An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

This report is our Master thesis. Our work has taken place at a one-stop-shop in Sölvesborg during the spring of 2002. We have conducted ethnographical studies concerning the one-stop-shops frontdesk and telephone exchange. During these studies we became aware of some differences under which the daily work was to be carried out. When operating the switchboard the staff usually work alone and perform the tasks individually.

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Social work in Sweden has historically been mostly done by the public sector andthe work has been regulated by law. In the last two decades, private and voluntaryactors have played an important role as providers of welfare state; one of theseplayers is the Swedish Church. The aim of this thesis has been to describe thework the deacons perform in the Swedish Church in a medium-sized municipalityin Sweden. To find out how much freedom of action the deacons themselves feelthat they have and if they feel that their work is influenced by the social work thatother performers are doing. In order to reach the goal, a qualitative approach wasused where seven deacons were interviewed.

This study illustrates the views of working socialpedagogues when it comes to socialpedagogical and social work within compulsary schools. The focus of the study is on how social problems can be prevented and get noticed among children and youths in compulsary school, and what possibilities of development there are in preventive social work. The socialpedagogue?s capability for supporting this development, together with people that are important in the children?s and youths?s lifes, opens up new possibilities in the future for the social work in schools. The main concepts in the study is treatment and attitude, interaction and cooperation with different people inside and outside the school as well as individual- and grouporientated work.

The company Pilotfish has developed the system MIVEO which is used by car-sharing to wirelessly monitor, book or otherwise manage a fleet of cars. In a car pool the system has three different types of users with varying degrees of eligibility. These are end users, administrative and service personnel. We have chosen to focus on opportunities to streamline the administrator and service personnel work with a mobile service, as these users of MIVEO often are movable and mobile. From this position we have in the study attempted to answer the following question: How can mobile services used to streamline administrative tasks? This study is about developing a mobile application that will contain the same features as the existing system, but must be mobile suit.

The thesis aims to examine how companies optimize the human capital from a value creation perspective. The value creation will be related to transfer of knowledge, recruitment, staff turnover and development. The thesis has a deductive approach and six qualitative interviews have been conducted. The results from the interviews will be strengthened with a quantitative data analysis of two measurements; value added per employee and human capital efficiency. The theoretical framework includes definitions of human capital.

Detta är en kvalitativ intervjustudie som undersöker maskinpersonalens upplevelser av att använda headsetkommunikation i arbetet ombord. Totalt sex stycken maskinbesättningsmedlemmar intervjuades om deras upplevelser av hur headsetkommunikation har påverkat utförandet av arbetet, personlig säkerhet och tidseffektivitet. Resultaten som framkom av intervjuerna visar på att kommunikationen förbättrats med headsetkommunikation genom att talkommunikationen inte begränsas av höga bullernivåer vilket leder till minskad röstbelastning. De intervjuade vittnade om att den förbättrade kommunikationen underlättade i arbetet och ökade den personliga säkerheten genom att risken för missförstånd minskade samt att maskinbesättningens situationsmedvetenhet ökade. Förbättrad ergonomi vid svåra arbetsställningar i trånga utrymmen jämfört med handburna radioapparater upplevdes även det som en fördel med headsetkommunikation.

This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays.

The aim of this essay is to give a picture of the extension work at Partille Public Library, asit is today, as well as to investigate if there is a need to reconsider the way of working at thelibrary.Qualitative interviews have been made with the extensive librarians and certain local governmentpoliticians, borrowers and personnel at hospitals as well as other institutions.The extension work at Partille Public Library corresponds quite well to the intentions whichare stated for the work in certain important investigations made by the Government. Theborrowers and the personnel are quite satisfied with the work and are only pointing out a fewviews on changes. The politicians mean that the aim of the extension work of the library ison one hand to give service to certain more or less neglected groups and on the other handto reach new book readers..

The aim of this study was to gain a greater understanding of what social workers perceive to be mentally demanding and emotionally challenging work, and which strategies they use to handle it. I chose to interview six social workers, three of them had long experience of social work, and three of them had worked for less than a year. The justification for this choice wasthat I wanted to interview people with different experience of social work over time, to be able to see possible differences in what was perceived as mentally demanding and emotionally challenging work, and how it was handled. The social workers were interviewed with a semi structured interview manual.The results showed that the organization of the social service is not fitted to the work that social workers execute. This means that what is perceived as mentally demanding and emotionally challenging work largely depends on this.

The focus of this essay is Swedish bilateral development aid. With the help of organization theory I analyse the development aid strategies and policies of the 1990s, in order to examine how and why they were introduced. I investigate three different types of aid organization, namely structural adjustment programmes, political conditionality tied to aid co-operation, and equality policy as part of development co-operation. I analyze the introduction and subsequent use of these three co-operation forms to see whether they were applied and adopted into Swedish development aid because more efficient measures were required or because they were the most recent and modern ways of dealing with development co-operation.Organization theory presents these two ways of analyzing organization. They are occasionally competing and sometimes complementing each other in explaining organization.

The aim of this study is to explore the effects of probation officers and their work. The following questions have been asked to come to a conclusion: How do probation officers view their work and the purpose of it? What are the effects of probation officers work? The approach of the study is of a qualitative nature and has been conducted by interviewing three officers of the correctional service system, three probation officers and two ex-criminals that have been on probation. The selection is based on a snowball type selection. To analyse the results of the study we have applied previous research and phenomenological theory to examine the experience of correctional service officers, probation officers and ex criminals.
