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 overall aim with this study is to elucidate outdoor education as an education method and on the basis of that illustration to examine active educators vision on it as a way to motivate students' learning. This study is based on a literature component and a qualitative study through interviews five teachers.The results of the interviews show how to interpret the motivation and how to work with students' motivation. As well as outdoor education as part of the activity.  The interviews show the importance of outdoor education can be to increase students'motivation for learning. They also show the importance of outdoor education is for student learning and test scores have shown the effectiveness of student learning through outdoor education.

This study demonstrates how norms and ideals about sexuality and gender expression are used in the TV-show The Walking Dead. An intermediate study is made on the comic books? two same sex couples as they are compared to how they are represented in the TV-show. Tara Chambler and Alisha, a same sex couple who only exist in the TV-show, not in the comic books, are also analysed. Queer theory and an intersectional perspective are used to discover how different power asymmetries are connected to each other through an active interplay.

Prostitution has for a long time been an understudied field in economics. Due in part to a lack of quantitative and empirical material, itself largely a result of the illegality or semi-illegality of the activity in most countries, the factors that explain the prevalence of, and pricing in, prostitution have remained largely undiscussed. In the last 20 year, this have begun to change: new theories ? notably by Edlund & Korn (2002), Rao et al (2003) and Della Giusta et al (2009) ? have been formulated and the rise of internet based escort sites have made large scale quantitative studies possible. This thesis examines if, and in what way, court documents can help expand the understanding of the economics of prostitution in Sweden.

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.

Denna studie undersöker om, och i så fall hur, utvecklingen av webbapplikationer med ASP kan förbättras genom tillämpning av COM-objekt. För att göra detta används fyra jämförelsekriterier som tagits fram utifrån fördelar och nackdelar med ASP respektive COM-objekt. Dessa kriterier avser att jämföra ASP och COM-objekt i exekveringstid av scriptkod, återanvändning av funktionalitet, inkapsling av databasrelaterad kod och prototyputveckling. Det resultat som erhållits av genomförandet visar att utvecklingen av webbapplikationer med ASP kan i olika situationer tillämpa COM-objekt för att: förbättra exekveringstiden av scriptkod, förenkla återanvändningen av funktionalitet och göra ASP-koden mer strukturerad genom att kapsla in databasrelaterad kod. Vad gäller prototyputveckling anses dock ASP vara bättre anpassat, då COM-objekt kräver noggrann planering av gränssnittet och dessutom är beroende av ett testprogram för att kunna testa prototypen..

This study's main objective was to identify adolescents participation in alternative sport activities and which kind of physical activity that was preferred by adolescents who didn't had any earlier experience of sport clubs.

The results showed that adolescents already physical active were those who participated in alternative sport activities. Who participate in alternative sport activities can depend on habitus, comprehended capital forms and in which social field the sport activities exists..

Efficient numerical methods for option pricing is an active field of research. This project has the goal to examine possible ways to improve an established method of numerical pricing. The method is based on an adaptive finite difference method in price and uses the backwards differentiation formula of order 2, BDF2, in time. The project will focus on improvements to the time integration through implementation of discontinuous Galerkin methods, dG. Empirical convergence and accuracy results are obtained for equidistant dG-methods up to order 3 and performance is compared to BDF2.

The purpose of this essay is to contribute to an extensive understanding of former criminals and addicts.

The purpose of this study is to present populism as a political phenomenon and to impose focus on the rightwing populist parties that are active in Scandinavia. This essay begins with a presentation of the three rightwing political parties in Scandinavia. The rightwing populist parties have successfully developed their rhetoric and effectively influenced the political establishment in Sweden, Norway and Denmark. The parties that the essay focuses on are theSwedish democrats (SD), the Norwegian Progress party (FRP) and the Danish People`s party (DF). These parties are interesting in the sense that they share many opinions and are active in comparable political atmospheres, but also that they use approximately the same rightwing populist rhetoric as a way of exerting leverage on political policy.The theoretical segment is constructed on a descriptive historical background of populisms three different phases.

This study analyzes how the Swedish climate policy has changed during the years 1990-2008. Thisis done through a comparative analysis of three climate bills that were developed during this period.With a constructivist approach, and theories about discursive indicators and discursive fields,discursive changes in the bills' content are identified. The results show that changes have occurredin how the problem is described, how the issue is framed, which problem solutions that areadvocated, which legitimizing arguments and key concepts that are used and the extent of theknowledge that the bills are based upon. The conclusions drawn from the results describe adiscursive change between the bills in the form of a shift from a discourse that in a greater extentadvocates active policy responses, based on ethical arguments about fairness towards othercountries and caution towards the environment, to a discourse that more often favor market actionsbased on arguments about the economic viability of Sweden..

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

This case-study examines the correlation between young men and democratic instability in group discussions with two analyzing methods in one. One part of the method used is deliberative democracy which aims to explain how democracy works within the frames of discussion in ordinary citizens groups. In this study the citizens is upper level secondary school students. The other part of the method used is the theory pulled by many scholars lately, the demographic impact on democracy. With these two combined in one this study compare the theory of young men as more active in political violence and as a destabilising factor of democracy on country-level with the results of the study in deliberative democracy in small group discussions.
