1. Sparse Estimation of the Precision Matrix and Plug-In Principle in Linear Discriminant Analysis for Hyperspectral Image Classification
ABSTRACT In this paper, a new method for supervised classification of hyperspectral images is proposed for the case in which the size of the training sample is small. It consists of replacing in the Mahalanobis distance the maximum likelihood estimator of the precision matrix by a sparse estimator. The method is compared with two other existing versions of L

2. Diagramas de influência e teoria estatística / Influence Diagrams and Statistical Theory
The main objective of this work is to analyze the controversial concept of information in Statistics. To do so, firstly the concept of information according to Basu is presented. Next, the analysis is divided in three parts: information in a data set, information in an experiment and influence diagrams. In the first two parts, we always tried to define prope

3. Test of hypothesis in majoritarian election / Testes de hipóteses em eleições majoritárias
The problem of inference about a proportion, widely explored in the statistical literature, plays a key role in the development of several theories of statistical inference and, invariably, is the object of investigation and discussion in comparative studies among different schools of inference. In addition, the estimation of proportions, as well as test of

4. Experimental determination and thermodynamic modeling of equilibrium phase data of binaries and ternary mixtures containing acetone, water and cumene / Determinação experimental e modelagem termodinamica de dados de equilíbrio de fases de misturas binarias e ternaria contendo acetona, agua e cumeno
On projecting separation processes it is essential the knowledge of the behavior of the phases in equilibrium. The present work involved the study of the phase equilibrium of mixtures containing acetone, water and cumene, which are very important in the phenol industry. The components water and cumene are partially miscible, and in the distillation of the mi

5. A tutela dos direitos da personalidade por meio da aplicabilidade direta do princÃpio da dignidade da pessoa humana nas relaÃÃes de direito privado
This paper studies the protection system of the personality rights within the Brazilian legal system aiming at demonstrating the likelihood of a direct application of the constitutional principle of the dignity of the human being to the private law relationships. Such possibility is derived from the verification in the paradigmatic change in the coding exper

6. BAYESIAN LEARNING FOR NEURAL NETWORKS / APRENDIZADO BAYESIANO PARA REDES NEURAIS
This dissertation investigates the Bayesianan Neural Networks, which is a new approach that merges the potencial of the artificial neural networks with the robust analytical analysis of the Bayesian Statistic. Typically, theconventional neural networks such as backpropagation, have good performance but presents problems of convergence, when enough data for t

7. Determinação experimental de dados de equilibrio liquido-vapor de misturas de solventes e pesticidas
This work presents a contribution to vapor-liquid equilibrium of pollutant substances, mainly solvents and pesticides. The systems were composed by solvents and intermediary compounds of pesticides formation as DDT (benzene, cyclohexane and chlorobenzene). It was studied four systems at two of pressures 300 and 760 mmHg being three binaries (benzenecyclohexa

8. Estudo da incineração catalitica de compostos volateis organicos em planta piloto
The work presents the study of oxidation of hidrogen over Pallladium supported on Alumina. The catalyst was prepared by impregnation of the precursor salt PD CL IND. 2 on Alumina particles sized by extrusion and sintering. The salt decomposing at the surface was done by thermal treatment at the temperature of 400 DEGREES C followed by reduction with hydrogen

9. DESEMPENHO DE MODELOS RACIONAIS NA IDENTIFICAÇÃO DE ESPECTROS DE POTÊNCIA DE GRANDE RESOLUÇÃO / PERFORMANCE OF RATIONAL MODELS IN THE IDENTIFICATION OF HIGH RESOLUTION POWER SPECTRA
In many engineering problems, the power density spectra of random signals, with highly periodic components, have to be measured, very often this problem is reduced to the one of identifying the unknown power spectrum with a rational function. The identification techniques differ from each other only by the statistical criteria of the procedures used to estim

10. The optimization principle in phylogenetic analysis tends to give incorrect topologies when the number of nucleotides or amino acids used is small
In the maximum parsimony (MP) and minimum evolution (ME) methods of phylogenetic inference, evolutionary trees are constructed by searching for the topology that shows the minimum number of mutational changes required (M) and the smallest sum of branch lengths (S), respectively, whereas in the maximum likelihood (ML) method the topology showing the highest m

11. A stochastic approximation algorithm with Markov chain Monte-Carlo method for incomplete data estimation problems
We propose a general procedure for solving incomplete data estimation problems. The procedure can be used to find the maximum likelihood estimate or to solve estimating equations in difficult cases such as estimation with the censored or truncated regression model, the nonlinear structural measurement error model, and the random effects model. The procedure

12. Multilocus Behavior in Random Environments I. Random Levene Models
In this paper the consequences of natural selection acting on several loci simultaneously in a spatially fluctuating environment are described. The fitnesses of the genotypes are assumed to be additive both within and between loci. The environment is assumed to be made up of a very large (effectively infinite) number of patches in which fitnesses are assigne
