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.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

A new line of business has arisen on the Swedish information market. The information broker is still quite an unknown actor but the future seems to hold a prosperous outcome for this kind of alternative information service. The information broker has many definitions but can generally be described as an intermediary between information sources and users. The Swedish market for this kind of information professionals has not yet developed into a big, well-established and lucrative branch as for example the one in the USA. The Swedish actors are still coping with resistance in form of insufficient support from the government, competitiveness from other more established information services and the clienteles lack of understanding the brokers purpose and utility.

The purpose of this study has been to investigate how individuals with reading- and writing disabilities and dyslexia handle their information need in the workplace. The method that has been used is a qualitative study made with interviews with individuals who have these problems, to see how they think and feel about the flow of information on their everyday basis. The study?s respondents are working women between the ages of 27 and 47 years old and they have reading- and writing disabilities and dyslexia. The most interesting results of this study are that the respondents are avoiding jobs where they need to read and write much and where they also do not like changes in their job situation.

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.

This thesis analyzes the consequences of ?Lex Uggla? ? a law concerning the boundaries between firm and individual with respect to wealth taxation ? for small businesses, with more than 3 million SEK in over-liquidity. There are two main findings of this thesis. Firstly, the wealth taxation of non-operational assets seems to be an inefficient tax which costs the Swedish welfare system much more than it generates. Secondly, the change in actions among entrepreneurs following the extensive news coverage following the tax authority?s charges against the company of the well-known artist, Magnus Uggla (hence ?Lex Uggla?) illustrates that neither changes of rules nor new applications of rules is necessarily sufficient for an agent to change course of action.

The purpose of this thesis is to show students? information behaviour in everyday life and towards the Student Union of Borås. Methods of active information seeking and more random information encountering as well as information ignorance are of interest. The study focused on three issues; the first was to examine what information behaviour the students presented while acquiring information in their everyday life. The second was to find out what information behaviour the students had to acquire information from the Student Union of Borås.

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.

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.
