1. Condução de Experimentos Computacionais com Métodos Heurísticos / Conduction of Computational Experiments whit Heuristic Methods
The necessity of solving optimization problems in a reasonable computational time limit makes the development of heuristics be a large research area. Usually, developed heuristics for optimization problems are empirically evaluated by its application to a set of specific instances, comparing to quality solution and computational efforts. Besides, when presen

2. Condução de Experimentos Computacionais com Métodos Heurísticos / Conduction of Computational Experiments whit Heuristic Methods
A necessidade de resolver problemas de otimização em um limite razoável de tempo computacional faz com que o desenvolvimento de heurísticas seja uma grande área de pesquisa. Usualmente, heurísticas desenvolvidas para problemas de otimização são avaliadas empiricamente, pela sua aplicação a um conjunto de instâncias específicas, comparando qualid

3. Análise de sensibilidade topológica em modelos constitutivos multi-escalas / Topological Sensitivity Analysis in Constitutive Multi-Scale Models
The purpose of the present work is to carry out a topological sensitivity analysis in constitutive multi-scale models. By making use of the Hill-Mandel Principle of Macro-Homogeneity and the concept of volume average, a variational formulation was established to derive a clearly structured axiomatic framework for constitutive multi-scale models of the presen

4. Mathematical Modeling and Numeriacal Methods for Simulation of the Heat Conduction in Liquid Helium / Modelagem Matemática e Métodos Numéricos para Simulação da Condução do Calor no Hélio Líquido
The element helium, found mainly in natural gas reserves, condenses at temperature of 4.2K, and is the unique known substance that remains in liquid to absolute zero. In the liquid phase, the helium presents still another phase change in 2.19K, where passes of common liquid to superfluous liquid, with almost zero viscosity. These properties give the helium i

5. ExpVVT: uma ferramenta de apoio à condução de experimentos baseados em documentos de requisitos / ExpVVT: a tool to support the conduction of experiments based on requirements documents
The creation and update of knowledge bases with data that provide evidences of the efficacy, or non-efficacy, of software methods, techniques or products can be facilitated by experimental studies and their replications in diverse contexts, so that the knowledge base can grow and be consolidated. However, replications generate great amount of data which must
