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 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.

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.

Syftet med uppsatsen är att få en bild av på vilket sätt informations- och kommunikationsteknologier (IKT) används och hur dessa teknologier stödjer studenternas samarbete på distans. Vi har genomfört en fallstudie på Luleå tekniska universitetet på avdelningen för Systemvetenskap. Denna studie utfördes från ett användarperspektiv. Resultatet av undersökningen visar bland annat att de flesta studenter föredrar att arbeta med uppgifterna självständigt. När studenterna samarbetar väljer de ett kooperativt sätt framför ett kollaborativt.

Syftet med denna uppsats är att beskriva och tolka berättelserna och berättandet inom SAS, Scandinavian Airline Systems. Vi vill därigenom erhålla en förståelse för denna aspekt av organisationskulturen. Vi beskriver vilka berättelser som cirkulerar inom organisationen och försöker utröna deras betydelse och vilka skillnader som finns inom organisationen. Genom våra intervjuer med SAS anställda har berättelserna visat sig ha olika funktioner. En av de viktigaste funktionerna är berättelsernas förmåga att fylla de informations- och förståelsebrister som uppstår i organisationer, inte minst i en organisation med SAS komplexa karaktär.

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.

Majoriteten av dagens moderna organisationer har implementerat någon form av informations- och kommunikationsteknik (IKT) i sin verksamhet. Många ideella organisationer tillämpar också denna teknik, dock skiljer sig förutsättningarna för dessa organisationer. Eftersom IKT är en kostsam investering är det av vikt att det leder till önskade effekter. Flera olika faktorer påverkar användandet och effektiviteten, att tekniken finns att tillgå medför inte per automatik att kommunikationen är tillfredställande.Syftet med denna uppsats är att undersöka hur ny informations- och kommunikationsteknik har implementerats i en ideell organisation. Studien inriktar sig på en fallstudie av hur Frälsningsarmén har implementerat dessa tekniker i sin verksamhet.

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.

Studiens huvudsyfte var att undersöka hur elever använder och uppfattar informations- och kommunikationsteknik, (IKT) i skolan respektive hemmet, samt studera detta ur ett genusperspektiv. Syftet var även att undersöka vilka IKT-verktyg som används i respektive miljö samt på vilka sätt dessa används. Vidare undersöks också elevernas uppfattning om möjligheter och hinder med IKT. I studien har elever från en IKT-profilerad grundskola, år fyra, intervjuats. Resultatet visade att de medverkande eleverna i studien hade en positiv inställning till IKT generellt, då de också visade att de var medvetna och insatta i en mängd olika företeelser inom IKT-området.

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.
