Navigating without vision: Basic and applied research
ABSTRACT: We describe some of the results of our program of basic and applied research on navigating without vision. One basic research topic that we have studied extensively is path integration, a form of navigation in which perceived self-motion is integrated over time to obtain an estimate of current posilion and orientation. In experiments on pathway completion, one test of path integration ability, we have found that subjects who are passively guided over the outbound path without vision exhibit significant errors when attempting to return to the origin but are nevertheless sensitive to turns and segment lengths in the stimulus path. We have also found no major differences in path inlegration ability among blirid and sighted populations. A model we havc developed that attributes errors in path integration to errors in encoding the stimulus path is a good beginning toward understanding path integration performance. In otber research on path integration, in which optic flow information was manipulated in addition to the proprioceptive and vestibular information of nonvisual locomotion, we havc found that optic flow is a weak input to the path integration process. In other basic research, our studies of auditory distance perception in outdoor environments show systematic underestimation oC sound source distance. Our applied research has been concerned with developing and evaluating a navigation system for the visually impaired that uses three recent technologies: the Global Positioning System, Geographic Information Systems, and virtual acouslics. Our work shows that there is considerable promise of these three technologies in allowing visually impaired individuals to navigate and learn about unfamiliar environments without the assistance of human guides.

Development of a Navigator and Imaging Techniques for the Cryogenic Dark Matter Search Detectors
This project contributes to the detection of flaws in the germanium detectors for the Cryogenic Dark Matter Search (CDMS) experiment. Specifically, after imaging the detector surface with a precise imaging and measuring device, they developed software to stitch the resulting images together, applying any necessary rotations, offsets, and averaging, to produce a smooth image of the whole detector that can be used to detect flaws on the surface of the detector. These images were also tiled appropriately for the Google Maps API to use as a navigation tool, allowing viewers to smoothly zoom and pan across the detector surface. Automated defect identification can now be implemented, increasing the scalability of the germanium detector fabrication.

XHTML Basic
The XHTML Basic document type includes the minimal set of modules required to be an XHTML host language document type, and in addition it includes images, forms, basic tables, and object support. It is designed for Web clients that do not support the full set of XHTML features; for example, Web clients such as mobile phones, PDAs, pagers, and settop boxes. The document type is rich enough for content authoring. XHTML Basic is designed as a common base that may be extended. For example, an event module that is more generic than the traditional HTML 4 event system could be added or it could be extended by additional modules from XHTML Modularization such as the Scripting Module. The goal of XHTML Basic is to serve as a common language supported by various kinds of user agents. The document type definition is implemented using XHTML modules as defined in "Modularization of XHTML" [XHTMLMOD [p.9] ]. 19 Dec 2000 08:40 1 XHTML Basic Status of this Document This section describes the status of this document at the time of its publication.

Navigation drilling technology progresses
SciTech Connect
This article reports that navigation drilling - an approach that combines advanced drill bit, downhole motor, measurement-while-drilling, and well planning technology into an integrated, steerable drilling system - has reduced drilling time for operating companies worldwide. A major operating advantage of navigation drilling is the ability to drill both straight and directional intervals with a single assembly. In conventional directional drilling, a bent sub and downhole motor (or a bent housing motor) are used to initiate kick-offs and make course corrections. The bent sub is made-up above the motor, tilting the motor's axis 1 to 3 degrees compared to the axis of the drill string. The assembly toolface can be aligned in the desired direction with a single-shot, a steering tool or an MWD system.

