13. "Segmentação de imagens e validação de classes por abordagem estocástica" / Image segmentation and class validation in a stochastic approach
An important stage of the automatic image analysis process is segmentation, that aims to split an image into regions whose pixels exhibit a certain degree of similarity. Texture is known as an efficient feature that provides enough discriminant power to differenciate pixels from distinct regions. It is usually defined as a random combination of pixel intensi

14. Otimização multiobjetivo para a operação de sistemas urbanos de abastecimento de agua
The proper operation of the urban water supply systems has a direct impact on the water to be provided to the quality consumers. The optimization of these systems appears as an alternative to search efficient and also efficient solutions, thus guaranteeing the management of the systems. Many research works have been reported in the literature describing appl

15. Redução de perdas na distribuição de energia eletrica pelo metodo GRASP
Energy is continuously dissipated in electric power systems due to electrical resistance in the lines and equipment. Losses amount to around 7% of total energy production, 2% in transmission and 5% in distribution. The problem of loss minimization tries to find a network configuration where the amount of losses is reduced. This work proposes a procedure that

16. Coupled two-way clustering analysis of gene microarray data
We present a coupled two-way clustering approach to gene microarray data analysis. The main idea is to identify subsets of the genes and samples, such that when one of these is used to cluster the other, stable and significant partitions emerge. The search for such subsets is a computationally complex task. We present an algorithm, based on iterative cl

17. The HSSP database of protein structure-sequence alignments and family profiles.
HSSP (http: //www.sander.embl-ebi.ac.uk/hssp/) is a derived database merging structure (3-D) and sequence (1-D) information. For each protein of known 3D structure from the Protein Data Bank (PDB), we provide a multiple sequence alignment of putative homologues and a sequence profile characteristic of the protein family, centered on the known structure. The

18. Spreadsheet Method for Evaluation of Biochemical Reaction Rate Coefficients and Their Uncertainties by Weighted Nonlinear Least-Squares Analysis of the Integrated Monod Equation
A convenient method for evaluation of biochemical reaction rate coefficients and their uncertainties is described. The motivation for developing this method was the complexity of existing statistical methods for analysis of biochemical rate equations, as well as the shortcomings of linear approaches, such as Lineweaver-Burk plots. The nonlinear least-squares
