This master´s thesis deals with the delineating of nodal regions via civil aviation data in the territory of central European states. This kind of transport has become a very popular type of spatial mobility after its deregulation and liberalization particularly thanks to its speed, cheaper fares and relative safety. Thanks to this spatial mobility of inhabitants, it is possible to delineate borders of regions according to real movements. Supposing usage of aviation data to delineate nodal regions, the airports represent their nodes. The purpose of this master´s thesis was delineating nodal regions via civil transport data in an interesting territory of Central Europe. Its western and eastern part has undergone different historical and political development which has had consequences on the aviation development level. Research input data included number of flights between central European airports for the period of 1 day. The master´s thesis is structured into 5 chapters. The first parts are: introduction and goals, theoretical part and methodology. The analytical part evaluates the whole nodal-region-delineating process and also nodal regions final hierarchical structure. Each partial part of research was depicted into a map and was also expressed by population and area. There are answers on the input hypothesis in the final part of this paper.

Knowing the future water demand is essential for assessing investments destined to increase capacity and the potential benefit from adopting such measures. However, for such environments, there is a lack of studies on water consumption profiles, factors which affect water demand and forecast models. Thus the objectives of this study were to assess the influence of airport movement variables on water consumption and develop multiple regression models to predict it. The database was provided by Infraero and consisted of the annual number of passengers and flights, the annual amounts of cargo and mail, and the annual water consumption for the most important airports in Brazil. The models were developed considering airports grouped in terms of passenger capacity and category (domestic or international flights), and the performance was assessed by the determination (R2) and the Nash-Sutcliffe (NSE) coefficients. The model developed for airports with capacity to transport at least 10 million passengers a year were able to explain 81% of water consumption variation, whereas the model for airports with inferior capacity explained 62% of the variation. The models developed for international and domestic airports presented R2 of 90% and 89%, respectively. The NSE coefficients were 0.93 and 0.88 for the models considering capacity and category, respectively. The model developed specifically for the Airport of Confins-MG showed good performance (NSE = 0.98) and presented great potential to enable the inclusion of other variables that can reflect characteristics of each airport which are not considered by movement variables. / Aeroportos consomem grandes volumes de água e possuem grande potencial para a implementação de medidas de uso racional. Conhecer a demanda futura é essencial para avaliar investimentos destinados à ampliação de capacidade e o potencial benefício advindo da adoção dessas medidas. Para esses ambientes, no entanto, são poucos os estudos sobre o perfil de consumo de água, fatores que o influenciam e modelos para sua previsão. Portanto, os objetivos deste estudo foram avaliar a influência das variáveis de movimentação aeroportuária sobre o consumo de água e utilizá-las na obtenção de modelos de regressão linear múltipla para estimar este consumo. A base de dados disponibilizada pela Infraero contém informações sobre a movimentação anual de passageiros, voos, carga e mala postal, além do consumo anual de água para os principais aeroportos do Brasil. Os modelos foram desenvolvidos considerando a distinção dos aeroportos em termos de porte e categoria, e os coeficientes de determinação (R2) e de Nash-Sutcliffe (NSE) foram utilizados para avaliação do desempenho. Os modelos desenvolvidos considerando o porte apresentaram R² iguais a 0,81, para aeroportos de grande porte, e 0,62, para aeroportos de médio e pequeno porte. Para aeroportos que operam apenas voos domésticos, foi obtido um modelo linear simples com r² igual a 0,89; para aeroportos que operam voos internacionais e domésticos, o modelo apresentou R² igual a 0,90. Os coeficientes NSE foram 0,93 e 0,88 para os modelos considerando o porte e a categoria, respectivamente. O modelo desenvolvido especificamente para o Aeroporto de Confins-MG apresentou melhor desempenho (NSE = 0,98) e o potencial para viabilizar a inclusão de outras variáveis capazes de refletir características específicas de cada aeroporto não consideradas pelas variáveis de movimentação.

