Sammanfattning Fel i programvara (buggar) kostar ofantliga summor varje år. I detta arbete presenteras en metod där programexekveringsmiljön utan vare sig programmerarens eller användarens inblandning utförligt kan rapportera och dölja effekterna av en avsevärd andel buggar. Genom att kompilatorn eller tolken tillåter att en och samma procedur implementeras hur många gånger som helst införs ett helt automatiskt stöd för N-Version Programming (NVP) omedelbart i programspråket. Tekniken gör programvaran feltolerant och blir ett komplement till kostsam och ofta bristfällig testning. En tolk utvecklades för ett programspråk som tillåter multipla definitioner av procedurer. Därmed har det inbyggt stöd för feltolerans genom redundans på procedurnivå. Ett experiment genomfördes där nio programmerare oberoende av varandra implementerade 12 utförligt specificerade procedurer.

Det här projektet omfattar utvecklingen och designen av en webbplats och en webbcommunity för organisationen Nätverket Vileda samt implementationen av ett content management system för att underhålla webbplatsen. Jag reflekterar också kring Nätverket Vileda och nätverket som ett socialt fenomen men även som en kommunikationskanal för organisationer och hur detta har förändrats och utvecklats genom de senaste hundra åren..

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Allteftersom forskningen inom Human Computer interaction (HCI) fortskrider konstrueras det allt fler innovativa sätt att interagera med spelkonsoller. Då fler sätt att interagera med spelkonsoller utvecklas förbättras även förutsättningarna för spelbranschen att öka interaktionen i spelen. Den senaste generationen av spelkonsoller har kommit fram med egna lösningar och innovativa sätt att öka spelupplevelsen och interaktionen. Nintendo Wii har t.ex. en rörelsesensor som reagerar på rörelserna av handkontrollen, och Xbox Kinect reagerar med hjälp av en kamera som läser av kroppens rörelser och Playstation Move reagerar på en kombination av en kamera och en kontroll med sensorer. Handkontrollens design har inte förändrats mycket under de senaste konsol-generationerna om man bortser från Nintendo Wii som formade sin kontroll som en stav.

In several cases, systems that have been developed have been very time consuming and cost a lot of money, but they still do not fulfil the users requirements and requests. To make new systems better, you have to find a way to communicate that allows the developers to understand the needs of the user. The aim for our thesis is to highlight the importance of communication in system development. To investigate this we have choosen to do a study of the real-estate system. The work methods that have been used include mock-ups and informal conversations with the user, who is employed by the Church of Sweden in Ronneby.

This thesis has aimed to study steering process and institutionalization in the context of educational policy work. This has been conducted by using empirical material from the political decision-making process that preceded the implementation of a new national program on how principals should be educated and certified. By using an aggregated theoretical point of view containing new institutionalism and traditional Swedish curriculum theory, the process was analyzed from different perspectives. The results depict a process that contained several actors who tried to shape the principal education program differently. From the theoretical perspectives, the decision-making process could be understood as an act of both self-interest as well as trust in their own beliefs and cultural values.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security. In order to study usability, a test group of ten persons have been used to evaluate the usability of the system.

Syftet med detta kandidatarbete var att sätta samman ett promopaket bestående av en webbsida och en demo-EP med passande grafisk design. EP:n har tre spår elektroakustisk instrumentalmusik av skiftande karaktär, samt ett stilrent men ändå suggestivt omslag. Webbsidan är till för att presentera mig själv och mitt arbete (inte bara musik), och är byggd med hjälp av HTML, PHP, CSS och MySQL..

Our bachelor thesis is a visualisation made in 3D-graphics of how the horserace track in Tingsryd perhaps will look like in the future, complete with a miletrack, steeplechase, and other horserace courses. Today, the race track is only in it?s building phase. The inner field-group in Tingsryd needed presentation material to show their eventual sponsors, so they contacted us at Media Technology, and we instantly decided to give their idea a try..

The goal of this thesis is to investigate the W3C Geolocation API from a developer?s perspective, focused on whether it makes development of location-based applications more accessible to developers. This has been investigated by looking at available ways to locate, possible uses, the functionality offered, the necessary level of prior knowledge needed for a developer and requirements on developer tools. This has been achieved through studies in relevant areas, a thorough introduction to W3C Geolocation API functionality, and by using the API to develop two different location-based applications as a demonstration. Testing of applications, on different platforms and in different environments, in conjunction with investigation of the rest of the material has shown that W3C Geolocation API in many ways actually makes development of location-based applications more accessible for developers. The API also provides fully adequate functionality and quality to meet the requirements for development of both simple and very advanced location-based applications. Målet med denna uppsats är att undersöka W3C Geolocation API ur ett utvecklarperspektiv, fokuserat på om den gör utveckling av positionsbaserade applikationer mer tillgänglig för utvecklare.

Today, we can see that social navigation is embedded in different kinds of websites, but there is still little support for social navigation in the web browser. Our main concern has been how we construct a tool that fills this hole in the web browser. By letting the theory, the prototype and the focus group serve as input/output to each other we could create a better overview of how the different pieces were intertwined. This has been a crucial mental model for us to obtain since it has helped us to understand how we could realize the theory through our prototype and thereby come to the conclusion of what aspects of the theory that we should put forward to further development. After constructing the prototype we thought that it would support social navigation, but realized after analyzing the discussion of the focus group that we are not there yet.

This thesis work is the result of the company Prisjakt?s wish to develop and improve its current system of opinions for online stores. The challenge was to develop a similar system that competitors are using but better. The collection of information is based on purchases and are collected from Web-shops. The purchases can then be monitored in a control panel.

In the recent years auditing scandals all around the world, deficient internal control has attracted a lot of attention. This has contributed to further requirements on insight and internal control. Those scandals have seriously damaged the auditor?s profession and contributed to a reduced trust among the public. Therefore an extensive work to recover and stringed the trust was started all around the world.
