1. Algoritmos para o planejamento da operação de sistemas modernos de distribuição de energia elétrica = : Algorithms for operation planning of modern electric distribution power systems / Algorithms for operation planning of modern electric distribution power systems
The distribution system operation planning stage is concerned with the determination of capacitor bank, transformer and voltage regulator settings. This must be accomplished considering active and reactive power injections of distributed generators and at the main substation, as well as physical and regulatory issues in order to improve the network performan

2. Feature selection and intrinsically multivariate prediction in gene regulatory networks identification / Seleção de características e predição intrinsecamente multivariada em identificação de redes de regulação gênica
Feature selection is a crucial topic in pattern recognition applications, especially in bioinformatics, where problems usually involve data with a large number of variables and small number of observations. The present work addresses feature selection aspects in the problem of gene regulatory network identification from expression profiles. Particularly, we

3. Sinalização por carboidratos em cana-de-açucar e divergencia evolutiva / Sugar signaling in sugarcane and evolution diversification
Besides act as carbon primary source in the major types of cells, sugars produced by photosynthesis acquired important functions in the course of plant s evolution like controlling growth, development, and metabolism and acting in resistance to abiotic and biotic stresses like osmotic, energetic and response to pathogens. Sugars can be signals that active si

4. Coeficientes de determinação, predição intrinsicamente multivariada e genética / Coefficient of determination, intrinsically multivariate and genetic prediction
Esta dissertação de mestrado tem como finalidade descrever o trabalho realizado em uma pesquisa que envolve a análise de expressões gênicas provenientes de microarrays com o objetivo de encontrar genes importantes em um organismo ou em uma determinada doença, como o câncer. Acreditamos que a descoberta desses genes, que chamamos aqui de genes de predi

5. Applications of bioinspired computing in bioinformatics : analyzing the role of genes and their interactions / Aplicações de computação bioinspirada em bioinformatica : investigando o papel dos genes e suas interações
This dissertation deals with genetic networks, the mechanism of control of gene activity in cells, under three different computational perspectives. Initially, as an engineering approach, a computational tool for inference of genetic networks is proposed, which is able to recover the static structure of these networks from experimental datasets. This systems

6. Redes bayesianas para inferÃncia de redes regulatÃrias de genes
With the development of functional genomics, data on a great number of species are being obtained in huge volumes. Technologies to measure the differences of the gene expression, through mRNA concentration (microarray), have become extremely popular, and their costs are decreasing. The reconstruction of genetic networks from gene expression data to study the

7. Robust stability of stochastic delayed genetic regulatory networks
Gene regulation is an intrinsically noisy process, which is subject to intracellular and extracellular noise perturbations and environment fluctuations. In this paper, we consider the robust stability analysis problem of genetic regulatory networks with time-varying delays and stochastic perturbation. Different from other papers, the genetic regulate system

8. Contingent gene regulatory networks and B cell fate specification
The B cell developmental pathway represents a leading system for the analysis of regulatory circuits that orchestrate cell fate specification and commitment. Considerable progress has been achieved within the past decade in the identification and genetic analysis of various regulatory components. These components include the transcription factors PU.1, Ikaro

9. Design of genetic networks with specified functions by evolution in silico
Recent studies have provided insights into the modular structure of genetic regulatory networks and emphasized the interest of quantitative functional descriptions. Here, to provide a priori knowledge of the structure of functional modules, we describe an evolutionary procedure in silico that creates small gene networks performing basic tasks. We used it to

10. The role of certain Post classes in Boolean network models of genetic networks
A topic of great interest and debate concerns the source of order and remarkable robustness observed in genetic regulatory networks. The study of the generic properties of Boolean networks has proven to be useful for gaining insight into such phenomena. The main focus, as regards ordered behavior in networks, has been on canalizing functions, internal homoge

11. HOX Pro: a specialized database for clusters and networks of homeobox genes
It is now clear that the homeobox motif is well conserved across metazoan phyla. It has been established experimentally that a subset of genes containing this motif plays key roles in the orchestration of gene expression during development. Auto- and cross-regulatory functional interactions join homeobox genes into genetic networks. We have developed a speci

12. Prediction and measurement of an autoregulatory genetic module
The deduction of phenotypic cellular responses from the structure and behavior of complex gene regulatory networks is one of the defining challenges of systems biology. This goal will require a quantitative understanding of the modular components that constitute such networks. We pursued an integrated approach, combining theory and experiment, to analyze
