Användningen av strömmande video ökar snabbt just nu. Ett populärt konceptär adaptive bitrate streaming som går ut på att en video kodas i flera olikabithastigheter. Dessa videor tas sedan och delas upp i små filer och görstillgänglig via internet. När du vill spela upp en sådan video laddar du först hemen fil som beskriver vart filerna finns och i vilka bithastigheter de är kodade i.Mediaspelaren kan där efter börja ladda hem filerna och spela upp dom. Om defysiska förutsättningarna, som exempelvis nedladdningshastighet eller CPUbelastning,ändras under uppspelningen kan mediaspelaren enkelt byta kvalitépå videon genom att börja ladda filer av en annan bithastighet och slippa attvideon laggar.

The use of group contribution between consolidated firms is a common phenomenon in Sweden where taxation is not based on the return on the consolidated level but on the return on the individual firms. However, the process of handling the group contribution does not work without problems. This thesis analyzes three main issues where group contributions oppose the Swedish Companies Act. ? The Swedish Companies Act enacts the decision regarding group contributions to be made at a shareholder?s meeting.

The aim of this thesis is benchmarking of the program, based on dynamic programming, that earlier was written to imitate the production planning at TSS.This thesis starts with a chapter about the construction of the DP-program, a shorter description of one and each of the program parts and also a list over the in- and output data in each program part. The DP-program consists of six linked MATLAB-files that together produce an optimized production plan for the different planning groups at TSS. The program reads in and reformat the given data and optimize the production of the articles in one group. Finally it compounds all article production plans and give us a production alternative.After running the program with new data the result shows, resembling with previous results, that TSS could be able to make some distinct cost-savings. According to the program, a 50 % decrease of TSS production costs is possible. .

In cooperation with Hälsoteamet Halmstad a pilot study was made to see if whole body vibration exercise has any effect on muscle strength, movement and experience of pain in people with knee osteoarthritis. Today whole body vibration exercise is a revolutionary exercise method that needs more studies to show the positive and negative effects. Osteoarthritis is a degenerative disease where more cartilage is destroyed than replaced. The most common symptoms are pain, stiffness, restricted movement, muscularly atrophy, tenderness and instability. The cartilage needs pressure to rebuild, it is therefore important that the patient exercise.

This research is about six pedagogue´s and their reflections about the size of the children´s group in the preschools. Then I will discuss the pedagogue?s recommendation on the significance of the size of a children´s group learning and development and it´s practical significance for the preschool function. The pedagogue?s statements will be discussed in relation to The Swedish National Agency for Education (TSNAE) guidelines on group size.The theoretical framework of this essay will take an overview of the social cultural perspective, the group size and its significance for both the children´s learning and development, for interaction and communication and TSNAE advice and guidelines.

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

The DISA method is a universal program developed for teenage girls to prevent depression. The program includes cognitive behavioral techniques are suppose to change negative pattern of thinking, give practice of communication, strategies of problem solution and exercises to strengthen the social network. The purpose of this study is to find out how a group of teenage boys were affected by the DISA program and what factors that may have impacted the outcome. Material from three different studies have been used, a quantitative study in terms of data from self-assessment form CES-D, materials from two semi-structured focus group interviews with the boys and material from a questionnaire filled out by the boys on two occasions during the DISA method. The result of the CES-D indicates that the boys had less depressive symptoms after the final group meeting compared to the first group meeting and also a year later. Analysis of the material from focus group interviews and questionnaire have been made from a communication theory and systems theory perspective and indicate a shift to greater cohesion in the group and demonstrates that communication between the boy-group and group leaders had importance for the outcome.

The purpose of this work is to create more knowledge about the teacher's perceptions of group dynamics and its impact on school activities. How do teachers opportunities and obstacles in order to influence group dynamics among students. The questions I have answered is how the teachers see the importance of a functioning group dynamics in school, how teachers work with group dynamics and how teachers describe the opportunities and obstacles for effective group dynamics. The method I am using at work is a qualitative research method that involves obtaining the teachers' own thoughts, feelings and experiences around the right questions. I have interviewed three teachers in primary schools in the county of Stockholm to find out their particular approach.

The aim was to investigate three anti-racist groups of pupils, their thoughts about respectively their work against racism. The aim was divided into the following questions: - What is, according to the groups, racism and what does the situation look like at the schools? - What does the dynamics in the group look like? - What courses of action are the groups using and how can they improve their work? - How can the groups be described according to the terms work group and basic assumption group? To answer these questions I made three group interviews, one with each group. I analysed the results partly according to earlier research and literature, partly according to the group theory of WR Bion, using the terms work group and basic assumption group. My conclusion is that the word racism seems to have been affected by inflation, since the groups include bullying as well as anti-racists.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.

There are many children in Sweden today, approximately between 100 000 and 200 000, who have parents or a parent that abuses alcohol or other drugs. In this research paper we have reviewed some of the literature concerning these children and their situation. The purpose of this research paper was to make an interview study of a group activity for children that have parents or a parent, who abuses alcohol or other drugs.This research paper is based on interviews conducted with two children and four group leaders. We compared the children's opinions about the group activity to the opinion of the group leaders of what the group activity has given the children. We also wanted to compare our interview study with other similar studies that has been made within this subject.

The purpose of this research is to investigate the group constellation that is, what thoughts, feelings and sensations that arise when students and pupils change groups. The study will also affect students and pupils knowledge of why they should work in groups. Their perceived security will also be something that this study is looking for.The main questions of this study are:How does students and pupils experience the phenomenon of "group replacement"?What is considered to work or not work in the new group formations?The method that is used in this study is based on six qualitative interviews with students and pupils from three different levels of education. The target groups are college and high school students.

The purpose of this study was to identify the way in which history textbooks from the 1980s, 1990s and 2000s used for grades 7-9 depicts World War II from a eurocentric perspective. A qualitative textual analysis was used to achieve the purpose. Three history textbooks from each decade was included in the study, also comparisons have been made to see any changes over time. The study used John M. Hobson matrix describing how the Occident and the Orient are defined from a eurocentric perspective.

This report describes how we made a dynamic website combined with staticalweb pages and a web shop for the Swedish company Tyger & Ting.The employer Tyger & Ting wish to run a working web shop on their site butthey want to keep their old system of updating pages with their old applicationfrom Intellyweb1, which creates statical HTML pages.The goal of this exam paper has been to learn to create a functional web shopwith user friendly layout and appealing design and also to take orders andfulfill wishes from a real employer.The report is describing how Intellyweb?s application and its statical web pageshas been implemented on a dynamic web page. The report does also describehow this site has been build and how the problems with the coding have beensolved. The coding has been made with HTML, PHP and MySQL. CSS hasalso been used.

The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signaltransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.
