<p>This is a Master Thesis at the Computer Science Program at Växjö University. It has been made at BSR in Växjö where the development of a diagnostic tool has been in the running since the beginning of 2008. Previously there was a base developed within the company which I was to use for developing the two layers that I was responsible for – ProtocolLayer and PresentationLayer. In the end it should lead to a XML-based diagnostic tool. The technologies used have been .NET with its language C# and XML. The future purpose for this tool is for it to be used within the company to receive important information about the cars when developing other BSR products.</p><p>This thesis has focused on developing the tool to be working with the car manufacturer VOLVO and its protocols. The idea is that the diagnostic tool in the future could be extended to be working with all possible car manufacturers’ protocols and to enlighten the extensibility the project has been done using the product-line approach.</p>

Nowadays, almost all existing wheelchairs have the problem that they only satisfy the disabled people to use for normal moving and transportation. A new wheelchair with a gear system guide rail which installed in the car is presented in this paper. The gear guide rail system will transport the whole wheelchair and person on it into the car. This wheelchair system will help people with disability whatever passengers or drivers to get into cars automatically. In this paper, the operation and the strength will be analysed through 3D model and theoretical calculations. Surveying to Swedish market, Volvo XC60 and V60 is chosen to design the size of the wheelchair. Besides, this new wheelchair system also can be suitable for the cars which are larger than those two car models.

The challenges facing low voltage grids are rising as an increasing number of domestic houses transition from fossil fueled heating to electricity based heating. Several environmental goals and visions have the same transition from fossil based power to electricity based power in mind for the transportation sector. One of the most important tools for this transformation is widely regarded to be the electric vehicle. With the demands of the electric vehicle pressuring the power grid, several questions arise regarding the growth of the electric vehicle market and what repercussions it may have on the grid. This paper focuses on a typical low voltage grid in southern Sweden and what effects a growing electric vehicle market may have on it. Through computer-assisted simulations based on several future scenarios regarding the EV market, this paper finds that few modifications and reinforcements are needed on this particular grid within the next 10 to 15 years. After this timeframe the voltage drop becomes a serious concern and should be addressed. / Utmaningarna som lågspänningsnät står inför växer i takt med att fler bostäder övergår från fossilbaserad till elbaserad värme. Flera miljösatsningar och visioner ämnar pådriva samma förändring inom transportsektorn och eldrivna fordon anses som ett av de viktigaste verktygen för att genomföra detta. Med ytterligare potentiella påfrestningar på lågspänningsnäten från de elektriska fordonens behov ställs frågan hur utbredd den elektriska fordonsmarknaden kommer att bli och vilken påverkan den kommer ha på elnäten. I detta arbete belyses ett typiskt lågspänningsnät i södra Sverige och vilka effekter elfordonens utbredning kan tänkas ha på den. Genom datorstödda simuleringar enligt flera olika prognosscenarion finner arbetet att relativt få förändringar och förstärkningar behöver göras på det analyserade nätområdet inom ett tidsspann på ca 10 till 15 år. Efter detta tidsspann orsaker lasterna ett högt spänningsfall i det aktuella nätet som bör åtgärdas.

This thesis describes the process of improving the engine oil cooler performance for future vehicle applications, from ideas to simulated concepts. Increasing market expectations of high engine power, low fuel consumption and high towing capabilities results in an ever rising pressure on the cooling system in modern cars. The desire to prevent a future situation where the engine oil could become too hot, formed the basis for this thesis. The thesis was performed during 10 weeks from March to June 2015, at Volvo Car Corporation in Gothenburg. The working process started with literary studies where the theory behind automotive cooling systems and heat exchangers were studied to increase the general knowledge about the theory. Studies of engine oil, heat transfer and the overall design of engine cooling systems were performed. An important part was to clarify why the oil must not exceed a certain temperature limit. This gave answers to how the oil and engine components would be affected, if the oil did exceed the set temperature limit. To get a clear target and measurable parameters, the goal of this thesis was defined by estimating what the heat transfer demands could be in the future. A competitor analysis was made to examine how and if, the competitors to VCC use a different kind of oil cooling. Generation of concept ideas were made continuously during the early stage of the work process. Concepts that proved to be interesting were analysed more deeply with performance simulations and packaging studies. Five concepts were analysed and the performance simulations indicated that all the presented concepts can reach the heat transfer goal set early in the process. They do however use different methods, and meet the goal with different levels of efficiency. All concepts are listed with their heat transfer performance results and their advantages and disadvantages. The concept that showed to be the most promising in an oil cooling perspective, was to connect an additional heat exchanger in series after the current plate heat exchanger. This is a solution which will support the current engine oil cooler by handling the additional heat produced during certain driving scenarios. The best concept reached a heat transfer rate of 40 kW at half the air flow required by the second best concept. The concepts that has been presented will implicate an alteration of the current oil cooling system design. The lack of available space in the cars will also result in some rearranging of components in order to make space for an additional heat exchanger. The purpose with the concept generation is to present a good foundation from which Volvo can base their future decisions on.

