1. Land-use influence on the soil hydrology: An approach in upper Grande River basin, Southeast Brazil
RESUMO A Bacia do Alto Grande (ARG) é responsável pela drenagem de vários rios no sudeste do Brasil, sendo uma região hidrológica de grande importância para o Sistema Elétrico Brasileiro. Portanto, estudos sobre a disponibilidade de água nesta região são indispensáveis para uma melhor tomada de decisão na gestão dos recursos hídricos. O objetiv

2. GERAÇÃO PROCEDURAL DE CENÁRIOS 3D DE CÂNIONS COM FOCO EM JOGOS DIGITAIS / GERAÇÃO PROCEDURAL DE CENÁRIOS 3D DE CÂNIONS COM FOCO EM JOGOS DIGITAIS / PROCEDURAL GENERATION OF 3D SCENES FEATURING CANYONS FOCUSED ON DIGITAL GAMES / PROCEDURAL GENERATION OF 3D SCENES FEATURING CANYONS FOCUSED ON DIGITAL GAMES
Esta dissertação propõe um método procedural não assistido, baseado em técnicas de computação gráfica, visão computacional e busca em grafos, para a geração de cenários 3D de cânions com foco em jogos digitais. Para definir as características a serem reproduzidas, foram analisadas diversas imagens de cânions reais chegando-se em dois modelos,

3. VECTORIAL GEOGRAPHIC DATA VISUALIZATION ON MULTI-RESOLUTION TERRAIN / VISUALIZAÇÃO DE DADOS GEOGRÁFICOS VETORIAIS SOBRE TERRENOS EM MULTI-RESOLUÇÃO
This work aims to integrate the graphical representation of vectorial data found in Geographic Information Systems (GIS) and the visualization for multi-resolution 3D terrain models. The multi-resolution approach on terrain rendering brings some difficulties on the process of rendering the vectorial data in a consistent manner, since these data, in general,

4. Geology of high pressure granulites of Carvalhos Klippe, southern Brasília Belt / Geologia dos granulitos de alta pressão da Klippe Carvalhos, extensão sul da Faixa Brasília
At the top of Andrelândia Nappes System, southern border of São Francisco craton, occur nappes formed dominantly by metasedimentary rocks with subordinated metabasics and metaultramafics which record metamorphism of high pressure granulite facies in the Ediacaran. These nappes are Três Pontas - Varginha, Pouso Alto and Klippen Airuoca and Carvalhos. In Ca

5. Estratigrafia e petrogênese das sequências vulcânicas paleoproterozóicas na região de São Félix do Xingu (PA), Província Mineral de Carajás / Stratigraphy and petrogenesis of the paleoproterozoic volcanic sequences in the São Félix do Xingu (PA) region, Carajás Mineral Province
Near the São Félix do Xingu city, centersouth portion of the Pará state, in the context of the Carajás Mineral Province, occur extensive Paleoproterozoic volcanoplutonism (1.88 1.87 Ga) exceptionally well-preserved and grouped in the Sobreiro and Santa Rosa formations. These suites are generically correlated to Uatumã Supergroup volcanoplutonism, a magm

6. Influência das mudanças do uso e cobertura da terra no escoamento superficial e produção de sedimentos na região da bacia do alto rio Xingu / Land use and land cover changes impacts on the surface runoff and sediment yield in the Xingu river basin
This work had as objective to analyze the land use and land cover changes in the Suiá-Miçu river basin and to evaluate its impacts in the surface runoff generation and sediment yield. The Suiá-Miçu River is located in the north part of Mato Grosso State, it is a Xingu River tributary and is inserted in the Amazon River drainage basin. Three time periods

8. The performance of a diesel engine using diesel and biodiesel mixtures / Desempenho Comparativo de um Motor de Ciclo Diesel Utilizando Diesel e Misturas de Biodiesel
Brazil is considered a country of an incommensurable biodiversity, justifying in this way, its enormous variety in oleaginous. It is considered that, in a close future, the petroleum reservations economically viable will tend to the shortage. Beside it, the exacerbated current price levels of the petroleum barrel in the international market, the possibility

9. Processamento e interpretação de dados 2D e 3D de GPR :aplicações no imageamento de feições kársticas e estruturas de dissolução no campo de petróleo de Fazenda Belém-CE
In Fazenda Belém oil field (Potiguar Basin, Ceará State, Brazil) occur frequently sinkholes and sudden terrain collapses associated to an unconsolidated sedimentary cap covering the Jandaíra karst. This research was carried out in order to understand the mechanisms of generation of these collapses. The main tool used was Ground Penetrating Radar (GPR). Th

10. Caracterização macro, meso e microscópica das estruturas frágeis do corpo arenítico conglomerático da região de Santana do Acaraú (CE) e seu embasamento circundante
The structural framework of the sedimentary basins usually plays an important role in oil prospects and reservoirs. Geometry, interconectivity and density of the brittle features developed during basin evolution could change the permo-porous character of the rocks involved in generation, migration and entrapment of fluid flow. Once the structural characteriz

11. As dunas eólicas de Natal/RN: datação e evolução
The main purpose of this study is to present complementary information on eolian systems that occur in the Center-South portion of the city of Natal, Rio Grande do Norte State, Brazil. The investigation focused on the identification of eolian units, absolute luminescence dating of eolian sediments, to geophysical analysis by Ground Penetrating Radar (GPR), a

12. Geoprocessamento aplicado a determinacao de volume e area do reservatorio hidreletrico de Serra da Mesa com imagens JERS-1/SAR / Geoprocessing applied to volume and area determination of Serra da Mesa hydroelectrical reservoir using JERS-1/SAR images
This paper presents a method for the determination of flooding parameters in hydroelectrical reservoirs. The method is based on the integration of Digital Terrain Model (DTM)and Remote Sensing data derived from JERS-1/SAR. The area and volume of the reservoir, considering different water levels, were determined using SPRING, a Geographical Information System
