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..

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.

We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

Protean career är en av de nya karriärerna och en ny syn på karriär. Den bygger på att individen själv i hög grad styr över sin karriär och dennes utveckling och baserar denna främst utifrån sina värderingar. För att undersöka förekomsten av Protean career orientation och dennes eventuella samband med kompetensutveckling genomfördes en enkätundersökning på en arbetsplats som resulterade i 134 deltagare. Korrelations- och regressionsberäkningar utfördes på insamlad data. Resultaten visade att det fanns ett samband mellan Protean career orientation och kompetensutveckling och att det förstnämnda var en stark prediktor för kompetensutveckling.

ABSTRACT New in a foreign country ? the importance of civic orientationJessica Gerhardt & Hiba Sultan We have examined the information on parenting in Sweden that is given to new immigrants through civic orientation. The aim of the study was to investigate how new arrivals are being informed of Swedish laws and regulations relating to child rearing and corporal punishment. The study also aims to examine how a lack of information about raising children in civic orientation can affect newly arrived families. Our empirical work has been created by a focus group interview with the child and family unit on social services and a call interview with an SFI-teachers who teach newly arrived immigrants in civic orientation.

The purpose was to examine relations between motivation and goal orientation, perceived ability and perceived motivational climate among persons working out in gym. Another purpose was to study differences in motivation, perceived ability and motivational climate among men and women. The final purpose was to study interactional effects on the dependent variable motivation. The participants were 59 men and 69 women. The instruments used were Task and Ego Goal Orientation in Sport Questionnaire (TEOSQ), Harter´s Competence scale and part of Mahoneys R-5 test.

Varje år genomförs ungefär 3,5 miljoner personlighetsprofileringar med Myers-Briggs Type Indicator®, MBTI ®. Det gör instrumentet till ett av de mest använda psykologiska testen i världen och det innebär att lika många människor får en etikett på sin personlighetstyp som kan användas på olika sätt. Det finns studier, till exempel av Carlyn, som talar för att MBTI är ett pålitligt instrument, men det finns också studier, till exempel av Pittenger, som hävdar motsatsen. James Michael menar att enbart MBTI ger en alltför inkomplett bild av en ledares beteende. Kanske är det klokt att komplettera MBTI med andra testinstrument för att få en komplettare bild av en individ. En modell som skulle kunna komplettera MBTI är motivationsteorin Self-Determination Theory, SDT, och tillhörande delteori General Causality Orientation, GCO.

The aim of this essay is to investigate the implementation of The Social Orientation inSweden. The Social Orientation is a part of the new, one year old, establishment law and isaimed at all newly arrived refugees and immigrants. The aim of the law is to help establish allnew arrivals into the Swedish society by providing knowledge about life in Sweden. Theeducational program is at least sixty hours long and covers: the public authorities in Sweden,laws and regulations, work and education, healthcare, children and family issues in a person?smother tongue.In order to achieve my aim I have chosen two questions: How has the law been implementedin Swedens three counties: Stockholm, Sörmland and Uppsala? What conditions are there fora successful implementation?In order to answer these questions I have used the traditional, ?street-level bureaucrats? andnetwork perspectives and issues for my study of implementation.

The purpose of this study was to identify exerciser athlete?s motivational orientation, coping strategies used and stressors that primarily is perceived in gym training. The study also studied gender differences in relation to motivation orientation, coping strategies and stressors. A survey was conducted with a quantitative design. The study included 118 participants (43 women and 75 men) aged 18 - 42.

Groups that are often referred to as being dismissed in society in general is by some aspects also considered being so in political arenas. A recent compilation of existing research over structurally based objections of gaining power and positions within Swedish parliamentary politics highlight a lack of research considering whether sexual orientation could be such a discriminatory basis. Using a queer theoretical approach, and drawing on concepts such as heteronormativity and homophobia, the principal aim of this essay is to illuminate aspects of local parliamentary political areas where discrimination on the grounds of sexual orientation become relevant. In order to do so six in-depth interviews with homosexual politicians have been conducted. Finding a queer potential in certain ideological parliamentary political environments that enable homosexual politicians to be open about their sexual orientation, it still relies upon the individual to be confident enough not to interpret the political context as homophobic and heteronormative..

The Swedish TV broadcasting market is constantly changing together with the players in it. The questionto be answered by this paper is how the players in the market handle these changes and to what extentthe players are changing the market. Also, are there any differences between the public service andcommercial players in this aspect? The purpose of this paper is to create a better understanding of theSwedish broadcasting market and its player's market orientation. Through case studies of the three mainbroadcasting companies, SVT, TV4-gruppen and MTG, the market is analyzed from their perspective.The conclusions from the analysis show that there are differences in the market orientation betweenpublic service and commercial players, where the commercial companies are more market driven..

När Sydafrika blev en demokrati 1994 gjordes utbildningssystemet om. En del i de storaförändringarna var att introducera Life Orientation, ett nytt ämne från och med 1998.Forskning har visat att införandet av ämnet inte varit friktionsfritt, vilket bland annat berott påatt ämnet varit nytt och det varit brist på lärare med relevant utbildning för att undervisa i LifeOrientation.Syftet med den studie som gjorts var att ta reda på hur lärare på en High School (årskurs 8-12)upplever idrottsämnets ställning är på deras skola, mot bakgrunden att ämnet integrerats i LifeOrientation som ett av sex delområden. En kvalitativ forskning har genomförts medsemistrukturerade interjuver som metod. Resultatet i undersökningen visade utifrån de trefrågeställningsparametrarna; uppfattningar om ämnet, upplevelser av ämnet och åsikter om demateriella förutsättningarna, att lärarna upplevde att ämnets ställning var låg på deras skola.Nyckelord: Sydafrika, utbildning, Life Orientation, idrott och hälsa, ställning, status,upplevelser, materiella förutsättningar.

Navigating to different locations isn?t always easy. Imagine then how it is for people with a visual impairment to walk across the street or to get from one point to another. The Swedish Association of the Visually Impaired (SRF) has pointed out that today's society is not sufficiently accessible to people with visual impairment and there are improvements that need to get done. Technology is something that has evolved a lot this last decade and occurs today almost everywhere in our environment.In some areas, technology has facilitated people's daily life very much and we have therefore chosen to examine whether a combination of several technical functions integrated into the fictive artifact called Eyenavster can facilitate outdoor orientation and increase the accessibility for people with a visual impairment.Qualitative data collection methods have been used in this study by six interviews to answer our question.