Three global trends are about to greatly influence the world we live in; collaborate consumption, a strong environmental awareness and a third industrial revolution that includes 3D printing, advanced robotics and open source software. This project is addressing these changes in order to evoke new enthusiasm for cars among the general public and again be a creative and positive driving force in our modern society. The proposal is illustrated through a halo car for a local car sharing fleet targeted at the Norwegian market. The car seeks to create immediate attention through dynamic design elements as well as long lasting enthusiasm through non-compromised usability.

Ο τίτλος της διπλωματικής είναι «Κατασκευή συστήματος αναγνώρισης κίνδυνου σύγκρουσης αυτοκίνητου με προπορευόμενο μέσω ψηφιακής επεξεργασίας video». Σκοπός ήταν η κατασκευή ενός συστήματος, το οποίο έχει την ικανότητα να διακρίνει τα αυτοκίνητα από όλα τα αλλά αντικείμενα που εντοπίζονται κατά τη διάρκεια μιας πορείας με αμάξι. Αυτό επετεύχθη με τη χρήση μεθόδων εξαγωγής χαρακτηριστικών, και συγκεκριμένα κυματίδια Haar και φίλτρα Gabor. Η ταξινόμηση έγινε με τη χρήση νευρωνικών δικτύων και μηχανές διανυσμάτων υποστήριξης (Support Vector Machines - SVM). / The subject of this diploma thesis is the manufacturing of a driver assistance system. Robust and reliable vehicle detection from images acquired by a moving vehicle (i.e., on road vehicle detection) is an important problem with applications to driver assistance systems and autonomous, self-guided vehicles. The focus of this diploma is on the issues of feature extraction and classification for rear-view vehicle detection. Specifically, by treating the problem of vehicle detection as a two-class classification problem, we have investigated several different feature extraction methods such as wavelets and Gabor filters. To evaluate the extracted features, we have experimented with two popular classifiers, neural networks and support vector machines (SVMs).

This research studies the relationship between car manufacturers (CM) and third party logistics providers (TPLP), also known as the logistics partnership, in the outbound delivery channel in the Malaysian automotive industry. It focuses specifically on the dyad perspective, and demonstrates that several critical success factors are required for a successful relationship between these two parties. Five such factors emanate from the operational dimension and eight from the relational dimension. The five operational factors are: logistics service performance, investment, information sharing, information technology and communication, and price of the logistics service; and the eight relational factors are: trust, commitment, power, conflict, dependency, co-operation, informal activity, and understanding. The study also reveals that five outcomes are identified that benefit both the CM and the TPLP as a result of the win-win situation accruing to both parties. These are: renewal of the contract, company profitability, improved logistics service performance, knowledge transfer, and company branding. Such benefits enhance the supply chain relationship, and knowledge of these advantages improves current TPLP theory by deepening the understanding of how logistics partnership can succeed. In order to obtain rich data concerning the CM-TPLP relationship, the researcher adopted a different methodology from that used by previous scholars, who have concentrated on quantitative techniques. In this study, multiple case studies (seven in total) in one industry, the automotive industry, in the non-western context of Malaysia, were conducted. Three main steps in the case study protocol were followed. The first involved a review of the literature pertaining to the themes that required further exploration, together with the development of the interview questions. In the second step, data were collected using semi-structured interviews, observations, document reviews, photographs and also archival records. Qualitative content analysis was used to analyse the qualitative data. The third stage involved exploring the data until it was found that nothing new was emerging from the interviews, and hence theoretical saturation had occurred. At this point the factors in question were confirmed, and the initial model revised. Additionally, confidentiality was maintained in all respects to protect the participating organisations and individuals. The findings contribute to the understanding of the CM-TPLP relationship which enhance supply chain relationship and TPLP theory, since they shed light on the operational and relational factors in one specific industry, from a dyadic perspective, and in a non-Western context, thereby adding new dimensions to the existing body of knowledge in this field. The findings benefit practitioners via the novel LPS (logistics partnership success) model generated by the researcher. This indicates the key contributory factors to the CM-TPLP relationship success. Moreover, the study may have the capacity to generalise to other culturally-similar environments.