Basic Bacteria
Basic Bacteria Basic Bacteria Name: Valerie Location: N/A Country: N/A Date: N/A Question: I'm doing a science project on bacteria. WHat I'm doing is washing forks with different dishwashing liquids, then wiping any remaining bacteria on to Agar petri dishes. Then incubating it and seeing which soap removed the most. My question is what kind of bacteria would be growing? and also do I just count the colonies to compare? and how long and at what temperature should I incubate this bacteria? Thank you very much for your time. I'll be looking forward to your response. Replies: The temperature is easy: 37 degrees C is optimal for many bacteria. The medium will determine which bacteria grow best. So if you don't see growth on one medium, but you see growth on another, it tells you that there is a difference in nutrients present in those media that is required for that bacteria. Look at your plates after 24 hr, then put them back in the incubator (keep them sterile) and look at them after 48 hrs--do you see the difference? any slow-growing bacteria visible or did the fast-growing take over the complete plate?
Sunspace basics
DOE Green Energy (OSTI)
Anyone who lives in a home with a sunspace will tell you that the sunspace is the most enjoyable room in the house. Many times the homeowner`s only regret is that the sunspace is not larger. Although aesthetics often drive the decision to add a sunspace or include one in a new home design, sunspaces can also provide supplemental space heating and a healthy environment for plants and people. In fact, a well-designed sunspace can provide up to 60% of a home`s winter heating requirements. This publication addresses basic elements of sunspace design; design considerations for supplemental space heating, growing plants, and use as a living space; design guidelines including siting, heat distribution, and glazing angles; and major sunspace components including glazing options, thermal mass, insulation, and climate controls. A list of sources for more information is also provided.

Physicists at Fermilab are searching for the smallest building blocks of Physicists at Fermilab are searching for the smallest building blocks of matter. Currently there are three kinds of building blocks: quarks, leptons and bosons. Read about Fermilab's search for the bottom and top quarks, the accelerator and detectors needed for their discovery, the spin-offs along the way, and the continuing efforts to reveal the basic particles and forces of nature. Searching for the Building Blocks of Matter was an exhibit for the public on the 15th floor of Wilson Hall at Fermi National Accelerator Laboratory. A committee of physicists and Fermilab employees developed the content for the exhibit. This web site includes the text and graphics from that exhibit. The entire text of the exhibit, not graphics, is available in PDF. Web Maintainer: email@example.com

Basic principle of superconductivity
The basic principle of superconductivity is suggested in this paper. There have been two vital wrong suggestions on the basic principle, one is the relation between superconductivity and the Bose-Einstein condensation (BEC), and another is the relation between superconductivity and pseudogap.

Search Combinators
The ability to model search in a constraint solver can be an essential asset for solving combinatorial problems. However, existing infrastructure for defining search heuristics is often inadequate. Either modeling capabilities are extremely limited or users are faced with a general-purpose programming language whose features are not tailored towards writing search heuristics. As a result, major improvements in performance may remain unexplored. This article introduces search combinators, a lightweight and solver-independent method that bridges the gap between a conceptually simple modeling language for search (high-level, functional and naturally compositional) and an efficient implementation (low-level, imperative and highly non-modular). By allowing the user to define application-tailored search strategies from a small set of primitives, search combinators effectively provide a rich domain-specific language (DSL) for modeling search to the user. Remarkably, this DSL comes at a low implementation cost to the...

Navigation computation in the smart cockpit
This thesis discusses the design and development of a hics. software module responsible for performing various navigation computations in the smart cockpit. The goals of decreased workload and increased situation awareness for the general aviation community are the motivating forces behind this software, the Navigation Module. The smart cockpit environment in which the Navigation Module operates is called the General Aviation Pilot Advisory and Training System (GAPATS) and was developed at Texas A&M University. The architecture of GAPATS is presented briefly followed by the functional requirements and operation of the Navigation Module. Next, an overview of the Navigation Module's software architecture is presented to describe how the object oriented methodology in C++ is used for the data abstraction in the Navigation Module. Other factors affecting the development of the Navigation Module are discussed such as the software development environment including useful tools available to the author. Next, results from pilot evaluations of GAPATS are given, noting where the data relate to the Navigation Module. These results show that the Navigation Module achieves its goal of a reduction in workload with an increase in situation awareness. Finally, recommendations are made that will improve future iterations of the Navigation Module, addressing its areas of weakness such as its database structure and flight planning abilities.

