The performance of the computer programs Compleat ELEFAN, MIX, ELEFAN I, SLCA and PROJMAT was investigated using real data of six species: the bivalves Cerastoderma edule, Abra alba and Tellina tenuis; the gastropods Acteon tornatilis and Rissoa parva and the crustacean Carcinus maenas. The preciseness of estimates produced by these programs has been verified by comparing with results obtained from age-based analyses (using annuli) in C.edule and A.alba. The age-based analyses support the accuracy of both Compleat ELEFAN and MIX whose estimates were shown to be nearly identical to each other. Estimates by ELEFAN I (LFDA), which utilises a non-seasonalised version of the von Bertalanffy growth model, were generally less close to the age-based estimate and to these two programs. Relatively poorer estimates were also obtained when SLCA or PROJMAT was employed. In C.edule, using modal class progression analysis Compleat ELEFAN overestimate L∞ by 3.9% and underestimate K by 4.5%. MIX overestimate both L∞ and K by only 0.9% and 1.5%, respectively. ELEFAN I (LFDA) overestimate L∞ by 7.1%, and K by 6.1% SLCA overestimate L∞ by 10.4% and underestimate K by 24.2% while PROJMAT overestimate L∞ by 10.4% but underestimate K by 39.4%. The general pattern of results obtained in C.edule was repeated in A.alba and the other species, although in the latter no verification can be carried out.

Additive Manufacturing (AM), with its bottom-up approach enables the fabrication of highly complex geometries, the combination of multiple materials to achieve specific physical properties, and the consolidation of assemblies into single parts. Although many of the prominent processes were invented 20-30 years ago, we are now seeing rapid performance improvement and the synthesis of innovative processes that greatly expand the applications of AM. That being said, there are significant barriers to entry, one being the low throughput of additive processes when compared with more conventional methods, another being the high cost of introducing AM processes into current supply chains. Identifying key use cases where AM can be of maximum benefit is pivotal to exploit its potential. This research aims to provide methodology and tools to enable rapid estimation for part suitability in AM with physics-based and predictive models. A method is presented to estimate build time for parts manufactured via the Selective Laser Sintering process, utilizing specific metrics for part geometry and machine specific parameters. Key elements of the AM cost function are identified using the estimation model, paying close attention to assessing the impact of machine cost on the final part. In summary, these tools can be expanded to allow for not only part selection in AM, but also to act as decision tools when designing equipment..

This thesis presents a quantitative, parametric model for describing musical tension. While the phenomenon of tension is evident to listeners, it is difficult to formalize due to its subjective and multi-dimensional nature. The model is therefore derived from empirical data. Two experiments with contrasting approaches are described. The first experiment is an online test with short musical excerpts and multiple choice answers. The format of the test makes it possible to gather large amounts of data. The second study requires fewer subjects and collects real-time responses to musical stimuli. Both studies present test subjects with examples that take into account a number of musical parameters including harmony, pitch height, melodic expectation, dynamics, onset frequency, tempo, and rhythmic regularity. The goal of the first experiment is to confirm that the individual musical parameters contribute directly to the listener's overall perception of tension. The goal of the second experiment is to explore linear and nonlinear models for predicting tension given descriptions of the musical parameters for each excerpt. The resulting model is considered for potential incorporation into computer-based applications. Specifically, it could be used as part of a computer-assisted composition environment. One such application, Hyperscore, is described and presented as a possible platform for integration.

Resumo: Este trabalho apresenta um estudo paramétrico comparativo de ligações do tipo K e KK utilizando perfis tubulares circulares com afastamento entre diagonais e carregadas simetricamente. Para se comparar as ligações, foi desenvolvido um modelo numérico através do programa comercial de elementos finitos Ansys. Também foram desenvolvidos dois programas auxiliares para facilitar o estudo paramétrico. Foram analisadas 55 ligações do tipo KK e suas correspondentes K, comparando-se suas resistências. O objetivo deste trabalho é propor um critério objetivo para definir os modos de falha (1 e 2) da ligação tipo KK baseado na deformação diametral do banzo. O modo de falha 1 ocorre quando um par de diagonais vizinhas, carregadas no mesmo sentido, empurra ou puxa, a parede do banzo e no segundo, chamado modo 2 acontece uma deformação diametral da parede do banzo na região entre as diagonais vizinhas, criando quinas e dobras entre essas diagonais. Outro objetivo é estabelece uma demarcação do limite entre os dois modos de falha como uma função do afastamento transversal entre as diagonais. Os resultados permitiram o desenvolvimento de equações que preveem as resistências das ligações tipo KK, para os modos de falha 1 e 2 (plastificação da parede do banzo), a partir da resistência da ligação tipo K correspondente
Abstract: This work presents a parametric study of K and KK tubular steel connection. Gap connections with symmetric loading are analyzed. A numerical model using the commercial finite element software Ansys is proposed to compare K and KK connection resistances. Two auxiliary softwares are developed for setting the numerical model and to post-process results. A set of 55 KK connections and their correspondent K connections are analyzed and their resistances are compared. The objective of this work is purpose define the failure mode (1 or 2) of KK connections. This criteria is based on the chord diametric deformation. The results allowed the definition of limit values in function of the transversal gap for determining the connection failure mode. The connection resistance obtained in the parametric study allowed the development of an analytical expression which predict the KK connections resistance from the resistance of its correspondent K connection

