Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.

This thesis aims at analyzing why the municipality of Flen, in the eastern part of Sweden, has experienced strong depopulation for the last forty years in spite of its relative vicinity to Stockholm. The study uses current theories on regional developement, population theory and theories on regional enlargment to help explain and to evaluate the different regional factors that affect the developement of Flen on the local level. The thesis is primarily focused on the subject of regional policy and strategies to meet regional depopulation. The study also gives a presentation of the strategies of major regional institutions as well as analyzing what impact regional policy have on local policy in the municipality of Flen.Interviews with local officials, politicians and other people representing the population of Flen were carried out to achieve a better understanding of the specific challenges that the municipality faces and of the measures that are taken to meet them. Regional policy in Sweden prioritises measures that promote regional enlargment to link the housing and labour markets together with the regional infrastructure.

During 2008 we experienced an expansion of large scale investments in foreign farmland. This increasing trend has become a political hot-spot, but there is not much research available within the field. Due to a lack of research it remains a vital task to outline the potential effects of this trend. Drawing on existing ideas from some of the main actors within the field, The Food and Agriculture Organization of the United Nations (FAO), The World Bank, International Food Policy Research Institute (IFPRI) and the latest G8 summit on agriculture, four main purposes are set out for this paper. First, to outline some of the underlying mechanisms behind the trend is considered crucial for the understanding of the nature of these investments.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

Svensk hälso- och sjukvård är en informationsintensiv bransch som står inför en stor utmaning avseende de informationsteknologiska lösningar som används idag och hur dessa lösningar bör utvecklas framöver. Vårdpersonalen efterfrågar att den teknologi som används ska vara flexibel och anpassad till arbetssituationen samt följa flödet i patientprocessen. För att utveckla lösningar anpassade till vård och omsorg som kan stödja användarna i deras arbetssituation krävs att metoder utvecklas utifrån användarna och deras arbetskontext i en distribuerad arbetsmiljö. Genom att ta fram sådana metoder utifrån ansatsen distribuerad kognition blir det möjligt att identifiera informationsflöden och de verktyg som används utifrån de fysiska förutsättningarna i arbetskontexten. Distribuerad kognition utgår från att människans tänkande ses som ett fenomen som utgår från social, kulturell och kontextuell interaktion samt interaktion med artefakter, Kognition anses på så sätt vara distribuerad.

Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

Purpose: The purpose of this study is to increase the understanding of how a bank?s features and internal factors have affected its choice of method in calculating the capital requirement.Theoretical and Empirical Method: The research strategy of this study has been of a qualitative nature with a deductive approach. The choice of method was depth interviews with respondents from a targeted sample of Swedish banks. These respondents were chosen based on the knowledge they possess as key employees in the capital requirement process and their involvement in choosing their banks? method for calculating the capital requirement.

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

Ever since Internet revolutionized the world, e-stores and e-commerce has grown into becoming a natural part of consumer's everyday life. Much thanks to it's facilitative and time saving characteristics. Online, consumers are provided with a huge assortment and the opportunity to shop any time they like. Yet, the absolute greatness of e-stores is the possibility to push prices below the physical store price, which seems to be most appreciated to a large extent by consumers worldwide. The fact that e-store sales in Sweden grew 14% last year verifies this.As more players step into the virtual world of e-commerce the competition gets tougher.

This study is a part of a Swedish research and development project that is about heat-treated wood and is led by the Swedish University of Agricultural Sciences and Luleå University of Technology. Products that are heat-treated already exists on the market, foremost the Finnish brand ThermoWood®, bur the project group want to find out if it would be possible to start a Swedish production with somewhat different applications than what is common today. The heat-treated wood has many attributes that have changed in the heating process. It becomes more biologically durable, it gains stability in form and dimensions and it becomes darker and looses several unwanted extractives such as resin. Disadvantages that can be mentioned are that the wood becomes fragile and the strength properties changes. My main purpose with this study is to look into customer involvement in the early phase of product development. I also want to find out if the customers I interview think that the product is worth working with, which means start a Swedish production.