Biofuels Basics Biofuels Basics Content on this page requires a newer version of Adobe Flash Player. Get Adobe Flash player This video provides an overview of NREL research on converting biomass to liquid fuels. Text Version Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel. Ethanol is an alcohol, the same as in beer and wine (although ethanol used as a fuel is modified to make it undrinkable). It is most commonly made by fermenting any biomass high in carbohydrates through a process similar to beer brewing. Today, ethanol is made from starches and sugars, but NREL scientists are developing technology to allow it to be made from cellulose

Higgs Searches
We present the status and prospects of Higgs searches at the Tevatron and the LHC. Results from the Tevatron are using up to 5 fb{sup -} of data collected with the CDF and D0 detectors. The major contributing processes include associated production (WH {yields} l{nu}bb, ZH {yields} {nu}{nu}bb, ZH {yields} llbb) and gluon fusion (gg {yields} H {yields} WW{sup (*)}). Improvements across the full mass range resulting from the larger data sets, improved analyses techniques and increased signal acceptance are discussed. Recent results exclude the SM Higgs boson in a mass range of 160 < m{sub H} < 170 GeV. Searches for the neutral MSSM Higgs boson in the region 90 < m{sub A} < 200 GeV exclude tan {beta} values down to 30 for several benchmark scenarios.

Inertial navigation system for directional surveying
A Wellbore Inertial Navigation System (WINS) was developed and tested. Developed for directional surveying of geothermal, oil, and gas wells, the system uses gyros and accelerometers to obtain survey errors of less than 10 ft (approx. 3 m) in a 10,000-ft (approx. 300-m) well. The tool, which communicates with a computer at the surface, is 4 in. (approx. 10 cm) in diameter and 20 ft (approx. 6.1 m) long. The concept and hardware is based on a system developed by Sandia for flight vehicles.

Association search in semantic web: search + inference
Association search is to search for certain instances in semantic web and then make inferences from and about the instances we have found. In this paper, we propose the problem of association search and our preliminary solution for it using Bayesian network. We first minutely define the association search and its categorization. We then define tasks in association search. In terms of Bayesian network, we take ontology taxonomy as network structure in Bayesian network. We use the query log of instances to estimate the network parameters. After the Bayesian network is constructed, we give the solution for association search in the network.

Biodiesel station locator Biodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant greases. What is Biodiesel? Biodiesel is a liquid fuel made up of fatty acid alkyl esters, fatty acid methyl esters, or long-chain mono alkyl esters. It is produced from renewable sources such as new and used vegetable oils and animal fats and is a cleaner-burning replacement for petroleum-based diesel fuel. It is nontoxic and biodegradable. Like petroleum diesel, biodiesel is used to fuel compression-ignition (diesel) engines. B20, which is 20% biodiesel and 80% petroleum diesel, is
Biopower Basics | Department of Energy
Biopower Basics Biopower Basics Biopower Basics August 14, 2013 - 12:35pm Addthis Biopower is the production of electricity or heat from biomass resources. With 10 gigawatts of installed capacity, biopower technologies are proven options in the United States today. Biopower technologies include direct combustion, co-firing, and anaerobic digestion. Direct Combustion Most electricity generated from biomass is produced by direct combustion using conventional boilers. These boilers primarily burn waste wood products from the agriculture and wood-processing industries. When burned, the wood produces steam, which spins a turbine. The spinning turbine then activates a generator that produces electricity. Co-Firing Co-firing involves replacing a portion of the petroleum-based fuel in

Biofuel Basics Biofuel Basics Biofuel Basics July 30, 2013 - 11:38am Addthis Text Version Photo of a woman in goggles handling a machine filled with biofuels. Biofuels are liquid or gaseous fuels produced from biomass. Most biofuels are used for transportation, but some are used as fuels to produce electricity. The expanded use of biofuels offers an array of benefits for our energy security, economic growth, and environment. Current biofuels research focuses on new forms of biofuels such as ethanol and biodiesel, and on biofuels conversion processes. Ethanol Ethanol-an alcohol-is made primarily from the starch in corn grain. It is most commonly used as an additive to petroleum-based fuels to reduce toxic air emissions and increase octane. Today, roughly half of the gasoline sold in the United States includes 5%-10% ethanol.

