Utbredning av markvibrationer och stomljud från järnväg : Undersökning och anpassning av beräkningsmodell
The problems with train-induced vibrations are increasing with heavier and faster trains. Therefore the work with propagating vibrations is of outmost importance, and that is what this thesis relates to.To get a sensible idea of the propagation, calculation models are often used. Propagation calculation models takes into account factors such as distance to the railway, the ground material and the velocity and weight of the train. This work is mainly about finding suitable existing models and, if necessary, adjust them to be more useful with modern trains and railways.The report contains the work of adjusting one such model and does, despite the fully functional adjusted model, describe how much more there can be done within this topic. Finally, a few tips about specific areas that preferably should be studied to get even further knowledge about the troublesome problems from railways..

Internetbaserade distansutbildningar
In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.

Va' vad det vi sa... : Representationer av sharia i Europaparlamentet och dess möjliga konsekvenser för EU:s mångfaldstänkande, enhetspolitik och muslimsk identitet i Europa
Muslims and islam are unquestionably a part of European social life. In recent times, however, different events, such as the enlargement of the EU and the fact that muslims to a higher extent demand their rights, have brought a number of questions to the fore concerning muslims and islam in Europe. Moreover, we can see an increasing level of islamophobia in contemporary Europe, but also that the EU has launched several programs to increase both the diversity and the unity throughout the Union and to combat islamophobia. However, most of these programs focus on islam as religion and muslims in general, and such a narrow viewpoint runs the risk of missing important issues.In this new context it would be interesting to widen the scope and ask what place not only the muslim community and islam, but also sharia (an important element in islam), may have in future Europe ? especially when it comes to muslim identity?My main objects are to see how the concept of sharia is constructed in the debates in the European Parliament, how that discourse relates to a social practice ? the increasing islamophobic ideas in Europe ? and what effect this may have on muslim identity in a European context.The results shows that the Parliament constructs sharia as, for example, something archaic, threatening, inhuman and misogynistic.

Valet är ditt - Konsumentbeslut baserade på sekventiell produktinformation
Research has shown that our numbers of choices are constantly increasing. In this paper, we investigate the choice-making process further with regard to satisfaction, recommendation propensity, confidence, and preference. The study focuses on two fitness clubs where product information is provided sequential to the participant. We examine if consumers who maintain their choice tend to be more satisfied with their choice and more willing to recommend the choice to a friend. If they are, why is this? We found that the participants who changed their choice claimed to be less satisfied and had less propensity to recommend the choice to a friend.

Bära eller brista - byte av noteringslista? : Nya resultat från svenska aktiemarknaden
Denna eventstudie syftar till att undersöka hur ett byte av noteringslista påverkar kumulativ onormal avkastning (CAR) 1 till och med 12 månader efter genomfört byte. I studien undersöks därför utförda byten av noteringsplats på den svenska aktiemarknaden under tidsperioden 1995-2009. I studien beräknas onormal avkastning delvis med marknadsmodellen (MM) som grund, men också med Fama & French tre-faktormodell (FF) för att öka reliabiliteten. Vidare undersöks om skillnader i CAR föreligger under olika tidsintervall samt om olikheter förekommer efter att berörda företag delats in i undergrupper baserade på typ av byte, industri samt storlek. Slutligen testas utifall den eventuella kumulativa onormala avkastningen är signifikant skild från noll med student t-test samt om det föreligger skillnader i medelvärde i de olika undergrupperna.

By this said we have also taken into account the different laws and adjustments in the long-term sickness benefit, but also major reformation of the security net in the Swedish society. The efficiency of the law on passive long-term sickness absence was added in July 2008, but was later in January 2010 supplemented. The purpose of this law wasn?t only to reduce the long-term sickness absence but also to reduce exclusion.
Betavärdet som riskestimat
As stocks have become a more common way for people to save their money, the range of financial information has had a substantial increase. To understand the assumptions that stock valuation and analysis are built upon, it is important for the reader to have an understanding for the models that are used by banks and institutions when recommendations are published.The cash flow model, which is the most commonly used stock valuation tool, is based on CAPM. This model describes the relationship between an assets return and its risk in relation to an index. The risk parameter is called the beta value and has grown to be the dominating risk factor within financial economics literature.The use of beta values has been widely discussed in the world of academics and some researchers claim that the degree of explanation brought about by the beta is so low that it should be discarded, others are faithful to the beta and believe that it still serves a purpose. As a result of this criticism other ways to calculate the beta have surfaced, models that take other factors of risk into consideration.