Der Automobilsektor ist derzeit einer der wichtigsten Industriezweige in Europa. Ca. 2,2 Millionen Mitarbeiter sind direkt, weitere 9,8 Millionen indirekt darin beschäftigt (sechs Prozent aller Beschäftigten in Europa) und erwirtschaften mit einem Umsatz von ca. € 780 Milliarden im Jahr einen bedeutenden Teil des europäischen Bruttoinlandprodukts (BIP). Auch aus Sicht der Konsumenten ist das Auto für 80 % der Europäischen Haushalte, die ein Auto besitzen, aus dem täglichen Leben nicht mehr weg zu denken. Die europäischen Staaten beziehen ca. € 380 Milliarden ihrer Steuereinnahmen aus der Automobilindustrie. Damit haben sowohl Staaten, Konsumenten als auch die Automobilindustrie ein gewichtiges Interesse am Florieren der Branche. Die Schattenseite der Automobilindustrie sind die CO2-Emissionen, die mit 20 % (der Anteil lag 1970 bei 12 %) aller CO2-Emissionen in Europa einen wesentlichen Teil zum Klimawandel beitragen, Tendenz steigend. So haben im Lauf der vergangenen Jahre mehr und mehr Staaten ihre Besteuerung der Pkw explizit oder implizit nach Umweltstandards ausgerichtet. Damit soll das Autofahren verteuert oder eingeschränkt und / oder die Nutzung von schadstoffarmen Pkw gefördert werden. Neben den Klimaschutz verfolgt die Europäische Union (EU) das Ziel, einen einheitlichen europäischen Binnenmarkt zu schaffen. Durch den Mangel an verbindlichen EU-Richtlinien im Bezug auf Abgaben, haben die Gesetze, Steuern und Abgaben auf einzelstaatlicher und regionaler Ebene ein kaum mehr zu überschauendes Maß angenommen, da Im Rahmen des Subsidiaritätsprinzips die Mitgliedsländer weiterhin ihr Steuersystem überwiegend autonom gestalten, sofern dies im Einklang mit bestimmten europaweiten Vorgaben steht. Dies führt zu einem sehr heterogenen Steuersystem, das gerade im Bereich des Verkehrs bedeutende Markteffekte (z. B. höhere Zulassungszahlen für Diesel betriebene Pkw oder kürzere Haltedauern) nach sich zieht. Europaweit einheitlich sind lediglich Regelungen zu Wettbewerbsbeschränkungen. Es lassen sich nach wie vor viele Beispiele für Marktverzerrungen und die Heterogenität der Steuersysteme in Europa finden: Marktverzerrungen und Wettbewerbsbeschränkungen zeigen sich bei Fahrzeugpreisen, die in Europa stark variieren. Beispielsweise kosten in Dänemark Pkw bis zu 37 % weniger als in Deutschland. Diese Arbeit untersucht und vergleicht die Abgaben auf den Erwerb, den Besitz und die Nutzung von Pkw in den EU-Ländern sowie Norwegen und der Schweiz sowohl systematisch als auch quantitativ. Zur quantitativen Analyse wurde eine Datenbank mit den zur Steuerberechnung notwendigen Informationen erstellt. Darunter sind beispielswiese: Steuersätze und –tarife, Fahrzeugdaten, Kraftstoffpreise, Instandhaltungskosten, Versicherungsbeitrage, Wechselkurse und der durchschnittliche Wertverlust der Fahrzeuge. Darauf und auf bestimmten Annahmen basierend wurden die absoluten Abgaben für repräsentative Fahrzeuge in den verschiedenen Ländern berechnet. Besonderes Augenmerk gilt der CO2-orientierten Besteuerung, die in 17 Ländern (zumindest teilweise) eingeführt wurde. Diese Arbeit betrachtet auch andere, d. h. nicht fiskalische Maßnahmen der Europäischen Union zur CO2-Reduzierung, vergleicht diese mit alternativen Instrumenten, und analysiert die Wirkung unterschiedlicher Besteuerung auf den Pkw-Binnenmarkt, z. B. den Einfluss von Abgaben auf die europäischen Automobilpreise und damit auf Arbitrageeffekte. Es zeigt sich, dass die Besteuerung in Europa sowohl in der Abgabenhöhe als auch konzeptionell in der Vielzahl der Bemessungsgrundlagen und Steuertarife sehr heterogen ist und maßgeblich zu den sehr unterschiedlichen Gesamtkosten der Pkw-Nutzung beiträgt. Die relative Abgabenlast ist in einkommensstarken Ländern Westeuropas nicht hoch genug, um den Kraftstoffverbrauch spürbar zu reduzieren. Aus dem gleichen Grund ist von der CO2-orientierten Novellierung der deutschen Kfz-Steuer kein ausreichender Kaufanreiz zugunsten effizienterer Fahrzeuge zu erwarten. Die in der Vergangenheit von der Europäischen Union eingeführten Instrumente zur Reduzierung von CO2-Emissionen aus dem Straßenverkehr führten nicht zu den erwünschten Emissionsverringerungen. Die jüngste Maßnahme der Europäischen Union, den Automobilherstellern Emissionsgrenzen vorzuschreiben, ist weder effektiv noch effizient. Im letzten Jahrzehnt haben sich die Automobilpreise in Europa zwar etwas angeglichen. Dies liegt weniger an einer Angleichung in der Besteuerung als an der schrittweisen Liberalisierung des europäischen Automobilmarktes und den Novellierungen der Gruppenfreistellungsverordnung. / The automotive industry is currently one of the most