Sure success partial search
Partial search has been proposed recently for finding the target block containing a target element with fewer queries than the full Grover search algorithm which can locate the target precisely. Since such partial searches will likely be used as subroutines for larger algorithms their success rate is important. We propose a partial search algorithm which achieves success with unit probability.

Quantum search with resonances
We present a continuous time quantum search algorithm analogous to Grover's. In particular, the optimal search time for this algorithm is proportional to $\\sqrt{N}$, where $N$ is the database size. This search algorithm can be implemented using any Hamiltonian with a discrete energy spectrum through excitation of resonances between an initial and the searched state. This algorithm is robust and, as in the case of Grover's, it allows for an error $O(1/\\sqrt{N})$ in the determination of the searched state. A discrete time version of this continuous time search algorithm is built, and the connection between the search algorithms with discrete and continuous times is established.

NREL: Learning - Energy Storage Basics
Energy Storage Basics Energy Storage Basics The demand for electricity is seldom constant over time. Excess generating capacity available during periods of low demand can be used to energize an energy storage device. The stored energy can then be used to provide electricity during periods of high demand, helping to reduce power system loads during these times. Energy storage can improve the efficiency and reliability of the electric utility system by reducing the requirements for spinning reserves to meet peak power demands, making better use of efficient baseload generation, and allowing greater use of renewable energy technologies. A "spinning reserve" is a generator that is spinning and synchronized with the grid, ready for immediate power generation - like a car engine running with the gearbox
NREL: Learning - Distributed Energy Basics
Distributed Energy Basics Distributed Energy Basics Photo of transmission towers and lines extending for miles towards a pink sunset in the distance. Distributed energy technologies can relieve transmission bottlenecks by reducing the amount of electricity that must be sent long distances down high-voltage power lines. Distributed energy refers to a variety of small, modular power-generating technologies that can be combined with load management and energy storage systems to improve the quality and/or reliability of the electricity supply. They are "distributed" because they are placed at or near the point of energy consumption, unlike traditional "centralized" systems, where electricity is generated at a remotely located, large-scale power plant and then transmitted down power lines to the consumer.
Microhydropower Basics | Department of Energy
Basics Basics Microhydropower Basics August 15, 2013 - 3:09pm Addthis Microhydropower systems are small hydroelectric power systems of less than 100 kilowatts (kW) used to produce mechanical energy or electricity for farms, ranches, homes, and villages. How a Microhydropower System Works All hydropower systems use the energy of flowing water to produce electricity or mechanical energy. Although there are several ways to harness moving water to produce energy, "run-of-the-river systems," which do not require large storage reservoirs, are most often used for microhydropower systems. Illustration of an example microhydropower system. A river flows down from some hills. The river first flows through an intake, which is indicated as two white walls on each side of the river. The intake diverts water to a canal. From the canal, the water travels to a forebay, which looks like a white, rectangular, aboveground pool. A pipeline, called a penstock, extends from the forebay to a building, called the powerhouse. You can see inside the powerhouse, which contains a turbine and other electric generation equipment. The water flows in and out of the powerhouse, returning to the river. Power lines also extend from the powerhouse, along and through two electrical towers, to a house that sits near the river's edge.

Anytime Heuristic Search
We describe how to convert the heuristic search algorithm A* into an anytime algorithm that finds a sequence of improved solutions and eventually converges to an optimal solution. The approach we adopt uses weighted heuristic search to find an approximate solution quickly, and then continues the weighted search to find improved solutions as well as to improve a bound on the suboptimality of the current solution. When the time available to solve a search problem is limited or uncertain, this creates an anytime heuristic search algorithm that allows a flexible tradeoff between search time and solution quality. We analyze the properties of the resulting Anytime A* algorithm, and consider its performance in three domains; sliding-tile puzzles, STRIPS planning, and multiple sequence alignment. To illustrate the generality of this approach, we also describe how to transform the memory-efficient search algorithm Recursive Best-First Search (RBFS) into an anytime algorithm.

