Denna examensrapport redogör för hur man kan få en kortslutningsskyddadoch säker inkoppling av en DC-länk mellan två skiljda elektriska system.Rapporten bygger på hur en lastbil ska kunna få en större säkerhet för attbibehålla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem består idag av två skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingår två stycken elektriskabromsar i varje system. Om det tex blir fel på en av bromsarna och dennapåverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill även kunna försörja den fungerande bromsen somsitter i samma system via en så kallad Axle Link. Denna strömmatningslänksitter mellan två hjulpar på samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch säker DC-överföring via en Axle Link, i första hand med diskretakomponenter.

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

This paper aims to investigate how Helsingborg?s city library?s visi-tors feel about computer games being available for lending and in which way computer gamers see Helsingborg?s city library as a resource. This was examined first with a study of 100 of the library?s visitors and then with five interviews with computer gamers and an interview with the librarian responsible for purchasing games.The study showed that most visitors were neutral to having games at the library and of the ones that were not neutral many more were positive than negative. Of the five gamers who were inter-viewed, there were several who had borrowed games in the past.

The aim of this study has been to investigate whether people with siblings that have disability have been personally affected when making choices about their studies and careers based on their upbringing with their siblings. The method chosen was qualitative data and consists of six interviews with people who are familiar with the chosen problem area. In conclusion, our results do not show a link between choices of study in relation to the sibling's disabilities. However a link was found between career choices, many choose to work in the area of health and well-being. This link was also found in literature we have researched, people living with disabled siblings have chosen careers and jobs within health and well-being..

The Swedish tax on income for persons who are unlimited liable to tax is based on his domicile and double taxation treaties between Sweden and other countries are based on his residence. In order to determine a person?s tax liability, the dwelling or home is of vital importance to determine where a person has his domicile and residence.For a person who has moved from Sweden, to be unlimited tax liable here, there must be an essential link. This link can be through previous residence in Sweden, the person is not a permanent residence in a foreign country, in possession of housing for year-around-use or in possession of house property.Sweden has concluded double tax agreements with other countries for the reason to prevent double taxation on the same income. When a taxpayer may be regarded as a resident in two states, the situation must be resolved to avoid that double taxation will arise.

The aim of this paper is to investigate who the visitors are at a children's department at amain library in a larger municipality, and for what purpose they use it. We discuss: Is therea difference between various user groups, and if so, how do they differ'? Which library rolesdoes the children's department have? Does the children's department serve as a local libraryfor those who live in the immediate surroundings or as a main library for the whole municipality?The paper is based on a user survey performed in the spring of 1996 at the City Library ofGothenburg. 417 visitors and five staff members were interviewed.The children's department is used by various groups of people, from young children to seniorcitizens. The library roles are, among other things, an independent learning center and formaleducation support center.

The purpose of this Master?s thesis is to examine and analyze the discourse concerning a new public library in Stockholm. The paper further discusses how this discourse corresponds with what is written about public libraries in a number of national and international documents. To do this I have utilized the discourse theory of Laclau and Mouffe. By using some of their instruments I have established the discourse around a number of keywords.

This paper describes the development of direct and indirect service at the former Gothen­burg city library. This was during this period of time not the public library of the town, but a scientific library mostly serving the college, although also open to the public. Furthermore the services offered in Gothenburg are compared with those of the two old Swedish university libraries in Uppsala and Lund. The investigated direct serviceforms are "making material available", "guidance", and "localities". The indirect service areas are "the catalogue" and "the personnel and their competence".The conclusion is that the differences weren't that big and that Gothenburg city library was a modern library providing about the same services as you could find in Uppsala and Lund.

TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.

Har ni någon bra kärleksroman? : en studie av indexering av skönlitteratur vid stadsbiblioteken i Malmö och Mölndal. Have you got a good love story? : a study of fiction indexing at the public libraries of Malmö and Mölndal.The thesis analyses interviews with users of two Swedish public libraries to find aspectsof fiction important to users and consequently to be considered when indexing fiction.Descriptions of a novel by 50 users at each library are compared to the index terms usedfor these novels. For the analysis, the authors propose a model of their own based onAnnelise Mark Pejtesen's AMP system for fiction indexing.

Jag har utvärderat Umeåregionens bibliotekssamarbete. Samarbetet innebär att biblioteken i kommunerna Bjurholm, Nordmaling, Robertsfors, Umeå, Vindeln och Vännäs har en gemensam bibliotekskatalog och att låntagare har ett lånekort som gäller för hela regionen. Låntagare kan låna och lämna tillbaka media på samtliga bibliotek i regionen.                                                                                          Syftet med utvärderingen är att kartlägga låneflödena mellan biblioteken i regionen för att få kunskap för att utveckla medieförsörjningsstrategier och ?metoder på biblioteken. Utvärderingen innehåller en översiktlig kartläggning av låneströmmarna i hela regionen samt en mer detaljerad kartläggning av låneströmmarna mellan Umeå stadsbibliotek och Ålidhemsbiblioteket (Umeå kommun).

Denna uppsats är resultatet av en undersökning av två kulturevenemang, Kulturnatten i Norrköping och City Art Link i Linköping. År 2009 arrangerades dessa kulturevenemang med en veckas mellanrum och visar vad respektive stad har att erbjuda inom kulur. Vi ville undersöka hur dessa evenemang skiljer sig åt och hur de används som marknadsföringsverktyg för de aktörer som deltar i evenemangen och även för städerna.Syftet med denna undersökning är att undersöka och analysera på vilket sätt två kulturevenemang i två städer kan skilja sig åt. De evenemang vi kommer att undersöka är Kulturnatten i Norrköping och City Art Link i Linköping. Vi kommer genom intervjuer att undersöka hur evenemangen fungerar och används.

This thesis investigates how Ericsson AB should do to achieve fast and secure handover when roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. The premise was that they wanted a standardized way of handling the roaming issue. At the outset the 802.11F standard looked like a good alternative (in fact the only standardized alternative).
