Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

To identify the underlying forces behind a product hype is difficult and the findings often seem random and unclear. To create a better understanding behind the affecting mechanisms would consequently be a valuable addition to the surrounding research area. The purpose of this paper is to understand if there exist common denominators between different product hypes and in such a case, which these are and how they function. By conducting a case-study on four products which have enjoyed immense sale success on the Swedish market, the possible presence of structural resemblance will be analyzed. From the study we can conclude common denominators such as the presence of an underlying trend and an overbalance of indirect decision basis do exist.

The purpose of this essay is to contribute to an extensive understanding of former criminals and addicts.

Criminality and addiction is a complex problem. There are many different factors which contribute to develop this. The most differential factors are; insecure childhood, low self-esteem and wrong kind of friends.

SUMMARY The purpose of this study was to explore how nurses in the emergency department experience and cope with stress in their workplace. The study had a qualitative, descriptive approach and was based on nine individual, semi-structured interviews. They were then processed using content analysis. The content analysis of interviews resulted in two categories, "the nurse's experience of stress," "the nurses coping with stress." Together, the categories highlighted how nurses experienced stress during and after their shifts. The study showed clearly that all nurses experienced and coped with stress in their daily work activities..The authors noticed that stressful time for the nurses were repeated at each session and were similar in character.

Through 10 qualitative interviews of adult women, all affected by childhood alcohol abuse, the article tries to get a better understanding of how these women coped under these circumstances. The article attempts also to better understand how the women?s experiences of support during childhood have benefited them and how they feel as adults today..

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

Multiple sclerosis is a disease whose course is capricious and unprediactable and the exact cause of the disease is still unclear. The purpose of this literature review was to describe factors that can effect quality of life of people with diagnosis multiple sclerosis. The results shows ten different factors that effect quality of life of people with MS: fatigue, activities in daily life, position of dependence, limits of the functional abilities, sense of guilt and shame, comunicationdifficulty, social network, emootional factors, depression and degree of difficulty of the symtomes. Work has been shown to bee a major factor that can make people with MS feel worthy and experience quality of life. Nurs is an important keystone in care of people with diagnosis multiple sclerosis..

Modern technology and fast development of heat pumps, the hunt for savings in energy consumption and the strive for environmentally friendly energy sources, convenience, and financial profit, have made heat pumps a reasonable alternative for the heating of houses.When the heat pump starts it will consume a considerable amount of current, which may result in a short-lived voltage-drop if the power grid is weak compared to the start-up current.The company Fortum Distribution which owns and administrates electrical network is interested in an investigation that deals with heat pumps affect on the quality of electricity.The purpose of this investigation is to study fast electrical fluctuations (flicker) as a result of start-up currents for single as well as multiple heat pumps on the same electrical station and from this evaluate whether there will be any problems installing heat pumps..

The aim of this study is to illustrate, and analyze how social workers are able to more effectively pursue operative possibilities within their own particular organizations. The main question concerning this issue is: How are social workers, working within the same district organization able to realise any potential for co-operation with other social workers, in different locales and units, yet working within the same organization? Following on from this question, further issues arise such as: 1. How do the varying demands of the clients affect the workload of the social worker? 2.

AbstractBackground The importance of establishing well-functioning parent-teacher relationships are clear objectives in the Swedish National Curriculum for Preschools, (Lpfö 98, Lpo 94 & Lgr 11 chapter 1-2). Parental involvement in preschool activities is seen as important for several reasons. Facilitating healthy child development, learning and socialisation are some of these reasons. During the past twenty years Sweden has become a multicultural society. Today, people from more than 170 countries live in Sweden, and about 18% of the population are first or second generation immigrants.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.
