Método híbrido para projeto de superfícies seletivas em frequência

This thesis presents a hybrid technique of frequency selective surfaces project (FSS) on a isotropic dielectric layer, considering various geometries for the elements of the unit cell. Specifically, the hybrid technique uses the equivalent circuit method in conjunction with genetic algorithm, aiming at the synthesis of structures with response single-band and dual-band. The equivalent circuit method allows you to model the structure by using an equivalent circuit and also obtaining circuits for different geometries. From the obtaining of the parameters of these circuits, you can get the transmission and reflection characteristics of patterned structures. For the optimization of patterned structures, according to the desired frequency response, Matlab™ optimization tool named optimtool proved to be easy to use, allowing you to explore important results on the optimization analysis. In this thesis, numeric and experimental results are presented for the different characteristics of the analyzed geometries. For this, it was determined a technique to obtain the parameter N, which is based on genetic algorithms and differential geometry, to obtain the algebraic rational models that determine values of N more accurate, facilitating new projects of FSS with these geometries. The optimal results of N are grouped according to the occupancy factor of the cell and the thickness of the dielectric, for modeling of the structures by means of rational algebraic equations. Furthermore, for the proposed hybrid model was developed a fitness function for the purpose of calculating the error occurred in the definitions of FSS bandwidths with transmission features single band and dual band. This thesis deals with the construction of prototypes of FSS with frequency settings and band widths obtained with the use of this function. The FSS were initially reviewed through simulations performed with the commercial software Ansoft Designer ™, followed by simulation with the equivalent circuit method for obtaining a value of N in order to converge the resonance frequency and the bandwidth of the FSS analyzed, then the results obtained were compared. The methodology applied is validated with the construction and measurement of prototypes with different geometries of the cells of the arrays of FSS.

Projeto de intervenção adaptando o Balanced Scorecard ao sistema de compras da Base Aérea de Natal

The present proposal for intervention examines the issue of public procurements carried out by a military organization on a Federal Public Administration. The main objective of this paper is to propose a model of strategic planning based on the Balanced Scorecard for the public procurement system, which contributes to increased efficiency, efficacy and effectiveness of acquisitions made in the Air Base of Natal city. Therefore, Structured interviews were used in order to make a diagnosis of the current reality of the procurement system along with the main requirement sectors of BANT, as well as the adaptation of the prospects of the BSC based on literature review. The technique used for the analysis of the interviews was the analysis of content whose results contributed to the preparation of the conceptual Strategic Map which was submitted to validation through a Focal Group. It was concluded through the analysis of the interviews, that the system of purchases of BANT is in a tactical profile because of low interaction between the system of purchases and the requirement sectors, aiming only at the “economicity” of acquisition in opposition of the effectiveness of material acquired, the lack of training of the elements which build the system and the absence of a proper planning. It is intended with thecreation of this proposal to contribute to the improvement of management with a focus on results in public administration as well as increasing efficiency, efficacy and effectiveness of public procurements. Whereas for the particular case the measurement of the results can only be performed after at least a year of its implementation, the present research constitutes a proposal of intervention.

Efeito do trabalho de projeto na abordagem da estatística nas atitudes face à matemática de alunos do 6.º ano de escolaridade

O presente trabalho constitui uma investigação levada a cabo no âmbito do Mestrado e Ensino do 1.º e 2.º Ciclos de Educação Básica. A problemática surgiu no decorrer da minha prática pedagógica no seio de uma turma do 6.º ano, numa Escola Básica do centro do país. Partindo da necessidade da tomada de posição perante o ensino e a sua finalidade, centra-se na perspetiva de que além da promoção de aquisição de informação, conteúdo e experiência Matemática, também é finalidade do ensino desta disciplina o desenvolvimento de atitudes positivas face à mesma e a capacidade de apreciar esta ciência. Pretende verificar o efeito de um trabalho de projeto nas atitudes dos alunos, pois conhecer apenas a atitude que apresentam em relação à matemática não previne que a mesma evolua no sentido negativo ao longo da escolaridade obrigatória. O projeto realizado na turma teve como dinâmica o trabalho de grupo, no qual os alunos desempenharam o papel de produtores e de consumidores de informação estatística. Avalia a atitude dos alunos em três momentos da concretização do projeto – antes, durante e depois; por forma a evidenciar semelhanças e diferenças nos três momentos, bem como o que poderá ter influenciado o resultado obtido. Considerando a atitude com base em três componentes principais – afetiva, cognitiva e comportamental, a análise dos dados traduziu-se na análise das expressões de comportamento verbal e não-verbal a partir da qual foi inferida a componente de atitude refletida. Os resultados obtidos apontam para uma melhoria nas atitudes dos alunos mediante a metodologia utilizada, nomeadamente no que respeita à apreciação desta ciência através da compreensão da sua aplicabilidade no quotidiano diário e futuro profissional, bem como ao autoconhecimento das suas competências em relação ao tema matemático abordado. Poderia ter tido uma influência mais positiva nas atitudes dos alunos, nomeadamente na componente comportamental, se estes já tivessem desenvolvido competências intrínsecas ao trabalho cooperativo.

