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.

Denna rapport redovisar för utvecklingen av mobilapplikationen Uppgångsappen. Applikationen, som har utvecklats för iPhone, skapades för att kunna ges ut av företaget Approdites AB. För utvecklingen har Apples riktlinjer följts både för design och programmering, och fokus har legat på att utveckla en applikation som uppfyller Apples krav för att bli godkänd i AppStore. Programmeringsspråket Objective-­C har använts tillsammans med utvecklingsmiljön xCode. Designbeslut har grundats på designprinciper och målet har framförallt varit att utveckla en applikation som ska vara lätt att använda och ha en estetiskt tilltalande grafisk design.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

Användningen av Internet har ökat kraftigt de senaste åren och begreppet webbportal har blivit allt vanligare. Syftet med det här arbetet är att undersöka om det är en webbportals design som är det avgörande vid valet av webbportal eller om det är innehållet och tjänsterna. Kanske är det en kombination av design och tjänster som värdesätts högst.I detta arbete utförs en heuristisk utvärdering av ett antal bostadsförvaltningsportaler för att undersöka både eventuella användbarhetsproblem samt hur väl designade portalerna är. I arbetet görs även en enkätundersökning hos ett antal utvalda hyresgäster hos AB Skövdebostäder för att undersöka inställningen till designen av företagets webbplats samt dess innehåll och tjänster.Resultatet visar att webbportalers tjänster är viktigare än designen men att designen inte är helt oviktig. Några generella slutsatser kan dock inte dras av detta arbetes undersökningar eftersom både antalet medverkande portaler och hyresgäster är allt för få..

In this thesis I will propose and test a pipeline for creating in-game animations using motion capture technology, with the aim to export to a 3D game engine, such as UDK or similar. Even though there are already established pipelines for creating in-game animations in the game industry, they are not of public knowledge and dissemination of information is hindered by the severe NDA (non-disclosure agreements) imposed on the studios and artists. I will therefore use my experience with game production and as a student, to research and propose an optimal pipeline for developing in-game animation that may be used by other students, researchers and independent game developers. The methodology used to test the pipeline will be a case study based on the student project Synergy, which I am developing with other third year students also attending the Game design Education at Gotland University..

The transformed municipality ? Economic and social growth in Örnsköldsvik 1997-2007Author: Kristina HanssonThis thesis focuses on the economic and social growth in the municipality of Örnsköldsvik. It is a single case study and the municipality is studied through economic theories concerning regional growth in the period of 1997-2007. The aim is to analyse whether these theories, such as Åke E. Anderssons and Ulf Strömquists K-society, and other more or less microeconomic assumptions, also are applicable in smaller local contexts.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

This Master Thesis is a product development project that has been carried out in cooperation withSvea Teknik AB. The company has developed an apparatus for attachment of a keel to a hull base ofa boat. The purpose for this thesis has been to compare a new concept of keel attachment incomposite material to thetraditionaldesign solution. This new keel attachment minimizes thedamages that may arise on the keel and the hull of the boat in shape of stresses impacts at grounding.Today it is a problem, relating to keel attachment on sailing boats having a fin keel or a bulbous keel.The manufacture focus on developing larger draught and shorter keel blades. The overall purpose isto increase performance of the sailing boat.The task for this thesis was to develop a concept of keel blade in composite material and investigateattachment to a sheet-shaped element.

Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.
