1. Continuously variable rating: a new, simple and logical procedure to evaluate original scientific publications
OBJECTIVE: Impact Factors (IF) are widely used surrogates to evaluate single articles, in spite of known shortcomings imposed by cite distribution skewness. We quantify this asymmetry and propose a simple computer-based procedure for evaluating individual articles. METHOD: (a) Analysis of symmetry. Journals clustered around nine Impact Factor points were sel

2. Método de Descida para problemas de otimização multiobjetivo / Descente Methods for Problem of Multiobjetivo Optimization
Neste trabalho, estudamos o método de descida para problemas de otimização multiobjetivo, para o qual introduzimos uma relação de ordem induzida por um cone fechado e convexo. Estudamos como calcular uma direção de descida e provamos que todo ponto de acumulação da sequência gerada pelo método de descida com busca de Armijo é fracamente eficiente

3. Optimum design applied to electrooptic modulators / Projeto ótimo de moduladores eletroópticos
Many design developments involve the optimization of several objective functions. These objective functions are often conflicting with each other and they cannot be simply aggregated into only one function to be optimized. This type of problem is known as the multiobjective optimization problem, for which the solution is a set of points known as Pareto optim

5. Nuvem de partículas aplicada à seleção de atributos
Abstract: The particle swarm optimization (PSO) algorithm is a recently developed metaheuristic technique and belongs to the category of swarm intelligence techniques. The swarm intelligence concepts are inspired by the social behavior of flocking animals such as swarms of birds, ants and fish school. PSO is a population based algorithm that exploits a popul

6. Search for IMRT inverse plans with piecewise constant fluence maps using compressed sensing techniques
An intensity-modulated radiation therapy (IMRT) field is composed of a series of segmented beams. It is practically important to reduce the number of segments while maintaining the conformality of the final dose distribution. In this article, the authors quantify the complexity of an IMRT fluence map by introducing the concept of sparsity of fluence maps and
