SCSQ (Scalable Stream Query processor) is a data stream management system (DSMS) that allows different kinds of distributed high-volume infinite streams to be queried. The current Java interface to SCSQ usesC libraries to communicate between Java and a SCSQ server. Therefore, a pure Java client-server interface to SCSQ is needed. Unlike regular databases, DSMS can process queries over infinite streams. Such continuous queries (CQs) are running until they are explicitlyterminated. The interface must be able to process infinite scans of continuous query results. This master thesis implements a pure Java client-server interface to SCSQ which can handle CQs.

L’un des buts de l’Ingénierie Dirigée par les Modèles (IDM) est de considérer les modèles comme des éléments productifs pour le développement d’applications. Dans cette optique, une nouvelle tendance concerne les modèles exécutables où un modèle produit en phase de conception est réutilisé en tant que tel en phase d’exécution grâce aux interpreted Domain-Specific Modeling Language (i DSML) qui sont interprétés par un moteur d’exécution. Cette façon de procéder permet de gagner du temps lors du développement d’un logiciel et est par conséquent moins coûteux. D’autre part, les logiciels peuvent être dotés de capacités adaptatives. Ces applications adaptatives sont généralement confrontées à un contexte qui est plus ou moins connu et susceptible de changer au cours de l’exécution et auquel elles vont devoir faire face en modifiant leur comportement dynamiquement, c’est-à-dire sans interruption de service. De telles adaptations dynamiques et automatiques sont censées éviter une phase de maintenance onéreuse pour le logiciel. Nous avons donc d’un côté les i DSML qui permettent de réduire les coûts de développement d’une application et de l’autre côté l’adaptation logicielle qui permet de réduire les coûts de maintenance d’un programme. Dans cette thèse nous souhaitons prendre le meilleur des deux mondes en fusionnant les deux idées. Le résultat revient in fine à directement adapter l’exécution d’un modèle via des i DSML adaptables. Pour cela, nous proposons une caractérisation des i DSML adaptables, la définition du concept de famille pour gérer l’adaptation des i DSML, puis la création d’un langage exécutable d’orchestration dédié à l’adaptation, aboutissant ainsi au fait particulier d’adapter un i DSML par un autre i DSML. Enfin, un prototype à base de deux moteurs d’exécution est proposé avec son implémentation en Java/EMFOne of the goals of Model-Driven Engineering (MDE) is to treat models as productive elements for software development. From this point of view, a new trend is about executable models where a model that is produced at design time is reused as such at runtime through interpreted Domain-Specific Modeling Languages (i DSMLs) that are interpreted by an execution engine. This way to proceed allows to save time during the software development and consequently is more cost-effective. On the other hand, software can provide adaptive capabilities. These adaptive applications are often facing a context which is more or less known and which may change during the execution and they will address these various situations by modifying dynamically their own behavior, i.e. without any service disruption. Such dynamic and automatic adaptations ought to avoid a too expensive maintenance stage for the program. We have on one hand the i DSMLs that allow to decrease the development costs of a program and on the other hand the software adaptation that allows to decrease the maintenance costs of an application. In this thesis, we must succeed in having the best of both worlds by merging these two ideas. The result is ultimately to directly adapt the model execution through adaptable i DSMLs. To this end, we propose a characterization of adaptable i DSMLs, the definition of the family concept to manage adaptation of i DSMLs, then the creation of an executable orchestration language for adaptation, thereby leading to the fact that an i DSML is adapted through an other i DSML. Finally, a prototype based on two execution engines is proposed with its implementation in Java/EMF

Powering spacecraft with electric propulsion is becoming more common, especially in CubeSat-class satellites. On account of the risk of spacecraft interactions, it is important to have robust analysis and modeling tools of electric propulsion engines, particularly of the plasma plume. The Navier-Stokes equations used in classic continuum computational fluid dynamics do not apply to the rarefied plasma, and therefore another method must be used to model the flow. A good solution is to use the DSMC method, which uses a combination of particle modeling and statistical methods for modeling the simulated molecules. A DSMC simulation known as SINATRA has been developed with the goal to model electric propulsion plumes. SINATRA uses an octree mesh, is written in C++, and is designed to be expanded by further research. SINATRA has been initially validated through several tests and comparisons to theoretical data and other DSMC models. This thesis examines expanding the functionality of SINATRA to simulate charged particles and make SINATRA a DSMC-PIC hybrid. The electric potential is calculated through a 7-point 3D stencil on the mesh nodes and solved with a Gauss-Seidel solver. It is validated through test cases of charged particles to demonstrate the accuracy and capabilities of the model. An ambipolar diffusion test case is compared to a neutral diffusion case and the electric field is shown to stabilize the diffusion rate. A steady state flow test case shows the simulation is able to stabilize and solve the electric potential for a plume-like scenario. It includes additional features to simplify further research including a comprehensive user manual, industry-standard version control, text file inputs, GUI control, and simple parallelism of the simulation. Compilation and execution are standardized to be simple and platform independent to allow longevity of the code base. Finally, the execution bottlenecks of linking particles to cells and particle moving were removed to reduce the simulation time by 95%.

Este estudo tenciona discutir o problema da conceituação das doenças mentais, a partir dos DSMs e dos diferentes paradigmas que os embasaram. O DSM (manual estatístico e diagnóstico de transtornos mentais) é um manual, de influência internacional, para profissionais da saúde mental, que lista diferentes categorias de transtornos mentais, de acordo com a Associação Psiquiátrica Norte-Americana. Desde a sua primeira publicação, em 1952, já foi submetido a cinco revisões (DSM II, DSM III, DSM III-R, DSM IV e DSM IVTR). Escolhemos a categoria diagnóstica da depressão, objetivando realizar um rastreamento
conceitual, desde o DSM II - modelo até então marcado pela psicanálise, depois ressaltando o DSM III, que, em 1980, promove uma mudança de paradigma no conhecimento psiquiátrico, ao apresentar um modelo que se propõe descritivo e ateórico até o DSM IV-TR. Dessa
perspectiva, são assinaladas algumas considerações e pontos de discussão entre a chamada psiquiatria biológica e a psicanálise, no que diz respeito às suas respectivas influências na forma de entender o diagnóstico psiquiátrico, enfatizando a categoria diagnóstica da depressão.This study intends to discuss the issue of categorizing mental disorders, considering DSMs and its paradigms. The Diagnostic and Statistical Manual of Mental Disorder (DSM) is a handbook, used worldwide, for mental professionals that lists different categories of mental disorder, according to the American Psychiatric Association. The DSM has gone through five revisions (DSM II, DSM III, DSM III-R, DSM IV e DSM IV- TR) since it was first published in 1952. Electing the concept of depression, this study analyses its diagnosis criteria from DSM II, a psychoanalytic influenced manual to DSM IV-TR, with an emphasis upon DSM III which, in 1980, represents a turning point in psychiatric paradigms, intending to be not theoretical and descriptive. From this perspective, the intention is to outline some considerations and discussions between the so-called biological psychiatric and the psychoanalytic theory, according to its influences in the psychiatric diagnosis understanding, emphasizing the category of depression.

