13. Development and application of a bioeconomic efficiency index for beef cattle production in Rio Grande do Sul, Brazil
An index was developed to estimate the bioeconomic efficiency of production systems, identifying alternative scenarios that could improve their efficiency, and building isoefficiency relations in beef cattle production systems in Rio Grande do Sul. The concept of return on investment was used to develop the indicator. Scenarios regarded as efficient showed v

14. Gestão de agregados minerais : análise e subsídios para políticas públicas / Management ggregates : comparite analysis betwen Canada and Brazil and subsidies for public policies
The biophysical and social disruption caused by aggregates mining has placed it at the center of conflict scenarios, either because of advancing urbanization on the aggregates resources or because of pressures from civil society to impose restrictions on their development. The search for solutions to this problem has required of the governments a large abili

15. REQUISITOS TÉCNICOS DA QUALIDADE DO NÍVEL DE EFICIÊNCIA ENERGÉTICA APLICADO EM EDIFICAÇÃO PÚBLICA EM FASE DE PROJETO: O CASO DO CENTRO DE CONVIVÊNCIA PARA IDOSOS EM DOUTOR MAURÍCIO CARDOSO RS / THE TECHNICAL REGULATIONS OF ENERGY EFFIENCY QUALITY LEVELS APPLIED IN PUBLIC BUILDING IN THE DESIGN PHASE: THE CASE OF CONVENIENCE CENTER FOR ELDERLY IN DOUTOR MAURÍCIO CARDOSO RS
The labeling of buildings specified by technical regulations of energy efficiency quality levels presents the technical requirements and the methods for the classification of commercial buildings, services and publics regarding energy efficiency. The work consisted in the application of this regulation in the design phase of the public building the will hous

16. Avaliação da produção de sedimento na bacia hidrográfica do rio Potengi através do modelo SWAT
Anthropic disturbances in watersheds, such as inappropriate building development, disorderly land occupation and unplanned land use, may strengthen the sediment yield and the inflow into the estuary, leading to siltation, changes in the reach channel conformation, and ecosystem/water quality problems. Faced with such context, this study aims to assess the ap

17. Desenvolvimento e aplicação de procedimento metodológico em suporte ao planejamento participativo para redução de perda de solos em pequenas bacias hidrográficas com emprego da EUPS
The agrosilvipastoral activity has impacted negatively the environment worldwide, promoting soil erosion and sediment settling in water bodies. The Universal Soil Loss Equation (USLE) estimates the rates of laminar erosion (A; in ton/acre/year) by the multiplication of six parameters: A = RKLSCP (R: rainfall erosivity factor; K = soil erodibility factor; S:

18. Técnicas de otimização bi-objetivo para a determinação da estrutura de modelos NARX
The system identification aims to obtain a mathematical model that describes the behavior of a dynamic system from measurements. There are some typical steps in the process of building mathematical models from data: i) tests realization and data collection, ii) selection of the class of models, iii) structure detection, iv) parameters estimation and v) model

19. 3D routing with context awareness
The emergence of low-cost, wireless network interfaces in the market and the ever increasing growth in demand of mobile devices (such as SmartPhones, PDAs, Internet Tablets and Laptops) enabled scenarios where network services for mobile users may exist in an ad hoc fashion, with no pre-existing communications infrastructure. However, the creation of such dy

20. IDEA: um protocolo para o isolamento e desvio de anomalias em redes de sensores
The number of applications that relies on wireless sensor networks has grown fast. However those networks are vulnerable to fails and attacks that may disturb or even stop completely important information diffusion through it. In most scenarios, removing or disabling the bad nodes causing those anomalies is simply not possible. The alternative we found to so

21. Radioatividade de rochas provenientes das formações geológicas pertencentes à bacia hidrográfica do Rio Tibagi
This work is a study of the 40K and the 238U and 232Th series radioactivity in rocks measured with high resolution gamma ray spectrometry. The rocks were taken from the geologic formations in the region of the Tibagi river hydrographic basin. The course of this river cuts through the Paleozoic and Mesozoic stratigraphic sequences of the Paraná sedimentary b

22. Landscape transformation due to the building of Funil hydroelectric power station â UHE-Funil and the impact of its building on the town of Ijaci, MG / TransformaÃÃes na paisagem decorrentes da construÃÃo da usina hidrelÃtrica do Funil UHE- Funil e o impacto no municÃpio de Ijaci, MG
The building of a hydroelectric power station causes transformations in the regional landscape, in a process contrary to the long-standing movement of its formation, with negative impacts to both the fauna and flora. The establishment is defined by pre-requirements as water availability, topography and geological factors, without an integral landscape study

23. Evaluation of learner profile based on contextual interactions to adaptation of learning scenarios. / Avaliação do perfil do aluno baseado em interações contextualizadas para adaptação de cenários de aprendizagem.
The identification of characteristics of a given student that are important during the teachinglearning process has been the focus of numerous studies in recent years. Teachers, coordinators and pedagogues have defended the notion that each individual presents particular and important characteristics in the developing knowledge process. The need to adapt tea

24. APLICAÇÃO DO MÉTODO DAS DIFERENÇAS FINITAS NO DOMÍNIO DO TEMPO NA ANÁLISE DE COBERTURA EM AMBIENTES INTERIORES / APPLICATION OF FINITE DIFFERENCE TIME DOMAIN IN THE ANALYSIS OF INDOOR COVERAGE
The growing interest in broadband wireless local networks and high trans- mission rates requires an increasingly reliable modeling of radio propagation channels, specially for indoor scenarios. The use of optical methods of elec- tromagnetic field tracking along (ray) trajectories between transmission and observation points, via high-frequency analysis of sc
