1. Inspection of a Rectangular Plate Dynamics Under a Moving Mass With Varying Velocity Utilizing BCOPs
AbstractThis research is dedicated to the inspection of a thin rectangular plate dynamic behavior traversed by an accelerated moving mass. BCOPs (boundary characteristic orthogonal polynomials) are utilized to treat the constitutive equation of plate vibration for different boundary conditions. Comprehensive parametric surveys are carried out to shed light o

2. Analyzing genotype-by-environment interaction using curvilinear regression
In the context of multi-environment trials, where a series of experiments is conducted across different environmental conditions, the analysis of the structure of genotype-by-environment interaction is an important topic. This paper presents a generalization of the joint regression analysis for the cases where the response (e.g. yield) is not linear across e

3. Estudo da produção de leite de caprinos utilizando modelos de regressão aleatória / Study of goat milk production using random regression models
Data from the herd of goat industry, Federal University of Viçosa were used to evaluate the factors that influence milk production on the control (PLDC) and content of the Milk constituents (percentages of protein, fat, lactose and total solids in days of collection) in dairy goats fitness, define the best model of random regression using Legendre polynomia

4. Operational Tau approximation for a general class of fractional integro-differential equations
In this work, an extension of the algebraic formulation of the operational Tau method (OTM) for the numerical solution of the linear and nonlinear fractional integro-differential equations (FIDEs) is proposed. The main idea behind the OTM is to convert the fractional differential and integral parts of the desired FIDE to some operational matrices. Then the F

5. Banco Central e preferências assimétricas : uma aplicação de sieve estimators para os EUA e o Brasil
Uma questão interessante na política monetária é se os Bancos Centrais dão pesos iguais para desvios positivos e negativos da inflação e do hiato do produto das suas respectivas metas. Para responder à esta questão, estimou-se a função perda da autoridade monetária não parametricamente através do método de sieve estimator, expandindo-a atravé

6. Zeros of orthogonal polynomials on the real line / Zeros de polinomios ortogonais na reta real
Results concerning the behaviour of zeros of orthogonal polynomials are obtained. It is known that they are real and distinct and play as important role as node of the most frequently used rules for numerical integration, the Gaussian quadrature formulae. Result about the location and monotonicity of the zeros, considered as functions of parameters involved

7. Zeros of Jacobi-Sobolev orthogonal polynomials following non-coherent pair of measures
Zeros of orthogonal polynomials associated with two different Sobolev inner products involving the Jacobi measure are studied. In particular, each of these Sobolev inner products involves a pair of closely related Jacobi measures. The measures of the inner products considered are beyond the concept of coherent pairs of measures. Existence, real character, lo

8. Implicit methods for surface reconstruction from point clouds / Métodos implícitos para a reconstrução de superfícies a partir de nuvens de pontos
A reconstrução de superfícies a partir de nuvens de pontos faz parte de um novo paradigma de modelagem em que modelos computacionais para objetos reais são reconstruídos a partir de dados amostrados sobre a superfície dos mesmos. O principal problema que surge nesse contexto é o fato de que não são conhecidas relações de conectividade entre os pon

9. Estimativas de funÃÃes de covariÃncia para caracterÃsticas de crescimento da raÃa tabapuà utilizando modelo de regressÃo aleatÃria / Estimates of service for covariÃncia characteristics of growth of race tabapuà using model regressÃo random
The study used 28,873 weight records taken along the life of 6.471 animals of the race TabapuÃ, finery birth to 660 days of age, belonging to the animal archives of the Brazilian Association of Zebu Breeders (ABCZ) to estimate the covariÃnce functions using the models of random regression. The genetic, addictive direct an permanent environmental effects we

11. Transporte em nanoestruturas: mÃtodos de movimento Browniano e teoria de circuitos
The results presented in this thesis can be divided into two parts. In the first one we study a class of Brownian motion ensembles (BME) obtained from the general theory of matricial Markovian stochastic processes of random matrix theory. The ensembles are characterized by a Fokker-Planck equation and are closely related to Hamiltonians of Calogero-Sutherlan

12. Study of the mechanical behaviour of mouth protectors prepared with ethylene and vinyl acetate copolymer: experimental model of dental arches produced with epoxy / "Estudo do comportamento mecânico de protetores bucais confeccionados em copolímero de etileno e acetato de vinila: modelo experimental de arcos dentais obtidos em epóxi"
An experimental model of dental arch, moulded in epoxy, was used to study the mechanic behaviour of a copolymer of ethylene and vinyl acetate (EVA), in the form of a flat plaque or mouth protector in function of three variables: thickness, temperature and the absence or presence of artificial saliva. The evaluation of the mechanical behaviour of EVA, as a pl
