inside the fan, the initial data is a Dirac delta function and the one point distribution functions have been computed in [Comm. Pure Appl. Math. 64 (2011) 466-537] and [Nuclear Phys. B 834 (2010) 523-542]. At the edge of the rarefaction fan, the initial data is one-sided Brownian. We obtain a new family of crossover distributions giving the exact one-point distributions of this process, which converge, as $T\

Designing Axial Flow Fan for Flow and Noise
A comprehensive finite element methodology is developed to predict the compressible flow performance of a non-symmetric 7-blade axial flow fan, and to quantify the source strength and sound pressure levels at any location in the system. The acoustic and flow performances of the fan are predicted simultaneously using a computational aero-acoustic technique combining transient flow analysis and noise propagation. The calculated sound power levels compare favorably with the measured sound power data per AMCA 300-96 code.

Best Practice for Energy Efficient Cleanrooms: Fan-FilterUnits
The HVAC systems in cleanrooms may use 50 percent or more of the total cleanroom energy use. Fan energy use accounts for a significant portion (e.g., over 50%) of the HVAC energy use in cleanrooms such as ISO Classes 3, 4, or 5. Three types of air-handling systems for recirculating airflows are commonly used in cleanrooms: (1) fan-tower systems with pressurized plenum, (2) ducted HEPA systems with distributed-fans, and (3) systems with fan-filter units. Because energy efficiency of the recirculation systems could vary significantly from system type to system type, optimizing aerodynamic performance in air recirculation systems appears to be a useful approach to improve energy efficiency in cleanrooms. Providing optimal airflows through careful planning, design and operation, including air change rate, airflow uniformity, and airflow speed, is important for controlling particle contamination in cleanrooms. In practice, the use of fan-filter units (FFUs) in the air-handling system is becoming more and more popular because of this type of system may offer a number of advantages. Often modular and portable than traditional recirculation airflow systems, FFUs are easier to install, and can be easily controlled and monitored to maintain filtration performance. Energy efficiency of air handling systems using fan-filter units can, however, be lower than their counterparts and may vary significantly from system to system because of the difference in energy performance, airflow paths, and the operating conditions of FFUs.
Upcoming emissions regulations (Tiers 3, 4a and 4b) are imposing significantly higher heat loads on the cooling system than lesser regulated machines. This work was a suite of tasks aimed at reducing the parasitic losses of the cooling system, or improving the design process through six distinct tasks: 1. Develop an axial fan that will provide more airflow, with less input power and less noise. The initial plan was to use Genetic Algorithms to do an automated fan design, incorporating forward sweep for low noise. First and second generation concepts could not meet either performance or sound goals. An experienced turbomachinery designer, using a specialized CFD analysis program has taken over the design and has been able to demonstrate a 5% flow improvement (vs 10% goal) and 10% efficiency improvement (vs 10% goal) using blade twist only. 2. Fan shroud developments, using an 'aeroshroud' concept developed at Michigan State University. Performance testing at Michigan State University showed the design is capable of meeting the goal of a 10% increase in flow, but over a very narrow operating range of fan performance. The goal of 10% increase in fan efficiency was not met. Fan noise was reduced from 0 to 2dB, vs. a goal of 5dB at constant airflow. The narrow range of fan operating conditions affected by the aeroshroud makes this concept unattractive for further development at this time 3. Improved axial fan system modeling is needed to accommodate the numbers of cooling systems to be redesigned to meet lower emissions requirements. A CFD fan system modeling guide has been completed and transferred to design engineers. Current, uncontrolled modeling practices produce flow estimates in some cases within 5% of measured values, and in some cases within 25% of measured values. The techniques in the modeling guide reduced variability to the goal of + 5% for the case under study. 4. Demonstrate the performance and design versatility of a high performance fan. A 'swept blade mixed flow' fan was rapid prototyped from cast aluminum for a performance demonstration on a small construction machine. The fan was mounted directly in place of the conventional fan (relatively close to the engine). The goal was to provide equal airflow at constant fan speed, with 75% of the input power and 5 dB quieter than the conventional fan. The result was a significant loss in flow with the prototype due to its sensitivity to downstream blockage. This sensitivity to downstream blockage affects flow, efficiency, and noise all negatively, and further development was terminated. 5. Develop a high efficiency variable speed fan drive to replace existing slipping clutch style fan drives. The goal for this task was to provide a continuously variable speed fan drive with an efficiency of 95%+ at max speed, and losses no greater than at max speed as the fan speed would vary throughout its entire speed range. The process developed to quantify the fuel savings potential of a variable speed fan drive has produced a simple tool to predict the fuel savings of a variable speed drive, and has sparked significant interest in the use of variable speed fan drive for Tier 3 emissions compliant machines. The proposed dual ratio slipping clutch variable speed fan drive can provide a more efficient system than a conventional single ratio slipping clutch fan drive, but could not meet the established performance goals of this task, so this task was halted in a gate review prior to the start of detailed design. 6. Develop a cooling system air filtration device to allow the use of automotive style high performance heat exchangers currently in off road machines. The goal of this task was to provide a radiator air filtration system that could allow high fin density, louvered radiators to operate in a find dust application with the same resistance to fouling as a current production off-road radiator design. Initial sensitivity testing demonstrated that fan speed has a significant impact on the fouling of radiator cores due to fine dusts, so machines equipped with continuously variabl

Induced draft fan innovation for heat recovery steam generators
A first of its kind, induced draft (ID) heat recovery steam generators (HRSG) have been in service at a cogeneration facility since 1991. A preliminary engineering study considered a forced draft (FD) fan to supply combustion air to the HRSG duct burners (when the combustion turbine (CT) is out of service) as a traditional design; however, the study indicated that the FD fan may require the HRSG duct burner to be shut off following a CT trip and re-ignited after the FD fan was in service. Although the induced draft HRSG design cost more than the FD fan design, the induced draft design has improved the cogeneration facility's steam generation reliability by enabling the HRSG to remain in service following a CT trip. This paper briefly summarizes the preliminary engineering study that supported the decision to select the ID fan design. The paper also discusses the control system that operates the fresh-air louvers, duct burners, HRSG, and ID fan during a CT trip. Startup and operating experiences are presented that demonstrate the effectiveness of the design. Lessons learned are also summarized for input into future induced draft HRSG designs.

Measured Natural Cooling Enhancement of a While House Fan
An experimental study was carried out in the summer of 1991 to investigate the natural cooling potential of use of a whole house fan in Central Florida's hot and humid climate. The residential building, in Cocoa Beach, FL, is typical of much of the existing housing stock in Florida: a concrete block structure with R-11 ceiling insulation. The building was ventilated with all windows open during the three month summer test period (June- August). Air temperatures and relative humidity inside the home interior along with exterior meteorological conditions (insolation, wind speed, air temperature, relative humidity) were scanned every five seconds with integrated averages recorded on a multi-channel data logger every 15- minutes. The house was naturally ventilated during the first half of summer. After a significant period of pre-retrofit summer data had been collected characterizing the building's thermal response, a 24" whole house fan was installed. The house was then force ventilated during evening hours for the remainder of the summer to establish potential of whole-house fans to improve interior comfort conditions. The electrical consumption of the fan was measured at both available fan speeds. Measurements revealed that the building interior was 3 - 6�F cooler during the evening hours after the whole house fan was operated. However, data also showed that nighttime humidity levels rose: relative humidity increased from 74% to 83% during the nighttime period where fan-powered ventilation was used. Using the data results, an analysis was performed using Orlando, Florida TMY data to see how limits to whole house ventilation based on humidity and temperature conditions would affect the potential of such a cooling strategy.

Cooling Tower Energy Conservation Through Hydraulic Fan Drives
Many companies offer gearboxes, shafts, and couplings for cooling tower fan drives, with little or no innovation. These companies have traditionally been purchased with an emphasis on cost and not "Return on Investment!" In the past, when energy conservation or "Return on Investment" was emphasized, the only alternative was to add an expensive frequency inverter for variable speed control. This meant expensive rewiring, placing additional controls in an already crowded control room, or constructing a special building for them. However, with H.E.M.'s patented Hydraulic Fan Drive, one receives variable speed control and more efficiency for approximately the price of a mechanical drive. The new, more efficient Hydraulic Drive allows for a variable speed control and the ability to sense water temperature to control fan speed.

The sample included two rear downdraft systems, two under-cabinet microwave over range (MOR) units, three different installations of an under-cabinet model with grease screens across the bottom and no capture hood, two devices with grease screens covering the bottom of a large capture hood (one under-cabinet, one wall-mount chimney), four under-cabinet open hoods, and two open hoods with chimney mounts over islands. Performance assessment included measurement of airflow and sound levels across fan settings and experiments to quantify the contemporaneous capture efficiency for the exhaust generated by natural gas cooking burners. Capture efficiency is defined as the fraction of generated pollutants that are removed through the exhaust and thus not available for inhalation of household occupants. Capture efficiency (CE) was assessed for various configurations of burner use (e.g. single front, single back, combination of one front and one back, oven) and fan speed setting. Measured airflow rates were substantially lower than the levels noted in product literature for many of the units. This shortfall was observed for several units costing in excess of $1000. Capture efficiency varied widely (from <5% to roughly 100%) across devices and across conditions for some devices. As expected, higher capture efficiencies were achieved with higher fan settings and the associated higher air flow rates. In most cases, capture efficiencies were substantially higher for rear burners than for front burners. The best and most consistent performance was observed for open hoods that covered all cooktop burners and operated at higher airflow rates. The lowest capture efficiencies were measured when a front burner was used with a rear backdraft system or with lowest fan setting for above the range systems that do not cover the front burners.

Performance of ECM controlled VAV fan powered terminal units
Empirical performance models of fan airflow, primary airflow and power consumption were developed for series and parallel variable air volume fan powered terminal units. An experimental setup and test procedure were created to test the terminal units at typical design pressures and airflows. Each terminal unit observed in this study used an 8 in (20.3 cm) primary air inlet. Two fan motor control methods were considered. The primary control of interest was the electronically commutated motor (ECM) controller. Data collected were compared with previous research regarding silicon rectified control (SCR) units. Generalized models were developed for both series and parallel terminal units. Coefficients for performance models were then compared with comparable SCR controlled units. Non-linear statistical modeling was performed using SPSS software (2008). In addition to airflow and power consumption modeling, power quality was also quantified. Relationships between real power (watts) and apparent power (VA) were presented as well as harmonic frequencies and total harmonic distortion. Power quality was recorded for each ECM controlled terminal unit tested. Additional tests were also made to SCR controlled terminal units used in previous research (Furr 2006). The airflow and power consumption performance models had an R2 equal to 0.990 or greater for every terminal unit tested. An air leakage model was employed to account for leakage in the parallel designed VAV terminal units when the internal fan was turned off. For the leakage model, both ECM and SCR controlled units achieved an R2 greater than or equal to 0.918.

The Forming of AISI 409 sheets for fan blade manufacturing
The necessity of adapting the standardized fan models to conditions of higher temperature has emerged due to the growth of concern referring to the consequences of the gas expelling after the Mont Blanc tunnel accident in Italy and France, where even though, with 100 fans in operation, 41 people died. The objective of this work is to present an alternative to the market standard fans considering a new technology in constructing blades. This new technology introduces the use of the stainless steel AISI 409 due to its good to temperatures of gas exhaust from tunnels in fire situation. The innovation is centered in the process of a deep drawing of metallic sheets in order to keep the ideal aerodynamic superficies for the fan ideal performance. Through the impression of circles on the sheet plane it is shown, experimentally, that, during the pressing process, the more deformed regions on the sheet plane of the blade can not reach the deformation limits of the utilized sheet material.

