This is a thesis written for a master's degree at the Computer Vision Laboratory, University of Linköping. An abstract outer product is defined and used as a bridge to reach 2:nd and 4:th order tensors. Some applications of these in geometric analysis of range data are discussed and illustrated. In idealized setups, simple geometric objects, like spheres or polygons, are successfully detected. Finally, the generalization to n:th order tensors for storing and analysing geometric information is discussed..

Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication.

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

For many people, a good game is synonymous with good graphics. One thing that is often forgotten, is that the graphics only makes up one part of the games. An aspect of the games that is far to often forgotten, is the game?s content and ability to tell stories. Through analyses of the games of the Zelda series, the development of content and storytelling aspects of computer- and video games, since the later half of the 1980:s and up till today, are examined..

In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.

To be able to plan different treatments, accurate data is required. The collection of data is often expensive and that?s why the aim is to lower the inventory costs without loosing the accuracy of the data. Holmen Skog has in its strive to lower the costs, decided to evaluate two different methods for forest delineation, computer aided forest delineation and digital stereo view. This study?s purpose is to evaluate these two methods in regard to usability for a beginner and how good the delineation gets.

Today?s cell phones include more and more functionality, it is no longer uncommon to be able to connect to the Internet or take photos with the cell phone. In this thesis the question is if the cell phone users are interested in this new functionality. Are there people who are interested in a cell phone that in this thesis is called ?Basmobilen? (the entry level phone), which include the following functions; phone call, SMS, phone book, calling lists, clock and the possibility to change the call signal.

Today's technology offers a variety of opportunities to interact with the interactive systems. Human-Computer Interaction in the last decade is the area of research that has contributed the most to this development. But how is this interaction perceived? The user experience is something that is formed by the interaction between human and the computer interactive systems. The objective of this thesis is to investigate how the user experience differs depending on how one interacts with a game.

Warcraft är ett strategidataspel som massor av människor världen över ägnar sig åt. Sebastian Pesic (alias 4K FuRy) är en av världens bästa spelare och dataspelandet har blivit hans jobb. Dokumentärfilmen handlar om Sebastian Pesic och hans verklighet i Warcraftlaget 4Kings. Sebastian kommer att berätta om sina upplevelser och vi kommer att få se honom i action. Filmen kommer att ge en inblick i dataspelsvärlden som många inte ens vet om existerar.

The aim of this essay is to investigate the function and development of non-player characters (NPC) in the TV/computer game Dragon Age: Origins. The NPCs are analysed in order to see if their development is affected by the player character?s (PC) background and interactions. The game?s ethics is also investigated by studying how the NPCs treat the PC and what significance they give to his background and actions.The results show that the NPCs are affected by the PC?s interactions, and furthermore, that they are round characters, which is unusual in TV/computer games.

In this work we?ve been focusing on how to adjust educational computer games in order to make them suited for the educational context of upper secondary school. Our opinion and entrance to the study is that the related developers of the subject, in some ways, have failed to successfully combine and find the balance between the entertaining and pedagogical aspects in the games. Our main questions is which aspects in the games game developers need to take in consideration to satisfy the pupils, but also what qualities that is needed for them to function in their educational context. In order to do that we had to investigate the people of the target groups own perspective on what technological and social aspects in the computer games they assess as important.

This paper has focused on specific aspects of the law concerning the 3rd paragraph of The Care of Young Persons Act (1990:52), LVU. The purpose of this study was to examine the prerequisite other social destructive behaviour in four cases where youths has been under compulsory institutional care because of their computer gaming. The study was composed on a legal dogmatic method and a legal sociologist perspective. The legal dogmatic method implies to examine the law and its elaboration, the legal sociologist perspective focus on the consequences and causes of the court of law. The study shows that problematic computer gaming is an increasing problem in society and that other social destructive behaviour is a wide prerequisite that need new amendment in order to ensure citizens certainty..

The purpose of this study is to investigate in what extension students experience that computer and videogames affect them. I have chosen to focus on the physical, mental and social affect that this activity might bring them. I have also examined how much time the students spends in front of the computer or the videogame and in which social context they play.The method I have chosen to use is a quantitative opinion poll which I used in three classes of the later junior high and I have also conducted five qualitative interviews.The conclusions I have drawn from this investigation are that computer and videogames affects teenagers both physically and mentally. Physically the affects of playing videogames mostly can be derived to the physical inactivity they expose themselves to. The students themselves did not experienced any positive physical affects from their playing.Amongst the mental affects that stood out the most I recognized the social training that online gaming provided and also the intellectual stimulation that certain games offered the player.
