Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

The aim of this thesis is to contribute to the field ofinformation politics, in the areas of the future regulationof The Fundamental Law on Freedom of Expression andThe Freedom of the Press Act. The focus of the study is todiscursively examine how ideas and perspectives ontechnological developments are expressed in a pendingSwedish legislative proposal. The empirical data consistsof an interim government report, SOU 2010:68, writtenby Yttrandefrihetskommittén (Committee on Freedom ofExpression) and analysed using Norman Fairclough'sCritical Discourse Analysis. The analysis is conducted onthree levels: a textual level, a discursive practice level anda social practice level.On the textual level we found that the committeecontinously uses significantly charged expressions todescribe technological development. On the discursivepractice level two discourses were identified.

Children and youth inactivity and sedentary at school is increasing. This means that some of the students have a significant unhealthy lifestyle with physical inactivity, which in turn implies risks of suffering from various diseases, including obesity, type 2 diabetes and cardiovascular disease, all related to a sedentary lifestyle. To prevent illness, it is important that children and young people early get a positive attitude towards physical activity.The purpose of this study was to study the causes of child and adolescent physical inactivity in school, based on teachers 'and parents' perspectives.A qualitative research has been selected. To achieve the study objectives, the author has conducted seven semi-structured interviews, with an appropriate choice of five teachers and two parents with children in school. Data was analyzed with a manifest content analysis.The results show that teachers and parents felt that physical activity is a protective factor for children's health.

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

This thesis is about the idea of public transport and the discussions stirred in the media during changes in ownership. More specifically it is a study of the historical situation of Stockholm, Sweden, where the periods chosen are the 1910s, 1960s and 1990s.During the 1910s Stockholm?s first and largest tram company was taken over by thecity, and a period of public ownership began, which in the 1960s changed form whenthe county council took over the city?s principal authority and formed the politicallyadministered company SL (Storstockholms Lokaltrafik, Greater Stockholm LocalTransit Company). Between these periods the word kollektivtrafik (public transport)was established in the Swedish language. This study describes and compares the ideasconcerning the phenomenon of public transport.The aim of the study is to analyse the ideas, values and ideals concerning public transport in the media, defined as newspapers.

I detta arbete behandlas transient simulering i ett 1D-simuleringsprogram, i dettafall Gamma technologies GT-Power. Vad som behöver ändras i en modell för attden skall kunna simulera en motor under transienta driftsfall med godnoggrannhet har undersökts. När detta är gjort, skall det undersökas hur väl dentransient kalibrerade modellen kan simulera en motor med förändrad rörgeometripå insugs- eller avgassidan, och vad som måste omkalibreras om detta inte ärfallet.Den viktigaste slutsatsen av detta arbete är vikten av att ha en korrekt framtagenkompressormapp i modellen. Den som fanns tillgänglig under arbetet hade baramätdata ned till 70000 rpm. Detta resulterade i en överskattning av massflödet iden lägre regionen i den av GT-Power framställda kompressormappen.

This bachelor thesis project has been executed at Outotec Sweden AB in Skellefteå. Outotecs main business focus is selling mineral and metal processing technologies. A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

Under the hawks wingsDistribution and sorting at the upptagningshem in Sandsbro between the years 1933-1935This paper aims to study a so called ?upptagningshem? in Sandsbro, Sweden during theperiod 1933 to 1935. All the children during those three years were enrolled in theupptagningshem is included in the study, a total of 101 children. The main sources studied areprimary sources obtained from the county archive in Kronoberg which is shown in aquantitative method with the thesis that the upptagningshem works according to YeheskelHasenfelds ?people-processing technologies?, which acts as a sorting device which meanscategorizing and classifying activities where different kinds of people are sorted and based onthe results taken care of, by appropriate other organization that can provide the rightresources.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

From a view of health strategies and techniques this thesis wants to throw a light on how the individual in its"health thinking"is governed.

The study is done whit a theoretical approach of power, with qualitative interviews as method and analysed from a perspective of Governmentality. The object for the study is Socsam and Rehabrådgivarna in Finspång. Socsam is a local project, and their main task is to create cooperation between health- and medical services, social services and social insurance.

Under våren och sommaren 2009 fick jag till uppgift att lära mig mer om HLA och hur man kan använda det för att integrera datorspel och simuleringar. Förr var simuleringar oftast stora specialskrivna program, skapade för att klara av en specifik simulering. Om man behövde förändra på något vis blev man tvungen att skriva om hela simuleringen. Nu med HLA har man fått en standardisering på hur man ska bygga upp simuleringar och vad dessa måste klara av att göra. HLA är alltså en arkitektur för hur man ska koppla ihop flera mindre simuleringar (federater) till en stor simulering (federation).