When the Underwriter is the Market Maker: An Examination of Trading in the IPO Aftermarket
This paper examines aftermarket trading of underwriters and unaffiliated market makers in the three month period after an IPO. We find that the lead underwriter is always the dominant market maker, he takes substantial inventory positions in the aftermarket trading, and co-managers play a negligible role in aftermarket trading. The lead underwriter engages in stabilization activity for less successful IPOs, and uses the overallotment option to reduce his inventory risk. Compensation to the underwriter arises primarily from fees, but aftermarket trading does generate positive profits, which are positively related to the degree of underpricing.

Social values and solar energy policy: the policy maker and the advocate
Solar energy policy makers and advocates have significantly different hierarchies (clusters) of values upon which they evaluate the adoption of solar technologies. Content analysis, which examines the frequency with which policy makers identify different types of values, indicates that they hold economic values to be of primary importance. Environmental, social, and national security values are also substantial elements of the policy makers' value clusters associated with solar energy. This finding is confirmed by a qualitative analysis of policy makers' values. Advocates, on the other hand, assign almost equal weights (33%) to economic values and social values, slightly less weight to environmental values, and significant attention to ethical and security values as well. These results of frequency analysis are made somewhat more complicated by a qualitative interpretation of the advocates' positions. As part of their more holistic approach, several of the advocates indicated that all values discussed by them are instrumental toward achieving higher-order, ethical and environmental values. In addition, our preliminary investigation indicates that neither group is entirely homogeneous. Testing this and other propositions, as well as obtaining a similar picture of the values which the public associates with solar energy, are topics of future research.

The installed performance of cooking exhaust fans was evaluated through residential field experiments conducted on a sample of 15 devices varying in design and other characteristics. The sample included two rear downdraft systems, two under-cabinet microwave over range (MOR) units, three different installations of an under-cabinet model with grease screens across the bottom and no capture hood, two devices with grease screens covering the bottom of a large capture hood (one under-cabinet, one wall-mount chimney), four under-cabinet open hoods, and two open hoods with chimney mounts over islands. Performance assessment included measurement of airflow and sound levels across fan settings and experiments to quantify the contemporaneous capture efficiency for the exhaust generated by natural gas cooking burners.Capture efficiency is defined as the fraction of generated pollutants that are removed through the exhaust and thus not available for inhalation of household occupants. Capture efficiency (CE) was assessed for various configurations of burner use (e.g., single front, single back, combination of one front and one back, oven) and fan speed setting. Measured airflow rates were substantially lower than the levels noted in product literature for many of the units. This shortfall was observed for several units costing in excess of $1000. Capture efficiency varied widely (fromfan settings and the associated higher air flow rates. In most cases, capture efficiencies were substantially higher for rear burners than for front burners. The best and most consistent performance was observed for open hoods that covered all cooktop burners and operated at higher airflow rates. The lowest capture efficiencies were measured when a front burner was used with a rear backdraft system or with lowest fan setting for above the range systems that do not cover the front burners.

Chris Stewart Senior Communicator at DOE's National Renewable Energy Laboratory As part of some recent money- and energy-savings improvements I've been making to my home, a couple of weeks ago I installed a ceiling fan in my main living room. Part of my research led me to understand how ceiling fans are considered the most effective fans compared among table fans, floor fans, and fans mounted to poles or walls because they effectively circulate the air in a room to create a draft throughout the room.
Savings in electric cooling energy by the use of a whole-house fan. Final report
Hour-by-hour cooling performances of a typical ranch house, with and without the use of a whole-house fan, were compared for the climate conditions throughout the contiguous United States. The comparative analyses were made by the use of NBSWHF, a modified version of NBSLD, to simulate the complex thermal coupling of whole-house-fan ventilated attic space. The calculations were performed for two operational modes: a cyclic fan mode and a stepwise continuous mode.

How Has a Ceiling Fan Affected the Way You Heat and Cool Your Home? |
Has a Ceiling Fan Affected the Way You Heat and Cool Your Home? Has a Ceiling Fan Affected the Way You Heat and Cool Your Home? How Has a Ceiling Fan Affected the Way You Heat and Cool Your Home? September 23, 2010 - 7:30am Addthis On Monday, Chris told you about his new ceiling fan and how it's changed the way he cools his home. In warm weather, ceiling fans cool people (not rooms) by producing a wind-chill effect-which is why you should turn off fans when you leave the room. A ceiling fan allows you to raise the thermostat setting about 4°F with no reduction in comfort. Ceiling fans don't just cool in the summer; you can also reverse the direction in the winter to provide an updraft and force warm air down into the room. How has a ceiling fan affected the way you heat and cool your home? Each Thursday, you have the chance to share your thoughts on a question

Performance of a stand-alone wind-electric ice maker for remote villages
Two ice makers in the 1.1 metric tons per 24 hours (1.2 tons per day) size range were tested to determine their performance when directly coupled to a variable-frequency wind turbine generator. Initial tests were conducted using a dynamometer to simulate to wind to evaluate whether previously determined potential problems were significant and to define basic performance parameters. Field testing in Norman, Oklahoma, was completed to determine the performance of one of the ice makers under real wind conditions. As expected, the ice makers produced more ice at a higher speed than rated, and less ice at a lower speed. Due to the large start-up torque requirement of reciprocating compressors, the ice making system experienced a large start-up current and corresponding voltage drop which required a larger wind turbine that expected to provide the necessary current and voltage. Performance curves for ice production and power consumption are presented. A spreadsheet model was constructed to predict ice production at a user-defined site given the wind conditions for that location. Future work should include long-term performance tests and research on reducing the large start-up currents the system experiences when first coming on line.

Arbitrary surface flank milling of fan, compressor, and impeller blades
It is generally conceived that a blade surface is flank millable if it can be closely approximated by a ruled surface; otherwise the slow machining process of point milling has to be employed. However, the authors have now demonstrated that the ruled surface criterion for flank milling is neither necessary nor sufficient. Furthermore, many complex arbitrary surfaces typical of the blades in fans, axial compressors, and centrifugal impellers in aviation gas turbines are actually closely flank millable and can be rendered exactly flank millable with one or more passes per surface often without sacrificing, indeed usually with gain, in performance.

This study is a statistical analysis of the sandstone distribution within the Arkansas Jackfork Group which is a passive margin fan complex. Passive margin fan systems are typically associated with long fluvial transport, fed by deltas, wide shelf, efficient basin transport, that result in a bypassing system. Passive margin fans are generally fine-grained, mud rich, and well sorted. These fans can be separated into three units (upper, middle, and lower fan) based on their location within the fan and how the sediments are deposited. Five outcrops from the Arkansas Jackfork Group have been chosen for this study and each were divided into different facies dependent on sandstone percentages in certain bed sets. The amount of sandstone for each facies was calculated and a statistical approximation for each outcrop was determined. Sandstone distribution curves were made for each outcrop to show a graphic representation of how the sandstone is dispersed. After analyzing different upper, middle, and lower fan outcrops, it is clear there is an obvious change in the sandstone percentage and distribution. The upper fan deposit has an overall sandstone percentage of approximately 77.5% and is deposited in beds that are mainly amalgamated; 10-30m thick. Sandstone is deposited moderately even and is quite concentrated throughout the exposure. The middle fan outcrops contain approximately 72.6% sandstone and show similar patterns, except that the amalgamated sandstone beds are not as thick, 5-15m and contain more shale in between layers. As expected the lower fan outcrop is completely different in both sandstone percentage and distribution. The lower fan has approximately 65.4% sandstone. The distribution of sandstone is more concentrated in each of the individual units, or systems, but the overall complex has two systems separated by a massive marine shale bed, 33.5 m, that contains virtually no sand.

Performance Analysis of Dual-Fan, Dual-Duct Constant Volume Air-Handling Units
Dual-fan, dual-duct air-handling units introduce outside air directly into the cooling duct and use two variable speed devices to independently maintain the static pressure of the hot and the cold air ducts. Analytical models have been developed to compare fan power and thermal energy consumption of dualfan, dual-duct constant volume air-handling units with single-fan, dual-duct constant volume airhandling units. This study shows that the dual-fan, dual-duct system uses less fan power and less thermal energy during winter, and uses more thermal energy during summer. Thermal energy performance can be significantly improved if the thermal energy penalty can be decreased or eliminated.

Impact-resistant boron/aluminum composites for large fan blades
Blade-like specimens were subjected to static ballistic impact testing to determine their relative FOD impact resistance levels. It was determined that a plus or minus 15 deg layup exhibited good impact resistance. The design of a large solid boron/aluminum fan blade was conducted based on the FOD test results. The CF6 fan blade was used as a baseline for these design studies. The solid boron/aluminum fan blade design was used to fabricate two blades. This effort enabled the assessment of the scale up of existing blade manufacturing details for the fabrication of a large B/Al fan blade. Existing CF6 fan blade tooling was modified for use in fabricating these blades.

A passive margin-type submarine fan complex, Permian Ecca Group, South Africa
A submarine fan complex, comprising five arenaceous fan systems separated by basinal shale units, occurs in the southwestern part of the intracratonic Karoo basin in South Africa. Although basin development is related to a subduction zone bordering the palaeo-Pacific ocean to the south of Gondwanaland and the evolution of the Cape Fold Belt, the entire Lower Permian Ecca Group basin-fill succession reflects depositional characteristics of a passive-margin setting. The submarine fan complex, 250 m thick, originated from sediments supplied by Mississippi-type deltas dominating the Ecca coastline. The fine grain-size and low sand/shale ratio of the submarine fan and deltaic deposits reflect the maturity of the ancient river systems. Outcrops of the fan complex are well exposed and cover an area of 650 km{sup 2}. The strata are not affected by folding, and deep erosion allows three-dimensional viewing of mid-fan to outer-fan deposits. Features of interest include stacked lobe deposits displayed along 2.5 km of a 60 m high cliff section, and a transverse cliff section through channel-fill deposits 500 m wide. Paleocurrent directions reveal that each sequence had its own main source area located to the northwest and south of its present geographic location. The cyclic nature of the fan complex is attributed to relative sea-level changes; deposition took place on the basin floor in water depths that do not exceed 500 m. Shoaling of the basin to wave base depths is reflected in the pro-delta and delta front deposits overlying the uppermost fan sequence. Major factors in controlling direction of fan progradation were delta switching and basin floor topography.

Fan-shaped and toric textures of mesomorphic oxadiazoles
When a family of non symmetrical heterocycled compounds is investigated, a variety of mesophases can be observed with rather different features. Here we report the behaviour of seven different members among a family of such materials, that consists of mesomorphic oxadiazole compounds. In two of these compounds, the optical microscope investigation shows very interesting behaviours. In their smectic phases, fan-shaped and toric textures, sometimes with periodic instability, are observed. Moreover, the nematic phase displays a texture transition. Texture transitions have been previously observed only inside the nematic phase of some compounds belonging to the families of the oxybenzoic and cyclohexane acids. In these two oxadiazole compounds we can observe what we define as a "toric nematic phase", heating the samples from the smectic phase. The toric nematic texture disappears as the sample is further heated, changing into a smooth texture.

