With the aid of some results from the theory of fields we show that such problems can not be solved by the use of only a nongraduated ruler and compass. We present the conchoid, cissoidd and quadratrix curves (also called trissectors) along with their equations. Finally, we present alternative solutions to the three classic problems and highlight how some of the curves previously presented can help such solutions. / Este trabalho é sobre os três problemas clássicos da Geometria Grega: a duplicação do cubo, a trissecção do ângulo e a quadratura do círculo. Com o auxílio de alguns resultados da teoria dos corpos mostramos que tais problemas não podem ser resolvidos com o uso apenas de régua não graduada e compasso. Apresentamos as curvas conchóide, cissóide e quadratriz (também chamada de trissectriz) junto com suas equações. Por fim, fazemos a exposição de soluções alternativas para os três problemas clássicos e destacamos como alguma das curvas apresentadas anteriormente pode auxiliar tais soluções.

A construção de edificações residenciais de interesse social tem alcançado destaque atualmente no Brasil, principalmente através de programas promovidos pela Caixa Econômica Federal, como o Programa de Arrendamento Familiar (PAR), no qual o processo construtivo em alvenaria modular é utilizado amplamente. Esse processo construtivo vem sendo estudado há vários anos, e novas tecnologias são incorporadas gradativamente, visando à otimização da produção e melhoria da qualidade. Entretanto, antigos e novos problemas ainda ocorrem. Este trabalho é parte do projeto de pesquisa para transferência de tecnologia de materiais ao desenvolvimento de novos produtos para a construção de habitação de interesse social (COMPOHIS), que iniciou em fevereiro de 2007. Tem por objetivo o estudo das manifestações patológicas típicas da região de interface esquadria/alvenaria e seu entorno, identificando suas causas, analisando-as e elaborando propostas de soluções para evitá-las. Na identificação e análise das manifestações patológicas foi adotado o método de análise sistemática por observação direta proposto por RICHTER (2007), o qual foi aplicado nos dados obtidos pelo grupo de pesquisa do projeto COMPOHIS, em empreendimentos do programa PAR; enquanto que na elaboração de propostas de soluções foi adotada uma metodologia projetual proposta por AZAMBUJA (2008). De forma geral, verificou-se que a incidência de manifestações patológicas nas faces externas foi aproximadamente 34,6% superior às faces internas. A região com a maior incidência de manifestações patológicas, nesse sistema construtivo, foi a de entorno às esquadrias, e a fissura (CDU = 0,14) foi o tipo de manifestação com a maior incidência, 45% superior à segunda manifestação patológica de maior incidência, a fissura isolada, seguida pela umidade generalizada e fissura mapeada (que não apresentaram diferença significativa). / The residential buildings’ construction of social interest has been reaching highlights nowadays in Brazil, mainly through programs promoted by Caixa Econômica Federal, as Programa de Arrendamento Familiar (PAR), in which the constructive process in modular masonry is thoroughly used. This constructive process has been studied for several years, and new technologies are being incorporated gradually, looking for the best utilization of the production and the quality improvement. However, old and new problems are still happening. This work is part of a research project - that has began in February, 2007 – which tries to find new material’s technologies and transfer them to the design of new products for the construction of social interest houses (COMPOHIS). It has for objective the study of the typical pathological manifestations between mitre/masonry and their around, identifying their causes, analyzing them and elaborating proposes of solutions to avoid them. In the identification and in the analysis of these pathological manifestations the method of systematic analysis by direct observation proposed by RICHTER (2007) was adopted. This method was applied in the data obtained by COMPOHIS research group, in PAR’s constructions. During the elaboration of solutions was adopted a project methodology proposed by AZAMBUJA (2008). In general, it was found that the incidence of pathological events in the external side was approximately 34,6% higher than the internal side. The area with the highest incidence of pathological events, in this constructive system, was the around frames area, and type of event with the highest incidence was the cleft (CDU = 0.14), which was 45% higher than the second highest incidence of pathological manifestations, the crack alone, followed by widespread humidity and cleft mapped (which didn’t present significant difference).

The concept of backward stochastic differential equation (BSDE) was initially brought up by Bismut when studying the stochastic optimal control problem. And it has been applied to describe various problems particularly to those in finance. After the fundamental work by Pardoux and Peng who proved the well-posedness of the nonlinear BSDE, the BSDE has been investigated intensively for both theoretical and practical purposes. In this thesis, we are concerned with a class of numerical methods for solving BSDEs, especially the one proposed by Zhao et al.. For this method, the convergence theory of the semi-discrete scheme (the scheme that discretizes the equation only in time) was already established, we shall further provide the analysis for the fully discrete scheme (the scheme that discretizes in both time and space). Moreover, using the BSDE as the adjoint equation, we shall construct the numerical method for solving the stochastic optimal control problem. We will discuss the situation when the control is deterministic as well as when the control is feedback.

