This essay is about the principles and rules that control persuasive computer games. The term persuasive games mean computer games, video games and other similar artifacts that are produced to shape opinion. The rhetorical scholar Ian Bogost at Georgia Tech claims that this kind of games mainly get their persuasive power by using procedural rhetoric and that games as a medium gives special conditions for procedurality.  By procedural rhetoric Bogost means an argumentation that is based on rules and choices, as opposed to texts, movies and images. (Bogost 2007). Bogost describes these procedures as quite specific for games and claims that they differ qualitatively from ?ordinary? rhetorical arguments even if they just as other arguments work by establishing enthymems.

This master thesis is the documented work of the construction process and testing of a three hour laboratory session in mathematics aimed at high school level students. The purpose of the thesis was to create an interesting laboratory session for the science education center ?The House of Science? that could be used as a part of their regular program directed to schools. The thesis explores the possibilities for how one can construct a laboratory session on the topic ?molecular symmetry? as well as the underlying pedagogical theories used to describe learning processes in creative contexts.

This thesis is about how teachers in natural and social science integrate the upper secondary school library in their teaching and how they use it for their teaching. Literature in connection with the study is described. Qualitative interviews have been done with four teachers from each subject and with an upper secondary school librarian.The study has shown that there are differences between the teachers in social and natural science. One group, consisting of mainly teachers in social science, survey the library collection.They give the pupils suggestions of useful material and sometimes they take out material for the pupils, with help from the librarian. The other group, teachers in natural science, uses library tools, cooperates and discusses with the librarian how the pupils should work when they use the library.

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

There is no commonly accepted definition of a business method. It ought to consist of a method or a process of doing business. Business methods constitutes a broad category of patents, it is hard to tell exactly what can be interpreted in to the term. Most of the world's legal systems have made an exception from patentability for business methods. In the USA the exception was abolished in a case 1998.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

This is a thesis on the Intranet use in the European Parliament. We investigated the use from a multilingual point of view, but also from a communication perspective. What we wanted to know was how a multilingual group, with presumably different computer skills, in the organisation handle the Intranet information. What are the positive and negative effects of a multilingual information exchange over an Intranet? To find out, we sent a questionnaire as an e-mail attachment to all members of a chosen committee and their assistants.

Hur kan mobila användare studeras? Frågan blir allt mer aktuell i samband med att vi människor i större utsträckning blir mobila och därmed också använder mobila artefakter som en del av vardagslivet. Denna fråga är framförallt aktuell för de företag som utvecklar denna typ av artefakter. Vi har under detta kandidatarbete samarbetat med ett företag som dagligen ställs inför denna typ av frågor, och vi kommer i denna rapport behandla utvecklingen av en metod för att studera just mobila användare. Att studera användarna är naturligt, då det är de som är nyckeln till vilka tjänster och artefakter som just de har användning för.

Our paper is a study about youth and their self-images. During our practical training period we found that the problems young people had always were connected with their self-image. We therefore wanted to find out what youth believe influence their self-image. The purpose of our study was to examine young people and their self-images in a perspective of the ecological systems model. Essential issues have been what self-images young people have, what they consider influence their self-image most, how they think they can resist influence from the environment and how they would like to be influenced by the environment if they could decide themselves.

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.

This thesis aims to examine how the quality of data that is entered into and retrieved from a corporate group's ERP and Data Warehouse systems can be improved. The corporate group has already taken several measures that will improve the quality of data. For instance the corporate group has updated and merged the previous ERP systems into one. At the same time the corporate group adjusted the settings in the updated ERP system, so that it will be harder to register incorrect data in the ERP system. With regards to the processes and routines, the studied department has efficient written routines and processes.

The Pedagogical progression within MSI ? Based upon The Bologna Process and UPC.In a near future several of the European countries will begin working after new guidelines concerning a declaration called the Bologna process. Everything will be done one step at a time and the declaration will change the way the students are being graded, all this for the sake of making the European labour-market moreopened for all of its millions of students.In Växjö this process is in the making, but to adapt to the future demands the school must also change its ways of teaching.To increase its quality the University has put together a procedure of actions to improve the pedagogical working method in all its institutions. In this essay we would like to elucidate how the work with the Bologna process is proceeding within the institution of Mathematics and System Engineering and whatthey do improve their pedagogical teaching. By doing a qualitative case study on the student at the Computer Science Program we wish to find the answers to our questions..

This thesis presents a general definition of science education and earth science education.An inventory has been conducted of published material during the years 2011-2013, withthe start in 2013 and working backwards for international publications and with no timelimits in time for Swedish publications. Different databases were used during April 2013 forthe inventory.The thesis organizes and analyses published material in earth science education in a tablewith a following discussion.The purpose with the inventory was to investigate the amount and content ofprevious year?s publications in earth science education. Concept inventories were foundto be the most common subject of the found material, followed by virtual field studies. Thelargest amount of publications was published in North America.

The aim of my study is to investigate if and in that case how the writing process and texts written by students in the upper secondary school are affected by the writing tool; does it matter if they write their texts on a computer or by longhand? Another objective is to compare such an effect with the findings of previous studies performed on earlier generations of writers. The first part of my study was a survey. It showed that two thirds of the 67 students participating thought that they would have written better texts in the national writing test if they had been able to use computers. In the second part of the study each of the fourteen participants wrote one text on computer and another by hand.

Improved wireless datacommunication with the forest machines might be the next big step in the logging process. The use for wireless communicationsystems within the forestry is among other things to report the production from the forest machines, to supply the machine opera-tors with the right information and for safety. CDMA2000/ 450 is a third generation mobilecommunicationsystem which could replace the old NMT- 450 and for comparatively low costs. The reason for the low costs is that you only have to use the old NMT- 450 masts and supply them with new equipment. In the test of CDMA2000/450, that has taken place in northern Uppland, two kind of files have been sent.