A Strategy for Maker in the Clique Game which Helps to Tackle some Open Problems by Beck
We study Maker/Breaker games on the edges of the complete graph, as introduced by Chvatal and Erdos. We show that in the (m:b) clique game played on K_{N}, the complete graph on N vertices, Maker can achieve a K_{q} for q = (m/(log_{2}(b + 1)) - o(1)) * log N, which partially solves an open problem by Beck. Moreover, we show that in the (1:1) clique game played on K_{N} for a sufficiently large N, Maker can achieve a K_{q} in only 2^(2q/3) moves, which improves the previous best bound and answers a question of Beck. Finally we consider the so called tournament game. A tournament is a directed graph where every pair of vertices is connected by a single directed edge. The tournament game is played on K_{N}. At the beginning Breaker fixes an arbitrary tournament T_{q} on q vertices. Maker and Breaker then alternately take turns at claiming one unclaimed edge e and selecting one of the two possible orientations. Maker wins if his graph contains a copy of the goal tournament T_{q}; otherwise Breaker wins. We show ...

Quiet Computing with BSD: Fan control with sysctl hw.sensors.
We will discuss the topic of fan control and introduce sysctl-based interfacing with the fancontrolling capabilities of microprocessor system hardware monitors on OpenBSD. The discussed prototype implementation reduces the noise and power-consumption characteristics in fans of personal computers, especially of those PCs that are designed from off-the-shelf components. We further argue that our prototype is easier, robuster and more intuitive to use compared to solutions available elsewhere. 1.

Root-Cause Failure Analysis: Fossil-Fired Power Plant Draft Fans
This report describes the collection and analysis of fan-related outage data for 61 large fossil fuel steam power plants. The outage causes are ranked in terms of their impact on production, and a systematic search for generic root causes is described. Recommendations are made for short-term corrective measures and for longer-term research efforts to significantly improve fan system reliability.
Application of Adjustable Speed Drives to Induced Draft Fans at NSP-SHERCO Power Plant
Induced draft (ID) fans on power boilers control the flow of flue gasses from the boiler to the atmosphere-and their smooth operation is essential to the efficient operation of any generating station. Adjustable speed drive (ASD) control of an electric motor ID fan can provide significant energy savings while increasing the accuracy and precision of boiler draft and fuel gas flow regulation. This study quantified the energy savings and identified other benefits of applying ASDs to four existing electric-...

A substantial fraction of HVAC energy use in large commercial buildings is due to fan operation. Fan energy use depends in part on the relationship between system pressure drop and flow through the fan, which is commonly called a "system curve." As a step toward enabling better selections of air-handling system components and analyses of common energy efficiency measures such as duct static pressure reset and duct leakage sealing, this paper shows that a simple four-parameter physical model can be used to define system curves. Our model depends on the square of the fan flow, as is commonly considered. It also includes terms that account for linear-like flow resistances such as filters and coils, and for supply duct leakage when damper positions are fixed or are changed independently of static pressure or fan flow. Only two parameters are needed for systems with variable-position supply dampers (e.g., VAV box dampers modulating to control flow). For these systems, reducing or eliminating supply duct leakage does not change the system curve. The parametric system curve may be most useful when applied to field data. Non-linear techniques could be used to fit the curve to fan pressure rise and flow measurements over a range of operating conditions. During design, when measurements are unavailable, one could use duct design calculation tools instead to determine the coefficients.

Channel complex architecture of fine-grained submarine fans at the base-of-slope
The fan-valley or upper fan channel connects the submarine canyon on the outer shelf-upper slope to the basin proper. It is an erosionally-formed channel that is a conduit for sediment transported to the basin. The valley may widen where it enters the base-of-slope area. Most of the density flows are much smaller than the initial flow and therefore will not occupy the entire width of the upper fan channel. Smaller individual channels will be constructed resulting in a massive fill comprised of amalgamated sandstones. Sand-rich levees and overbank deposits flank each channel. Channel switching may take place toward locations with a slightly steeper gradient. These switches most likely result from irregular flow successions and different flow sizes. Erosion between successive channels is common, removing part of the channel fill and levee-overbank deposits. This results in a disorderly distribution of low-permeability barriers creating local obstruction to connectivity. A study of the sedimentological architecture of the updip mid-fan channel complex was conducted on cliff sections of the Permian Tanqua Karoo subbasin in South Africa, and in Big Rock Quarry in North Little Rock, Arkansas. Seismic records of the base-of-slope of the Mississippi Fan show a widening pattern, and of the Bryant Canyon Fan Complex south of the Sigsbee Escarpment the channel complexity. Integration of seismic data in outcrop observations improves our understanding of the complexity of many good reservoir sands, typically overlain by slope shales.

Applicability of fan spray nozzles to stripping insoluble gases from viscous liquids
Fan spray nozzle stripping appears to be a practical technique for separating dilute volatile solutes from nonvolatile solvents. In particular this technique can be used to strip molecular tritium and tritium fluoride at extremely small concentration (in the parts per million range) from molten salts used as blanket materials in a fusion reactor. Under adjusted operating conditions of the fan spray as it leaves the nozzle, a high percentage of the theoretically maximum achievable stripping would take place from the expanding sheet of the fan spray as it leaves the nozzle and before it breaks up. Although the only available experimental data are for aqueous solutions, a new theoretical analysis of the fan spray sheet demonstrates the applicability of this technique to nonaqueous liquids. The equation derived from this analysis relates the theoretically achievable mass transfer efficiency to the properties of the liquid flowing through the fan spray nozzle and to the operating conditions of the nozzle. Any fluid with viscosity higher than or equal to that of water would be expected to follow this equation as long as a fan-shaped sheet is formed under the operating conditions of the nozzle.

The noise power spectrum in CT with direct fan beam reconstruction
The noise power spectrum (NPS) is a useful metric for understanding the noise content in images. To examine some unique properties of the NPS of fan beam CT, the authors derived an analytical expression for the NPS of fan beam CT and validated it with computer simulations. The nonstationary noise behavior of fan beam CT was examined by analyzing local regions and the entire field-of-view (FOV). This was performed for cases with uniform as well as nonuniform noise across the detector cells and across views. The simulated NPS from the entire FOV and local regions showed good agreement with the analytically derived NPS. The analysis shows that whereas the NPS of a large FOV in parallel beam CT (using a ramp filter) is proportional to frequency, the NPS with direct fan beam FBP reconstruction shows a high frequency roll off. Even in small regions, the fan beam NPS can show a sharp transition (discontinuity) at high frequencies. These effects are due to the variable magnification and therefore are more pronounced as the fan angle increases. For cases with nonuniform noise, the NPS can show the directional dependence and additional effects.

Limit processes for TASEP with shocks and rarefaction fans
We consider the totally asymmetric simple exclusion process (TASEP) with two-sided Bernoulli initial condition, i.e., with left density rho_- and right density rho_+. We consider the associated height function, whose discrete gradient is given by the particle occurrences. Macroscopically one has a deterministic limit shape with a shock or a rarefaction fan depending on the values of rho_{+/-}. We characterize the large time scaling limit of the fluctuations as a function of the densities rho_{+/-} and of the different macroscopic regions. Moreover, using a slow decorrelation phenomena, the results are extended from fixed time to the whole space-time, except along the some directions (the characteristic solutions of the related Burgers equation) where the problem is still open. On the way to proving the results for TASEP, we obtain the limit processes for the fluctuations in a class of corner growth processes with external sources, of equivalently for the last passage time in a directed percolation model with two-sided boundary conditions. Additionally, we provide analogous results for eigenvalues of perturbed complex Wishart (sample covariance) matrices.

Thai decision makers in the United States: attitudes toward technology transfer in a newly industrializing country
The problem of the study was to determine the attitudes of Thai policy makers toward technology transfer into newly industrializing countries such as Thailand. These opinions were considered crucial in determining the direction of industrialization of the country. The study was conducted with a sample of Thai government administrators and business leaders employed in the State of California. Analysis consisted of an item by item comparison of responses and of a ranking of suitable types of technology for Thailand. The study attempted to ascertain attitudes and to determine any similarities and differences between the responses of the two groups. The study concerned itself with three broad questions: (1) do Thai government administrators agree with one another about technology transfer; (2) do Thai business leaders agree with one another; and (3) how do the attitudes of government administrators and business leaders compare. The findings indicated that no appreciable differences could be measured among the government administrators in technology transfer issues. Similarly, business respondents also strongly agreed with one another regarding aspects of technology transfer. Lastly, there was no real difference between the attitudes of business leaders and government administrators.

Characteristics of some submarine fan channels, Permian Ecca Group, South Africa
The vary well exposed submarine fan complex in the southwestern part of the Karoo basin permits close examination of channel-fills and in places their associated overbank deposits. The complex comprises five arenaceous fan systems some of which attain 60 m in thickness. The fans are vertically stacked and separated by basinal shale deposits; each system with its own direction of growth. The association of channelized sandstone bodies and thin-bedded sandstone and shale packages in an updip position from predominantly stacked lobe deposits suggest preservation of middle fan settings. A 500 m wide, 20 m thick channel-fill consisting massive amalgamated sandstone beds occupying the channel thalweg occurs in a setting dominated by thin-bedded, ripple-laminated sandstone and shale. Gradual thinning of the channel-fill beds toward the channel edges, lack of internal lateral accretion, and a high width to depth ratio suggests a low sinuous to straight channel. The channel-fill is capped by an abandonment facies characterized by ripple-laminated sandstone and shale. Stacked, laterally offset channel-fill deposits with highly erosional contacts and typical well-bedded overbank deposits form channel-overbank complexes and characterize the mid-fan region of the uppermost fan system. Palaeocurrent directions and gradual diminishing of bed-thickness away from the generally massively bedded, amalgamated channel-fill sandstones confirm a simultaneous channel/overbank origin for these deposits. Levee morphology has not been recognized. Both examples of channel-fills cited reveal part of the complexity of the channelized portions of submarine fans and hence the implications thereof in exploring for hydrocarbon reservoirs.

Modeling of ECM Controlled Series Fan-powered VAV Terminal Units
Semi-empirical models for series fan-powered variable air volume terminal units (FPTUs) were developed based on models of the primary, plenum, fan airflow and the fan power consumption. The experimental setups and test procedures were developed respectively for primary, plenum and fan airflow to test each component of the FPTUs at typical design pressures and airflows. Two sizes of the terminal units from three manufacturers were used in this study. All of the FPTUs were equipped with electronically commutated motors (ECM). Data provided by the models were compared against the data from previous experiments to prove the models� validity. Regression modeling was performed by using SigmaStat. The model of primary airflow had an R2 above 0.948 for all the terminal units evaluated while the plenum airflow model had an R2 above 0.99. For all the terminal units, the R2 of the fan airflow model was ranged from 0.973 to 0.998. Except for one fan, the fan power consumption model was able to characterize the power performance and had an R2 above 0.986. By combining the airflow and power models, the model for series FPTU was developed. Verification was made to prove the FPTU model�s validity by comparing the measured and predicted data of airflow and power consumption. Correction factors were used in the primary airflow model to compensate for the difference caused by large measurement errors and the system effects. The predicted values were consistent with measurements and no offset was needed in the primary airflow model. Generally, the newly established model was able to describe the airflow performance as well as power consumption of series FPTUs without adding complexity.