Diante destas circunstâncias, o presente trabalho tem como objetivo identificar as possíveis causas das ocorrências dos defeitos parabólicos observados na superfície dos pavimentos flexíveis das pistas de pouso e decolagem e de taxiamento do Aeroporto Internacional de Natal. Para isso, realizou-se uma avaliação estrutural não destrutiva, por meio do levantamento deflectométrico com o Falling Weight Deflectometer (FWD), o qual foi realizado em toda a extensão das pistas e em diversas faixas de aquisição de dados. Com o FWD obteve-se as bacias de deflexões que possibilitaram por processo de retroanálise, por meio do software BAKFAA 2.0, caracterizar o comportamento resiliente in situ das camadas do pavimento. Com o software ELSYM5 realizou-se a análise empírico-mecanística, para verificar os níveis de tensões cisalhantes atuantes nas diversas profundidades das camadas do pavimento, inclusive na interface de ligação entre as camadas asfálticas. Também foram realizados ensaios laboratoriais de caracterização das propriedades mecânicas, tais como: módulo de resiliência, resistência a tração indireta e o ensaio de Leutner shear Test. Concluiu-se que os defeitos observados na superfície das pistas enquadravam-se na série de defeitos classificados de escorregamento do revestimento asfáltico, ou Slippage, e que os fatores que culminaram na ocorrência destes defeitos relacionam-se com a baixa aderência da interface de ligação e com a incompatibilidade de rigidez entre as camadas adjacentes de mistura asfálticas. / In order to remedy pavement degradation, evaluation studies of the structural conditions should be carried out to identify the possible causes of the defects and, above all, provide information on which corrective measures should be taken to restore adequat and acceptable conditions of the pavement. In view of these circumstances, the present work has the objective of identifying the possible causes of parabolic defects seen in the surface of the flexible pavements of the landing and take - off runways and taxiways of Natal International Airport runway. For this, a non-destructive structural evaluation was carried out by means of the deflectometric survey with the Falling Weight Deflectometer (FWD), which was carried out along the whole length of the tracks and in several ranges of data acquisition. With the FWD, the deflection basins were obtained, which enabled the BAKFAA 2.0 software to characterize the in situ resilient behavior of the pavement layers by means of a retro-analysis process. With the ELSYM5 software, the empirical-mechanistic analysis was performed to verify the levels of shear stresses at different depths of the pavement layers, including the interface between the asphalt layers. Furthermore, laboratory characterization of mechanical properties such as: resilience modulus, tensile strength and Leutner shear test were carried out. It is concluded that the defects observed on the runway surface fit into the series of defects classified as slippage of the asphalt coating, or Slippage, and that the factors that culminated in the occurrence of these defects are related to the low adhesion of the interface and With the incompatibility of stiffness between the adjacent layers of asphalt mixtures.

Estes contratempos podem acarretar prejuízos vultosos para as empresas envolvidas e desconforto ao usuário da aeronavegação. Por isso, este estudo teve como objetivo a determinação de padrões atmosféricos que originam a ocorrência de condições meteorológicas adversas no Aeroporto Internacional de Belém (SBBE), através da aplicação da análise fatorial (AF) em análises de componentes principais (ACP). Foram usados os dados meteorológicos de superfície do SBBE e de Radiação de Onda Longa (ROL), em ponto de grade sobre Belém, proveniente das reanálises do National Centers for Environmental Prediction (NCEP). Através dos indicadores estatísticos, foi selecionado o conjunto de variáveis adequadas para a aplicação daACP. Os dados utilizados foram dos períodos chuvosos de 2003 a 2012, pois na estação chuvosa foi detectado o maior número de emissões de mensagens especiais (código SPECI) no SBBE. O fator dominante está associado à variação diária do aquecimento/resfriamento da superfície. O segundo fator representa as alterações no teor de umidade próximo da superfície, decorrente da variabilidade climática associada com anomalias da temperatura da superfície do mar nos Oceanos Atlântico e Pacífico. E o outro fator igualmente importante, tem relação com a presença de convecção profunda, e consequentemente, de tempestades, as quais foram desenvolvidas por mecanismos das circulações locaisdinâmicos em mesoescala, tais como circulações de brisa marítima e/ou fluvial sobre a área em que se localiza o SBBE. Este último fator foi o qual apresentou o maior número de ocorrência das variáveis que apresentam relação com o estabelecimento das situações meteorológicas adversas que limitam as operações de pousos e decolagens no SBBE. / The occurrence of adverse weather conditions at airports determines unfavorable situations to air traffic, as visibility and ceiling restriction, and slippery track conditions, which are a major risk factor for safety operations. These setbacks can cause sizeable losses for the companies involved and discomfort to the airworthiness of the users. Therefore, this study aimed at determining weather patterns that cause the occurrence of adverse weather conditions in Belem International Airport (SBBE) through the application of factor analysis (FA) on principal components analysis (PCA). It wasused meteorological surface data from the SBBE and outgoing longwave radiation (OLR), in grid point over Belém (Brazil), from the reanalysis of the National Centers for Environmental Prediction (NCEP). Through statistical indicators, it was selected the appropriate set of variables for the application of the PCA. The data used were in the rainy periods of 2003 to 2012, as the rainy season has been detected as many reports of the SPECI code in the SBBE. The dominant factor is associated with the daily variation of the heating/cooling of the surface. The second factor is the changes in the moisture content near the surface as a result of climate variability associated with temperature anomalies of the sea surface in the Atlantic and Pacific Oceans. And another equally important factor is related to the presence of deep convection, and consequently storms, which were developed by mechanisms of dynamic local mesoscale circulations such as circulations of maritime and/or fluvial breeze over the area in which is located the SBBE. This last factor was the one which had the highest number of occurrences of the variables that have relation with the establishment of the adverse weather conditions that limit of takeoffs and landings operations in the SBBE.

