The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.

The theme of this thesis is citizen participation in the planning- and design process. It turns to everyone that studies landscape architecture or work as landscape architects and I hope that it can function as a ground for discussions as well as a source for inspiration. Rågsved is a suburb south of Stockholm. Just outside the centre of this suburb, a small industrial area called Snösätra, is located. In a few years time the leaseholds for the small industries will expire and the key question is: What will happen then? This is my general concern and it was the main cause for me to start this particular work. How do you attend to a place that appears like blank sheet of paper? To an empty page that can be filled with an infinite number of different formulations.

Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this case bridges or culverts have to be built. There are many different kinds of culverts and depending on what type you choose and how you place the culvert, the watercourse and the water organisms can be harmed in different ways.

Inspired by how to sketch a light cone from a flashlight in a comic I wanted to create an armature carried only by its own light cone. To manage this challenge I sketched in an architectural and sculptural way, where I chose to ignore the function of the lamp as long as possible.As a result I developed an armature with a stunning shape, with an illusion that it was carried by its own light cone. It could be hanged on a wall, placed on a table, pushed against a ceiling or standing on the floor.Depending of its size the light cone from the light source lightens up the surface and draws attention to the otherwise forgotten wallpaper or the undisposed statue in the darkness of the city..

The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

The purpose of this study was to get an idea of ??how the leaders in the real estate industry perceive and manage boundless working conditions. Questions that were answered were how the leaders in the service influence and control the employees' working conditions. Also how the communication strategies are designed to facilitate the work towards common goals, when tasks are not limited to the workplace. The study examine if boundless working conditions is characterized by unspoken expectations.

The present research examined both automatic and controlled processes in newpapers ability of priming racial stereotypes via the portrayals of people of foreign extraction. The automatic process were examined through articles which; a) involved an illegal act or b) the act was not illegal but morally questionable. Swedish-born subject?s explicit opinions against foreign people were also measured through ?The Modern Racial Prejudice Scale?. In the experiment participants read four different articles which included; Swedish person/noncrime, foreign person/noncrime, Swedish person/crime and foreign person/crime.

Aim: The aim is to create a review that examines different forms of massage therapy and their effects on hypertension.Method: Literature review of 10 scientific articles on the subject of massage and its effects on blood pressure. The literature searches were made with PubMed and Cinahl using the keywords "massage therapy", "effects" and "blood pressure".Results: The articles showed that massage had a positive effect in lowering blood pressure. This could be explained by greater extent of relaxation in the participants investigated and an increased activity of parasympaticus and reduced secretion of stress hormones. The articles do not agree on what form of massage therapy is most effective in lowering blood pressure and it is uncertain for how long the effect can remain.Conclusion: Massage is usually seen as a treatment without scientific basis. There is evidence that suggests that massage therapy is an effective treatment for lowering blood pressure.

With knowledge of how the southern Swedish forests have been affected by storms the past years, this study intended to find out which factors affect the storm firmness of a stand the most. The study was based on data from stands in the, by the storm Gudrun, affected area. The results of the analyses that tested the stand factors that influence the amount of storm damage to the greatest extent showed that the storm sensitivity of Norway spruce stands were largely due to previous management actions. The factors that could be controlled by thinning and had relevance of storm damage standpoint, according to the results were; the dominant height, volume, basal area weighted mean diameter and stand age at last thinning. In this study, these results are not as clear for Scots pine.

This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support.The purpose of this paper is to produce a design concept for a simulator as well as conducting research on the topics: mental and physical learning abilities, psychomotor abilities, visual perception, hand-eye coordination, confidence, simulators and Serious Games. The conducted research will be the foundation for the design concept which will be implemented in our co-workers', Henrik Djerf & Daniel Gomez-Ortega, prototype.

Recently there have been a lot of talk a about the financial crisis and recession. This is understandable since the crisis, which initially was limited to the U.S. now has spread its concern globally in form of bankruptcies, less investment and lots of people have lost here jobs. The purpose of this thesis is to examine how the financial crisis have affected the construction industry relating to market and personnel, but also examine what measures the construction companies have taken. The examination was carried out by information received from the majority of construction-related websites which then was followed up with interviews in the various construction sectors.

Jumper´s knee is a common overuse injury due to repetitive microtrauma to the patellar tendon. It is especially common among athletes who are involved in sporting activities that involve jumping or fast running. The term jumper´s knee was adopted after Blazina published his original paper in 1973. Its pathology can be considered as a partial or total rupture of the patellar tendon in one of its three insertions. The aim of this literature study was to review the methods used to treat this condition and the results obtained focusing on pain relief and returning to previous sport or level of activity.

This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