Aerothermodynamic investigations of hypersonic re-entry vehicles provides crucial information to other key disciplines as structures and materials, assisting the development of efficient and lightweight thermal protection systems (TPS). Under the transitional flow regime, where chemical and thermal nonequilibrium are predominant, the most successful numerical method for such studies has been the direct simulation Monte Carlo (DSMC) numerical technique. In the present work, the solver dsmcFoam has been benchmarked against experimental, numerical, and theoretical data found in the open literature for inert and chemically reactive flows. The Quantum-Kinetic (QK) chemistry model with a full set of 19 chemical reactions has been implemented into the code and it proved to be essential in the correct prediction of the shock wave structure and heating flux to the vehicle's surface during the re-entry phase. Having implemented the QK chemistry model, the dsmcFoam solver was employed to investigate thermal protection system discontinuities. These TPS discontinuities, representative of panel-to-panel joints or the impact of micro meteorites/ice droplets, were modelled as a family of cavities with different length-to-depth ratios. The results showed that the cavity length has a significant impact on the flowfield structure and aerodynamic surface quantities distribution inside and around the cavities. In addition, for L/D = 5, the flow separates at the cavity upstream lip and attaches to the cavity bottom surface, representing a potentially catastrophic feature under rarefied gas conditions. Furthermore, the same phenomena is only observed in the continuum regime when L/D > 14.

Socionomer är en av de yrkesgrupper som ständigt möter människor som upplevt olika typer av förluster däribland personer som förlorat en närstående. Genom förändringen i DSM-5, där man tagit bort exklusionskriteriumet för sorg efterlyser man nu socionomers syn på fördelarna och nackdelarna. Syftet med denna studie var att undersöka hur en grupp kuratorer ser på vad sorg kan vara i relation till vad egentlig depression kan vara, utifrån debatten kring borttagandet av exklusionskriteriumet okomplicerad sorg i DSM-5. En kvalitativ studie genomfördes där fenomenologisk metod användes vid datainsamlingen. Fem stycken intervjuer utfördes med socionomer som arbetar som kuratorer på olika hälsocentraler i Norrbottens läns landsting. För att analysera insamlade data användes Giorgios fenomenologiska analysmetod. Slutsatserna i denna studie var att sorg beskrivs av kuratorerna som en naturlig känsla, reaktion och process som är individuell och inte har någon begränsning i tid men är övergående. Depression beskrivs som en orkeslöshet, trötthet, nedstämdhet och förlust av livsglädje som är mer konstant medan den pågår. Bedömningen av vad som är sorg och vad som är depression görs enligt kuratorerna utifrån vad personen berättar. De intervjuade kuratorerna tror att förändringen i DSM-5 inte kommer att leda till någon förändring vad gäller deras arbete i praktiken.

Mestrado em GestãoA perda de conhecimento na Administração Pública constitui um dos principais problemas que esta enfrenta no dia-a-dia. Ao encarar o conhecimento, na sociedade actual, como o recurso de maior valor estratégico, a sua perca será geradora de perdas colossais para as organizações. Adicionalmente é necessário situar o tema GCO nas organizações públicas, no campo de estudo da Gestão Pública e mostrar que a finalidade da GCO para estas organizações deve ser vista de forma mais ampla que em empresas do sector privado. Esta nova forma de perspectivar e encarar a realidade passa irremediavelmente pela introdução de novos procedimentos e conceitos de gestão inovadores e revolucionários. Visando contextualizar o conceito de Gestão do Conhecimento (GCO) e aferir a sua importância no âmbito da Administração Pública. Cumpre identificar os factores críticos positivos e negativos patentes nestas organizações, que poderão potenciar/dificultar a implementação de um sistema de GCO neste tipo de ambiente.
One of the most important problems that Public Administration faces everyday is knowledge lost. Defining knowledge as the most strategic value resource, its lost will produce relevant impact in the organizations. But Knowledge Management has a different concept with a diverse perspective when we talk about it in a Public Administration field consequently we have to define it and assume its consequences. This "new way" to scrutinize this situation involves the introduction of new procedures and innovative management concepts. Trying to contextualize and measure the Knowledge Management new concept in the Public Administration field it is crucial to identify the critical factors (negatives & positives) that could assure the effectiveness and success of the implementation of a knowledge management system.

Since DSM-III-R criteria for Overanxious Disorder (OAD) was subsumed under Generalized Anxiety Disorder (GAD) in DSM-IV, three studies have investigated the overlap between the diagnoses. Although two studies have identified children meeting both OAD and GAD criteria (OAD/GAD group), a third study has identified children who met criteria for OAD, but not GAD (OAD group). Based on finding these two groups of children, we examined whether children in the OAD group (n= 30) could be differentiated from children in the OAD/GAD group (n=81) based on self and parent report of anxious symptoms and level of functional impairment. Conditional probability rates were also calculated for each of the DSM anxious symptoms to determine their overall clinicalutility. Findings revealed that the OAD group of children experienced fewer anxious symptoms than children in the OAD/GAD group, though both groups showed some amount of impairment. The implications for research and practice are discussed.

