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..

The aim of this study is to highlight the computer as a learning resource in the education and give us knowledge about how the students uses the computer in year one in a selected High School where one computer per student were introduced in autumn 2011. The aim is also to contribute to the discussion about how the computer can become a natural learning resource for all students in all subjects, including the students in need of special support.How are the High School students using the computer?Are there differences in computer use, whether the student is in academic or vocational program?Are there differences in computer use between boys and girls?Do the student experience that the digital competence is increasing together with if they experience the computer as aid?In what degree do the teachers encourage the students to use the computer?How much do the students use the computer to learn mathematic?The study is based on a survey of all students in year one in a municipal High School.The result of the study is showing that the students first of all use the computer to play music, surf the Internet and to be logged in on social media (eg. Facebook). The students have learned to use the computer for the tasks they need, although the teachers don?t encourage the students to use the computer in any higher means, not in mathematics and not in other subjects.

How does the computer influence teenagers' lives. I interviewed five young people, and gave a questionnaire to another 47, about this.What I found was that they were aware of and handled well the risks with the Internet and the computer, but had problems with the computer taking too much of their time. They wanted more time for their families and outdoor activities. It was mainly the Internet that seemed to have an influence on the teenagers, not the computer as a machine. They told me that there was a rough climate on the Internet, partly because of the possibility of being anonymous.

This Masters thesis concerns computer games in Swedish public libraries. We have investigated the opinions of public librarians concerning what they think about computer games, and to what extent they believe it should be a part of the public library. The method we have chosen is qualitative interviews. The theory we have used is a pedagogical literature strategy, which we have reformulated so that it fits our investigation. The results show that the interviewed public librarians think that the library should offer computer games for children and youths to use at the library, and that they should offer computer games for lending, to all the library users.

The purpose of this dissertation is to create an understanding of how a personal idea in the mind of an entrepreneur becomes an outspoken vision in one biotech company. More specifically, for what purpose the vision is used at different stages, how it is communicated, its content and what impact previous visions have on future vision work and in order to reach a deeper understanding of how vision develops over time and how it is used we have employed a qualitative approach based on a case study. The theoretical framework starts with the concept of vision and related concepts. Furthermore, the entrepreneur?s and manager?s usage of vision is examined.

This thesis is an attempt to study computer games and playful computer programs for childrenand youth at Swedish public libraries. The main method used, is qualitative interviews.The main reason the libraries in the study offer computer games and playful computer programsto their users, is that every member of the society shall have opportunity to use newtechnology such as computers and computer programs. The users of this media are for themost part boys. The librarians in our study wish to have pedagogical games and programswithout violent themes at their libraries. Lending computer games and computer programs isnot of any priority for the libraries..

Leaders have many tools in their toolbox when it comes to managing their firms, assuring that they are moving in the right direction. One of these tools is vision. Vision can be a powerful tool for steering a company. But to be able to use it fully, you must also understand how vision is best conveyed to employees and followers. If you understand the vision as a tool, you can fully utilize it.

This report describes a study, description and testing of parts to an application adapted to the operating system Android. The application is supposed to measure the distance to a car ahead. Apart from distance measurements the ability of the application to calculate its own speed with the help of GPS is tested. From these two parameters, speed, distance and some constants the theoretical stopping distance of the car will be calculated in order to warn the driver if the car is too close to the car ahead in relation to its own speed and stopping distance.Tests were conducted on the different applications that were programmed and the result showed that the camera technique in the mobile phone itself limits the maximum distance of the distance measurement application. The max distance the tests in this thesis revealed was approximately 5 meters.

My choice of topic for this essay is the habits of television and computer gaming among young men; mostly their opinion of male and female objectives. My vision of this, being a woman, I often think of the possibilities men have of choosing games where the female characters, in my opinion, often are exposed in a degrading way. To my help I have earlier works on the topic by media scientist Mary Flanagan as the leading authority. She writes much of the character of Lara Croft, and the way she could be an icon for the computer gaming girls of today, despite she is having a stereotypical body shape. I even want to briefly share my thoughts of the always imminent discussion about media panicking; and whether gaming giving the players positive or negative influences.

Problem: Hur kan en organisation arbeta för att individerna i organisationen ska ta till sig den uttalade visionen på ett sådant sätt att den faktiskt påverkar det dagliga arbetet? Syfte: Vårt syfte är att undersöka vilka faktorer som påverkar spridningen och förankringen av visionen hos medarbetarna i organisationen Metod: Studien baseras på djupintervjuer med respondenter på två fallföretag, Bilen AB och Ljuset AB. Vi har använt oss av en kvalitativ forskningsmetod för att belysa begreppet vision. Resultat: Det går att spåra en vision i en organisation utifrån den metod vi har valt. En vision har ingen kraft i sig själv, utan måste ges liv av företagsledningen.

Tårsubstitut används mycket bland linsbärare och personer med torra ögon. Detär vanligt nuförtiden att arbete i kontorsmiljö och vid datorer ger problem medtorra ögon, Computer vision syndrome (CVS), och att dessa personer dåanvänder tårsubstitut. Ofta står det i tårsubstitutens bipacksedel att de kan geproblem med dimsyn en stund efter applicering.Tidigare studier har visat att aberrationerna i ögat ökar vid applicering avtårsubstitut och möjligtvis är det anledningen till att dimsynen uppkommer.Syfte: Syftet med studien är att ta reda på hur mycket synkvaliteten påverkas avtvå olika tårsubstitut och hur lång tid den påverkas.Metod: Metoden innebar att närvisus och aberrationer mättes på 30 patienter (60ögon) först utan tårsubstitut. Sedan applicerades det första tårsubstitutet(Systane) i höger öga och ytterligare en mätning av närvisus och aberrationerutfördes. Därefter gjordes ytterligare 5 mätningar av aberrationerna, en var fjärdeminut.

This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Klyschor använts flitigt inom olika sammanhang och kan på många vis både förstärka såväl som förlöjliga en känsla. Sett ur ett organisatoriskt perspektiv kan ett överdrivet nyttjande av dessa stjälpa organisationen. Å andra sidan kan en tydlig vision svetsa samman medarbetarna och därigenom skapa en välmående organisation.Denna uppsats skildrar hur en vision blir organisationens vision. Ämnet är omfattande och vi har därför valt att beskriva problematiken utifrån en fallstudie på konsultföretaget HiQ Skåne AB. Uppsatsen baseras på en observation, vilken lade grunden för fem kvalitativa intervjuer.En vision kan spridas på en rad olika vis där kommunikation fungerar som ett verktyg.
