13. Problemas industriais de seqüenciamento de padrões: alguns resultados de complexidade e novos modelos de busca local / Industrial pattern seguencing problems: some complexity results and new local search models
In this thesis we explore some industrial pattern sequencing problems arising in settings as distinct as the scheduling of flexible machines, the design of VLSI circuits, and the sequencing of cutting patterns. This latter setting presents us the minimization of open stacks problem, which is the main focus of our study. Some complexity results are presented

14. Industrial pattern seguencing problems: some complexity results and new local search models / Problemas industriais de seqüenciamento de padrões: alguns resultados de complexidade e novos modelos de busca local
Nesta tese nós exploramos alguns problemas industriais originários de tarefas tão distintas quanto a programação de uma máquina flexível, o projeto de circuitos integrados VLSI e o sequenciamento de padrões de corte. Desta última tarefa provêm o problema de minimização de pilhas em aberto que é o principal foco do estudo. Alguns resultados de co

15. Fluxo de potencia otimo parametrico
The aim of this work is to present a parametric method for the resolution of the Optimal Power Flow (OPF) problem applied to large scale power systems. This research work on parametric optimization applied to OPF was developed at UNICAMP and at McGiII University, in Montreal, Canada. The parametric approach consists of relaxing the original problem (OPF) by

16. Modelagem matematica, controle e otimização do processo de incineração em formos rotativos com pos-combustor
The development of a suitable mathematical model, in steady state and dynamic conditions , to carry out optimization and control of the large scale incineration process, stimulated the approach proposed in this work. The development of the mass and energy balances, as well as all the flows of heat, conductive, convective and radiative, were idealized to have

17. Metodos de solução do fluxo de potencia otimo reativo e tratamento das restrições de desigualdade
The Reactive Optimal Power Flow (ROPF) is a computational optimization tool that dispatches all reactive power sources of an electrical power system. It is extremely important in power system planning, operation and voltage collapse simulation. Its mathematical modeling involves nonlinear nonconvex equality constraints and linear and nonlinear nonconvex ineq

18. Defining and identifying communities in networks
The investigation of community structures in networks is an important issue in many domains and disciplines. This problem is relevant for social tasks (objective analysis of relationships on the web), biological inquiries (functional studies in metabolic and protein networks), or technological problems (optimization of large infrastructures). Several types o

19. Efficient Improvement of Silage Additives by Using Genetic Algorithms
The enormous variety of substances which may be added to forage in order to manipulate and improve the ensilage process presents an empirical, combinatorial optimization problem of great complexity. To investigate the utility of genetic algorithms for designing effective silage additive combinations, a series of small-scale proof of principle silage experime
