O trabalho busca conhecer a forma como Campinas e Ribeirão Preto trataram o aeroporto em suas legislações municipais. Visa a proposição de medidas que possam minimizar as interferências do aeroporto no seu entorno. Avalia o processo de desenvolvimento da legislação aeronáutica, do aeroporto e seus impactos no meio urbano e do urbanismo, no país e no exterior. Aponta para a incompreensão, por parte dos municípios estudados, em relação às especificidades do aeroporto, bem como a não incorporação da legislação aeronáutica nos seus processos de planejamento urbano. Sugere um aprimoramento técnico dos profissionais que atuam nas prefeituras, a incorporação na legislação aeronáutica de medidas compensatórias dos impactos gerados pelo aeroporto, bem como a constituição de comissões para o gerenciamento das interferências entre o aeroporto e o município. / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Civil, Campinas, 2001. / Bibliografia: p. 100-113. / Inclui notas de rodapé.

Sob esse contexto, é fundamental que as decisões relacionadas à expansão da infraestrutura aeroportuária estejam inseridas em um processo sistemático de planejamento que considere os variados aspectos de ordem econômica, social e ambiental. Reconhecidamente, a ferramenta que insere critérios de sustentabilidade em Políticas, Planos e Programas é a Avaliação Ambiental Estratégica (AAE). Esta é um instrumento com procedimentos flexíveis, variando conforme a decisão estratégica em que é aplicada, cuja metodologia e abordagem apresentam ainda algumas lacunas a serem preenchidas. Assim, o objetivo do presente trabalho é realizar um estudo para elaborar uma estrutura de Plano Diretor Aeroportuário de caráter ambiental, a partir dos preceitos da Avaliação Ambiental Estratégica e do Auxílio Multicritério à Decisão (AMCD). Para isso, foram estudados os principais procedimentos e práticas desenvolvidos no âmbito do setor aeroportuário, além de serem objetos de análise específica as etapas de scoping da AAE e de Estruturação do AMCD. Como resultado foi elaborada uma metodologia, baseada nessas duas etapas das diferentes ferramentas, a ser seguida para elaboração de Planos Diretores Aeroportuários que contemplem a variável ambiental. Como estudo de caso, essa metodologia proposta foi aplicada no Plano Diretor do Aeroporto Internacional de Viracopos/Campinas, possibilitando uma análise crítica sobre como a ferramenta proposta pode impactar o planejamento em estudo / Abstract: Despite the characteristic of being an inducer of development and a key aspect to national integration, an airport is also responsible for various environmental impacts associated with its implementation and operation. In this context, it is important that the decisions related to the expansion of airports are inserted into a systematic planning process that considers the various aspects of economic, social and environmental considerations. Admittedly, the tool capable of insert sustainability criteria in Policies, Plans and Programs is the Strategic Environmental Assessment (SEA). This is an instrument with flexible procedures, varying according to the strategic decision that is applied, whose methodology and approach still have some gaps to be filled. The objective of this work is to conduct a study to develop a structure of airport master plan with environmental aspects, from the contribution of Strategic Environmental Assessment and Multiple Criteria Decision Aid (MCDA). For this, the main procedures and practices developed under the airport sector were studied, besides being objects of specific analysis the scoping step of SEA and structuring step of MCDA. As a result it was developed a methodology based on these two stages of different tools, to be followed for preparation of airport master plans that address the environmental variable. As a case study, this proposed methodology was applied in the Viracopos International Airport master plan, providing a critical analysis of how the proposed tool can impact the study planning / Mestrado / Transportes / Mestre em Engenharia Civil

