This master thesis was carried out at Scania in Södertälje, Sweden. It investigates the possibility of changing a connector interface that is used when there is a need for splicing the wheel speed sensor and thereby determine the consequences.The problems that exist with the current connector interface occur during assembly, as more time is required to complete a connection in a reliable manner. A complete connection requires joining the male and female connector, insert the connection into a protective retainer and then strap a cable tie on each end of the retainer. This process makes it more time consuming and it requires 20-30 seconds to complete the connection. Solving this problem would save time and enable easier assembly, therefore resulting in economical benefits.This thesis was accomplished through discussions with different sections at Scania, studying available documentations, observations during assembly, writing a requirement specification and contacting suppliers.The aforementioned methods resulted in four connector suggestions, the DT and DTMH connector from Deutsch, MCON connector from TE connectivity and MLK connector from Kostal, each of them compliant with the set demands of the surrounding environment.

The aim of this master thesis is to study if the websites of the Swedish public libraries are accessible to all people. According to the library law all people must have access to the public libraries and their information services. Today, when the Internet is one of the largest sources of information, it is important that all people, including those with different kind of disabilities, children, elderly, immigrants and people with old technical equipment, have access to the public libraries websites.We have in this study considered the graphic user interface, the language, the structure and the navigation possibilities at ten public library websites. We have from a checklist of our own, based upon the opinion of different experts such as Jacob Nielsen and Tommy Sundström, investigated the websites.The main finding of our study is that the websites are generally accessible even thou we found a lack of accessible for immigrants. Most of the websites had some pages in English, but none hade all pages in this language.

The scope of this investigation is to decide how and to what extent the energy consumption of apassive house is affected by the users? knowledge and habits. To achieve this a literary study hasbeen made and as a complement the planning of a passive house was completed.The result of a primary study of the rules and regulations that effect passive houses in Swedenshows that the user?s influence on passive houses is a completely unregulated area. Even thoughthere is no regulation, a need for some general knowledge of the passive house concept has beenexpressed.To further investigate how the users? knowledge and habits affect the energy consumption and ifthere is a difference between different households? energy consumption , three main factors havebeen identified.

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user. A new function to keep track of vehicles outside the main working area at the same time as you still can keep track of the other vehicles in the field..

Inom 3D-grafik, visualiseringar, spel och VR finns ett behov av måttriktig modellering. Traditionellt så används CAD-program för att uppnå ett exakt eller precist resultat. Men då CAD-program inte utmatar polygonal geometri så fungerar det inte att använda resultatet direkt i tidigare nämnda kategorier. Denna studie ämnar att underlätta måttriktig polygonal modellering i Autodesk Maya genom ett tillägg i form av ett grafiskt användargränssnitt. Effektiviteten av detta mäts genom tidtagning på modellering av CAD-ritningar i polygoner hos en testgrupp både med och utan tillägget samt en kvalitetskontroll där resultatet jämförs med specifikationen.

Användandet av mobiltelefoner har blivit en del av vår vardag i dagens samhälle. Mobiltelefonindustrin är en miljard industri med stora företag som Motorola, Nokia och Sony Eriksson. De senaste åren har det även kommit in nya aktörer på marknaden som Apple med sin iPhone och Google med sitt mobiltelefons?operativsystem Android. Dessa aktörer har kommit ut med flera nya mobiltelefonmodeller som använder sig ut av pekskärmar.

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 is a heuristic evaluation of Umeå university library?s Online Public Access Catalog (OPAC). It makes use of four of Nielsen?s ten heuristics, flexibility and efficiency to use, match between the system and real world, visibility of system status, and aesthetic and minimalist design. The evaluation was done by having 3 evaluators inspect the interface individually, as per Nielsen?s (1990) recommendation of 3-5 evaluators.

Det blir allt vanligare att utveckla mobilapplikationer för flera plattformar parallellt, samtidigt ärden information som finns tillgänglig för metoder av detta slag knapphändig.Rapporten beskriver utvecklingen av en mobilapplikation till flera plattformar. Det verktyg som använts är ramverket PhoneGap, med hjälp av PhoneGap kompileras en webbapplikation till en mobilapplikation. Det innebär att en webbapplikation utvecklas med hjälp av verktyg somHTML5, CSS3 och JavaScript. För att få en ?mobilkänsla? har ramverk som jQuery Mobile använts.

ABSTRACT System development has become more and more concentrated on development for the Web and this has resulted in larger target groups. It will most surely continue to be so considering that the Web will be the infrastructure of business and services in the future. A big target group involves that the owner of a system can earn a lot of money from the paying users, but that assumes that the system can meet user needs. If a system on the Web does not satisfy the user?s demands then they will use the competitor?s system instead because it is only a mouse-click away.

The work was carried out on Termisk Systemteknisk?s office in Linköping. The aim was to create a computer system with infrared camera technology for quality control and temperature monitoring of manufacturing processes in industry. The system should be configurable such that it can be used on several different issues, including those where the real-time analysis of camera images is required.The developed system is based on an existing framework, Panola, to deal with measurement results and images in a database. The framework is built for the system continually check for new data , and the task was to create a foundation upon which to build systems that use the framework, but fully or partially utilize direct calls .