Performing artists have frequently used technology to sense and extend the body's natural expressivity via live control of multimedia. However, the sophistication, emotional content, and variety of expression possible through the original physical channels of voice and movement are generally not captured or represented by these technologies and thus cannot be intuitively transferred from body to digital media. Additionally, relevant components of expression vary between different artists, performance pieces, and output modalities, such that any single model for describing movement and the voice cannot be meaningful in all contexts. This dissertation presents a new framework for flexible parametric abstraction of expression in vocal and physical performance, the Expressive Performance Extension Framework. This framework includes a set of questions and principles to guide the development of new extended performance works and systems for performance extension, particularly those incorporating machine learning techniques. Second, this dissertation outlines the design of a multi-layered computational workflow that uses machine learning for the analysis and recognition of expressive qualities of movement and voice. Third, it introduces a performance extension toolkit, the Expressive Performance Extension System, that integrates key aspects of the theoretical framework and computational workflow into live performance contexts. This system and these methodologies have been tested through the creation of three performance and installation works: a public installation extending expressive physical movement (the Powers Sensor Chair), an installation exploring the expressive voice (Vocal Vibrations), and a set of performances extending the voice and body (Crenulations and Excursions and Temporal Excursions). This work lays the groundwork for systems that can be true extensions of and complements to a live performance, by recognizing and responding to subtleties of timing, articulation, and expression that make each performance fundamentally unrepeatable and unique.

A parametric array exploits the nonlinearity of the propagation medium to emit or detect acoustic waves in a spatially versatile manner, permitting concise, narrow directivity patterns otherwise possible only with physically very large transducer geometries. This thesis explores the use of the parametric array as an audible sound source, permitting audible sound to be generated with very high directivity compared to traditional loudspeakers of comparable size. The thesis begins with a review of basic underlying mathematics and relevant approximate solutions of nonlinear acoustic systems. Then, these solutions are used to construct suitable methods of ultrasonic synthesis for low-distortion audio reproduction. Geometrical modelling methods for predicting the acoustic distribution are presented and evaluated, and practical applications are explored experimentally. Issues of risk associated with ultrasonic exposure are presented, and the feasibility of a phased-array system for beam control is explored.

In light of recent military budget cuts, there has been a recent focus on determining methods to reduce the cost of Navy ships. A RAND National Defense Research Institute study showed many sources of cost escalation for Navy ships. Among them included characteristic complexity of modem Naval ships, which contributed to half of customer driven factors. This paper focuses on improving the current parametric cost estimating method used as referenced in NAVSEA's Cost Estimating Handbook. Currently, weight is used as the most common variable for determining cost in the parametric method because it's a consistent physical property and most readily available. Optimizing ship design based on weight may increase density and complexity because ship size is minimized. This paper will introduce electric power density and outfit density as additional variables to the parametric cost estimating equation and will show how this can improve the early stage cost estimating relationships of Navy ships.

Dentre os processos de conformação mecânica de metais por deformação plástica, a estampagem possui grande importância por possibilitar a obtenção de produtos de diversos formatos, semi-acabados ou acabados e com boas propriedades mecânicas. A simulação computacional utilizando o método dos elementos finitos apresentou um grande desenvolvimento na última década, hoje é uma importante ferramenta de análise de projetos. Neste trabalho é apresentada a elaboração de um arquivo paramétrico, em linguagem APDL, de simulação do processo de estampagem de copos cilíndricos para o programa comercial ANSYS® 7.0. Este arquivo é construído de maneira automática por um programa criado no software de programação DELPHI 7.0. O paramétrico irá auxiliar o projetista na análise das variáveis do processo de estampagem e no desenvolvimento de ferramental, permitindo realizar um estudo dessas variáveis de maneira isolada ou com vários fatores simultâneos.

The use of CAM system to create tool s trajectories in outline of simple

program requires a solid knowledge in CN programming and the results referring to
CNC machine s performance are directly connect to the way of programming to
obtain these results. The aim of this study was to develop a practice s analysis
between parametric program and a CAM system in a specific CNC machine, based
on acting time and speed of tool s progress to each programming method. The
counting of time was accomplished through CNC controller, which shows the
execution time of each program from its beginning until receiving or reading the stop
command. The comparison between these programming methods created results
that depend of the programming way, but who receive interference of controller s
technologies recourses to put in action the CNC axis machine. With these testing, it
was possible to demonstrate, by means of parametric programs, an increase of 65%
in performance, when compared to other programming methods.A utilização de sistemas CAM para a geração de trajetórias de ferramenta em contornos de geometria simples depende diretamente do conhecimento e da capacidade do usuário na alimentação das informações e na utilização dos recursos disponíveis desses sistemas. A programação paramétrica exige uma base sólida no conhecimento da programação CN e os resultados que se referem ao desempenho da máquina CNC estão diretamente ligados à forma de programação para a obtenção desses resultados. O objetivo deste estudo foi desenvolver uma análise de desempenho entre a programação paramétrica e um sistema CAM em uma máquina CNC específica, com base nos tempos de execução e velocidade de avanço da ferramenta para cada método de programação. A contagem de tempo foi realizada através do controlador CNC, que indica o tempo de execução de cada programa a partir do seu início até o recebimento ou leitura do comando de parada. A comparação entre esses métodos de programação gerou resultados que dependem diretamente da forma de programação, mas que recebem interferência dos recursos tecnológicos do controlador para o acionamento dos eixos da máquina CNC. Com essas experimentações, foi possível demonstrar, através de programas paramétricos, um aumento no desempenho em até 65% quando comparado a outros métodos de programação.

