AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.

Syftet med denna studie är att belysa ungdomars tankar kring sina framtida levnadsvillkor.Genom en kvalitativ ansats intervjuades ungdomar kring frågor om vidare studier, arbete, ekonomi och huruvida de ville flytta hemifrån. Urvalsgruppen bestod av 8 ungdomar av båda könen. En avgränsning var att ungdomarna skulle gå årskurs 3 på gymnasiet.Studiens resultat visade att ungdomarna kunde tänka sig att ta det arbete som erbjuds om de inte hade möjlighet att välja. Om de hade ett val, kunde ingen av ungdomarna i studien tänka sig att gå arbetslös och ta emot ekonomiskt bistånd i stället för att arbeta. På sikt tyckte de dock att det var viktigt att ha ett meningsfullt arbete som de trivs med och tycker är kul.Ungdomarna tyckte att det var viktigt att få en bra utbildning då detta är avgörande för hur man klarar sig i framtiden.

The purpose of this study is to analyze how university students, who are not members of a political party, experiencing existing selective and collective incentives for involvement in a political party. Furthermore, the study will highlight incentives which could help the political parties to increase their membership. The study is based on seven interviews and the respondents were selected after conducting a survey of students? political involvement. The interviews were analyzed through the theory of selective and collective incentives. The study shows that the incentives, both selective and collective, for involvement in a political party in general are weak and that the costs in terms of time, money and education are seen as too high.

The research work performed in this thesis has been carried out at the Production Tech-nology Centre where the Thermal Spray research group of University West has its work-shop and labs.This research work has been performed in collaboration with the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad, India.First of all, I would like to express my sincere thanks and gratitude to my supervisors Dr. Nicolaie Markocsan and Dr. Nicholas Curry for their guidance, great support and valuable suggestions without which this work could not have been possible. I would also like to thanks Prof. Per Nylén for keeping faith in me and providing me an opportunity to work at PTC, which is a great place to perform research.

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

Since the mid 60?s, Germany has seen dropping fertility rates and yet next to nothinghas been done to combat this trend until the current regime led by Angela Merkel andher minister of family affairs, Ursula von der Leyen initiated a number ofcomprehensive reforms of Germany?s family policies.Family policy in Germany is being reformed in three ways. First of all parents arenow eligible to receive substantial financial support in order to compensate the loss ofincome associated with a pregnancy and or parental leave. Second, the all but nonexistentpublic child care services are being vastly expanded with the goal of beingable to offer child care service for every child age 0-3. Thirdly the tradition of schoolsending classes midday is being reformed with the aim of letting kids stay in schoolmuch longer thus enabling parents to work full-time as opposed to part-time in orderto be able to take care of kids returning from school.The hopes for these ambitious reforms are tremendous.

This master thesis is an attempt to study the joint-use solutions between the public library and the public preschool in the local district Kristineberg in the community of Borås. The two main questions are; what kind of joint-use library is the activity at Kristineberg? What kind of advantages and disadvantages do the actors experience from the joint-use activity at Kristineberg? The analysis is based upon the interviews with eight informants with different connections to the joint-use library and public preschool. I also use documental analysis and literature studies. Relevant theories, such as Andersson´s and Skot-Hansen´s analysis of the role of the public library and Bundys, Imhoff´s and Dornseif´s theories about joint-use libraries are presented and later used in the analysis.

The purpose of this master thesis is to examine different factors that may influence the librarian in the selection of popular music. The study is conducted through a qualitative method, influenced by grounded theory. The results are based on patterns drawn from both interviews with six libraries and from literature. The literature review concerns foremost cultural politics, music aesthetics, the sphere of popular music in Sweden today and the impact of commercialism. Also the purposes of popular music in a library, aspects of values of popular music and assortment policies are being discussed.

Bakgrund: Ett sätt att minska risker vid handel med finansiella instrument är att bygga portföljer. För att kunna hantera portföljer med olika finansiella instrument och valutor samt kunna hantera flera portföljer samtidigt, används portföljhanteringssystem. Studenter kan genom att använda sig av sådana system lära sig hur finansiella marknader fungerar. Kraven på ett portföljhanteringssystem är inte desamma som kraven på ett kommersiellt system och därför finns det ett behov att utveckla en modell för denna kontext.Syfte: Denna uppsats ämnar bygga en modell i PowerPlus Pro som studenter kan använda sig av för att befästa sina kunskaper och öka sin förståelse för hur finansiella instrument fungerar.Metod: För att bygga modellen har kvalitativ metod används och för att studera hur portföljhanteringssystem ska byggas och anpassas efter studenters behov har kvalitativa intervjuer använts.Slutsatser: Vår modell uppfyller de krav som ställts på den och är anpassad för undervisning på ett universitet genom att den är användarvänlig och pedagogiskt uppbyggd. Modellen lämpar sig inte för användning av markadsaktörer.     .

The development of technology and the mechanization in the Swedish forestry has during the last 60 years resulted in depopulation of the country side and due to that the amount of distance forest owners has increased. Therefore the forest companies need to make some adjustments in order to keep the distance forest owners as customers and to attract new ones. The purpose of this essay was to examine and analyze the distance forest owners satisfaction with Södras service offering and quality of service and further develop some proposals for action. A web-based survey was sent out to 634 distance forests owners in Stockholm, Sweden, all members of Södra. 269 respondents participated in the survey and of them, 27 did also participate in a follow-up telephone interview.

The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
