This paper deals with the problem of the optimal location of warehouses in the two stage distribution system, i.e., the distribution system where the product is transported from plants to customer areas via warehouses. The Problem is formulated with a zero-one mixed integer programming and an efficient branch and bound algorithm is then used to solve the problem. In order to obtain the solution of this problem, this paper shows the procedure of conversion of two stage distribution system into one stage distribution system. An improved method of solving the linear programming at the nodes and branching decision rule is also showed by this study.


This study is done to identify significantly expressed genes of influenza A virus infection in human, facilitated by the idea of checking for the presence of immune related genes in these significantly expressed genes, followed by the analysis of their potential mechanism and pathway. Considering the usage of microarray dataset, the gene expression profile GSE66597 was downloaded from the gene expression omnibus(GEO) database, and then a subsequent generation of differentially expressed genes(DEGs) using the GEO2R tool. A total of 1107 genes was generated with 703 upregulated and 404 downregulated genes. The protein-protein interaction (PPI) network was constructed using string and Cytoscape software which resulted in generating the core genes, hub genes, and bottleneck genes. Subsequent Venn diagram analysis finally gave the six candidate genes CRP, CCL5, IL17A, STAT1, CD34, SPI1, subjected to gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) for enrichment and pathway analysis respectively. Out of the initial six candidate genes, four of these genes CRP, CCL5, IL17A, are immune related, and initiated particularly by the presence of influenza A virus.


Considering the outdoor environment at the initial stage of design process plays a significant role on future building performance. Augmented Reality (AR) technology applied in this research can integrate real world building morphology information and virtual world ventilation information seamlessly that rapidly and directly provides designers information for observation and evaluation. During the case study of "2017 Shanghai DigitalFUTURE" summer workshop, a research on augmented reality technology based wind environment visualization was carried on. The achievement with an application software not only showed the geometric information of the real world objects (such as buildings), but also the virtual wind environment has displayed. Thus, these two kinds of information can complement and superimpose each other. This AR technology based software brings multiple synthetic together, which can (1) visualize the air flow around buildings that provides designers rapid and direct information for evaluation; (2) deal with wind-environment-related data quantitatively and present in an intuitive, easy-to-interpret graphical way; and (3) be further developed as a visualization system based on built-in environments in the future, which contributes to rapid evaluation of a series of programs at the beginning of the building design.


It is well-known that for any commutative unitary ring R , the Serre conjecture ring R h X i , i.e., the localization of the univariate polynomial ring R [ X ] at monic polynomials, is a B´ezout domain of Krull dimension ≤ 1 if so is R . Consequently, defining by induction R h X 1 , . . . , X n i := ( R h X 1 , . . . , X n − 1 i ) h X n i , the ring R h X 1 , . . . , X n i is a B´ezout domain of Krull dimension ≤ 1 if so is R . The fact that R h X 1 , . . . , X n i is a B´ezout domain when R is a valuation domain of Krull dimension ≤ 1 was the cornerstone of Brewer and Costa's theorem stating that if R is a one-dimensional arithmetical ring then finitely generated projective R [ X 1 , . . . , X n ]-modules are extended. It is also the key of the proof of the Gr¨obner Ring Conjecture in the lexicographic order case, namely the fact that for any valuation domain R of Krull dimension ≤ 1, any n ∈ N > 0 , and any finitely generated ideal I of R [ X 1 , . . . , X n ], the ideal LT( I ) generated by the leading terms of the elements of I with respect to the lexicographic monomial order is finitely generated. Since the ring R h X 1 , . . . , X n i can also be defined directly as the localization of the multivariate polynomial ring R [ X 1 , . . . , X n ] at polynomials whose leading coefficients according to the lexicographic monomial order with X 1 < X 2 < · · · < X n is 1, we propose to generalize the fact that R h X 1 , . . . , X n i is a B´ezout domain of Krull dimension ≤ 1 if so is R to any rational monomial order, bolstering the evidence for the Gr¨obner Ring Conjecture in the rational case. We give an example showing that this result is no more true in the irrational case.


In a survey at the University of Regina, undergraduate students were asked to state their views about goals, aims, and problems associated with multiculturalism and immigration. These views and their connections with attitudes on other political and social issues are analyzed in this paper. A multiple regression model is used to demonstrate a strong connection between support for immigration and views on social values, jobs, immigrant integration, and multicultural principles. Little connection was found between political orientation and support for immigration. Policy implications include expanding support for programs dealing with diversity and other multicultural principles as well as developing labour market policies to assure jobs and adequate training for new labour force entrants.


Since the pioneering attempts by Scholander et al. (1961), the observation that the porous spaces in natural ice contain samples of ancient air, the study of ice cores for potential insights into the history of the atmospheric CO2 concentration has received great attention from scientists interested in the reconstruction of environmental parameters. Progress, however, was made possible only because deep ice cores from Greenland and Ant arctica, which are continuous sequences of generally high-quality samples formed during the last 100,000 and 50,000 years, respectively, were avail able for study. Research has led to new techniques for extracting gases from ice and to recent developments of sensitive and accurate techniques for the analysis of gas. Today, analysis of gas concentrations in air en trapped in natural ice is considered to be the most promising method for reconstructing the history of the atmospheric CO2 concentration (WMO 1983). In this chapter, we describe the state of the art of this research. A crucial question relates to the occlusion of air in ice and to possible mechanisms leading to deviations of the gas composition of the trapped air from that of the atmosphere at the time of ice formation and during the long storage time of the air bubbles in the surrounding ice matrix. For ice formed in very cold regions, it can be expected that the CO2 content ofthe occluded air indeed closely reflects that of the ancient atmosphere. Therefore, we give an overview of data that we consider to be representative of the atmospheric CO2 concentration and its variation during the recent prein dustrial period, and also during the last glaciation (the Wisconsin) with its termination. The Wisconsin glacial stage was a period with environ mental conditions drastically different from those of today and with events of rapid climatic change. The CO2 concentration during the recent prein dustrial period is closely related to questions in carbon-cycle modeling regarding natural and anthropogenic sources and sinks; it is also closely related to the detection of CO2-induced warming and the sensitivity of climate to rising CO2 • The CO 2 changes observed during periods of rapid


The development of natural fiber reinforced composite material is increasing at very fast rate due to their eco-friendly and biodegradable nature. NFCs natural fiber reinforced composites have various properties such as low cost, low density, recyclability, renewability and good physical and mechanical strength. NFCs have wide range of applications such as in automobile, sports, aerospace, marine, home appliances and in building construction. In this paper we used prosopis juliflora desert plant fibers as a filler to make biodegradable composites and alkali treatment was done to modification of fiber in order to make high strength composites materials. By using scanning electron microscopy (SEM), water absorption tests, and Fourier transform infrared spectroscopy (FTIR), this paper examines the effects of surface modification on the fibers. By conducting SEM analysis it has been observed that the chemical treatment of fibers can improve adhesion of the composites. Water absorption test concluded that due to the higher porosity and better surface energy of the treated fiber it had a higher rate of water absorption than the untreated fibers. FTIR results concluded that due to more crystalline structure and more ordered structure crystallinity index of the treated fibers increases compared to untreated fibers. FTIR results proves that TCI total crystallinity index and the LOI lateral order index is high for PJ treated fibers as compared to untreated PJ fibers.


Dr Jeffrey R. Botkin, 1 in his article "Informed Consent for Lumbar Puncture," which appears in this issue of AJDC , provides physicians with an adequate legal definition of the concept of "informed consent." While I might, on technical grounds, have some objections to the way he describes the exceptions to the requirement for informed consent (see below), I think his articulation of the general principles is useful. Unfortunately, informed consent is not a concept with unvarying meaning. It is used in many See also p 899. different contexts and has many different meanings, depending on the court or commentator who is attempting to use the phrase. The two words, however, have generally accepted contextual meaning. Thus, "informed" means knowing, understanding, or aware. It does not mean the mere telling of fact, particularly when that information is not understood by the recipient. Thus, if I give the information in a language


Structural equation modeling is a multivariate data analysis technique that allows researchers to concurrently analyze multiple relationships among manifest and latent variables. Two main approaches to SEM exist: covariance-based and variance-based. Variance-based SEM has been gaining attention in the past few years due to its flexibility. Among other features, it performs well under deviations of multivariate normality, and generally requires smaller sample sizes than covariance-based SEM. This tutorial will discuss variance-based SEM in the context of a behavioral study of communication in virtual teams. The software used in the tutorial will be WarpPLS 1.0, developed by the presenter and available at warppls.com. WarpPLS 1.0 is an easy-to-use variance-based SEM software that allows for the modeling of direct, mediating, and moderating effects among latent variables.