Pełny tekst źródłaStreszczenie:
One of the early steps in axial turbine design is the use of one-dimensional (1D) mean line calculations to predict the turbine performance and estimate the principal geometric parameters, such as radius and blade heights, that will be needed in further computational fluid dynamic (CFD) studies. This 1D analysis is based on the estimation of the aerodynamic losses expressed as a function of simple blade parameters and the velocity triangles. In this regard, there exist different loss correlations widely used in literature to estimate these losses but at the same time there is a lack of information regarding differentiation between them. Thereafter, the objective in this work was to judge and compare the behaviors of the Kacker- Okapuu, Craig-Cox and Denton loss correlations, all of them widely-used in turbine performance prediction. Present work shows the implementation of these different loss correlations on an existing 1D mean line numerical tool, LUAX-T. Subsequently, once implemented, the correlations were compared and analyzed by the use of a validation process and performing a parametric study. The results show that similar key parameters such as the flow turning, solidity and aspect ratio rule the different loss mechanisms in each correlation. On the other hand, the parametric study shows that the correlations are in agreement with the theory and give similar trends for performance prediction even though they all predict different values of efficiency for the same turbine stage. Moreover, the validation process show the correlations were found to be accurate enough when comparing against two different sets of experimental data. However, it was also proved that the models are only accurate if used within the range of applicability they were developed for, hence a complete knowledge of the limitations of each correlation should be known prior to using them. Finally, the extension of the one-dimensional mean line numerical tool LUAX-T will serve to perform further studies related to turbine design, as there are very few non-confidential turbomachinery design tools available for teaching or researching. Furthermore, a parametric study tool was also developed as part of the program. This last extension and the loss implementation codes are described in this work.

Este trabalho tem como objetivo explorar a forma de planos de fachada vinculados à incidência solar, potencializando a aplicação de sistemas fotovoltaicos. A identificação e parametrização de formas segundo os princípios geométricos de captação fotovoltaica, sugerem a aplicação de uma metodologia de projeto para superfícies de fachadas fotovoltaicas, de modo a otimizar a incidência direta da radiação solar, incorporada a volumetria da edificação. O modelo de otimização de fachadas fotovoltaicas consiste em quatro etapas. Inicialmente define-se a tecnologia fotovoltaica e a localização geográfica (1). Posteriormente, é realizada a modelagem elementar tridimensional (2) através do editor de algoritmos gráficos Grasshopper – integrado à ferramenta de modelagem Rhinoceros3D – estabelecendo assim, as restrições e variáveis da forma. Na terceira etapa, correlacionamse transformações geométricas tridimensionais (twist, taper e shear) e incidência solar (3) por meio dos softwares Ecotect Analysis e Grasshopper. Com isso, os parâmetros dimensionais atribuídos às variáveis – transformações geométricas – são vinculados aos parâmetros de radiação solar, visando à geração de formas. Após a seleção das formas com maior potencial fotovoltaico, identificam-se as zonas com maior incidência de radiação solar e realiza-se a manipulação dos pontos de controle das superfícies NURBS (4). Através das transformações geométricas taper, shear e twist foi possível gerar um conjunto de soluções otimizadas, correlacionando dados energéticos e geométricos, integrando métodos de geração de formas e avaliação performática da radiação solar. O estudo identificou que as possibilidades de articulação entre os planos fotovoltaicos e a eficiência energética têm implicações positivas, correlacionando variabilidade formal e geração de energia elétrica.This work aims explore the shape of façade planes linked to the solar incidence, in order to optimize the use of photovoltaic systems. The identification and parameterization of forms according to geometric principles of photovoltaic capture suggest the application of a design methodology for optimizing the photovoltaic surface façade in order to optimize direct solar radiation, incorporating the volume of the building. The optimization model of photovoltaic façade consists of four steps. Initially decide on the photovoltaic technology and geographic location (1). Subsequently, three-dimensional elementary modeling is performed (2) through the graphic-algorithm editor, Grasshopper, – integrated with the modeling tool, Rhinoceros 3D, – thus establishing, restrictions and variables in shape. In the third stage, threedimensional geometric transformations are correlated (twist, taper and shear) and solar incidence (3) through the computer interfaces of Ecotect Analysis and Grasshopper software. With this, the dimensional parameters assigned to the variables – geometric transformations – are linked to parameters of solar radiation, in order to generate shapes. After the selection of potential photovoltaic shapes, zones with the greatest incident solar radiation are identified and the control points of NURBS surface are manipulated (4). Using the geometric transformations taper, shear and twist, it was possible to generate a set of optimal solutions, correlating geometric and energetic data, integrating shape generating methods and performatic evaluation of solar exposure. The work identified that possibilities of articulation between photovoltaic planes and energetic efficiency have positive results, correlating shape variability and electricity generation.

Resumo: Este projeto tem o objetivo de estudar o efeito dos principais parâmetros que afetam a solução do problema de contato entre corpos elásticos. Foi utilizado o software comercial ANSYS 11.0 para realizar as análises de contato. A influência dos principais parâmetros considerados pelo ANSYS no problema de contato, tais como a rigidez de contato normal, o limite de penetração, os algoritmos de contato e métodos de solução, é investigada no trabalho. Observou-se que a rigidez de contato normal influi diretamente na convergência e nos resultados obtidos. Foram estudados alguns exemplos com resultados conhecidos (analíticos ou numéricos) para uma comparação com a solução do ANSYS, e exemplos de maior interesse prático, como o problema de contato do olhal menor de uma biela automotiva. A partir dos casos analisados, algumas recomendações foram feitas para a escolha dos parâmetros de contato. No entanto, existem parâmetros que dependem do conhecimento do usuário ou da realização de testes preliminares, o que requer em muitas situações um maior tempo para se obter os resultados. Como alternativa, foi investigado o potencial das redes neurais para contornar esta limitação. As redes neurais foram treinadas com resultados obtidos da solução do problema de contato (penetração e variação da pressão de contato) de modelos simplificados, tendo como saída da rede a rigidez de contato normal, que é então usada para estimar a rigidez de contato normal de problemas mais complexos. Foi usada a implementação de redes neurais do software MATLAB 7.0 para o treinamento e a simulação das redes neurais
Abstract: The objective of this project is to study the effect of the main contact parameters that affect the solution of the elastic bodies contact problem. The commercial software ANSYS 11.0 was used to run the contact analysis. The influence of ANSYS main parameters in the contact problem, such as normal contact stiffness, penetration limit, contact algorithms and solvers, is investigated in this work. The normal contact stiffness acts directly in convergence and in the obtained results. Some examples with known results (analytic or numeric) were studied to be compared with ANSYS solution, and some examples of more practical interest, as the connecting rod small end contact problem, were also studied. With the analysed cases, some recommendations were done to the choice of the contact parameters. However, there are parameters that depend on the user's knowledge or it is necessary to run some preliminary tests. As an alternative, it was investigated the neural networks potential to overcome this limitation. The neural networks were trained with obtained results of the contact problem solution (penetration and contact pressure variation) of simplified models. The normal contact stiffness was used as output of the network, which was used to estimate the normal contact stiffness of more complex problems. It was used the neural network implementation of the softwareMATLAB 7.0 to the training and simulation of the neural networks