Les bruits et les polluants atmosphériques émis par les avions commerciaux représentent un défi environnemental important, un problème de santé publique et une contrainte économique pour le développement durable du transport aérien. D'un autre côté, le développement économique des régions est intimement lié au secteur du transport aérien. Ce dernier agit comme un multi-capteur économique pour supporter le développement régional et desservir les grands centres. Cette réalité s'explique entre autres par le fait que la mondialisation des marchés impose l'utilisation de moyens rapides et compétitifs pour le transport des voyageurs et des marchandises. Notre approche est une modélisation mathématique du problème de choix des trajectoires de vol dans un domaine continu. La première étape dans la modélisation d'un tel problème est l'écriture des équations qui traduisent la dynamique de vol de l'avion. Ensuite, vient la modélisation est la synthèse des critères d'optimisation. Les critères qu'on a retenus dans notre travail sont la consommation de carburant (critère d'énergie) et le bruit perçu au sol (critère de la gêne occasionnée pour les riverains). En combinant les deux parties "modèle de la dynamique du vol" et "critères d'optimisation", et en intégrant d'autres contraintes liées à la sécurité du vol, on aboutit à un modèle mathématique qui appartient à la classe des problèmes non linéaires de contrôle optimal. C'est une classe difficile de problèmes d'optimisation qui pose un certain nombre de difficultés lors de la construction d'algorithmes de résolution. Pour résoudre le problème ainsi posé, deux approches distinctes peuvent être envisagées : méthodes directes et méthodes indirectes. Nous avons implémenté une méthode dite " pseudo spectrale de Gauss " pour la résolution du problème de contrôle. Le choix de cette méthode est basé sur une propriété très importante et qui garantit l'équivalence entre l'application des deux schémas : direct et indirects. Des résultats sont présentés et discutés. Nos résultats donnent des pistes sur de nouvelles procédures de vol qui minimisent le bruit et la consommation de carburant durant les phases d'atterrissage et de décollage. Par ailleurs, la résolution numérique consolide également le potentiel des approches CDA recommandées par l'OACI. Une comparaison aux procédures standards et une analyse de sensibilité aux critères est présentée / Noise and air pollution from commercial aircraft represent a significant environmental challenge, a public health problem and an economic constraint to the sustainable development of air transport. On the other hand, the economical development of the regions is closely linked to the airline industry. This fact is partly explained by the the globalization of markets that requires the use of fast and competitive means to transport people and goods. We propose a mathematical model to tackle this problem by optimizing flight paths in order to minimize noise emission and fuel consumption. The first step is to express the dynamics of flight of the aircraft. Then comes the synthesis of optimization criteria. The criteria we used in our work are the fuel consumption (criterion of energy) and the perceived noise levels at the ground (criterion of inconvenience for local residents). By combining the two previous parts, and incorporating other constraints related to flight safety, we obtain a mathematical model that belongs to a class of nonlinear optimal control problems. It is a difficult class of optimization problems that raises several difficulties during the construction of solving algorithms. Two different ways can be considered to solve this problem : direct methods and indirect methods. We have developed and implemented a direct method called "Gauss Pseudo-spectral Method" to solve the optimal control problem that we obtained. The choice of this method is based on a very important property that guarantees the equivalence between the use of two schemes : direct and indirect. Results are presented and discussed. Our results provide a new view on flight procedures that minimize noise and fuel consumption during landings and takeoffs. Moreover, the numerical solution also consolidates the potential of CDA approaches which are recommended by ICAO. A comparison with standard procedures and a sensitivity analysis are presented

The theme of this thesis is the air transport and its dramatic and dynamic development in the last twenty years. The key driving force behind this change was the deregulation of air agreements and liberalization of international markets, which took place in the seventies in the USA and in the nineties in Europe. This work addresses specific and general effects of deregulation and the development of air transport industry and aims to identify and analyze changes of its structures in space and time. One of the major and direct impacts and consequences of deregulation is that the free market allowed the emergence of new low-cost airlines, which significantly changed the structure and trends of air transport. The changes allowed for greater mobility of people, goods and capital, and also caused a partial change in consumer behaviour of individuals and institutions, and even more interconnected global economy. The source of data and information are primarily articles in professional journals written in English. Knowledge from particular analysis and research approaches to air traffic from the first part of this work is confronted with empirical research. This was based on the statistical data of air traffic in Germany, for each airport from 1991 to 2010 and verified the theoretical concepts of the general...

