The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

Injuries and sick-leave is a common feature for reinforcement workers today. This is mainlydue to the fact that reinforcement work is done in an exposed environment with many stressfactors and highly repetitive work. These operations are often carried out in unsuitableworking positions, these positions creates a major burden on the bones and joints and causesmicro- damages on muscles. With repetitive work these injuries are not given time to healproperly and will gradually become worse.The body will not be able to handle the stress of working in a work environment such as thisand musculoskeletal disorders can be a result of this. The injury will make itself known aspain in the musculoskeletal system and causes reduced movability; the injured worker willtherefore not be able to perform the same work tasks as before.

In today's society there is tougher climate both financially and time wise. Accountants working under tight deadlines leading to the compromise between quality and quantity in the audit process and them therefor are being guilty of so-called reduced audit quality, RAQ. Reduced audit quality involves intentional actions designed to somehow reduce the evidence contained in the audit. We examine in this study the impact of time budget pressure (TBP), underreporting of time (URT), ethical organizational culture and charismatic leadership has on the frequency of RAQ.Previous research has already shown that there are clear links between TBP and RAQ, between URT and RAQ and between ethical culture in organizations and audit quality available. Five hypotheses were designed to the study.

Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

From a management point of view, enabling organizational creativity is often referred to as reducing immediate control, increasing autonomy and enhancing the access to slack resources. At the same time, the business environment of today is fiercer than it was only a decade ago, and this renders a quest for more efficient approaches to competitively run a business. This paper aims to examine creative industries and more specifically try to identify a set of elements that are common for successful companies. As this industry has not been subject to any considerable array of studies, this thesis seeks to establish a structure for how to take both organizational models and leadership theories into account when developing an understanding for the process, organization and leadership of the creative business. By studying six separate creative companies, our findings suggest that conventional theories on organizational creativity do not adequately account for all factors that contribute to these companies' creative success.

The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.

The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.

The purpose of this study is to describe how, and if, discourses about self-harm in young people has been changed from the late 90-s until today. We chose to do this by studying films where the content of self-harm is a big factor. The study is built on a narrative research, we did however analyze it as a discourse method. The issues we have concentrated on are: Is there a significant quality that describes an individual who cut themselves? How can this phenomenon be seen from a gender point of view? Is there a specific group of people who is labeled as a person who cut themselves from the public? The result from this study show us that self-injury, from symptoms of a (bad) mental state, is a strong discourse where the views from the society lets it become more acceptable.

Navigating to different locations isn?t always easy. Imagine then how it is for people with a visual impairment to walk across the street or to get from one point to another. The Swedish Association of the Visually Impaired (SRF) has pointed out that today's society is not sufficiently accessible to people with visual impairment and there are improvements that need to get done. Technology is something that has evolved a lot this last decade and occurs today almost everywhere in our environment.In some areas, technology has facilitated people's daily life very much and we have therefore chosen to examine whether a combination of several technical functions integrated into the fictive artifact called Eyenavster can facilitate outdoor orientation and increase the accessibility for people with a visual impairment.Qualitative data collection methods have been used in this study by six interviews to answer our question.

The purpose of this essay is to describe the organization of the Swedish Animal WelfareAgency during the time it was in operation.
