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.

Can the lack of functional cross-cultural communication among individuals within an international organization be the reason for cultural clashes to occur, and lead to conflict between two cultures within the same organization?Our aim is to try to create a potential model of how cross-cultural problems can be studied, in order to contribute to the solution of the problem. And to examine whether the theories, which form the basis of our model can be applied in reality.The research have assumed from the hermeneutical approach for a holistic view of the problem area. The deductive approach has been used in order to distinguish whether the theories can be applied to reality, and qualitative research method for collecting data.The focus lies within cross-cultural communications, which defines the various cultural factors that can affect organizational culture. Hofstede dimensions and the social structure are mentioned and cultural factors as language and religion.

International research has shown that through the involvement of the school library and the school librarian in the daily school work with the pupils, the pupil´s learning can be increased and reading comprehensions significantly improved.One purpose of this master`s thesis is to study the school librarian as a brand, representing the school library as well as the school librarian and whether there is a correlation between different comprehensions of the professional role of the school librarian. This is done by examining whether there is a difference between a specific librarian´s own perception of their professional role, compared to the image of the school librarian among teachers and principals working in the same school district and by comparing the profile the school librarian expresses with the image that is conveyed through communications via webpage, written and oral information given on services and competences provided by the school librarian and work carried out by her.A difference of comprehension of the school librarian´s competence and work, could be part of an explanation as to why the correlation between the involvement of school librarians in the school work and the improved learning achievements of the pupils has not resulted in the expected measures, regardless of the investments in school librarians and school libraries. The school librarians´ school identity could be difficult to establish. Whether or not the profiles and images of the professional role are consistent with each other is a much more manageable purpose which could go a long way of explaining the circumstances of the school libraries.That is the reason why we have examined whether the comprehension the school librarians have of themselves corresponds with the idea/ conception/ image conveyed to their surroundings, and with the idea/conception/image encompassed by people in their immediate surroundings..

Environmental issues and sustainable development is a high priority in today?s society and has received substantial attention lately. In the inaugural speech it is expressed that the goal for the IT?politics is a sustainable information society for everyone, which can be achieved by using IT to support sustainable growth. The Ministry of Enterprise, Energy and Communications has developed a document which outlines three specific proposals on what the government should focus on during a three?year period (2008?2010) that with the use of IT will contribute to a sustainable society.

Ronneby flygplats är en flottiljflygplats som ägs och drivs av försvarsmakten och som är öppen för civil trafik. Flygplatsen är lokaliserad i Kallinge strax norr om Ronneby tätort i Blekinge län. Flygplatsens tillgänglighet med allmänna kommunikationer är idag begränsade. Syftet med studien har varit att analysera och karaktärisera Ronneby flygstationsområde samt bidra med förbättringsförslag till hur flygplatsens tillgänglighet kan öka. Analyser har genomförts för att försöka ge en god helhetsbild av planområdet och dess omgivning samt de olika faktorer som spelar in.

This thesis will describe the redesign of the manure fork SverigeGrepen. The productis available for purchase in Scandinavia and and parts of the rest of Europe.The product is available in stores but the companys goal is to start distribute it overthe internet. A problem today with a purchase over the internet is that the costumerhas to pay a high shipping-fee due to the products unique form. The long handlecontributes to the high shipping-fee which makes it hard to attract costumers topurchase the product online. Deficiencies have been found at the manure forks basketand needs to be examined.

This thesis aims to explore the use of costumed interpreters at museums. Firstly the thesis examines how extensivethe use of historical costumes is in Sweden, along with some international comparisons. Later on the differentways that the clothes are used is examined, and the costume as a resource for learning is discussed. In the lastpart of the thesis the ?function? of the costume is examined.

The theory of deliberative democracy believes in collective decision-making to achieve an expanded legitimacy and rationality in the political process. It is argued that those good public dialogues best take places in public spheres between citizens, where the common interest is carefully thought about. This thesis was done with the assumption that theatre can strengthen the idea of the public sphere and create a meeting place in the civil society, where a good public dialogue can appear. To create a good public dialogue you need citizens that are corresponding and participatory. Citizens who participate in the political process develop an increased knowledge about the society and the more knowledge about the society the larger reason to participate.

Användandet av trådlösa nätverk ökar med rask takt och blir allt vanligare. Enligt en artikel i Computer Sweden kommer de trådlösa näten att ha 20 miljoner användare om 4 år. Analysföretaget Gartner Group har nyligen gjort en undersökning bland företag, vars syfte var att ta reda på hur stort intresset var för WLAN. Resultatet visade att 50% av företagen funderar på att köpa och installera WLAN-lösningar (Planet Wireless september 2001). Syftet med detta arbete var att beskriva hur den inbyggda krypteringsfunktionen WEP som för Wired Equivalent Privacy fungerar och hur säker den är, dvs hur lätt man kan knäcka krypteringen. Följande frågeställningar har besvarats genom litteraturstudier och ett praktiskt försök: Hur är trådlösa nät uppbyggda? Hur fungerar den inbyggda krypteringen WEP och hur säker är den? Vad kan man göra förutom att använda sig av WEP för att skydda sig mot avlyssning/intrång? Det praktiska försöket bestod av att knäcka WEP-krypterade filer med hjälp av programmet WEPCrack.

När en stad växer måste man ta ställning till hur det ska ske. Idag är biltrafiken dominerande i Göteborg och i framtiden skulle spårbunden trafik och utbyggd pendeltågstrafik i regionen kunna innebära mer hållbara tranporter. En pendeltågsstation har ett relativt begränsat omland och behöver för fullt utnyttjande bebyggas nära inpå. Den spårbundna trafiken kan dock innebära störningar och risker. Jag undersöker i mitt examensarbete hur en ny stadsdel utanför Göteborg kan byggas ut kring en tänkt pendel­tågs­station.

Arbetets utgångspunkt är att ta reda på vilka effekter en ny infrastruktur kan få på en kommun och på ett samhälle i kommunen samt vilka fysiska åtgärder berörda aktörer avser vidtaga på grund av satsningen. Jag har använt mig av Ale kommun som exempel när jag studerat. Jag har gjort en fallstudie över två liknande områden, som också påverkats av ny infrastruktur. Därefter har jag analyserat och diskuterat om man kan se några samband kommunerna emellan. Det jag har kommit fram till är lite olika.

Mellan 1960 och 1970 lades många järnvägssträckor ner sin verksamhet i Sverige, spåren revs upp och bilen tog över vår vardags pendling på allvar. Nu när effekterna av bilens framfart blivit kända är tåget åter ett intressant alternativ och olika gamla tågsträckningar vill återupplivas. Simrishamnsbanan är en sådan tågsträcka och är tänkta att åter förena de orter som finns mellan Malmö och Simrishamn. Veberöd är en av de orter som ligger utmed den forna tågsträckan och orten ingår i Lundskommun och mitt syfte med detta examensarbete är att finna svar på hur Veberöd ur ett ekonomiskat, socialt och ekologiskt "hållbart" sätt ska kunna anpassa sig till ett stationsnära läge, med tyngdpunkt på: Bostadsstruktur, Infrastruktur och Grönstruktur. Detta utifrån ett scenario där Simrishamnsbanan realiseras. Examensarbetet börjar med att problematisera hållbarhetsbegreppet och begrepp som täthet och gleshet, därefter följer en omfattande analys av Veberöds historia, bostadsområden, grönstruktur, verksamhet och service.
