Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Användningen av Internet och antalet nya tjänster ökar mer och mer. Internet är ett öppet system och för att Internet i högre utsträckning skall kunna användas även vid hantering av känslig information krävs bättre säkerhet. Syftet med denna rapport är att utifrån Karlskrona kommuns säkerhetspolicy samt medborgarnas åsikter om säkerhet, undersöka vilken eller vilka säkerhetslösningar som lämpar sig bäst vid den planerade 24-timmarsmyndigheten. I denna rapport undersöks vilken eller vilka av de alternativa medborgarcertifikat som myndigheter får använda sig av. Målet är att komma fram till en möjlig lösning för elektronisk identifiering inom den framtida, 24-timmarsmyndigheten inom Karlskrona kommun.

This study is an analysis of the Internet transaction logs of Malmö Public, Sweden [...].

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

Internet har i över 20 år påverkat samhällets förutsättningar, så även skolans arbetssätt och undervisningssituation. Förändringarna i samhällssektorn avspeglar sig inte minst i samhällskunskapsämnet både gällande innehåll, administration och kommunikation. Satsningarna på internet som praktiskt redskap har varit stora men information om dess teoretiska aspekter har lyst med sin frånvaro. Därav arbetets relevans där syftet har varit att undersöka på vilket sätt gymnasielärare i samhällskunskap beskriver internets påverkan på samhället och hur de undervisar om detta. Fyra kvalitativa intervjuer har gjorts, vilka samtliga har varit semistrukturerade för att kunna besvara arbetets syfte.Arbetets resultat har varit att det funnits stora privata skillnader i användande hos de intervjuade lärarna.

This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.

Blogpics ? young girls views on photography online Young people create new forms of social interaction on the internet, and in Sweden, especially young girls, have become very active bloggers. Girls write, publish pictures and build networks with, mostly, other girls.  This new phenonomen has been described in Swedish media partly as a problem, where adults are worried that the information the young girls publish about themselves is too personal, and can be used for the wrong purposes. It has also been suggested that the content of young girls blogs has little value, beeing mostly narcissitic, superficial and obsessed with fashion and shopping. The purpose of this paper has been to investigate how young girls reflect upon their photographic communication on the internet.  The idea has been to ask the girls themselves about their own experiences, to get a more complete picture of them as internet users, to investigate their communication strategies and solutions when it comes to net integrity  and to talk about how they create gender and identity online..

Purpose/Aim: The aim is to examine the cooperation between the magazine Veckorevyn and its Internet based counterpart, veckorevyn.com. The purpose is also to see if veckorevyn.com is taking advantage of Internet and its possibilities.Material/Method: There are two qualitative methods used for this study: interviews and a three-pieced content analysis. The material analyzed is the magazine Veckorevyn (number 25/2008) and the website www.veckorevyn.com during a two week period.Main results: The study shows that Veckorevyn and veckorevyn.com have several differences, but also some similarities. The result is not unexpected, since we are dealing with two different types of media. There seems to be some cooperation, though on the web it is not very visible.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

This paper discuss the possibilities to improve the Swedish political nomination system. It brings up some of the values and norms that can be used to change the existing system. Values as openness, the demand of responsibility and also if there is values from the American spoils system that can be used in the Swedish system. A minor purpose is to discuss the part of the parliament within the nomination process. To investigate this I have some theoretical starting points and a self constructed analysis tool.

Denna uppsats har skrivits för att visa läsaren hur ett urval av människor från Internet- och reklambranschen ser på reklamfilmens framtid på Internet. Kommer det att ske en ökning av användandet av denna reklamform eller inte? Den typ av reklamfilm som vi talar om här är den typen som är som en kortfilm, inte den typen av reklamfilm som bara är en bild innehållandes ett rörligt objekt. För att skilja dessa två typer av reklamfilmer åt, eftersom båda innehåller rörelse, kallar vi dem "filmisk reklam" och "banner-reklam" Resultatet från enkätundersökningen visade att majoriteten av urvalet från reklambranschen tror att det kommer att ske en ökning av efterfrågan av filmisk reklam på Internet. Eftersom svaren från Internetbranschen var så få kan de inte representera Internetbranschen.

The purpose of this report is to answer the question:How do you create a media player that can stream music for a website?We started the work by searching the web and reading books about the subjectand found several technologies to use to stream media files over the internet.We decided upon using the http protocol and created the media player itself inMacromedia Flash.The website is mostly developed with PHP, JavaScript and CSS templates andthe websites design was created with Macromedia Dreamweaver and AdobePhotoshop. We also created an administrative system for the media player withPHP programming.The website contains a simple guestbook; the guestbook makes use of adatabase created with MySQL.Our work resulted in a webpage with a fully functional media player thatstreams audio files together with a corresponding administrative system for it..

I detta examensarbete har en studie av svenska små och medelstora företag som genomfört en satsning på Internet genomförts. Studien hade till syfte att undersöka vilka resonemang som föregått olika företags satsning på Internet och huruvida företagen uppfyllt sina målsättningar med sin satsning.För att skaffa mig en bättre överblick av problemet och för att kunna definiera problemställningen, så studerades tillgänglig litteratur och tillämplig information inhämtades från Internet. För att sedan besvara problemet och de problemställningar som identifieras i kapitel 3 så genomfördes två intervjuomgångar med olika inriktningar. Den ena intervjudelen inriktades mot reklambyråer som skapar WWW-platser åt andra företag. Den andra intervjudelen genomfördes med svenska små och medelstora företag som etablerat närvaro på Internet.En del av slutsatserna består av att företagen inte planerar speciellt mycket innan de påbörjar processen med att etablera närvaro på Internet och att det kanske till viss del beror på att företagen ser det som en relativt låg kostnad för en Internetsatsning, jämfört med andra typer av marknadsföringskostnader.