Com o aumento do tráfego aéreo no aeroporto de Ribeirão Preto - SP e o conhecimento de várias reclamações sobre o incômodo sonoro junto ao Ministério Público é apresentada uma análise, através de simulação computacional, de como ficou as curvas de ruído deste aeródromo. O objetivo deste estudo foi verificar como a população, que está no seu entorno, é afetada pela operação das aeronaves e qual o percentual a ser encontrado após a simulação realizada com o programa INM (Integrated Noise Model). A simulação indicou que o aumento das operações no Aeroporto Leite Lopes SBRP não ocasionou um impacto maior na população afetada dentro da área definida pela curva de 65 dB(A), ficando este valor dentro de parâmetros aceitáveis pelas normas adotadas. A velocidade e a direção dos ventos locais contribuem para o aumento do impacto ambiental, sugerindo a necessidade de alterar as rotas das aeronaves conforme ocorrerem estas mudanças meteorológicas. O estudo indicou a necessidade de alteração das rotas de pouso e decolagem. Orientar os pilotos através dos controladores de voo que pousos e decolagens sejam efetuados pela cabeceira da pista 36 (trinta e seis), prolongando o eixo de decolagem em mais 2 milhas náuticas ou 2 km. Para mitigar o efeito do impacto produzido pelas operações das aeronaves no aeroporto, se faz necessário a realização de novos estudos para que possamos orientar o planejamento urbano do entorno utilizando novas rotas de voos com novos levantamentos de campo e simulações. / With increasing air traffic at the airport of Ribeirão Preto - SP and the knowledge of numerous complaints about noise nuisance with the Public Ministry, it is presented an analysis through computer simulation of how would be the noise curves of this airfield. The objective of this study was to determine how the population, which is in its surroundings, is affected by the operation of aircraft and what percentage to be found after the simulation performed with the program INM (Integrated Noise Model).The simulation indicated that the increase in operations in Leite Lopes Airport - SBRP did not cause increases in the affected population within the area defined by the curve 65 dB(A), with this value within acceptable parameters by the standards adopted. The speed and direction of local winds contribute to the increased environmental impact, suggesting the need to change the routes of aircraft as these weather changes occur. The study indicated the need for change in takeoff and landing routes. Guide the pilots through the flight controllers that takeoffs and landings are made by the end of the runway 36 (thirty six), extending the shaft off at over 2 nautical miles or 2 km. To mitigate the effect of the impact produced by aircraft operations at the airport, it is necessary to carry out further research so we can guide the planning of urban environment using new flight routes with new field surveys and simulations.

Since the beginning of the 20th century, airports equipments were transformed and evolved into different proportions, specially after jet times, in order to optimise the flow, reducing the walking distances for passengers: from terminals to planes. The terminals were rebuilt and extended to adapt to changes and expansion of commercial flight and airplane dimensions; redesigned by architects and following the engineering technical improvements, terminals have come through innovations, which typological classification is one of the main themes of this research. The other subjects developed are: a historical panorama of the international architecture of airports, the birth of Brazilian architecture in this field, and an emphasis on the study of the typologies of some of the most important terminals of Europe, United States and Asia. A sequence of case studies, accompanied by several images composing an iconographic dossier, synthesizes into a classification of contemporary projects of terminal building types, analysing its possibilities of extension. / Terminais de passageiros em aeroportos representam uma das obras mais significativas da atualidade arquitetônica, constituindo um campo de experimentações tecnológicas e formais que se desdobra em uma série de tipologias. A partir do início do século passado, as estruturas aeroportuárias transformaram-se e evoluíram em diferentes proporções, notadamente na era dos jatos, a fim de otimizar o fluxo de passageiros: dos edifícios aos aviões. Os terminais foram redesenhados, reformulados ou ampliados para atender ao constante aumento e às mudanças do tráfego aéreo, bem como ao porte das aeronaves; esculpido nos projetos dos arquitetos e executado pela lógica e a técnica dos engenheiros, o terminal tem passado por inovações, cuja classificação tipológica é um dos principais temas desta dissertação. Um panorama histórico do cenário internacional, elementos dos primórdios da arquitetura aeroportuária no Brasil e ênfase no estudo das tipologias dos grandes terminais da Europa, Estados Unidos e Ásia, constituem as demais partes do trabalho. Uma seqüência de exemplos, apoiados em vasto dossiê iconográfico permite identificar as tipologias paradigmáticas de projetos contemporâneos e suas possibilidades de ampliação.

