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.

Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.

Cost allocation ? a study of how Swedish energy companies allocate costs between electricity and district heating in a combined heat and power plant District heating is today the most utilized alternative for heating in Sweden. In a combined heat and power plant (CHP) electricity and heat are cogenerated. The environmental and economic advantages with this kind of production are high. A problem in a CHP-plant is to allocate costs between electricity and heat since both products are generated in the same process.

How does a social welfare officer know when a parent with mental illness or behavioral symptoms is harmful to the children? As a social you are confronted with different ethical dilemmas on a daily basis. The social welfare officers have to follow their own authorities, laws, guidelines and regulations while at the same time do everything to satisfy their clients? needs. This inconsistency can sometimes be difficult to handle.

This paper is named ?The status of the programme is low? ? Gymnasium teacher?s thoughts and attitudes towards students in the vocational- and the educational programmes. The purpose is, as the title reveals, to examine the attitude of four teachers in the Swedish gymnasium towards the vocational and the educational programmes and the students that attend either one of them. This purpose is accompanied by research which says that the educational programmes? status is higher than one of the vocational programmes.

This essay aims to emphasize and clarify the positions that exist within the current globalization debate. The positions are the neo-liberal, the opponents, the pragmatists and the skeptics. The text presents and explains their ideological, moral and political positions and beliefs about the world, the nation state, the society and the individual; in light of Steven Lukes? and Antonio Gramsci's theories regarding the interaction and the relationship between power and hegemony. The methodological starting point is the ideology-critical analysis; in which their arguments in the current globalization debate is highlighted and categorized.

Uppsatsen går ut på att undersöka om det finns skillnader på tekniker som används vid mixning av basinstrument i musik avsedd att spelas på dansgolv som t.ex. house, trance, hip hop, R n´B, osv. och annan musik som vanligen spelas på radio, TV, Mp3-spelare, bärbara datorer osv. som rock, metal, jazz, pop, osv. Musik som är dansinriktad och spelas på dansgolv upplevs oftast som starkare i basen, då den också har basinstrumenten som den viktigaste för att skapa ett ?groove?.

J.O. Mallander?s Extended Play (1968) is a sound recording, a readymade, of the counting of votes in two presidential elections in Finland, during 1962 and 1968. A voice repeats monotonously: ?Kekkonen, Kekkonen, Kekkonen, Kekkonen, Kekkonen?? Although the Finnish president Urho Kekkonen represents, almost personifies, the politics of the post World War II period in Finland, Extended Play does not explicitly address the political. Rather, as this essay argues, it engages in the discourses of power and politics by providing a temporalization of its fixedness, or what Jacques Derrida terms the proper.Extended Play is, in parallel with Derrida?s critique of western metaphysics, a deconstruction in sound that challenges the state ideologies conveyed in the process of the counting of votes, where the presuppositions of the presence of the voice characterizes the ambiguities of power that Kekkonen?s politics of neutrality represent.Mallander?s readymade emerges as a double of the game theory strategies of the Cold War, a mimetic surplus of the administrative control mechanisms of sound recording.

The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.

Vindkraftverk ansluts idag i snabb takt till elnät runt om i världen. Elnäten är ofta inte tillräckligt dimensionerade på platser där vindkraftutbyggnad är lämplig vilket leder till ett behov av nätförstärkning. Förstärkning sker konventionellt genom att övergå till en högre spänning, något som kan vara förenat med stora kostnader och ledtider. Bland annat därför har en filosofi med beteckningen smarta elnät uppstått, som handlar om hur elnätsystemet ska se ut när det är mer anpassat till de nya energikällornas karaktär och samtidigt medför ett mer effektivt totalutnyttjande. För vindkraftverk kan det då handla om att i högre grad än idag reglera produktionen och understödja nätet, t.ex.

I ett försök av mig att ge spelmediet samma sorts behandling som många andra medier före det har jag valt ut fyra spel inom två olika genrer för en analys av deras handling, karaktärer, estetik och gameplay. Handlingen summeras enligt reglerna för narrativt berättande och en semiotisk infallsvinkel används sedan för att leta efter saker, tecken, som är värda att tas upp för analys i alla fyra kategorierna. Vissa jämförelser görs mellan spelen, främst inom kategorierna estetik och gameplay, först inom samma genre och sedan genrerna emellan för hitta likheter och skillnader i sättet spelutvecklarna har valt att utmana spelaren och göra spelen roliga att spela och hur de har valt att förmedla spelens handling. De utvalda spelen är Capcoms Devil May Cry 3: Dante?s Awakening, Sony Computer Entertainment Americas God of War, Konamis Metal Gear Solid 2: Sons of Liberty och Ubisofts Splinter Cell: Chaos Theory.