Faceted Semantic Search for Personalized Social Search
Actual social networks (like Facebook, Twitter, Linkedin, ...) need to deal with vagueness on ontological indeterminacy. In this paper is analyzed the prototyping of a faceted semantic search for personalized social search using the "joint meaning" in a community environment. User researches in a "collaborative" environment defined by folksonomies can be supported by the most common features on the faceted semantic search. A solution for the context-aware personalized search is based on "joint meaning" understood as a joint construal of the creators of the contents and the user of the contents using the faced taxonomy with the Semantic Web. A proof-of concept prototype shows how the proposed methodological approach can also be applied to existing presentation components, built with different languages and/or component technologies.

The Language of Search
This paper is concerned with a class of algorithms that perform exhaustive search on propositional knowledge bases. We show that each of these algorithms defines and generates a propositional language. Specifically, we show that the trace of a search can be interpreted as a combinational circuit, and a search algorithm then defines a propositional language consisting of circuits that are generated across all possible executions of the algorithm. In particular, we show that several versions of exhaustive DPLL search correspond to such well-known languages as FBDD, OBDD, and a precisely-defined subset of d-DNNF. By thus mapping search algorithms to propositional languages, we provide a uniform and practical framework in which successful search techniques can be harnessed for compilation of knowledge into various languages of interest, and a new methodology whereby the power and limitations of search algorithms can be understood by looking up the tractability and succinctness of the corresponding propositional l...

Underwater acoustic navigation with the WHOI micro-modem
Abstract � The WHOI Micro-Modem is a compact, low-power acoustic transceiver that can provide both acoustic telemetry and navigation. Its size and versatility make it ideal for integration in autonomous underwater vehicles (AUVs). The modem supports the use of both broadband and narrowband transponders for long baseline navigation systems, has a modem-to-modem ranging capability, and can be configured to provide synchronous oneway ranging, when integrated with a precision clock. This paper gives an overview of the different navigation systems supported by the Micromodem and presents the results from field tests conducted on the SeaBED AUV in deployments in Greece, the Bluefin AUV, and whale localizations in the Stellwagen Bank Marine Sanctuary.

Frequency Regulation Basics and Trends
The electric power system must address two unique requirements: the need to maintain a near real-time balance between generation and load, and the need to adjust generation (or load) to manage power flows through individual transmission facilities. These requirements are not new: vertically integrated utilities have been meeting them for a century as a normal part of conducting business. With restructuring, however, the services needed to meet these requirements, now called ''ancillary services'', are being more clearly defined. Ancillary services are those functions performed by the equipment and people that generate, control, and transmit electricity in support of the basic services of generating capacity, energy supply, and power delivery. The Federal Energy Regulatory Commission (FERC) has defined such services as those ''necessary to support the transmission of electric power from seller to purchaser given the obligations of control areas and transmitting utilities within those control areas to maintain reliable operations of the interconnected transmission system''. This statement recognizes the importance of ancillary services for both bulk-power reliability and support of commercial transactions. Balancing generation and load instantaneously and continuously is difficult because loads and generators are constantly fluctuating. Minute-to-minute load variability results from the random turning on and off of millions of individual loads. Longer-term variability results from predictable factors such as the daily and seasonal load patterns as well as more random events like shifting weather patterns. Generators also introduce unexpected fluctuations because they do not follow their generation schedules exactly and they trip unexpectedly due to a range of equipment failures. The output from wind generators varies with the wind. Storage technologies should be ideal suppliers of several ancillary services, including regulation, contingency reserves (spinning reserve, supplemental reserve, replacement reserve), and voltage support. These services are not free; in regions with energy markets, generators are paid to supply these services. In vertically integrated utilities (without energy markets) the utility incurs significant costs to supply these services. Supplying these services may be a significant business opportunity for emerging storage technologies. This report briefly explores the various ancillary services that may be of interest to storage. It then focuses on regulation, the most expensive ancillary service. It also examines the impact that increasing amounts of wind generation may have on regulation requirements, decreasing conventional regulation supplies, and the implications for energy storage.

