Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

A Geographic Information System (GIS) is about presentinginformation with the map as a base. This is increasingly being used on internetsites and in mobile apps. With a GPS it is possible to see where you are andhow to reach a destination or check if the bus is in time. A question to ask isif this technology is possible to implement in ordinary primary schooleducation. If it is, learning history, geography, religion and so on with a GISlearning tool might be possible.

The articles used to describe this condition were found in the databases: PubMed and Cinahl. Ten articles were included in the result: five with a qualitative approach, two with a quantitative approach and three with both qualitative and quantitative approaches. The results were presented through three headings: physical, psychological and social.

Background: In Sweden around 6500 women suffer each year from breast cancer and during lifetime every tenth women is affected. Mastectomy (removal of part of or the whole breast) is carried out mostly in purpose to remove malign tumours or in prophylactic purpose. The breast can be rebuilt through breast reconstruction. Method: The result analysis was based on nine articles. A Manifest content analysis was used and data from the articles where divided into themes and patterns, on the basis of these categories were created.

The aim of this study is to examine physical education teachers? and students? views on the thesis and its part in the physical teacher education program at The Swedish School of Sport and Health Sciences.Does the view on the thesis differ between techers/students and the program with its curriculum and other policy documents?What does students/teachers value in a thesis?Does teachers/students have a mutual habitus concerning the thesis in the form of essay writing and how is this expressed?The study is based on a qualitative survey in which the respondents mainly answered open-ended questions with written answers. These answers have been categorized and analyzed with the aims of the study and the previous research in mind. The views on the purpose of the thesis differ, both within the group teachers/students and to a certain degree in relation to policy documents. The value of the thesis differs within the group.

The aim with this thesis is to investigate how librarians experience communication with children in reference interviews. In today?s interactive community it is meaningful to study how children communicate with the librarian in virtual reference interview as well as in ordinary reference interviews in physical libraries. Focus has been on finding out what children ask about and how they are asking in virtual reference interviews and in ordinary reference interviews, what type of information needs the children have. The study also focuses on which barriers there can be in reference interviews.

AimThe purpose of the survey was to see how students relate to feedback in physical education. The aim was also to find out how students like to receive feedback (written, oral or timing). The survey will also specify what kind of feedback the teacher provides.QuestionsHow do students react to feedback?How do students want to receive feedback?What kind of feedback do the students receive during the lessons in physical education?MethodThe method used in this study was qualitative group interviews with an observation before the interviews. The school that participated was my placement school during my teachers program and it is located in a suburb south of Stockholm.

We travel more to day than we have ever done before and there is an abundance of destinations to choose from. All -destinations have vantages and disadvantages and the things that are favourable for one traveller can be the opposite for another. So the questions are, why do we have different opinions about the same destination and what is it that makes us choose one destination before another?The purpose with this thesis is to investigate if the demographic factor age has an influence on the Swedish traveller?s opinion about winter destinations. The thesis also investigates if there is a link between the traveller?s demography and their opinion of a destination.

This thesis examines the tendering process from the point of view of Swedish building contractors. The purpose with the study is to chart the decision process for the contractors during the tendering process. The study is designed as a survey study. This made it possible to reach a wide base of respondents, not letting such factors as geography being an issue. The survey itself was characterised by a very high response rate compared to other similar studies. The result from this study shows that former experience from similar projects, current workload and the clients economic condition are very important factors for both whether or not the contractor will bid for a project as well as the cost estimation and tendering price. Former experience from similar projects is also an important factor for the determination of the indirect costs.

The aim of the present literature review was to describe and evaluate the effects and experiences within the complementary approaches such as aromatherapy, tactile massage and acupuncture amongst palliative care patients. Search through Medline (through Pub Med) database and additional manual search was conducted. In total 16 articles fulfilled the inclusion criteria and were reviewed. The result was presented under respectively category: aromatherapy, tactile massage and acupuncture. Physical and psychological effects as well as experiences from the treatments were also documented under the different complementary approaches.

Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

Bakgrund: Tidigare studier har visat att barn har sämre styrka i överkropp och bål samt är mindre fysiskt aktiva nu än tidigare, detta skulle kunna medför en ökad hälsorisk framförallt på längre sikt.Syfte: Att undersöka om ett pass med 4 min Tabata intervaller med stabiliserade övningar, varje skoldag under en 6 veckors period gav någon skillnad på de fysiska testerna och gav en ökad stabilitet och styrka hos barn i åldern 7-9 år.Design: Studien genomfördes som en interventionsstudie med en kvantitativ ansats.Metod: 42 barn varav 23 flickor och 19 pojkar i åldern 7-9 år deltog i studien som genomfördes på skoltid i klassrummen. Utöver studiegruppen användes 13 barn som kontrollgrupp de genomförde enbart de fysiska testerna före och efter studien.Resultat: En signifikant ökning av antalet push-up (P<0.05) och push-up (knä)(P<0.05) kunde påvisas efter studien.Konklusion: De fysiska tester som visade signifikanta förbättringar hade liknande övningar inkluderade i Tabatastudien..
