Vid Positionsbestämning av radiosändare med TDOA(Time Difference Of Arrival) är det traditionella sättet att låta varje uppmätt tidsskillnad definiera en hyperbelgren på vilken sändaren befinner sig. Skärningspunkten mellan två eller fler hyperbelgrenar ger sändarens position.Målet med examensarbetet är att identifiera möjliga sändarpositioner och detektera mångtydigheter. Problemet har lösts med kägelsnittsmetoden som låter tre mottagares positioner och deras uppmätta tidsskillnader definiera ett kägelsnitt där sändarens position är i en av dess fokuspunkter..

The purpose with this study was to examine which opinions and knowledge the directors have about the physical residential environment's importance on accommodations for people with dementia disease and how they do to create and to maintain a good physical residential environment. The issues have been: Which opinions and knowledge the directors had about the physical residential environment's importance for the people with dementia? How did the managers work in order to create and maintain a good physical residential environment? We had four themes, homelike environment on the accommodations, priorities on the accommodation, care/nursing in the physical residential environment and the manager?s possibility to influence the physical residential environment. The study followed a qualitative method. Five managers were interviewed on four accommodations and the managers were said to work actively with the physical residential environment.

There are problems with poor quality, poor scheduling and poor working climate in the Swedish construction industry. Many parts have been involved, trying to solve the problem.This spring a new planning and building-law becomes final. In this law, the requirements set on the controls are greater. Hopefully this will lead to fewer construction errors. The requirements set on the working environment have also increased, forcing consultants and contractors to focus on safe workplaces.For each project requiring a building permit, an inspection plan has to been drawn.

The aim of this thesis is to seek understanding of which images there are about the ?others? in the society. For this study, four women in the ages of 21-23 years old were interviewed during April 2005. The empirical material was analysed with Laclaus and Mouffes discourse analysis. One conclusion is that the images of the ?immigrant? and the ?immigrant women? are created opposite to the ?Swedes? and the ?Swedish women?.

Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.

An Interoperable Fare Management system for public transport has been a struggle for the actors in industry of public transport. A lot of effort has been put into creating a smart card solution that enables the travellers to use the same card for paying and holding the ticket regardless geographical position in Sweden. That project has failed, mostly due to a lack of taking non-technical actors and aspects into consideration during the project process. This thesis highlights the major actors and their responsibilities. The ARKTRANS framework is used as analytical tool to identify different roles. Throughout the thesis a sociotechnical perspective is used. The developed method in this thesis is suitable for mapping of actors and responsibilities in a network surrounding a complex technical system.

This paper aims to describe the geographical changes of Swedish international aid politics since 2007, which was the year the new aid reform of decreasing collaborating countries, came up. To decrease the number of aid receiving countries due to efficiency is not a new idea within Swedish aid politics, but Sweden received criticism from the (DAC) Development Assistance Committee, saying Sweden was active in too many countries, and the government established a policy to decrease the amount of countries given aid. Despite the government?s recent work, science has shown on a failed country focusing. This is followed up in the paper trough examination of statistics to measure the extent of the reduction.

In recent decades, project based work form has taken a dominant role of work for many companies. Developments in the field have progressed rapidly and research has contributed to more efficient working practices. This study describes the elements that a project manager should keep in mind when he leads a project without actually being physically present, complex factors occurred and the basic approach to encounter them. The aim of this report is to examine factors that arise in the context of coordination at a distance and how companies, in their daily work, surpass these obstacles. The study does not include cultural differences, time zone differences and language differences, all very common in project management at distance.

This paper focuses on the relationship between actual victimization and perceived fear of crime among young women aged 18-20 years. Previous studies shows that women are more afraid of becoming a victim of crime than men, even though studies shows that men are victims of crime to a greater extent than women. The purpose of this paper was to examine women?s fear of becoming a victim of crime from a class perspective. To investigate this, we interviewed 16 young women aged 18-20 years with both working class and middle class backgrounds.

To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.

The purpose of the study is to illustrate the choices of sports profiled education amongst pupils in the upper secondary school. Special attention is brought to whether there exist any differences between team- and individual competitors in their view on sport and education. One hypothesis that constitutes the base of the study is that pupils from lower social class, in a higher extent, tend to be team competitors and choose sport activities prior education. The result has been interpreted against Bourdieu's cultural sociology, in which the central concepts are habitus and cultural- and economic capital. The method that has been used is quantitative in the form of a questionnaire study which 277 pupils have answered.                   The result shows that the sportsmen, regardless type of sport, are not influenced by social position regarding choice of education and in their view on education and studies.

Syftet med studien är att undersöka om och hur socioekonomisk position samvarierar med tandlöshet före och efter pensionsåldern samt med försämrad tandstatus. Datamaterialet som används är Levnadsnivåundersökningen (LNU) 1968 och 1981 och Undersökningen om äldres levnadsvillkor (SWEOLD) 1991, 2002 och 2004 och i studiepopulationen ingår personer som intervjuats i LNU och SWEOLD och som var 69-88 år vid tiden för uppföljning. Datamaterialet analyseras med logistiska regressioner. Analyserna visar att lägre socioekonomisk position ökar risken för att vara tandlös före och efter pensionsåldern och för att få försämrad tandstatus under denna period. Egen utbildning och socialklass har samtidigt samband med tandlöshet före respektive efter pensionsåldern, med något starkare samband mellan utbildning och tandlöshet, medan försämrad tandstatus enbart uppvisar samband med socialklass.

This thesis is based on a case study for the real estate manager Mimer in Västerås. Mimer provides a great deal of this city?s rental apartments. Many of their buildings have ventilation systems with a type of heat-recovery called ?heatpipe?.