Intermittent search strategies
This review examines intermittent target search strategies, which combine phases of slow motion, allowing the searcher to detect the target, and phases of fast motion during which targets cannot be detected. We first show that intermittent search strategies are actually widely observed at various scales. At the macroscopic scale, this is for example the case of animals looking for food ; at the microscopic scale, intermittent transport patterns are involved in reaction pathway of DNA binding proteins as well as in intracellular transport. Second, we introduce generic stochastic models, which show that intermittent strategies are efficient strategies, which enable to minimize the search time. This suggests that the intrinsic efficiency of intermittent search strategies could justify their frequent observation in nature. Last, beyond these modeling aspects, we propose that intermittent strategies could be used also in a broader context to design and accelerate search processes.

Correlations in Grover search
Grover search is a well-known quantum algorithm that outperforms any classical search algorithm. It is known that quantum correlations such as entanglement are necessary for the power of quantum computation. But entanglement is not the only kind of quantum correlations. Other quantum correlations such as quantum discord are also useful to capture some aspects of the nonclassical correlation. We investigate several kinds of correlations including both quantum and classical in the whole process of Grover search algorithm. These correlations are the concurrence, entanglement of formation, quantum discord, classical correlation and mutual information. The behaviors of quantum discord, classical correlation and mutual information are almost the same while the concurrence is different. When the search is over, all kinds of correlations are zero, we argue that this is necessary for the final step in the search.

Binary Quantum Search
Database search has wide applications and is used as a subroutine in many important algorithms. We shall consider a database with one target item. Quantum algorithm finds the target item in a database faster than any classical algorithm. It frequently occurs in practice that only a portion of information about the target item is interesting, or we need to find a group of items sharing some common feature as the target item. This problem is in general formulated as search for a part of the database [a block] containing the target item, instead of the item itself. This is partial search. Partial search trades accuracy for speed, i.e. it works faster than a full search. Partial search algorithm was discovered by Grover and Radhakrishnan. We shall consider optimized version of the algorithm and call it GRK. It can be applied successively [in a sequence]. First the database is partitioned into blocks and we use GRK to find the target block. Then this target block is partitioned into sub-blocks and we use GRK again to find the target sub-block. [We can call it binary quantum search.] Another possibility is to partition the database into sub-blocks directly and use GRK to find the target sub-block in one time. In this paper we prove that the latter is faster [makes less queries to the oracle].

Automated search for supernovae
This thesis describes the design, development, and testing of a search system for supernovae, based on the use of current computer and detector technology. This search uses a computer-controlled telescope and charge coupled device (CCD) detector to collect images of hundreds of galaxies per night of observation, and a dedicated minicomputer to process these images in real time. The system is now collecting test images of up to several hundred fields per night, with a sensitivity corresponding to a limiting magnitude (visual) of 17. At full speed and sensitivity, the search will examine some 6000 galaxies every three nights, with a limiting magnitude of 18 or fainter, yielding roughly two supernovae per week (assuming one supernova per galaxy per 50 years) at 5 to 50 percent of maximum light. An additional 500 nearby galaxies will be searched every night, to locate about 10 supernovae per year at one or two percent of maximum light, within hours of the initial explosion.

Photovoltaic Cell Structure Basics | Department of Energy
Structure Basics Structure Basics Photovoltaic Cell Structure Basics August 19, 2013 - 4:50pm Addthis The actual structural design of a photovoltaic (PV), or solar cell, depends on the limitations of the material used in the PV cell. The four basic device designs are: Homojunction Devices Crystalline silicon is the primary example of this kind of cell. A single material-crystalline silicon-is altered so that one side is p-type, dominated by positive holes, and the other side is n-type, dominated by negative electrons. The p/n junction is located so that the maximum light is absorbed near it. The free electrons and holes generated by light deep in the silicon diffuse to the p/n junction and then separate to produce a current if the silicon is of sufficiently high quality. In this homojunction design, these aspects of the cell may be varied to
Air-Conditioning Basics | Department of Energy
Air-Conditioning Basics Air-Conditioning Basics Air-Conditioning Basics August 16, 2013 - 1:59pm Addthis Air conditioning is one of the most common ways to cool homes and buildings. How Air Conditioners Work Air conditioners employ the same operating principles and basic components as refrigerators. Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings; likewise, an air conditioner uses energy to transfer heat from the interior space to the relatively warm outside environment. An air conditioner uses a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.