RESUMO
Uma das formas mais eficientes de se estabelecer medidas de controle da erosão hídrica e conhecer os efeitos conjugados dos mecanismos naturais que atuam no seu processo, é a predição através de modelos matemáticos. Um destes modelos é o modelo WEPP - Water Erosion Prediction Project, eminentemente determinístico, baseado em estruturas físicas e matemáticas. Além da concepção física que lhe confere maior complexidade, este modelo diferencia-se dos demais por considerar, na dinâmica de destacamento, transporte e deposição, os processos de erosão em sulcos e entre sulcos, com três parâmetros de erodibilidade distintos: Ki, erodibilidade entre sulcos; Kr, erodibilidade em sulcos; e tauc, tensão crítica de destacamento de partículas do solo pelo fluxo. A utilização do modelo na predição de erosão necessita da calibração destes três parâmetros de erodibilidade, que são intrínsecos a cada tipo de solo. Sua estimativa é, normalmente, feita através de chuvas simuladas. Porém o uso de técnicas de otimização em hidrologia tem sido comum e constitui-se em uma forma eficiente de estimativa de parâmetros em diversos tipos de modelos. A proposta deste trabalho foi a otimização para a calibração destes parâmetros para uma condição edafo-climática do Paraná, utilizando dados básicos de solo, topografia, clima e manejo de parcelas padrão sem cobertura do IAPAR - Instituto Agronômico do Paraná, na cidade de Ponta Grossa. Os resultados apontam problemas para a calibração destes parâmetros em decorrência da própria estrutura do modelo. O valor encontrado de Ki na calibração foi de 562.500 Kg/s.m4 Embora a eficiência das calibrações tenha atingido o valor de 0,786, para os valores de Kr e tauc de 0,0236 s/m e 1,19 N/m2, respectivamente, as diversas tentativas de calibração de Kr e tauc resultaram em múltiplas alternativas de combinação de valores destes parâmetros para uma mesma perda de solo de um evento e em todos os eventos, indicando que a eficiência encontrada é relativa, havendo necessidade de determinação de tauc a campo ou a alteração da estrutura do modelo ( no parâmetro Kr) para que as chuvas naturais possam ser utilizadas nas calibrações através de técnicas de otimização.

Previous issue date: 2010-11-30Producing more in less physical space and in less time, increasing the profitability and reducing sanitary and economical risks are some of the challenges of the Brazilian livestock that the intensive breeding aims to supplant. A considerable increase in the number of confining unities as well as in feedlot cattle is already observed, thus, the attention to the control of pathological alterations deriving from the production intensification that can compromise the profitability and the economical viability of such activities should also increase. Considering the context presented herein, this essay aimed to analyze the economical/sanitary viability of the usage of florfenicol (40 mg/kg) in the metaphylaxis of bovine respiratory diseases (BRD) in feedlot cattle in the state of Goiás, where two groups totalizing 125 animals were concurrently monitored during 100 days. The first group, having 32 animals, was maintained under the standard sanitary protocol of the confining groups and it was called control (G1). The second group, having 93 animals, was submitted to metaphylaxis with florfenicol (40 mg/kg) at the beginning of the confinement and it was called metaphylaxis (G2). In the both groups, the sanitary and the productive standards were evaluated and a financial analysis was performed in order to economically validate the method. The animals were examined, weighted and materials for analyses were collected at the beginning and at the end of the confinement, when the occurrence of respiratory problems in the animals was evaluated. The animals submitted to metaphylaxis with florfenicol had a daily weight gain (DWG) superior to the one of the animals pertaining to the control group, and the indexes of BRD demonstrated through the analysis of the method viability (MV) were superior to 2.7%, which justifies the investment in the prevention of BRD.
Produzir mais em menor espaço físico e em menor tempo, incrementando a lucratividade e reduzindo os riscos sanitários e econômicos são alguns dos desafios da pecuária brasileira que a criação intensiva procura suplantar. Já se observa considerável aumento no número de unidades confinadoras, bem como de animais confinados; e do mesmo modo, cresce a atenção ao controle das alterações patológicas decorrentes da intensificação da produção e que possam comprometer a lucratividade e a viabilidade econômica da atividade. Considerando este cenário, o presente trabalho pretendeu analisar a viabilidade econômico/sanitária da utilização do florfenicol (40mg/Kg) na metafilaxia da doença respiratória bovina (DRB) em bovinos confinados no estado de Goiás, onde foram acompanhados concomitantemente durante o período de 100 dias dois grupos com 125 animais. O primeiro grupo foi mantido sob o protocolo sanitário padrão do grupo confinador e com 32 animais foi designado controle (G1). O segundo grupo, com 93 animais foi submetido à metafilaxia com florfenicol (40mg/Kg) a entrada do confinamento e designado metafilaxia (G2). Em ambos os grupos foram avaliados padrões sanitários e produtivos, também foram realizadas análises financeiras para a validação econômica do método. Os animais foram examinados, pesados e colhidos materiais para análise na entrada e saída do confinamento, período em que se avaliou a ocorrência de problemas respiratórios nos animais. Foi observado que os animais submetidos à metafilaxia com florfenicol tiveram um ganho de peso diário (GPD) superior aos animais do grupo controle, e os índices de DRB demonstrados por meio da análise de viabilidade do método (VM) foram superiores a 2,7%, justificando o investimento na prevenção da DRB.

