Texto completoEste trabalho apresenta uma abordagem pelo método dos elementos finitos para o cálculo da resposta tridimensional, estática e dinâmica, de estruturas unidimensionais total ou parcialmente imersas em um fluido em movimento. A técnica utilizada baseia-se na separação do movimento de corpo rígido dos deslocamentos totais do elemento resultando naqueles que efetivamente causam deformações, consideradas infinitesimais, sob condições de rotações finitas. A posição da estrutura é definida por um conjunto de eixos co-rotacionados e a avaliação das rotações deste sistema é detalhada. O estudo apresentado considera as não-linearidades decorrentes da mudança de geometria, do acoplamento entre os mecanismos de rigidez axial e transversal e do carregamento hidrodinâmico, considerado proporcional ao quadrado da velocidade relativa entre fluido e estrutura. Na discretização espacial das equações de equilíbrio, a hipótese de pequenas deformações é empregada. Desta forma, a utilização do sistema de coordenada co-rotacionado permite considerar-se um elemento de dois nós baseado no modelo de viga de Euler-Bernoulli com funções de interpolação dos deslocamentos nodais utilizando os polinômios cúbicos de Hermite e referidos ao sistema convectivo de cada elemento. Na integração temporal das equações de equilíbrio, utiliza-se o procedimento passo-a-passo de Newmark juntamente com a técnica iterativa de Newton-Raphson, obtendo-se, a cada instante de tempo, a configuração correspondente ao equilíbrio dinâmico da estrutura discretizada. O procedimento apresentado foi implementado em um programa de computador tendo-se verificado, para diversos exemplos, uma convergência satisfatória entre os resultados do modelo implementado e aqueles obtidos de outros com origem independente.
This work presents a finite element approach to the three-dimensional static and dynamic response calculations of slender structures totally or partially immersed in a moving fluid. The technique is based on the separation of rigid body motions from the element total displacements resulting in those that effectively cause strain, and which are assumed infinitesimal, under conditions of finite rotations. The position of the structure is defined by a set of co-rotational axes and the evaluation of the finite rotations of this system is detailed. The study considers the non-linearities due to change in geometry, coupling between the axial and bending stiffness mechanisms and the velocity-squared drag loading. For the spatial discretization of the equilibrium equations, the small strain hypothesis is employed. The use of the co-rotational coordinate system makes possible to consider a two node element based on the Euler-Bernoulli beam kinematic model, with cubic Hermitian interpolation functions for the nodal displacements obtained at the convective coordinate system of each element. The Newmark step-by-step scheme is applied to directly integrate, in the time domain, the equilibrium equations and the Newton-Raphson iterative algorithm employed t solve the resultinh incremental non-linear set of equations, at each time step. The presented procedure was implemented in a computer program and various example results were satisfactorily tested against the ones obtained from independent programs.

A combinação de Linhas de Produto de Software (LPS) e Computação Orientada a Serviços (COS) tem recebido atenção de pesquisadores e praticantes, já que uma área é capaz de solucionar determinados problemas da outra. A junção dessas duas áreas é chamada de Linha de Produto Orientada a Serviços (LPOS), e tem se mostrado uma área de pesquisa emergente nos últimos anos. No contexto da Computação Orientada a Serviços, identificação de serviços é uma das primeiras atividades para modelagem de uma solução COS, e consiste na determinação de serviços candidatos. Essa não é uma tarefa trivial, e os erros adquiridos durante a identificação de um serviço pode propagar-se para as atividades subsequentes do processo de desenvolvimento orientado a serviços. Existem diversas propostas para identificação de serviços. Apesar da diversidade, não existe um método de identificação de serviços capaz de adequar-se a diversos contextos e necessidades. Considerando a heterogeneidade desses métodos, esta dissertação tem o objetivo de verificar quais métodos podem ser aplicados em linhas de produto de software, bem como as vantagens, desvantages e desafios existentes neste campo. Esta pesquisa utilizou uma abordagem multi-métodos, que combina estudos primários e secundários a fim de incrementar o corpo de conhecimento em determinada área baseada nos achados de tal investigação. Desta forma, este trabalho utilizou um método secundário (revisão sistemática) e dois métodos primários com o intuito de aumentar a confiabilidade dessa pesquisa. Além disso, foi realizada uma revisão da literatura a fim de coletar as abordagens de identificação de serviços existentes, visando propor uma recomendação dos métodos mais adequados considerando três cenários de LPS: top-down, bottom-up e hybrid. Esta recomendação foi avaliada através de um estudo de caso com uma linha de produto de sistemas médicos, usando dois metodos classificados no cenário o qual os sistemas médicos encontram-se, top-down. A principal contribuição dessa pesquisa é prover um instrumento que auxilie os interessados em identificar serviços a escolher um método apropriado, levando em consideração o cenário SPL a ser aplicado. Os resultados do estudo de caso mostram que as abordagens de identificação de serviços podem ser aplicadas num contexto de LPS. Além disso, este métodos facilitam a realização da atividade de identificação.
The combination of Software Product Line (SPL) and Service-Oriented Computing (SOC) have started to receive attention by researchers and practitioners, since they can address issues of each other. Putting these two areas together is called Service-Oriented Product Lines Enginering (SOPLE), presenting itself as an emerging area in the last years. In the Service-Oriented Computing, service identification is one of the first activities in the modeling of a SOC solution, that consists of determining candidate services. This is not a trivial task, and the errors made during the identification can propagate mistakes to the next activities of the service-oriented development process. There are several proposals addressing service identification for several contexts. However, an unified method for identifying services has not yet been reached. Regarding the heterogeneity of these methods, this dissertation aims to verify which methods can be applied in the SPL context, the advantages, disadvantages and the existing challenges of this field. This research used a multi-method approach that combines primary and secondary studies in order to increase the availability of empirical knowledge based on the findings of the investigation. Thus, this work used one secondary method (systematic review) and two primary methods (survey and case study) to address it. Furthermore, it was performed a literature review in order to collect all existing approaches of service identification, aiming to propose a set of decision models that recommend the most suitable methods according to three SPL scenarios: bottom-up, topdown and hybrid, onde decision model for each scenario. One of the decision models was evaluated through a case study in a medical applications domain, using two approaches classified in the decision model of the top-down scenario. The main contribution of this research is to provide an instrument that can help the service identification stakeholders to choose a suitable method, taking consideration of their SPL scenarios. In addition, these systematic methods facilitate the application of the identification activity. The case study results evaluated some service identification approaches and presented evidence that the methods can be applied in SPL.

