13. Avaliação de perfis atmosféricos de rádio ocultação GPS do satélite CHAMP sobre a América do Sul
Com o advento dos satélites artificiais Global Positioning System (GPS) em conjunto com os satélites Low Earth Orbiting (LEO), surge a Rádio Ocultação GPS (RO GPS), técnica que permite obter remotamente perfis atmosféricos com boas perspectivas para aplicações em modelagem numérica de tempo. O satélite LEO denominado Challenging Minisatellite Payl

14. Proposta de Monitoramento dos Processo do Meio Físico em Obras Viárias. / Monitoring Proposal of Physical Processes in road work.
O presente trabalho apresenta uma avaliação dos processos do meio físico em construções rodoviárias, materializada em dois estudos de caso e com isso visa contribuir com uma proposta de monitoramento desses processos, intensificados ou deflagrados pelas construções viárias. No primeiro estudo de caso abordou-se a rodovia GO-309, localizada próximo

15. Caracterização geofísica de alvos rasos com aplicações no planejamento urbano e meio ambiente: estudo sobre o sítio controlado do IAG/USP / Geophysics characterization of shallow targets with applications in the urban planning and environmental: Study on the Shallow Geophysical Test Site of IAG/USP.
The implantation of the Shallow Geophysical Test Site (SCGR) of the Astronomy, Geophysics and Atmospheric Sciences Institute (IAG), from University of Sao Paulo (USP), is a mark in national geophysical history. It is the first site Shallow geophysical study site installed in Brazil. This Test Site is located next to Physics Institute in front of IAG/USP, com

16. Spatial analysis of plutonics bodies of mineiro belt trough integration of geological, airbone geophysical data and geochemical data / Analise espacial dos corpos plutonicos do cinturão mineiro atraves da integração de dados geologicos, aerogeofisicos e geoquimicos
Airborne geophysical data acquired over the Mineiro Belt in the southern portion of the São Francisco Craton, Minas Gerais, Brazil display patterns not previously identified by geological field mapping. The lack of rock exposures and connections among rock formations at surface poses problems for regional geologic mapping and interpretation, which are diffi

17. O horizonte regional do Brasil e a construção da América do Sul (1990-2005)
This dissertation seeks to show that Brazils regional horizon have evoluted towards its history. Brazil was American, then Latin American, and nowadays tries to stamp the south-americanity into its international identity. Emphasizes that this option for South America, frequently presents in official speeches, is complemented with several actions that lend a

18. RegressÃo simbÃlica via programaÃÃo genÃtica: um estudo de caso com modelagem geofÃsica
Symbolic regression, which is in principal the handling of mathematical expressions for finding a function that describes a data set, was until recently carried out exclusively by humans. But now, several computational techniques of symbolic regression automatization have appeared. One of these techniques is genetic programming, a subarea of evolutive comput

19. Integration of remote sensing (SRTM and RADARSAT-1) geology, gravimetry and magnetometry date as an aid to a morphostructural study in the Uatumã River area, Amazon Basin / Integração de dados de sensoriamento remoto (SRTM e RADARSAT-1), geologia, gravimentria e magnetometria para estudo morfoestrutural da área do Rio Uatumã, Bacia do Amazonas
Drainage network automatically extracted from a SRTM digital elevation model was combined with geologic, gravity and magnetometry data for morphostructural study in the region of the Uatumã River, Amazonas Sedimentary Basin. Data interpretation allowed the identification of different drainage patterns, including trellis, pinnate, contorted, annular and angu

23. Ambiente de gerenciamento de imagens e dados espaciais para desenvolvimento de aplicações em biodiversidade
There is a wide range of environmental applications requiring sophisticated management of several kinds of data, including spatial data and images of living beings. However, available information systems offer very limited support for managing such data in an integrated manner. On the one hand, environmental applications based on Geographic Information Syste

24. LabSis : um ambiente para desenvovimento de aplicações sismicas Matlab
The Matlab package is a tool of widespread use in the academic environment, because of its advantages in simple direct programming, graphs and visualization tools. It allows initial implementations of algorithms and procedures very quickly in a series of applications. As a counterpar to the above good qualities, Matlab programs do not exhibit the computation