Modeling of Electronically Commutated Motor Controlled Fan-powered Terminal Units
Empirical models of airflow and power consumption were developed for series and parallel variable air volume fan powered terminal units (FPTUs). An experimental setup and test procedure were developed to test the terminal units over typical operating ranges. The terminal units in this study used either an 8 in. (20.32 cm) or a 12 in. (30.48 cm) primary air inlet. All terminal units utilized electronically commutated motor (ECM) controllers. Data collected were compared against previous data collected for silicon controlled rectifier (SCR) units. Generalized models were developed for both series and parallel units, and compared against models developed for SCR units. In addition to the performance modeling, power factor and power quality data were also collected for each terminal unit. The power quality analysis included recording and analyzing harmonic distortion for current, voltage, and power up to the 25th harmonic. The total harmonic distortion (THD) was also recorded and presented. For the series terminal units, models were developed for fan airflow, fan power, and primary airflow. The models for fan airflow all had R2 values above 0.987. The models for fan power all had R2 values above 0.968. The models for primary airflow all had R2 values above 0.895. For the parallel terminal units, models were developed for leakage, fan airflow, fan power, and primary airflow. All of the leakage models had R2 values above 0.826. All of the fan airflow models had R2 values above 0.955. All of the fan power models had R2 values above 0.922. All of the primary airflow models had R2 values above 0.872. The real power THD was below 1.5 percent for both series and parallel FPTUs. The current THD ranged from 84 percent to 172 percent for series FPTUs and from 83 percent to 183 percent for parallel FPTUs. The voltage THD was below 1.4 percent for both series and parallel FPTUs. The performance models developed will help improve the accuracy of building energy simulation programs for heating, ventilation, and air conditioning (HVAC) systems utilizing ECM controlled FPTUs. Increasing the accuracy of these simulations will allow HVAC system designers to better optimize their designs for specific building types in a wide variety of climates.

Procuring Stationary Fuel Cells For CHP: A Guide for Federal Facility Decision Makers
Federal agency leaders are expressing growing interest in using innovative fuel cell combined heat and power (CHP) technology at their sites, motivated by both executive branch sustainability targets and a desire to lead by example in the transition to a clean energy economy. Fuel cell CHP can deliver reliable electricity and heat with 70% to 85% efficiency. Implementing this technology can be a high efficiency, clean energy solution for agencies striving to meet ambitious sustainability requirements with limited budgets. Fuel cell CHP systems can use natural gas or renewable fuels, such as biogas. Procuring Stationary Fuel Cells for CHP: A Guide for Federal Facility Decision Makers presents an overview of the process for planning and implementing a fuel cell CHP project in a concise, step-by-step format. This guide is designed to help agency leaders turn their interest in fuel cell technology into successful installations. This guide concentrates on larger (100 kW and greater) fuel cell CHP systems and does not consider other fuel cell applications such as cars, forklifts, backup power supplies or small generators (<100 kW). Because fuel cell technologies are rapidly evolving and have high up front costs, their deployment poses unique challenges. The electrical and thermal output of the CHP system must be integrated with the building s energy systems. Innovative financing mechanisms allow agencies to make a make versus buy decision to maximize savings. This guide outlines methods that federal agencies may use to procure fuel cell CHP systems with little or no capital investment. Each agency and division, however, has its own set of procurement procedures. This guide was written as a starting point, and it defers to the reader s set of rules if differences exist. The fuel cell industry is maturing, and project developers are gaining experience in working with federal agencies. Technology improvements, cost reductions, and experienced project developers are making fuel cell projects easier to put into service. In this environment, federal decision makers can focus on being smart buyers of fuel cell energy instead of attempting to become experts in fuel cell technology. For agencies that want to pursue a fuel cell CHP this guide presents a four step process for a successful project. 1. Perform a preliminary screening of the energy needs energy costs and incentives. 2. Compare a detailed project plan. 3. Make a financing and contracting decision. 4. Execute the project plan including financing, installation, and operation. The simplest procurement method is designated funding for the outright purchase of the fuel cell CHP system, although this is usually not the most cost-effective option. This guide describes the following financing options: Power purchase agreement Energy savings performance contract Utility energy services contract Enhanced use lease Fuel cell CHP technology can help federal facility managers comply with agency objectives for reducing energy consumption and air pollution emissions. Fuel cells do not generate particulate pollutants, unburned hydrocarbons or the gases that produce acid rain. Fuel cells emit less carbon dioxide (CO2) than other, less efficient technologies and use of renewable fuels can make them carbon neutral. Fuel cell CHP technology can deliver reliable electricity and heat with high efficiency (70% to 85%) in a small physical footprint with little noise, making it a cost-effective option for federal facilities.

PCS Nitrogen: Combustion Fan System Optimization Improves Performance and Saves Energy at a Chemical Plant
This U.S. Department of Energy Industrial Technologies Program case study describes how, in 2003, PCS Nitrogen, Inc., improved the efficiency of the combustion fan on a boiler at the company's chemical fertilizer plant in Augusta, Georgia. The project saved $420,000 and 76,400 million British thermal units (MBtu) per year. In addition, maintenance needs declined, because there is now less stress on the fan motor and bearings and less boiler feed water usage. This project was so successful that the company has implemented more efficiency improvements that should result in energy cost savings of nearly $1 million per year.

Fan to parallel beam conversion in CAT by rubber sheet transformation
A technique for converting fan-beam projections to parallel-beam projections for use in computed tomography is presented. The problem is approached by use of a rubber sheet transformation. Since the data is discretized, an interpolation step is necessary. For densely sampled data this approach appears satisfactory and a significant reduction in photon noise is observable in computer simulations.

Experimental Modal Analysis on a Rotating Fan Using Tracking-CSLDV
Continuous Scan Laser Doppler Vibrometry (CSLDV) modifies the traditional mode of operation of a vibrometer by sweeping the laser measurement point continuously over the structure while measuring, enabling one to measure spatially detailed mode shapes quickly and minimizing the inconsistencies that can arise if the structure or test conditions change with time. When a periodic scan path is employed, one can decompose the measurement into the response that would have been measured at each point traversed by the laser and obtain the structure's mode shapes and natural frequencies using conventional modal analysis software. In this paper, continuous-scan vibrometry is performed on a rotating fan, using computer controlled mirrors to track the rotating fan blades while simultaneously sweeping the measurement point over the blades. This has the potential to circumvent the difficulty of attaching contact sensors such as strain gauges, which might modify the structure and invalidate the results. In this work, impact excitation was used to excite a 3-blade fan rotating at various speeds, and the blades were scanned with a cloverleaf pattern that captured the bending of all three blades simultaneously. Some specialized signal processing is helpful in minimizing the effect of rotation frequency harmonics in the measurements, and specific scan strategies are needed to avoid those frequencies, both of these issues are discussed in the paper. While noise in the laser vibrometer does pose some difficulty, the results show that several modes could be extracted and that the tracking-CSLDV results agree with measurements obtained from the parked fan.

Communication with U.S. federal decision makers : a primer with notes on the use of computer models as a means of communication.
This document outlines ways to more effectively communicate with U.S. Federal decision makers by outlining the structure, authority, and motivations of various Federal groups, how to find the trusted advisors, and how to structure communication. All three branches of Federal governments have decision makers engaged in resolving major policy issues. The Legislative Branch (Congress) negotiates the authority and the resources that can be used by the Executive Branch. The Executive Branch has some latitude in implementation and prioritizing resources. The Judicial Branch resolves disputes. The goal of all decision makers is to choose and implement the option that best fits the needs and wants of the community. However, understanding the risk of technical, political and/or financial infeasibility and possible unintended consequences is extremely difficult. Primarily, decision makers are supported in their deliberations by trusted advisors who engage in the analysis of options as well as the day-to-day tasks associated with multi-party negotiations. In the best case, the trusted advisors use many sources of information to inform the process including the opinion of experts and if possible predictive analysis from which they can evaluate the projected consequences of their decisions. The paper covers the following: (1) Understanding Executive and Legislative decision makers - What can these decision makers do? (2) Finding the target audience - Who are the internal and external trusted advisors? (3) Packaging the message - How do we parse and integrate information, and how do we use computer simulation or models in policy communication?

HEPA Filter Differential Pressure Fan Interlock System Functional Requirements and Technical Design Criteria
Double-shell tanks (DSTs) and Double Contained Receiver Tanks (DCRTs) are actively ventilated, along with certain single-shell tanks (SSTs) and other RPP facilities. The exhaust air stream on a typical primary ventilation system is drawn through two stages of high-efficiency particulate air (HEPA) filtration to ensure confinement of airborne radioactive materials. Active ventilation exhaust stacks require a stack CAM interlock to detect releases from postulated accidents, and to shut down the exhaust fan when high radiation levels are detected in the stack airstream. The stack CAM interlock is credited as a mitigating control to stop continued unfiltered radiological and toxicological discharges from the stack, which may result from an accident involving failure of a HEPA filter. This document defines the initial technical design baseline for a HEPA filter AP fan interlock system.
Improving Control of a Dual-Duct Single-Fan Variable Air Volume Systems
This paper discusses improved control strategies for dual-duct single-fan variable air volume (VAV) systems. Common control strategy for supply air volume modulation is evaluated, and an improved air volume control strategy that maintains separate cold and hot air duct static pressure set points is presented. The paper also explores the interactions between the cold and hot deck temperatures and duct static pressures, and discusses the impact of non-ideal deck temperature settings on duct static pressures and overall system energy consumption. To compensate the negative impact of non-ideal cold and hot deck temperature set points, the authors propose using real-time duct static pressure readings as feedback signals to fine-tune the deck temperature set points. These new control schemes can reduce simultaneous cooling and heating while reducing fan power consumption.

Architectural characteristics of fine-grained submarine fans: A model applicable to the Gulf of Mexico
Submarine fan deposits in the Gulf of Mexico, modern and ancient, fall in the category of fine-grained, low overall sand/shale ratio basin-floor fans. Models published over the years that have been applied to both exploration and production are based on sand-rich fans, most of which were deposited in active margin settings. These models should not be used for the Gulf of Mexico or any other deep water system with similar basinal settings. Observations from the excellent outcrops of the Permian Tanqua Karoo in southwestern South Africa, together with information from the modern Mississippi Fan, and the Jackfork turbidites in Arkansas, enable the construction of a model that addresses the architecture of both the macro and meso-scale depositional features of fine-grained turbidite systems. At the entrance to the basin floor the conduit, carved out across the slope, may start to widen. Most of the density flows moving through do not necessarily occupy the conduit`s entire width. The result is a complex of laterally and vertically stacked channel fills and associated levee-overbank deposits with a good degree of connectivity. The channel fills are mostly massive, whereas the levee deposits are low-contrast, low-resistivity thin-bedded sandstones and shales with high permeability. Such sandstones can be potentially very productive. The channels gradually become smaller and as their influence on directing the heads of turbidity currents decreases, oblong sheet sands are deposited, each having a very large width to thickness ratio and a high sand/shale ratio. The vertical stacking patterns within these sheet sands commonly display lateral offset of individual beds or groups of beds, and therefore form a distinct reservoir type with varying internal fluid-flow characteristics.

