Gradering av vindkraftslägen i Lerums kommun med hänsyn till infrastruktur och läge
The aim of this master thesis was to find and grade suitable sites for wind turbines in the rural district of Lerum at the reguest of Göteborg Energi. The rural district of Lerum consists of very complicated terrain which was the reason why we picked Lerum.The assignment was achieved by using the software program ArcGIS and its attendant tools. In step 1 an overall analysis was made in order to sort out the least suitable sites. Step 2 consisted of a 3D analysis in ArcScene together with a more precise analysis in ArcMap. As result we found two interesting sites, which met our demands and specific constraints.

AbstractTrendanalys av rapporterade störningar vid de svenskakärnkraftverkenAnalysis of trends in reported safety-related events atSwedish nuclear power plantsSafdar KargarThis degree project was conducted at the Swedish Radiation Safety Authority (SSM)as part of the bachelors program in Nuclear Engineering at Uppsala University duringthe spring of 2011.The Swedish Radiation Safety Authority (SSM) has developed a Windows baseddatabase called ?ASKEN? during later years. In this database more than 12 000 eventreports are stored sorted in three categories, category 1, 2 and 3. The databasecontains events from the start of Oskarshamn 1 in 1972 till present time.All nuclear power plants in Sweden are obliged to report any deficiency in theirbarriers and/or the defense in depth in obedience to SSMFS 2008:1.When a failure is detected or there is reasonable suspicion of a deficiency, the eventreport should be classified as a deficiency of category -1, 2 or 3 [1].The event reports are logged and archived in the register of SSM. The SSM task forceAnalys av Störningar på elproducerande Kärnkraftverk (the ASK-group), evaluates allincoming event reports and categorizes them according to established criteria.The aim of the project is to study and analyze the event reports in the database andidentity interesting observations and trends which should be investigated morethoroughly by deeper analysis to establish any positive or negative trends of reportedevents. .
Bearbetningsmaskin för fälgar i kolfiberkomposit
Detta examensarbete har utförts på uppdrag av Koenigsegg Automotive AB, som utvecklar, tillverkar och säljer högpresterande sportbilar. Företaget erbjuder fälgar tillverkade helt i kolfiberkomposit, som ger betydande viktbesparingar i jämförelse med traditionella metallfälgar.Efter tillverkningen kräver fälgarna viss bearbetning vid anläggningsytan mellan fälg och däck. Syftet med examensarbetet har varit att undersöka möjligheten att utföra bearbetningen av fälgarna in-house i Ängelholm, och målet har varit att konstruera en maskin för detta ändamål.Projektet inleddes med en litteratursökning, där svårigheter och möjligheter gällande bearbetning av kolfiberkompositer undersöktes. Till följd av de undersökningar som gjordes, valdes bearbetningsmetoden svarvfräsning och ett antal konstuktionskoncept genererades. Genom ett antal utvärderingar utvecklades ett speciellt koncept vidare till ett komplett produktförslag.Produktförslaget är komplett med analyser, beräkningar samt tillverkningsunderlag, som ger uppdragsgivaren bättre insikt i sina möjligheter.
Säker grannupptäck i IPv6
The IPv6 protocol offers with some new functions, one of them is auto configuration. With auto configuration it is possible for nodes, i.e. hosts and routers, for automatically associated with IPv6 addresses without manual configuration. Auto configuration it is another protocol as it uses Neighbor Discovery protocol (ND) messages (ND is mandatory in the IPv6 stack). The main purpose of ND is that nodes can discover other nodes on the local link, perform address resolution, check that addresses are unique, and check the reachability with active nodes.There are exactly the same vulnerabilities of IPv6 as IPv4 and is now exception, ND if not properly secured.
Something old, something new, something borrowed, something blue : A collaborative master thesis project exploring the development of Löfstrands Verkstad?s identity through physical artifacts, the contextualization of them and the system that provides the
Förord:Ämnet för mitt examensarbete var att arbeta med företagsidentitet genom att fläta samman ett specifikt företags (Löfstrands möbelrenoveringsverkstad) befintliga verksamhetsstruktur och ambition med planeringen och formgivningen av dess egenproducerade objekt.Löfstrands Verkstads vilja att skapa möbler som skall kunna ärvas vidare (likt de möbler de renovering i sin befintliga verksamhet) lades tillsammans med möjligheterna med småskalig produktion (i deras verkstad, samt kontaktnät) som grund till en verksamhetsbreddning för Löfstrands Verkstad i Hägersten.Den fysiskt manifesterade slutprodukten av examensarbetet är en möbelkollektion skapad för Löfstrands ideal, identitet, lager- och produktionsmöjligheter. En kollektion i vilken kunden bjuds in till medskapande (eller art directing) av möblerna för att knyta strarka band till dessa och verkstaden..
Informationskompetens i praktiken -en fallstudie av informationskompetens och lärande hos en grupp fordonselever
This master's thesis sets out to explore information literacy in a contextualized learning environment with emphasis on students at a vocationally oriented program in the Swedish upper secondary school. The concept of information literacy is widely discussed and furthermore a common subject for research within the field of Library and Information Science. Information literacy can be described as a set of skills or a range of attributes defining an information literate person. The skills and/or attributes facilitating the development of critical thinking and problem-solving skills are often linked to knowledge about computers and libraries.Another view on the concept of information literacy has been developed by the Australian researcher Annemaree Lloyd. She stresses the importance of social and physical information sources and that these also should be included in the development of information literacy.

Dagligvarumarknaden : en samhälls- och distributionsekonomisk analys av internet som försäljningskanal
Structural changes on the grocery market usually take place when the consumer is persuaded to take on the more labourintense parts of the distributionprocess. Internettrade changes this by causing competition between the unpaid work done by consumers and the labor performed by employees. In this master thesis grocery shopping on the internet is analyzed in a economic perspective with focus on distribution, changing marketstructures, driving forces and the future potential of internet as a saleschannel. The main conclusions are that consumerdemand and the belief in electronic commerceas a costreducing mechanism as well as a powerful new marketing tool were the driving forces behind the fast growth of grocery shopping on the internet. Electronic commerce introduces a new model of distribution with changing roles for consumers and grocerychains.