Le concept de gouvernance appréhendée par la Banque mondiale au milieu des années 1980, apparaît comme une préoccupation majeure au niveau de l’analyse du développement économique. Il est de plus en plus présent dans les débats sur la recherche de solides fondements de la croissance économique, notamment la croissance économique de long terme dans les pays en voie de développement. La résurgence de la pauvreté après la mise en œuvre des programmes d’ajustement structurel, la persistance des inégalités en Afrique subsaharienne, l’importance des ressources naturelles dont dispose ces pays, et la volonté manifestée récemment par les Chefs d’Etat de ces pays, d’engager leurs pays respectifs à l’initiative de transparence dans les industries extractives (ITIE), suscitent de nombreux enjeux, auxquels seule leur capacité à conduire la bonne gouvernance leur mettra en position de réaliser une croissance économique capable de réduire les inégalités. L’objectif principal de cette thèse est d’analyser le rôle des institutions dans la détermination de la croissance économique en Afrique au Sud Sahara et en diagnostiquant l’influence d’autres variables anthropo-sociologiques telle que la fragmentation ethnique sur la trajectoire de la croissance économique. En utilisant des techniques économétriques et statistiques adéquates et pertinentes, nous arrivons dans un premier temps à montrer qu’il existe une relation positive et très significative entre l’ensemble des variables de gouvernance (Ecoute des citoyens et reddition des comptes ; Stabilité politique et absence de violence ; Efficacité des pouvoirs publics ; Qualité de la réglementation ; Règle de Loi ou Etat de droit ; Maitrise de la corruption) et le taux de croissance du PIB par tête des pays en Afrique au Sud du Sahara. De plus, Cette croissance du PIB par tête est beaucoup plus importante pour les pays colonisés par l’Angleterre et moins favorable pour ceux colonisés par la France. On est tenté à ce stade de l'analyse de lier la qualité des institutions des pays africains à celle des pays colonisateurs. Dans un second temps, l’étude a révélé qu’il n’y a pas de relation linéaire entre le taux de croissance du PIB par tête et les variables mises en évidence. De plus, en présence de la variable« Ethnie », les variables de gouvernance n’ont pas d’influence fondamentale sur la croissance économiquedes pays en Afrique au Subsaharienne. Néanmoins, une relation positive et très significative entre la variable « Ethnie » et le taux de croissance du PIB par tête a été mise en évidence. Enfin, ce travail nous a permis d’apprécier la qualité des institutions et des systèmes de contre-pouvoir notamment l’implication des Organisations de la Société Civile dans la définition et la mise en œuvre des politiques et programmes de développement au Tchad à partir de l’analyse de l’état de la gouvernance économique et financièreThe concept of governance initiated by the World Bank in the mid-1980s appears to be a major concern in the analysis of economic development. It is increasingly present in the debate on finding a solid foundation for economic growth, particularly long-term economic growth in developing countries. The resurgence of poverty following the implementation of structural adjustment programs, the persistence of inequality in sub-Saharan Africa, the abundance of natural resources available to these countries and the clear willingness lately shown by the Heads of State of these countries, to commit their respective countries to the Extractive Industries Transparency Initiative (EITI), raise many issues, to which only their capacity to upload good governance will enable them to attain an economic growth that can reduce levels of inequality. The main objective of this thesis is to analyze the role of institutions in determining economic growth in Africa South Sahara and diagnosing the influence of other anthropological - sociological variables such as ethnic fractionalization in the path of the economic growth. Using appropriate econometric techniques and relevant statistics, we reach first to show that there is a positive and highly significant relationship between all governance variables (Citizen Voices and Accountability, Political Stability and Absence of Violence, Government Effectiveness, Regulatory Quality, Rule of Law or State of Law, Control Corruption) and the GDP growth rate per capita of the countries in Africa south of the Sahara. In addition, the growth of GDP per capita is much more important for countries colonized by England and less favorable to those colonized by France. One is tempted at this stage of the analysis to link the quality of the institutions of the African countries to that of the colonizing countries. Secondly, the study found that there is no linear relationship between the growth rate of GDP per capita and variables highlighted. Moreover, in the presence of the variable " Ethnic ", the governance variables do not have a fundamental influence on economic growth of the countries in Sub-Saharan Africa. Nevertheless, a positive and highly significant relationship between the variable " Ethnic " and the GDP growth rate per capita was highlighted. Finally, this work has allowed us to appreciate the quality of institutions and systems against power including the involvement of civil society organizations in the definition and implementation of the development of policies and programs in Chad from the analysis of the state of the economic and financial governance

