Frizon för ungdomar? ? En studie av ett ungdomsrum på folkbibliotek
This Master?s thesis concerns the question why a public library establishes a special room for young people and how the young people can influence the activities. I have made interviews with two librarians and four teenagers from a reference group. I have also made an observation of the room. The most important theories are Pierre Bourdieu?stheory of symbolic capital and Mats Lieberg?s theory of free zones.
Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework
This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
Umeå, de stora företagens kommun? : En studie om hur företagen i Umeå upplever kvaliteten på kommunens service

Sammanlagt medverkade 56 personer i studien, 32 killar och 24 tjejer i åldrarna 10-18. En grupp lågstadiebarn och en grupp gymnasieungdomar testades i VT, EPT, SPT och SEPT betingningar.
Motviktsslungans dynamik : En analys av medeltida konstruktionsråd för mekaniskt artilleri
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.

Att uppleva rum - ett utforskande projekt om rumslig gestaltning
This project in an in depth exploration about the basics of creating space in the form of an experimental investigation using my own perceptions as reference. Within a method, especially outlined for the project using descriptive words of opposites, my interpretation of the words has been formed into models of rooms. Four workshops with restrictions and rules acted as a platform for the striving towards the aim of a wider understanding of how space can be experienced. Through analysis I have formulated the different parameters influencing space itself and my perceptions of it. During the project a language for visualizing the interpretations of a room has been further evolved.

Farmers´ decisions factors : a case study
This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.
Två nya trailerkoncept för transport av rundvirke hos Stora Enso : en analys av prestation och flexibilitet
The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods.
In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

Equity Premium Puzzle : teori och empiri
Syftet med uppsatsen är att diskutera det så kallade equity premium puzzle. Jaganalyserar teoretiskt den intertemporala konsumtionsbaserade CAPM (C-CAPM),sammanställer en del av litteraturdiskussionen som finns på området samt empiriskttestar C-CAPM på svensk data. Fenomenet equity premium puzzle innebär attöveravkastningen på aktier är så stor att det inte stämmer med den ekonomiska teorin.Enligt teorin beror C-CAPMs riskpremie på kovariansen mellan konsumtionen ochaktieavkastningen. Litteraturen visar att forskare inte har lyckats förklara equitypremium puzzle genom att ändra antagandena i grundmodellen. Den empiriskaundersökningen visar att equity premium puzzle även uppkommer på svensk data..
Framtagande av ställbar krok för hängränna
The purpose of this project was to design an adjustable gutter bracket for Lindab Profil AB. Lindab currently manufacture a gutter bracket that is adjustable in angle, however, this model has some drawbacks. One of it´s shortcomings is that it is somewhat difficult for the customer to mount. Another problem with Lindab?s current model is that the design makes manufacturing unnecessarily complex. The new gutter bracket, that we have constructed, does not have these problems. It is adjustable for different roof pitches.

För att installera flera operativsystem samtidigt finns det olika verktyg avsedda för att underlätta denna process. Det finns både kommersiella- och gratisalternativ ute på marknaden. En av de ledande kommersiella replikeringsmjukvarorna är Symantec Ghost. I detta arbete jämförs Symantec Ghosts mot Free open-source ghost (FOG) för att mäta användbarheten med avseende på kritiska attribut. Kritiska attribut är baserade på utförandet av en fullständig replikeringsprocess samt hur en användare upplever hanteringen av mjukvaran.
Företagsvärdering i praktiken : Hur bör en säljare agera vid företagsöverlåtelse?
It is important to understand the process of appraisal of a business in order to establish its value. The purpose of our thesis is to establish which methods and models are used when evaluating a business and investigate the factors that may affect the value and price tag of a business. We have used a qualitative approach by conducting both indepth interviews and a survey as well as reading literature within the field. The main conslusion in our findings is that the common practice of discounted cash flow is widely used when bestowing a monetary value for a business, and in order to raise the value a well established customer relationship was the single most important factor. As far as lowering the value, the answers were of such a wide spread that a single factor could not be attributed.
