1. Genetic divergence and combined selection for traits that provide high agronomic performance in common bean lines
ABSTRACT The selection of common bean lines with intermediate cycle, upright plant architecture and high grain yield is an important goal of breeding programs. This study proposes to examine the genetic diversity of common bean genotypes for agronomic traits, select superior genotypes for traits that provide high agronomic performance and define promising cr

3. School Achievement Test: normative data for a representative sample of elementary school children
The present study established norms for the spelling and arithmetic subtests of the School Achievement Test (Teste do Desempenho Escolar [TDE]) in two Brazilian cities located in the state of Minas Gerais and compared the results with those obtained from the original normative sample. A stratified proportional sample of 1,034 students from Belo Horizonte and

5. Constant Boundary Elements on graphics hardware: a GPU-CPU complementary implementation
Numerical simulation of engineering problems has reached such a large scale that the use of a parallel computing approach is required to obtain solutions within a reasonable time. Recent efforts have been made to implement these large scale computational tasks on general-purpose programmable graphics hardware (GPGPU). The Graphics Processing Unit (GPU) is sp

9. Construção do termo geral da progressão aritmética pela observação e generalização de padrões
Today it has been disclosed the poor performance of High School students in learning the Algebra. On the other hand, the results of researches, such as Vale e Pimentel (2005) and Machado (2006) among others, emphasized the importance of working with the observation and generalization of patterns to develop the algebraic thinking, which can help to overcome t

10. Controle automatico eletronico de ganho com supressão de transientes aplicado a EDFAs em redes opticas WDM / Eletronic automatic gain control with transient suppresion applied over WDM optical networks
IIn WDM optical communication systems erbium doped fiber amplifiers (EDFA) have an essential function, enabling amplification of simultaneous channels independently of transmit rate. The majority of current WDM systems use point to point configuration operating with a fixed number of channels over the optical link. However, the new generation optical systems

11. ESTIMAÇÃO DE HARMÔNICOS/INTER-HARMÔNICOS: UMA ABORDAGEM MULTITAXA
This dissertation discusses parameter estimation of harmonics/inter-harmonics of electrical signals under time-varying conditions. Two new suitable approaches for processing this kind of signals are proposed. The first one is based on phase error of DFT (Discrete Fourier Transform) result, occurring due to the frequency deviation of input signal. This method