Design, testing and two-dimensional flow modeling of a multiple-disk fan
A multiple-disk Tesla type fan has been designed, tested and analyzed two-dimensionally using the conservation of angular momentum principle. Experimental results showed that such multiple-disk fans exhibited exceptionally low performance characteristics, which could be attributed to the low viscosity, tangential nature of the flow, and large mechanical energy losses at both suction and discharge sections that are comparable to the total input power. By means of theoretical analysis, local and overall shearing stresses on the disk surfaces have been determined based on tangential and radial velocity distributions of the air flow of different volume flow rates at prescribed disk spaces and rotational speeds. Then the total power transmitted by rotating disks to air flow, and the power acquired by the air flow in the gap due to transfer of angular momentum have been obtained by numerically integrating shearing stresses over the disk surfaces. Using the measured shaft and hydraulic powers, these quantities were utilized to evaluate mechanical energy losses associated with the suction and discharge sections of the fan. (author)

Random fan-out state induced by site-random interlayer couplings
We study the low-temperature properties of a classical Heisenberg model with site-random interlayer couplings on the cubic lattice. This model is introduced as a simplified effective model of Sr(Fe{sub 1-x}Mn{sub x})O{sub 2}, which was recently synthesized. In this material, when x=0.3, ({pi}{pi}{pi}) and ({pi}{pi}0) mixed ordering is observed by neutron diffraction measurements. Using Monte Carlo simulations, we find an exotic bulk spin structure that explains the experimentally obtained results. We name this spin structure the ''random fan-out state.'' The mean-field calculations provide an intuitive understanding of this phase being induced by the site-random interlayer couplings. Since Rietveld analysis assuming the random fan-out state agrees well with the neutron diffraction pattern of Sr(Fe{sub 0.7}Mn{sub 0.3})O{sub 2}, we conclude that the random fan-out state is reasonable for the spin-ordering pattern of Sr(Fe{sub 0.7}Mn{sub 0.3})O{sub 2} at the low-temperature phase.

Standard practice for examination of fiberglass reinforced plastic fan blades using acoustic emission
1.1 This practice provides guidelines for acoustic emission (AE) examinations of fiberglass reinforced plastic (FRP) fan blades of the type used in industrial cooling towers and heat exchangers. 1.2 This practice uses simulated service loading to determine structural integrity. 1.3 This practice will detect sources of acoustic emission in areas of sensor coverage that are stressed during the course of the examination. 1.4 This practice applies to examinations of new and in-service fan blades. 1.5 This practice is limited to fan blades of FRP construction, with length (hub centerline to tip) of less than 3 m [10 ft], and with fiberglass content greater than 15 % by weight. 1.6 AE measurements are used to detect emission sources. Other nondestructive examination (NDE) methods may be used to evaluate the significance of AE sources. Procedures for other NDE methods are beyond the scope of this practice. 1.7 Units�The values stated in either SI units or inch-pound units are to be regarded separately as sta...

High-amplitude reflection packets (HARPs) of the Mississippi Fan, Gulf of Mexico
Examination of seismic data from the deep-water Gulf of Mexico reveals the presence of High-Amplitude Reflection Packets (HARPs). An analog study conducted by the Ocean Drilling Program Leg 155 identified and described Amazon Fan HARPs as a stacked, relatively unconfined series of graded turbidites overlain by a channel-levee. HARP seismic facies thin laterally and onlap antecedent bathymetry (preexisting submarine topography). HARP areal extent is controlled by antecedent bathymetry and turbidity flow sediment volumes. Mississippi Fan HARP deposition can be described by three depositional models: the "avulsion" model, the "fill and spill" model, and the "transition" model. The "avulsion" depositional model, developed by Flood et al. (1991), describes avulsion of submarine channel-levees by turbidity flows. Subsequent turbidity flows exit the channel-levee at the avulsion point and are deposited as unchannelized HARPs. The "fill and spill" model, developed by Satterfield and Behrens (1990), describes turbidite deposition in the Gulf of Mexico salt province. Initial stages of the "fill and spill" model accurately describe the seismic geometries of HARPs confined by adjacent salt structures. The "transition" model was developed in this study to describe the Gulf of Mexico HARP seismic geometries seen in the transition zone from the salt province to the abyssal plain. The HARPs described by the "transition" model contain an upslope segment confined by salt structures and a downslope segment confined by antecedent bathymetry. Utilizing seismic data from the Gulf of Mexico and core and well-log data from the Amazon Fan, this study has determined that HARPs and related channel-levees have hydrocarbon play potential. HARP sheet sands, internal HARP channel fill, overlying channel-levee fill, and overbank levee sands are potential reservoir units. Detrital carbonate and hemipelagic shale source rocks are in place in the deep-water Gulf of Mexico. In addition, structurally derived migration pathways combine with percolation as potential migration processes. This study integrates identification and description of HARP seismic facies relationships, current and newly developed depositional models, interpretation of stratigraphic controls, HARP internal reservoir architecture, and determination of HARP hydrocarbon potential in order to predict HARP deposition in the Mississippi Fan and other mud-rich fans worldwide.

Economic Recovery of Oil Trapped at Fan Margins Using Hig Angle Wells Multiple Hydraulic Fractures
The Yowlumne field is a giant field in the southern San Joaquin basin, Kern County, California. It is a deep (13,000 ft) waterflood operation that produces from the Miocene- aged Stevens Sand. The reservoir is interpreted as a layered, fan-shaped, prograding turbidite complex containing several lobe-shaped sand bodies that represent distinct flow units. A high ultimate recovery factor is expected, yet significant quantities of undrained oil remain at the fan margins. The fan margins are not economic to develop using vertical wells because of thinning pay, deteriorating rock quality, and depth. This project attempts to demonstrate the effectiveness of exploiting the northeast distal fan margin through the use of a high- angle well completed with multiple hydraulic- fracture treatments. A high-angle well offers greater pay exposure than can be achieved with a vertical well. Hydraulic-fracture treatments will establish vertical communication between thin interbedded layers and the wellbore. The equivalent production rate and reserves of three vertical wells are anticipated at a cost of approximately two vertical wells. The near-horizontal well penetrated the Yowlumne sand; a Stevens sand equivalent, in the distal fan margin in the northeast area of the field. The well was drilled in a predominately westerly direction towards the interior of the field, in the direction of improving rock quality. Drilling and completion operations proved to be very challenging, leading to a number of adjustments to original plans. Hole conditions resulted in obtaining less core material than desired and setting intermediate casing 1200 ft too high. The 7 in. production liner stuck 1000 ft off bottom, requiring a 5 in. liner to be run the rest of the way. The cement job on the 5 in. liner resulted in a very poor bond, which precluded one of three hydraulic fracture treatments originally planned for the well. Openhole logs confirmed most expectations going into the project about basic rock properties: the formation was shaly with low porosities, and water saturations were in line with expectations, including the presence of some intervals swept out by the waterflood. High water saturations at the bottom of the well eliminated one of the originally planned hydraulic fracture treatments. Although porosities proved to be low, they were more uniform across the formation than expected. Permeabilities of the various intervals continue to be evaluated, but appear to be better than expected from the porosity log model derived in Budget Period One. The well was perforated in all pay sections behind the 5 in. liner. Production rates and phases agree nicely with log calculations, fractional flow calculations, and an analytical technique used to predict the rate performance of the well.

Busemann functions and the speed of a second class particle in the rarefaction fan
In this paper we will show how the results found in Cator and Pimentel 2009, about the Busemann functions in last-passage percolation, can be used to calculate the asymptotic distribution of the speed of a single second class particle starting from an arbitrary deterministic configuration which has a rarefaction fan, in either the totally asymetric exclusion process, or the Hammersley interacting particle process. The method will be to use the well known last-passage percolation description of the exclusion process and of the Hammersley process, and then the well known connection between second class particles and competition interfaces.

Strategy for the Operation of Cooling Towers with variable Speed Fans
Within the SPS Cooling Water Project at CERN aimed at the reduction of water consumption, this primary open cooling loop will be closed and all the primary cooling circuit components will be upgraded to the new required duty and brought to the necessary safety and operability standards. In particular the tower fans will be fitted with variable frequency drives to replace the existing two speed motors. This paper presents a study to optimize the operation of SPS cooling towers taking into account outdoor conditions (wet and dry bulb temperatures) and the entirety of the primary circuit in which they will operate.

Correlation efficiency as a tool to establish depositional subenvironments in submarine fans
Depositional units in submarine fan systems commonly are too large to be entirely or sufficiently exposed in an outcrop to properly identify. Channel fills can be massive, bedded, or any combination thereof. The layering can be horizontal or inclined. Typical bedded series can be thick or thin bedded, or a combination with or without a certain cyclicity. Occurrence of sedimentary structures is not yet a decisive interpretation characteristic. At the present, the Lower Permian Skoorsteenberg Formation of the Southwest Karoo in South Africa may be the best example of long, nontilted, outcrops where entire subenvironments can be observed. Using that knowledge, outcrop information from several areas, and ideas from the literature, we attempted correlations in two spillways in the Jackfork Group in Arkansas. A layer-by-layer correlation failed, even after small layer package could be established using an occasional thick shale break, a major slump, or a very thick massive sandstone layer for dividing both sides of the spillway. A [open quotes]semi-logarithmic[close quotes] display of measured thickness provides patterns of variations in layer thickness that normally are sufficiently typical to use as a correlation tool between both sides. This is not a foolproof system and one should consider additional parameters, such as location within the entire fan system. However, the degree of correlatibility helps identify or suggest depositional environments.

Influence of provenance on detrital and diagenetic mineralogy of small tertiary fans in southwestern Montana
In the North Boulder River basin in southwestern Montana, alluvial fans of the Renova (Oligocene-Miocene) and the Sixmile Creek (Miocene) Formations were deposited on the flanks of north-south-trending uplifts that also supplied the detritus. The Elkhorn Mountain volcanics (78 m.y.) overlying the Boulder batholith make up the western highlands, a small patch of Precambrian Belt Group rocks occur in the southwest and Paleozoic siliciclastic and carbonate rocks forming the eastern margin. The fan sediments thus allow adequate control for studying the influence of source rocks on detrital and diagenetic mineralogy. Modal analysis of 6228 grains in 31 thin sections shows a decrease of VRF away from the igneous sources (37% to 1% in a north-south transect; 37% to 7% in a west-east transect) along with an increase in quartz (8% to 24% and 3% to 13%) and plagioclase (2% to 16% and 2% to 10%); orthoclase abundance is low except in the southwest. Volcanic ash and glass shards are found in the younger sediments in the northern part of the basin. Their data show a positive correlation between the abundance of orthoclase and kaolinite (north-south transect); between SRF and carbonate cement (west-east transect) and between glass shards and smectite (both north-south and west-east transects). They infer that the diagenetic mineralogy of these sands was controlled essentially by the detrital particles, which were strongly controlled by source rocks in this area.

as sizing a fan to deliver the design ventilation rate (fans and natural infiltration, in order to properly designfans should be as small as necessary to deliver the effective design
The velocity pattern of a fan loop structure within a solar active region over the temperature range 0.15-1.5 MK is derived using data from the EUV Imaging Spectrometer (EIS) on board the Hinode satellite. The loop is aligned toward the observer's line of sight and shows downflows (redshifts) of around 15 km s{sup -1} up to a temperature of 0.8 MK, but for temperatures of 1.0 MK and above the measured velocity shifts are consistent with no net flow. This velocity result applies over a projected spatial distance of 9 Mm and demonstrates that the cooler, redshifted plasma is physically disconnected from the hotter, stationary plasma. A scenario in which the fan loops consist of at least two groups of 'strands'-one cooler and downflowing, the other hotter and stationary-is suggested. The cooler strands may represent a later evolutionary stage of the hotter strands. A density diagnostic of Mg VII was used to show that the electron density at around 0.8 MK falls from 3.2 Multiplication-Sign 10{sup 9} cm{sup -3} at the loop base, to 5.0 Multiplication-Sign 10{sup 8} cm{sup -3} at a projected height of 15 Mm. A filling factor of 0.2 is found at temperatures close to the formation temperature of Mg VII (0.8 MK), confirming that the cooler, downflowing plasma occupies only a fraction of the apparent loop volume. The fan loop is rooted within a so-called outflow region that displays low intensity and blueshifts of up to 25 km s{sup -1} in Fe XII {lambda}195.12 (formed at 1.5 MK), in contrast to the loop's redshifts of 15 km s{sup -1} at 0.8 MK. A new technique for obtaining an absolute wavelength calibration for the EIS instrument is presented and an instrumental effect, possibly related to a distorted point-spread function, that affects velocity measurements is identified.

