This paper analyses the potential extent of labour mobility in the European Union after the eastern enlargement that took place in 2004, but focuses on movements from the 10 new member countries to the old EU -members. In this study, a number of economic models are used to investigate if there is a large potential for labour mobility in the enlarged EU and also if this potential has large effects on mobility in reality. The potential for labour mobility is, to a large extent, discussed in terms of theoretical migrating incitements for workers and different types of labour migration obstacles. Many factors indicate that such large potential for migration actually exists, mainly due to high difference in wages and unemployment and because of the common EU market. At the same time, the presence of natural and constructed obstacles is likely to restrict migration for a long period of time..

Turbulens är ett väderfenomen som har orsakat många olyckor och incidenter. Speciellt farligt är klarluftsturbulens eftersom fenomenet ej är synligt för blotta ögat, samt att det kan uppstå mycket plötsligt. Mycket pengar och resurser har lagts ned för att ta fram system som skall kunna detektera och automatiskt rapportera turbulens. Denna uppsats beskriver kortfattat hur några av dessa system fungerar samt hur systemen skall bidra till att piloter lättare skall kunna förbereda för eller undvika turbulens. Uppsatsen beskriver system för prognostisering, detektering och automatisk rapportering av turbulens med tyngdpunkt på klarluftsturbulens..

Utvecklingen från jordbruks- och industrisamhället till det moderna informationssamhället har medfört stora förändringar i de sociala systemen vad det gäller grupprocesser och interpersonell dynamik. Sett ur ett komplexitetsperspektiv kommer de tätt kopplade agenterna i de tätt kopplade systemen att uppvisa interaktionsmönster, som skiljer sig från tidigare historiska epoker med dynamiska processer unika för tidevarvet. Syftet med detta examensarbete är att, via en litteraturstudie, beskriva och problematisera individens förutsättningar för identitetsbildning och ontologisk säkerhet i komplexa sociala system. Resultaten visar att komplexa sociala system kännetecknas av självorganisering, som kan resultera i att komplexa strukturer/egenskaper växer fram på en högre nivå. Den semi-autonoma agenten kan även konceptualiseras som ett komplext system, i sig, som påverkar, och påverkas av, de mångfaldiga komplexa sociala systemen.

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

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 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.

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 dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

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?.

The aim of this study is to analyse how female neopagan practitioners form their identitiesindividually as well as collectively. Using Ernesto Laclau?s and Chantal Mouffe?s discourse theory and Anthony Giddens? descriptions of late modernity and self-identity, I intend toinvestigate my informants? construction and upholding of a meaningful identity and sense ofself. I will also look at how the neopagan movement can be viewed as a phenomenon closely interwoven with the overriding tendencies in our contemporary society. Neopaganism is an umbrella term that is used to describe a number of modern nature religions that take their inspiration from pre-Christian traditions.
