Der volle Inhalt der QuelleIn 1st part, variational formulations associated with resonant Maxwell equations are constructed. The equations degenerate in the domain, leading to the non-unicity and singularity of the solutions. Adding viscosity desingularizes the equations, and a limiting absorption process, when this viscosity parameter goes to zero, allows to identify the physical solution. The degeneracy separates the problem at the limit into two equations on different domains coupled by their interface, along which the solutions blow up. This work explicitly characterizes the limit solution as a solution of a well-posed formulation, which allows the numerical approximation of the physical solution to the resonant Maxwell equations. The study is motivated by the modeling of hybrid resonances in fusion plasma. A 2nd part concerns numerical domain decomposition methods (DDM). In the presence of corners and cross points, when using an automatic mesher for example, it is necessary to treat these points to obtain absorption (ABC) or transmission (TC) conditions of order higher than 1. We define ABCs of order 2 for the Helmholtz equation on a polygonal domain, with the further intention of deriving TCs treating cross points. Each algorithm presented is endowed with a decreasing energy and is convergent

Der volle Inhalt der QuelleIn this thesis, we are interested in the spectral properties of the Laplacian with the attractive Robin boundary condition on planar domains with corners. The aim is to understand the influence of the convex corners on the spectral properties of this operator when the Robin parameter is large. In particular, we show that the asymptotics of the first Robin eigenvalues on curvilinear polygons is determined by model operators: the Robin Laplacians acting on infinite sectors. For a particular class of polygons with straight edges, we prove the existence of an effective operator acting on the boundary of the domain and determining the asymptotics of the further eigenvalues. Finally, some Weyl-type asymptotics for different thresholds depending on the Robin parameter are obtained

Der volle Inhalt der QuelleThis thesis is devoted to the study and the mathematical justification of some models used in the numerical simulation of patch antenna. The reduction of dimension required for a correct description of the electromagnetic field lying between the patch and the metallic masse plan and the involvement of a boundary layer in the vicinity of the antenna edges makes difficult the direct numerical simulation of the electromagnetic field radiated or emitted by the antenna. A heuristic approach, called ”the cavity with magnetic walls model” is wide-spread in the engineering literature and used application for this type of simulation. In this work, we give a rigorous mathematical justification to this heuristic model using the matched asymptotic expansions method. Indeed, we show that in fact the heuristic model is a first order approximation of the true electromagnetic field emitted or radiated by the antenna. We also construct a higher-order model imporving the accuracy in the determination of the electromagnetic field. The construction of these models requires the handling of non standard boundary value problems which are thoroughly studied

Der volle Inhalt der QuelleAtravés da parceria entre o ISEG e a EMEL - Empresa Municipal de Mobilidade e Estacionamento de Lisboa, foi realizado um estágio profissional, tendo como objetivo otimizar as rotas dos operadores de coleta da EMEL. Foi assim definido o objetivo de identificar, de forma automática, rotas que permitam coletar mais dinheiro no fim de cada turno, reduzindo e homogeneizando os montantes de dinheiro que ficam na rua e, por consequência, o risco de roubo. O problema enquadrado no Vehicle Routing Problem with Profits, identifica rotas que, partindo e regressando de/a um ponto fixo (a base), visitam um certo conjunto de nodos (parquímetros), compatíveis com a capacidade do veículo e com a duração dos turnos dos operadores de coleta. Não se exige que todos os nodos sejam visitados diariamente, sendo apenas visitados os que garantem maior retorno. Foi construída uma função para estimar o valor depositado em cada parquímetro, por hora, sendo assim possível estimar o seu valor no momento da coleta. De seguida, desenvolveu-se e programou-se (em VBA) uma heurística construtiva para a geração de rotas.
Through the partnership between ISEG and EMEL - Empresa Municipal de Mobilidade e Estacionamento de Lisboa, the traineeship has been proposed aiming to optimize the routes made by the EMEL's coin collection operators. The scope is to automatically identify routes that allow the coin collection of more parking meters at the end of each working shift, reducing the amount of money left on the street. The problem was interpreted as a Vehicle Routing Problem with Profits. The routes start and end at a fixed point (the base), and the vehicles must visit a certain set of nodes (metered), within the crew time limit. In this problem there is no need to visit every node daily but to visit those that guarantee a higher return, provided that both the vehicles' capacity and the time limits are satisfied. A valuation function was built to estimate the value deposited in each parking meter per hour. Then, a constructive heuristic was developed and programmed (VBA) to generate routes.

The counterfeit coin problem is a well-known problem. There are some people who have tried to make the problem more challenging by adding more constraints on the problem. There are also a lot of people presenting different algorithms for variants of the problem. In this paper, we will propose some algorithms and strategies to solve some sort of the counterfeit coin problems, including the 2-counterfeit coins problem with unknown weight, and the k-counterfeit coins with known weight, where k 3. In addition, we will provide the analysis of the algorithms for these counterfeit coins problems. According to the analysis, we will know the theoretical lower bound of the numbers of the weighting when we are looking for the counterfeit coins in a mass of coins. Thus, we will know which strategy of the problem might be further improved.

There are also a lot of researchers presenting different algorithms for variants of the problem. In this paper, we propose some improved algorithms and strategies to solve some kinds of the counterfeit coin problems, including the 2-cointerfeit coins problem with unknown weight、the 3-cointerfeit coins problem with known weight、the 3-cointerfeit coins problem with unknown weight、the 4-cointerfeit coins problem with known weight、the 4-cointerfeit coins problem with unknown weight. We also tackle the k-counterfeit coins problem with unknown weight by improving the algorithm proposed by Li-Jhong Li, in which he only dealed with the k-counterfeit coins problem with known weight, . In addition, we provide the analyses of the algorithms for these counterfeit coins problems. According to the analyses, we will know the theoretical lower bound of the numbers of weightings to identify the counterfeit coins in a mass of coins. Thus, we will know which strategy of the problem might be further improved.

Coin Problem is known as Money-Changing Problem, Coin Exchange Problem, or Stamp Exchange Problem. It is a very famous problem. Now it already has solution for two variables. It has been proven that there is no closed-form solution for more than three variables. But it is already known that there are upper bounds in some situations. In this thesis, we focus on solving the coin problem for three variables. We discover a table-filling approach which can be used to deduce the regularities of Frobenius numbers. From it, we derive a fast way to find answers in some special cases, i.e. the smallest vaule among the three variables is either 2, 3, 4, 5 or 6. It can find answers directly from the formulas which are very easy to be calculated.

The coin problem is known as the money-changing problem, the coin exchange problem, or the stamp exchange problem, which is an old and famous problem. The coin problem is to ask for the largest integer that cannot be made up from the given integers. Now it already has solutions for two variables and has been proven that there is no closed-form solution for more than three variables. For three variables, there are upper bounds or certain formulas in some situations. This thesis extends the result of “Research on the Coin Problem for Three Variables”. We build a program that can guess the linear formulas of the coin problem for three variables, with its smallest value up to 16. Also, we prove the guessing of the linear formulas is correct when the smallest value is 7. Furthermore, we deduced some properties for automated theorem proving and built a program that can partly prove the linear formulas. With these results, we may solve the coin problem for three variables in the future.
