In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Att skriva enhetstester är en viktig del i nya populära systemutvecklingsmetoder som extreme programming. Med testdriven utveckling skriver man testerna innan den källkod som skall testas. Ett vanligt problem med dessa tester är att de blir beroende av delar i systemet som inte är intressant för själva testen. Mock objekt är en teknik som gör det enkelt att isolera tester från allt som inte är relaterat till det som skall testas.Det finns två sätt att se på mock objekt. Den traditionella synen är att mock objekt skall användas som ett verktyg vid isolering av externa system.

Problemområde: En del av de högskolor och universitet som har hemsidor har inte lagt så stor vikt på användbarhet då deras funktionalitet brister. Det är svårt för deras studenter att på ett så enkelt sätt som möjligt nå den information de behöver. Hypotes: ?Användbarheten på högskolornas- och universitetens hemsidor kan förbättras med hjälp av att krav ställs från studenterna.? Genomförandet: För att undersöka hypotesen har tre undersökningar gjorts. Den första var en granskning av de utvalda högskolornas och universitetens hemsidor av författarna. Undersökning nummer två gjordes med hjälp av enkäter som studenter vid de utvalda högskolorna och universiteten fick svara på.

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

Internal communication is very important for the success of an organization. The county council Landstinget i Värmland is a large organization with many managers on different positions. Every one of these managers gets an email every week, with the message that a new manager letter, called Chef, is published on the intranet. With my paper I am examining what the managers think of this letter, how they use it and if managers on different positions differ from each other in opinions about and use of the letter. I want to find out if there is a need of Chef as a part of the internal communication of Landstinget i Värmland.To answer these questions, I have chosen a quantitative method in the form of a questionnaire which is send to all the receivers of the manager letter.

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

This report describes how we, with support from SYSteam Datakonsult AB Värnamobuilds a dynamic website for a fictional company. The purpose of this work is to tietogether our studies with the businesses in the region, and expand our knowledge.Together with Peter Bäckrud from SYSteam we worked out the goals to achieve thispurpose. The goals are to create a polished intranet to a company with the webpagepublishing tool EPIserverThis report begins with describing the goals and visions that were set up. Then follows athorough theoretical background that describes the areas we have touched, to give thereader an idea about the work. The report then moves into the creation phase that talksabout the problem that occurred during development.The creation phase is split up into two parts where the first part gives a good descriptionabout how we designed a usability friendly website that would fulfill the goals we had setup.

This study investigates the use of the social network Facebook among 67 Swedish libraries; 27 academic libraries and 40 public libraries. Data is collected through an analysis of the libraries? Facebook pages and through an email survey. To analyze the data, a series of statistical analyses were performed.The results indicate that the public libraries more actively posted Facebook updates than the academic libraries and that the libraries that had a policy for use of Facebook/social media more actively posted updates than those libraries that did not have such policy. The libraries use Facebook mainly to post links and photos and to announce events, provide book recommendations, and to emphasize special occasions.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

The aim of this study is to analyze how individuals experience their eating disorder, the focus being if anorexia may be perceived as a secure safe zone in the new modern world. The aim is to examine if individuals affected with anorexia nervosa understand the disorder as a solution to the modern worlds changes and the new individual freedom that it entails. This will be analyzed with the help of terms in Erich Fromms theories about escape mechanisms and Catarina Kinnvalls theories about the modern worlds ontological insecurity.The study is based on data collected from four informants of different ages and gender. The interviews were conducted through email and informants were chosen based on a strategic selection and snowball sampling. For the analysis of the empirical material Fromms escape mechanisms (authoritarianism, destructiveness and automaton conformity) and Kinnvalls theories of identity in the modern world have been used.The results of the analysis show that the eating disorder has a great significance for the individual construction and maintenance of identity and that the eating disorder becomes a safe zone to retreat to in a world of performance anxiety.

Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.

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 store?s human resourcesdepartment requested an upgrade to this system with the hope of speeding up andsimplifying the administrative process, as well as to make it easier to monitor HR-relatedtarget statistics. 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.