Abstract A simple, two-constant, constitutive relation, applicable over the entire range of strains, is proposed for rubber networks. Behavior in simple extension is derived as an example.


This article assesses Zimbabwean health services, using a social workers' social development paradigm to analyze the dynamics of Zimbabwe's Social Security program, focusing on universal health access for older persons, orphans, and vulnerable children. This article identifies the key factors that have done the most to shape health policy administration in the broader context of social policies and social security in Zimbabwe. The discussion is framed around the need for pro-poor social policies, social inclusivity, and the efforts to ensure universal health access. Despite numerous reports, newspaper op-eds and consultancy documents offering opinions on the state of social service delivery in the country, most critics lack empirical data and end up being very anecdotal as they critique the present system. The socioeconomic context of Zimbabwe is therefore analyzed here, with the best available statistical evidence provided, followed by assessment of social policy interventions. Current challenges to access health services are evaluated using a human rights-based social policy approach. The recent Zimbabwe Ministry of Finance-led consultative process crafted a 2016 document, the Poverty Reduction Strategies Papers (PRSPs), as an overall strategy for transforming the Zimbabwean health sector. The article concludes by recommending community-based health insurance approach as most appropriate intervention for ensuring health inclusivity and enhancing health for all in Zimbabwe.


The research showed that the pre-sowing oat's seed processing with growth regulators and bacterial specimens improves the productivity of the crop and the quality of the final product. The positive changes have been noticed not only in technological characteristics of grain ( the increase of grain nature, the decrease of hoodness) but also in the whole content of vitamins and protein, which helps to increase the biological value of the product.


Colorectal cancer (CRC) is the third most frequent cancer worldwide and the fourth leading cause of death due to cancer. The development of this disease usually occurs due to the progression of precursor lesions in the normal intestinal mucosa to tumor. Environment, age, lifestyle, and genetic background are considered risk factors for the development and progression of CRC. The molecular abnormalities involved in the progression of CRC have been well characterized, including mutations, microsatellite instability, and epigenetic changes. Although the molecular profile of colorectal cancer is well known in developed countries, in the Brazilian population information is still very limited. Therefore, in the present study we intended to characterize the mutation profile of a Brazilian population and associate this with their clinicopathologic features. A total of 61 colorectal cancer cases of different stages were included. DNA was extracted from frozen fresh tumors and sequenced using a panel of 298 genes by next-generation sequencing (NGS). The mean age of patients was 63 years old; 57.4% were male. Three patients had CRC in stage 0, 16 in stage I, 29 in stage II, 10 in stage III, and three in stage IV. Considering only nonsynonymous alterations, we found on average 7.24 mutations per patient. The majority were missense (61.8%), followed by nonsense (15.2%) and frameshift mutations (10.9%). The genes most frequently mutated were APC (78.7%), TP53 (72.1%), KRAS (60.7%), PIK3CA (14.8%), and FBXW7 (14.8%). Alterations in tumor suppressor genes such as APC and TP53 were found throughout the entire gene. On the other hand, oncogenes such as KRAS had alterations in hotspots of the gene. In conclusion, the frequency of alterations in genes sequenced in our population was similar to that found in the international literature for other populations.

Food supply chains generate a significant portion of CO2 emissions, because of the large volume of food transportation and the large number and frequency of trips made to deliver food products to the retailing stores, making it available to the customers. Collaboration of partners in food supply chains will lead to reducing CO2 emissions. Such collaboration could be in form of sharing trucks by retailers, in order to increase fill rate of the vehicles and to reduce their empty running. This paper presents a formulation for a green collaborative transport planning model with time windows. A case study is carried out in order to measure the reduced travelled distance for delivery of products and the reduced amount of CO2 emissions, as a result of implementing collaborative distribution. The numericalcontribution of the paper is important for showing the role of collaborative distribution for developing green supply chain management and illustratedby anapplication to a real case of logistics and product delivery.


IN 1969, Minniiesota became one of the twenty-two states which have to date amended or revised their dental practice acts to allow for expanded functions of dental hygienists and/or dental assistants.1 It is also one of eight states which have allowed for expanded functions for both of these auxiliaries. The Minnesota Board of Dentistry has reviewed preliminary recommendations and is currently finalizing them with respect to specific duties which may be delegated to licensed and unlicensed auxiliaries. With the enactment of the new law, Minnesota also became the first state to require mandatory continuing education for dentists and hygienists in order to maintain licensure. This legislation may produce fundamental changes in the way that dental services are rendered in Minnesota, and may provide a mechanism to meet an increase in demand for dental services. The changes in state dental practice acts, in combination with consumer pressures for change in the health care delivery system, place new demands on the dental practitioner and bring to the surface new issues which he now faces. If changes in these practice acts are to make a significant impact on the health care delivery system, they must have the active support of those engaged in delivering the service. It has been generally acknowledged by dental leaders that some change in the system may be necessary; however, there is little information which indicates that the practicing dentist concurs in this view. Therefore, the present and future deliverers of dental care were surveyed to see how they perceived some of the problems facing the profession today which are related to recent and proposed changes.


This paper deals with the development of an interactive and user friendly environment for the simulation of flexible manipulator system. A constrained planer single-link flexible manipulator is considered for this environment. Simulation algorithm is based on finite difference method where the systems governing dynamic equation is discretized and implemented within simulink environment. This environment has proven to be a valuable educational tool for understanding the behaviour of flexible manipulator system and development of various controller designs. The environment can be used as a computer aided teaching facility and also a test-bed for newly designed controllers for flexible manipulator systems. Both open-loop and closed-loop control strategies were also incorporated within the environment.

Migration of Np through the subsurface is expected to be primarily controlled by sorption to sediments. Therefore, understanding and quantifying Np sorption to sediments and sediments from the Savannah River Site (SRS) is vital to ensure safe disposal of Np bearing wastes. In this work, Np sorption to two sediments representing the geological extremes with respect to sorption properties expected in the SRS subsurface environment (named 'subsurface sandy sediment' and 'subsurface clayey sediment') was examined under a variety of conditions. First a series of baseline sorption tests at pH 5.5 under an oxic atmosphere was performed to understand Np sorption under typical subsurface conditions. These experiments indicated that the baseline K{sub d} values for the subsurface sandy and subsurface clayey sediments are 4.26 {+-} 0.24 L kg{sup -1} and 9.05 {+-} 0.61 L kg{sup -1}, respectively. These Np K{sub d} values of SRS sediments are the first to be reported since Sheppard et al. (1979). The previous values were 0.25 and 0.16 L kg{sup -1} for a low pH sandy sediment. To examine a possible range of K{sub d} values under various environmental scenarios, the effects of natural organic matter (NOM, also a surrogate for cellulose degradation products), the presencemore » of various chemical reductants, and an anaerobic atmosphere on Np sorption were examined. The presence of NOM resulted in an increase in the Np K{sub d} values for both sediments. This behavior is hypothesized to be the result of formation of a ternary Np-NOM-sediment complex. Slight increases in the Np sorption (K{sub d} 13-24 L kg{sup -1}) were observed when performing experiments in the presence of chemical reductants (dithionite, ascorbic acid, zero-valent iron) or under anaerobic conditions. Presumably, the increased sorption can be attributed to a slight reduction of Np(V) to Np(IV), the stronger sorbing form of Np. The most significant result of this study is the finding that Np weakly sorbs to both end member sediments and that Np only has a slight tendency to reduce to its stronger sorbing form, even under the most strongly reducing conditions expected under natural SRS conditions. Also, it appears that pH has a profound effect on Np sorption. Based on the these new measurements and the revelations about Np redox chemistry, the following changes to 'Best K{sub d}' values, as defined in Kaplan (2006), for SRS performance assessment calculations are recommended.« less

A new approach to modelling distributed systems is presented. It uses sequential processes and event synchronization as building blocks to construct a cohesive picture of the interdependent requirements for the functionality, architecture, scheduling policies, and performance attributes of a distributed system. A language called CSPS (an extension of Hoare's CSP) is used in the illustration of the approach. Employing CSP as a base allows modelled systems to be verified using techniques already developed for verifying CSP programs and leads to the emergence of a uniform incremental strategy for verifying both logical and performance properties of distributed systems.