Optimized Fan Control In Variable Air Volume HVAC Systems Using Static Pressure Resets: Strategy Selection and Savings Analysis
The potential of static pressure reset (SPR) control to save fan energy in variable air volume HVAC systems has been well documented. Current research has focused on the creation of reset strategies depending on specific system features. As the commissioning process has begun to require the prediction of savings, knowledge of the extent to which various SPR control strategies impact fan energy has become increasingly important. This research aims to document existing SPR control strategies and utilize building data and simulation to estimate fan energy use. A comprehensive review of the literature pertaining to SPR control was performed and the results were organized into a top-down flow chart tool. Based on the type of feedback available from a particular system, or lack thereof, this tool will facilitate the selection of a SPR control strategy. A field experiment was conducted on a single duct variable air volume system with fixed discharge air temperature and static pressure setpoints. Finally, an air-side model of the experimental system was created using detailed building design information and calibrated using field measurements. This model was used to estimate the fan energy required to supply the trended airflow data using fixed static pressure (FSP) and SPR control based on zone demand, system demand, and outside air temperature. While utilizing trend data from November 1, 2008 to February 12, 2009, the FSP control of the experimental system was used as the baseline for ranking the energy savings potential of nine different forms of duct static pressure control. The highest savings (73-74%) were achieved using zonal demand based SPR control. System demand based SPR control yielded savings ranging from 59 to 76%, which increased when the duct sensor was positioned near the fan discharge and under similar zone load conditions. The outside air temperature based SPR control yielded savings of 65% since the experimental system supplied primarily perimeter zones. Finally, increasing the FSP setpoint from 2 to 3 inWG increased fan energy by 45%, while decreasing the setpoint from 2 to 1 inWG decreased fan energy by 41%.

The paper discusses the benefits of having a consistent testing method to characterize aerodynamic and energy performance of FFUs. It presents evaluation methods of laboratory-measured performance of ten relatively new, 1220 mm x 610 mm (or 4 ft x 2 ft) fan-filter units (FFUs), and includes results of a set of relevant metrics such as energy performance indices (EPI) based upon the sample FFUs tested. This paper concludes that there are variations in FFUs' performance, and that using a consistent testing and evaluation method can generate compatible and comparable FFU performance information. The paper also suggests that benefits and opportunities exist for our method of testing FFU energy performance to be integrated in future recommended practices.
Sand-rich submarine fans, Mio-Pliocene of Santa Monica Basin, offshore California: Untapped exploration targets
Santa Monica Basin lies directly west of Los Angeles Basin, one of the world's most prolific oil provinces. Published literature suggests that Santa Monica Basin was starved of coarse clastics during the late Miocene through Pliocene. However, seismic sequence stratigraphy indicates that deposition of sand-rich fans alternated with mixed-load systems throughout the Delmontian and Repettian stages. Seismic sequences and facies are calibrated to seismic and well data from Beta Oil Field, in San Pedro Basin to the south. Eustasy evidently played a dominant role in controlling sedimentation. Variations in tan lithology, thickness, and basinward extent correspond to worldwide changes in sea level. Regional erosion surfaces apparently signify drops in sea level. Overlying thick seismic packages display hummocky to chaotic seismic facies separated by high- to low-amplitude continuous reflections. These configurations are interpreted as inner- to mid-fan channels separated by overbank deposits in sand-rich lowstand fans. High-amplitude basinwide reflections bound the tops of the sand-rich intervals, and likely represent condensed sections formed during sea-level rises. Thin seismic intervals above the condensed sections display downlap, and are interpreted as interbedded sandstones and shales of prograding highstand fans. Sediment input to Santa Monica Basin, based on seismic-facies and isochron patterns, was predominantly from the (present-day) north, with subordinate input from the east. High-amplitude eustatic variations dominated deposition and sequence development even in this tectonically active basin Previously unidentified sand-rich fans are present, and have not been drilled.

An automated fault detection and diagnosis tool for HVAC systems is being developed, based on an integrated, life-cycle, approach to commissioning and performance monitoring. The tool uses component-level HVAC equipment models implemented in the SPARK equation-based simulation environment. The models are configured using design information and component manufacturers' data and then fine-tuned to match the actual performance of the equipment by using data measured during functional tests of the sort using in commissioning. This paper presents the results of field tests of mixing box and VAV fan system models in an experimental facility and a commercial office building. The models were found to be capable of representing the performance of correctly operating mixing box and VAV fan systems and detecting several types of incorrect operation.
Performance Optimization of a Fan System- Overcoming Impacts of Modified Design Criteria Due to Regulatory Requirements and Changed Operating Conditions
The Louisiana Pacific mill in Tomahawk Wisconsin manufactures oriented-strand board. Several large induced-draft fans and combustion-air blowers were operating inefficiently at this mill. This case study highlights a systems approach that was applied to address fan inefficiency. Energy savings from optimizing the system are estimated to be 338 kW, nearly half of the original measured input power of 678 kW. The project is currently being implemented and will have a payback period of less than 8 months. The opportunities here are typical of opportunities thought to exist in most industrial plants. In this case, process needs changed due to environmental regulations and change of location, but the system did not, leading to low overall system efficiency.

Ultrabroadband optical parametric chirped-pulse amplifier using a fan-out periodically poled crystal with spectral spatial dispersion
Based on the full two-dimensional characteristics of the quasi-phase-matched fan-out periodically poled crystal, a scalable and engineerable scheme for ultrabroadband optical parametric chirped-pulse amplification is proposed, which can significantly broaden the gain bandwidth by the spatial separation of different frequency components of the signal pulse and manipulation of the distribution of the pump beam along the fan-out direction of the crystal. The theoretical analysis shows that the signal pulse can be amplified with minimal spectrum narrowing, and the initial spectrum can be broadened considerably if needed. Based on this scheme, using a fan-out periodically poled 5% mol MgO-doped congruent lithium niobate with a configuration of 5x0.5x5 mm{sup 3} and two pump beams, the 3.3-{mu}m middle-infrared ultrabroadband optical parametric chirped-pulse amplifier is designed. The numerical computation results confirm that the -3 dB gain bandwidth of this amplifier exceeds 320 nm and can be further broadened.

Impacts of Static Pressure Reset on VAV System Air Leakage, Fan Power and Thermal Energy - Part I: Theoretical Model and Simulation
As for a variable air volume (VAV) system, the air duct static pressure is a typical control variable maintained by modulating supply fan speed. The static pressure equals to the summation of the duct pressure loss downstream of the sensor to the terminal box and box inlet static pressure. Typically, the air duct static pressure is set as a constant set point based on the system design information and sensor location. However, under partial load conditions, the terminal box dampers have to be closed more since either required airflow is less than the design airflow which directly leads to much less pressure loss. Thus the static pressure set point should be reset lower in order to reduce fan power, avoid noise at terminal box dampers and box damper malfunction due to excessive pressure. Different static pressure reset schedules are reviewed and compared, considering the influence of outside air temperature on the building load, availability of the VAV box damper positions, the airflow ratio based static pressure reset has also applicable advantages over the existing constant static pressure set point and two typical reset methods. This paper present the theoretical models to express the impacts of static pressure reset on fan airflow, fan head, air leakage, fan power and thermal energy for both pressure independent and pressure dependent boxes. The impacts are also demonstrated using the parametric analysis and numerical results to show the benefits of the static pressure reset including reducing fan power, cooling energy and heating energy.

Economic Recovery of Oil Trapped at Fan Margins Using High Angle Wells Multiple Hydraulic Fractures
This project attempts to demonstrate the effectiveness of exploiting thin-layered, low-energy deposits at the distal margin of a prograding turbidite complex through the use of hydraulically fractured horizontal or high-angle wells. The combination of a horizontal or high-angle well and hydraulic fracturing will allow greater pay exposure than can be achieved with conventional vertical wells while maintaining vertical communication between thin interbedded layers and the wellbore. A high-angle well will be drilled in the fan-margin portion of a slope-basin clastic reservoir and will be completed with multiple hydraulic-fracture treatments. Geologic modeling, reservoir characterization, and fine-grid reservoir simulation will be used to select the well location and orientation. Design parameters for the hydraulic-fracture treatments will be determined, in part, by fracturing an existing test well. Fracture azimuth will be predicted by passive seismic monitoring of a fracture-stimulation treatment in the test well using logging tools in an offset well.

Adaptive planning using megavoltage fan-beam CT for radiation therapy with testicular shielding
This study highlights the use of adaptive planning to accommodate testicular shielding in helical tomotherapy for malignancies of the proximal thigh. Two cases of young men with large soft tissue sarcomas of the proximal thigh are presented. After multidisciplinary evaluation, preoperative radiation therapy was recommended. Both patients were referred for sperm banking and lead shields were used to minimize testicular dose during radiation therapy. To minimize imaging artifacts, kilovoltage CT (kVCT) treatment planning was conducted without shielding. Generous hypothetical contours were generated on each 'planning scan' to estimate the location of the lead shield and generate a directionally blocked helical tomotherapy plan. To ensure the accuracy of each plan, megavoltage fan-beam CT (MVCT) scans were obtained at the first treatment and adaptive planning was performed to account for lead shield placement. Two important regions of interest in these cases were femurs and femoral heads. During adaptive planning for the first patient, it was observed that the virtual lead shield contour on kVCT planning images was significantly larger than the actual lead shield used for treatment. However, for the second patient, it was noted that the size of the virtual lead shield contoured on the kVCT image was significantly smaller than the actual shield size. Thus, new adaptive plans based on MVCT images were generated and used for treatment. The planning target volume was underdosed up to 2% and had higher maximum doses without adaptive planning. In conclusion, the treatment of the upper thigh, particularly in young men, presents several clinical challenges, including preservation of gonadal function. In such circumstances, adaptive planning using MVCT can ensure accurate dose delivery even in the presence of high-density testicular shields.

Fracture azimuth will be predicted by passive seismic monitoring of a fracture-stimulation treatment in the test well using logging tools in an offset well. The long radius, near horizontal well was drilled during the first quarter of 1996. Well conditions resulted in the 7 in. production liner sticking approximately 900 ft off bottom. Therefore, a 5 in. production liner was necessary to case this portion of the target formation. Swept-out sand intervals and a poor cement bond behind the 5 in. liner precluded two of the three originally planned hydraulic fracture treatments. As a result, all pay intervals behind the 5 in. liner were perforated and stimulated with a non-acid reactive fluid. Following a short production period, the remaining pay intervals in the well (behind the 7 in. liner) were perforated. The well was returned to production to observe production trends and pressure behavior and assess the need to stimulate the new perforations.
Comparing Two Types of Magnetically- Coupled Adjustable Speed Drives with Variable Frequency Drives in Pump and Fan Applications
This paper presents the results from laboratory tests on MagnaDrive Corporations fixed-magnet magnetically-coupled adjustable speed drive (MC-ASD) and Coyote Electronics electromagnetic MC-ASD as compared to a typical variable frequency drive (VFD) for typical fan and pump loads. It also discusses advantages and disadvantages of using mechanical MC-ASD versus VFDs and it provides field experience with VFDs in refrigerated warehouses as well as the fixed magnet MC-ASD in wastewater and other field applications. Laboratory tests for a 50 hp fan retrofit showed electronic VFD savings at 62%, the MagnaDrive Coupling at 39% and PAYBACK Drive at 46%. At $0.06/kWh and list prices, the simple payback for the VFD is 2.4 years, the MagnaDrive is 4.6 years and the PAYBACK is 1.9 years. MagnaDrive has models from 25 to 500 hp while PAYBACK has models from 3 to 200 hp. Contractors to the Northwest Energy Efficiency Alliance have helped to install VFDs for about 300 evaporator fans in over two dozen refrigerated warehouses and to install fixed-magnet MC-ASDs in about 50 applications with about half of these controlling wastewater pumps. The Alliance has no particular field experience with the electcromagnetic coupling. The primary advantages of magnetically coupled adjustable speed drives (MC-ASD) over VFDs come from reduced maintenance, resistance to dirty environments, separation of load vibration from the motor, and less stringent requirements for precise shaft alignment. Field experience indicates reductions in noise and repairs from vibration loads, tolerance of poor electrical power quality, and ease of installation are often more important than energy savings. The MC-ASDs are being used where VFDs have not survived or are considered too complicated.