Texto completoMany chemical and physical problems are mathematically described by partial differential equations (PDEs). These PDEs are often highly nonlinear and therefore have no closed form solutions. Thus, it is necessary to recourse to numerical approaches to determine suitable approximations to the solution of such equations. For solutions possessing sharp spatial transitions (such as boundary or interior layers), standard numerical methods have shown limitations as they fail to capture large gradients. The method of lines (MOL) is one of the numerical methods used to solve PDEs. It proceeds by the discretization of all but one dimension leading to systems of ordinary di erential equations. In the case of time-dependent PDEs, the MOL consists of discretizing the spatial derivatives only leaving the time variable continuous. The process results in a system to which a numerical method for initial value problems can be applied. In this project we consider various types of singularly perturbed time-dependent PDEs. For each type, using the MOL, the spatial dimensions will be discretized in many different ways following fitted numerical approaches. Each discretisation will be analysed for stability and convergence. Extensive experiments will be conducted to confirm the analyses.

Texto completoIn this work, the Method of Lines applied to the study of the propagation caracteristics of planar structures is presented. In this method, the spacial variables are discretized in several lines orientated in a direction normal to the conductor strips. Then, the partial differential equations are reduced to ordinary differential equations having well known solutions. Although this method uses finite differences, it is much more efficient with respect to computer speed and memory necessary, in comparison to the conventional finite difference method. A few planar structures with three dieletric layers, inside rectangular waveguides were analysed, and the results are compared with those using other reported methods. In the appendix, it is shown how to develop computer programs using non-uniform discretization for the improvement of the efficiency of this method. Also, the discretization in two directions is presented, which is adequate for analysis of microwave resonators. This work is intended as a basic approach to hel in further analysis using the Method of Lines.

Texto completoElectromagnetic coupling phenomena between overhead power transmission lines and other nearby structures are inevitable, especially in densely populated areas. The undesired effects resulting from this proximity are manifold and range from the establishment of hazardous potentials to the outbreak of alternate current corrosion phenomena. The study of this class of problems is necessary for ensuring security in the vicinities of the interaction zone and also to preserve the integrity of the equipment and of the devices there present. However, the complete modeling of this type of application requires the three- -dimensional representation of the region of interest and needs specific numerical methods for field computation. In this work, the modeling of problems arising from the flow of electrical currents in the ground (the so-called conductive coupling) will be addressed with the finite element method. Those resulting from the time variation of the electromagnetic fields (the so-called inductive coupling) will be considered as well, and they will be treated with the generalized PEEC (Partial Element Equivalent Circuit) method. More specifically, a special boundary condition on the electric potential is proposed for truncating the computational domain in the finite element analysis of conductive coupling problems, and a complete PEEC formulation for modeling inductive coupling problems is presented. Test configurations of increasing complexities are considered for validating the foregoing approaches. These works aim to provide a contribution to the modeling of this class of problems, which tend to become common with the expansion of power grids.