This study was instigated in view of the recent commercial exploitation of the Doba oil field in landlocked Chad, which is a region from which crude oil is extracted and expected to be routed to the Atlantic shore through pipeline transportation. Thus, nonisothermal kinetic hydrovisbreaking tests of Doba crude oil were conducted in a mechanically stirred baffled autoclave reactor under various conditions to alter the rheological properties of the treated crude. The crude hydrovisbreaking kinetics was modeled based on the four-parameter reaction severity concept (ω, γ, E, βo), as a function of the conversion in polyaromatics and polar maltenic subfractions. The hydrovisbreaking of Doba crude was observed to be a pseudo-first-order reaction (i.e., in excess of H2), with respect to the polyaromatics and polar maltenic conversion. The following assortment of kinetic parameters was identified under noncatalytic hydrovisbreaking conditions:  heterogeneity coefficient, γ = 1; characteristic temperature, ω = 29.9...


Understanding the exact details of deviation zone related to a manufactured surface needs measurement of infinite number of points. Coordinate metrology provides deviation of the limited number of discrete points on a measured surface, but typically it is not capable to explore any information of the surface regions between these measured points. An approach to estimate the Distribution of Geometric Deviations (DGD) on the entire inspected surface is presented in this paper. The methodology is developed based on estimation of mean value property of the harmonic functions and Laplace equation. The resulting DGD model can be employed to estimate the deviation values at any unmeasured point of the inspected surface when a detailed understanding of the surface geometric deviations is required. Implementation of the developed methodology is described and case studies for typical industrial parts are presented. This methodology can be used for closed-loop of inspection and manufacturing processes when a compensation scheme is available to compensate the manufacturing errors based on the DGD model.Copyright © 2014 by ASME


An interim report is presented illustrating differences in physiological response to atropine among mental defectives of low and high-grade intelligence. Epileptics, and patients with evidence of organic brain lesions, were excluded from the series. Certain types of response common in schizophrenics occur more frequently among the low-grade defectives, and show increasing intensity over the period of adolescence, while the converse is true of high-grade groups. A concept of 'inadequate improvement on pre-existing schizophrenic tendencies' is postulated as a factor in determining the degree of intellectual deficiency in mental defectives of this series. A speculative attempt is made to reconcile this finding with our current knowledge of mental growth in childhood, and is advanced as a possible line of thought for further research.

The Korea Microlensing Telescope Network (KMTNet) is a wide-field photometric system installed by the Korea Astronomy and Space Science Institute (KASI). Here, we present the overall technical specifications of the KMTNet observation system, test observation results, data transfer and image processing procedure, and finally, the KMTNet science programs. The system consists of three 1.6 m wide-field optical telescopes equipped with mosaic CCD cameras of 18k by 18k pixels. Each telescope provides a 2.0 by 2.0 square degree field of view. We have finished installing all three telescopes and cameras sequentially at the Cerro-Tololo Inter-American Observatory (CTIO) in Chile, the South African Astronomical Observatory (SAAO) in South Africa, and the Siding Spring Observatory (SSO) in Australia. This network of telescopes, which is spread over three different continents at a similar latitude of about -30 degrees, enables 24-hour continuous monitoring of targets observable in the Southern Hemisphere. The test observations showed good image quality that meets the seeing requirement of less than 1.0 arcsec in I-band. All of the observation data are transferred to the KMTNet data center at KASI via the international network communication and are processed with the KMTNet data pipeline. The primary scientific goal of the KMTNet is to discover numerous extrasolar planets toward the Galactic bulge by using the gravitational microlensing technique, especially earth-mass planets in the habitable zone. During the non-bulge season, the system is used for wide-field photometric survey science on supernovae, asteroids, and external galaxies.

The general analytical solution of a collisional‐radiative model, including atom–atom inelastic collisions, for nonequilibrium, partially ionized, steady‐state plasmas is presented. This is applied to argon plasmas and the results are compared with previous numerical calculations. The model includes three atomic energy levels; the ground level, one excited level, and continuum, and assumes a Maxwellian electron and atom distribution functions. All rates for collisional and radiative processes are expressed as analytical functions. The model is solved algebraically to obtain analytical expressions for the electron and excited atom densities as a function of the plasma parameters. In the limit of an optically thick plasma the solution agrees with results for complete thermodynamic equilibrium. Solutions are presented for a wide range of conditions (3000≤Te≤24 000 K, 105≤Ne≤NA cm−3, 1014≤NA≤1018 cm−3).


The Information Literacy agenda of academic libraries has recently been critically examined to uncover some of its inherent problems. This paper frames these discussions in the critical theoretical perspective present in educational research, suggesting that the emergence of critical information literacy is long overdue and in need of serious examination by library practitioners who wish to empower student learning.


A key challenge in the social network community is the problem of network generation - that is, how can we create synthetic networks that match characteristics traditionally found in most real world networks? Important characteristics that are present in social networks include a power law degree distribution, small diameter, and large amounts of clustering. However, most current network generators, such as the Chung Lu and Kronecker models, largely ignore the clustering present in a graph and focus on preserving other network statistics, such as the power law distribution. Models such as the exponential random graph model have a transitivity parameter that can capture clustering, but they are computationally difficult to learn, making scaling to large real world networks intractable. In this work, we propose an extension to the Chung Lu random graph model, the Transitive Chung Lu (TCL) model, which incorporates the notion transitive edges. Specifically, it combines the standard Chung Lu model with edges that are formed through transitive closure (e.g., by connecting a 'friend of a friend'). We prove TCL's expected degree distribution is equal to the degree distribution of the original input graph, while still providing the ability to capture the clustering in the network. The single parameter required by our model can be learned in seconds on graphs with millions of edges, networks can be generated in time that is linear in the number of edges. We demonstrate the performance of TCL on four real-world social networks, including an email dataset with hundreds of thousands of nodes and millions of edges, showing TCL generates graphs that match the degree distribution, clustering coefficients and hop plots of the original networks.


A summary of the literature about the effect of unbalanced supply voltage on induction motors is presented. An experimental study was carried out, where rotor currents of a wound-rotor induction motor were measured under different unbalance conditions with respect to positive and negative sequence voltage magnitudes and phase angles. Rotor overcurrent is not a function of the angle between positive and negative voltage components. Effect of rotor overcurrent is under-estimated by the measured stator overcurrent, and rotor currents are closely similar. The currently used unbalanced-voltage derating factors do not seem to consider rotor winding heating, which is only applicable to squirrel-cage rotors.


Accurate frequency measurements of CO2 transitions around 2 μm are performed by direct frequency-comb Vernier spectroscopy. Measurements of pressure line shifts at the ppb. accuracy level demonstrates the application of comb sources in precision molecular spectroscopy.


We address the problem of supply chain management for a set of fresh and highly perishable products. Our activity mainly concerns forecasting sales. The study involves 19 retailers (small and medium size stores) and a set of 156 different fresh products. The available data is made of three year sales for each store from 2011 to 2013. The forecasting activity started from a pre-processing analysis to identify seasonality, cycle and trend components, and data filtering to remove noise. Moreover, we performed a statistical analysis to estimate the impact of prices and promotions on sales and customers' behaviour. The filtered data is used as input for a forecasting algorithm which is designed to be interactive for the user. The latter is asked to specify ID store, items, training set and planning horizon, and the algorithm provides sales forecasting. We used ARIMA, ARIMAX and transfer function models in which the value of parameters ranges in predefined intervals. The best setting of these parameters is chosen via a two-step analysis, the first based on well-known indicators of information entropy and parsimony, and the second based on standard statistical indicators. The exogenous components of the forecasting models take the impact of prices into account. Quality and accuracy of forecasting are evaluated and compared on a set of real data and some examples are reported.


To explore the effect of dihydroartemisinin(DHA)on the proteins of Giardia lamblia(G.lamblia)trophozoite in vitro,G.lamblia were cultivated axenically with modified TYI-S-33 medium and divided into two groups:the DHA group(group DHA)and the control group(group C).The trophozoites of group DHA were cultivated in medium containing 200μg/ml DHA,while the control group was cultivated in the same medium without DNA.The total protein of trophozoite in each group were extracted and quantified by Bradford method,and then the samples were run by 2D-protein electrophoresis.The electrophoresis gels were stained by silver nitrate.The number and types of protein spots were scanned by image scanning and analyzed by Image Master TM 2D 5.0.Protein spots matching information were obtained and high matching-protein spots were selected for mass spectrometry(MALD-TOF MS)analysis.Results showed that the total protein content(0.6993μg/ml)in group DHA was lower than that of the control group(4.8241μg/ml)after treated with DHA,and the difference is significant statistically(P0.001).About 1 253 protein spots covered with whole gel were identified by two-dimensional electrophoresis.Image scanning analysis showed that the spots intensive and protein expressed highly(proteins are deep in color,clear and bright)in control group.In contrast,about 617 protein spots were recognized in the DHA6h experimental group,and 326 protein spots were recognized in the DHA12h experimental group.The protein expression was lower(light in color and not clear),and reduced significantly.Secondly,the protein spot of 12-30kDa within pI 3.0-7.6 scope in both the control group and group DHA were different significantly in expression,but that in the experimental group decreased distinctly.The majority of protein spots were disappeared,even more,45-60kDa spots almost completely degraded and disappeared conspicuously(6 points remained).The 6 categories of cytoskeletal protein among 14 points in the 80 matched-well protein spots selected for mass spectrometry analysis were identified,while the protein spots disappeared in the experimental group(group DHA).In conclusion,the actions of DHA on Giardia lamblia trophozoites protein were effective,especially on cytoskeletal proteins.


