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 wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.

The aim of this essay is to investigate to which extent the novel Kvinnor och äppelträd by Moa Martinson can be classified as a polyphonic novel. The concept polyphony was established in literary theory by the Russian language theorist and literary critic Michail Bachtin in 1929, in his book Problems of Dostoevsky?s poetics. In order to understand and comprehend the concept of polyphony I have used an interpretation due to the literature scholar Robyn McCallum. She notes that the characters in a polyphonic novel function as focalizers.

Syftet med denna uppsats har varit att undersöka på vilket sätt attacker utförda av al-Qaida kanhänföras till begreppet asymmetri och på vilket sätt man kan tolka den amerikanska administrationensrespons på dessa som uttryck för ett linjärt tänkande. Vidare vill jag undersöka vilka svårigheter somkan uppstå i relationen mellan en linjär omvärldsuppfattning och asymmetriska metoder. För attuppfylla syftet med uppsatsen kommer tre av al-Qaidas attacker att studeras. Dessa är: attacken mot deamerikanska ambassaderna i Afrika, 1998, attacken mot USS Cole, 2000 och attacken 11 september,2001. Rapporterna från den amerikanska administrationen efter respektive attack kommer att utgöragrunden i mitt empiriska material.

Stora Enso Skog has a long term contract regarding felling rights and silvicultural activities on forest owned by Bergvik Skog. In the autumn 2006, Bergvik Skog proposed a new thinning program, ?Bergvikgallring?. The new program implied an increased focus on extraction of smaller trees compared to the present thinning program, Stora Enso Skog?s ?Kvalitetsgallring?.

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).

The purpose of this study is to map out and to analyze the spatial variation of female representation at the national level in established democracies. The aim is also to explain the variation in the female representation. The main questions that the paper tries to answer are:1.How does women representation in established democratic parliaments vary?2.Why does women representation in established democratic parliaments vary?This study is a comparative and statistic study, i.e. a study that includes a bigger number of countries and where quantitative analysis methods are used in order to achieve comparative analyses.

The present essay concerns Walter Benjamin?s thought regarding history and temporality as he articulated it in his last work that was only published posthumously: ?U?ber den Begriff der Geschichte?. The purpose is to analyze Benjamin?s construction of historical materialism and to suggest a reading of it as directed towards an opening of history. For Walter Benjamin, every moment presents itself as a possibility of radical otherness: a possibility for things to be different.

In this paper, generic reference in a collection of juridical texts is examined, with focus on third person singular pronouns. The object of the study is to find out which generic pronouns occur in the material along with their relative distribution, but also to display further use patterns and to offer plausible explanations for these patterns. Another object is to evaluate whether the use of generic pronouns corresponds with language planners? recommendations for non-sexist language. The corpus studied consists of Rikspolisstyrelsens författnings­samling (?Statute Book of the Swedish National Police Board?), comprising 172 documents written between 1974 and 2009.The study is divided into two parts.

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.

This study examines how women are portrayed in four of Disney?s feature films, withthe focus on the presentation of relations between women. The films examined areSnow White and the Seven Dwarfs (1937), Sleeping Beauty (1959), The Little Mermaid(1989) and Frozen (2013). The aim is to analyse the development that has taken placefrom a gender perspective, from the earliest film, Snow White and the Seven Dwarfs(1937), to the latest, Frozen (2013), and to reveal the significance of the femalecharacters for each other. The films? portrayal of women and female relations isdiscussed in relation to previous criticism of Disney for their stereotyped portrayal ofwomen, and through a thematic comparison with the known fairytales on which thefilms are based.

This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

This thesis analyses the intertextual relation between Birgitta Trotzig?s I Kejsarens tid and the works of the Polish author Bruno Schulz, using a hermeneutical method. The application of Manfred Pfister?s model for qualification of intertextual intensity initially motivates that the most important intertextual relations should be sought in the realm of ?refer to? rather than ?use?. According to the hermeneutical approach, the conclusion demands an exposition of Birgitta Trotzig?s interpretative practices in relation to intertexts.
