This diploma thesis analyzes the operation of a small airport. It focuses on the status of this airport, on its history, infrastructure, air traffic control and services offered. There is also a comparison of small and large airport.

Global warming is an issue that affects the entire world. The aviation industry accounts for around three percent of global emissions, and actions are needed to help steer the industry towards a sustainable transition with new technologies and alternative aviation fuels to reduce emissions. There are options today for passengers to compensate flight emissions through carbon offsetting. The purpose of this report is to investigate how the aviation and carbon offset industries are likely to develop in the future in order to provide knowledge that an air travel comparison site can use to adapt its carbon offset alternative to new market conditions. The empirical data in this study consist of interviews with stakeholders in the aviation and carbon offset industries as well as a politician. Industrial reports and a literature review were used in combination with the empirical data and analyzed with theories such as industrial dynamics, network innovation and scenario analysis to result in a possible future scenario of the industries. Further, conclusions with necessary actions in order to develop a more sustainable aviation industry and how carbon offsetting can be renewed due to a sustainable aviation transition. Additionally, managerial implications for an air travel comparison site followed with suggestions on how they can contribute to this transition. The conclusions from this study are to develop existing networks and establish new ones to share knowledge from many different stakeholders in the industry and use their capabilities to propose regulatory changes as well as prepare the industry for sustainable solutions in the future. Networks should also use their collective power to lobby for changes that will drive the transition towards a more sustainable aviation industry forward. The broad expertise that these networks possess can be used to provide customers with knowledge to make the option to carbon offset a flight more attractive. It is important that knowledge and marketing of carbon offsetting is transparent to inform customers of its effects on the climate. Biofuels and electrified aircrafts are sustainable solutions more suitable for the future due to the high price of biofuels and electrified aircrafts not ready to replace regular jet-aircrafts. Thus, carbon offsetting is the best option to reduce net emissions from a flight today. The short-term recommendations are for an air travel comparison site to be involved in the transition towards more sustainable aviation fuel by offering customers the option to purchase biofuel together with or as an alternative to carbon offset when booking a flight. An air travel comparison should also support organizations and firms working with sustainable solutions such as introduction of electrified aircrafts, through partnerships or investments to help steer the industry in a sustainable direction. The long-term recommendation for an air travel comparison site is to continuously stay updated with the latest research and knowledge expertise within the industry to adapt its carbon offset alternative to new conditions in the future. This study is to be considered as an informational foundation for an air travel comparison site to adapt its carbon offset alternative to a dynamic aviation industry. However, the study does not include empirical data from all stakeholders within the aviation industry hence the information used in this study is limited. / Global uppvärmning är ett aktuellt problem som påverkar hela världen. Flygindustrin står för runt tre procent av de globala utsläppen och åtgärder behövs för att styra industrin mot en hållbar utveckling med ny teknologi och alternativa flygbränsle för att minska utsläppen. Idag finns det möjlighet för passagerare att kompensera sina flygutsläpp genom klimatkompensation. Syftet med denna studie är att undersöka hur flyg- samt klimatkompensationsindustrin troligtvis kommer att utvecklas i framtiden och hur företag inom flygindustrin kan tillämpa den kunskapen för att påverka utvecklingen mot en mer hållbar flygindustri. Med hjälp av kunskapen ska klimatkompensationsalternativ kunna anpassas utefter dem nya förutsättningarna i framtiden. Den empiriska data för denna studie består av intervjuer med intressenter från flyg- och klimatkompensationsbranscherna samt en politiker. Industrirapporter och en litteraturrecension har använts i kombination med empiriska data tillsammans med teorier såsom industriell dynamik, nätverksinnovation och scenario analys