At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..

This report will discuss principle, primary and finally manufacturing structure. We were asked to produce a 3D milling to processing the prototype material that is used on the University of Halmstad. From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Bakgrund Mäns våld mot kvinnor är ett globalt hälsoproblem, som spänner över såväl religiösa, geografiska som socioekonomiska gränser. En metod för att hitta dessa kvinnor är att administrera ett så kallat screeningverktyg eller frågeformulär. De tillgängliga verktygen är många och inget anses än vara vedertaget inom svensk hälso- och sjukvård.Syfte Att sammanställa en översikt av olika screeningverktyg som kan hjälpa sjuksköterskan att upptäcka mäns våld mot kvinnor.Metod Litteraturöversikt i form av en beskrivande sammanställning, baserad på tolv vetenskapliga artiklar av kvalitativ ansats.Resultat En sammanställning av sex screeninginstrument (ASI, HITS, PVS, STaT, WAST och WEB) presenteras. Frågeformulärens sensitivitet och specificitet redovisas, exempel på frågor samt styrkor och svagheter i formuläret beskrivs.Slutsats De sex beskrivna screeninginstrumenten har ett gemensamt syfte, att upptäcka våld. De skiljer sig åt i psykometriska egenskaper och är svåra att jämföra med varandra.

Hemp is an ancient cultivated plant that came to Sweden in the 1st to 2nd Century and was particularly interesting for use for food, clothing and building materials. Over time, other applications have been developed for hemp, e.g. in energy and health products. Interesting new uses for hemp continue to be identified and this fascinating plant has incredibly versatile applications.In this project, seed production of industrial hemp in Sweden was studied and evaluated. Five different methods are described, four of which are proven under Swedish conditions.

Bröstcancer är den vanligaste cancersjukdomen hos kvinnor men med rutinmässig mammografiscreening vartannat år och tidig samt effektiv behandling, har dödligheten minskats de senaste två decennierna. Orsakerna till varför vissa kvinnor får bröstcancer är inte klarlagda. Det kan bero på flera bidragande faktorer, bland annat arvsanlag. En del av den ärftliga bröstcancern beror på mutation av bröstcancergen1 (BRCA1) och bröstcancergen2 (BRCA2). Mutationsbärare tillhör en högriskgrupp och erbjuds därför årlig screening med magnetresonanstomografi (MRT), mammografi och ultraljud redan i ung ålder för att tidigt kunna upptäcka och behandla eventuell bröstcancer.

This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.

GPGPU is a collective term for research involving general computation on graphics cards. A modern graphics card typically provides more than ten times the computational power of an ordinary PC processor. This is a result of the high demands for speed and image quality in computer games.This thesis investigates the possibility of exploiting this computational power for image processing purposes. Three well known methods where implemented on a graphics card: FFT (Fast Fourier Transform), KLT (Kanade Lucas Tomasi point tracking) and the generation of scale pyramids. All algorithms where successfully implemented and they are tree to ten times faster than correspondning optimized CPU implementation..
