13. STUDY OF TURBULENT DIFUSION EMPLOYING LAGRANGIAN STOCHASTIC MODELS / ESTUDO DA DIFUSÃO TURBULENTA EMPREGANDO MODELOS ESTOCÁSTICOS LAGRANGEANOS
In this work, the Lagrangian stochastic particle model LAMBDA is utilized to simulate the dispersion and the transport of contaminants under different atmospheric conditions. The analysis employs three different field experiments of atmospheric diffusion: the Copenhagen experiment, which was accomplished in unstable conditions, the Prairie Grass experiment i

14. Control+c: autoria na rede
Ctrl+C Authorship on the Net studies the new formats of creation that emerged from the Internet. By aiming beyond the discussions around a legal point of view, this work focusses on asthetic and critical parameters of online art experiences, which point towards the redefinition of the concept of authorship in the realm of digital media e the very context of

15. A model of nervous system for the problem of the control of animation for direct dynamics. / Um modelo de sistema nervoso para o problema do controle de animaÃÃo por dinÃmica direta.
Direct dynamics animation consists of synthesizing the movements of a model from the specification of its physical properties (mass and moment of inertia), the conditions of bond between its contracting parties, the conditions of contact with other bodies and the forces that acts on it. This approaching has the advantage to generate animations with physical

16. 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

17. Estudo da diversidade genÃtica de raÃas caprinas do norte da ItÃlia pela anÃlise de polimorfismos no gene do hormÃnio de crescimento - GH.
Northern Italyâs rugged terrain, associated with extreme variations in temperature and precipitation, make up generally unfavorable growing conditions for large ruminants (i.e. cattle). However, husbandry of small ruminants, like the domestic goat (Capra hircus), is greatly disseminated in this region. The use of local breeds is associated with the manufact

18. Avaliação da recuperação da área degradada pela mineração de argila através do plantio de Mimosa scabrella Benth(Fabaceae), sob duas técnicas de preparação do solo, Doutor Pedrinho, SC
The reclamation of degraded areas is a set of idealized and executed actions carried out by specialists of the most different areas of the human knowledge seeking to provide the re-establishment of balanced and sustainable conditions existing previouly to the degradation of a natural system. The study area is a mine of refractory clay of 96,14 ha that has be

19. Concepção, projeto e otimização de uma estrutura para aplicação em veículo de uso misto / Conception, Design and Optimization of an All Terrain Vehicle Structure
This research is a part of a major project witch comprises the design and building of a functional all terrain vehicle prototype. This type of vehicle is found between the pure off-road vehicles (jeeps) and sport utility vehicles (SUVs). It will also try to combine performance and comfort on and off-road. The main goal is to reach the design of a ladder fram

20. Uso de imagens Radarsat-1 para fins de mapeamento de uso da terra e cobertura do solo em ambiente tropical úmido urbano: o caso de Manaus, Estado do Amazonas. / Use of radarsat-1 data in the identification of targets related to land use and land cover in urban humid tropical region: the case of Manaus, state of the Amazon, Brazil
The use of remote sensing data acquired through Synthetic Aperture Radar has been a recent common trend for land use and land cover mapping purposes. The information derived from this kind of data has been applied to distinct related application fields, such as: urban pattern analysis and mapping, settlements identification, urban change detection and even m

21. Streamflow and sediment yield simulation within a small watershed through geoprocessing and modeling techniques. / Simulação de escoamento e de produção de sedimentos em uma microbacia hidrográfica utilizando técnicas de modelagem e geoprocessamento.
Hydrological and water quality models have been developed to evaluate the nonpoint source pollution in agricultural watershed. With this objective, SWAT (Soil and Water Assessment Tool) model was applied to simulate the streamflow and sediment yield in Ribeirão dos Marins watershed, on the Piracicaba river basin, Brazil, for the period 1999/2000. The applic

22. 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

23. SISTEMAS MÓVEIS VHF EM ÁREAS RURAIS / VHF MOBILE SYSTEMS IN RURAL AREAS
This work presents a model for VHF mobile systems coverage in rural areas. The model is based on statistical analysis of over 1400 measurements of received level from 13 base stations in Minas Gerais and Goiás. Several parameters are considered: antenna gain and height, distance, terrain irregularities, transmit power and threshold level. Existing estimatio
