För närvarande läses elmätare av en gång per år, detta leder till att kunders elräkning baseras på ett schablonbaserat belopp. Enligt riksdagens proposition 2002/03:85 skall dock alla elkunder, senast fr.o.m. 1 juli 2009, faktureras efter faktisk elförbrukning varje månad. Detta har lett till en stor marknad för fjärravlästa elmätare som nu är ett måste för att kunna utföra den tätare avläsning som krävs. E.ON ES Sverige AB som är beställare av detta examensarbetet har specialiserat sig på att installera, underhålla och läsa av fjärravlästa elmätare åt nätägare.

Öppen källkod är ett sätt för programutvecklare att distribuera verket tillsammans med dess källkod och göra det fritt läsligt och modifierbart. Denna studie analyserar och identifierar risker och möjligheter som kan uppkomma vid migration till och driftsättning av öppen källkod. Metoden som används är intervjuer med representanter från ett urval av Skaraborgs kommuners IT-avdelningar. Studien har visat indikationer på att både risker och möjligheter skulle kunna finnas. Riskerna ligger främst i att kommunerna bör vara medvetna om att alla roller inom en kommun är viktiga, medan möjligheterna ligger främst i att de indikerar medvetenhet om begränsningar i kunskap vilket är viktigt för en lyckad migration och driftsättning.

The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program.

SEM AB utvecklar och tillverkar tändstyrenheter för förbränningsmotorer, bland annat naturgas- och biogasmotorer. Tändstyrenheterna styr själva tändförloppet när de får en triggsignal från motorstyrsystemet (ECU). På grund av att enheterna används tillsammans med flera olika motorstyrsystem måste de anpassas for olika signaltyper och cylinderantal. Anpassningar av både mjukvaran och hårdvaran måste göras och detta kräver tid och resurser för utvecklarna på SEM.Syftet med detta arbete är att utveckla ett ingångsinterface till tändstyrenheterna som möjliggör att de kan anpassas på ett enklare sätt. För att minimera antalet komponenter i tändstyrenheterna ska även funktioner som realiseras med diskreta komponenter, om möjligt, integreras i ingångsinterfacet.En lämplig programmerbar krets för detta ändamål har valts.

The task for this thesis is to design a tool that is used to cut-out preforms of thermoplastic adhesive and also to make an estimate of costs for the stamping tool. The tool is used in the repair process at the MCM production line. The result of gathered information has affected how the design of the stamping tool has developed. The handling of thermoplastic adhesive in the repair process is one of the factors that influenced the design. The adhesive is sensitive for exposure to moisture. Therefore an automated feeding system of the adhesive is not recommended. The users wished for an automated stamping tool.

Alkolås är en teknik som gör att fordonet inte går att starta om föraren har alkohol i utandningsluftet. Vissa alkolås som hittills använts är utrustade med en minnensfunktion som regelbundet töms och bearbetas i ett särskillt pc-bearbetat dataprogram. Syftet med undersökningen var att utreda vart gränsen går till att kränka den personliga integriteten för att öka trafiksäkerheten med hjälp av alkolås, samt att utreda attityden till alkolås. Undersökningen är baserad på enkäter som besvarats av Luleå Lokaltrafik, Pitetaxi och Testplats Botnia. Ett problem med alkolås är att individen inte har kunskap om alkolåsets funktioner, och de integritetsproblem som kan uppkomma.

Det har blivit allt vanligare att vi idag använder våra mobila enheter till att besöka webben.

The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.