important industries in Europe. Approximately 2.2 million people are directly employed in this industry, and an additional 9.8 million jobs indirectly depend on it. This represents 6 percent of all jobs in Europe. A significant amount of Europe’s gross domestic product is generated in this sector which produces a turnover of approximately € 780 billion per year. Governments, consumers and car manufacturers have a significant interest in a flourish automotive industry: 80 % of all European households own a car and rely on it in their day to day life and the European member states are collecting approximately € 380 billion in tax revenue from the automotive industry. One of the problems caused by the automotive sector are the carbon dioxide (CO2) emissions and their impact on the environment. 20 % of all CO2 emissions in Europe are currently caused by cars, being a major contributor to climate change. The contribution has increased from 12% in 1970 and is expected to grow even further in the future. Consequently, several countries recently introduced taxes that consider carbon emissions with the aim to reduce the use of cars, or to incentivise the use of more fuel efficient vehicles. The automotive sector is not only relevant for the European Union’s (EU) climate policy, but for its broader goal to ensure a functioning internal market with free movement of people, goods, services, and capital. However, the degree to which a free internal market can be achieved also depends on the homogeneity of the tax system throughout the EU. To date, taxes and other duties are still very heterogeneous across the EU, due to the lack of binding regulations and directives with respect to taxes – in accordance with the principle of subsidiarity embedded in the Maastricht treaty. These differences affect the automotive sector, for example in terms of demand for diesel cars, or the average number of years that a car is used. More importantly, market distortions can still be observed in the automotive sector: Heterogeneous tax systems lead to vastly different car prices within the EU, e.g. cars are up to 37% cheaper in Denmark than in Germany. This study compares and analyses - both quantitatively and qualitatively - taxes and duties on cars in connection with their purchase and registration, ownership and tenure as well as use. The analysis covers all 27 EU member countries, Switzerland and Norway. For the quantitative analysis, a software based database and simulation tool was developed. This tool contains all relevant data, such as tax rates, tax scales, car characteristics, fuel prices, car maintenance costs or depreciation rates. The simulation tool uses the data to calculate taxes and duties for a number of specific cars models (selected representatively covering all segments) for each of the 29 countries, relying on certain assumptions where necessary. The analysis focuses particularly on taxes introduced to reduce the CO2 emission of cars in the EU, namely CO2 based taxes of motor vehicles, which have been introduced in 17 of the 29 countries. This thesis also considers other, non fiscal measures of the EU that are designed to reduce CO2 emis¬sions of cars. These measures are subsequently analysed and compared to other instruments in order to understand the impact of different taxation models on the European internal car market, for example, with respect to car prices in the EU and hence potential for arbitrage. The thesis demonstrates that material differences in taxation of cars exist, both regarding the total amount of taxes levied in similar circumstances, but also regarding the underlying concepts and bases for assessment. This heterogeneity results in vastly different costs of purchasing, owning and driving a car. In the relatively wealthy countries in Western Europe, costs are not sufficiently high to have a notable impact on the consumption of fuel. This is also why the new German tax on car ownership, although based on the average fuel consumption, is not expected to create a significant incentive for consumers to buy more fuel efficient cars. Similarly, the EU measures to reduce CO2 emissions of car usage failed to deliver the desired outcomes. The most recent instrument of the EU, prescribing emission thresholds for car manufacturers, is neither effective nor efficient. The thesis also shows that during the last ten years car prices in the countries of Europe have converged. However, this is less due to the increasing similarities in taxation, but instead due to the gradual liberalisation of the European car market and the renewal of the block exemption for the motor vehicle sector.