O EU na Osteoartrose : comparação dos Core Sets da CIF para a Osteoartrose, com a perspetiva dos utentes com OA da região centro de Portugal

Introdução: Na prática diária, os clínicos necessitam apenas de uma fração das categorias encontradas na CIF. No conflito entre a generalização e a necessidade de captar detalhes, a CIF deve ser adaptada às perspetivas e necessidades de diferentes utilizadores. Esta necessidade surge como a principal motivação por detrás do projeto dos Core Sets, que tem como objetivo extrair uma seleção de categorias de toda a classificação que são relevantes para condições específicas de saúde. Após o desenvolvimento da primeira versão dos Core Sets da CIF para a OA, os autores realçaram a importância desta ser testada sob a perspetiva de diferentes profissionais, em diferentes países e ainda segundo a perspetiva dos indivíduos. Objetivos: Identificar os problemas percecionados pelos indivíduos com OA, da região centro de Portugal e verificar em que medida estes aspetos se encontram compreendidos no Comprehensive e Brief Core Set da CIF, para esta condição de saúde. Metodologia: Foi realizado um estudo qualitativo, recorrendo a uma amostra de conveniência, indivíduos com OA no joelho e/ou anca. A recolha de dados consistiu em entrevistas individuais, e o seu processamento foi efetuado segundo o protocolo de Coenen (2008). Resultados: Foram incluídos 20 indivíduos, perfazendo uma média de idades de 69,65 (±9,8) anos, dos quais 9 são mulheres e 11 homens. Foram identificadas 34 das 55 categorias contempladas no Comprehensive Core Set da CIF e 9 das 12 categorias do Brief Core Set da CIF, 61,82% e 75%, respetivamente. Conclusões: Tendo em conta os resultados, conclui-se que os Comprehensive e Brief Core Sets da CIF para a OA abrangem a perspetiva da população portuguesa, contudo não contemplam alguns dos problemas percecionados pelos indivíduos. Além disso, ainda se verifica que integra algumas categorias não relevantes para esta população.

Ribeira, técnica versus natureza: transformações em prol de um projeto de modernização (1860-1932)

The necessity of the insertion of the capital of Rio Grande do Norte in the world-wide commercial scene and its claim as the seat of political power, in ends of nineteenth and beginning of twentieth century, determined the direction of urban interventions undertaken by government to restructure the city. In that matter, there were several actions of improvements and embellishment in Natal, which had, as a starting point, the adequacy works of the port, located in the Ribeira quarter, with the aim of ending the physical isolation that reinforced its economic stagnation. Besides the problems faced in the opening bar of the Potengi River, and would complement the required improvements, other barriers demonstrate the tension established between the physic-geographic field and the man: the flooded and slope which connected Cidade Alta and Ribeira the first two quarters of the city.The execution of these works demanded knowledge whose domain and application it was for engineering. But, how the actions done for the engineers, in sense to transform natural areas into constructed spaces made possible the intentional conformation of the quarter of the Ribeira in a commercial and politician-administrative center, in the middle of the XIX century and beginning of the XX? Understand, therefore, the employment effects of technology on the physical-geographical Ribeira, is the objective of this work that uses theoretical and methodological procedures of Urban Environmental History, by analyzing the relationship between the environment and the man, mediated by knowledge and use of technologies. The documental research was used, as primary sources, the Messages of the Provincial Assembly Government that later became the Legislative Assembly of Rio Grande do Norte reports and articles on specialized publications, in addition to local newspapers. The work is structured in five chapters. First, some comments about Urban Environmental History (Chapter 1) supplemented with analysis of the conceptual construction of nature in the Contemporary Era and its application in the city (chapter 02), the following chapters (03 and 04) deal with the rise of engineers as a active group in the Brazilian government frameworks and their vision about the nature inside the urban environment and it is studied how the professional technicians dealt with the improvement work of the harbor and in the shock with the natural forces. Other works that would complement this "project" of modernization and had had natural obstacles to be removed the Ribeira flood and slope constitute the subject of the fifth chapter. Finally, some final considerations retake the initial discussions aiming an association between the technique and the nature as junction elements inside the process of constitution of a Modern Natal