s functions are in general Sommerfeld-type integrals which are computationally expensive. To improve the efficiency of the technique, Green&rsquo
s functions are approximated by their closed-forms. Microstrip lines are excited by arbitrarily located current sources and are terminated by complex loads at both ends. Current distributions over microstrip lines are represented by rooftop basis functions. At first step, the current distribution over a single microstrip line is calculated. Next, the calculation of the current distributions over coupled microstrip lines is performed. The technique is then, applied to directional couplers. Using the current distributions obtained by the analysis, the scattering parameters of the structures are evaluated by using Prony&rsquo

A abordagem de Linhas de Produtos de Software (SPL) pode ser considerada uma estratégia eficiente para o reuso de software. SPL oferece significativos benefícios econômicos para as empresas, tais como redução de custos, melhoria da qualidade, e redução do tempo de entrega de produtos. SPL baseia-se no reuso sistemático de artefatos, através da exploração de commonalities (pontos em comum), e o gerenciamento de variabilities (pontos de variação) entre os produtos, desenvolvidos sob uma arquitetura comum. No entanto, a percepção das vantagens de SPL tem um custo associado. Elas demandam maturidade nas técnicas de engenharia de software, planejamento e gerenciamento de reuso, adequadas práticas para gerenciamento e desenvolvimento, sendo capaz de lidar com questões organizacionais e de complexidade arquitetural. Na prática, não é relativamente fácil adotar a abordagem de linha de produto. No contexto de pequenas e medias empresas (SMEs), as dificuldades para adoção de linha de produto são ainda maiores, devido a baixa maturidade organizacional e falta de recursos comum a este tipo de organização. Neste contexto, esta dissertação apresenta um conjunto de evidências empíricas sobre a adoção de linhas de produto em pequenas e médias empresas. O conjunto de evidências contribui para o entendimento da adoção de linha de produto em SMEs por documentar barreiras, as melhores práticas existentes, experiências etc., facilitando a adoção da abordagem de SPL no futuro. Esta dissertação apresenta ainda uma abordagem multi-método para pesquisa empírica em engenharia de software, conduzida através da triangulação, combinando diferentes, mas complementares métodos de pesquisa, aumentando desta maneira a disponibilidade de conhecimento empírico na área.

Texto completoWe began the thesis by survey literature on SPLE and CbyC approaches in the State of the Art. Based on the overview and the insights obtained, we have analyzed the existing problems and suggested ways to solve them for our main goal. We have proposed in Chapter 2 a methodology to develop product lines such that the generated products are correct-by-construction. Our main intention is that a user does not need to know the product generation process but can receive a correct final product from selecting a configuration of features. Using the methodology, the final products are generated automatically and their correctness is guaranteed. Following this proposal, we have moved in Chapter 3 to define the FFML language that is used for writing modules. The reuse and modification mechanism, defined for the language and applied to all kinds of artifacts (specification, code and correctness proof), reduce the programming effort. In Chapter 4, we have focused on defining the composition mechanisms for composing FFML modules and embedded them into the FFML Product Generator tool. The evaluation of our methodology is performed through the development of two software product lines, the Bank Account SPL and the Poker SPL, the latter being a bit more complex than the former. In the evaluation, we have highlighted the advantages and the limitation of our methodology

Texto completoThe core study of this PhD thesis is the sloshing in satellite tanks, during low acceleration maneuvers. Indeed the helium bubble used to pressurize the tank moves, thus generating perturbations on the global stability of the satellite. In order to understand this problem, numerical schemes have been developed, such as an immersed boundary method to model the tank wall. The numerical tool uses a Level-Set function coupled to a Ghost Fluid Method to track the interface and to account for the jump conditions.A BlackBox Multigrid Solver have been developed to improve computational cost. Finally a study is presented in the last chapter to predict the behaviour of the fluids with a varying rotational speed generated during some classical maneuvers

O estudo de equações diferenciais parciais tem merecido muito destaque nos últimos anos.

Texto completowere benchmarked against experimental data and numerical solutions available in the literature and the capability of the code to predict transient solutions was demonstrated on these test cases. Favorable agreements were obtained for both test cases. The effect of radiation and non-gray treatment of the radiative properties were investigated on the second test case. It was found that incorporation of radiation has significant effect on Temeprature and velocity fields but its effect is limited in species predictions. Executions with both radiation models revealed that the non-gray radiation model considered in the present study produces similar results with the gray model at a considerably higher computational cost. The algorithm developed was found to be an efficient and versatile tool for the timedependent simulation of different flow scenarios constitutes the initial steps towards the computation of transient turbulent combustion.
