The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Citizens? freedom of choice has been a subject of debate in Sweden for over 30 years. This study focuses on decision making processes among patients within the Swedish healthcare system. The main conclusions are that in contrast to how patients? freedom of choice is described within governmental bills and governmental inquires and reports, patients are not following the steps included in the rational model of decision making.

This report describes a system for verification of fingerprints against a previous created template. It describes how and why a fingerprint image must be processed before it can be used to either identify or verify a person. The method is based on special features of a fingerprint, called minutiae points. The whole process from image to matching is described, every step in the process with image enhancement, binarization, thinning and how to find the minutiae points. Also what false minutiae points are, how they arise, why they deteriorate the result, and how to handle them, is discussed.

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.

Employees of the criminal correctional system have a duty to notify social services if they suspect that children are exposed to maltreatment, according to Chapter 14, § 1 SoL. Despite the obligation to report, studies show that this is not done at all times. The purpose of this paper is to describe and analyze how the criminal correctional system in Kalmar looks at notification if they suspect that children are exposed to maltreatment. To examine this, we used qualitative research method based on semi-structuring interviews; these were carried out with six employees, working in the criminal correctional system. The answers that emerged during the interviews have been analyzed using Yeheskel Hasenfeld theory of human services organizations, and trough previous research.

Då ett barn drabbas av en sjukdom som diabetes berör detta oftast hela familjen. Förändringar kan ske både i livsstil och kosthållning, men inte enbart för diabetikern utan även för den övriga familjen. Syftet med denna undersökning var att ta reda på hur matvanor såg ut i familjer där barnet hade typ 1 diabetes och hur kostbehandlingen av diabetes inverkade på familjen. Med vetskap om familjens matvanor undersöktes även om dessa skiljde sig från Medelsvenssons matvanor. För att genomföra undersökningen användes två kvantitativa metoder, enkät och matdagbok.

Datoranvändningen i samhället växer för varje dag. Det är då viktigt att programvara håller hög kvalité, då vissa programvaror styr kritiska maskiner som exempelvis flygplan. Ett sätt att få kvalitativa programvaror är att använda bra utvecklingsverktyg. I detta arbete utvärderas fem olika utvecklingsverktyg: GNAT (Ada), Microsoft Visual C++, Microsoft J++, Borland Delphi och Active Perl. Inriktningen på utvärderingen är mot utveckling av programvara för PLC-system.

I denna uppsats har det undersökts vilka användbarhetsproblem som är framträdande i HRutan, samt vilka förbättringar som kan härledas i HRutan avseende användbarhetsproblemen. HRutan är en samlingsplats för allmän självservice och information i anknytning till arbetet inom HR-området inom Malmö stad och används av anställda inom Malmö stad för arbetsrelaterade uppgifter. Undersökningen har gjorts genom att analysera ett utvalt HR-system med hänvisningar till utvalda designanvisningar och direktiv. Designanvisningarna och direktiven presenterades för den utvalda målgruppen genom en undersökning i form av intervjuer. Syftet med den första genomförda intervjun var att samla åsikter och synpunkter från målgruppen angående potentiella användbarhetsproblem i det utvalda HR-systemet.

Syftet med denna studie var att jämföra antalet anpassade utomhuslekplatser i Norrlands kommuner sedan 2001, och få svar på de ansvarigas uppfattning gällande tillgänglighet och anpassning, då tidigare studier visat på brister gällande dessa områden. Barn med funktionsnedsättning riskerar att uppleva social isolering och diskriminering om utomhuslekplatsers fysiska miljö skapar barriärer. Enligt funktionshinderpolitiken ska Sveriges allmänna platser och byggnader vara tillgängliga för alla år 2016. Metod: En enkätundersökning med mixad metod genomfördes där enkäter postades till de ansvariga för utomhuslekplatser i Norrlands 54 kommuner. Resultat: Resultatet jämfördes genomgående med en studie från 2001.

Idag är datorn en självklarhet i de flesta hem. Ökningen i användandet av datorspel hos barn väcker intresset över hur bra så kallade lärospel fungerar för yngre barn. De spel som finns idag är utvecklade för att passa normalstörda barn. Hur väl fungerar de för barn som har någon form av funktionshinder och då framförallt med inlärningssvårigheter? Autism är ett funktionshinder som bland annat innebär inlärningssvårigheter och svårigheter i kommunikation.

This essay takes the three models from Allison and Zelikow book Essence of decision and applies them on the Swedish defense system. After the cold war the Swedish defense system had to undergo changes to be a more modern defense and be able to defend Sweden against threats. To also be able to cooperate with other countries in peacekeeping operations the Swedish defense had to be reorganized. The solution was to change direction from a defense system that was organized for invasion to instead be a movable defense ready for any challenge in Sweden or abroad. This reorganization will be analyzed according to the three different models..

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.
