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.

This is a study of the letters from His Majesty the King to the county governor of Gotland in 1735. In the Age of Liberty the king had limited power. Royal decisions were made with the Council of the Realm where the King only had the advantage of having two votes and a casting vote. Furthermore, the Council had to act according to the decisions of the Estates of Parliament, if at least three of the four Estates were in agreement. The duties of the county governor were set out in a detailed instruction of which the most recent version was issued in 1734.

   Did the mass media report in a different way about the real estate tax before the Swedish national election 2006 than they did after the election? If there were differences, what could be the cause?This study aims to answer these questions by using a quantitative analysis of articles about the real estate tax published in the Dagens Nyheter (DN), the biggest morning daily. The summer before the election, the ?Alliance?, (the non-socialist coalition, launched an election promise to abolish the real estate tax. Instead they planned to introduce a low community charge.The Alliance won the election and formed a government to implement their election promise. The analysis was made on all the published articles in DN that covered the real estate tax issue. In total there were 43 such articles. These where all published between the launch of the campaign promise until the electionday and a month before the proposal was launched 19/9 2007, until the proposal was implemented in 2008. The study results in three interesting conclusions.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

Studien har utförts på företaget Ericssons avdelning för strategiskt inköp och syftar till att utforma en inköpsportfölj som kan positionera maktbalansen mellan Ericsson och dess leverantörer. Undersökningen utförs på tre olika kategorier inom inköp; Hardware, Logistics och R&D Consultancy Services. Studien ger även förslag på strategier som kan appliceras för att flytta maktbalansen till en mer fördelaktig position. För att kunna utforma en maktpositioneringsmodell undersöker studiens författare vad som orsakar och kännetecknar makt i en kund- och leverantörsrelation, samt vilken påverkan de identifierade faktorerna tycks ha.Ericsson är ett globalt företag som är världsledande inom kommunikationsteknologi. Inköp av produkter och tjänster står för en ansenlig del av organisationens kostnader, varpå inköpsarbetet blir av stor betydelse.

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.

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.

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.
