The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Health care is increasingly complex, which increases the demand for knowledge and expertise. Despite this, the share of specialized nurses, including anaesthesia nurses, has decreased from 65% to 48% from year 1995 to year 2008, according to statistics from the National Board of Health and Welfare (Socialstyrelsen) in 2010. Studies indicate that there may be various factors in the work environment that anaesthesia nurses, choose to leave the anaesthesia profession. The purpose of this study was to examine how anaesthesia nurses experienced the physical and psychosocial work. The study was conducted as a descriptive study with qualitative approach.

Introduction:Corporate limits becoming more diffuse due to the globalization taking place and requirements for analytical strategies are becoming more fundamental parts of organizations.

Therefore, local government activities has increasingly begun to implement Business Intelligence tools, with the purpose to facilitate strategic and operational decisions were the result plays an increasing role in today's society.Purpose:This study evaluates how the analysis tool Qlikview fulfills the function of monitoring and controlling the improved student achievement in public schools.Method:The evaluation has been conducted qualitative interviews with staffs that have leadership positions in each municipality and management and possess a deep knowledge of the analysis tool and its processes.Conclusion:The evaluation has shown positive effects on the monitoring and control of student performance through better control of school operations..

The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

The study´s purpose is to investigate the underlying norms of how the concepts of language development and learning, used in the preschool curriculum. Knowledge of the concepts underlying norms can help to make visible what approach preschool teacher is expected to have to children's language, in relation to development and learning. The results of the study may in turn provide a picture of societal norms on children in preschool and a deeper understanding of the importance of preschool to review and analyze the content of the curriculum, then it is not a foregone conclusion.Theoretical basis is curriculum theory, which involves studying curricula in order to create a knowledge of a society and its cultural, social and economic demands. Norman Faircloughs critical discourse analysis is used as a method, in order to achieve the study´s intention and answer the questions at issues in the study. The critical discourse analysis considers that the discourse is creating the social world through language.The results of the study show that there is a language in the curriculum as normatively may influence preschool teacher.

Civil-military relations ? conditions for cooperationAbstract: Civil-military cooperation is a branch of current interest, both in studies and research. The importance has also increased after the government´s demands in a more developed and efficient coordination of national contribution to international peace support operations. Several studies show that there is a lack of ability to cooperate between different levels of command and other actors. The Swedish tradition of state administration is strong and the responsibility to cooperate lies within the hands of the different authorities.

Uppsatsen syftar till att försöka belysa vissa av de krav som ställs på svenska soldater och officerare som idag tjänstgör i utlandsstyrkan och hur deras utbildning möter de krav de ställs inför. Jag har undersökt vad doktrinen säger om hur försvarsmakten ska lösa sina uppgifter utomlands och vilken inriktning soldatutbildningen ska ha. Jag har sedan försökt arbeta mig nedåt i kedjan genom att undersöka kursbeskrivningar för officersutbildningen vid Markstridsskolan, jag har undersökt utbildningsdirektiv för soldater vid stridande förband för att till sist intervjuat en officer med lång erfarenhet av förbandstjänst. Jag har sedan skapat en kravlista som endast är exempel på de krav som kan ställas på svenskasoldater utomlands idag. Kravlistan skapades genom att studera litteratur som avhandlaroperationer liknande de fredsoperationer svenska försvarsmakten deltar i idag, samt litteratur som avhandlar de psykiska och fysiska reaktioner soldaten utsätts för när denne utsätts för stress iframför allt stridssituationer.

This Master thesis focuses on change conditions and change ambitions in Swedish public libraries. I have chosen to focus on three libraries that participated in a much-debated developmental project sponsored by the Swedish Arts Council almost twenty years ago. The aim of the project was to enhance service-quality, increase user-influence over media acquisition and library routines, and to redefine the concept of quality in the library context. I have made comparisons of the conditions and change ambitions between the project period 1991-1994 and present day 2009. To do this I have analyzed the evaluations of the above-mentioned project and the developmental plans that every municipality in Sweden is required to write according the library-law of 2004.

The aim of this MA thesis is to examine how users regard and receive the services offered by a specific public library. We also examine what the conception of service means to the users and how they perceive this service being offered by the library. We look upon if and to what extent the service conception depends on contact with the library staff. The methods used are qualitative interviews and analyses of documents directing the library activities. The public library we have examined in this respect is the public library of Västerås.

As a great deal of people spend more time with their cell phones and computers than with magazines and TV, markets have begun to explore marketing possibilities in digital media. A common form of marketing in digital media is sponsorship of the cyber stars of the Internet - the bloggers. Sponsorship of bloggers has proven to be a highly efficient method for brands to gain attention and positive attitudes, as bloggers are regarded as fashion icons as well as reliable friends. Another up-to-date marketing strategy that has proved successful in gaining consumer attention is the use of incongruent elements in ads. Incongruence challenges consumer expectations and thereby demands attention.

This essay investigates and compares the readability in two different schoolbooks: Eko Historia (the primary school grade 4-6) and Epos Historia (the upper secondary school). The questions of the survey are:- Which differences in linguistic and layout can be found between books meant for the primary school and books meant for the upper secondary school?- Are the texts easy to read according to the former research in readability?In order to answer the questions structural dimensions as lexicon, syntax, bounds between sentences and narrative voices have been studied. Also the texts disposition and typography have been examined.The results demonstrate that the book designed for the primary school has a verbal structure with an explicit vocabulary, lots of verbs and short sentences. A clear narrative voice gives an impression of spoken language.

 The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.

A third party access to district heating networks has been proposed in Sweden, to increase the competition on the district heating market. Such third party access could create opportunities for the agricultural sector as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel. The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant. In the study, an estimation of the profitability has been made by estimating the cost of the investment, personnel, operating and maintenance costs and costs for the fuel and ash handling.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization. The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.
