I programmeringsvärlden har en ren, enkel och testbar kod en stor betydelse. Detta examensarbete avslöjar ett nytt koncept vilket kanske är den viktigaste upptäckten inom metodområdet på senare tid, så kallade Testdriven utveckling (TDD). Testdriven utveckling är ett sätt att utveckla mjukvara och det som utmärker den är att man först skriver ett test som inte ska fungera (röd fas), sedan skriver man en kod, så enkelt som möjligt, som gör att testet ska fungera (grön fas) och till slut ska man våga göra förändringar även om koden fungerar, om man är inte riktigt nöjd eller om man helt enkelt vill optimera sin kod (omstrukturera fas). Syftet med studien var att utvärdera vilka fördelarna och eventuella nackdelarna är med den här typen av mjukvaruutveckling, att motivera varför det är lämpligt att välja den och att visa hur man gör med hjälp av Java, JUnit och Eclipse. Material som användes i studien insamlades genom litteratursökningen och intervjuer.

IKEA HaparandaTornio employ some two-hundred people in its furniture retail store.Keeping track of staff statistics and employee information has previously been achievedthrough the use of a basic Microsoft Office Excel spreadsheet.

The following report documents the development process of that upgrade ascarried out by the author. The project draws on research in usability design and cognitivepsychology to develop a user-friendly interface.

This report contains a programming improvement work in a LabVIEW? fire testing furnace control system for SP Fire Technology in Borås. Here materials and products behaviour are tested and evaluated, being exposed to fire. For this task, UGNET is being used for control and surveillance of the testing furnace system. System hardware has been updated gradually through the years, while the software has been neglected.

When a videogame is being played it is rarely a static experience. A videogame can consist of various systems that affect each other in an unpredictable manner which makes the player experience unique for every player.Throughout the years developers of games have used random chance in a games programming to affect the user experience. Sometimes it even goes so far as to having entire games based around the idea of the game itself randomly generating content for a player to experience.This paper will examine randomly generated content in videogames. It will take examples from existing ones and describe how they use it, and reason regarding the benefits and drawbacks of having random chance affect the user experience.The paper will step-by-step examine the purpose of various commonly occurring objects and features of a typical dungeon in an adventure videogame. It will reason around their purpose, and figure out ways to use them in a structured  manner so that we can guarantee that there will be no deadlocks that the player can't overcome.This will range from the environments in rooms, the shape of them, to the objects and creatures that inhabit them, such as locked doors, keys, and bosses.

Internet is the future and VoIP (Voice over Internet Protocol) is growing in use. Companies are starting to realise the benefits with VoIP. Skype is the number one soft phone on the market but it doesn't satisfy the needs of companies (e.g. transfer calls, redirects calls and so forth) and leaves therefore a gap. The purpose of this master thesis is to provide Objektor AB (thesis initiator) with tips on how to design a usable soft phone that they know is based on relevant human computer interaction research.The method used in the thesis has been iterative development.

The aim of the study was to study the phenomenon of dyslexia on the basis of a literature study. I did a thorough exposition of what dyslexia is and its history and previous research in the area. Further I assumed two questions at issue which were What testimonies are there from the literature of how it is to live with dyslexia? and What learning styles are there for people with dyslexia? I have taken part of testimonies that are to be found about how it is to live with dyslexia according to the people themselves that live with it. In the second question at issue I move on to present a couple of learning styles that are used.

Lean Product Development is a knowledge-based business concept in order to maintain high quality, meetcustomer requirements and to make product development more efficient. An important part of the processis to add a lot of resources at an early stage and execute the development as an iterative process betweendepartments exploring many alternatives thoroughly. The work focuses on how Lean ProductDevelopment is carried out and explores how to manage interaction between different departments andexpertise with regard to cross-functional collaboration and knowledge sharing i.e. learning.The information for the studies was gathered at a major Swedish company from two projects. The projectswere carried out as cross-functional and possible key factors for cross-functional collaboration wasidentified.The results have been correlated with theories of Lean, Product development, Lean product developmentand Learning.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

Web 2.0 represents the next generation of creating interactive applications on the Web. The purpose of this thesis was to develop a service tailored to Web 2.0 technology, where users can post ads for free. The platform is an advertising system specially designed for animals. Surveys and interviews have been done; the result is that today?s advertising services on the Internet are not interactive and user-friendly.The users have the possibility to adapt different part of the system to their needs, such as choice of themes.