Cooling System Basics Cooling System Basics Cooling System Basics August 16, 2013 - 1:08pm Addthis Cooling technologies used in homes and buildings include ventilation, evaporative cooling, air conditioning, absorption cooling, and radiant cooling. Learn more about how these technologies work. Ventilation Ventilation allows air to move into and out of homes and buildings either by natural or mechanical means. Evaporative Cooling In dry climates, evaporative cooling or "swamp cooling" provides an experience like air conditioning, but with much lower energy use. An evaporative cooler uses the outside air's heat to evaporate water inside the cooler. The heat is drawn out of the air and the cooled air is blown into the space by the cooler's fan. Air Conditioning Air conditioners, which employ the same operating principles and basic

Solar Energy Resource Basics Solar Energy Resource Basics Solar Energy Resource Basics August 21, 2013 - 11:40am Addthis Solar radiation, often called the solar resource, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies. However, the technical feasibility and economical operation of these technologies at a specific location depends on the available solar resource. Basic Principles Every location on Earth receives sunlight at least part of the year. The amount of solar radiation that reaches any one spot on the Earth's surface varies according to: Geographic location Time of day Season Local landscape Local weather. Because the Earth is round, the sun strikes the surface at different
Photovoltaic System Basics | Department of Energy
System Basics System Basics Photovoltaic System Basics August 20, 2013 - 4:00pm Addthis A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules. Modules, in turn, can be connected to form even larger units called arrays, which can be interconnected to produce more power, and so on. In this way, PV systems can be built to meet almost any electric power need, small or large. Illustration of solar cells combined to make a module and modules combined to make an array.

Absorption Cooling Basics | Department of Energy
Cooling Basics Cooling Basics Absorption Cooling Basics August 16, 2013 - 2:26pm Addthis Absorption coolers use heat rather than electricity as their energy source. Because natural gas is the most common heat source for absorption cooling, it is also referred to as gas-fired cooling. Other potential heat sources include propane, solar-heated water, or geothermal-heated water. Although mainly used in industrial or commercial settings, absorption coolers are commercially available for large residential homes. How Absorption Cooling Works An absorption cooling cycle relies on three basic principles: When a liquid is heated it boils (vaporizes) and when a gas is cooled it condenses Lowering the pressure above a liquid reduces its boiling point Heat flows from warmer to cooler surfaces.
Active Solar Heating Basics Active Solar Heating Basics Active Solar Heating Basics August 16, 2013 - 3:23pm Addthis There are two basic types of active solar heating systems based on the type of fluid-either liquid or air-that is heated in the solar energy collectors. The collector is the device in which a fluid is heated by the sun. Liquid-based systems heat water or an antifreeze solution in a "hydronic" collector, whereas air-based systems heat air in an "air collector." Both of these systems collect and absorb solar radiation, then transfer the solar heat directly to the interior space or to a storage system, from which the heat is distributed. If the system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat. Liquid systems are more often used when storage is included, and are well

Using doppler radar images to estimate aircraft navigational heading error
A yaw angle error of a motion measurement system carried on an aircraft for navigation is estimated from Doppler radar images captured using the aircraft. At least two radar pulses aimed at respectively different physical locations in a targeted area are transmitted from a radar antenna carried on the aircraft. At least two Doppler radar images that respectively correspond to the at least two transmitted radar pulses are produced. These images are used to produce an estimate of the yaw angle error.

