1. Estimation and Mapping of the Received Power Level of Digital Signals TV Using Spatial Interpolation Methods
Abstract The signal digitization process of the open television system is still in progress, therefore, the study of the digital signal propagation has great importance so that broadcasters can develop and improve the transmission service. The field measurement of digital signal parameters is one of the most reliable means to analyze the signal propagation i

2. On the classification and treatment of outliers in a spatial context: A Bayesian Updating approach
Abstract Checking and treating extreme values is commonplace in modelling workflows. The main methods to manage outliers may be categorized into graphical, Kriging- and simulation-based approaches. While graphical methods usually classify outliers from a global perspective, geostatistical methods evaluate outliers in a local context. Ordinary-Kriging based a

3. Utilização da técnica de co-krigagem com inclinação máxima e altitude do terreno no delineamento de zonas de manejo: granulometria do solo e disponibilidade hídrica / Using the technique of cokriging with maximum slope of the terrain and altitude in the delineation of management zones: grain size and soil water availability
In Brazil, few studied are related about soil sampling strategies in areas with more than one type soil and various features of the landscape, these strategies are important to map the spatial variability of physical attributes: size fractions, as well as the correlation of these with geomorphologic parameters: altitude and maximum slope of the sampled area

4. DETECÇÃO DE REGIÕES SUSPEITAS E CLASSIFICAÇÃO DE MASSAS EM MAMOGRAFIAS DIGITAIS UTILIZANDO DESCRIÇÃO ESPACIAL COM FUNÇÃO VARIOGRAMA / DETECTION OF SUSPICIOUS REGIONS AND CLASSIFICATION OF MASSES DESCRIPTION USING DIGITAL MAMMOGRAPHY IN SPACE VARIOGRAM FUNCTION
A mamografia é um exame de mama, utilizado de forma preventiva ao câncer de mama e também como método diagnóstico. Este exame, que consiste em uma radiografia das mamas, permite a detecção do câncer. O objetivo deste trabalho é utilizar técnicas de processamento de imagens e visão computacional para auxiliar especialistas na detecção de regiões

5. Spatial and temporal soil moisture behavior at a watershed of the Mantiqueira Range, Minas Gerais. / âCOMPORTAMENTO ESPACIAL E TEMPORAL DA UMIDADE DO SOLO NUMA BACIA HIDROGRÃFICA NA SERRA DA MANTIQUEIRA, MINAS GERAISâ.
The qualitative and quantitative evaluation of the use and exploration of water resources at a watershed has been relevant on environmental context. The soil moisture consists of an important hydrological variable that determine the evapotranspiration and surface runoff production. This work aimed to analyze the spatial and temporal behavior of the soil mois

6. Caracterização de reservatorios com tecnicas de otimização combinatorial
Stochastic modeling has received increasing attention in the oil industry, being established as a ordinary tool for helping the elaboration of development plans in producing reservoirs. Combinatorial optimization techniques, such as simulated annealing, allow to produce equiprobable models of reservoir variables, reproducing a priori any characteristic that