In this study, we proposed a novel human-machine interface (HMI) for robotic manipulator control. The specific target was to adjust the impedance coefficients of the robot controller in real time by measuring the human forearm muscle contractions. We firstly designed a HMI system. Different from the frequently used sEMG technologies, the interface in our study could detect muscle morphological changes within the skin by the electrical impedance tomography (EIT). The sensing front-end was a soft elastic fabric band which was compatible to different arm shapes. With the specific designed sensing hardware and the re-construction algorithms, EIT images indicating forearm muscle shapes were obtained. We then designed a hybrid positon/impedance controller on a UR5 with the impedance coefficients being tuned in real time by the grasp force estimation. A sigmoid regression algorithm was used to map the EIT images to the grasp forces. After implementation of the whole system, two experiments were carried out. The first experiment was the off-line grasp force estimation. With the 1:1 cross validation, an average R2 of $0.83 \pm 0.04$ and an average of the relative root mean square error (RRMSE) of $0.31 \pm 0.10$ across 5 subjects were yielded. The second experiment was the real-time robot control. Trajectory tracking task with dynamic uncertainties were investigated and grasp forces were estimated in real-time. With higher muscle contraction levels, smaller position errors were observed and shorter time was needed to return to the expected trajectory when there were external disturbances. The results proved the feasibility of the new approach on human-robot interaction tasks. Future endeavours will be made to get more promising results.


&NA; An 18‐year experience with the management of the unilateral cleft nasal deformity in 1200 patients is presented. A primary cleft nasal correction was performed at the time of lip repair in infancy; a secondary rhinoplasty was done in adolescence after nasal growth was complete. The technical details of the authors' primary cleft nasal correction are described. Exposure was obtained through the incisions of the rotation‐advancement design. The cartilaginous framework was widely undermined from the skin envelope. The nasal lining was released from the piriform aperture, and a new maxillary platform was created on the cleft side by rotating a "muscular roll" underneath the cleft nasal ala. The alar web was then managed by using a mattress suture running from the web cartilage to the facial musculature. In 60 percent of cases, these maneuvers were sufficient to produce symmetrical dome projection and nostril symmetry. In the other 40 percent, characterized by more severe hypoplasia of the cleft lower lateral cartilage, an inverted U infracartilaginous incision and an alar dome supporting suture (Tajima) to the contralateral upper cartilage were used. Residual dorsal hooding of the lower lateral cartilage was most effectively managed with this suture. This primary approach to the cleft nasal deformity permits more balanced growth and development of the ala and domal complex. Some of the psychological trauma of the early school years may be avoided. Also, because of the early repositioning of the cleft nasal cartilages, the deformity addressed at the time of the adult rhinoplasty is less severe and more amenable to an optimal final result.

Welding technologies are widely applied in all kinds of steel structures. No matter what kind of welding is used, the welding residual stress is always inevitable. So, in this research, a semi- destructive experiment and a numerical simulation are conducted to study the welding residual stress distributions of shear keys in the grouted connection section. The experiment uses the blind hole method on 3 flat-plate specimens of the sleeve section, to measure the welding residual stress distributions of them, which gives an approximate distribution of the real grouted connection section. Based on the experiment, a FEM numerical simulation is performed to estimate welding residual stress distribution. During the numerical simulation, EBD (Element Birth and Death) and Dflux subroutine are applied to maintain a better precision. Through the experiment and simulation, a comparison is done and a good correlation between welding residual stresses was found.


In this article, a nonthermal gliding arc discharge (GAD) was generated in an air flow driven by a 40-kHz alternating current (ac) constant-current electric power supply. The influence of gas flow rate on the discharge characteristics of gliding arc was investigated using electrical diagnostics and fast Fourier transform (FFT) analysis method. The average discharge power, total harmonic distortion rate of arc voltage (THD<inline-formula> <tex-math notation="LaTeX">${_{u}}$ </tex-math></inline-formula>), total harmonic distortion rate of arc current (THD<inline-formula> <tex-math notation="LaTeX">${_{i}}$ </tex-math></inline-formula>), and the resistance of arc were experimentally studied. As the air flow rate increased from 4 to 12 L/min, it was found that the average discharge power of the gliding arc gradually decreased from 407.9 to 187.8 W. However, because of the nonlinear characteristics of the GAD circuit, with air flow rate increasing, both THD<italic>u</italic> and THD<italic>i</italic> linearly increased, while the resistance of arc gradually decreased from 26.3 to 14.1 <inline-formula> <tex-math notation="LaTeX">$\text{k}\Omega $ </tex-math></inline-formula>. Totally, the air flow rate influenced the discharge characteristics of the gliding arc mainly by ruling the average discharge power. Finally, for a better understanding of the discharge characteristics of the gliding arc, a discharge circuit model was further analyzed based on the average discharge power and reactive power.


In the field of social development in urban settings, mediation can be implemented along different lines and can be given different forms. In the Netherlands mediation lies at the heart of a specific kind of social welfare work which was developed during the last fifty years: opbouwwerk (community work). The observation of opbouwwerk practices during the last three decades gives us a chance to show the complexity of the stakes of mediation between conflicting residents or between residents opposed to governmental or semi-governmental bodies. Such an observation also allows us to sort different forms of mediation varying between two major types of mediation, the impartial third party and the committed third party.


The article performs a Critical Study of the Discourse of a fragment of the video "Narconovelas- Movimiento ciudadano #noen3caines" (Garcia & Cartagena, 2013) which gives an account of the citizens' initiative Noen3caines. In this initiative citizens question the media, and what it constitutes as a social response. The general objective is to interpret the social response called Noen3Caines, from the meanings that are proposed in the video analysis. Noen3Caines had concrete effects on the advertisement of the TV series of RCN in Colombia "Tres Caines". At least 13 brands withdrew their advertising thanks to public pressure from the Internet because they considered that his image was not akin to that proposal on television, a matter which has no precedent in the history of the media in Colombia.

The presence of the boundaries imposes severe constraints on the possible Conformal Field Theories (CFTs). Special physical boundary conditions are compatible with CFT and define Boundary Conformal Field Theories (BCFTs). This presentation contains a study of the Yang-Lee edge singularity (YLS) of the two dimensional (2D) Ising model on the infinite strip. At the 2D Ising model's YLS, several potential BCFTs are identified. Based on numerical calculations on an Ising quantum chain at YLS, the measurements are used to identify one of potential BCFTs.


This report describes the results of a study initiated to examine the influence of concrete unit weight on the direct shear transfer across an interface of concretes cast at different times. This type of interface is common with structural precast concrete connections, such as corbels, for which shear friction design provisions are commonly used. Increasing use of lightweight aggregate concretes prompted this investigation to determine the appropriateness of current shear friction design provisions with respect to all-lightweight and sand-lightweight concrete. The experimental investigation included 36 push-off test specimens, each of which was constructed with a cold-joint at the interface shear plane. Test variables included unit weight of concrete (108, 120, and 145 pcf), target compressive strength of concrete (5000 and 8000 psi), and interface condition (smooth or roughened). A constant amount of reinforcing steel was provided across the shear plane. Results suggest that concrete unit weight did not play a significant role in the interface shear strength for the cold-joint specimens in this study. Results were also compared with shear friction design provisions in both the ACI 318 code and the PCI Design Handbook. Shear strengths computed using the coefficient of friction µ approach were conservative for the sand-lightweight and all-lightweight cold-joint specimens in this study. The value of the effective coefficient of friction µₑ computed using the PCI Design Handbook approach was found to be conservative for both roughened and smooth non-monolithic interfaces for each concrete type. Finally, the use of the lightweight concrete modification factor in the calculation for the effective coefficient of friction µₑ was found to be conservative for the sand-lightweight and all-lightweight cold-joint specimens in this study.


