Problem med att få besiktningsanmärkningar åtgärdade. Felaktiga inställningar och attityder fördyrar våra byggprojekt
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.

Digital reklamskylt för utomhusbruk, där ett dynamiskt målgruppsanpassat budskap ändras genom fjärrstyrning
The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Analys av mellanspänningsnätet i centrala delar av Västerås stad
The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.
Fräsch och strukturerad med attityd : Ett examensprojekt om tidningslayout
AbstractPresentation of the problem: The goal with this graduation project is to produce a new visual concept for the student newspaper Campus, this will be expressed in the form of page templates. The page templates will have a visual concept that appears through graphical elements. The client's wishes were that the student newspaper should be audience appropriate, attractive, inviting, reliable, modern and functional to work with.Theory: In order to implement the wishes and in a good way produce a consistent visual concept, we took a starting point in theory of graphic design. This theory has taken many of its principles from aesthetic theory, and therefore have we also used aesthetics to provide a deeper theoretical aspect. The principles we used in graphic design is; how to create a unity in the layout by using basic elements such as text, images, and white space.

Moderbolagsperspektiv kontra enhetsperspektiv : - motiv och konsekvens i teori och praktik
Abstract The development towards an international accounting standard implies that Swedish groups of companies that are not quoted on the stock exchange can use a parent company perspective or an entity perspective while making their group accounting. The purpose of this study is to describe and explain the motives behind the groups of companies choice of perspective and to show how these motives agrees with the effect it has on the profit and loss account and on the balance sheet.The study includes four fictitious groups of companies based on real groups of companies. Every group of companies includes 1-3 subsidiary companies, where at least one is owned by the parent company with 51-70 %. Some assumptions were made before the consolidation.Relevant key numbers have been calculated according to both perspectives and then compared. A total of three semi structured interviews have been carried out two with representatives for the real groups of companies and one with a chartered accountant.

Hur skildras judar och judendom? En textanalys av svenska medier
In my study, I aim to examine how the printed Swedish media depicts Jews and Judaism.How the agenda is for the depiction of Jews and Judaism and how it can be related todidactic challenges within the school subject religion. The study is based on 194 articlesfrom the Swedish newspapers, Dagens Nyheter and Svenska Dagbladet, in July and August 2014. I use a qualitative and a quantitative text analysis where I put articles in different categories. The study?s theoretical framework is The Agenda-Setting Theory and my study leans against Bachner (2006), von Brömssen (2012) and Revell's (2010) thoughts on the media having great influence over our image of religion and religious groups.My study shows, among other things, that Jews and Judaism are mainly mentioned in the media in relation to the conflict in Israel and Palestine, World War II or anti-Semitism.
Viktiga faktorer vid lantbrukares val av bank
The bank market for farmers in Sweden is dominated by Swedbank and Landshypotek. One of the most aggressive challengers is Länsförsäkringar Bank, which in 2009 had seven per cent of the Swedish bank market for farmers, but 57 per cent of all new lending. This paper deals with the problem of new banks to break into the bank market where farmers are slow in terms of change in their attitudes and loyal to their banks. The study has been carried out in cooperation with Länsförsäkringar Gävleborg which is a new actor in the banking market and thus eager to take part in the outcome of the study. This essay thus seeks to examine the attitudes farmers have against bank switching and the factors that influence their choice of bank.
?Förhoppningsvis är man två? : En studie över hur 18-åringar i en mindre stad i Sverige resonerar kring kön, kropp och sexualitet
The essay is about how teenagers around 18 years of age in a small town in Sweden talk about gender, body and sexuality. The study is based on two focus group interviews with five boys and four girls. We have then thematized and analyzed the material with queer theory.The results show how young people see heterosexuality as something 'natural' and gender as biologically determined. The teenagers are critical towards anything that deviates from the traditional nuclear family consisting of mother, father and children. Norms are created in their speech as some of them acts as so called "border guards" for these norms.
