With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

After the last is age there was a long period when there was no shortage of forest for peoples needs. People living in Sweden could use the forest resources at their will. Around 4000 years BC the inhabitants of southern Sweden started to use the agricultural system and people become more stationary. The farms were located together in groups and together they formed a social association, the village. Successively the population grew and in some areas the forest started to become a finite resource.

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems. In this paper focus is applied to the development process within developing applications for Enterprice Digital Assistants (EDA) and to what extent the end-users are involved in the process. Fazer Bageri AB has been choosen to represent a business corporation that uses handheld computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

In this essay we discuss how the decentralisation of the Swedish school system affects the concept of ?equal opportunity school?. We investigate the development from both a historical and contemporary perspective, in order to identify changes over time. The central question of the essay is how the decentralisation of the school system affects the teacher?s perspective and experiences of the government?s framework about ?equal opportunity school?? The analysis is based on four qualitative, semi structured, direct interviews with respondents both active in municipal schools situated in the Malmö council and with more than thirty years of experience in their profession. Our analysis of the interviews show that both respondents experience the overall situation in the schools has deteriorated from an equal opportunity aspect since the decentralisation of the school system.

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

Background: outsourcing is one of the most obvious and continuous trends that has been able to study during the past ten years and also has had a strong development in the industry. What consequences will follow from an extended outsourcing? Purpose: the study?s overall purpose is to investigate what possibilities and risks that can be connected to an outsourcing decision and how the order of the service will handle the risks. The study will also investigate what management philosophy that will be used and regulate the outsourcing relation and how the company?s strategy will affect the decision and how the process of outsourcing will look like.

Will the discourse in a country effect the way an event is presented in the media? And will the event be presented in similar ways in different countries? These are the questions my paper aims to answer. By using critical discourse analysis I have analyzed the reporting of the Iraqi War in three big newspapers; one from USA, one from Sweden and one from Great Britain. The results show that the discourse in each country play a big part in how the news get presented in the media, and this is shown in how the news gets reported. The three countries had three different views on the same war.

In today?s society a large focus is put on energy systems and how our energy systems are built up. In order to make sure that we in the future still can enjoy the living standards that we are used to today, Sweden and EU have made a number of decisions on making our energy system more energy efficient and consequently reduce the usage of energy resources. By 2020 the European Union should have reduced its energy consumption by 20 % compared to 1990?s level, and by 2050, 50%.

The interest in providing a post 9/11 image of Islam to contrast the media?s frequent focus on its practitioners? alleged tendencies toward hostility and violence has in Sweden manifested itself (among other things) in an increased range of courses on Islam given by denominational Muslim organizations. In this paper I examine the construction of Islam by two Muslim organizations that offer education in Islam to non-Muslims in the context of the management?s stated goals of the education. My aim is to illustrate how discourses within these organizations are a result of the combination of local and global conditions..

IT exist and are needed in larger organisations today, this creates possibilities for new applications. It has become more frequent with IT within HRM which has developed new concepts like e-HRM and HRIS which links IT and HRM together. We have through qualitative content analysis of interviews investigated how IT-tools affect HR-workmanship. The purpose is to create a basis for describing how employees experience their work with HR within a PA-system. The basis of the PA-system will then answer if it contributes or limits the employees and their activities.

Den här uppsatsen undersöker lärarnas betydelse för musik- och kulturskolornas utbud och prioriteringar. Den undersöker också deras attityder inom olika områden som skulle kunna ha betydelse för dessa prioriteringar. Undersökningen är gjord enligt kvalitativ metod, genom intervjuer med instrumentallärare vid olika musik- och kulturskolor. Det är mycket som talar för att musiklärare uppfattar att de har ett stort inflytande över beslut som fattas inom musik- och kulturskolan. För det första upplever lärare att musikskolan själv har ett stort inflytande över sin verksamhet och att kollegiet bör vara en viktig grund för de beslut som tas.

AbstractTurkey has emerged as a major actor in the Middle East over the last decade, since the ruling party AKP came to power in 2002. Turkey is now playing a mediation role in regional conflicts and has been speaking out loudly on sensitive issues such as the Iranian nuclear program and the Palestinian- Israeli conflict. Furthermore, Turkey has established close ties with the Arab world which has suffered the relationship with its long-time ally Israel. This new presence in Middle East has been criticized by Turkey's allies in west. Critics argue that the country is about to abandon its former western relationship and strengthen their ties with the Arab world instead.This thesis has two main purposes.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Systemutvecklingsmetoder har funnits för att utveckla system ochprogramvaror sedan vattenfallsmodellen gjorde sin introduktion på dentiden då IT kallades för data processning. Sedan dess har det funnits ettantal metoder, vissa av dem används än idag. Gemensamt för de flestametoderna är att de är anpassade till mycket komplexa system som användsinom stora organisationer. Inom det Svenska samhället så fanns det år 2005över 890 000 småföretag (0-49 anställda) enligt statistiska centralbyrån.Det är lätt att förstå att småföretagen är viktiga för Sverige. För att Sverigessmåföretag skall kunna överleva i en allt tuffare konkurrenssituation så ärdet viktigt att de hela tiden effektiviserar sina verksamhetsprocesser medexempelvis innovativa IT lösningar.

Internet and digital technology has changed the way we live our lives. As individuals we've found new ways to communicate, educate and experience. But what's the effect on B2B marketing? Previous research presents transactional benefits such as lower costs and easier access to information, but there is limited research done on more complex and long term relationships as well as on modern digital tools. The purpose of this thesis is to investigate whether a deeper long term B2B relationship can be created and nurtured using digital tools for communication, and if so, how these tools and processes can be described and understood.