As Redes de alta velocidade e o melhoramento rápido da performance dos microprocessadores fazem das redes de computadores um veículo apelativo para computação paralela. Não é preciso hardware especial para usar computadores paralelos e o sistema resultante é extensível e facilmente alterável. A programação por restrições é um paradigma de programação em que as relações entre as variáveis pode ser representada por restrições. As restrições diferem das primitivas comuns das outras linguagens de programação porque, ao contrário destas, não específica uma sequência de passos a executar mas antes a definição das propriedades para encontrar as soluções de um problema específico. As bibliotecas de programação por restrições são úteis visto elas não requerem que os programadores tenham que aprender novos skills para uma nova linguagem mas antes proporcionam ferramentas de programação declarativa para uso em sistemas convencionais. A tecnologia de Memoria Partilhada Distribuída (Distributed Shared Memory) apresenta-se como uma ferramenta para uso em aplicações distribuídas em que a informação individual partilhada pode ser acedida diretamente. Nos sistemas que suportam esta tecnologia os dados movem-se entre as memórias principais dos diversos nós de um cluster. Esta tecnologia poupa o programador às preocupações de passagem de mensagens onde ele teria que ter muito trabalho de controlo do comportamento do sistema distribuído. Propomos uma arquitetura orientada para a distribuição de Programação por Restrições que tenha os mecanismos da propagação e da procura local como base sobre um ambiente CC-NUMA distribuído usando memória partilhada distribuída. Os principais objetivos desta dissertação podem ser sumarizados em: - Desenvolver um sistema resolvedor de restrições, baseado no sistema AJ ACS [3], usando a linguagem ”C', linguagem nativa da biblioteca de desenvolvimento paralelo experimentada: O PM2 [4] - Adaptar, experimentar e avaliar a adequação deste sistema resolvedor de restrições usando DSM-PM2 [1] a um ambiente distribuído assente numa arquitetura CC-NUMA; /ABSTRACT - High-speed networks and rapidly improving microprocessor performance make networks of workstations an increasingly appealing vehicle for parallel computing. No special hardware is required to use this solution as a parallel computer, and the resulting system can be easily maintained, extended and upgraded. Constraint programming is a programming paradigm where relations between variables can be stated in the form of constraints. Constraints differ from the common primitives of other programming languages in that they do not specify a step or sequence of steps to execute but rather the properties of a solution to be found. Constraint programming libraries are useful as they do not require the developers to acquire skills for a new language, providing instead declarative programming tools for use within conventional systems. Distributed Shared Memory presents itself as a tool for parallel application in which individual shared data items can be accessed directly. In systems that support Distributed Shared Memory, data moves between main memories of different nodes. The Distributed Shared Memory spares the programmer the concerns of massage passing, where he would have to put allot of effort to control the distributed system behavior. We propose an architecture aimed for Distributed Constraint Programming Solving that relies on propagation and local search over a CC-NUMA distributed environment using Distributed Shared Memory. The main objectives of this thesis can be summarized as: - Develop a Constraint Solving System, based on the AJ ACS [3] system, in the C language, the native language of the experimented Parallel library - PM2 [4]; - Adapt, experiment and evaluate the developed constraint solving system distributed suitability by using DSM-PM2 [1] over a CC-NUMA architecture distributed environment;

This thesis aims to show that, although the Diagnostic and Statistical Manual of Mental Disorders (DSM), since its third edition, states the atheoretical character of itsmethodology, there is a relevant contribution of the psychoanalytical theory about hysteria that underlies the Somatoform Disorders and Dissociative Disorders described in it. In order to do so, we have selected events that illustrate the controversial situations that exposed psychiatry to public questioning in terms of its scientific base and, then, organized a brief history of the development of psychiatric classifications, identifying the methodology used in its elaboration. We have verified that the application of the scientific method to the study of mental diseases, having been inspired by other fields such as botanic and physics, was associated with the objective of establishing a universal classification of mental diseases. The reference to the scientific method led psychiatry to a bipolarity between a base organicism and another psychogenic aspect, not having ever, in the range of scientific methodology, been able to solve the deadlock of the establishment of the etiology of mental diseases. The dissemination of psychoanalysis in the United States, following Freud conferences in 1909 at Clark University and also through Adolf Meyer's work, influenced the first two versions of the manual, and led to a movement of the North American psychiatry by suppressing these references from DSM-III. It was considered that the psychoanalytic etiology of the mental diseases did not suit science and threatened to disassociate psychiatry from medicine. On the other hand, studies in dependability that had taken place in Europe and North America, in mid-20th century, revealed problems in the validation of diagnosis, which led the American Psychiatry Association (APA) to deal with the lack of validity of the diagnosis by increasing its dependability, by applying a statistical index (Cohen's Kappa coefficiet), and to standardize the clinic interview. We show that these efforts constitute strategies for the exclusion of the subject not only from the manual, but also the clinic and professional training. Finally, we have specified the diagnosis of the Conversion Disorder, which has been historically connected to hysteria - an extinct category from tje manual - as an example of the psychoanalytic heritage of the DSM.Esta dissertação objetiva demonstrar que, embora o Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM), desde sua terceria edição, afirme o caráter ateórico de sua metodologia, há uma relevante contribuição da teoria psicanalítica sobre a histeria subjacente aos Transtornos Somatoformes e aos Transtornos Dissociativos ali descritos. Para isso, relacionamos eventos que demonstram as controvertidas situações que expuseram a psiquiatria ao questionamento público de suas bases científicas para, em seguida, realizar um breve histórico sobre o desenvolvimento das classificações psiquiátricas, identificando a metodologia empregada em sua elaboração. Verificamos que a aplicação do método científico ao estudo das doenças mentais, tendo sido inspirado por outras disciplinas, como a botânica e a física, associou-se ao objetivo de estabelecimento de uma classificação universal das doenças mentais. A referência ao método científico levou a psiquiatria a uma bipolaridade entre um oraganicismo de base e outra vertente psicogênica não tendo jamais, no âmbito da metodologia científica, conseguido resolver o impasse do estabelecimento da etiologia das doenças mentais. A difusão da psicanálise nos Estados Unidos, a partir das conferências de Freud em 1909, na Universidade Clark e por intermédio do trabalho de Adolf Meyer, influenciou as duas primeiras versões do manual e levou a um movimento da psiquiatria norte-americana pela supressão dessas referências a partir do DSM-III. Considerava-se que a etiologia psicanalítica das doenças mentais não se adequava à ciência, e ameaçava desvincular a psiquiatria da medicina. Por outro lado, estudos de confiabilidade realizados na Euroa e na América, em meados do século vinte, revelaram problemas na validação dos diagnósticos. Isto levou a Associação Psiquiátrica Americana (APA) a tratar a falta de validade dos diagnósticos pelo aumento de sua confiabilidade, pela aplicação de um índice estatítico (o Cieficiente Kappa de Cohen), e a normalizar a entrevista clínica. Demonstramos como esses esforços constituem estratégias para a exclusão do sujeito não apenas do manual, como também da clínica e da formação profissional. Por fim, especificamos o diagnóstico de Transtorno Conversivo, historicamente vinculado à histeria - categoria extinta do manual - como exemplo da herança psicanálitica no DSM.

This thesis analyses the violence perpetrated against transgender people. It scrutinizes the concept of transgender and the important role of transitioning. It looks at the essentialist and social constructionist debate and its relation to transgender. In this thesis, I will advocate a theory of violence in which violence is understood as structural. I will advocate bringing the lived experience of transgender people to the foreground in theorizing about embodiment. Hereby, I will especially focus on discursive violence and the violation of human rights. I will relate transgender and the importance of transitioning to DSM’s understanding of Gender Identity Disorder. Consequently, I will uncover DSM’s subtle misogyny and transphobia and argue that it perpetrates discursive violence against transgender people. In addition, I will scrutinize the direct and indirect ways it violates the human rights of transgender people. Finally, the thesis will discuss the suggestions the Hammarberg report has made in order to improve the human rights situation of transgender persons.