Este estudo corresponde a um balanço historiográfico da pesquisa que elegeu o tempo histórico no ensino de História como objeto de investigação na década passada. A partir de uma aproximação com autores cujas reflexões apontam ruptura com a história linear e desconstrução da idéia de progresso como norma histórica em defesa de uma concepção do tempo histórico fundada nas experiências concretas dos sujeitos, procura (re)construir sentidos da experiência que constitui o tempo histórico como campo de pesquisa específico e que envolve a História e suas interlocuções com outras áreas do conhecimento. Caracterizadas segundo seus objetivos, suas abordagens teórico-metodológicas e suas conclusões, as pesquisas revelaram que o objeto tempo histórico se constitui com base em diferentes possibilidades de investigação, seja na perspectiva de se apreender como os alunos compreendem, desenvolvem e/ou representam noções temporais, seja na perspectiva dos pesquisadores que se preocupam com o lugar do tempo histórico nas propostas curriculares, na formação e nas representações dos professores, bem como no livro didático de História. O diálogo indagativo com as pesquisas ensejou uma reflexão sobre a inserção dos Parâmetros Curriculares Nacionais como via de interlocução entre políticas públicas adotadas para a educação no Brasil e a produção acadêmica; sobre fundamentos, perspectivas e questões relativas à proposta de uma educação histórica; também pôs em questão a idéia de progresso como força motriz de uma concepção linear de história
Abstract: TURINI, Leide Divina Alvarenga. O tempo histórico na pesquisa sobre ensino de História. Um balanço historiográfico. 2006. Tese (Doutorado em Educação) ¿ Faculdade de Educação da Universidade Estadual de Campinas, Campinas, 2006. This study corresponds to a historiographical examination of the research which elected historic time in the History teaching as subject matter last decade. It tries to rebuild meanings of the experience constitutive of historic time as a specific research field involving history and its intersection with other fields of knowledge, based on authors who point out a rupture in the linear history and deconstruction of the idea of progress as a historical norm and, so, support a conception of historic time founded on the individuals¿ concrete experience. Given their goals, theoretical, methodological approaches, and conclusions, these researches have revealed that historic time as subject matter is constituted according to different possibilities of investigation, whether it is into the perspective of grasping how students understand, develop, and represent time notions or into the perspective of researchers worried about the place historic time occupies in curricular proposals, in teachers¿ education and representations, as well as in History textbooks. The enquiring dialogue with these researches aimed to supply a reflection on both the presence of the national curriculum guidelines in them ¿as a way of interlocution between public policies for education in Brazil and the academic production¿and on the grounds, perspectives, and questions related to the proposition of a historical education. Also, it put into question the idea of progress as motive force of a linear conception of history

Resumo: Em 2001 desenvolvemos um método de avaliação do senso rítmico em pessoas com surdez de severa a profunda. Neste método utilizamos um sistema de dicas visuais como forma de substituir as dicas sonoras (não perceptíveis ao surdo) que dão informação sobre o ritmo ambiental e que gerenciam a realização de um movimento no ritmo. O programa de atividades rítmicas adaptadas (P.A.R.A) foi aplicado num período de quatro meses e propunha fazer com que os sujeitos participantes fossem estimulados a perceber o ritmo ambiental (música tocada) em seu parâmetro velocidade, através do uso de dicas visuais. Eram dispostos em um quadro imantado oito imãs com o desenho de tartarugas para compreensão do ritmo lento e coelhos para a compreensão do ritmo rápido. A disposição destas figuras no quadro imantado, chamamos de estruturas. O pesquisador tocava com as mãos na estrutura (figura por figura, na ordem de 1 a 8) na velocidade do ritmo que estava presente no ambiente, solicitando aos sujeitos que realizassem movimentos previamente orientados no ritmo que estava sendo visualmente demonstrado ao grupo. Esta pesquisa revelou que o surdo que participou do P.A.R.A apresentou melhores resultados em suas performances nos parâmetros de velocidade do ritmo do que os surdos que não se utilizam do sistema de dicas visuais para compreensão do ritmo externo (ambiental). Porém, a disseminação do programa dependia da habilidade do professor na execução dos toques com a mão na estrutura dentro de um padrão rítmico, restringindo a possibilidade de levar o programa a outros surdos, dada a especificidade do conhecimento nas questões do ritmo que a pessoa que orienta o programa deveria ter. A proposta da presente pesquisa foi a de desenvolver um método que propicie ao surdo maior autonomia frente a estas questões do ritmo, onde ele mesmo visualize o ritmo externo, sem o auxílio de um intermediador, para tanto foram desenvolvidos dois softwares que tem por função mostrar ao surdo através da percepção visual e/ou da percepção tátil, qual o ritmo que está sendo tocado no ambiente como orientador de suas ações motoras rítmicas. Trata-se de uma pesquisa quase experimental com delineamento ex post facto 4 x 2 onde utilizamos um teste não paramétrico de Kruskal Wallis, para amostras independentes entre si.O objetivo era analisar a interferência dos métodos utilizados com diferentes instrumentos, nos testes do padrão rítmico na performance rítmica dos sujeitos da pesquisa. Os sujeitos foram distribuídos em quatro grupos distintos, segundo as ferramentas utilizadas no teste: G1.Com o uso das estruturas rítmicas; G2.Com o uso apenas das dicas visuais na interface do computador;G3. Com o uso apenas do celular com o estímulo tátil (vibratório) e G4. Com o uso dos dois softwares ("no computador" com a dica visual e "no celular" com o modo vibratório). Os resultados apontaram para diferenças não significativas quanto ao uso de diferentes métodos de dicas (tátil ou visual) para realização de movimentos dentro do padrão rítmico, com um p=0,2119 para o ritmo lento e p=0,2891 para o ritmo rápido com um _=0,05. As médias obtidas nos testes evidenciaram a eficácia do uso de dicas, sejam elas visuais ou táteis na realização dos movimentos solicitados dentro dos parâmetros de velocidade (lento e rápido) do ritmo, sugerindo a viabilidade da utilização do uso dos softwares BPM (Batidas Por Minutos) e VPM (Vibrações Por Minuto) no Programa de Atividade Rítmica Adaptada ao surdo.
Abstract: In 2001 we developed a method of evaluation of the rhythmic sense in people with severe and deep hearing problems. In this method we use a system of visual clues as a way of replacing sound clues (which a deaf individual cannot perceive) that provide pieces of information about the environmental rhythm and manage the performance of a movement in rhythm. The Program of Adapted Rhythmic Activities (PARA) was applied in a four months period and its aim was making the participant individuals be stimulated to perceive the environmental rhythm (played song) in its speed parameter, through the use of visual clues. In a magnetic board we placed eight magnets with turtle drawings for the understanding of slow rhythm and rabbits for the understanding of the fast rhythm. We call the disposition of these figures on the magnetic board structures. The researcher touched the structure with his hands (one by one in order from 1 to 8) in the speed of the environmental rhythm, asking the individuals to perform previously oriented movements in the rhythm that has been visually demonstrated to the group. This research showed that the deaf who participated in PARA presented better results in his performance than those who do not use the system of visual clues to comprehend the internal rhythm (environmental). However, the dissemination of the program depended on the ability of the teacher in performing hand touches in the structure within a rhythmic pattern, limiting the possibility of taking the program to other deaf, given the specificity of the knowledge in rhythmic issues that the person who oriented the program should have. The proposal of the present research was to develop a method that provides the deaf grater autonomy before these rhythmic issues, in which he himself visualize the external rhythm, without the help of a intermediary, to do so we developed two pieces of software that have the function of showing the deaf through visual and/or tactile perception which rhythm is being played in the environment as a guide for his motor rhythmic actions. This is an almost experimental research with a lay out post facto 4 x 2 in which we used a nonparametrical test from Kruskal Wallis, for independent samples among them. The aim was to analyze the interference of the method used in the tests of rhythmic pattern in the rhythmic performance of the participants of the research. The participants were distributed in four different groups, according to the tools used in the test: G1 with the use of rhythmic structures; G2 with the use of only a cell phone with a tactile stimulus (vibration); G3 with the use of only visual clues in the interface of a computer and G4 with the use of both pieces of software ("on the cell phone" with the vibration mode and "on the computer" with visual hint). The results pointed to non-significant differences regarding the use of different clues (tactile or visual) methods to perform movements within the rhythmic pattern with a p=0,2119 to slow rhythm and p=0,2891 to the fast rhythm, and _=0,005. The averages obtained in the test demonstrated the efficiency of the use of clues, either visual or tactile in the performance of the requested movements within the speed parameters (slow and fast) of rhythm, suggesting the viability of the use of BPM (Beats per Minute) and VPM (Vibrations per Minute) pieces of software in the Program of Adapted Rhythmic Activities for the Deaf.

