Denna rapport presenterar ett alternativt sätt att ljussätta terräng i datorgrafik. Tidigare modeller har vanligtvis byggt på lokal ljussättning, som inte tar hänsyn till kringliggande geometri, och har med en extra process approximerat effekten av ljusinteraktionen. Genom att använda sig av en teknik som kallas precomputed radiance transfer (PRT) kan man förberäkna hur en punkt interagerar med ljus för olika inkommande riktningar och undviker därmed att göra detta under programkörningen. Det är viktigt att denna teknik även fungerar tillsammans med level-of-detail (LOD) terrängrenderingsalgoritmer eftersom rendering av alla trianglar i terrängen för varje skärmuppdatering inte är optimalt för dagens grafikkort. Man vill därför representera den underliggande terrängen med fler trianglar närmare betraktaren och färre längre bort.

AbstractPurpose ? The purpose of this study is to investigate possible reasons for long lead-time in a customer driven production, and how the lead-time can be reduced. To fulfil the purpose the study has been broken down into two questions.1. Whichfactorsaffectthelead-timeinacustomer-drivenproduction?2.

In Sweden, little research has been done on the topic of international exchange programs that various schools offer to their pupils. This study investigates how pupils view these exchange programs, and how in their opinion it affects their learning and their level of motivation. The study also investigates the motives for taking part in or declining an international exchange. To answer these questions a quantitative survey and qualitative interviews with pupils with and without experience respectively was carried out.The study indicates that pupils that have not taken part in an exchange believe that it is a time consuming quest that may affect the student?s results in other courses, which is not a belief shared by the other group.

The importance of daylight for humans has been known for a rather long time. Applying this knowledge in the science of urban planning is not very common, at least not in Stockholm, Sweden. Living in a country far from the equator with great differences between daylight and darkness during the year, daylight gets even more important for our wellbeing. This study aims to highlight the subject of daylight planning and contribute to the discussion about how to include daylight in the process of urban planning. By critically observing a new built district in Stockholm and applying guidelines of how to use daylight planning, this paper shows how important it is to include daylight planning early in the process.

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

The purpose of this thesis is to study how organisations are working with repatriation of employees who have been working abroad, especially regarding how their experiences and competences are being utilised and transferred within the company. A qualitative abductive method is used, since the aim is to obtain an understanding of this phenomenon. The main source of information has been 21 interviews. The interviews were executed in two steps; a preliminary study with nine Swedish organisations was followed by our main study, containing 12 interviews with repatriates, their colleagues, and personnel employed at the International Assignment departments at Scania and Volvo. The conclusion of this thesis is that large Swedish companies, which have Swedish employees working abroad do not seem to be working with repatriation according to suggestions given by the theories, even though their performances are better than earlier research implies.

The purpose of this thesis is to get a better understanding of consumers? perception and knowledge of Fair Trade and Fair Trade products in Sweden. Literature was reviewed before the empirical research was conducted. A quantitative method, in form of a questionnaire survey, has been used. We have entered different areas related to our topic.

Background: Female circumcision or female genital mutilation is a tradition that is carried out mainly in Africa. The intervention refers to that part of- or all of the girl?s external genital organs are removed. Aim: The study's purpose was to highlight the consequences of female circumcision in the encounter with western health care.Method: A systematic literature reviews was performed as a method. Twelve articles were selected for the study and these were sought in Chinal, PubMed and PsycINFO. Analysis and interpretation was done according to qualitative content analysis, inspired by Lundman and Granheim.

This paper will discuss the proposed reintroducing of a final degree in upper secondary school. In a public government inquiry that was released in March 2008 a proposal about reintroducing a final degree in upper secondary school was presented. A final degree has not been a part of the upper secondary school science 1968. Why was the system with a final degree abounded and why do the government want to reintroduce it?Research in pedagogy has through the years presented numbers of theories about assessment.

Can landscape architecture be seen as an economical asset rather than as a cost? Can well designed outdoor environments affect real estate values? This study investigates the economical value of landscape architecture and its influence on real estate prices. Research results on the relation between landscape architecture and real estate values are here compiled together with a survey made among players on the Swedish real estate market of their attitudes towards the problem. This study shows that the players on the Swedish real estate market often are unaware of the economical effects of landscape architecture pointed out in the compiled research. The study also shows that to use this information in actual projects several steps need to be taken: better knowledge of the problem, more and better compilations of research results, effective channels to spread the compiled information, proper employment and implementation of the knowledge. Extended knowledge of the relation between landscape architecture and real estate values will result in new ways of making money on outdoor environments. This would in turn have consequences for how the real estate business treat outdoor environments and how landscape architects work. The study is divided into four main questions: 1: Is there a relation between good landscape architecture and real estate prices? 2: What is the view of the players on the real estate market in this matter? 3: Is there more knowledge, research and practical models at hand? 4: What future steps can be taken to broaden the knowledge and apply it to real situations?.

This paper set out to investigate how teachers of Swedish in Sweden implement the grammar objectives of the curriculum in their teaching, through interviewing six teachers. It has been important to compare their methods to modern research of grammar teaching and teaching in general. They have been asked a series of questions to answer whether or not they use grammar terminology as mediating tools, if they intergrate dialogue among students in grammar teaching and to what extent the teachers? knowledge of and attitude towards grammar influence their teaching methods. The results show that grammar is used as mediating tools primarily when it comes to feedback on pupils? texts, though not to a great extent; dialogue between pupils is rare when it comes to grammar teaching; and the teachers? grammar knowledge and attitude affect the teaching methods, primarily in the sense that seeing value in grammar knowledge increases the teacher?s desire to develop new methods for grammar teaching..

Air tightness in new buildings has been discussed for several decades. But the knowledge in the subject is low. With tougher requirements from the Swedish government about energy consumption for a new building required competences how these shall be met. It's not only the thick mess of insulation that are important, it's also the air tightness. This report is about air leakage in Swedish houses.

Even though Sweden is a small country which has a low rate of inhabitants is it one of the worlds leading nations of exporting products from the forest industries. The Importance of a sustainable use of the Swedish forests has been known for many years. In 1903 the first law of forestry were establish. Today the National Board of Forestry carry out inventories of regeneration result. The result of the latest inventory showed that especially the non-industrial private forest owners did not full fill the regeneration work after a clear cut.

AbstractWhy don't (some) regimes with formal democratic features undergo transition to democracy? Which are the internal dynamics of these regimes that can offer comprehension to this state of affairs? The main purpose of this thesis is to advance the above questions, and, on a lower level of abstraction, examine the case of Egypt. The Egyptian regime is characterized by, for instance, a multiparty-system, steps toward economic liberalization, and some level of persistent state opposition, and has been considered on the way to liberal democracy, but can still hardly be estimated as such.Thus, the thesis takes part in a theoretical framework on democratization, and further analyzes the case of Egypt on grounds of socioeconomic development, political culture, and class configuration. By this contextual approach, the thesis adduces that a low level of modernization, an incomplete democratic political culture, and a bourgeoisie supported by the state are impending significant factors. The thesis additionally remarks on the interconnection of the adopted theories, and discusses a potential need for new theoretical propositionsA secondary aim of the thesis also gives some insights into the concurrence of regime stability and the absence of democracy in, what often could be labelled, authoritarian regimes.

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.
