13. Fuzzy logic applied to the modeling of the transfer of water in soils / LÃgica fuzzy aplicada à modelagem da transferÃncia de Ãgua em solos
Modeling water movement in the unsaturated soil requires a great number of parameters and variables such as the initial soil-water content, the saturated soil-water content, and the saturated hydraulic conductivity, which can relatively easily be assessed. Other functions such as hydraulic conductivity and matric potential which are nonlinear functions of th

14. Ant-Based Phylogenetic Reconstruction (ABPR): A new distance algorithm for phylogenetic estimation based on ant colony optimization
We propose a new distance algorithm for phylogenetic estimation based on Ant Colony Optimization (ACO), named Ant-Based Phylogenetic Reconstruction (ABPR). ABPR joins two taxa iteratively based on evolutionary distance among sequences, while also accounting for the quality of the phylogenetic tree built according to the total length of the tree. Similar to o

15. Aplications of genetic and fuzzy metaheusistic in the ant colony system for the traveling salesman problem / Aplicações de meta-heuristica genetica e fuzzy no sistema de colonia de formigas para o problema do caixeiro viajante
Amongst the several existing heuristical and accurate techniques for the resolution of combinatorial problems, the population algorithms ant colony optimization and genetic have been detached due to their good performance. In special the ant colony algorithms are considered currently as one of the techniques most succeeded for the resolution of some combinat

16. Otimização da topologia de circuitos de distribuição de energia elétrica usando algoritmos inspirados no comportamento de formigas
Colônias de formigas podem ser consideradas um sistema multi-agente, em que cada agente (formiga) opera independentemente por regras simples. Algoritmos baseados no comportamento de colônias de formigas têm sido usados para resolver problemas de otimização, pois, na procura por alimento, as formigas tendem a estabelecer a rota mais curta (ótima) entre

17. ModÃlisation et Optimisation robuste de systÃmes mÃcaniques en prÃsence dâamortissement viscoÃlastique / Modelagem e otimizaÃÃo robusta de sistemas mecÃnicos em presenÃa de amortecimento viscoelÃstico
Nos Ãltimos anos, os materiais viscoelÃsticos tÃm sido amplamente utilizados para reduzir os nÃveis de vibraÃÃo e de ruÃdo no domÃno da dinÃmica de estruturas, em virtude de sua capacidade inerente de absorver uma parte da energia vibratÃria dos sistemas mecÃnicos e de dissipÃ-la sob a forma de calor. Esses materiais sÃo aplicados com freqÃÃnc

19. UMA APLICAÇÃO DE ALGORITMOS DE COLÔNIAS DE FORMIGAS EM PROBLEMAS DE ROTEIRIZAÇÃO DE VEÍCULOS COM JANELAS DE TEMPO / AN APPLICATION OF ANT COLONY ALGORITHMS TO VEHICLE ROUTING PROBLEMS WITH TIME WINDOWS
Many advances in science were achieved from the observation of nature. Thousands of years of natural selection and evolution made certain living beings develop notable abilities and characteristics, that still nowadays surprise us with their complexity and adaptability. Some fields of science make constant use of intensive observation of these characteristic

22. Implementação de Equalizadores Allpass para Correção de Atraso de Grupo Empregando Técnicas de Otimização
Esta dissertação apresenta o desenvolvimento de um algoritmo, que utiliza métodos de otimização com o objetivo de obter filtros passa-tudo (allpass) estáveis para atuarem como equalizadores de atraso de grupo. O algoritmo obtém os coeficientes do filtro allpass a partir de uma resposta de atraso de grupo pré-definida. O projeto deste algoritmo envolv