Impacts of Static Pressure Reset on VAV System Air Leakage, Fan Power and Thermal Energy - Part 2: Case Demonstration for a Typical Climate System
In Part 1 of this paper, the theoretical models, integrating the fan airflow, fan head, air leakage factors, are developed to analyze the impacts of the static pressure reset on both pressure dependent and pressure independent terminal boxes. In this part, a simulated air handling unit (AHU) system in Omaha NE is used to demonstrate the energy savings performance in one typical climate year. This AHU system has a static pressure reset system and two constant static pressure systems, one having pressure dependent terminal boxes and one having pressure independent terminal boxes. These simulated systems were compared mainly on the basis of fan power energy consumption and thermal energy consumption in totally a year. The example presents a good agreement with the theoretical model and simulation results. It was also shown that static pressure reset provides a promising and challenging way for the energy performance in VAV system.

Reserve growth through geological characterization of heterogeneous reservoirs - an example from mud-rich submarine fan reservoirs of Permian Spraberry Trend, west Texas
Tight, naturally fractured Permian submarine fan reservoirs in the Midland basin contained more than 10.5 billion bbl of oil at discovery. Ultimate recovery is estimated to average 7% of the original oil in place. At abandonment 4 billion bbl of nonresidual mobile oil will remain in untapped or poorly drained reservoir compartments. This unproduced mobile oil is the target for Spraberry reserve growth through strategic infill drilling. Mid-fan facies of three separate submarine fans are productive in the Shackelford and Preston waterflood units (SPWU) in the central Spraberry Trend. Braided to meandering paleodip-oriented channels are flanked by levees which grade into upward-coarsening, unconfined distal fan sediment. Facies boundaries compartmentalize the reservoir, providing for interwell, stratigraphic entrapment of oil. Field-wide heterogeneity is pronounced. Stacking of channels in the upper Spraberry in the eastern half of the SPWU results in a dip-oriented belt of better reservoir quality. Wells completed in this axis have produced two to six times the amount of oil produced from wells located off of the depo-axis. Although fractures are important in early production, the contribution of matrix porosity is critical throughout the life of the reservoir. Current economics dictate that reserve growth might best be attained by siting new strategic infill wells in depositional axes and by selective recompletions of existing wells in areas of poorer reservoir quality for bypassed oil in undrained reservoir compartments.

Structure function of the nucleus in the perturbative QCD with $N_c\\to\\infty$ (BFKL pomeron fan diagrams)
Equation for the sum of BFKL pomeron fan diagrams is rederived by direct summation and solved numerically for rapidities $y\\leq 50$. At high rapidities y>20 the resulting cross-sections for the scattering of a longitudinally polarized $q\\bar q$ pair on the nucleus cease to depend on its transverse dimension and tend to a constant limit 0.1768 $R_A^2$, which corresponds to scattering of a colour dipole on a black disk. Thus the unitarity is restored and the singularity in the j plane is reduced to a simple pole at j=1.The nuclear structure function at small x behaves as $Q^2\\ln(1/x)$. The found gluon density has a soliton-like form in the $\\log k$ space: its form is close to Gaussian, independent of rapidity, the centermoving towards higher $\\log k$ with a nearly constant velocity as rapidity increases.

TF30 third-stage composite fan blade service program. Final technical report 1 Jul 1970--31 Dec 1977. [BORSIC/aluminum
The successful application of advanced composites as the structural material for aircraft jet engine rotating parts will significantly reduce engine weight and improve engine performance characteristics. To solve the component design, manufacturing, and quality assurance problems associated with such an application, a program was conducted to design and develop BORSIC/Aluminum third-stage fan blades, which would operate satisfactorily in the TF30-P-7 or P-9 engine models. Program objectives successfully were to improve the existing design of a composite material fan blade, manufacture the blade, and demonstrate its quality by bench and engine environment testing. The scope of the program required to meet these objectives included establishing design and fabrication procedures, developing special tooling, evaluating current nondestructive inspection techniques and adapting these techniques to composite materials, establishing quality assurance criteria, and developing comprehensive bench and engine environment test programs to adequately demonstrate fan-blade quality. During the program, several sets of BORSIC/Aluminum blades weighing 40 percent less than comparable TF30 bill of material titanium blades were successfully produced and tested. On the basis of extensive test program, and with the establishment of quality control criteria and repair procedures, the blades were deemed acceptable for evaluation in a flight program. During the total program, 246 engine-configuration blades were manufactured and non-destructively inspected; with an overall acceptance rate of 92.3%.

Efficiency of a liquid desiccant dehumidification system regenerated by using solar collectors/regenerators with photovoltaic fans
A hybrid solar dehumidification air-conditioning system was used to study the absorption of water vapor from moist air by contacting the air with aqueous solutions that contained from 90 to 94% triethylene glycol (TEG). For the packings of 2-inch polypropylene Jaeger Tri-Packs, which have a surface-to-volume ratio of 157 m{sup 2}/m{sup 3} (48 ft{sup 2}/ft{sup 3}), the efficiency of dehumidification can reach 93.3%. The environmental air was introduced into the dehumidifier cocurrently flowing with the liquid desiccant, and the liquid desiccant was sprayed on the top of the packing material. The air-to-liquid mass flow ratio was controlled in a range of 0.46 to 1.36. As the moisture was absorbed from air by the TEG solution, the solution was diluted. The regeneration of the solution was carried out in 20-piece (38.8 m{sup 2}) basin-type solar collectors/regenerators whose regeneration coefficients of performance are above 0.2. Air generated by photovoltaic fans was blown into the solar collectors/regenerators and carried away the water vapor from the evaporation of the aqueous desiccant solution. On the basis of the experimental results, the system performance is acceptable for most applications.

Development of a Laboratory Verified Single-Duct VAV System Model with Fan Powered Terminal Units Optimized Using Computational Fluid Dynamics
Single Duct Variable Air Volume (SDVAV) systems use series and parallel Fan Powered Terminal Units to control the air flow in conditioned spaces. This research developed a laboratory verified model of SDVAV systems that used series and parallel fan terminal units where the fan speeds were controlled by either Silicon Controlled Rectifiers (SCR) or Electronically Commutated Motors (ECM) motors. As part of the research, the model was used to compare the performance of the systems and to predict the harmonics generated by ECM systems. All research objectives were achieved. The CFD model, which was verified with laboratory measurements, showed the potential to identify opportunities for improvement in the design of the FPTU and accurately predicted the static pressure drop as air passed through the unit over the full operating range of the FPTU. Computational fluid dynamics (CFD) models of typical a FPTU were developed and used to investigate opportunities for optimizing the design of FPTUs. The CFD model identified key parameters required to conduct numerical simulations of FPTU and some of the internal components used to manufacture the units. One key internal component was a porous baffle used to enhance mixing when primary air and induced air entered the mixing chamber. The CFD analysis showed that a pressure-drop based on face velocity model could be used to accurately predict the performance of the FPTU. The SDVAV simulation results showed that parallel FPTUs used less energy overall than series systems that used SCR motors as long as primary air leakage was not considered. Simulation results also showed that series ECM FPTUs used about the same amount of energy, within 3 percent, of parallel FPTU even when leakage was not considered. A leakage rate of 10 percent was enough to reduce the performance of the parallel FPTU to the level of the series SCR system and the series ECM FPTUs outperformed the parallel FPTUs at all weather locations used in the study.

Study of the effects of ambient conditions upon the performance of fan powdered, infrared, natural gas burners. Quarterly technical progress report, January 1, 1996--March 31, 1996
The objective of this investigation is to characterize the operation of fan powered infrared burner (PER) at various gas compositions and ambient conditions and develop design guidelines for appliances containing PER burners for satisfactory performance. During this past quarter, a porous radiant burner testing facility consisting of a commercial deep-fat fryer, an FTIR based spectral radiance measurement system, a set of flue gas analysis components, and a fuel gas mixing station was constructed. The measurement capabilities of the system were tested using methane and the test results were found to be consistent with the literature. Various gas mixtures were tested. Results indicated that the stability limits of the burner and emissions vary with fuel gas composition and air/fuel ratio. However, the maximum radiant efficiency of the burner remained constant. Results obtained from this study can be useful to develop optimum design guidelines for PER burner manufacturers.

Economic recovery of oil trapped at fan margins using high angle wells and multiple hydraulic fractures. Quarterly report, July 1--September 30, 1997
This project attempts to demonstrate the effectiveness of exploiting thin-layered, low-energy deposits at the distal margin of a prograding turbidite complex through the use of hydraulically fractured horizontal or high-angle wells. The combination of a horizontal or high-angle well and hydraulic fracturing will allow greater pay exposure than can be achieved with conventional vertical wells while maintaining vertical communication between thin interbedded layers and the wellbore. A high-angle well will be drilled in the fan-margin portion of a slope-basin clastic reservoir and will be completed with multiple hydraulic-fracture treatments. Geologic modeling, reservoir characterization, and fine-grid reservoir simulation will be used to select the well location and orientation. Design parameters for the hydraulic-fracture treatments will be determined, in part, by fracturing an existing test well. Fracture azimuth will be predicted by passive seismic monitoring of a fracture-stimulation treatment in the test well using logging tools in an offset well. The long radius, near horizontal well has been drilled. After pumping a remedial cement squeeze, all pay behind the 5 in. liner was perforated and stimulated. Once wellwork is complete for the existing perforations, a hydraulic fracture treatment will be pumped through a short interval of clustered perforations in the 7 in. liner. Following this frac, all pay behind the 7 in. liner will be perforated and completion operations will be final.

