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.

Many of today?s societies are built on established financial structures that are controlled by states and central banks. These structures are built on a clear perception of economic systems as established but invisible institutionalised concepts that are operated by millions of organizations worldwide. An idea of counteracting against centralized economies by introducing a currency that no state or bank controlled was developed in the beginning of the 20th century. In 2008 the idea was realised by the introduction of Bitcoin, which is a digital currency and transaction system without any centralized emitter or controlling organ.

Denna uppsats har skrivits som en del av de studier i krigsvetenskap jag erhållit under min tid vid yrkesofficersprogrammet.Syftet med uppsatsen är att beskriva sambandet mellan de grundläggande förmågorna ledning och rörlighet samt begreppet högt stridstempo vid förband av lättare karaktär.Den metod som använts i uppsatsen är en fallstudie som bygger på en kvalitativ textanalys. Genom en granskning av två valda operationer genomförs en analys efter varje skede. Den teknik som använts för insamling är litteratursökning. En frågeställning har behandlats: Hur såg sambandet ut mellan högt stridstempo och de grundläggande förmågorna ledning och rörlighet vid Operation Market Garden samt Operation Merkurius?Utifrån mina gjorda fallstudier visar resultatet på att i manöverkrigföring är begreppet högt stridstempo av stor vikt för att lyckas med striden.

Som operationssjuksköterskor med lång erfarenhet av operationssjukvård har diskussioner kring munskyddets vara eller icke vara funnits, huruvida munskyddet verkligen skyddar patienten mot postoperativ infektion, eller varför munskydd egentligen behövs. I rollen som operationssjuksköterska ingår ett ansvar för patientens säkerhet, däribland ingår att se till att hygienrutiner följs.Om en patient får en postoperativ infektion orsakar det ett extra stort lidande för patienten, vilket även kan innebära att vårdtiden blir längre. Om operationssjuksköterskor kan undvika detta lidande för patienten genom att använda och hantera skyddsutrustningen i form av munskydd på rätt sätt uppnås ett av målen på operationssalen. Problemformuleringen är: på vilka vetenskapliga grunder rekommenderas användandet av munskydd? Syftet med studien är att beskriva på vilka grunder munskydd bör användas på operation.Metoden är litteraturstudie som är en litteraturöversikt.

The aim of this masters thesis is to examine the picture book canonization process in pre-schools. To succeed in this I have examined what pre-school staff believe to be the criteria of a good picture book. Together with an observation of the pre-schools current collection, other factors which can influence the collection of the picture book are included. This constitutes the foundation for a description of the pre-school picture book canon. To pursue this goal, I have used the methodology of focus group interviews with staff from two pre-schools in a middle-sized town.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

The animal welfare act in Sweden states that dairy cows need to have at least a dim light present at night, but there are no recommendations for what intensity the light should have. It is unknown how cows perceive and react to low light intensities and earlier studies on this topic are limited. Red light as night light has also been suggested, based on the cows? inability to perceive red light. This have however been questioned. The aim with this study was to investigate how four different light intensities affect dairy cows behavior.

This essay is derived from a case study about the SIRA school in Betlehem. SIRA is classified as a special education school with financial support from the Swedish International Relief Association. SIRA acts to provide support for children with reading and writing difficulties in their daily school work.The study's aim to describe the context for SIRA's specialized educational activity. The formulated questions should provide answers to which factors that influence SIRA's work, its goals, development, and the distinguished pedagogical approach.During the research comprehensive interviews were conducted with parties which can influence the way schools operate and provide the necessary support for students. Factors that influence the school's operation are analyzed from a ecological development perspective created by Urie Bronfenbrenner. The theory advocates that a student's development and interaction mainly comes from participating in activities, social roles and relations.This constant process of mutual adaptation between the developing individual and its surrounding environment is to be defined as its own entity. The result shows that SIRA's practice a special educational operation with focus on an approach which strengthens the student's identity and communicational skills..

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level. The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.

Patients who undergo surgery receive general anaesthesia or any form of conduction anaesthesia during the operation. For most people it is strange, unexpected and for many something completely new to be a patient and undergo surgery. Awake conduction anaesthetic patients? experiences from the intraoperative period were little studied. The purpose of this study was to examine awake conduction anaesthesia patients? experiences.

The structure of the Swedish public library field has been evolving during the last decades. The traditional mission of educating the citizens to become responsible, democratic and knowledgeable members of society has in a way led to the integration between public and school libraries. Lately new co-operational models have been under debate and a sense of resistance has arisen because of the economical and market influences. In parallel with closure of library branches new libraries have evolved in malls and wash houses and some with self-service with no use of librarians. This work shows how co-operation in rural areas finds the common goals for the people living there who are concerned about keeping the service needed including the public library and thus using existing means and crossing borders of commercial thinking.

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

The purpose of this study is to get the cadastral procedure for condominiums to become more affordable. The aims of the study is to examine how the number of condominiums, the number of joint facilities and the number of joint property units that are formed in a condominium cadastral procedure in Sweden influences the cadastral procedure cost. To get an overall perspective the study also explores how the chosen forms of co-operation have worked out in association management.A condominium is a type of three-dimensional property unit, which may only contain one residence.  This form of property formation has been allowed in Sweden since 1 May 2009.  At the end of 2014 less than 1000 condominiums had been formed despite the legislator?s expectations for 3000-5000 condominiums a year. The property unit can have access to necessary facilities, not available within the property boundaries, by establishing joint facilities or form joint property units.