Cette thèse traite de l'étude analytique et numérique des surtensions de manoeuvre d'un réseau électrique comportant un transformateur à vide raccordé à l'extrémité d'une ligne de transport. Ce traitement permet d'établir des règles aussi simples que possibles pour identifier et éviter des manoeuvres dangereuses, lorsqu'il s'agit par exemple de remettre sous tension un réseau à l'issue d'un incident. Dans une première partie, une analyse de l'ensemble des surtensions de manoeuvre sur la ligne à vide est rappelée, puis une extension du problème avec transformateur à vide à son extrémité est considérée. Dans une deuxième partie, une configuration monophasés simple mais représentative d'un cas réel a été définie permettant d'effectuer une étude analytique des surtondons aux bornes du transformateur. Les résultats obtenus dans le cas linéaire comme dans le cas non linéaire sont qualitativement représentatifs. Ensuite, une simulation numérique triphasée a été réalisée à l'aide du logiciel Morgat. Pour cela, nous avons développé des sous-programmes de gestion des valeurs d'entrée et des résultats simulés permettant d'enchaîner les simulations en modifiant un ou plusieurs paramètres de manière déterministe ou statistique associée à un générateur aléatoire. Les paramètres ayant une influence importante ont été analysés et seuls trois d'entre eux ont été retenus : la fréquence propre du réseau vue des bornes du transformateur, la puissance de la source et la puissance du transformateur cible. L'une des conclusions auxquelles on aboutit est que le rapport des puissances transformateur cible et source doit être adapté si on désire limiter les surtensions. Enfin, une étude statistique de la fermeture aléatoire des trois pôles du disjoncteur autour d'une valeur moyenne a été faite. Ceci nous a permis de définir un critère simplifié caractérisant le domaine des surtensions admissibles en fonction des paramètres d'influence