Variations in erosion and deposition for the last fifty years (based on estimates from 137Cs profiles) on surfaces (Late Pleistocene to Late Holocene in age) making up the Fortymile Wash alluvial fan south of Yucca Mountain, is a function of surface age and of desert pavement development or absence. For purposes of comparing erosion and deposition, the surfaces can be examined as three groups: (1) Late Pleistocene surfaces possess areas of desert pavement development with thin Av or sandy A horizons, formed by the trapping capabilities of the pavements. These zones of deposition are complemented by coppice dune formation on similar parts of the surface. Areas on the surface where no pavement development has occurred are erosional in nature with 0.0 +/- 0.0 cm to 1.5 +/- 0.5 cm of erosion occurring primarily by winds blowing across the surface. Overall these surfaces may show either a small net depositional gain or small erosional loss. (2) Early Holocene surfaces have no well-developed desert pavements, but may have residual gravel deposits in small areas on the surfaces. These surfaces show the most consistent erosional surface areas on which it ranges from 1.0 +/-.01 cm to 2.0+/- .01 cm. Fewer depositional forms are found on this age of surface so there is probably a net loss of 1.5 cm across these surfaces. (3) The Late Holocene surfaces show the greatest variability in erosion and deposition. Overbank deposition during floods cover many edges of these surfaces and coppice dune formation also creates depositional features. Erosion rates are highly variable and range from 0.0 +/- 0.0 to a maximum of 2.0+/-.01. Erosion occurs because of the lack of protection of the surface. However, the common areas of deposition probably result in the surface having a small net depositional gain across these surfaces. Thus, the interchannel surfaces of the Fortymile Wash fan show a variety of erosional styles as well as areas of deposition. The fan, therefore, is a dynamic system that primarily responds to the incising of the channels into the upper fan surface, and the development of protecting desert pavements with time.

By direct numerical calculations the influence of a physically relevant infrared cutoff and running coupling on the gluon density and structure function of a large nucleus is studied in the perturbative QCD approach. It is found that the infrared cutoff changes the solutions very little. Running of the coupling produces a bigger change, considerably lowering both the saturation momentum and values of the structure functions.

MADmap: A Massively Parallel Maximum-Likelihood Cosmic Microwave Background Map-Maker
MADmap is a software application used to produce maximum-likelihood images of the sky from time-ordered data which include correlated noise, such as those gathered by Cosmic Microwave Background (CMB) experiments. It works efficiently on platforms ranging from small workstations to the most massively parallel supercomputers. Map-making is a critical step in the analysis of all CMB data sets, and the maximum-likelihood approach is the most accurate and widely applicable algorithm; however, it is a computationally challenging task. This challenge will only increase with the next generation of ground-based, balloon-borne and satellite CMB polarization experiments. The faintness of the B-mode signal that these experiments seek to measure requires them to gather enormous data sets. MADmap is already being run on up to O(1011) time samples, O(108) pixels and O(104) cores, with ongoing work to scale to the next generation of data sets and supercomputers. We describe MADmap's algorithm based around a preconditioned conjugate gradient solver, fast Fourier transforms and sparse matrix operations. We highlight MADmap's ability to address problems typically encountered in the analysis of realistic CMB data sets and describe its application to simulations of the Planck and EBEX experiments. The massively parallel and distributed implementation is detailed and scaling complexities are given for the resources required. MADmap is capable of analysing the largest data sets now being collected on computing resources currently available, and we argue that, given Moore's Law, MADmap will be capable of reducing the most massive projected data sets.

Laboratory Information Management Systems for Forensic Laboratories: A White Paper for Directors and Decision Makers
Modern, forensics laboratories need Laboratory Information Management Systems (LIMS) implementations that allow the lab to track evidentiary items through their examination lifecycle and also serve all pertinent laboratory personnel. The research presented here presents LIMS core requirements as viewed by respondents serving in different forensic laboratory capacities as well as different forensic laboratory environments. A product-development methodology was employed to evaluate the relative value of the key features that constitute a LIMS, in order to develop a set of relative values for these features and the specifics of their implementation. In addition to the results of the product development analysis, this paper also provides an extensive review of LIMS and provides an overview of the preparation and planning process for the successful upgrade or implementation of a LIMS. Analysis of the data indicate that the relative value of LIMS components are viewed differently depending upon respondents' job roles (i.e., evidence technicians, scientists, and lab management), as well as by laboratory size. Specifically, the data show that: (1) Evidence technicians place the most value on chain of evidence capabilities and on chain of custody tracking; (2) Scientists generally place greatest value on report writing and generation, and on tracking daughter evidence that develops during their analyses; (3) Lab. Managers place the greatest value on chain of custody, daughter evidence, and not surprisingly, management reporting capabilities; and (4) Lab size affects LIMS preference in that, while all labs place daughter evidence tracking, chain of custody, and management and analyst report generation as their top three priorities, the order of this prioritization is size dependent.

Heterogeneous deep-sea fan reservoirs, Shackelford and Preston waterflood units, Spraberry Trend, West Texas
This book discusses the geological characterization of reservoir and production attributes of the Shackelford and Preston waterflood units, southeastern Midland County, West Texas. These two units, which are operated by Mobil Producing Texas and New Mexico, are part of the Permian Spraberry Trend. Conventional reserves in the Spraberry are estimated to be almost 60 million barrels of oil, and more than 4 billion barrels of unproduced mobile oil remain, making the Spraberry a prime target for extended conventional recovery from untapped or poorly drained reservoir compartments. The authors determine the stratigraphy of the formation, map sand distribution trends, and determine from cores and logs the extent and composition of facies that compose the principal reservoir units.

Investigation of Micro Porosity Sintered wick in Vapor Chamber for Fan Less Design
Micro Porosity Sintered wick is made from metal injection molding processes, which provides a wick density with micro scale. It can keep more than 53 % working fluid inside the wick structure, and presents good pumping ability on working fluid transmission by fine infiltrated effect. Capillary pumping ability is the important factor in heat pipe design, and those general applications on wick structure are manufactured with groove type or screen type. Gravity affects capillary of these two types more than a sintered wick structure does, and mass heat transfer through vaporized working fluid determines the thermal performance of a vapor chamber. First of all, high density of porous wick supports high transmission ability of working fluid. The wick porosity is sintered in micro scale, which limits the bubble size while working fluid vaporizing on vapor section. Maximum heat transfer capacity increases dramatically as thermal resistance of wick decreases. This study on permeability design of wick structure is 0.5 - 0.7, especially permeability (R) = 0.5 can have the best performance, and its heat conductivity is 20 times to a heat pipe with diameter (Phi) = 10mm. Test data of this vapor chamber shows thermal performance increases over 33 %.

The sedimentological and geotechnical characteristics of the lower continental slope and rise of the Mississippi Fan fold belt
The study is based on geological and geotechnical laboratory testing data of 70 three inch diameter piston cores. Concentration is along the Sigsbee Escarpment in a grid area between 90? and 91?W and 26.7? and 27.3?N. Water depth ranges from 1,200 meters below sea level to 2,500 meters below sea level. All data were used to characterize the seafloor processes that deposited these sediments. The Sigsbee Escarpment represents a complex topographic and geologic feature involving faults, slumps and steep slopes. Most of the study area is covered by hemipelagic Holocene sediments in 0.05 to 2.9 m thickness, greatest thickness being in bathymetric lows indicating that Holocene sediments are eroded at the bathymetric highs and transported down the slope. The underlying Pleistocene sediments are mostly laminated clays in the southwestern part of the study area, indicating no mass wasting. Hemipelagic sedimentation in quiet sea bottom environment was dominant throughout the accumulation of the unit. Several generations of slumps have occurred in the northeastern part of the Sigsbee Escarpment during the Pleistocene showing that this part of the study area is an area where active mass wasting and down slope processes dominate.

Final Project Report: Self-Correcting Controls for VAV System Faults Filter/Fan/Coil and VAV Box Sections
This report addresses original research by the Pacific Northwest National Laboratory for the California Institute for Energy and Environment on self-correcting controls for variable-air-volume (VAV) heating, ventilating and air-conditioning systems and focuses specifically on air handling and VAV box components of the air side of the system. A complete set of faults for these components was compiled and a fault mode analysis performed to understand the detectable symptoms of the faults and the chain of causation. A set of 26 algorithms was developed to facilitate the automatic correction of these faults in typical commercial VAV systems. These algorithms include training tests that are used during commissioning to develop models of normal system operation, passive diagnostics used to detect the symptoms of faults, proactive diagnostics used to diagnose the cause of a fault, and finally fault correction algorithms. Ten of the twenty six algorithms were implemented in a prototype software package that interfaces with a test bed facility at PNNL's Richland, WA, laboratory. Measurement bias faults were instigated in the supply-air temperature sensor and the supply-air flow meter to test the algorithms developed. The algorithms as implemented in the laboratory software correctly detected, diagnosed and corrected these faults. Finally, an economic and impact assessment was performed for the State of California for deployment of self-correcting controls. Assuming 15% HVAC energy savings and a modeled deployment profile, 3.1-5.8 TBu of energy savings are possible by year 15.

Secure Smart Environments: Security Requirements, Challenges and Experiences in Pervasive Computing
INTRODUCTION In an ideal pervasive computing environment, a large number of connected smart devices are deployed to collaboratively provision seamless services to users. Pervasive computing is enabled by various advanced technologies, particularly wireless technologies and the Internet. It has become a trend for our future lives. A pervasive computing environment can be extremely heterogeneous. We can imagine how many different devices are involved in a smart home: TVs, phones, cameras, coffee makers, or even books and bookshelves. Since these devices are smart and communicate with each other mainly via wireless links, security must be ensured. Otherwise, the smart devices deployed around us would come back to hunt us and the result would be catastrophic. In this abstract we briefly discuss some important security issues in pervasive computing. II.

The Separations Process Research Unit (SPRU) complex located on the Knolls Atomic Power Laboratory (KAPL) site in Niskayuna, New York, was constructed in the late 1940s to research the chemical separation of plutonium and uranium (Figure A-1). SPRU operated as a laboratory scale research facility between February 1950 and October 1953. The research activities ceased following the successful development of the reduction oxidation and plutonium/uranium extraction processes. The oxidation and extraction processes were subsequently developed for large scale use by the Hanford and Savannah River sites (aRc 2008a). Decommissioning of the SPRU facilities began in October 1953 and continued through the 1990s.
Correlation of turbulent burning velocities of ethanol-air, measured in a fan-stirred bomb up to 1.2 MPa
The turbulent burning velocity is defined by the mass rate of burning and this also requires that the associated flame surface area should be defined. Previous measurements of the radial distribution of the mean reaction progress variable in turbulent explosion flames provide a basis for definitions of such surface areas for turbulent burning velocities. These inter-relationships. in general, are different from those for burner flames. Burning velocities are presented for a spherical flame surface, at which the mass of unburned gas inside it is equal to the mass of burned gas outside it. These can readily be transformed to burning velocities based on other surfaces. The measurements of the turbulent burning velocities presented are the mean from five different explosions, all under the same conditions. These cover a wide range of equivalence ratios, pressures and rms turbulent velocities for ethanol-air mixtures. Two techniques are employed, one based on measurements of high speed schlieren images, the other on pressure transducer measurements. There is good agreement between turbulent burning velocities measured by the two techniques. All the measurement are generalised in plots of burning velocity normalised by the effective unburned gas rms velocity as a function of the Karlovitz stretch factor for different strain rate Markstein numbers. For a given value of this stretch factor a decrease in Markstein number increases the normalised burning velocity. Comparisons are made with the findings of other workers. (author)

Study of the effects of ambient conditions upon the performance of fan powered, infrared, natural gas burners. Quarterly report, April 1, 1996 - June 30, 1996
A porous radiant burner testing facility consisting of a commercial deep-fat fryer, an FTIR based spectral radiance measurement system, a set of flue gas analysis components, and a fuel gas mixing station was constructed. The measurement capabilities of the system were tested using methane and the test results were found to be consistent with the literature. Following the validation of the measurement system, various gas mixtures were tested to study the effect of gas compositions have on burner performance. Results indicated that the emissions vary with fuel gas composition and air/fuel ratio. The maximum radiant efficiency of the burner was obtained close to air/fuel ratio of 1.
