1. QUALITY OF SUGARCANE MECHANIZED PLANTING
ABSTRACT: The quality of the sugarcane plantation affects the plantation longevity, yield and production costs. Therefore, this study aimed to evaluate the quality of sugarcane mechanized planting in day and night shifts. The mechanized planting was carried out in Ivinhema, MS, Brazil. For the evaluation of pre-planting seedlings, were collected 40 billets i

2. QoS management in smart grids: a Markovian approach
In Smart Grids, a variety of new applications are available to users of the electrical system (from consumers to the electric system operators and market operators). Some applications such as the SCADA systems, which control generators or substations, have consequences, for example, with a communication delay. The result of a failure to deliver a control mes

3. Decaimento dos autovalores de operadores integrais positivos gerados por núcleos Laplace-Beltrami diferenciáveis / Eigenvalue decay of positive integral operators generated by Laplace-Beltrami differentiable kernels
Neste trabalho obtemos taxas de decaimento para autovalores e valores singulares de operadores integrais gerados por núcleos de quadrado integrável sobre a esfera unitária em \ R POT. m+1\ , m 2, sob hipóteses sobre ambos, certas derivadas do núcleo e o operador integral gerado por tais derivadas. Este tipo de problema é comum na literatura, mas as hip

5. Comportamento assintótico para soluções de certas equações diferenciais funcionais periódicas / Asymptotic behavior of solutions to certain periodic functional differential equations
We are interested in the study of the asymptotic behavior of the solutions of a class of linear autonomous Functional Differential Equations (FDE) of neutral type, where the coeficients of the non neutral part are periodic functions with common period w and the time delays are multiples of w. We employ the spectral theory for linear operators applied to the

6. "Multiresolution design of morphological operators from examples" / "Projeto multirresolução de operadores morfológicos a partir de exemplos"
The task of finding a good solution for an image processing problem is often very complex. It usually depends on the knowledge, experience and intuition of an image processing specialist. This complexity has served as a motivation for some research groups to create techniques for automatically designing image operators based on a collection of input and outp

7. Dimensionality reduction using mean conditional entropy applied for bioinformatics and image processing problems / "Redução de dimensionalidade utilizando entropia condicional média aplicada a problemas de bioinformática e de processamento de imagens"
Dimensionality reduction is a very important pattern recognition problem with many applications. Among the dimensionality reduction techniques, feature selection was the main focus of this research. In general, most dimensionality reduction methods that may be found in the literature privilegiate cases in which the data is linearly separable and with only tw

8. Permanent plot selection in moutainous ecosystems / Seleção de parcelas permanentes em ecossistemas montanhosos
A methodology for the selection of an optimal set of drainage basin with regional representativeness of the environmental variability of the studied area is presented. The methodology is based on the cluster analysis of the second order drainage basins parameterized by environmental characteristics related to the spatial pattern of the land cover, to microcl

9. Problemas de circulacao oceanica equatorial: determinacao da estrutura horizontal dos modos baroclinicos por equacoes integrais de contorno / Problems of equatorial oceanic circulation: determination of horizontal
This work contains a detailed presentation of a new methodology for the numerical simulation of tropical ocean circulation. Specifically, one considers the linearized shallow water equations on the equatorial Ò-plane, which may be used to describe the horizontal dependence of each baroclinic mode in a vertical normal mode expansion. A general boundary value

12. Characterization of parallel subtraction
Parallel subtraction is an operation defined on pairs of positive operators. In terms of electrical networks, one may pose the following problem: Given an electrical network, represented by a specified positive operator, determine the set of positive operators which when connected in parallel with the specified operator yield another prescribed operator. The