Nas últimas décadas, o rápido avanço do setor aeroportuário nacional decorrente do crescimento econômico e populacionais expos os gargalos de infraestrutura e da malha aeroviária brasileira ficando os aeroportos limitados a polos habitacionais mais estruturados. O aumento do fluxo de passageiros transportados no setor aéreo neste período tem compelido o planejamento e construção no setor público para a ampliação dos terminais aeroportuários de passageiros denominados no meio aeronáutico como TPS. A observação do impacto e interação entre as decisões do projeto arquitetônico, quantidade e dinâmica das informações, normas e legislação nacional e internacional, que estão constantemente sendo atualizadas e desbalanceadas, geram fatores determinantes no processo projetual e construtivo. A motivação na elaboração desta tese é preencher uma lacuna quanto a escassez de estudos no Brasil que enfoquem especificamente o processo de projeto arquitetônico nos TPS. Para realizar a pesquisa foi utilizado o método Design Science Research (DSR), visando auxiliar projetistas de arquitetura e coordenadores de projeto na gestão de projetos de terminais aeroportuários regionais de passageiros. O desenvolvimento da tese foi baseado na análise de terminais aeroportuários de passageiros domésticos e regionais brasileiros fruto da experiência do autor na área, na revisão bibliografia nacional e internacional deste tipo de edificação. Como resultado foi criado um termo de referência estruturado, para o planejamento do processo de projeto arquitetônico contemplando elementos para gestão de requisitos de programa, do fluxo de projeto, da coordenação e da compatibilização do projeto arquitetônico com os demais projetos específicos, legislações, normas, agentes, instituições, concessões e órgãos públicos fornecendo diretrizes básicas para o processo de projetos de TPS. / In the last decades, the rapid advancement of the national airport sector, due to the economic and population growth, exposed the infrastructure and the Brazilian air transportation route, making the airports limited to the housing poles with better structure. The increase in the transported passenger flow on the airline sector, in this moment, has compelled the planning and construction of the public sector for the expansion of the airport passenger terminals, named in the aeronautical environment as TPS. The observation of the impact and the interaction between the decisions of the architectural design, amount and dynamic of the informations, national and international rules and legislation, which are continually being updated and unbalanced, create determining factors in the design and constructive process. The motivation on the elaboration of this thesis is to fill the gap, regarding the scarcity of studies in Brazil which aim specifically the process of architectural design on the TPS. To make the research the Design Science Research (DSR) method was used, aiming to help architecture designers and design coordinators on the project management of regional airport passenger terminals. The thesis development has been based on the analysis of domestic and Brazilian regional airport passenger terminals, which is a result of the author expertise on the area, on the national and international literature review of this sort of building. A structured terms of reference was created as a result, for the planning of the process of architectural design contemplating elements for the management of program requirements, design flow, coordination and compatibility of the architectural design with the other specific designs, legislation, rules, agents, institutions, concessions, and public agencies, providing basic guidelines for the process of TPS design.