L egislative U pdate Major Healthcare Reforms Advance through the California Legislature Douglas Brosnan, MD, JD Department of Emergency Medicine, University of California Irvine School of Medicine Although Gov. Schwarzenegger's healthcare reform plan failed to find a sponsor in the state legislature, the Governor has succeeded in bringing reform to the political fore. Public demand for a change in the way healthcare is delivered in California crosses partisan, ethnic, regional and gender lines. A recent survey by the Public Policy Institute of California found that nine out of ten Californians support healthcare reform; two out of three oppose a physician or hospital tax. 1 Amid this swell of public demand, Assembly Speaker Nunez and Senate Pro Tempore Perata secured approval of major Democratic healthcare reforms in their respective houses of the legislature this month. The Senate's bill was "sent to the Assembly on a 23-16 vote; the Assembly sent its bill to the Senate on a 47-32 vote." 2 In contrast to Gov. Schwarzenegger's plan, neither bill includes a hospital or physician tax. Rather, both bills require employers to help foot the bill, either by providing health insurance for their employees or by paying 7.5% of their payroll expenses into a state-run insurance pool. Both plans also require insurance companies to cover anyone who applies and forces them to spend at least 85% of premiums on medical care. Workers served by the state pool would pay some of the insurance premium -- Perata's bill limits such costs to 5% of income, while Nunez's measure does not specify a cap. Nunez's plan, unlike Perata's, would exempt from the employer mandate those businesses that have been operating for three years or less, employ fewer than two people, or have an annual payroll of less than $100,000. 3 An independent analysis by Jonathan Gruber, an MIT professor of economics, found that both proposals are fiscally viable without a tax on doctors and hospitals while accomplishing expanded coverage to more than two-thirds of the 6.5 million uninsured Californians. 4 A media campaign is now underway in an attempt to shape public opinion and sway legislators. In May, the "Coalition for Responsible Health Care Reform," whose sole member is Blue Cross of California, began a $2 million advertising campaign attempting to scare Californians away from attempts at healthcare reform, drawing comparisons to the energy deregulation fiasco several years ago. 5 In response, Together for Health Care, a group comprised of the California Medical Association, AARP, and various CAL/AAEM Newsletter hospital representatives, labor leaders, and small business interests, began a media campaign including a newspaper and television advertisement campaign that features a Los Angeles emergency physician supporting health reform measures. Also, independent film maker Michael Moore is adding his voice to the mix. He joined in a rally outside the California State Capitol advocating guaranteed healthcare for everyone, proposing a single-payer model. Moore also testified at an unofficial legislative briefing inside the State House. These events also coincide with the release of "Sicko," Moore's new documentary on the nation's broken healthcare system. The film suggests a solution that eliminates for-profit insurance companies and regulates pharmaceutical companies. 6 Other key measures passed legislative hurdles in June. Assembly Bill 1155 (D-Huffman, San Rafael), aimed at addressing widespread abuses by health indemnity plans, passed the Assembly. This bill Requires the Director (Director) of the Department of Managed Health Care (DMHC) to assess an administrative penalty, and require the health plan found to be in violation to pay the provider the amount owed plus interest, when the Director makes a final determination that a health care service plan (health plan) has underpaid or failed to pay a provider in violation of applicable provisions of the Knox-Keene Health Care Service Plan Act of 1975 (Knox- Keene), as specified. 7 This bill seeks to address insurance company abuses by automatically compelling insurers to pay physicians the full amount of underpayment plus interest when DHMC finds that they have been underpaid. Currently, most penalties only require that behavior be corrected going forward, leaving physicians holding unpaid bills with no recourse. Also, Assembly Bill 1554 (D-Jones, Sacramento) would require health plans and health insurers to submit proposed rate increases for annual approval. The Assembly passed the bill Thursday, 43-33. 8 August 2007


A b s t r a c t : This communication presents a model, based on reflection and transmission of plane waves in a dielectric slab, for the estimation of transmission and isolation through building walls and floors, being applied for 60 GHz. The internal reflections phenomenon is negligible for the usual thicknesses of building materials, with the exception of glass, acrylic glass and plasterboard. In the same conditions, the estimation of isolation can be done by using the product of the attenuation coefficient by the wall thickness, and it is seen that at least a value of 20 dB is obtained. As a general conclusion, only glass and plasterboard are not effective in isolating cells with the same frequency group.


In the prospect to discuss the construction of fuzzy gravity theories based on the gauge-theoretic approach of ordinary gravity, in the present article we review first the latter in three and four dimensions and then, after recalling the formulation of gauge theories on noncommutative spaces, we present in detail the construction of fuzzy gravity theories in three and four dimensions, as matrix models.


The objective of this paper is two-fold: firstly, we develop a local and global (in time) wellposedness theory of a system describing the motion of two fluids with different densities under capillary-gravity waves in a deep water flow (namely, a Schrödinger-Benjamin-Ono system) for lowregularity initial data in both periodic and continuous cases; secondly, a family of new periodic travelling waves for the Schrödinger-Benjamin-Ono system is given: by fixing a minimal period we obtain, via the implicit function theorem, a smooth branch of periodic solutions bifurcating of the Jacobian elliptic function called dnoidal, and, moreover, we prove that all these periodic travelling waves are nonlinearly stable by perturbations with the same wavelength.


When a positive detection of a narcotic occurs during the search of a vessel, a decision has to be made whether further intensive search is warranted. In terms of unwarranted delays of vessels and possible property damage, the accuracy of the analytical determination is very important. Analytical accuracy becomes critical when the data may be used in court actions as evidence. For this purpose, the U.S. Coast Guard has been investigating several confirmatory ion mobility spectrometry (IMS) field methods for the detection and identification of cocaine. This paper presents the findings of our investigations on the use of catalytic pyrolysis and base hydrolysis as confirmatory methods. The catalytic effects of various metals on the pyrolysis reaction are reported. In addition, the effects of several different ion mobility spectrometer sample transfer mediums and varying laboratory conditions on the base hydrolysis of the cocaine molecule are also be reported. BACKGROUND The U.S. Coast Guard (USCG) R&D Center has conducted extensive tests and evaluations (T&E) of commercially available contraband detection systems in both laboratory and field environments since 1991. The objective of these T&E studies was to determine if commercially available illicit drug detection systems could be effectively used in the search of maritime vessels for the presence of smuggled narcotics. Criteria used in selecting appropriate systems for test and study included: minimal sample preparation and pretreatment; speed of sample analysis; low nanogram narcotic detection levels; portability; ease of operation; and affordability. As the amount of laboratory and field T&E data increased, with respect to system performance under actual field situations and the effects of natural environmental backgrounds on analytical results, the accuracy of a positive 229 https://ntrs.nasa.gov/search.jsp?R=19950026862 2019-08-14T03:35:07+00:00Z


This work analyses, over and beyond the Brazilian war songs during the Second World War, the Brazil (itself) in the war songs. It uses the plays created by the FEB and FAB combatants in Italy, the music revealed by the military musicians and by radio transmissions of FEB as well as the hymns that stimulated the patriotic actions of Brazilians throughout the country. Also, commercial records, launched during the years that the country effectively participated in the conflict (1942-1945), illustrating the Brazilian viewpoint during this particular situation of international rearrangement. All these songs have passed through the sieve of Brazilian Critical Theorry, finding in the parody the most common tool at the time for show the social structures in music.


This article describes a re-analysis of a national study of instructional practices in seventh- and eighth-grade science classes. Responses from a subset (n = 81) of Christian-school teachers taken from the original study population (n = 543) was analyzed to determine what instructional practices predominated in Christian-school science classes. Results indicate the use of a variety of both teacher- and student-centered instructional approaches by science teachers in Christian schools.


The purpose of this paper is to sort out the theoretical origin of common prosperity, grasp the connotation of common prosperity under the new historical orientation, and clarify the logical premise of realizing common prosperity. The research methods of this paper are textual research and retrospec-tion of the history of thought. Common prosperity is an essential requirement of socialism and an important feature of Chinese-style modernization, enabling the people to enjoy both material and intellectual prosperity. Common prosperity is for all people, comprehensive, co-building, gradual. From Chinese traditional culture, to Utopian socialism, scientific socialism, and then to socialism with Chinese characteristics, it is helpful to grasp the theoretical logic of common prosperity to clarify the historical development of common prosperity. Promoting common prosperity also has its internal logical premise: the political premise of realizing common prosperity is to adhere to the leadership of the Party, the material basis of realizing common prosperity is highly developed productive forces, and the spiritual and cultural basis of realizing common prosperity is the spiritual life of the people and the community consciousness.