The modeling of Micro- and NanoElectroMechanical Systems (MEMS and NEMS) requires new computational techniques that can deal efficiently with geometric complexity and scale dependent effects that may arise. Reduced feature sizes increase the coupling of physical phenomena and noncontinuum behavior, often requiring models based on molecular descriptions and/or first principles. Furthermore, noncontinuum effects are often localized to small regions of (relatively) large systemsprecluding the global application of microscale models due to computational expense. Multiscale modeling couples efficient continuum solvers with detailed microscale models to providing accurate and efficient models of complete systems.
This thesis presents the development of multiscale modeling techniques for nonequilibrium microscale gas phase phenomena, especially thermally driven microflows. Much of this focuses on improving the ability of the Information Preserving DSMC (IP-DSMC) to model thermally driven flows. The IP-DSMC is a recent technique that seeks to accelerate the solution of direct simulation Monte Carlo (DSMC) simulations by preserving and transporting certain macroscopic quantities within each simulation molecules. The primary contribution of this work is the development of the Octant Splitting IP-DSMC (OSIP-DSMC) which recovers previously unavailable information from the preserved quantities and the microscopic velocities. The OSIP-DSMC can efficiently simulate flow fields induced by nonequilibrium systems, including phenomena such as thermal transpiration. The OSIP-DSMC provides an efficient method to explore rarefied gas transport phenomena which may lead to a greater understanding of these phenomena and new concepts for how these may be utilized in practical engineering systems.
Multiscale modeling is demonstrated utilizing the OSIP-DSMC and a 2D BEM solver for the continuum (heat transfer) model coupled with a modified Alternating Schwarz coupling scheme. An interesting application for this modeling technique is Thermal Sensing Atomic Force Microscopy (TSAFM). TSAFM relies on gas phase heat transfer between heated cantilever probes and the scanned surface to determine the scan height, and thus the surface topography. Accurate models of the heat transfer phenomena are required to correctly interpret scan data. This thesis presents results demonstrating the effect of subcontinuum heat transfer on TSAFM operation and explores the mechanical effects of the Knudsen Force on the heated cantilevers.

This research provides an examination of DSM personality disorder criteria using the DSM-IV-TR Axis II and Dimensional Assessment of Personality Pathology (DAPP) frameworks. Data. The British Psychiatric Morbidity of Adults Living in Private Households, 2000 (BPMS) survey, an epidemiological study covering England, Scotland and Wales (n=8580) was obtained from the UK Data Archives at the University of Essex. The personality disorder section of the interview was measured by self-report methods using the SCID-II (Structured Clinical Interview for DSM Axis II Disorders) screening questionnaire. Methods. The statistical software programme MplusTM version 5.21 was used to carry out statistical analyses. Item response theory (IRT) methods produced discriminatory and severity characteristics of the DSM personality disorder criteria. Confirmatory factor analysis (CFA) was utilized to examine the latent factors of the DSM personality disorders and clusters, and DAPP primary traits and domains. Hybrid modelling that combines CFA with latent class analysis techniques (LCFA) identified sub-populations within both the DSM and DAPP structures. Binomial logistic regression analyses of these sub-populations provided examination of group characteristics. Results. IRT item characteristic parameters indicated a number of DSM personality disorder are not performing well in terms of the underlying 11 disorders and domains. CFA indicated good model fit for the structures on inclusion of a number of extra specified relationships between some criteria. LCFA identified sub-populations that differ in terms of severity and likelihoods of criteria endorsements. Conclusions. IRT and LCFA both confirm that a number of criteria used for the assessment of personality disorder have poor discriminant validity, and these should be reviewed as indicators in new guidelines. Analyses at sub-population levels provide support for dimensional trait-type representations of personality disorder, and have provided useful profiles for hidden groups that have not been previously identified and should be of interest for clinicians, policy-makers and working groups for future editions of psychiatric guidelines.

Background: Despite an abundance of questionnaire data, the prevalence of clinically significant and medically unexplained pain syndromes in the general population has rarely been examined with a rigid personal-interview methodology. Objective To examine the prevalence of pain syndromes and DSM-IV pain disorder in the general population and the association with other mental disorders, as well as effects on disability and health-care utilization.
Methods: Analyses were based on a community sample of 4.181 participants 18–65 years old; diagnostic variables were assessed with a standardized diagnostic interview (M-CIDI).
Results: The 12-month prevalence for DSM-IV pain disorder in the general population was 8.1%; more than 53% showed concurrent anxiety and mood disorders. Subjects with pain disorder revealed significantly poorer quality of life, greater disability, and higher health-care utilization rates compared to cases with pain below the diagnostic threshold. The majority had more than one type of pain, with excessive headache being the most frequent type.
Conclusions: Even when stringent diagnostic criteria are used, pain disorder ranks among the most prevalent conditions in the community. The joint effects of high prevalence in all age groups, substantial disability, and increased health services utilization result in a substantial total burden, exceeding that of depression and anxiety.

International Telemetering Conference Proceedings / October 26-29, 1987 / Town and Country Hotel, San Diego, CaliforniaThis abstract describes the hardware and software necessary for reserialization of asynchronous imbedded image data. The purpose of the DSI Model 7303 System is to reformat space shuttle imbedded (Payload Data Interleaver) PDI data. the system consists of two decoms, a DSI model 7303A and a DSI Model 7303B. The input to the 7303A box is 0I or NSP data (NRZ-L & CLOCK). The 7303A Frame syncs to the 0I or NSP data. The 7303A is front panel programmed to strip out only the imbedded PDI data and pass this data to the 7303B Decom. The 7303B Frame syncs to the PDI frame sync pattern. A second strip zone defines which words in the PDI frame get passed to the FIFO. A 24K byte ring FIFO Buffer is used to buffer data before reserialization for output. The serial output rate is a function of how many programmed PDI words per second are stripped out and the FIFO management status. The output bit rate is from a microprocessor controlled NCO. This system Makes possible real time video of Shuttle PDI data.

