1. Métodos com passo temporal adaptativo para a simulação de escoamentos com superfícies livres / Adaptative time-step methods for the simulation of free surface flows
The simulation of free surfaces flows has gained importance in the recent years due to the many practical applications of this type of flow. Among the many numerical methods available for the simulation of fluid flows, there is GENSMAC, which is a numerical technique to simulate Newtonian flows with free surfaces. The implementation of semi-implicitmethods f

2. Image transformations based on mathematical morphology operations / Transformações de imagens baseadas em morfologia matematica
In this work, we present a new set of image transformations that can be used as an additional step in several applications, such as segmentation, to avoid the need of operations with a higher computational cost. These transformations are based on mathematical morphology operations and have the format of a toggle operator. The first proposed operation has sca

3. Geração genética de classificador fuzzy intervalar do tipo-2
The objective of this work is to study, expand and evaluate the use of interval type-2 fuzzy sets in the knowledge representation for fuzzy inference systems, specifically for fuzzy classifiers, as well as its automatic generation form data sets, by means of genetic algorithms. This work investigates the use of such sets focussing the issue of balance betwee

4. Resistência fisiológica e comportamental de populações de Sitophilus zeamais à permetrina, esfenvalerato e esfenvalerato + fenitrotiona / Physiological and behavioral resistance of populations of Sitophilus zeamais to permethrin, esfenvalerate and esfenvalerate + fenitrothion
The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) is considered the main pest of stored maize in Brazil and its control is achieved mainly by insecticides. The massive and intensive use of these compounds may lead to selection of resistant populations and consequently compromise the control efficacy of this insect pest in Bra

5. Algoritmo genético-tabu para a programação reativa da produção em um sistema de manufatura com recursos compartilhados
Manufacturing systems with shared resources have been designed to meet the market needs, which require high quality products, low cost and the guarantee of the conditions agreed with the customer. The production scheduling in a manufacturing system is a complex task due to its combinatorial nature. Several studies show the use of search methods, such as Gene

6. Resistência a fosfina: magnitude, mecanismo e custo adaptativo / Phosphine resistance: magnitude, mechanism and adaptative cost
The resistance of the insect-pests to fumigants has been frequently reported in stored grains and a present is one of the great obstacles to the control programs involving the use of chemical pesticides. This study was therefore carried out to detect phosphine resistance in populations of Tribolium castaneum, Rhyzopertha dominica and Oryzaephilus surinamensi

7. Scatter search for Heterogeneous Fleet vehicle routing problem with Time Windows and Split Deliveries. / Scatter Search para problemas de roterização de veículos com frota heterogênea, janelas de tempo e entregas fracionadas.
This thesis studies the implementation of heuristics and scatter search (SS) metaheuristic in a Heterogeneous Fleet Vehicle Routing Problem with Time Windows and Split Deliveries (HFVRPTWSD). The HFVRPTWSD is a combination of Heterogeneous Fleet Vehicle Routing Problem (HFVRP), Vehicle Routing Problem with Time Windows (VRPTW) and Vehicle Routing Problem wit

8. Evaluation of the quality of wooden plates through a fuzzy inference system based in adaptative networks. / Avaliação da qualidade de placas de madeira através de um sistema de interferência nebuloso baseado em redes adaptativas.
Automatic visual inspection is an important task for industrial productivity. It could be applied for quality control or for replacing manual work under dangerous or repetitive activity. The classification stage in quality control of the industrial production is often based on the human knowledge. It seems, therefore, to be a great concern to supply an autom