Canada remains a country of a few dense urban concentrations and a large number of far flung medium and smaller communities. Our greatest challenges in EM today are overcrowding and understaffing. Crowding is almost universal; staffing is most difficult in the medium and smaller community settings, many of them not far from major centres. It is difficult to discern how eliminating our CFPC training route would help with either challenge. AbuLaban makes a comparison between emergency care and obstetrical care. It isn't a bad comparison. Many family doctors deliver babies in communities with no obstetricians. Some family doctors have extra training and do a great deal of obstetrical care, often side by side with obstetricians. They teach and do research and contribute to policy. They have demonstrated superior outcomes to their obstetrical colleagues in some populations in C-section and episiotomy rates. No one would suggest we do without obstetricians, but family physicians with an interest in obstetrics make significant contributions and provide a different approach and perspective based on their training and clinical experience. Twenty-five years into a grand experiment, we should be celebrating our suc

The unit cell is triclinic, space group P-1 with cell dimensions of a = 4.1519(10) Å, b = 4.7055(10) Å, c = 53.555(4) Å, α = 89.473(15)°, β = 87.617(5)° and γ = 76.329(5)°. The structure is characterized by an 8-membered ring dimer of Ag atoms and carboxyl groups joined by four-member Ag–O rings with fully extended zigzag side chains, giving rise to one-dimensional chains along the b-axis.


Dynamic growth patterns of developing Asia will continue to make strong impressions in world commodity markets. Driven by rapid income growth and economic development, developing Asia has surfaced as a major demand force behind the price dynamics of primary commodities. The region's economic growth and development has been tightly associated with rapid industrialization, urbanization, and massive infrastructure investments, which are all resource‐intensive. These trends are set to intensify as Asia's mammoth economies emerge. The paper provides an overview of Asian influence in world commodity markets and examines its changing patterns. It also attempts to quantify the impact of the rapidly growing Asian economy on long‐term resource utilization, using a General Equilibrium Model for Asian Trade to project regional growth scenarios. The model captures long‐run equilibrium tendencies in product and factor markets for the use of natural resources. The estimated results point to fundamental changes in market...

Postnatal depression correlates with postpartum weight retention, and dysregulated cortisol metabolism is evident in depressed individuals. Cortisol metabolism, BMI and metabolic phenotype are robustly associated, but the role of cortisol metabolism in postnatal mental health and weight loss has never been examined.


Single-day snow covered area (SCA) products are incomplete and often inadequate representations of ground conditions due to short term variations in cloud cover, snow cover, and sensor geometry. To mitigate these effects, we developed a by-pixel filtering algorithm to produce relatively cloud-free SCA products based on 16 days of MODIS imagery. To be positively identified as SCA, a pixel must be snow-covered in the two most recent, cloud-free scenes in the 16-day period. We applied this methodology to two single-day MODIS fractional snow cover products over the period of record and compared the outputs to the respective single day products and to historical snow assessment reports from the Cold Regions Research and Engineering Laboratory (CRREL). The CRREL reports were generated and quality-controlled by an analyst and are treated as ground truth. In general, algorithm outputs agree strongly with the CRREL reports both temporally and spatially. Discrepancies were most often observed early in the season in relatively low elevation areas and are likely attributable to transient SCA being removed by the algorithm. The generated products are less temporally variable than their respective single day inputs and are essentially cloud-free, making them more reliable indicators of ground conditions on any given day.


A central difference between 'ritual failure' and 'mistake' is that failure refers to the efficacy of a ritual whereas a mistake refers to the procedural performance and as such is closely related to competence and agency. However, both notions are contingent: rituals are actions and are, as any other human action, never free of contingencies. While the contingencies or 'risks' lying in a ritual's performance is concentrated on Mistakes, Procedural Errors and Incorrect Performances", the contributions to this chapter mainly focuses on the uncertainty of the outcome of a ritual, that is, a ritual's efficacy. However, 'efficacy denotes a wide range of phenomena: the effects of a ritual postulated on a doctrinal level, its social consequences, the fulfilment of individual expectations, empirically detectable effects, unexpected outcomes, and so on. The case study presented in this chapter clearly shows that a ritual's efficacy cannot be reduced to one of these aspects.Keywords: ritual efficacy; social consequences


Federated learning has attracted increasing attention with the emergence of distributed data. While extensive federated learning algorithms have been proposed for the non-convex distributed problem, the federated learning in practice still faces numerous challenges, such as the large training iterations to converge since the sizes of models and datasets keep increasing, and the lack of adaptivity by SGD-based model updates. Meanwhile, the study of adaptive methods in federated learning is scarce and existing works either lack a complete theoretical convergence guarantee or have slow sample complexity. In this paper, we propose an efficient adaptive algorithm (i.e., FAFED) based on the momentum-based variance reduced technique in cross-silo FL. We first explore how to design the adaptive algorithm in the FL setting. By providing a counter-example, we prove that a simple combination of FL and adaptive methods could lead to divergence. More importantly, we provide a convergence analysis for our method and prove that our algorithm is the first adaptive FL algorithm to reach the best-known samples O(epsilon(-3)) and O(epsilon(-2)) communication rounds to find an epsilon-stationary point without large batches. The experimental results on the language modeling task and image classification task with heterogeneous data demonstrate the efficiency of our algorithms.


Introduction to Cost–Benefit Analysis is intended as a graduate and advanced undergraduate textbook. Nevertheless, economists and other practitioners involved in the economic evaluation of projects will also find the book extremely useful.


The elastic properties of graphite/epoxy composites with three-dimensional interlock weave reinforcement have been measured over length scales somewhat greater than the characteristic length of the weave pattern. Orientation averaging models similar to those developed elsewhere over the last twenty years provide estimates of elastic constants that are in fair agreement with the experimental data. However, in-plane Young's moduli are consistently too high and properties related to the through-thickness reinforcement show considerable scatter. Most of the discrepancies can be attributed to waviness and other geometrical irregularities in nominally straight tow segments. Much improved agreement with in-plane properties is obtained by measuring and accounting for the out-of-plane waviness of in-plane tows. Other observed distortions of in-plane tows and irregularity in through-thickness tows are very difficult to quantify experimentally. There results a significant and apparently unavoidable uncertainty in predictions of properties that depend strongly on the through-thickness reinforcement. Nevertheless, the utility of orientation averaging models in applications where the in-plane properties are paramount is clearly verified.

Received: February 13, 2017 Revised: March 11, 2017 Accepted: March 20, 2017 Objectives: The purpose of this study is to investigate how the psychological and mental tendencies manifested in the Sasang Constitution are reflected in an objective personality test, MMPI-2. Methods: The survey was conducted on 101 Korean medical students to investigate the relationship between the Sasang Constitution and MMPI-2. Results: Soeumin showed higher scores in the Hs, Pt, RC1 and RC3 than Taeumin and showed higher scores in the D, Si, RC2, R, MAC-R and INTR than Soyangin. Soeumin showed higher scores in the ANX, OBS, and HEA and showed lower scores in the Es and GM than other Constitutions. Soyangin showed the higher scores in the AGGR than Soeumin and showed the higher scores in the RC9 than other Constitutions. Soyangin showed the lower scores in the SOD and Taeumin showed the lower scores in the ASP than other Constitution (p<.05). Conclusions: MMPI-2 contains items that distinguish the characteristics of Soeumin, Soyangin, and Taeumin and it is therefore useful to employ it to obtain basic data for analyzing oriental psychopathology.


Internal combustion engines are generally speaking mechanical devices but have benefitted tremendously from electronic controls. The electronic implementation of fuel injection and spark ignition on an older single-cylinder JAP engine through the use of a programmable Engine Control Unit (ECU) is discussed in this work. Furthermore the additional electronics required for water injection and boost control that were not supported by the programmable ECU are detailed. The injection of water into the Spark Ignition (SI) engine was the main objective of this study but the solution for this task through the use of electronics and LabView provided a robust and flexible system whereby the whole range of parameters could be explored. The engine was electronically controlled by the ECU through the sensing of 36 teeth that were machined in the dynamometer coupling and by having the cam sensor triggered by the maximum lift of the tappet of one of the valves. Water injection electronic circuitry was designed and built from scratch. The variable duration water injection pulse was generated by a 555 timer IC in Monostable (configuration) mode that was triggered every two engine revolutions by the fuel pulse. The duration of water injection per cycle in milliseconds was recorded by the ECU through the use of a dual potentiometer that controlled both the RC value for the 555 timer and also generated a voltage that varied linearly with water pulse duration for data logging by the ECU. Boost control of the engine from the laboratory compressed air supply was first tried to be solved by mechanical means namely manual control, an external wastegate (used as a proportional valve) and also different sized pressure regulators, however these attempts were unsuccessful. A very straightforward but ultimately functional solution was the use of an ON/OFF solenoid valve that opened compressed air (6 bar nominal) to a large (approx. 1m3) tank that fed the SI engine. The ON/OFF control was performed through LabView and a specifically built solenoid driver circuit. The control of air temperature into the SI engine was also electronically controlled through ON/OFF control from LabView which controlled the water temperature of a charge-air heat exchanger. These systems were integrated together and performed as desired to test all desired water injection durations, boost levels, air inlet temperatures, spark timing and fuel quantity.