som resulterat i ett troligt framtidsscenario för industrierna. Vidare följer en slutsats samt ledningsliga implikationer och rekommendationer för en flygprisjämförelsesajt. Slutsatserna från denna studie är att utveckla redan befintliga samt etablera nya nätverk för att dela kunskap från många olika intressenter inom flygindustrin och använda sig av deras förmågor för att föreslå ändringar i lagstiftningen samt förbereda flygindustrin för hållbara lösningar i framtiden. Nätverk bör också använda deras samlade makt till att lobba för beslut som driver utvecklingen av en mer hållbar flygindustri framåt. Den breda expertisen som dessa nätverk besitter kan användas för att informera och förse kunder med kunskap om fördelarna med klimatkompensation och öka intresset för att klimatkompensera en flygresa. Marknadsföring och information om klimatkompensation behöver vara transparent för att kunder ska förstå effekterna det har på klimatet. Biobränslen och elektrifierade flyg är hållbara lösningar som är mer troliga för framtiden då priset på biobränslen är väldigt högt idag och elektrifierade flyg är långt ifrån redo att ersätta dagens jet-flyg. Därmed är klimatkompensation det bästa alternativet för att reducera nettoutsläpp idag. Kortsiktiga rekommendationer för en prisjämförelsesite är att vara involverande i övergången till mer hållbara bränslen genom att erbjuda kunder ett alternativ till att köpa biobränsle i kombination med att klimatkompensera. För att styra industrin i en mer hållbar riktning bör en flygprisjämförelsesite ge stöd i form av investeringar och samarbeten med organisationer och företag som arbetar med hållbara framtidslösningar som exempelvis utveckling av elektriska flygplan. Långsiktiga lösningar är att kontinuerligt hålla sig uppdaterade med den senaste forskningen och kunskapsexpertisen inom industrin för att anpassa sitt klimatkompensationsalternativ i framtiden. Denna studie ska betraktas som en informell grund för företag inom flygindustrin att påverka en övergång till en mer hållbar flygindustri samt utveckla sitt klimatkompensationsalternativ i framtiden. Studien innehåller ej empiriska data från alla intressenter inom flygbranschen och skall därför ses som begränsad.

The competence to establish and collect this tax was given to the States and the Federal District by article 155, item III, of the 1988 Federal Constitution of Brazil. The methodology conceived by the Logical and Semantic Constructivism was used to study the theme. According to said methodology, the Law is taken as a cultural object expressed in language and based on the categories of the Philosophy of Language. Initially, the object is submitted to an analytical analysis and following it is reconstructed with emphasis on the syntactic, semantic and pragmatic aspects of the terms. The work starts with some brief considerations on the legal rule and the source rule for the tax levy. Following, the work focuses on the historical aspects involving the IPVA and the possible requirement for the prior enactment of a nationwide supplementary law providing for the elements of the source rule for this tax levy enabling the competent political entities to establish it. This work also addresses the constitutional principles applicable to the IPVA. Finally, the source rule for the IPVA levy is constructed through a detailed analysis of all its constituent criteria / O trabalho constrói a regra matriz de incidência do Imposto sobre a Propriedade de Veículos Automotores IPVA , cuja competência para instituição e cobrança foi outorgada aos Estados e ao Distrito Federal pelo artigo 155, inciso III, da Constituição Federal do Brasil de 1988. Para o estudo do tema foi utilizada a metodologia idealizada pelo Construtivismo Lógico-Semântico, que toma o Direito positivo como objeto cultural expresso em linguagem e que parte de categorias da Filosofia da Linguagem para, inicialmente, realizar uma análise analítica do objeto, para em seguida reconstruí-lo, dando-se ênfase aos aspectos sintático, semântico e pragmático dos termos. O trabalho inicia-se com breves considerações a respeito da norma jurídica e da regra matriz de incidência tributária. Em seguida, foram examinados os aspectos históricos envolvendo o IPVA e a eventual necessidade da prévia edição de lei complementar nacional dispondo sobre elementos da regra matriz de incidência deste imposto para que as pessoas políticas competentes possam instituí-lo. Foram estudados, também, os princípios constitucionais aplicáveis ao IPVA. Por fim, é construída a regra matriz de incidência do IPVA, com o desenvolvimento de todos os seus critérios constitutivos

