The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

In 1998 a new regional development policy was introduced by the Swedish government. A central feature in the policy was the formation of partnerships at the regional level. The partnerships were meant to consist of local and regional stakeholders, representing a great variety of interests, who would collaborate in order to improve regional development. The new policy was promoted, besides being more efficient, as a way to broaden political participation and to break male-dominated structures.This thesis discusses whether the regional partnership actually favours ?women's interests?, in terms of how the relationship of power between women and men is constituted by the model.

This comparative linguistic textstudy focuses on the relationship between a newspapers own outspoken political standpoint and it´s ambition of being an unbiased provider of objective information. This connection becomes particulary interestering in times of election when a newspapers role as provider of information is of great importance for the citizens. When a newspaper reports an event to the public, the reporter always has to choose from a small selection of possible linguistic forms when representing the story. Through linguistic analysis of these forms we can see that the final choice is often not a complete arbitrary one. We compared two daily newspapers, Dagens Nyheter and Dala-Demokraten, that stod on opposite sides in the Swedish EMU-elections 2003.

I föreliggande studie undersöks hur användare upplever användbarheten i ett säkerhetskritiskt system ? Luftfartsverkets flygledningssystem SIGMA. Utifrån litteraturstudier definieras begreppen användbarhet och säkerhetskritiska system. Empirin utgörs av intervjuer med användare av SIGMA-systemet. Studien visade att användarna upplever att systemet i väsentliga delar har bra användbarhet, vilket utifrån litteraturstudier, intervjuer och efterföljande analys främst tycks bero på att systemet arbetats fram med stor användarmedverkan och att det var utarbetat specifikt för arbetsplatsen.

The legitimacy of the European Union is being questioned, and this has put focus on the democratic deficit, as the main reason for the negative outcome of the referendum about implementing the last initiated treaties of the union. In this essay the credibility of the problem solving strategy through the communication policy of the commission is being put under the scope. The objective is to treat the credibility of the solution to the main problems of the EU as an important part of how the democratic, political system works and how it deals with taking care of its? supporting and demanding channels of communication. The importance of a citizen platform to form common interests and a strictly European dialogue using media, common debates and several other possible ways to advocate this solution throughout the whole union is stressed here..

Youth unemployement in Sweden is at an all-time high, a fifth of all university and college students live in poverty and the number of young on welfare is increasing. This study attempts to answer the question of how youth deprivation has been made possible as a consequence of political action, focusing on youth unemployment. I critically examine the role of the Swedish government, the Swedish Labour Organisation (LO), and the various government departments through text analysis, in order to answer the question of how the current discourse on youth position in the labor market. Because youth unemployment is not an isolated phenomena the analysis covers several policy areas, such as education policy, labor market regulation and housing policy. I use discourse theories drawn from Laclau and Mouffe to expose how language is used as an instrument of political power. I conclude that the current situation is a result of policy choices where the young have fallen behind due to lack of political organization. Their situation is not problematized to the required degree and is often explained on an individual level rather than on a structural level. .

AbstractIn the literature on multiculturalism and group rights there is a strong tradition that sees diversity as something directly paradoxal to unity. In this tradition, scholars put forward a view of multiculturalism as a divisive and exclusionary process which breaks down the cohesion and unity of society. Related to this notion is that of a neutral and universally valid frame of reference in which political dilemmas can be solved; for example a neutral civil sphere where the ?true essence? of society lies. In this essay I attempt to criticise these two notions.

Denna uppsats är ett resonerande argument kring massmedias roll i det demokratiska samhället.Vi diskuterar inledningsvis ett antal demokratiideal generellt, med syftet att ur dessa kunna identifiera ett gemensamt karaktärsdrag: att demokrati kräver politiskt medborgerligt engagemang. Detta karaktärsdrag används sedermera för att fälla ett normativt påstående kring massmedias roll och innehåll. Detta normativa påstående appliceras slutligen på tre stycken skilda demokratiska ideal med utgångspunkt i en specifik massmedial innehållstyp, personcentrering..

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Elever ska enligt kursplanerna i teknik få förståelse för de tekniska system de möter i sitt dagliga liv. Genom att eleverna får kunskap om teknik i allmänhet och tekniska system i synnerhet får de möjlighet att påverka sina liv som medborgare i en demokrati. I litteraturen saknas idag studier om elevers uppfattningar om tekniska system. Syftet med detta examensarbete är därför att studera vilka vardagsuppfattningar elever har om de tekniska system de möter i vardagen. Studien utgår från systemteori vilken ger en möjlighet att utnyttja det gemensamma mönster som kännetecknar analys av system.

This paper aims at describing and explaining the bi-and multilateral negotiations that are, and have been, taking place between Sweden's chief negotiator Allan Larsson and European countries, and within the EU institutions in Brussels, in order to seek support for the Swedish offer to host the European Spallation Source, ESS. It applies a case study method using political science theories ? governance and government ? and to a large extent information from the involved actors in the policy process. The paper also presents a constructive position, in showing how the negotiations on ESS can turn into a process leading to a decision on the construction of this research facility. ESS is negotiated in networks on bi- and multilateral levels consisting of European research representatives and financiers.

Citizenship is fundamental for participation in a democracy. It gives us rights but also responsibilities in the state that we are citizens of. Citizenship provides us with the opportunity to vote in order to influence who should govern us. However, not all living in a state are citizens. Some individuals are not included in the political life of the state.In recent years, there has been a rise of nationalist political parties in Europe.