A standing wave thermoacoustic prime mover (TAPM) has been succesfully designed, constructed, and evaluated. It consists of a resonator with length of 128 cm, a stainless-steel wire-mesh stack with 14 mesh number, two heat exchangers, and air at atmospheric pressure as the working gas inside the resonator. The stack is placed inside the resonator near one of its closed-ends and has 4 cm length. The hot and ambient heat-exchangers are attached at each end of the stack to provide a large temperature gradient along the stack which is required for generating acoustic energy. An electric heater with maximum power of 400 W is used to supply thermal energy to the TAPM. The temperatures and dynamic pressures are measured by using type-K thermocouples and pressure transducers, respectively. We evaluated the prime mover by experimentally investigating the influence of heat input power on the onset temperature difference, time to reach the onset condition, sound frequency, and sound pressure amplitude. It was found ...


The three dimension physico-mathematical model was established for the integrated planar solid oxide fuel cell (IP-SOFC) with the couples of multi components flow of reacting gas, heat transfer and electro-chemical process in order to reveal the inherent multi-scale effect of gas distributing duct and the porous support layer, and also, the microscale effect on the transport process in fuel cell. The mutual influences between heat transfer and chemical components transport were included in the model. In addition, the thermal effect of chemical reactions and its influences on polarizations of fuel cell were considered. And also, besides the Darcy diffusion, the Knudsen diffusion in the sub-microscale structure of the porous support is taken into consideration. Numerical simulation was employed to solve the model, by which, the output performance and polarization characteristics of a single cell were analyzed and compared for electrolyte-supported, anode-supported and cathode-supported SOFC, respectively. The present model was also validated comparing with the experimental data.Copyright © 2010 by ASME


This paper presents an analytical method for determining the power losses in the three-phase gas-insulated transmission line (i.e., high-current busduct) of circular crosssection geometry. The mathematical model takes into account the skin effect and the proximity effects, as well as the complete electromagnetic coupling between phase conductors and enclosures (i.e., screens). Apart from analytical calculation, computer simulations for high-current busduct system power losses were also performed with the aid of the commercial FEMM software, using two-dimensional finite elements.


Democracy is based on the principle of the majority able to choose who leads them in a free and fair context devoid of external interference and political influence. The right to elect a wrong candidate is even part of democracy. The law cannot regulate the legitimate choices that the democratic free will is entitled to make. It chooses what it will. It rejects what it will not choose, or else the democratic free will ceases to be what it fundamentally ought to be, namely "free". Vote trading is a concept in the Nigerian democratic experience. The issue of vote-trading has been in Nigeria's democracy since its inception but became prominent during the present democratic dispensation. Vote buying has been serving as a clog in the wheel of free choice which is the hallmark of a democracy. Unfortunately, not all people that being influenced by vote-buying know what is going on. Some people indulge in the act of vote-trading unknowing. This study which is mainly based on literature and conceptually looked at the influence of vote trading on voter's free choice, the factors that influenced both vote buying and selling, and how it can be curbed. Consequently, past literature, like journals, books, and other publications on vote-trading were considered in this study.


According to the structure characteristic of forging manipulator jaw,the jaw's gripping process was separated into the clamping condition to make the plastic deformation extrusion mark on the workpiece and the gripping condition when supporting the gravity and heavy torque of the workpiece and performing the operating action to do a theoretical analysis on jaw's gripping force.The research results indicate that the gripping force is affected by the extrusion and the gripping force of the forging manipulator should be determined by the force of the clamping condition.Based on it,the factors affecting the jaw's clamping force were analyzed,and the conditions for the optimization of the jaw's structure were provided.


Interfacial exchange coupling is known to improve the permanent magnetic performance (i.e., maximal energy product) in composites of magnetically hard and soft particles. The prevailing strategy, employed in a plethora of compositions, consists in maximizing the coupling between the hard and soft phases and optimizing material parameters such as particle size or phase composition. In CoFe2O4–FeCo nanocomposites, it is experimentally shown that interparticle uncoupling in combination with the sizes of the soft phase grains below the single‐domain threshold leads to enhanced magnetic properties at room temperature, while maximizing exchange coupling implies a collapse in coercivity and hence in the maximal energy product. The results are corroborated by micromagnetic calculations and the origin of the exchange‐induced softening is discussed. It is emphasized that engineering interfaces in order to optimize, rather than maximize, the degree of exchange coupling are a necessary requirement to improve the energy product in nanocomposite magnets and to successfully develop advanced rare‐earth‐free permanent magnets.

In order to solve the problem of peak shaving capacity in power system caused by high permeability of renewable energy, this paper proposed a cascaded hydropower "Virtual pumped storage power station" scheduling method. The "Virtual pumped storage power station" model of cascade hydropower stations is established by studying the coupling relationship between each cascaded hydropower stations, simulating the operation of pumped storage power stations from both hydraulic and electrical aspects. Under the constraints of cascaded hydropower stations, the objective function of peak shaving power of "virtual pumped power station" is constructed and figured out. The simulation results prove that the cascaded hydropower scheduling from this method is able to significantly improve flexibility and economy of cascaded hydropower, and taps the peak shaving potential of cascaded hydropower sufficiently. Keywords—cascaded hydropower; virtual pumped storage; real-time scheduling


Exact solutions to diffraction problems in wave optics are scarce though strongly demanded for accurate knowledge of electromagnetic fields in the immediate vicinity of scatterers. Here, we obtain and analyze an exact analytical solution for plane-wave diffraction at a lateral junction of two-dimensional (2D) conductors with dissimilar surface conductivities. We find that the junction near fields possesses a dipolelike radiative component and 2D surface-plasmon polaritons launched by the edge. We show that a junction between a perfect metal and an ohmic 2D conductor enhances the local absorbance, which is the ratio of absorbed power density and light intensity. It reaches a universal value of 200% near the 2D edge at normal incidence, independent of absorbance in the bulk. A junction between metal and a 2D conductor also acts as an efficient coupler between photons and 2D plasmons. Its amplitude conversion efficiency demonstrates an unbounded growth with increase in 2D impedance. Our results set the fundamental limits for field enhancement by edges and should change the strategies for design of subwavelength radiation detectors.


Abstract In this article, we propose a novel Simultaneous Localization and Mapping (SLAM) method by using a sampling-based approach. FastSLAM is well-known approach as a sampling-based SLAM method. FastSLAM utilizes a theorem that map errors are decidable under a sample of trajectories. From this theorem, FastSLAM samples many trajectories and maps to find a minimum error map. However, in case of constructing a large-scale grid map, FastSLAM becomes unuseful since the method requires huge memory to generate many grid maps. Our proposed method requires only one map that is deformable corresponding to a trajectory. In order to find a minimum error map, our method only generates trajectories. Our method enables construction of a minimum error map by little memory in comparison with original FastSLAM. Experimental results demonstrate our method is able to construct a large-scale 3-D grid map by low memory usage in comparison with original FastSLAM.


Open knowledge communities (OKCs) are computer supported collaborative learning environments that provide opportunities for social knowledge construction, collaboration, participation and communication for ubiquitous learning and informal learning. However, with the rapid expanding of learning content resources and users, it is difficult for learners to find the right persons they need as knowledge experts and learning peers in OKCs using traditional search engines. To solve this problem, the paper presents a novel intelligent framework for finding the right experts and learning peers based on social knowledge network. After describing the architectural details of the framework, the authors elaborate on the intelligent framework design, the work principle, and mechanism of each module. Finally,the authors conclude by showing the learning application scenarios of this intelligent framework.

The decision about which servers to dispatch to which customers is an important aspect of service systems. This decision is complicated when servers must be equitably---as well as efficiently---dispatched to customers. In this paper, we formulate a model for determining how to optimally dispatch distinguishable servers to prioritized customers given a set of equity constraints. These issues are examined through the lens of emergency medical service EMS dispatch, for which a Markov decision process model is developed that captures how to dispatch ambulances servers to prioritized patients customers. It is assumed that customers arrive sequentially, with the priority and location of each customer becoming known upon arrival. Four types of equity constraints are considered---two of which reflect customer equity and two of which reflect server equity---all of which draw upon the decision analytic and social science literature to compare the effects of different notions of equity on the resulting dispatching policies. The Markov decision processes are formulated as equity-constrained linear programming models. A computational example is applied to an EMS system to compare the different equity models.