Through continued innovation and growth, traveling wave tube amplifiers (TWTAs) remains the microwave power amplifiers of choice in a wide range of high power microwave and millimeter-wave applications specifically for aerospace applications with the volume, weight, bandwidth and power constraints. These advances can be credited to device innovation, improved modeling and design and development of advanced materials and construction techniques. This thesis aims at advancing the present technology of TWTs with coupled resonator slow-wave structures (SWSs) by a combination of device innovation, development of enhanced analytical and field analysis codes and understanding gained through improved modeling, simulation and experimentation. In a TWT, the SWS that slows the RF wave velocity down to near the electron beam velocity for interaction with the electron beam primarily determines the microwave performances of the tube. As compared to helix SWS, the coupled resonator SWS is capable of handling high peak and average powers with higher efficiency and TWTs based on these SWS are well suited for air-borne or space-borne radar systems and the major focus of this thesis is on the analysis and design of coupled resonator SWSs. As a part of this thesis, improved analytical codes based on quasi-TEM analysis and equivalent circuit analysis have been developed. The technical formulation is explained and the improvements made for enhanced accuracy and for incorporation of different types of coupled resonator SWSs detailed. Using these models new variants of coupled resonator SWSs have been investigated. The SWSs proposed are the ladder-core inverted slot mode SWS and the inductively loaded inter digital SWS (ILID-SWS). The possibility of achieving both coalesced mode design that gives wide bandwidth and multi beam design that improves the peak power and gain using rectangular ILID-SWS is presented. The properties of these proposed SWSs have been compared with the existing SWSs and found to give superior performance. Also an improved modeling and simulation technique using 3-D electromagnetic codes has been proposed and the conventional cold test measurement procedure has been modified for more accurate results. Numerous illustrative examples are presented throughout the thesis highlighting the analytical model and simulation code validation with experimental results. The experimentations have been carried out on the real SWS model that have been fabricated and assembled. Further, the contribution of the thesis is towards the development of a field analysis model for analysis of a corrugated waveguide SWS, based on the coupled integral equation technique (CIET), which is a combination of mode matching technique (MMT) and method of moments. The technical formulation and computational methodology employed in the model are explained and some of the most important aspects of implementation like the handling of singularities and choice of parameters controlling the accuracy is discussed. The accuracy and speed of the code is demonstrated by comparing CIET with MMT and 3-D electro magnetic simulators based on finite difference time domain (FDTD) method and finite element method (FEM). The CIET code developed is quite faster than the existing numerical methods and helps in solving the convergence problem associated with the MMT.

The thesis analyses the legality of the use of drones in warfare based on the examination of three specific case studies. Firstly the use of armed drones in Afghanistan 2001 and 2002, then Pakistan drone strikes ongoing since 2004 and lastly the Yemen case study. A developed legal framework is used to assess the legality of the use of drones. Furthermore, it briefly touches upon the aspects of morality and ethics of the use of the unmanned aerial vehicles in combat.

The final master´s thesis targets to create concept study of VFR airport.This airport should be build up in southeast part of Czech republic, in the vicinity of the town Valašské Klobouky. In this work there are explained essential terms and definitions refered to basic rules and law. There are explained also civil aviation law and requirements of L14 regulations. Aeroclub is submitter of this work. It establishes basic conditions for airport area searching. The length of the runway is influenced mainly by performance of used aircrafts. It was impossible to find any acceptable field in searched area. There is a posibility how to solve this problem. There can be build up a runway for take-off and landings of small aeroplanes. In the second part of this thesis there are defined basic requirements on these fields. These requirements are applicated on chosen field. At the end of this thesis there is propounded an option how to dislocate runway, taxiways, aprons, hangars and other buildings.

