Estratégias baseadas em análise multicritério para seleção de tecnologia de acesso de primeira milha em padrão ISDB-T

Esta Tese propõe o desenvolvimento de uma estratégia de planejamento que combina: caracterização de carga de uma aplicação típica de TV Digital, extração de vetor peso por meio de redes de crença e tomada de decisão multicriterio a partir da aplicação de métodos analíticos (TOPSIS e ELECTRE III), para fornecer suporte a decisão junto a provedores de serviços, objetivando-se permitir optar-se por uma tecnologia para canal de retorno (ADSL2+, PLC, WiMAX e 3G), considerando a carga típica de um cenário de TV Digital interativo, padrão ISDB-T. A estratégia proposta apresenta cinco etapas, sendo estas: definição dos canais de retorno e das métricas de desempenho, realização de medições das tecnologias de acesso em cenários reais, simulação dos dados em ambientes simulados, aplicação de técnicas de correlação de dados para geração do vetor peso e aplicação de métodos analíticos de tomada de decisão para escolha da melhor tecnologia a ser implantada em determinado cenário. Como resultado principal se obteve um modelo genérico e flexível que foi validado através de um estudo de caso que ordenou a preferência das tecnologias avaliadas.

Geotecnologias na avaliação da suscetibilidade a movimentos de massa no município de Várzea Paulista (SP)

The disordered occupation in several cities in Brazil, is very common, especially during the rainy season, there are numerous cases of gravitational mass movements, with deads of human and builds destruction. The main objective of this work was to identify and map areas to mass movements, through the geo, the municipality of Várzea Paulista, the state of Sao Paulo. For the purpose, were prepared thematic maps of slope, geology, pedology, geomorphology and land use and occupation, which were overlaid using ArcGIS GIS Multicriteria Analysis. Each subject received a weight of influence to the outbreak of such processes and the final result was obtained map of susceptibility to mass movements of the city of Várzea Paulista. This survey found that there are many occupied areas within the city that require monitoring of the Government, especially in the rainy months, because they are in very fragile in terms of geological and geomorphological features. Considering that the data on the physical and natural aspects are scarce in the literature for this region, the results obtained in this study as well as the gathering of information of the physical and cartographic products developed, will greatly contribute to the administration of the municipality, subsidies they provide for the proper use planning and land tenure, pointing out the weak areas of the city geotechnical point of view

Proposta de traçado de alcoolduto ligando a hidrovia Tietê Paraná à refinaria do planalto paulista com uso de avaliação multicritérios e geotecnologias

From the beginning of the century, with the advent of the flex fuel car, successor fluctuations in oil prices and the rise of awareness of the impending shortage of fossil fuels, the alcohol sector begins to reappear in the panorama of national economy making Brasill reaches the point of becoming a leading exporter of this product. Ethanol assumed the role of such importance in Brazilian exports, which Petrobras through the Growth Acceleration Program (PAC) has made investments in the Brazilian pipeline network to better ensure the production of ethanol to major ports. The means of transport in pipelines are safe and inexpensive, but require careful evaluation in its implementation, they may lead to negative social and environmental impacts. Thus, the purpose of this project is to propose the best route for an ethanol pipeline connectin the Tietê-Paraná, leaving the municipality of Santa Maria da Serra (SP), to the Planalto Paulista Refinery (REPLAN), located in Paulinia (SP), belonging to the passage of ethanol export corridor, currently under revelopment. The technique used for the development of the stroke is the association of multicriteria evaluation, the geographical information system (SIG) and geotechnologies. This study presented three possible layouts for the ethanol pipeline, highlighting the best option, in addition, demonstrated the suitability of the area to receive projects of similar nature to a pipeline

Aplicação do método AHP para hierarquização de condicionantes de corrida de massa

Among the flow, the flows have the highest destructive potential, may cause disasters with a very high number of victims, as recorded in the events Caraguatatuba (SP) and the Serra das Araras (RJ) in 1967; Valeu do Rio Figueira, in Timbé do Sul (SC) between 1995 and 1996; Vale do Itajaí in Santa Catarina, in 2008, Teresópolis, Petrópolis and Nova Friburgo (RJ), in December 2010 and January 2011. This project aimed to prioritize the main determinants of inducing processes of debris flows by applying the method of decision making AHP (Analytical Hierarch Process). Therefore, the following stages of work were defined: research of the major factors of debris flows, questionnaire design method for application of AHP expert on the subject, analysis of the results obtained from calculating the ratio of consistency and preparation of proposal for hierarchical of conditions for debris flows. From the surveys it was possible to establish a relationship of conditions according to the scale of work, defining three levels: regional (1:250,000 to 1:100,000), Semi-Detail (1:50,000 to 1:25,000) and Detail (1: 10,000 or higher). The factors found were: concentration time, the flood wave, rain, landslide susceptibility (slope), drainage and development in the deposition. The project analyzed the results obtained from the questionnaires, which allowed the ranking of the constraints, contributing to weight constraints in studies of multicriteria mapping of susceptibility to the occurrence of debris flows. The study showed that the most of the analyzed datas were inconsistent because of the different opinion of the judges

Seleção de áreas potenciais para implantação da zona de processamento e exportação de Fernandópolis - SP utilizando geotecnologia

The implementation of an Export and Processing Zone (ZEPs) brings several benefits to the local, state and federal economy, but often, only socioeconomic factors are considered, apart from several other factors that should be analyzed, such as the environment. In this context of industrialization and the struggle for sustainable development, this work propose to incorporate the environmental variable in the decision process for establishing industrial areas, in particular, the ZPE in the city of Fernandópolis, São Paulo state, Brazil, by examining several physical and environmental factors such as slope intervals, geological features, pedological factors and land use. Developed using a multicriteria analysis, a model has been elaborated, where these factors have received a proportional value according with their importance, supported by a GIS tool (Geographical Information System) and remote sensing products, such as images from CBERS satellite and SRTM radar, showing the suited areas for industrial activities, considering environmental conditions. This model may assist to take better decision about the ZPE implementation area and to reduce the negative environmental impacts that would result of poorly planned locations

Qualidade ambiental dos fragmentos florestais na Bacia Hidrográfica do Rio Jundiaí-Mirim entre 1972 e 2013

The location of Jundiai-Mirim river basin, close to large urban centers and industrial parks, has contributed to the appreciation of their lands. Consequently, the region has an intense process of urbanization that resulted in an increasing environmental disturbance in the forest areas. Given the need to preserve existing natural vegetation, because the watershed is the source of water used to supply Jundiai, SP, this study evaluated changes in the environmental quality of the watershed forest fragments between 1972 and 2013. The environment quality was determined by evaluating nine indicators of environmental disturbance, obtained by techniques of Geoprocessing and integrated by Multicriteria Analysis. The results showed a constant tendency of deteriorating the environmental quality of natural vegetation between 1972 and 2013, attributed to the intense process of occupation of the watershed. It is concluded that: (a) urbanization and deforestation of natural vegetation were primarily responsible for changes in environmental quality; (b) there is a need to create public policies to preserve the natural vegetation in the watershed.
