The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

The study emanates from the national quality registry for persons with severe and profound hearing impairment. The aim was to examine possible differences between signing deaf and adults with acquired severe hearing loss, with reference to self-assessed problems, how the hearing loss influences daily life.In total 234 adults aged 30-90 years were included (128 women, 106 men). In the registry, there are background variables and questions that the patients have answered. The results, indicated on a visual analogue scale (VAS) from 0-100, from a question ?To which extent does your hearing loss at present influence your life?? were analysed.The study was performed by pooling the results of VAS and dividing the patients into signing deaf and those with acquired severe hearing loss, and in age groups 30-60 and 61-90 years.

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

The aim of this study is to examine the experienced life situations of siblings growing up with a brother or a sister diagnosed with autism. The study is qualitative and therefore suitable to the purpose of studying the informants´ own experiences. Three women and one man, aged between 18-24 years, were interviewed through chatt programs on the Internet. The constituted perspective is phenomenological and the analysis were made by identifying meaning units in the text from the interviews. The theory used to interpret the result is systems theory and more specifically the structual family therapy by Salvador Minuchin.

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Biological diversity is one out of four dimensions, characterizing the subject of Biology ac-cording to the school curriculum. As a concept, biological diversity had its break through at the UN environmental conference in Rio de Janeiro in 1992, where the convention about bio-logical diversity, named CBD, was signed. According to the convention, almost all the na-tions of the world have engaged themselves to preserve the national diversity of species, in-cluding the diversity of genetics and ecological systems.This thesis focuses the biological diversity from the perspective of school books. The aim is to find out how the biological diversity is presented in biology books for students aged 12-15 years.In 1994, the current Swedish secondary and high school curriculum called LPO-94 was pre-sented. The biology books used in this study were published between 1994 and 2007, all of them exist in many editions and are published by three different publishers.The conclusion of the study is that all the biology books that were examined have reached different levels of the development in the field of biological diversity..

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

Companies today need to be more focused than ever on having an active Human Resource Management culture. This is not only because of the companies? concern for their staffs wellbeing, but for the companies? effectiveness in the long run. The reward systems which many corporations use today, to both keep their employees and attract new ones, is a well researched subject by scholars as well as journalists. Earlier research has suggested that it is important to implement an active Human Resource Strategy.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.
