This study began with a mission statement from the firm Tobii Technology AB to identify customer needs in the relatively new and rapidly growing market for eye tracking analysis. After consuling external experts, the authors however found that the availability of previous academic published market studies of new and fast growing markets was poor. Therefore a decision was made to execute the task and at the same time create a methadology for future studies in this area. The identification of customer needs, which formed the basis of the insights and analysis, led to frequent discussions between the authors and the firm's supervisors. This resulted in a project plan and a decision that an iterative model would be used, were earlier decisions would be questioned and refined throughout the project.

Denna B-uppsats tar upp prestanda och återställning mellan två vanligt förekommande mjukvarubaserade RAID-system. Mjukvarubaserad RAID har blivit mer och mer intressant eftersom det är ett billigt och bra sätt att skydda sig mot hårdvarufel på hårddiskar. Tidigare har det inneburit prestandaförluster om man inte har använt en hårdvarubaserad RAID kontroller men med dagens snabba processorer är det inte längre så. Hårddiskar går för eller senare sönder och för ett RAID-system som ska vara igång tjugofyra timmar om dygnet är det viktigt att det även då fungerar med bra prestanda. Denna undersökning visar hur mycket sämre prestandan blir under sådana omständigheter samt hur lång återställningstid man kan förvänta sig på ett datorssystem uppbyggt av delar för hemmabruk.

This essay deals with classification of images using the subject classification system Outline. This classification system is used in regional museums and they do often have large collections of pictures. The regional museums have their main focus of culture history. The purpose is to look at Outline from four different aspects: 1. In what way is the system constructed looking at classification theory, 2.

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.

In Sweden the divorce rates has increased during the latter part of the 20th century. For many children it?s everyday life growing up with parents no longer living together. The Parental Code states that "The child's best interests must be central to any decision in custody, residence and access." But what does the child?s best interest really mean and how do we investigate it? We decided to investigate its meaning by interviewing social workers regarding their interpretations of the child's best interests from a family law perspective.

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 åren. Idag är det ett område med en allt större omsättning och det har vuxit fram som en helt ny gren inom Software Engineering. Utvecklare av mobila applikationer står ständigt inför en utmaning när det gäller att välja vilket mobilt system man ska satsa på när man utvecklar applikationer. Valet av system kan vara helt avgörande för om man hittar rätt målgrupp av konsumenter och därmed kan generera tillräckligt med omsättning för att driva lönsam utveckling av applikationer. Det räcker inte att enbart kolla på vilket system som har mest användare eller vilket system som genererar mest omsättning, utan man bör noggrant överväga de förhållande som gäller för just den applikation som ska utvecklas. Genom att följa denna guiden och överväga de olika faktorer som vi har sammanställt så kan man som utvecklare göra ett val som är baserat på 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 Skånemejerier 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 Skånemejerier 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.

The Swedish nonprofit sector is experiencing a sectoral change, moving closer to the corporate sector to become more commercialized. The recruitment of leaders with corporate experience constitutes one of the factors influencing this development. Hence, to create an understanding of this sectoral change, the thesis aims to investigate the motivational forces underlying the leaders' decisions to work within the nonprofit sector. Additionally, the thesis seeks an understanding of why the leaders' decisions were made later in their careers. Through conducting qualitative interviews with leaders representing top management of six humanitarian organizations in Sweden, the study finds that nonprofit leaders with corporate background, analogous to volunteers and employees, are motivated by a sense of relatedness to the vision of the organization.

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?.

As an assurance company has an overconsolidation which must be settled the question that needs to be solved is how to do it. Which are the legal rules that the assurance company has to look after? What is a settling of overconsolidation in a legal meaning? Does an assurancepolicy have to be decided? Why did not the Swedish competition authority (Konkurrensverket) accept the policy from SPP and what can be the consequenses of that decision? Are there any tax rules that needs to be solved?.

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 på att organisatoriska och sociala faktorer är den största anledningen till att 90 % av implementeringarna av ERP-system misslyckas. Förespråkarna för involvering av användarna för lyckad implementering är många. I denna studie har vi belyst en fallstudie i en relativt liten livsmedelsorganisation där det har studerats vikten av kommunikation och kommunikationsrutiner för att ta till sig ett nytt system samt hur detta har påverkat organisationens anställdas 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 innebära större acceptans hos användarna, då de får förståelse för varför saker och ting sker samt varför deras arbetsuppgifter ser ut som de gör, en kontext kring sina aktiviteter. Vi fann att kommunikationssättet, det vill säga huruvida den var formell och rutinartad eller informell, inte påverkar utfallet av användarnas acceptans gentemot ERP-systemet, så länge kontexten för aktiviteten förmedlas.

Involuntary childlessness is a big problem around the world. One way to solve the problem is to receive oocytes or semen from a donor. In Sweden, semen donation has been regulated by law since 1985 and oocyte donation since 2003. The aim of this study was to investigate what motivations women and men in Sweden have to donate gametes, if they feel any ambivalence to donate, and to compare if there is any difference in motivation and ambivalence between women and men. Motivation was measured with eight statements based on previous results and clinical experience.