Assistive technologies (AT) play an important role in the lives of people with disabilities. Most importantly, they allow individuals with severe physical disabilities become more independence. Inherent abilities of the human tongue originated from its strong representation in the motor cortex, its direct connection to the brain through well-protected cranial nerves, and easy access without a surgery have resulted in development of a series of tongue-operated ATs that tap into the dexterous, intuitive, rapid, precise, and tireless motion of the tongue. These ATs not only help people with tetraplegia as a result of spinal cord injury or degenerative neurological diseases to access computers/smartphones, drive wheelchairs, and interact with their environments but also have the potential to enhance rehabilitation paradigms for stroke survivors. In this paper, various types of tongue operated ATs are discussed based on their working principles and task based performances. Comparisons are drawn based on widely accepted and standardized quantitative measures, such as throughput, information transfer rate, typing speed/accuracy, tracking error, navigation period, and navigation accuracy as well as qualitative measures, such as user feedback. Finally, the prospects of using variations of these versatile devices to enhance human performance in environments that limit hand and finger movements, such as space exploration or underwater operations are discussed.


This talk brie"y reviews the subject of "uid "ow through disordered media. In particular, we focus on the sorts of considerations that may be necessary to move statistical physics from the description of idealized "ows in the limit of zero Reynolds number to more realistic "ows of real "uids moving at a nonzero velocity, where inertia e4ects mean that dangling ends are explored and the backbone is not entirely explored by the "uid. We discuss several intriguing features, such as the surprisingly sharp change in behavior from a localized to delocalized "ow structure (distribution of "ow velocities) that seems to occur at a critical value of Re which is orders of magnitude smaller than the critical value of Re where turbulence sets in. c © 2001 Published by Elsevier Science B.V.


Objective:To evaluate the feasibility of displaying pulmonary vessels by 3.0 T magnetic resonance with LAVA sequence. Materials and methods:59 patients who were suspected of intrathoracic lesions underwent GE 3.0 T HD MR examination. After conventional axial T1W(FSE,TR/TE 833/13.4ms) and T2W(SSFSE,TR/TE 2000/98.7ms) imaging,coronal LAVA sequence(TR/TE,2.3/1.1ms,flip angle 12?,FOV=35×35cm,slice thickness,1.4mm) was used to reconstract multiphases(pulmonary arterial phase,pulmonary venous phase,aortic phase) post-contrast-enhanced scanning. The MIP technique was used to reconstruct pulmonary vessels at the workstation(ADW 4.3) . The visibility of branches of pulmonary arteries and veins and the signal-to-noise ratio of pulmonary parenchyma were analyzed by two experienced thoracic-radiologists. was analyzed. Results:In 58 cases(98%) and 53 cases(90%) third-and fourth-order pulmonary arterial branches were observed. In 30 cases(51%) fifth-order pulmonary arterial branches was observed. Conclusion:3.0 T MR with LAVA sequence could display the branches of pulmonary vessels distinctly and provide high-quality vascular morphologic detail.


The interconnectedness of markets is a useful measure of risk and therefore an indicator of economic stability. In this paper, the interconnectedness among housing markets in different metropolitan areas was analyzed. Interconnectedness between the housing market and other markets were also calculated. In regional studies, West Coast housing markets were found to be the most influential on housing markets elsewhere. Interestingly, overall connectedness across regions steadily increased prior to the subprime mortgage crisis, representing a systematic risk increase. When analyzing diverse markets in relation to the housing market, the stock market was found to have the highest interconnectedness, suggesting that financial health of stock market depend on financial health of housing market. The increased systematic risk due to high housing market interconnectedness coupled with the interdependence between the stock market and the housing market were key indicators of the subprime mortgage crisis. Such measures should be monitored in the future to avoid a similar economic disaster.


This paper presents progress in building environment models for the CMU Navlab, an autonomous vehicle for on-road and cross-country navigation. We present robust object tracking from sequence of range images and building and updating 3-D object representations. Tracking uses object prediction from one image to the next to accurately compute object locations. Object representations are built by merging sets of points from individual images into a single set in an object-centered coordinate frame. The sparse set of points is then segmented into shapes yielding compact and general object representations. The object representation may be used for landmark recognition during a map-based navigation mission.


In the ongoing quest for energy production by nonconventional methods, energy conversion by vacuum and solid-state thermionic emission devices is one of the potentially efficient pathways for converting thermal energy directly into electrical power. The realization of practical of thermionic energy conversion devices strongly depends on achieving low work function materials, which is thus far a limiting factor. In an attempt to develop a new low work function thermionic material, this work reports thermionic emission energy distributions (TEEDs) from nanocrystalline diamond (NCD) films in the temperature range from 700 to 900 °C that reveal a consistent effective work function of 3.3 eV. The NCD films also exhibit emission peaks corresponding to higher work functions as indicated by shifts in their energy position and relative intensity as a function of temperature. These shifts thus appear to be related to instabilities in the NCD's surface chemistry. The analysis of these data yields information on the ...


Objective To explore the value of two-dimensional ultrasound speckle-tracking imaging(STI) in assessing the left ventricular torsion(LVtor) in patients with apical hypertrophic cardiomyopathy(AHCM).Methods Thirty-four patients with AHCM and 21 healthy volunteers underwent two-dimensional echocardiography.High frame rate two-dimensional images of left ventricular short-axis views at the levels of mitral annulus and apex were obtained.Peak rotation(Prot) and the time to Prot,peak rotation velocity on basal and apical plane in left ventricular short-axis views,the peak twist(Ptw) and time to peak twist,half time of untwisting(HTU) were measured using two-dimensional strain software while twisting rate(Untw R) was calculated.All the above indices were compared between patients and healthy volunteers.Correlation was analyzed between HTU and E,A,E/A ratio.Results Compare with healthy volunteers,Prot and time to Prot and peak rotation velocity on apical plane in AHCM significantly increased,so did Ptw and peak rotation velocity of left ventricular(all P 0.05).HTU delayed with the Untw R and peak untwisting velocity decreased in the AHCM group(all P 0.05).There was negative correlation between HTU and E/A ratio in patients with AHCM.Conclusion When the left ventricular systolic function maintained normal in patients with AHCM,the peak rotation on apical plane and the LVtor increased with Untw R decreased.STI can sensitively evaluate the function alteration of myocardium in patients with AHCM.


The amount of radiation delivered to the testes in x-ray examinations must be kept as small as possible, consistent with the clinical needs of the patient. Important means of accomplishing this are the elimination of unnecessary examinations and careful coning of the x-ray beam; but, even when coning is carefully done, the testes receive a relatively large dose during the making of such films as those of the pelvis. For several months we have been employing improvised shields, and recently our experimental shop has produced the instrument illustrated in figure 1. It consists of a ½-in.-thick Bakelite base with felt cemented to its undersurface. Rising from this base is a ¾ by ¾ by 15 in. hollow steel post on which rides a bracket that carries the shield. Within the post is a 1-lb. lead weight attached to the bracket by light cable chain passing over sheaves at the upper

In recent years unstructured text has flooded on the web and today it is a trend to comments, give feedback, share experiences toward products, articles, social issues, multimedia web documents etc. Most of the online social, as well as, commercial platform have started to provide separate space for user reviews in the form of natural text. This electronic data is becoming very crucial and popular in decision making. Nowadays, sentiment analysis is not a onetime put effort rather it is more important to know about different aspects mentioned in the user comments. Aspect-term extraction is one of the critical subtasks in aspect-based sentiment analysis. Most of the aspect extraction approaches are the domain or context-dependent. In this paper, an approach is proposed to identify prominent aspects using contextual and domain-specific information. The study and experimental results on different categories of aspects are investigated on standard review data-sets.

The research of dynamic plant layout problem (DPLP) is to find the optimal layout scheme within multiple periods of production, with the increasing scale of calculation, the efficiency of the traditional centralized algorithm may be decreased. In this paper, we proposed a decentralized genetic algorithm (DGA) which combines genetic algorithm (GA) with decentralized optimization technology. Simulation experiments are carried out to compare the decentralized genetic algorithm with the centralized one, and the result shows that the decentralized method is better than the latter at convergence rate and optimization result. On the other way, the decentralized algorithm is a parallel computing technology, so it can improve computational efficiency especially in high-complexity systems.