Previous issue date: 2010-12-15The demand for spatial data processing systems that support the creation of massive applications has steadily grown in the increasingly ubiquitous computing world. These demands aims to explore the large amount of existing data to assist people s daily lives and provide new tools for business and government. Most of the current solutions to process spatial data do not meet the scalability needed, and thus new solutions that efficiently use distributed computing resources are needed. This work presents a distributed and scalable system called DSI-RTree, which implements a distributed index to process spatial data in a cluster of computers. We also have done a review of details related to the construction of the distributed spatial index, by addressing issues such as the size of data partitions, how that partitions are distributed and the impact of these definitions in the message flow on the cluster. An equation to calculate the size of the partitions based on the size of data sets is proposed, to ensure efficiently query processing on the proposed architecture. We have done some experiments running window queries in spatial data sets of 33,000 and 158,000 polygons and the results showed a scalability greater than linear.
Em face de um mundo computacional ubíquo cada vez mais possível, tem crescido constantemente a necessidade de sistemas de processamento de dados espaciais que suportem a criação de aplicações massivas para explorar a grande quantidade de dados existente, a fim de auxiliar a vida cotidiana das pessoas e prover novas ferramentas para empresas e governo. Soluções atuais de processamento, em sua maioria, não possuem a escalabilidade necessária para atender esta demanda e novas soluções distribuídas que usam eficientemente os recursos computacionais são necessárias. Este trabalho apresenta o DSIRTree, um sistema distribuído e escalável, que implementa a indexação e processamento distribuído de dados espaciais em um cluster de computadores. Uma avaliação de parâmetros da construção do índice espacial distribuído é realizada, abordando aspectos como o tamanho das partições criadas, a forma de distribuição destas partições e o impacto destas definições na troca de mensagens entre as máquinas do cluster. Uma fórmula para cálculo do tamanho das partições conforme o tamanho dos datasets é proposta, a fim de garantir eficiência no processamento de consultas na arquitetura projetada. Testes práticos do sistema mostraram uma escalabilidade maior que linear no processamento de consultas de janela em datasets espaciais de 32 e 158 mil polígonos.

Der volle Inhalt der QuelleAnnotation:
This thesis investigates the modelling of drying processes for the promotion of market-led Demand Side Management (DSM) as applied to the UK Public Electricity Suppliers. A review of DSM in the electricity supply industry is provided, together with a discussion of the relevant drivers supporting market-led DSM and energy services (ES). The potential opportunities for ES in a fully deregulated energy market are outlined. It is suggested that targeted industrial sector energy efficiency schemes offer significant opportunity for long term customer and supplier benefit. On a process level, industrial drying is highlighted as offering significant scope for the application of energy services. Drying is an energy-intensive process used widely throughout industry. The results of an energy survey suggest that 17.7 per cent of total UK industrial energy use derives from drying processes. Comparison with published work indicates that energy use for drying shows an increasing trend against a background of reducing overall industrial energy use. Airless drying is highlighted as offering potential energy saving and production benefits to industry. To this end, a comprehensive review of the novel airless drying technology and its background theory is made. Advantages and disadvantages of airless operation are defined and the limited market penetration of airless drying is identified, as are the key opportunities for energy saving. Limited literature has been found which details the modelling of energy use for airless drying. A review of drying theory and previous modelling work is made in an attempt to model energy consumption for drying processes. The history of drying models is presented as well as a discussion of the different approaches taken and their relative merits. The viability of deriving energy use from empirical drying data is examined. Adaptive neuro fuzzy inference systems (ANFIS) are successfully applied to the modelling of drying rates for 3 drying technologies, namely convective air, heat pump and airless drying. The ANFIS systems are then integrated into a novel energy services model for the prediction of relative drying times, energy cost and atmospheric carbon dioxide emission levels. The author believes that this work constitutes the first to use fuzzy systems for the modelling of drying performance as an energy services approach to DSM. To gain an insight into the 'real world' use of energy for drying, this thesis presents a unique first-order energy audit of every ceramic sanitaryware manufacturing site in the UK. Previously unknown patterns of energy use are highlighted. Supplementary comments on the timing and use of drying systems are also made. The limitations of such large scope energy surveys are discussed.

"This dissertation is devoted to the computational investigation of supersonic gas flows in rectangular nanochannels with scales between 100 nm and 1000 nm, using an unstructured three-dimensional Direct Simulation Monte Carlo (U3DSMC) methodology. This dissertation also contributes to the computational mathematics background of the U3DSMC method with validations and verifications at the micronscale and nanoscale, as well as with the investigation of the statistical fluctuations and errors associated with U3DSMC simulations at the nanoscale. The U3DSMC code is validated by comparisons with previous two dimensional DSMC simulations of flows in micron-scale rectangular channels. The simulation involves the supersonic flow of nitrogen into a microchannel with height of 1.2 m and width of 6 m. The free stream conditions correspond to a pressure of 72,450 Pa, Mach number , Knudsen number and mean free path nm. The U3DSMC centerline temperature, heat flux to the wall, and mean velocity as a function of the transverse direction are in very good agreement with previous 2D results. Statistical fluctuations and errors in U3DSMC have added significance in nanoscale domains because the number of real particles can be very small inside a computational cell. The effect of the number of samples, the number of computational particles in a Delaunay cell, and the Mach number on the fractional errors of density, velocity and temperature are investigated for uniform and pressure-driven nanoscale flows. The uniform nanoflow is implemented by applying a and free stream boundary condition with m-3, K, nm in a domain that requires resolution of a characteristic length scale nm. The pressure-driven flows consider a nanochannel of 500 nm height, 100 nm width and 4 m length. Subsonic boundary conditions are applied with inlet pressure 101,325 Pa and outlet pressure of 10132.5 Pa. The analysis shows that U3DSMC simulations at nanoscales featuring 10-30 particles per Delaunay cell result in statistical errors that are consistent with theoretical estimates. The rarefied flow of nitrogen with speed ratio of 2, 5, and 10, pressure of 10.132 kPa into rectangular nanochannels with height of 100, 500 and 1000 nm is investigated using U3DSMC. The investigation considers rarefaction effects with =0.481, 0.962, 4.81, geometric effects with nanochannel aspect ratios of (L/H) from AR=1, 10, 100 and back-pressure effects with imposed pressures from 0 to 200 kPa. The computational domain features a buffer region upstream of the inlet and the nanochannel walls are assumed to be diffusively reflecting at the free stream temperature of 273 K. The analysis is based on the phase space distributions as well as macroscopic flow variables sampled in cells along the centerline. The phase space distributions show the formation of a disturbance region ahead of the inlet due to slow particles backstreaming through the inlet and the formation of a density enhancement with its maximum inside the nanochannel. The velocity phase-space distributions show a low-speed particle population generated inside the nanochannel due to wall collisions which is superimposed with the free stream high-speed population. The mean velocity decreases, while the number density increases in the buffer region. The translational temperature increases in the buffer region and reaches its maximum near the inlet. For AR=10 and 100 nanochannels the gas reaches near equilibrium with the wall temperature. The heat transfer rate is largest near the inlet region where non-equilibrium effects are dominant. For =0.481, 0.962, 4.81, vacuum back pressure, and AR=1, the nanoflow is supersonic throughout the nanochannel, while for AR=10 and 100, the nanoflow is subsonic at the inlet and becomes sonic at the outlet. For =0.962, AR=1, and imposed back pressure of 120 kPa and 200 kPa, the nanoflow becomes subsonic at the outlet. For =0.962 and AR=10, the outlet pressure nearly matches the imposed back pressure with the nanoflow becoming sonic at 40 kPa and subsonic at 100 kPa. Heat transfer rates at the inlet and mass flow rates at the outlet are in good agreement with those obtained from theoretical free-molecular models. The flows in these nanochannels share qualitative characteristics found in microchannels ad well as continuum compressible flows in channels with friction and heat loss. The rarefied flow of nitrogen with speed ratio of 2, 5, 10, at an atmospheric pressure of 101.32 kPa into rectangular nanochannels with height of 100 and 500 nm is investigated using U3DSMC. The investigation considers rarefaction effects with =0.0962 and 4.81, geometric effects with nanochannel aspect ratios of (L/H) of AR=1 and 10 and vacuum back-pressure. Phase plots and sample-averaged macroscopic parameters are used in the analysis. Under vacuum back pressure the centerline velocity decreases in the buffer region from its free stream value. For 0.481, 0.0962 and AR=1 the Mach number is supersonic at the inlet and remains supersonic throughout the nanochannel. For 0.481, 0.0962 and AR=10, the flow becomes subsonic at the inlet and shows a sharp increase in pressure. The Mach number, subsequently, increases and reaches the sonic point at the outlet. For 0.481, 0.0962 and AR=1 the translational temperature reaches a maximum near the inlet and decreases monotonically up to the outlet. For 0.481, 0.0962 and AR=10, the translational temperature reaches a maximum near the inlet and then decreases to come in near equilibration with the wall temperature of 273 K. "

