3. Técnicas computacionais para a implementação eficiente e estável de métodos tipo simplex / Computational techniques for an efficient and stable implemantation of simplex-type methods
Simplex-type methods are the basis of the main linear optimization solvers. The straightforward implementation of these methods as they are presented in theory yield unexpected results in solving reallife large-scale problems. Hence, it is essencial to use suitable computational techniques for an efficient and stable implementation. In this thesis, we addres

4. COLD-ROLLING PROCESS OPTIMIZATION BY MEANS EXPERIMENT PLANNING / OTIMIZAÇÃO DO PROCESSO DE LAMINAÇÃO A FRIO ATRAVÉS DE PLANEJAMENTOS DE EXPERIMENTOS
This dissertation aims to develop a model by using experiment planning techniques applied to cold-rolling process to manufacture special steels utilized in the carbonated beverage market segment. The process consists of downgauging hot-rolled coil, which is further pickled for oxide removal, into a coil with the final thickness required by customer. It invol

5. Caracterização de reservatorios com tecnicas de otimização combinatorial
Stochastic modeling has received increasing attention in the oil industry, being established as a ordinary tool for helping the elaboration of development plans in producing reservoirs. Combinatorial optimization techniques, such as simulated annealing, allow to produce equiprobable models of reservoir variables, reproducing a priori any characteristic that

6. A STUDY ON SLOTLINES AND APPLICATIONS / UM ESTUDO SOBRE SLOTLINES E SUAS APLICAÇÕES
This work presents the slotline as an alternative MIC`s transmission line. Special emphasis was given to the slotline design and to the effect of tolerances in various parameters on the performance of the slotline, using sensitivity analysis. The first chapter discusses some previously reported methods of analysis, using a compative approach. The second chap
