IT - systemen har blivit en del i samhället. IT -system används inom olika områden och verksamheter i och med detta så har användbarhets faktorer i IT -system blivit sådan som inte går att bortse ifrån. Det finns många användbarhetsfaktorer som alla skiljer sig mer eller mindre åt. Gemensamt för dem alla är att ett system bör innehålla visa kriterier för användbarhet för att godkännas av användaren då de använder sig av ett IT -system.Det finns en vilja att skapa användbara system för att underlätta för användaren. Visa faktorer i användbarhet i ett IT -system är genom tänkta medan andra behöver förbättras för att anpassa till beslutfattande och ta hänsyn arbetsmiljöaspekter.

This study is part of an international project, The Third Wave Project. The project aims to conductstudies with students of different cultures to see what they value as important in mathematics andmathematics learning. Part of the project involves carrying out a survey, the WIFI study. The WiFistudyaims to examine values of mathematics teaching that may affect student learning. The valuesthat are examined in this study are based on the mathematical values which are described by Bishop(1991).

The aim in this project was to spread play in the city and acrossgenerations. My way of approaching this challenge was to explore theborderland between playground equipment and street furniture. Thisopened up many possibilities to afford play in places where playgroundequipment often is excluded.The goal was to create one, or more, furniture with play value. The targetgroup was all vivasious people spending time in the public outdoorspace. Through user studies, a lot of serious playing and a lot of testing,the project resulted in a bench called Rollin´.

In my study I have participated at the Fifth Dimension / Active Worlds site in Villa Gymnastiken in Ronneby, where I have worked both as an assistant to the project leader and as a researcher, but also as a participant together with the children. The children are working in a virtual world called Femtedim, created in a internet-based program named Active Worlds Education Universe. The Femtedim-world are bridging together two physical worlds in Ronneby and Copenhagen. My main focus is on an intervention that occurred in the 12th of March when the research-team in Copenhagen, which runs the project in Denmark, decided to create a new challenge for the children since some of them started to get bored. They added gravitation to the Femtedim-world, which lead to a few different reactions among the children. Most of the children didn´t like it and were very hostile towards the idea that they would not be able to fly around freely in the Femtedim-world.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

This report summarizes a Bachelor Degree Project in Integrated Product Development, carried out during the fall 2007 till spring 2008 by three students at the Product Design Engineering Program at the University of Skövde. The project was performed in cooperation with Lundbergs Möbler AB in Tibro. Lundbergs wants to start selling furniture to the public eldercare. The purpose of this project was to adjust one of their chairs. The project layout was to first make a preliminary investigation where the market, competitors? assortment and the purchasing process are studied.

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Today?s housing system for laying hens has limitations for the hens natural behavior. Despite the current law of prevention of cruelty to animals, this might implicate health problems for the hens. This degree project is aiming to improve the situation for laying hens in cage-systems. The aim with our project is to bring forward a draft of a cage that improves the welfare of laying hens.

Värnamo Elnät owns and operates a ripple control system which is used to control loadsespecially when the grid is heavily loaded and for control of street lighting. This report aims atclarifying technical and economic aspects of the ripple control system?s future. The system wasinstalled from 1975 and onwards and its use was greater in those days when the controllableloads where greater then today, the current controllable load level is about 3 MW. The reporthighlights three different aspects of the ripple control system?s future ? retain the currentsystem, reinvest in a newer system or discontinue the system.In the report the author also discusses relevant connections to Smart Grids and future meteringsystems and tariffs.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

Research is a time-consuming endeavor which requires appropriate tools to manage often vast amounts of information. Militarization 2.0 is a research project aiming to explore Militarization in social media. The aim of this project is to design a user interface for supporting researchers in projects involving large amounts of data in qualitative studies. The project will follow the design process of the first version of the Militarization 2.0 research database interface. The design process involves user studies, interviews and design and testing of paper and digital prototypes.

In 1998 the Swedish Socialist Government initiated a project in order to promote economic growth and to end the discriminating social and ethnic segregation in the greater city regions of Stockholm, Gothenburg and Malmo. One of the goals of the project was and still is to promote political participation in 24 of the poorest areas of the three cities. In a quantitative analysis I evaluate whether or not the project so far has been successful in promoting a specific part of political participation, i.e. electoral participation in communal elections. The results of the 24 poor city areas are compared with a group of 14 likewise poor city areas of major swedish cities.According to my hypothesis, general improvements of the socio-economic status of poor city areas ought to generate positive effects on electoral participation in communal elections.

The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

The main purpose of this Master´s thesis, is to describe and discuss what constitutes the library collaboration between The Swedish Royal Library and the National Library of Guatemala, but also to analyse which effects the support has for public library work in Guatemala. The data consists of interviews and direct-observations during 2 months of fieldwork in Guatemala, Central America. The analysis is based on literature studies combined with the answers from the respondents and other results from the field work. We have found above all three factors to be of importance in the constitution of the collaboration between the National Library in Guatemala and the Swedish Royal Library: the Swedish library discourse, the Swedish aid discourse and the relationship between the people involved with the project. The library discourse in Sweden and in Guatemala emphasizes different aspects of the work.