[pt] Nos últimos anos tem se verificado no Brasil o crescimento na utilização do transporte aéreo no Brasil, resultando no aumento do consumo dos combustíveis utilizados na aviação, como o Querosene de Aviação (QAV) e a Gasolina de Aviação (GAV). A Petróleo Brasileiro S.A. (Petrobras) como principal fornecedora de QAV no Brasil necessita analisar a distribuição logística deste derivado em São Paulo, com o objetivo de mapear gargalos e propor soluções visando atender o mercado crescente, visto a existência de aeroportos de grande fluxo de passageiros e cargas como o de Cumbica (Guarulhos), Viracopos (Campinas) e Congonhas (São Paulo). O estudo da cadeia logística do QAV representa um importante esforço para se conhecer os integrantes do sistema de distribuição, assim como identificar as limitações existentes e propor alternativas no atendimento do mercado futuro, visto a coexistência de aeroportos públicos e privados, concorrência fiscal entre Estados e atendimento aos eventos internacionais, como a Copa do Mundo FIFA (Fédération Internationale de Football Association) de Futebol, ocorrida nos meses de Junho e Julho/2014 e os Jogos Olímpicos de 2016. A utilização do Método AHP (Analytic Hierarchy Process) serviu para estruturar os fatores que impactam o suprimento de QAV no Estado de São Paulo, e subsidiar a elaboração do questionário enviado aos especialistas para avaliação dos componentes que impactarão o atendimento do mercado futuro, até 2030. Os resultados obtidos pelo estudo podem auxiliar a Petrobras na identificação dos gargalos, assim como no planejamento do atendimento do mercado, visto a sinalização por especialistas de itens que podem ser críticos no futuro. / [en] In recent years Brazil has overseen a growth in the use of air transportation, resulting in increased consumption of fuels used in aviation, such as Aviation Kerosene (Jet Fuel) and Aviation Gasoline (GAV). Petrobras, as the main supplier of jet fuel in Brazil, has seen the need to analyze the distribution logistics of this oil derivative in São Paulo, aiming to map the bottlenecks and propose solutions to meet the growing market, given the large flow of passengers and cargo in its airports such as Cumbica (Guarulhos), Viracopos (Campinas) and Congonhas (Sao Paulo). The study of jet fuel supply chain is an important effort to meet the members of the distribution system, and identify the limitations and propose alternative way of distribution in the future, since the coexistence of public and private airports, tax competition between states and attendance at international events such as the FIFA World Cup held in the months of June and July/2014 and the 2016 Olympics Games. The AHP Method was used to support the factors that impacts the supply of jet fuel in São Paulo State and the development of the questionnaire sent to experts for evaluation of the components that impact the supply of future demands, until 2030. Results from the study may help Petrobras for identifying bottlenecks, as well as for planning the supply of market demands.

With rapidly increasing datasets and more dynamic workloads, adaptive partial indexing becomes an important way to keep indexing efficiently. During times of changing workloads, the query performance suffers from inefficient tables scans while the index tuning mechanism adapts the partial index. In this paper we present the Adaptive Index Buffer. The Adaptive Index Buffer reduces the cost of table scans by quickly indexing tuples in memory until the partial index has adapted to the workload again. We explain the basic operating mode of an Index Buffer and discuss how it adapts to changing workload situations. Further, we present three experiments that show the Index Buffer at work.

In the past two decades the increase in passengers and frequency of flights has caused commercial air transportation to suffer. The system in current use was designed to satisfy different needs than the contemporary ones. Airports have failed to keep up with increased demands. Movement of passengers and aircraft have not kept pace with advances in technology. Many aircraft arriving and departing simultaneously create unnecessary delays and monetary loss to commercial airlines. The present solutions were based on new additions to existing airports as well as the creation of new airports so that metropolitan flights could arrive to different locations, e.g. JFK, La Guardia and Newark in the New York area; National and Dulles in the Washington D.C. area. The concept of the traditional airport is obsolete and needs to be completely rethought, not modified. / Master of Architecture
