AbstractEmilia Rönnberg.Barriers to physical activity in adolescents in their late teens. Vetenskaplig C- uppsats HT 12 Physical activity has been essential to human health and well-being since several thousand years. In Sweden, it has been shown that both adults and young people are less physically active than the rest of Europe- a large proportion of young people today do not meet the recommendations for physical activity (60 minutes per day). The purpose of this study was to determine what proportion of young people, i.e. high school students, did not meet the recommendations for physical activity.

The terror attack in New York year 2001 was a turning point in international politics. New policies were reformed in both USA and EU to secure their citizens from terrorism. The power of the institutions has developed and the question is; how does the new security policy affect people?s freedom? Is it the agencies new policies that are restricting the freedom or the actions of a terrorist? The purpose of this study is to examine if the security policies in USA and EU are protecting their citizen?s freedom. Many individuals are not aware of how much the security policies are affecting their lives.

Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.

The purpose of this study has been to investigate how psychosocial support for families where a parent suffers from a life threatening illness can be constructed. The intent was also to explore how the child's perspective is protected and what barriers and opportunities there are for family oriented support. The study has a qualitative approach and includes interviews with four social workers. The interviews were analyzed with a systems theory and attachment theory. The conclusions are that the whole family suffers psychological and social pressures when a parent is sick.

This thesis explore women?s needs when reentering society after having served a sentence at the female prison Färingsö, outside Stockholm and whether those needs are being met in the reentry strategies that are being provided. Parallel to this the thesis also examines if there, based on nonconformity and gender theories, is a socially constructed representation of women maintained in the rehabilitation work.The method of this thesis applied semi-structured interviews and used snowball sampling to expand the network of informants to obtain the data necessary. Totally five interviews were carried out. Previous research has shown that women in prison have much more complex problems than men and that there is a need for reentry strategies that take gender in account.The results showed that in terms of being able to reenter back in society, women needed help to structure a previously chaotic life.

Safe operation of a large synchronous power system as Nordel is not an easy task.There are several aspects to take into consideration. This thesis focuses on the problems due to voltage collapses in a transmission system.The ability to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict the transfer limitation, and a quarter later a renewed estimate is produced and so on. This means that the operator can se his transfer limits vary every fifteen minutes.Our task in this project is to validate the accuracy of the limitations obtained by SPICA.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

The use of computer and video games has increased immensely over the past few decades and today a majority of the Swedish population enjoys them on a daily basis. With such a large number of frequent users, the media reporting on the subject of games becomes interesting and important. How are games represented in the media, and has there been any change in the way they are portrayed as their popularity has grown? ­The aim of this study is to determine if and how the portrayal of computer and video games in Swedish newspapers has changed during the period 1995?2012. The study was conducted with the use of quantitative content analysis and the empirical data was collected from the two most widespread newspapers in Sweden ? DN and Aftonbladet.

This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

A considerable number young of students are suffering from sociopsychological complaints. The psychological complaints emerge from differnt sources. Important factors for psychological well being are experiences of a satisfactory social network, efficient coping strategies and a supportive school climate.The aim of this study was to examine how young girls in the age of 16-18 years old experience and cope with demands from school. To fulfill the aim of this study we have five questions: What do the girls apprehend as a satisfactory/unsatisfactory working environment? How do the girls define stress? How do the girls cope with stress? What importance has leisure time? What importance has the social network? The method we used for this study was qualitative and the material was collected through four focus groups.

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.

By today?s date there are a lot of companies that are in great need of restructuring their paperwork in a more organized way. This can be excellent arranged with the help of properly constructed computer software. The aviation industry is no exception, but actually a good example of this. Täby Air Maintenance (TAM) is a company which is situated in Örebro.

The purpose of this Master thesis is to examine whether the term elasticity is relevant and functional to apply to public library organisations. Another aim of the thesis is to relate the term elasticity to public library organisations in a network society. Sociologist Manuel Castells provide the theoretical framework on the network society. Three investigations (meant to complement each other) in two Swedish public libraries seek to give answers to these questions.To be able to examine which areas of public library activity are elastic, I make a rough definition of what public library organisations consist of ? nine activity fields are identified using IFLA?s guidelines in combination with Swedish law of public libraries.
