Is GDP per capita one of the main drivers affecting demand for passenger air travelling? Based on the time series analysis conducted for North American and Middle Eastern region, we have not rejected hypothesis about positive impact of GDP per capita on demand for air travelling. The thesis also analyzes whether the effects observed are weaker for more developed and more saturated markets. The second hypothesis was rejected, as we have found that the effect of the GDP per capita was on average 10% stronger for the North American region than for the Middle Eastern region. Moreover, we have found that for both regions oil prices are the important driver of the passenger air travel demand.

General Nathan F. Twining distinguished himself in leading the American Fifteenth Air Force during the last full year of World War II in the European Theatre. Drawing on the leadership qualities he had already shown in combat in the Pacific Theatre, he was the only USAAF leader who commanded three separate air forces during World War II. His command of the Fifteenth Air Force gave him his biggest, longest lasting, and most challenging experience of the war, which would be the foundation for the reputation that eventually would win him appointment to the nation's highest military post as Chairman of the Joint Chiefs of Staff during the Cold War.

The diploma thesis deals with the design of air-conditioning equipment in the building of a multifunctional hall in Brno and also includes an experimental analysis of air flow. It consists of 3 parts. In the first part a theory of air distribution is elaborated. The second part deals with the analysis of air flow for different types of air diffusers and for one diffuser further looks for a simplified model. The last part of this work is focused on the design of air conditioning equipment in the assigned building, the multifunctional sports hall.

As alternative fuels are becoming more common, technologies need to adjust to them. Natural gas is one of the alternative fuels that has grown during the latest years in the transport sector. Natural gas consists of around 97 % methane and is the cleanest fossil fuel. The use of natural gas can make it easier to transition to biogas as it has equivalent properties. Today Scania CV AB's trucks fuelled by natural gas are using auxiliary cabin heaters driven by diesel. This means that the natural gas trucks have two fuels on-board the truck. The goal of this project is to find a concept to eliminate the diesel fuel and replace it with an auxiliary cabin heater driven by another energy source. It will improve the heating solution and make it superior from an environmental perspective. The result of the project lead to a short-term solution with an auxiliary heater fuelled by natural gas. A long-term solution is to have a cooperation with a manufacturer to develop a better natural gas auxiliary heater that fulfils more of the requirements in the technical specification. An experiment plan is devised to test parameters out of reach of the project.

This diploma thesis is dedicated to the European Commission's project known under the name Single European Sky which pursues an objective to reorganize the current European airspace structure for the more efficient provision of air navigation services purposes. As an introduction, the author sets himself the goal to acquaint the reader with relevant international organizations in the field of civil aviation, introduce him in a general way into the provision of air navigation services' issues, including the situations when these services are being provided across the national boundaries. Following this general reading, the thesis fluently moves on to its main subject matter which is the Single European Sky initiative. An attention is focused on the state of European airspace before the initiative has been launched as well as the preparatory works which resulted in the adoption of the first SES legislative package. The following chapter presents the basic legal framework regulating the Single European Sky as amended by the adoption of the second legislative package. Principal part of the thesis is comprised in the next chapter dealing with the process of project's implementation. Within its framework, the reader's attention is turned, inter alia, to such crucial issues as the national supervisory...

Aujourd'hui, la pompe à chaleur (PAC) est largement utilisée pour les applications de chauffage du bâtiment en raison de ses bonnes performances énergétiques. Elle est même considérée comme une source d'énergie renouvelable et, selon la Directive Européenne 2009/28/CE, la part «renouvelable» de l'énergie produite doit être calculée à partir de la performance annuelle. Il est donc important d'être à même de mesurer cette dernière. Or, il n'existe pas, pour les PAC air/air, de méthode fiable et simple permettant de mesurer la performance chez le client pendant une saison.Dans ce contexte, la thèse propose deux méthodes in situ qui répondent à ce besoin. La première est basée sur des mesures non-intrusives des propriétés du fluide frigorigène. Elle utilise le bilan énergétique du compresseur pour déterminer le débit du fluide. La deuxième, fondée sur les mesures côté air, utilise un ensemble de capteurs à fil chaud afin de mesurer le débit et les températures d'air.La thèse développe également une méthode de mesure intrusive du fluide frigorigène, qui n'est pas adaptée aux conditions in situ mais sert de référence pour valider les deux méthodes in situ. Les résultats expérimentaux montrent que la méthode de référence est précise non seulement en conditions stabilisées mais également en fonctionnement dynamique (y compris lors des dégivrages).La validation des deux méthodes in situ a été réalisée par une campagne d'essais spécifique en laboratoire. Une suite intéressante de la thèse consistera à intégrer la méthode non intrusive côté frigorigène directement dans l'équipement de mesure et d'affichage de la PAC. / Today, heat pumps (HP) are widely used as heating systems in building thanks to their high energy efficiency. They are even considered as a source of renewable energy and, according to the EU Directive 2009/28/EC, the amount of renewable energy has to be calculated from the annual performance. Therefore, it is important to be able to measure the annual performance. However, concerning the air-to-air HP there is no reliable and simple method which allows measuring the performance in situ during at least a season.In this context, the thesis proposes two in situ methods that could fill this gap. The first one is based on non-intrusive measurements on refrigerant side. It uses a compressor energy balance to determine the flow rate. The second one, based on air measurements, uses a distribution of hot-wire sensors to determine the air flow rate and temperatures.The thesis also develops an intrusive refrigerant method, which is not necessarily adapted for in situ conditions but can be used as a reference to validate the in situ methods. The experimental results show that the reference method is accurate both in stationary conditions and in dynamic operations (including during defrosting period).The validation of the in situ methods was performed by a specific test campaign in laboratory. As a perspective, the thesis makes it possible to develop on-board measurement methods using non-intrusive refrigerant sensors, providing an opportunity for manufacturers to display the in situ performance in real time.

The main content of this thesis is a design and an assessment of energy-saving measures with an objective of energy economical optimization of a particular family house. The theoretical part of the thesis describes problems of the energy performance of the building. The calculating part is devoted to economical and environmental assessment of two solving options with a use of a computer program which enables a monthly calculating measure. One part constitutes a design of air-conditioning systems, heating and drawing up an Energy Performance Certificates. The part of the thesis which is focused on a computer technology application deals with energy performance optimization with a use of a program which enables a daily calculating measure and making models of pictures of flowing with a use of CFD methods.

Third part describes design of two systems and possible testitng method. In last part, the real parametrs are put into the computing model followed by verification of the results and evaulation of the designed systems.

The Diploma thesis is divided into 2 parts. The first one deals with the description of CAN-bus and the protocol of SAE J1939. The second part contains the practical solution to controlling of Passenger Operated Doors and controlling of Air Sprinte (ECAS). Both parts refer to contemporary (conventions/standards) and the whole task is solved in a new program environment KIBES-32.
