13. Generalización de modelo digital de elevación condicionada por puntos críticos de terreno
Digital Elevation Models (DEMs) are essential geomatic products in the study, management and administration of the territory. Uses and availability of high resolution data reveal a steady growth in recent decades allowing several analyses to qualify and quantify characteristics of the territory. Despite the increasing availability of the elevation data, terr

14. Dynamic load-balancing : a new strategy for weather forecast models
Weather forecasting models are computationally intensive applications and traditionally they are executed in parallel machines. However, some issues prevent these models from fully exploiting the available computing power. One of such issues is load imbalance, i.e., the uneven distribution of load across the processors of the parallel machine. Since weather

15. Estudo comparativo entre o modelo dinâmico BRAMS e os modelos estatísticos MOS e MOC
Some variables predicted by Weather Numerical Models are frequently influenced by errors. Such errors occurs not only to the assumptions used in the construction of the model equations of physics/dynamics, but also by the topography used. This work compares two statistical post-processing methods Model Outuput Statistics (MOS) and Model Outuput Calibration (

16. Construct validity of behavioral models of anxiety: where experimental psychopathology meets ecology and evolution
In experimental psychopathology, construct validity is usually enhanced by addressing theories from other fields in its nomological network. In the field of anxiety research, this construct is related to antipredator behavior, conserved across phylogeny in its functions and neural basis, but not necessarily on its topography. Even though the relations betwee

17. Influência de níveis de base nas características morfossedimentares das bacias dos rios das Velhas e Jequitaí (MG)
The Velhas and Jequitaí river basins have together an asymmetric shape that drain northward from Quadrilátero Ferrífero to the northern Minas Gerais State. These two basins are affluent of São Francisco river in its right margin. The headwaters of Velhas and Jequitaí rivers are dominated by quartzites ridges structured during the Brazilian orogenic cycl

18. ZIMORA - UM MODELO NUMÉRICO 3D DE DISPERSÃO ATMOSFÉRICA / ZIMORA - A 3D NUMERICAL MODEL FOR ATMOSPHERIC DISPERSION
In this thesis, we presents a development and validation of a 3D numerical model for the advection-diffusion equation. Models of this kind has been developed for scientific investigations and to support atmospheric emissions control and environmental policy decisions. To develop this model, we used the computational implementation of an explicit numerical sc

19. Simulation of optical and physiological phenomena of the human vision / Simulação de fenômenos óticos e fisiológicos do sistema de visão humana
The increase in performance of the modern computers has driven scientific work in the areas of computer simulation. Many authors use in their research commercial tools that use embedding algorithms, which sources are not provided, and it makes harder and sometimes impossible, the development of novel theories or experiments. This work explores this gap left

20. Zoneamento agroclimático para a cultura do pinus no Estado do Espírito Santo
The objective of this work is to make an agroclimatic zoning for the species Pinus elliottii var. Elliottii, Pinus caribaea var. hondurensis, Pinus taeda and Pinus oocarpa for the State of Espírito Santo, identifying areas with climatic aptitude for implantation of stand of production. It was used eteorological data of the period of 1977 to 2006, from eight

21. Distribution and diversity of leaf litter ants (Hymenoptera: Formicidae) along an elevational gradient in the Parque Estadual da Serra do Mar - Núcleo Picinguaba, São Paulo, Brazil / Distribuição e diversidade de formigas de serapilheira (Hymenoptera: Formicidae) ao longo de um gradiente elevacional no Parque Estadual da Serra do Mar-Núcleo Picinguaba, São Paulo, Brasil
Aiming to investigate the influence of the elevation in topography on the myrmecological leaf litter fauna and to verify if there is a richness pattern for the investigated gradient, I studied the distribution of these ants along an elevational gradient in the Núcleo Picinguaba of the Serra do Mar State Park, Ubatuba, SP. For this, I adopted six elevational

22. Avaliação altimétrica dos dados SRTM para a região amazônica / Altimetric evaluation of SRTM data for the Amazon region
In large areas of forest cover, such as the Amazon region, there is an absence of detailed topographical charts. It can be explained by the lack of reliable data at a reasonable cost. The Digital Elevation Model (DEM) obtained by the Shuttle Radar Topographic Mission (SRTM) can be considered as the best topographical information available for a large part of

23. FINISHING STEERS SYSTEMS: BIO-ECONOMY AND MODEL EVALUATION FOR PREDICTING ANIMAL PERFORMANCE / SISTEMAS DE TERMINAÇÃO DE NOVILHOS DE CORTE: BIOECONOMICIDADE E AVALIAÇÃO DE MODELOS PARA A PREDIÇÃO DO DESEMPENHO ANIMAL
This work presents the bio-economical evaluation of beef cattle production systems used by farmers in the state of Rio Grande do Sul. Animal production, pasture dynamics and economically related results of two agriculturally integrated systems were studied according to topography, and a third system based on improved native pasture. In order to do this, stee

24. Análise bioclimática do bairro do Renascença II São Luis-MA: realidade e perspectiva do conforto térmico em espaços externos / Bioclimatic assessment of the Renascença II Neighborhood in São Luis Maranhão, Brazil: reality and perspective of thermal comfort in outdoors
The present research concerns about outdoors thermal comfort conditions in hot-humid climate cities, understanding that life quality is a result of the urban objects type built for the human being in an environment with specific climate and morphological characteristics. It is presented as object of study the correlation between the neighborhood Renascença
