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.

Patrullerande poliser i Malmö har en varierande och oförutsägbar arbetsmiljö. När de kommer till händelser där de är osäkra på hur de ska agera kan de konsultera tryckt metodstödsmaterial. Dessa tryckta handböcker är ofta utdaterade och icke-standardiserade. Tillsammans med Polisen i Malmö har vi tagit fram ett förslag till hur en digital version av denna typ av material kan se ut, med förslag kring gränssnitt och informationsrepresentation, och en diskussion kring vilka potentiella konsekvenser ett mediebyte kan få för poliserna ute på fältet. För att ta fram dessa designförslag använde vi oss av ett antal interaktionsdesignmetoder. Dessa utvärderar och diskuterar vi, utifrån hur väl de fungerar inom en myndighet som Polisen, i kontexten patrullerande poliser i Malmö..

Den här studiens syfte är att analysera den svenska marknaden för centralstyrda digitala skärmar. Studien görs mot bakgrund av en liknande studie som genomfördes vid Handelshögskolan i Stockholm 2007, som bland annat visade att marknaden inte var mogen för det här mediet. Den här studien ämnar således utreda om man kan dra andra slutsatser om marknaden 2010 och ge förslag på implikationer utifrån nuvarande marknadssituation.Studien är av kvalitativ karaktär och bygger till stor del på intervjuer med ett antal utvalda leverantörer och köpare av digitala skyltar, som samtliga besitter stor kunskap om produkten och branschen.Marknaden för digital skyltning har haft en mycket intressant utveckling de senaste åren och växt kraftigt i rådande finanskris. Man kan se en ökad förståelse och kunskap för produkten hos köparna, vilket har lett till att de skillnader som fanns mellan köpare och säljare gällande kunskap om digital skyltning mer eller mindre har försvunnit. Idag bidrar istället köparna i stor omfattning till att skapa framtidens digitala skyltning.Man kan se hur produkten sträcker sig till allt fler användningsområden och integreras med andra tekniska produkter.

Abstrakt I detta arbete undersöks hur konceptet lek går att applicera på digitala spel och hur man presenterar ett fiktivt universum och de regler som definierar det universumet. Syftet med denna undersökning är att öka kvaliteten på digitala spel för spelare genom att öka förståelsen för hur sådana regler introduceras. Frågeställningen som ämnas att besvaras är ?hur kan man introducera realistiska, semi-realistiska och fiktiva regler i ett spel??. Undersökningen baseras delvis på analyser kring varför vissa introduktioner av regler ofta accepteras och andra inte, dels på utvärdering av en gestaltning och dels på tidigare forskning. Denna undersökning är indelad i två delar; en researchdel och en produktionsdel.

The objective of this report is to present a review of the studies which has been carried out up to days date concerning how temperature affects vegetables physiologically when it comes to their health inducing as well as quality reducing features. The essay therefore starts off with defining what is meant by the terms health promoting and quality reducing features. It then moves on to describe how different subspecies of Brassica oleracea, that is to say vegetables such as broccoli, cauliflower, Brussels sprouts and kale, is affected by temperature. B. oleracea was chosen because the species contains several commercially interesting subspecies and therefore provides a broad field even though only one species is assessed.