Water is known to take on highly organized structures to influence the reactivity of chemical and biological systems; despite this, water is often only implicitly or approximately included in theoretical studies of biochemical systems, if not omitted entirely. Many of the current models for biological processes predate an understanding of the complex behaviour of water, yet these models have not been updated. This thesis presents an exploration of how a better of water might affect the models used to describe neurotransmission. Two classes of systems are investigated, representing the two main categories of neurotransmission: that which occurs along the length of a neuron, and that which occurs between one neuron and another cell. Lipid bilayers are studied using molecular dynamics, and neurotransmitters are studied using Car-Parrinello molecular dynamics. The results indicate that water structures may play a more specific role in neurotransmission than was previously thought.

Driving can provide independent and efficient mobility. However, according to the driving license directive (91/439/EEC) are persons with locomotor impairments are only allowed drive if their disabilities can be compensated. Compensation can be realised by vehicle adaptations. The directive provides meagre guidance on how vehicles should be adapted or how to verify that the compensatory requirements are fulfilled. This is a gap in the current process for licensing drivers with physical disabilities. Furthermore, the Swedish process from driver assessment to driver licensing and adaptation approval is complex, fragmented, and suffer from lack of communication between involved authorities. The objective of this thesis was to contribute to the development of a method to evaluate vehicle adaptations for driver with physical disabilities. The focus was on the evaluation of adaptations for steering, accelerating and braking. Three driving simulator experiments and one manoeuvre test with adapted vehicles were conducted. A group of drivers with tetraplegia driving with hand controls were compared to able-bodied drivers in the first experiment. Even if the drivers with tetraplegia had a longer brake reaction time they performed comparable to the able-bodied drivers. However, they spent more effort and were more tired in order to perform as well as the able-bodied drivers. It was concluded that the adaptation was not sufficient. An Adaptive Cruise Controller (ACC) was tested in the second experiment in order to find out if it could alleviate the load on drivers using hand controls. It was found that the ACC decreased the workload on the drivers. However, ACC systems need to be adjustable and better integrated. The results from the first two experiments were used to provide some guidelines for ACCsystems to be used by drivers with disabilities. The third experiment was preceded by a manoeuvre test with joystick controlled cars. The test revealed some problems, which were attributed to time lags, control interference, and lack of feedback. Four joystick designs were tested with a group of drivers with tetraplegia in the third experiment. It was concluded that time lags should be made similar to what is found in standard cars. Lateral and longitudinal control should be separated. Active feedback can improve vehicle control but should be individually adjusted. The experiments revealed that drivers with the same diagnose can be functionally very diverse. Thus, an adaptation evaluation should be made individually. Furthermore, the evaluation should include a manoeuvre test. Finally, it was concluded that the evaluation approach applied in the experiments was relevant but needs to be further developed.