Leptoquark searches in TESLA
Leptoquark searches are considered for possible future e + e and e experiments at TESLA. Expected exclusion limits from direct leptoquark searches are compared with indirect limits expected from the contact interaction analysis. If the leptoquark signal suggested by the existing data is detected at LHC, with mass below 1 TeV, TESLA will be an ideal place to study its properties, provided that the leptoquark Yukawa coupling is not too small. Key words: Leptoquarks, Future colliders, Searches PACS: 12.60.i, 14.80.j 1 Introduction New result on atomic parity violation (APV) in Cesium and unitarity of the CKM matrix, as well as recent LEP2 hadronic cross-section measurements indicate possible deviations from the Standard Model predictions. Exchange of leptoquark type objects has been proposed as a possible explanation for these eects (1). If the observed signal is real it should become clearly visible in future colliders.

The basis for much of the theory of particle scattering and hadron spectroscopy is the construction of the hadrons from a set of fractionally charged constituents (quarks). A central but unproven hypothesis of this theory, Quantum Chromodynamics, is that quarks cannot be observed as free particles but are confined to mesons and baryons. Experiments show that it is at best difficult to �unglue� quarks. Accelerator searches at increasing energies have produced no evidence for free quarks, while only a few cosmic-ray and matter searches have produced uncorroborated events. This compilation is only a guide to the literature, since the quoted experimental limits are often only indicative. Reviews

Search for Gluonic Excitations
Studies of meson spectra via strong decays provide insight regarding QCD at the confinement scale. These studies have led to phenomenological models for QCD such as the constituent quark model. However, QCD allows for a much richer spectrum of meson states which include extra states such as exotics, hybrids, multi-quarks, and glueballs. First discussion of the status of exotic meson searches is given followed by a discussion of plans at Jefferson Lab to double the energy of the machine to 12 GeV, which will allow us to access photoproduction of mesons in search for gluonic excited states.

Absorption Heat Pump Basics | Department of Energy
Absorption Heat Pump Basics Absorption Heat Pump Basics Absorption Heat Pump Basics August 19, 2013 - 11:11am Addthis Absorption heat pumps are essentially air-source heat pumps driven not by electricity, but by a heat source such as natural gas, propane, solar-heated water, or geothermal-heated water. Because natural gas is the most common heat source for absorption heat pumps, they are also referred to as gas-fired heat pumps. There are also absorption coolers available that work on the same principal, but are not reversible and cannot serve as a heat source. These are also called gas-fired coolers. How Absorption Heat Pumps Work Residential absorption heat pumps use an ammonia-water absorption cycle to provide heating and cooling. As in a standard heat pump, the refrigerant (in this case, ammonia) is condensed in one coil to release its heat; its
LED Lighting Basics | Department of Energy
LED Lighting Basics LED Lighting Basics LED Lighting Basics August 16, 2013 - 10:07am Addthis Light-emitting diodes (LEDs) are light sources that differ from more traditional sources of light in that they are semiconductor devices that produce light when an electrical current is applied. Applying electrical current causes electrons to flow from the positive side of a diode to the negative side. Then, at the positive/negative junction of the diode, the electrons slow down to orbit at a lower energy level. The electrons emit the excess energy as photons of light. LEDs are often used as small indicator lights on various electronic devices. Because of their long life, durability, and efficiency, LEDs are becoming more common in residential, commercial, and outdoor area lighting
Concentrator Photovoltaic System Basics | Department of Energy
Concentrator Photovoltaic System Basics Concentrator Photovoltaic System Basics Concentrator Photovoltaic System Basics August 20, 2013 - 4:12pm Addthis Concentrator photovoltaic (PV) systems use less solar cell material than other PV systems. PV cells are the most expensive components of a PV system, on a per-area basis. A concentrator makes use of relatively inexpensive materials such as plastic lenses and metal housings to capture the solar energy shining on a fairly large area and focus that energy onto a smaller area-the solar cell. One measure of the effectiveness of this approach is the concentration ratio-in other words, how much concentration the cell is receiving.
