En bakgrund till skadorna på Slussens bärande konstruktioner
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.

Ekologisk nötköttsproduktion i Gävleborgs län :
The objective of this study was to make an inventory and a potential analysis of the organic beef
production in the region of Gävleborg, Sweden. A survey was conducted, where a questionaire
was sent to all farmers in the region who had environmental subsidies concerning organic
cropping systems in 2001. In total, there were 701 farmers, of which 46 % participated in the
study. Three slaughter houses were interviewed to get their pictures of the development of
organic beef production. The study shows that there are potentials and interests in the region to
increase the production of organic beef.
Nyanla?nda invandrares etablering i Sverige : En kritisk diskursanalys av den nya lagen om etableringsinsatser fo?r vissa nyanla?nda invandrare
This thesis is a qualitative study of a new law that was applied in December 2010. The law is called Lagen om etableringsinsatser fo?r vissa nyanla?nda invandrare, and is meant to help newly arrived immigrants that come to Sweden to establish themselves in the Swedish society. The aim of the study is to see what discourses the Swedish government produces as a result of this new law. Interesting for the study is to see what happens in the implementation stage at a local level, in this case in the municipality of O?rnsko?ldsvik.Theoretically and methodologically I emanate from critical discourse theory and institutional theory.
Vindkraft och landskap
The current debate about environment and climate change has contributed to more andmore investment in alternative energy sources such as wind, solar and biogas. The Swedish Parliament has set the target that wind power should supply 10 TWh in 2015.In Sweden, wind power establishment began in the early 1980s. Since then the development has gained a tremendous momentum. The purpose of this study was to find out what problems wind power brings and what power relations that exists in connection with wind power establishment and how the landscape is affected by windpower construction, focusing on some cases in Falkenberg and Varberg. This study shows that wind power establishment is a very complicated process.

Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion
Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.
Does nuclear power plants affect house prices? : a hedonic price model of Forsmark nuclear power plant
Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.
Att genom fiktion skildra en verklighet : En kvalitativ studie i hur maktstruktrurer beskrivs i BBC:s tv-serie The Hour
The objective of this study was to investigate how power relationships between journalists and politicians were shown in the fictional BBC tv-series ?The Hour?. We wanted to investigate how these power structures is narrated by the producers of the series and what impact the narration could have to the audiance of the 21th century.We choose to analyse a total of 12 scenes from all of the six episodes, which are all set in Britain during the beginning of the Suez Canal crisis in the 1950?s, all seen from a BBC editorial point of view.In our analysis we chose to use two different kind of methods, the first one was a situation analysis and the second one a text analysis. The situation method was useful to get a perception of the relations between the participants .The text analysis we used to analyse what was said in the tv-series and to interpret underlying motives.The fictional form necessitated a personalization of power structures, in the sense that each and every power was represented by a single character; political power was for instance represented by the character of Angus McCain.
VIBRATIONSSKADOR - FÖREKOMST OCH FÖREBYGGANDE : Analys av ett strukturerat arbetssätt inom bostadsproduktion
Ask any constructional worker and there is a high probability that this person knows a colleague with pain or other disorders caused by working with power tools.According to the Swedish Work Environment Authority 71 percent of the Swedish constructional workers is exposed to vibrations at least 25 percent of the working hours. Despite this, the number of reported occupational sicknesses caused by vibrations is as low as 1, 4 percent.JM Ltd. is one of the largest constructional companies in Sweden. Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company?s long-term goals.
Proviant - sparar hushållets pengar på ett miljövänligt sätt
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.
Översvämningsanalys med hänsyn till Länsstyrelsens handbok : Planering för stigande vatten i Kristinehamns kommun
This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.
Studie i en studio - Undersökning av producenter och gitarristers syn på studioinspelning av elgitarr.
As I recently started to record in a studio, I almost immediately came to the conclusion that getting the right sound is not easy. I became curious about my recording procedure. What did I do wrong? How to place the microphone? Use of equipment? How is it possible to modify the sound afterwards? Are there any special methods that are commonly used among producers and/or guitarists? My thoughts ended up in a question ? What do producers and guitarists think of the guitar sound during a recording session in relation to the final production? In my research I interviewed two producers and two guitarists about guitar recordings. The results show that the quality of the guitar sound is in relation to production and style of music.
Vanmakt och motmakt i personliga assistenters relationer till brukare
The aim of this study was to examine the aspect of power in the relationship between the personal assistant and the disabled person he or she works with (the user). The study was based on interviews with five personal assistants who worked for private companies that provided personal assistance. Seven themes were identified and discussed. These were: the users amount of control over the assistance given, the workplace environment, the working conditions, the organization of personal assistance by private companies, the assistants recourses and usage of power and the users participation in chores. To analyze these themes I used Foucault's theory of power and the perspective of Human Resource.
