Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

Minnen i marknadsföring: Nostalgia in advertising, communication effects, relationships and critical periods for establishing emotional bonds to collective events

Many perceive a boom in nostalgia and what is retro, especially within the marketing discipline. This thesis studies how nostalgia functions in the advertising context and aims to shed light on which effects there are from nostalgia evoking communication, what connections there are with other important factors as well as aspires to develop the understanding of the underlying psychological aspects and the emotional bonds to events (as nostalgia evoking stimuli in the thesis), which pave the ground for nostalgic emotions. Point of origin has been classical measures of communication effects and models of connections and causality and to these important factors have been added. Results show clear connections and correlations between nostalgia and positive communication effects, even with control for other factors that may interfere. However, the results show that some factors have moderating effects that should be important to take into consideration, namely how well the brand and the event in the ad are perceived to fit the advertising context.

Lycka och livskvalitet ? Vägen till välbefinnande : En studie om den subjektiva upplevelsen av psykiskt välbefinnande

The main purpose of this study was to examine how people who have felt mentally bad, describe their subjective experience of what leads to a mental well-being. The overall research questions were; how does the individual define mental well-being, how does the individual describe the turning-point during her tough period, and in what way does the individual consider that her own effort has influenced her well-being? In order to answer these questions, qualitative research interviews were conducted with persons who?ve felt mentally bad and who?ve got some kind of professional help, and who think that they have a mental well-being today. The empirical material was analyzed from a theoretical resilience perspective. The study?s result showed first of all, that there are different ways to define well-being.

Är hållbar utveckling ute på djupt vatten?

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

E-handel : Vilka faktorer styr konsumentens köp över Internet och då med fokus på hälsokostbranschen?

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

När religion och djurskydd kolliderar : slakt utan bedövning

The fact that animals have feelings is something that is commonly agreed. Many authors showhow animals' views of their environment is quite similar with human views. Animals, whichare slaughtered without prior stunning, find the moment of slaughter unpleasant and stressing.This is shown in numerous of scientific studies. The cognitive ability of animals can becompared to how they experience feelings and scientists have shown how the structures in thebrain that involves feelings and cognitive behaviours in animals are very much the same asthe structures in human brains. Because of this, some scientists consider that behaviour inanimals can be directly interpreted into human feelings.Halal- and kosher slaughter comes from traditions.

The Value of Digital Information DIV-index, A Corporate Asset

Companies have in the past decades changed fromtraditional manufacturing organizations into serviceorganizations. For these service organizationsinformation and competence have become animportant resource. The traditional view oninformation is that an employee use and search forinformation to reduce uncertainty for their decisionmaking. Even though information is strategicallyimportant for organizations, information is not valuedin any way. Hence, this thesis aims to valueinformation in terms of the utility it brings to theorganization.The conclusion is that four factors are important whenvaluing information in terms of utility.

Social ekonomi: Staten och det civila samhällets betydelse utifrån ett rättighetsperspektiv

The increasing significance of social economy as a concept is linked to general global processes such as the crisis of the welfare state, neoliberal globalization, anti-bureaucracy tendencies and decentralization, but also to a growing political interest in human rights and social development. In Sweden the idea of the social economy generates wide support within civil society as well as within the government and across party political boundaries. Furthermore, what is problematic in this context is the fact that the discussions on the subject tend to be relatively uncritical and often it seems as if though the expansion itself is the main objective. The emphasis on cooperation and the third sector in terms of welfare production implies a set of risks in relation to state responsibility, democracy and the autonomy of civil society. This paper aims to explore those risks and how they can be dealt with within the Swedish context..

Analysis of Intent Specification and SystemUpgrade Traceability

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

Thaksin Shinawatras Drogkrig över 2,000 mord och en jordskredsseger

Den 14de januari 2003 startade en av Thaksins mest häpnadsväckande populistiska kampanjer, vilket är ämnet för min uppsats.I ett tal till en stor samling befattningshavare deklarerade han att regeringen skulle genomföra en kampanj där alla droger i Thailand skulle elimineras på endast tre månader.De följande tre månaderna mördades över 2,200 människor, varav ett flertal enligt vittnen var helt oskyldiga, och merparten enligt Human rights watch (HRW) lättare droganvändare. Flera Människorättsorganisationer och kritiker misstänker att en stor del av dessa dödsfall var utomrättsliga avrättningar utförda av, eller på uppdrag av statlig polis. Trots skarp internationell kritik fortlöpte kampanjen utan större offentliga protester i Thailand.Thaksin annonserade i slutet av kampanjen drogkriget som en stor framgång. Han vann ett år senare sin andra jordskredsseger..

Biologisk behandling av oljeförorenad jord : Abiotiska faktorers inverkan och effekter av olika uppläggningssätt på nedbrytningshastigheten.

The purpose of this report was to investigate how the abiotic factors (temperature, pH, nutrients, oxygen levels and water content) would affect the decomposition of oil-contaminated soil and how a variance in structured soil would affect the decomposition-rate. A minor field-study was made and soil where structured in five different ways (one was a default pile and was used as a reference). The study took place over 137 days and three samples were taken (start, middle, end) and analyzed for aromatic and aliphatic compounds. The result of this study shows that there is a significant difference between all methods for the aliphatic compounds and no significant difference for the aromatic compounds. The abiotic factors that affect decomposition vary from organism to organism, depending on what type of environment it will function the best.
