1. Estudo de alguns metodos determinsticos de otimização irrestrita / Study of some deterministic methods for unconstrained optimization
In this work some classical methods of linear search for unconstrained optimization are studied. The main mathematical formulations for the optimization problem are presented. Two strategies, linear search and trust region, for the algorithm to move from one iteration to another are discussed. Furthermore, the main considerations about the choice of step len

2. Um novo método híbrido aplicado à solução de sistemas não-lineares com raízes múltiplas / A new hybrid method applied to the solution of nonlinear systems with multiple roots
This paper aims to present solutions for nonlinear systems with multiple roots, using a hybrid algorithm. For this purpose was developed and implemented an algorithm based on random search method proposed by Luus and Jaakola (1973) as a step in search of random starting points, which will be refined through the algorithm of Hooke and Jeeves. The differential

3. Linearização Adaptativa por Alimentação Direta de Amplificadores de Potência Empregando FPGA / Linearização Adaptativa por Alimentação Direta de Amplificadores de Potência Empregando FPGA
Esta dissertação apresenta a implementação em hardware do tipo FPGA de um linearizador por alimentação direta para um sinal composto por dois tons senoidais na freqüência de 7 MHz. Os blocos necessários foram desenvolvidos dentro do programa Simulink, empregando os blocos do System Generator da empresa Xilinx. O programa de otimização implementado

4. MODELAGEM E OTIMIZAÇÃO EM ANTIBIOTICOTERAPIA / MODELING AND APTIMIZATION IN ANTIBIOTITHERAPY
Antibiotics are highly selective drugs with a great power against micro organisms. They´re quite efficient medicine and usualy do not cause relevant side effects. These drugs can be sometimes considered to act as biological filters selecting resistant populations, and consenquently causing drug innefficiency. Investigatios searching for less empirical appro
