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.

Today there are many system development projects that break both budget and time plan. Often this depends on defects in the Information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of Information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of Information systems.

This was achieved by creating an Android applicationwhich, along with a running server, continuously presents the user with all the currentneeded information. It uses the graphics engine andEngine to create the graphical userinterface. The application was created in the development environments Eclipse andAndroid Studio..

This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.

Problemställning: Det existerar idag en betydande forskning som berör digitala system för kunskapsöverföring. Emellertid ser vi en tydlig brist i forskningen kring användandet av de olika systemen. Detta beror till stor del på problemet med att kunna mäta att en medarbetare verkligen använder systemet för kunskapsöverföring. Genom att studera kunskapsutbytet i organisationerna hade det varit möjligt att kartlägga de områden som påverkar användningen av digitala system för kunskapsöverföring. Frågeställning: Vilka faktorer påverkar användningen av digitala system för kunskapsöverföring? Syfte: Syftet är att skapa en modell som visar de faktorer som påverkar användningen av digitala system för kunskapsöverföring, samt att genomföra en första prövning av modellens giltighet genom en studie av tre företag.

Vid design av IT-system krävs en förhållning till de specifika egenskaper som finns i den miljösystemet är tänkt att användas. Även om användningen ser liknande ut krävs en detaljeradanalys av det specifika sammanhanget för att få en djupare förståelse för hur det verkligaanvändningsområdet ser ut. Det har visats sig uppkomma användbarhetsrelaterade problem vidförflyttning av ett system från en stationär miljö till en mobil miljö. Rapporten har undersöktvilka utmaningar som uppkommer när ett system flyttas från en mobil miljö till en annan snarlikmobil miljö och tar sin utgångspunkt i Ecodriving-lösningar för tunga fordon. En kvalitativundersökning genomfördes för att undersöka och identifiera de utmaningar som uppkom.Analyserat material låg till grund för framtagningen av en prototyp.

Kraven på dagens trådlösa förbindelser kommer hela tiden att öka och med detta följer även högre krav på nya produkter som kan tillgodose de ökade kraven. För att göra processen från idé till produkt snabbare krävs enkla verktyg för att snabbt kunna gå från den formulerade standarden till en hårdvaruprototyp. Detta arbete har använt sig av ett av dessa verktyg som idag finns tillgängliga, Xilinx System Generator for DSP 1.1, för att ta fram sändare och mottagare för en del av den trådlösa standarden IEEE 802.11a. Arbetet ger en beskrivning av hur sändare och mottagare är uppbyggda samt även synpunkter på System Generator och beskrivningar av problem som uppstod under arbetet.

Deontic Action Logic Multi Agent System (DALMAS) är en typ avmultiagentsystem där agenternas handlingar regleras av ett normativt system. Teorinför DALMAS bygger på deontisk logik, och normer i det normativa systemetuttrycks i termer av Kanger-Lindahls teori om normativa positioner. Syftet meddetta arbete är att försöka reda ut vilka eventuella fördelar ett normativt system kange samt hur man ska kunna skapa effektivt sådant. Går det att skapa ett normsystemsom kan lösa samma problem som ett konventionellt MAS löser? För att kunnajämföra de olika normsystemen har kriterier för hög effektivitet tagits fram.Testresultaten visar bl.a.

Migration mellan system används oftast när ett system har blivit föråldrat och då det märks att det inte längre är lika effektivt gentemot nyfunnen teknik. Då är det därför intressant att använda sig av migration, när det är av intresse att skapa ett nyare system utifrån det gamla. Detta arbete går igenom och löser problem vilka uppstått när en migration mellan ett dokumenthanteringssystem till en webbapplikation görs. Men fokuseringen har riktats mot att hitta den bästa migrations och övergångsmetoden för att kunna skapa en bra, enkel och effektiv migration mellan ett dokumenthanteringssystem till en webbapplikation.