I byggbranschen har nya metoder för projektering utvecklats genom införandet av moderna och mer kraftfulla BIM-verktyg. Flera av dagens konstruktioner modelleras enligt tredimensionella principer.Tekla Structures är ett kraftfullt BIM-verktyg som klarar av att hantera både huskonstruktioner och anläggningskonstruktioner. Trots detta kan programmet inte hantera broar med dubbelkrökning på ett effektivt sätt. Projektörer behöver därför utgå från flera program för att kunna hantera komplexa brokonstruktioner.För att kunna utnyttja fördelar med Tekla Structures, behöver programmet att utvecklas eller kompletteras med andra tredjepartsprogram. Detta projekt syftar till att integrera nya arbetssätt och införa en metodik, i form av parametriserade modellering i Tekla Structures. En sådan form av modellering tillåter användaren att modifiera parametrar för en önskad modell.Ett skript är skapad genom ett visuellt programmeringstillägg, som genererar parametriskbaserade bromodeller. Brokonstruktionstyp som modellerades i detta projekt är en plattrambro.Resultatet av projektet pekar mot att parametriserad modellering är ett effektivt sätt att modellera och en lösning för att bland annat hantera broar med dubbelkrökningar.New methods for project designing in the building construction industry have been developed by introducing modern and powerful BIM tools. Several of today’s constructions are designed according to three-dimensional principles.Tekla Structures is a powerful BIM tool that is capable of managing both house and infrastructure constructions. Despite this, the program cannot handle bridges with a horizontal and vertical curvature efficiently. The designers must instead rely on several other applications to manage complex bridge constructions.In order to use the advantages of Tekla Structures, the software needs to be evolved or complimented by other third party softwares. This project aims to integrate new working technics and introduce a method based on parametric design in Tekla Structures. Such form of modeling enables the modification of parameters to a desired model for the user.A script is created through a visual programming extension that generates a parametric based bridge models. The bridge type in this project was designed, is an integral bridge.The project has proved that parametric based design is more effectively and a solution to manage bridges with horizontal and vertical curvature.

This work deals with a design of hypokinetic dysarthria analysis system. Hypokinetic dysarthria is a speech motor dysfunction that is present in approx. 90 % of patients with Parkinson’s disease. The work is mainly focused on parameterization techniques that can be used to diagnose or monitor this disease as well as estimate its progress. Next, features that significantly correlate with subjective tests are found. These features can be used to estimate scores of different scales like Unified Parkinson’s Disease Rating Scale (UPDRS) or Mini–Mental State Examination (MMSE). A protocol of dysarthric speech acquisition is introduced in this work too. In combination with acoustic analysis it can be used to estimate a grade of hypokinetic dysarthria in fields of faciokinesis, phonorespiration and phonetics (correlation with 3F test). Regarding the parameterization, features based on modulation spectrum, inferior colliculus coefficients, bicepstrum, approximate and sample entropy, empirical mode decomposition and singular points are originally introduced in this work. All the designed techniques are integrated into the system concept in way that it can be implemented in a hospital and used for a research on Parkinson’s disease or its evaluation.

The subject matter of the master´s thesis is, in particular, an evaluation of the advantageousness of the construction of a pumped-storage hydroelectric power station in the vicinity of Cukrová Bouda. In the master´s thesis introduction the utilisation of pumped-storage hydroelectric power stations in providing reserve power generation to the operator of a power transmission system is discussed. The thesis then focuses on a technical design solution where two alternatives are drawn up for which the nominal parameters of individual designs for a pumped-storage hydroelectric power station are specified. The following part deals with the impact of the structure and the plant’s subsequent operation on the environment. A further key part is the determination of investment and subsequent operating costs and an evaluation of the plant according to economic pointers. The final part of the master´s thesis contains a SWOT analysis and an assumed programme of works for the plant’s preparation and actual construction. The conclusion contains an overall evaluation.

Haque, Inzemamul. "Verification of a Generative Separation Kernel". Thesis, 2020. https://etd.iisc.ac.in/handle/2005/4571.
Pełny tekst źródłaStreszczenie:
A Separation Kernel is a small specialized microkernel that provides a sand-boxed execution environment
for a given set of processes (also called \subjects"). The subjects may communicate
only via declared memory channels, and are otherwise isolated from each other. A generative
separation kernel is one in which a specialized separation kernel is generated for each system
con figuration. Separation kernels are typically used in safety-critical and security-critical systems
in the avionics and military domains, and it is of utmost importance to have a high level
of assurance regarding the correct working of the separation kernel.
In this thesis we present a formal veri fication of the functional correctness of the Muen
separation kernel which is representative of the class of modern separation kernels that leverage
hardware virtualization support and are generative in nature. The nature of generativeness is
template-based, in that the kernel is essentially based on a fixed template of code and various
constant data-structures are filled-in by the kernel generator. Although there is a great deal
of work in verifi cation of OS kernels in the past two decades, applying those techniques to a
separation kernel like Muen becomes challenging because of its generative nature. The use of
hardware virtualization support poses another challenge.
We propose a veri fication framework called conditional parametric re finement to reason
about the functional correctness of template-based generative systems. Conditional parametric
re finement extends classical re finement to parametric programs which are programs with
uninitialized variables. This is a two-step technique for parametric programs. We first perform
a general verifi cation step (independent of the input spec) to verify that the parametric
program re fines a parametric abstract specifi cation, assuming certain natural conditions on the
parameter values (for example injectivity of the page tables) that are to be fi lled in. This first
step essentially tells us that for any input speci fication P, if the parameters generated by the
system generator satisfy the assumed conditions, then the generated system is correct vis-a-vis
the abstract specifi cation. In the second step, which is input-speci fic, we check that for a given
input speci fication, the assumptions actually hold for the generated parameter values. This
gives us an effective veri fication technique for verifying generative systems.
We applied this technique to verify the Muen Separation Kernal. We chose to model the
virtualization layer (in this case Intel's VT-x layer) along with the rest of the hardware components
like registers and memory, programmatically in software. We carried out the first step of
conditional parametric refi nement for Muen, using the Spark Ada veri fication tool. The effort
involved about 20K lines of source code and annotation. We have also implemented a tool that
automatically and effciently performs the Step 2 check for a given separation kernel con figuration.
The tool is effective in proving the assumptions, leading to machine-checked proofs of
correctness for 16 different input con figurations, as well as in detecting issues like undeclared
sharing of memory components in some seeded faulty con figurations