The World Health Organization has estimated that by 2030, approximately 350 million people will be diagnosed with Type 2 diabetes mellitus (T2DM). Currently, 18.8 million people are diagnosed with T2DM. An additional 7 million people have high blood sugar but have yet to have an official diagnosis of diabetes. The literature supports early identification and prevention are key to reducing the severity of T2DM its complications. The Health Belief Model, the Chronic Care Model and Orem's Theory of Self-Care guided the current proposal, whose purpose was to develop and validate a new T2DM DSME module. A validation of the DSME module was completed by 5 local diabetic clinical experts. Each expert reviewed the DSME modules then completed a 10-question Likert-type scale survey. The survey was used to measure the content amount, ease of use, and visual presentation. Descriptive analysis was employed to analyze these data.
Results revealed that all strongly agreed that the education module was easy to read and follow. They also strongly agreed that there was an adequate amount of educational information within the module. Additional comments from the experts resulted in minor revision to the new DSME. A future pilot study comparing current education to the newly validated DSME module will be implemented post-graduation. Changing the diabetic teaching culture into an improved patient focus role has the potential to reduce the economic healthcare impact and empower patients to bring about positive social change. Social change will also improve trust and confidence among patients within the healthcare organization.

Includes bibliographical references (p. 133-139).
The goal of the present thesis is to develop a practical method for simulating low-signal kinetic (small-scale) gaseous flows. These flows have recently received renewed attention in connection with the design and optimization of MEMS/NEMS devices operating in gaseous environments; they are typically described using the Boltzmann equation which is most efficiently solved using a stochastic particle simulation method known as direct simulation Monte Carlo (DSMC). The latter is a simple and versatile simulation method which is very efficient in producing samples of the single particle distribution function which can be used for estimating hydrodynamic properties. Unfortunately, in cases where the signal of interest is small (e.g. low-speed flows), the computational cost associated with reducing the statistical uncertainty of simulation outputs becomes overwhelming. This thesis presents a variance reduction approach for reducing the statistical uncertainty associated with low-signal flows thus making their simulation not only possible but also efficient. Variance reduction is achieved using a control variate approach based on the observation that low-signal flows are typically close to an equilibrium state. As with previous variance reduction methods, significant variance reduction is achieved making the simulation of arbitrarily small deviations from equilibrium possible. However, in contrast to previous variance-reduction methods, the method proposed, which we will refer to as VRDSMC, is able to reduce the variance with virtually no modification to the standard DSMC algorithm. This is achieved by introducing an auxiliary equilibrium simulation which, via an importance weight formulation, uses the same particle data as the non-equilibrium (DSMC) calculation; subtracting the equilibrium from the non-equilibrium hydrodynamic fields drastically reduces the statistical uncertainty of the latter because the two fields are correlated. By retaining the basic DSMC formulation, in contrast to previous approaches, the VRDSMC approach combines ease of implementation with computational efficiency and the ability to simulate all molecular interaction models available within the DSMC formulation. Our validation tests show that the proposed VRDSMC method provides considerable variance reduction for only a small increase in computational cost and approximation error compared to equivalent DSMC simulations. In other words, by addressing the major weakness associated with DSMC, VRDSMC is well suited to the solution of low-signal kinetic problems of practical interest.

This study explored: (1) The test-retest reliability of DSM III lifetime diagnoses in 69 active alcoholic subjects interviewed twice, before entering treatment and 4 weeks later with the computerized format of the DISSI (derived from the NIMH-Diagnostic Interview Schedule). (2) The stability of psychiatric diagnoses yielded by both interviews as influenced by subjects' age, gender, current level of psychological distress and current toxic status. Poor agreement (Kappa values below 0.5) was found for panic disorder (k = 0.337) and phobic disorder (k = 0.477) while generalized anxiety disorder and depression/dysthymia presented only fair agreement (k = 0.658 and k = 0.696 respectively). Current levels of psychological distress assessed by the Hopkins Symptom Checklist-58 (HSCL-58) was found to predict the risk of inconsistent reports. Contrary to expectations abstinence did not significantly influence the report of symptoms; neither did the age or gender of the respondents. Levels of self-perceived psychological distress may influence the recall of past symptom experiences among alcoholics and thus affect the reliability of lifetime reports in this population.

