Direct-EGR tillämpat på HCCI
The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.
Svensk bilindustri och utlandsägande : En studie av Volvo och dess underleverantörer
The purpose of this study is to explore the factors affecting an individual's working life mobility and how this mobility is perceived by the individual. The study has a qualitative approach and the theoretical part is based on Castells', Giddens' and Bauman's theories of modern society and employment in relation to the individual. The study concludes that external circumstances in combination with internal driving forces are the reasons behind changing careers. The process is predominantly perceived as positive, especially education tends to strengthen self-identity. Work in general is regarded as important for a person's identity and new career changes are expected in the future..
Bemästra, bistå eller både och? : En kritisk studie av Provincial Reconstruction Teams roll och agerande i Afghanistan
The specific task of this thesis is to illustrate the complexity of a cooperation between civilian and military entities by examining Provincial Reconstruction Teams (PRTs) and their role as an actor among others in the field in a war-torn Afghanistan.By using counterinsurgency strategy as an analytical framework it has been possible to examine the civilian and military contexts closer. Underlying structures concerning the norms and interpretation of reality of the PRTs has been partly revealed. Studies of the PRTs as one significant bearers of "the comprehensive approach", which includes a holistic approach regarding the use of civilian and military capabilities, new conclusions can be drawn on whether a general civil-military approach can be a part of the solution for current and future conflicts. Based on the counterinsurgency strategy, the author has identified three themes as bearing and thus appears through the thesis as a foundation. These are Coordination, Development and Security.

Den sportjournalistiska bloggens karaktär : En kvantitativ innehållsanalys
The aim of this paper is to describe the characteristics of the sport journalistic weblog. To achieve this we have used the following questions: Which themes are included in the sport journalistic weblog? How much text does the sport journalistic weblog content? How often is multimediality incorporated in the sport journalistic weblog? Which references occur in the sport journalistic weblog? How many hyperlinks occur in the sport journalistic weblog? How many of the hyperlinks is internal respective external? How often does the sport journalistic weblog offers possibilities to interaction between the journalist and the reader? How often does interaction between the journalist and the reader occur?The theories we have used is both online publishing and Jan Schmidt?s analytical framework on blogs. Online publishing describes an important part in our paper, online journalism, which in turn describes three important definitions for this paper; hypertextuality, multimediality and interactivity. Jan Schmidt?s theory is central to understand the phenomena, and functions as a starting point in the analyze part.
Bonus och ägarskap i svenska storbanker
In this master thesis we are trying to investigate whether the heads of the four major Swedish banks are receiving compensation because of their own performance. We have investigated a number of parameters in the reporting and compensation description of Handelsbanken, Nordea, SEB and Swedbank and compared it to macro data.We have used publicly available information from the banks as well as macro data from 1998 to 2009.We have come to the conclusion that the revenue and profits of the banks are heavily influenced by external factors and that there does not appear to be a clear link between a CEOs actions, the reported results for the bank, the shareholder gains and the compensation for the CEO. It appears as if the bonus payments to a CEO may depend more on parameters beyond the CEOs own control than the performance of the CEO..
Tillförlitlighet hos information som hanteras av flera användare och genom flera system
When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..
Modell för fördelning av kostnader i lager
Distrilux International AB, a company within the Electrolux-group, works among other things with storing of products from other companies in the Electrolux-group. This rapport contains a cost analysis of the two Distrilux warehouses in Motala and Mariestad. The company offers five services in these warehouses, in-loading of products from a local factory and from external factories, storing, out-loading of products to Sweden (domestic) and for export. Since there has been some hesitation of the accuracy of the price-model of today, a master's thesis has been advertised. The purpose of the thesis has been to investigate the agreement of the price-model of today and the apportionment of the costing in warehouses.The main problem is to determine which activities is to be considered important in the price-model.

Implementering av mjukvarubaserat PLC-system för reglering av magnetiseringen av en synkrongenerator
In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

Häxor vs. Häxor : En studie av häxor i TV-serier och deras motsvarighet inom wicca
This essay examines how witches are portrayed in American produced TV-series in the year 2000 and forward, what elements could have effected that portrayal in the series and also how this portrayal differs itself from witches within Wicca. The material used for this examination are the TV-series Charmed, The Vampire Diaries and Witches of East End and as comparing literature; Living Wicca, The Spiral Dance and Witchcraft Today. The methods used for this process are discourse analysis and content analysis. I used theories of Pierre Wiktorin about religion and popular culture. I used three themes (Characteristics, Practice and mode of thinking) for the processing of the material and to structure the result.
