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.

The purpose of this thesis is to compare mass digitization and qualitative digitization, to see how the digitization process and the digitalized material differ. The study emanates from the mass digitization as it is performed at the National Library in Norway, and the qualitative digitization at the Royal Library in Sweden. The method used is document studies combined with mail interviews. The focus is upon the practical operation, to which counts: ?purpose & selection?, ?preparation, image capturing and processing?, ?metadata & text encoding?, ?quality assessment?, ?storage of digital originals and copies? and ?display?.

The accounting of today results in reports that are valued according to one kind of value.There are advocates who recommend that the accounting should be expanded by one orseveral columns, which would enable that other methods of valuation could be used. In thisessay we examine how the ?multi column reporting? can alter the outcome of a financialanalysts? valuation procedure.In this essay we used existing theories about the financial analysts? usage of information toreach the lack of information we found and which we aim to erase whit this essay. To do thiswe studied decision theories and theories regarding information processing, and by interviewswith three financial analysts. After we collected the information needed for the analyses, wethen also compared the results of the interviews with related theories.The theories about decision in this essay concern whether a decision is based on rationality,bounded rationality or irrationality.

Den här C-uppsatsen utforskar möjligheterna att utforma applikationer till interaktiva plattformar som lär barn att lösa abstrakta problem och samtidigt är användbara för lärare i skolmiljö. Uppsatsen presenterar olika teorier och använder sedan det insamlade materialet som utgångspunkt för att testa om och hur dessa teorier kan tillämpas i ett specifikt fall. Resultatet sammanställs i form av en prototyp som testas på en klass förstaårselever i Stockholm..

The project was intended to produce a brush simulation plugin to the image processing program GIMP which would use a 6DOF drawing tablet for user input.Too ambitious goals coupled with compability issues between the resources used resulted in that no meaningful software was produced. Experience was however obtained, and this paper is intended to give an overview of relevant concepts for- and the process ofcreating a brush simulation..

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

Volvo Human Monitoring (VHM) är ett pågående projekt på Volvo Personvagnar där dem bland annat mäter in- och utandning genom en mätutrustning, kallad respiratorisk induktans pletysmograf (RIP), som mäter förändringar av tvärsnittsarean av bröstkorg och buk. När föraren är i rörelse till exempel när hon svänger ändras tvärsnittsarean och en ?störning? i RIP-signalen kan uppkomma.Dessa störningar medför att vid analys av RIP-signalen måste stora manuella justeringar utföras, vilket är mycket tidskrävande, och utrustningens validitet för mätning av in- och utandning ifrågasätts.Syftet med denna studie var att effektivisera analysen av en RIP-signal som registrerats vid bilkörning. Målsättningen var att skapa ett nytt databearbetningsverktyg i Matlab som på ett automatiskt sätt kan detektera in- och utandning från en RIP-signal med högre validitet än det existerande databearbetningsverktyget.I studien utfördes tester på nio förare under bilkörning på landsväg, grusväg, motorväg och i stadstrafik. In- och utandning mättes med en RIP, en pneumotakograf med en tätt sluten ansiktsmask och ett termoelement som var placerad mellan näsa och mun som referensutrustning.Resultatet blev ett databearbetningsverktyg som automatiskt detekterar in- och utandning med högre validitet än det tidigare internutvecklade databearbetningsverktyg.