Contrairement aux autres biens meubles, les navires, les aéronefs et les objets spatiaux affectés à la navigation internationale sont rattachés à un Etat. Le lien de droit public établi entre ces engins et l’Etat est communément appelé « nationalité ». Mais ce terme n’exprime pas à leur propos une institution à tous égards identique à la nationalité des personnes. Le rattachement examiné ne repose en effet pas sur des éléments de fait (naissance, ascendance etc.), mais uniquement sur un acte administratif interne, l’immatriculation. L’étude de la pratique, notamment des conventions internationales et des législations nationales, montre clairement que – contrairement à ce qu’on soutient souvent – il n’y a pas lieu de subordonner ce rattachement à un lien effectif. Ce qui importe, compte tenu notamment du fait que ces engins évoluent dans des espaces soustraits à toute compétence territoriale, est d’identifier l’Etat qui est seul compétent à l’égard de l’« ensemble organisé » formé par le véhicule, les personnes et la cargaison à bord, et qui est responsable de ses activités. Le droit international interdit dès lors la double immatriculation, mais il laisse aux Etats le pouvoir discrétionnaire de déterminer les conditions d’attribution de leur « nationalité », sans subordonner l’opposabilité internationale de celle-ci à quelque autre exigence que ce soit. Le danger est toutefois que cela favorise un certain laxisme de l’Etat d’immatriculation, ce qui exposerait au risque que des dommages graves soient causés aux personnes impliquées dans les activités de ces engins et – surtout – aux tiers. Mais ce sont les obligations internationales imposées et les droits corrélatifs reconnus dans le chef de l’Etat d’immatriculation qui sont déterminants à cet égard et non quelque mystérieuse « effectivité » du rattachement. Autrement dit, s’il n’est pas nécessaire d’imposer à l’Etat d’immatriculation des conditions internationales limitant sa liberté dans l’attribution de sa « nationalité » aux engins, il est indispensable d’exiger que celui-ci respecte ses obligations, c’est-à-dire exerce effectivement son contrôle et sa juridiction. Cette constatation se vérifie quel que soit l’engin en cause. Le rattachement créé par l’immatriculation constitue donc une institution "sui generis", commune aux navires, aéronefs et objets spatiaux et dont le régime juridique est encadré par le droit international. / Unlike any other movable property, ships, aircraft and space objects that are engaged in international navigation are linked to a State. The legal connection established between these craft/vessels and the State is commonly referred to as “nationality”. However, in this case the term does not represent an institution identical in all respects to the nationality of persons. With regard to vessels, the legal connection to a State is not based on factual elements (such as birth, descent etc.), but merely on the internal administrative act of registration. The study of State practice, notably international conventions and national laws, clearly shows that – contrary to what is often argued – there is no need to make this connection dependent on a pre-existing effective link. What matters most, given that these craft navigate in international space beyond the territorial jurisdiction of sovereign States, is to identify the State that holds sole jurisdiction over said “organized entity” consisting of the vehicle, the persons and the cargo on board and that is responsible for its activities. Public international law therefore prohibits dual registration, but leaves States free to determine the conditions under which they will confer their “nationality”, without imposing any other requirement for the opposability of this legal bond to third States. The danger is that this situation encourages laxity on the part of the States of registry and therefore creates the potential for serious damage incurred by persons involved in these vessels’ activities and – mostly – by third persons. In this regard, it is the international obligations and corresponding rights of the States of registry which are critical, and not a mysterious “effectiveness” of the legal bond. In other words, it is not necessary to impose on the State of registry any international conditions which would limit its freedom with regard to the conferral of its “nationality” upon vessels. It is however indispensable to require that said State complies with its obligations, meaning that it has to effectively exercise its jurisdiction and control over those craft. This statement holds true regardless of the craft concerned. The legal bond created by the registration therefore constitutes a "sui generis" institution, common to ships, aircraft and space objects, and whose legal regime is governed by international law.