This study will focus on the feasibility of demand side electricity management on
underground refrigeration systems. It will include a relevant literature study, the
investigation process, a simulation model, expected simulated results,
implementation of DSM on an underground refrigeration system, actual results,
recommendations of further study, and a conclusion.
Eskom is presently struggling to adhere to the electricity demand in South Africa,
specifically in the peak consuming periods. It was proposed that Demand Side
Management possibilities must be investigated and evaluated on South-African
gold mines.
The gold mining industry consumes approximately 26% of the electricity supplied
by Eskom. Mines possess extensive machinery which consume much power in
their mining activities. One of the most energy intensive machines is the
refrigeration system machines.
Demand Side Management was previously successfully implemented on surface
refrigeration systems and on cascade refrigeration systems. Mining depths
increase continuously and surface refrigeration systems become inadequate. An
underground refrigeration system is a viable option to aid this problem. The possibility of Demand Side Management in underground refrigeration systems
will be investigated. A simulation model will be created of the system and various
control strategies will be applied and evaluated. These strategies will endeavour
to reduce loads during the Eskom peak consumption periods.
The control strategy was implemented on the refrigeration system and load
reduction results were obtained. The average load reduction for the evening peak,
excluding condonable days, for the month of August 2009 was 6.60 MW. The
average morning load reduction, excluding condonable days, was 6.06 MW. Load
profiles from 1 October 2009 until 15 October 2009 show that the reduction for the
evening peak, excluding condonable days, was 5.24 MW.Thesis (M.Ing. (Electrical Engineering))--North-West University, Potchefstroom Campus, 2010

The continual increase in electrical energy demand in South Africa has resulted in a precariously low reserve margin in supply from the primary utility, Eskom. This resulted in extensive load shedding throughout the country. Far-reaching measures had to be introduced in order to ensure a reliable supply of electricity.
DSM interventions were shown to be very successful short term solutions for the mining industry, reducing the strain on the national grid. This resulted in an increasing number of investigations to broaden the base of DSM projects to other industries.
One such intervention was the Usutu-Vaal water distribution scheme, situated near Standerton, South Africa. This scheme includes the Grootdraai, Tutuka, Grootfontein, Rietfontein and Naauwpoort pumping stations. With a combined installed capacity of 36.5MW and the extremely large water storage capacities, these pump stations have been identified as prime candidates for DSM interventions.
This dissertation discusses the method followed for a DSM project intervention and the results of the implementation. The national grid was relieved by an average of 12.3 MW during the Eskom weekday peak period, by shifting the pumping load into the off-peak periods. Simulations have shown that an annual financial saving of approximately R4.7million may be expected.Thesis (MIng (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2013

The purpose of this study is to operationalize the DSM-III-R criteria for bulimia. This study shows how the lack of DSM-III-R quantification results in high within-group sample variability for bulimic symptomatology and greatly reduces the validity of research outcomes. The study problem for this research is: How can the DSM-III-R criteria for bulimia be measured and quantified in order to procure a more valid sample of bulimics for research and treatment? The first DSM-III-R criterion for bulimia is: "Recurrent episodes of binge eating." This criterion was operationalized using the Binge Eating Quiz and by calculating the mean daily binge caloric consumption of 108 female subjects who met the DSM-III-R criteria for bulimia. The second DSM-III-R criterion for bulimia is: "A strong feeling of lack of control over eating behavior during the eating binges." This criterion was operationalized by administering the Eating Attitude Test to 108 individuals who met the DSM-III-R criteria for bulimia. The third DSM-III-R criterion for bulimia is: "The person regularly engages in either self-induced vomiting, use of laxatives or diuretics, strict dieting or fasting, or vigorous exercise in order to prevent weight gain." Of these several purging variables, the one most commonly used by bulimics in this study (N = 108), and in all previous research studies was self-induced vomiting. Self-induced vomiting was measured by giving 108 female subjects devices to be attached to their toilets in order to measure vomit in cubic centimeters. The fourth DSM-III-R criterion for bulimia is: "Persistent overconcern with body shape and weight." This criterion was operationalized by a test designed and tested by this researcher, the Body Image Scale (BIS). The BIS was administered to 108 female subjects who met the DSM-III-R criteria for bulimia. The fifth DSM-III-R criterion for the diagnosis of bulimia is: "A minimum average of two binge eating episodes a week for at least three months." This criterion is especially vague because a binge to one person may merely infer one candy bar; while to another individual, a binge may suggest a dozen donuts. Although vomiting frequency is also a vague unit of measurement for bulimia, it is perhaps less so than bingeing. Consequently, "a minimum average of two vomiting episodes a week for at least three months" may be a better measurable characteristic for this DSM-III-R criterion. When the DSM-III-R criteria for bulimia was operationalized on 108 female subjects who answered "yes" to the five DSM-III-R criteria, only 46.30% (N = 50) scored significantly on the BEQ, Binge Caloric Value Count, EAT, Vomit Count, and the BIS. Consequently, only 50 out of 108 potential subjects would render valid research subject inclusion in bulimic research. Thus, this study shows that the DSM-III-R criteria for bulimia should only be used as an initial screening device for subject inclusion and treatment in research studies. Other tools, such as those used in this study, should then be employed in order to obtain a more valid study sample in order to procure more empirical research outcomes. (Abstract shortened by UMI).

Clinical utility has been offered by numerous researchers as a criterion for understanding the value of diagnostic constructs, but it does not yet have a standard operational definition or recommended forms of measurement. The construct has significant overlap with diagnostic validity and it is possible that sub-domains of clinical utility may emerge that would contribute to development of a scale which could assess for improvements and degradations following nosological revisions, and also provide opportunity for cross-analysis with alternative systems of mental health diagnosis. Therefore, the present study collected survey data from psychologists about the clinical utility of the DSM-5, using online data collection and quantitative methods. Seven questions of clinical utility were rated using a 5 point likert scale for each of the DSM-5's diagnostic categories and for the DSM-5 as an overall nosology. Descriptive data, internal consistency and inter-item correlations were analyzed so that results could help address research questions posed about the clinical utility of the DSM-5's diagnostic categories, the merits of DSM-5 when compared to DSM-IV, and additional recommendations regarding optimal measurement of the clinical utility of diagnostic constructs.

Automatic 3D building reconstruction has been a hot research area; a task which has been done manually even up today. Automating the task of building reconstruction enables more applications where up to date information is of great importance. This thesis proposes a system to extract parametric buildings and trees from dense aerial stereo image data. The method developed for the tree identification and parameterization is a totally new approach which have yielded great results. The focus has been to extract the data in such a way that small flying platforms can use it for navigational purposes. The degree of simplification is therefor high. The building parameterization part starts with identifying roof faces by Region Growing random seeds in the digital surface model (DSM) until a coverage threshold is met.For each roof face a plane is fitted using a Least Square approach.The actual parameterization is started with calculating the intersection between the roof faces. Given the nature of 2.5D DSM data there is no possibility to perform wall fitting. Therefor all the walls will be constructed with a 2D line Hough transform of the border data of all the roof faces. The tree parameterization is done by searching for possible roof face topologies resembling the signature of a tree. For each possible tree topology a second degree polynomial surface is fitted to the DSM data covered by the faces in the topology. By looking at the parameters of the fitted polynomial it is then possible to determine if it is a tree or not. All the extraction steps were implemented and evaluated in Matlab, all algorithms have been described, discussed and motivated in the thesis.

