Dynamisk modellering av kärnreaktor
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Konsumentbeteende vid köp av ägg : en empirisk studie genomförd med en kvalitativ metod
A decade ago the organic egg production in Sweden was nearly nonexistent (Föreningen för ekologisk fjäderfäproduktion, 2008). A rising demand for these products in the beginning of year 2000 made the organic egg production the most increasing production of all organic provisions. The Swedish consumers value provision production that have a reduced impact on the environment and further protects the wellness of animals and plants (Jordbruksverket, 2010). Today, the organic egg production composes roughly 6 % of the total egg production in Sweden. This indicates that the ambition of Jordbruksverket, which has an organic egg production goal of 10 % of the total production, is not yet achieved.The consumer demand on the market is the driving force for these new products, and the higher prices contribute to an essential portion of the additional costs of organic egg production (Jordbruksverket, 2004).
EBH - Easy Battery Handling
The project Easy Battery Handling - EBH has been carried out in our auspicial and completedfor Devantini Corporation, a development company in Halmstad with its main concern inenvironmental friendly innovations.EBH has solved one of many technical challenges in one of Devantini corporation?s largerprojects. This main project involves the development of an electric powered formula racingcar. The part of this car that involved EBH was the battery handling to guarantee safe andquick battery exchanges during pit-stops.The solution became an entire battery module, hanging on the side of the car on two spearspointing out from the car. The batteries are exchanged by a specially designed trolley that isinserted under the battery module.
"Allt man gör ska ära Gud" : En studie av organisationen Jehovas vittnens maktstrukturers och maktinstruments påverkan på unga Jehovas vittnen i Sverige
The purpose of this thesis is to identify power structures and instruments of power within the Jehovah?s witnesses and investigate how they affect the baptized youths baptized within the organization. The material consists of qualitative in-depth interviews and is analyzed with Foucault's theories of power. The results show that the participants have a very strict relationship to the rules of the congregation and also that they take great care in observing these rules carefully. It becomes evident that young members are exposed to disciplinary measures from the organization.
Planering & produktionsstyrning : Lean filosofin vid produktion av asfalt
Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

Korsförlamning : etiologier, diagnostik och terapi.
This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.

Drömsymboliken hos Boles?aw Lesmian : Kommentarer till dikter ur samlingen ?????? ????????
Anne Reese: Johan Lindegrens vägval : en studie i de faktorer som påverkade enskilda aktörers verksamhet inom Stockholms musiksamhälle 1860-1908, Uppsala universitet: Institutionen för Musikvetenskap, uppsats för 100 poäng, 2007.The aim of this essay is to show some of the factors which affected the production and work of the individual musician or composer within Stockholm's music society in the late 19th century. By a case study on Johan Lindegren (1842-1908) I demonstrate how a musician or a composer functioned in the social structures of the music society and how power affected the work of the musician or composer. This essay also fills another purpose as it gives Lindegren a more detailed biography, which is something that has been missing until now.By applying a concept of power, as discussed by Michel Foucault, to this subject and interacting it with the concepts of musical opportunism, I present a new way of talking about the social, as well as the individual factors that affects the individual musician within the music society.The conclusion is drawn that there are two different types of factors that affects the work of the individual; 1) the social network and power within society, which presents positions and opportunities for the musician and 2) the individual character of musician which determine the way the individual uses the position or opportunity he or she is given..

Utveckling av loadlimiter för bilbarnstol
The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Värmning av avloppsvatten med spillvärme för att förbättra kvävereningen -Temperaturens inverkan på kvävereningen
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