Per- and polyfluoroalkyl substances, PFASs, are highly fluorinated substances where the carbon chain is fully- or partly fluorinated. A functional group is coupled at the end of the carbon chain which gives PFASs their different properties. PFASs have been used in aqueous film forming foams (AFFFs) to decrease the surface tension of water and form a film on the fuel surfaces. AFFF is one of the main sources of PFASs pollution in the environment. A previous study has shown high PFASs concentrations in surface water in Lake Vänern. This study has analysed PFASs in sediment samples. The main detected PFASs was perfluorooctane sulfonate, PFOS, with concentrations below limit of detection to 51700 pg/g wet weight (ww). The compound detected in the highest concentration in Vissbäcken was PFOS at 7290 pg/g ww, this was followed by 6:2 fluorotelomersulfonate , 6:2FTS, at 516 pg/g ww. In outlet 4 (utlopp 4), PFOS had the highest concentration at 51800 pg/g ww, followed by perfluorohexane sulfonate, PFHxS, at 1790 pg/g ww. The only detected compound in the sediment cores was PFOS with approximately 100 pg/g ww. The high concentration of PFOS might be due to extensive use with subsequent release of firefighting foam in the area and degradation of other PFAS substances into PFOS. / Per-och polyfluoroalkylsubstanser, PFASs, är en grupp högfluorerade ämnen där kolkedjan är helt eller delvis fluorerad. En funktionell grupp kopplas i slutet av kolkedjan vilket ger PFASs dess olika egenskaper. PFAS har använts i vattenhaltiga filmbildande skum (AFFF) för att minska ytspänningen av vatten och bilda en film på bränsleytan. AFFF är en av huvudkällorna för PFAS-föroreningar i miljön. En tidigare studie har visat på höga koncentrationer av PFASs i ytvatten i Vänern. I denna studie har PFASs analyserats i sedimentprover. Den huvudsakliga detekterade PFAS var perfluoroktansulfonat, PFOS, med koncentrationer under detektionsgränsen och till 51700 pg /g våtvikt. Den högst detekterade föreningen i Vissbäcken var PFOS med 7290 pg/g våtvikt, detta följdes av 6:2 fluorotelomersulfonat, 6:2 FTS, med 516 pg/g våtvikt. Den högst detekterade föreningen i utlopp 4 var PFOS med 51800 pg/g våtvikt, följt av perfluorhexansulfonat, PFHxS, med 1790 pg /g våtvikt. Den enda detekterade föreningen i sedimentpropparna var PFOS med ungefär 100 pg/g våtvikt. Förekomsten av PFOS i sediment i sjön Vänern kan bero på omfattande användning med efterföljande utsläpp av brandbekämpningsskum i området och nedbrytning av andra PFAS-substanser till PFOS.

In this thesis I focus on Emirates Airlines, in particular by identifying key factors that led to the acquisition of the current position in the global aviation market. Till the foundation of Emirates Airlines the aviation industry in this region practically did not exist, and therefore it was not too interesting market in general. Using the research of case study at the thesis, I first examined how and why the airline was founded and subsequently described the uniqueness of this particular case. Partial aims are to answer the research questions and confirm or refute the initial hypothesis. In conclusion, I summarized all the key factors and assess their uniqueness and potential limitations when applied to similar cases in the aviation sector.

La croissance du trafic aérien a rendu critique l’opération de la gestion des plateformes aéroportuaires. Celle-ci fait appel à de nombreux acteurs (autorités aéroportuaires, compagnies aériennes, contrôle du trafic aérien, prestataires de services, …). Le concept d’Airport Collaborative Decision Making (A-CDM) développé depuis une dizaine d’années est basé sur un partage d’informations opérationnelles en temps réel entre les différents acteurs de la plate-forme, permettant de prendre des décisions en commun pour rechercher une utilisation optimale, en toutes conditions, des capacités de l’aéroport. L’objectif principal de cette thèse est de contribuer à l’organisation de la gestion des opérations d’escale dans une plateforme aéroportuaire. Il s’agit de proposer une structure d’organisation de cette opération qui soit compatible avec l’approche A-CDM. La structure proposée introduit un coordinateur des opérations d’escale (GHC) qui joue le rôle d’interface de communication entre les partenaires de l’A-CDM et les différents gestionnaires des opérations d’escale (GHM). Cette structure hiérarchique permet d’une part de partager des informations avec les partenaires de l’A-CDM et d’autre part d’interagir avec les gestionnaires des opérations d’escale (GHM). Les processus de prise de décision basés sur des heuristiques ont été développés à chaque niveau de l’organisation proposée et sont évalués aussi bien dans le cas de conditions nominales que dans le cas de la présence de perturbations majeures. / The increase of the world air traffic growth of the last decades has generated a permanent challenge for civil aviation authorities, airlines and airports to supply sufficient capacity to provide a safe transportation service with acceptable quality standards. New traffic management practices, such as A-CDM, based on multi-agent and collaborative decision making concepts have been introduced at airports. However, within the turnaround process of aircraft at airports, ground handling management of aircraft has not been developed specifically in the A-CDM approach, even if it has an important role in the fluidity of aircraft operations at airports. The main objective of this thesis dissertation is to contribute to the organisation of the ground handling management at airports. It consists to provide a structure organize the ground handling management compatible with the A -CDM concept. The proposed structure introduces a ground handling coordinator (GHC) which is considered as an interface for communication between the partners of the A -CDM and the different ground handling managers (GHM). This hierarchical structure allows sharing information with partners in the A -CDM on the one side and on the other side, interacting with ground handling managers (GHM). Decision making processes based on heuristics have been developed at each level of the proposed organization and have been also evaluated in the case of nominal conditions and in the case of the presence of major disruptions.