Esta dissertação apresenta os algoritmos considerados estado-da-arte para gerenciamento dinâmico de espectro (DSM). As técnicas de otimização utilizadas nos algoritmos DSM são abordadas e brevemente discutidas para melhor entendimento, descrição e comparação dos algoritmos. A análise comparativa entre os algoritmos foi realizada considerando o ganho em taxa (kbps) obtido em simulações. Para tanto, foi realizado em laboratório um conjunto de medições de função de transferência direta e de acoplamento, posteriormente utilizadas nas simulações dos algoritmos IWF, ISB e SCALE. Os resultados obtidos nas simulações através do uso das funções de transferência medidas mostraram melhor desempenho quando comparados aos demais resultados ao considerar funções de transferência obtidas a partir do padrão 1% pior caso, resultado este reflexo da aproximação 1% em que os pares apresentam maiores níveis de crosstalk em todas as frequências da função de transferência. Dentre os algoritmos comparados, o ISB e SCALE obtiveram desempenho semelhante em canais padronizados, ficando o IWF com o desempenho próximo ao SSM. No entanto, nas simulações em cenários com canais medidos, os três algoritmos tiveram ganhos muito próximo devido ao baixo nível de crosstalk.
This M.Sc. thesis presents state-of-art algorithms for dynamic spectrum management (DSM). The strategy and description of each DSM algorithm are presented and briefly discussed as well as a comparative analysis between them for better understanding. This analysis was conducted considering the rate gain (kbps) obtained from computer simulations and the results are presented by tables and rate region curves. Additionally, it was conducted in laboratory a set of direct and coupling transfer function measurements. Later on, those measurements were used during DSM algorithms simulations; this dissertation focused in the IWF, ISB and SCALE algorithms. The results obtained from the transfer function measurements showed better performance compared to the results with transfer function 1% worst-case model. The later considers 1% of pairs present the biggest crosstalk level in all transfer function frequencies. In the case where standardized channels were employed, ISB and SCALE obtained similar performances whereas IWF had a performance quite similar to SSM. On the other hand, these three algorithms had similar gain in simulations evolving the measured channels because the low crosstalk level.

In this study, it uses Direct Simulation Monte Carlo (DSMC) method with trapezoidal meshes to simulate characteristics of flows field for two-dimensional convergent micronozzle. The influence of the micro/nanoscale rarefied gas effects on flow characteristics were investigated and analyzed. First, real three-dimensional micronozzle flow field use simplified to a two–dimensional convergent micronozzle. Modified no time counter (M-NTC) rule is applied on the selection of representative collision pairs. Different reflect boundary conditions, such as specular/diffuse/isotropic reflection an adopted as wall boundary conditions. Finally the effects of back pressure, reflection conditions, and rarefaction on the flow field characteristics in two-dimensional convergent micronozzle are studied.

The direct simulation Monte Carlo method was applied to simulate the flows in uniform, parallel, series, and T-shape microchannels. For the uniform microchannel case, both the supersonic and subsonic flows have been considered. The effect of the Knudsen number (Kn) on the flow properties and the heat transfer characteristics were investigated. Some significant flow features, such as the flow acceleration along the channel, the nonlinear pressure distribution, and the velocity slip near the wall, due to the compressibility and the rarefaction of the microflow were specified. Most of the wall heat flux occurs within the channel entrance region when the wall temperature is higher than the bulk flow temperature. Furthermore, in supersonic flow case, the wall heat flux is mainly caused by the deceleration of the flow due to the wall friction.

The microchannel is a very important element in Microelectro- mechanical system, and the gas flow in the channel will affect the performance of microsystem directly. Hence, the regime of interaction between microchannel and working gas becomes a serious topic. Because of the approach of characteristic length of microchannel to the mean free path of working gas, the thesis takes advantage of the concept of probability and statistics to simulate the behavior of molecules in the system with the theory of molecular gas dynamics, and then show the profiles of flow fields finally. This method is well-known as Direct Simulation of Monte Carlo Method. The thesis have simulated five different cases of supersonic square microchannel flows with different channel sizes and got the regimes handling the flow field of microchannels. The regimes include the effect of inertia, viscous effect and effect of relaxation. The effects are caused respectively from the gas injected from the inlet, walls of the channel, and the outlet and channel length. The obvious shack waves in the local region of the center of inlet, the non-zero flow velocity and the temperature jump in the region close to walls of channel are also found. After the comparison of three dimensional simulated results and the two dimensional results done by other researchers, the deviation will be great if two dimensional simulated result is used to explain square microchannel flow field. Many physical phenomena, such as shock waves in the region of the inlet, will be far away from the channel inlet in the direction to channel outlet. This resulted from the ignorance of one side of channel walls. Hence, the simulate model must be built very carefully when DSMC is used to analyse the flow field of microsystem.

In this paper, the direct simulation Monte Carlo has been applied to compute 3-D Low-speed Micro-channel Flows, then compare with the difference in 2-D and 3-D flows. Variation of the Knudsen number is obtained by change the inlet pressure while keeping the pressure ratio. The effects of varying Knudsen number on flow property were investigated. The VHS model and Nitrogen has been applied. The result shows that simulation of 3-D differs a lot from 2-D. In the velocity distribution, the result of the 3-D is lower than 2-D,about only 65% of 2-D,because the friction of the wall. In addition, compare to the different inlet pressure case, wall slip velocity increase and inner velocity decrease along the enhanced rarefaction. On the analysis of heat flux, the result of 3-D is larger then 2-D, but not distinct with high Knudsen number.

In this paper, the DSMC method was employed to investigate the flow properties in microchannels with different wall temperature and the heat transfer phenomenon between the fluid and the channel walls. The molecular collisions are simulated using the variable hard sphere (VHS) molecular model. The results of supersonic flows in microchannels show that the temperature increases near the entrance and decreases as the flow develops downstream. The subsonic flows in microchannels are simulated by different wall temperature. The higher wall temperature increases the rarefaction of the flow field. The subsonic flows in microchannels are also simulated by varying inlet pressure for a range of slip to transition regime flows. It is found that the slip velocity increases with the increase of Kn.

Modern superscalar processors exploit instruction-level parallelism (ILP) by
issuing multiple instructions in a single cycle because of increasing demand for higher
performance in computing. However, stalls due to cache misses severely degrade the
performance by disturbing the exploitation of ILP. Multiprocessors also greatly
exacerbate the memory latency problem. In SMPs, contention due to the shared bus
located between the processors's L2 cache and the shared memory adds additional delay
to the memory latency. In distributed shared memory (DSM) systems, the memory
latency problem becomes even more severe because a miss on the local memory requires
access to remote memory. This limits the performance because the processor can not
spend its time on useful work until the reply from the remote memory is received.
There are a number of techniques that effectively reduce the memory latency.
Multithreadings has emerged as one of the most promising and exciting techniques to
tolerate memory latency. This thesis aims to realize a simulator that supports software-controlled
multithreadings environment on a Distributed Shared Memory and to show
preliminary simulation results.Graduation date: 2000