The research question asks: “Is the policy for financial inclusion in Rwanda explicit, appropriate and effective?” The Government of Rwanda targets ‘financial inclusion’ for 80% of the population of Rwanda by 2017. The study considers what financial inclusion means, how policy has captured it, and whether policy implementation reaches the grassroots – and with what effect. Chapter 1 introduces the research study. Chapter 2 gives background to Rwanda’s development, the strategic policy cycle and planning processes, the accessibility of policy detail, and the aspiration for economic transformation to be a ‘middle income’ country by 2020. Professionalising public service, and the role of Rwanda’s leadership are considered, as are Rwanda’s demographic challenges. Chapter 3 reviews literature relevant to Rwanda’s development and to financial inclusion in development. It explores the ‘livelihoods’ analytic framework. Chapter 4 outlines methods and methodological approaches to this study. A ‘grounded theory’ approach is used and a mixed methods approach is applied to the data. The four data chapters (Chapters 5, 6 7, and 8) draw on voices of people involved in financial inclusion policy. In Chapter 5, villagers speak, via a household survey, about good things in their lives, challenges they face, and their actual livelihood activities. They explain their engagement with financial services, and discuss the role of asset ownership. In Chapter 6 senior policy makers speak of vision and pragmatism in financial inclusion policy, and their own rationale for supporting the policy. Chapter 7 focuses on voices at the mid-level of implementation: District level civil servants, cooperative managers, branch bank-managers. All describe challenges and achievements, explaining their personal route to this career position. Chapter 8 returns to grassroots, hearing voices of farmers (in groups and individually), using real lives to show impacts and limitations of the policy. Chapter 9 draws conclusions from the study: the impact of the policy for financial inclusion; the role of central and local leadership; the wider insights allowed into the nature of inclusive development; and the significance of Rwanda’s ‘Home Grown Solutions’. The study proposes a wider use of the livelihoods analytical framework as an aid to understanding transformation at diverse levels in development.

A resolução de problemas é uma estratégia didática/metodológica importante e fundamental para o desenvolvimento intelectual do aluno e para o ensino da matemática. Para muitos educadores matemáticos, a resolução de problemas consiste em permitir que os alunos utilizem seus conhecimentos e desenvolvam a capacidade de administrar as informações ao seu redor. Dessa forma, os alunos adquirem a oportunidade de ampliar seu conhecimento, desenvolver seu raciocínio lógico, enfrentar novas situações e conhecer as aplicações da matemática. O mesmo sucede para o professor, pois trabalhar com a resolução de problemas permite atingir os objetivos de aprendizagem definidos, além de tornar a aula mais interessante e motivadora. Neste trabalho particularizamos a utilização desta estratégia didática no ensino de funções, onde apresentamos a aplicação de uma atividade em sala de aula sobre esse conteúdo matemático. / This research aims to show the importance of the solving problem as a teaching strategy for mathematics education, with particular focus on functions. The solving problem is an important and fundamental didactic / methodological strategy for the intellectual development of the students and the teaching of mathematics. For many mathematics teachers the solving problem is allow the students to use their knowledge and develop the ability to deal with the information around than. So, the students gain the opportunity to expand their knowledge, develop their logical thinking, face new situations and learn about the applications of mathematics. The same applies to the teacher, because working with the problem solutions achieves the defined learning objectives, and make the class more interesting and motivating. In this research, we use this teaching strategy in teaching functions, where we present the application of an activity in class about this mathematical content.

As the engineering profession moves from prescriptive or “deemed-to-satisfy” approaches towards design methodologies based on quantification of performance, sophisticated modelling tools are increasingly needed, especially when complex combinations of demand and capacity are encountered. Recourse is invariably made to advanced computational tools to provide high fidelity solutions to large and complex problems, such as the response of structural systems or components to thermomechanical actions. Software packages based on the finite element method are most commonly used for such analyses. There are some essential prerequisites to effective use of advanced computational software for complex nonlinear problems, which are often ignored, particularly in professional practice. These include a thorough understanding of the underlying mechanics of the problem under consideration; a good appreciation of the approximation methods for modelling the problem properly (e.g. the choice between elements, continuum or structural, low or high order interpolation, degree of mesh refinement necessary and so on); and perhaps most importantly ensuring that the software is reliable and is able to reproduce established fundamental solutions to an acceptable degree of accuracy. This thesis attempts to address most of these issues but focusses primarily on the last mentioned prerequisite and provides a range of novel and unprecedented fundamental solutions for beams, plates, and shallow shells subject to moderate or extreme thermomechanical loads such as those resulting from a fire. Geometric and material nonlinearities are included in the proposed formulations along with the most common idealised boundary conditions. Thermally induced deformations generate large displacements and require the solutions to account for geometric nonlinearity, while material nonlinearity arises from the degradation of the material at elevated temperatures. In the context of structural performance under extreme thermal action (such as fire), a finite element procedure is employed to analytically characterise generic temperature distributions through the thickness of a structural component arising from different types of fire exposure conditions including: a “short hot” fire leading to a high compartment temperature over a relatively short duration; and a “long cool” fire with lower compartment temperatures, but over a longer duration. Results have shown that despite the larger area under the long cool fire time-temperature curve, which traditionally represented the fire severity, the effect of the short hot fire on the nonlinear responses of beams, plates, and shallow shells is more pronounced. Also, the effect of temperature-dependent material properties is found to be more pronounced during the short hot fire rather than the long cool fire. Comparison studies have confirmed that while the current numerical and theoretical approaches for analysing of thin plates and shells are often computationally intensive, the proposed approach offers an adequate level of accuracy with a rapid convergence rate for such structures. The solutions developed can be used to: verify software used for modelling structural response to thermomechanical actions; help students and professionals appreciate the fundamental mechanics better; provide relatively quick solutions for component level analyses; and visualise internal load paths and stress trajectories in complex structural components such as composite shells that can help engineers develop deeper insights into the relevant mechanics. The formulations developed are versatile and can be used for other applications such as laminated composite or orthotropic shallow shells. A very significant by-product of developing such fundamental solutions is their potential use in the development of highly accurate hybrid elements for very efficient modelling of large problems. While this has not been fully developed and implemented in the current work, the requisite theoretical framework has been developed and reported in one of the appendices, which can be used to develop such elements and implement on an appropriate software platform.
