Popular Abstract in Swedish Ett centralt problem inom området datorseende är att utifrån bara ett antal bilder av föremål, återskapa formen av föremålet som avbildats. Samtidigt vill man även återskapa hur kameran rört sig mellan de olika bilderna tagits. Detta är det så kallade struktur och rörelse-problemet. I avhandlingen löses detta problem för olika typer av kameror samt olika typer av objektThis thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. Much of the thesis is centred on the problem of finding initial estimates of the structure and the motion using a small set of image data. These initial estimate

Lignin, the second most abundant natural polymer, has emerged as a potential alternative material to petroleum-based chemicals and renewable resource for the production of diverse forms of aromatics, biofuels, and bio-based materials. Thus, it is becoming important to understand its structure and properties to provide key features and insights for better/efficient lignin valorisation. In this work

Mesosiderites are rare, differentiated meteorites, so-called stony-iron meteorites—they are impact breccias composed of an unusual mix of crustal basalt and pyroxenite, core-derived metal, but no mantle materials. This odd mixture makes their origin enigmatic and has inspired many different formation theories over the last several decades. Some of the outstanding questions have regarded the origin

We take a logical approach to threshold models , used to study the diffusion of e.g. new technologies or behaviors in social net-works. In short, threshold models consist of a network graph of agents connected by a social relationship and a threshold to adopt a possibly cascading behavior. Agents adopt new behavior when the proportion of their neighbors who have already adopted it meets the thresh

Mesosideriter är sällsynta sten-järnmeteoriter med ett gåtfullt ursprung. Deras ovanliga blandning av skorp- och kärnmaterial har föranlett många bildningsteorier under det senaste århundradet. Några frågor har avsett ursprunget till metallen, huruvida den kom från en annan himlakropp, eller från moderkroppens egen kärna, samt varför det finns så pass lite mantelmaterial. Nedslag har haft en centrMesosiderites are rare stony-iron meteorites with enigmatic origins. Their unusual mix of crustal and core materials have inspired many formation theories over the last century. Some of the outstanding questions have regarded the origin of the metal, whether it came from another celestial body or from within the parent body, and the absence of mantle material. The role of impacts has been central

This thesis consists of four papers that broadly concerns two dierent topics. The rsttopic is so-called barycentric Markov processes. By a barycentric Markov process wemean a process that consists of a point/particle system evolving in (discrete) time,whose evolution depends in some way on the mean value of the current points in thesystem. In common for the three rst papers which are on this topic

Energy is among the main driving forces needed for sustainable development. Provision of energy services, from the supply side to transmission/distribution and use, must include management, and good management requires tools. Energy planning is a tool for managing the community energy system through assessing and balancing supply and demand. This thesis explains an approach to energy planning whic

Nationalism and the urge for independency has increased since the development of a Kurdish autonomous region in Iraq. The purpose of this study is to further our understanding of the internal national dynamics in the Kurdistan Regional Government (KRG), and describe the political parties’ perspective on independency in relation to tribalism and national identity. The main empirical material has be

Motor inhibition refers to the ability to inhibit immediate responses in favour of adaptive actions that are mediated by executive functions. This ability may be an indication of general cognitive ability in animals and is important for advanced cognitive functions. In this study, our aim was to compare motor inhibition ability of two closely related passerines that share the same habitat. To do t

Background and aim The paper is based on a study of hunting tourism enterprising in Sweden. The paper demonstrates how game meat is ascribed different, sometimes conflicting values in the moral economy of commercial hunting and identifies an emerging process of servitization of the game meat. Recreational hunting in Sweden can be described as embedded in two different but overlapping cultural and

Intrapersonal parental factors play a significant role in the development of problematic gaming in children. However, few studies have explored parental perspectives on their relationship with a child engaged in problematic gaming, as well as the need for support parents perceive in relation to the child’s gaming. We conducted semi-structured interviews with 12 parents (83.3% women) of 11 children
