Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Denna B-uppsats tar upp prestanda och ÄterstÀllning mellan tvÄ vanligt förekommande mjukvarubaserade RAID-system. Mjukvarubaserad RAID har blivit mer och mer intressant eftersom det Àr ett billigt och bra sÀtt att skydda sig mot hÄrdvarufel pÄ hÄrddiskar. Tidigare har det inneburit prestandaförluster om man inte har anvÀnt en hÄrdvarubaserad RAID kontroller men med dagens snabba processorer Àr det inte lÀngre sÄ. HÄrddiskar gÄr för eller senare sönder och för ett RAID-system som ska vara igÄng tjugofyra timmar om dygnet Àr det viktigt att det Àven dÄ fungerar med bra prestanda. Denna undersökning visar hur mycket sÀmre prestandan blir under sÄdana omstÀndigheter samt hur lÄng ÄterstÀllningstid man kan förvÀnta sig pÄ ett datorssystem uppbyggt av delar för hemmabruk.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

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.

Marknaden för mobila system har utvecklats enormt snabbt de senaste Ären. Idag Àr det ett omrÄde med en allt större omsÀttning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer stÄr stÀndigt inför en utmaning nÀr det gÀller att vÀlja vilket mobilt system man ska satsa pÄ nÀr man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rÀtt mÄlgrupp av konsumenter och dÀrmed kan generera tillrÀckligt med omsÀttning för att driva lönsam utveckling av applikationer. Det rÀcker inte att enbart kolla pÄ vilket system som har mest anvÀndare eller vilket system som genererar mest omsÀttning, utan man bör noggrant övervÀga de förhÄllande som gÀller för just den applikation som ska utvecklas. Genom att följa denna guiden och övervÀga de olika faktorer som vi har sammanstÀllt sÄ kan man som utvecklare göra ett val som Àr baserat pÄ aktuella marknadsundersökningar.

The Dairy business is changing a lot because of some scandals in the agricultural area for example the BSE crises in Great Britain. Because of the scandals the food industry and the farm association have created a certifying system; IP-Sigill Swedish standard system. We contacted SkÄnemejerier as they have been successful in the certifying area. They asked us if we wanted to do a study in the certifying area of dairy farmers. At SkÄnemejerier they gave us most of the literature in the area about certifying. The result of the study, is that we have taken up the most common remark?s. The most frequent remark is journal over routines in management of dairy cows on daily basis. Another remark of the study is that the frequency of the remarks decreases with greater production..

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

This essay examines the Alberte triology, by the Norwegian writer Cora Sandel, from a gender/feminist perspective. Taking Yvonne Hirdman's theory about the gender system as a starting point I will show how the living conditions and the different roles of men and women are represented in the novel and how they are changing during the centuries before and after the First World War.I am particularly interested in Alberte, the main character, what attitude she takes to her position in the gender system and in what way she differs from the traditional female model. Is she a New Woman, a different ?species?, who doesn't fit into the rigid gender system? Does the New Woman have a male counterpart, and is he to be found in the novel? Does the novel give a positive vision of a future where men and women can meet as equals?.

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.

Forskningsrön tyder pÄ att organisatoriska och sociala faktorer Àr den största anledningen till att 90 % av implementeringarna av ERP-system misslyckas. FöresprÄkarna för involvering av anvÀndarna för lyckad implementering Àr mÄnga. I denna studie har vi belyst en fallstudie i en relativt liten livsmedelsorganisation dÀr det har studerats vikten av kommunikation och kommunikationsrutiner för att ta till sig ett nytt system samt hur detta har pÄverkat organisationens anstÀlldas acceptans gentemot det ERP-system de implementerat. Denna studie visar att om kommunikation innefattar kunskapsförvaltning och kunskapsspridning kring det ERP-system som implementeras kan det innebÀra större acceptans hos anvÀndarna, dÄ de fÄr förstÄelse för varför saker och ting sker samt varför deras arbetsuppgifter ser ut som de gör, en kontext kring sina aktiviteter. Vi fann att kommunikationssÀttet, det vill sÀga huruvida den var formell och rutinartad eller informell, inte pÄverkar utfallet av anvÀndarnas acceptans gentemot ERP-systemet, sÄ lÀnge kontexten för aktiviteten förmedlas.

OrganisationsförÀndring behövs för att bevara hög effektivitet i organisationer nÀr omvÀrldenförÀndras. För större organisationer behövs en tydlig avgrÀnsning arbetas fram innanorganisationsförÀndringsarbetet startar. Landstinget i VÀrmland behöver utföraorganisationsförÀndringar pÄ grund av ett förÄldrat IT-system som anvÀnds i verksamheten. EnmÄlgruppsanalys har genomförts av IT-systemet vilket resulterade i tre mÄlgrupper. Intervjuer medpersoner ur de tre mÄlgrupperna har genomförts vilket resulterade i data som anvÀndes till attanalysera och svara pÄ rapportens tvÄ forskningsfrÄgor.

This master thesis is an attempt to study the interface in itself, where the human meets the machine and the problems that can arise. I study a particular interface, namely the OPAC of Libra III. In 1999 IFLA presented recommendations for what an OPAC shall contain, and in one part of my master thesis I compare Libra III with these recommendations from my opinion. In another part of my master thesis I make an investigation where I let five by me chosen persons answer some questions from me, both by doing and verbally. I draw the conclusion that Libra III follows most of the recommendations of IFLA in a sufficient way.

The purpose of this thesis was to ease the implement of an upcoming intranet for a target group who had used the previous system to an unwanted low extent. After qualitative and quantitative studies I found that the users of the current intranet thought it was hard to navigate and did not understand neither the relevance of it in their own work nor knew which information it contained.Since I did not have access to the new system by the time of the making of this thesis I concentrated on rectifying possible problems with the new system regarding the relevance and the contained information. With basis in a number of theories I produced an information brochure, whose object was to inform about the content and to convince the target group of the relevance and utility of the new intranet. .
