1. Multiplicidade de Soluções para Problemas Elípticos Semilineares Envolvendo o Expoente Crítico de Sobolev
In this dissertation, we study the multiplicity of solutions for the following class of semilinear elliptic problems involving the critical Sobolev exponent, u = juj22 u + f (x; u) ; x 2 e u = 0; x 2 @ ; where N 3, RN is a smooth and bounded domain, is a positive real parameter and 2 = 2N= (N - 2) is the critical Sobolev expon

2. Métodos variacionais aplicados a uma classe de equações de Schrödinger quasilineares
Neste trabalho, estabelecemos a existência de uma solução positiva, em RN, para uma classe de equações de Schrödinger quasilineares com não linearidade subcrítica ou crítica. A fim de utilizarmos Métodos Variacionais, aplicamos uma mudança de variável para reduzirmos as equações quasilineares a equações semilineares, cujos funcionais associad

3. Non-parametric regression with correlated errors using wavelets / Regressão não-paramétrica com erros correlacionados via ondaletas.
In this thesis, rates of convergence to zero are obtained for the estimation risk, for non-parametric regression using wavelets, when the errors are correlated. Four non-parametric regression methods using wavelets, with un-equally spaced design are studied in the presence of correlated errors, that come from stochastic processes. Conditions on the errors an

4. Study of a class of quasilinear Schrodinger equation / Estudo de uma classe de equações de Schrodinger quase-lineares
In this work, we study questions related to existence, multiplicity and concentration behavior of standing waves, for a class of quasilinear Schrödinger equations, arising, for example, in Plasma Physics. To obtain our results, we use variational methods, such as, minimax theorems and also regularity theory of elliptic equations of second order

5. Aproximação de nuvens de pontos de dados por meio de superfícies de Bézier
The computational and empirical modelling of geophysical phenomena, such as F region zonal plasma drifts, is a basic tool for the understanding and forecasting of effects that have great social-economic impact on the human activities. This work proposes, develops and implements a model, based on Computer Aided Geometric Design techniques, to F region zonal p

7. APLICAÇÃO DE MÉTODOS DE OTIMIZAÇÃO DETERMINÍSTICOS AO PROJETO ESTATÍSTICO DE CIRCUITOS / APPLICATION OF DETERMINISTIC OPTIMIZATION METHODS IN THE DESIGN OF STATISTICAL CIRCUITS
The increase of the electronic circuits complexity motivated the use of computer supported design techniques. These techniques, mainly based on the optimization methods, aids the designers to solve different problems related to the Electronic Circuit Design area. The large scale production of circuits, contrasting with the development of prototypes, creates
