Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
I linje med styrdokumenten? - en fallstudie i tre läromedel i engelska
This study focuses on an analysis of three text books in English, Prime Time, Second Time, and Third Time, written for Swedish pupils between grade seven and nine. The main focus of the study is to investigate to what extent the books may be considered to follow the steering principles of the Swedish education system. The theoretical backbone of the essay is centred on the construction and maintenance of stereotypes, and is written from a social constructivist point of view. In this context, I also reason around power relations and norms in the Western society ? arguments which I, in the main analysis, apply to the books in question.
Komponentuppdelning av elnätetpå lokalnivå
Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.
För Sverige i tiden? : En studie om den svenska monarkins relation till samhället och sekulariseringsprocessen mellan 1858-2012
Christendom has under a long period of time in Swedish history been the central component in legitimating the monarchs' power, a continuous process than can be clearly observed through the customs of royal coronation and baptism rites. However, during the 20th century those close ties between the state and the church of Sweden have been dissolving at a steady rate, alongside a growing societal democratization and modernization process. Officially the monarch still had a clear constitutional power legitimated through the transcendent, but unofficially his power was in reality heavily reduced. How do the Swedish monarchy relate to a rapidly changing society and secularization process? This pilot study investigates this relation by analyzing the news reports of the royal coronation and baptism rites between 1858 and 2012 from two leading newspapers, Aftonbladet and Dagens Nyheter.
Materialdistribution i ett tillverkningsföretag : en fallstudie av PartAB
The purpose of this project is to study Partab's material distribution process, furthermore identify critical problem areas within the company. Further the aim is to provide suggestions to new work procedures regarding material distribution and related processes. Appropriate literature has been used as a support in this process.
The main goal of a commercial company is to generate cash flow, and maximize the return on investment. Streamlining material supply and the use of material is a part of this process. Virum and Persson define logistics as: "Logistics is the approach and principles founding the process of planning, development, coordination, organisation, management, and control of material distribution from supplier to user".
Design av försöksanläggning för trycksatt rökgasrening vid oxy-fuelförbränning
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Bilder av Sverige i Italien
Title: Images of Sweden in ItalyNumber of pages: 5252 (589 including enclosures)Author: Oskar GustafssonTutor: Martin NilssonCourse: Political Science C level ? Bachelor?s ThesisPeriod: Spring term 2010University: School of Social SciencesLinnaeus UniversityPurpose/Aim: The purpose of my research study is to, through the use of political science theories on soft power and marketing theories about nation branding and in comparison to previous studies on the image of Sweden in Italy, gains a better understanding of the image of Sweden in Italy, with special focus on national political institutions and young Italians.Method: The method of analysis is a combination of qualitative methods: interviews where information about the image of Sweden amongst national political institutions were gathered and a survey where information was gathered about the image of Sweden amongst young Italians.Main results: On the basis of the results I have gained it can be concluded that a positive and well informed image of Sweden emerges when it comes to cultural and social factors but a more restricted and somewhat negative image come to light when asking national political institutions and young citizens in Italy about their views and knowledge on Swedish domestic and international politics and economics.Keywords: Soft power, Public Diplomacy, Nation Branding, Images of Sweden, Italy..
Informationsfrihet och IT-användning i demokratifrämjande syfte
The potential of information technology as a means to invigorate democratic practise is constantly under discussion. Regardless of the differing opinions as to the most suitable way to utilise IT, there are certain democratic core values that have to be considered. One of these is freedom of information, defined by us as the right of every citizen to seek, obtain and express information. The aim of this study is to explore whether the use of IT as a means to enhance democracy can strengthen the citizens right to freedom of information. As an instrument for analysis we use an article by Jan van Dijk, professor of communication science.
Empowermentprocesser på ett screentryckeri : en studie av det sociala arbetskooperativet Young surfers
The purpose of the study is to investigate the significance of organizing social- cooperative in relation to individual empowerment; and how this empowerment can be used to better the situation of others. Young surfers is a social- cooperativ that is run by cooperators with experience of substance abuse and criminality. The social- cooperativ is built on the premise that the cooperators are to set up and run a screen-printing shop where they will print t-shirts and sweatshirts. The purpose of this business is that the cooperators are given the opportunity to work and that youths with social problems such as substance abuse and criminality are given the opportunity to work-train. My study is comprised of a series of interviews and observations that I have conducted in relation to the cooperators of Young Surfers.

This study is intended to study how the social worker in financial assistance relates to the social workers exercise of its authority, regarding the Social Services Act and the Administrative Procedures Act. In concerning how the social worker treats and handles the cases of their clients, but also what significancethe organization's policies and goals have on the social worker?s role and the formation of their professional identity. To answer these questions the study chose a qualitative approach. Because the purpose of this study is to investigate the social worker?s personal beliefs about their way of conducting social work.
Animal welfare in Ethiopia : transport to and handling of cattle at markets in Addis Abeba and Ambo
Stressful routines for animal handling can reduce immune function and productivity of animals. If stakeholders are handling animals aversively, animals will show increased
expressions of fear for humans and higher stress levels which lead to the compromise of animals? welfare. In Ethiopia, there are no legislations to protect animals from suffering or discomfort. The main objective of this study was therefore to analyse welfare of cattle on animal markets in Ethiopia and map out supply chains of animals to these markets.
Lärare och skolbibliotekarie ett udda par som bör dra jämnt. En studie i samarbete på en högstadieskola
This Masters thesis concerns collaboration between teachers and librarians. Three theoretical perspectives, profession, power and legitimacy, are used to analyse the results of written interviews with eight teachers and one librarian at a comprehensive school. We did not find evidence of any deeper collaboration between teachers and the librarian. The effects of profession had little impact on the relation although the involved parties seemed to appreciate differences in education and points of view. The teacher retains power over education and grades while the librarian holds sway over the physical library and the purchase of books and other media.
Utvecklingsarbete, Sagor : Läs- och skrivutveckling under ett sagotema
This thesis has the purpose that through a text analysis examine how four schoolbooks for high school treats the religions Judaism and Hinduism. The schoolbooks are from the years 2000, 2001, 2003 and 2009. The perspectives are from a religious viewing point, that means that the women are religious, Jewish feminists and Hindu feminists. The theories used are written by these women and are academic litterature. The questions are how are women represented in the schoolbooks, is the feminist critique present or are the two religions represented and described in an invariable way, and is the description of Judaism and Hinduism consistent with the curriculum?The text analysis used in this examination means that reality is organized through and by the language used by the actors in that reality.
Investeringsprocesser i storbanker : en undersökning på tre svenska storbanker
There are no general working processes that can stand for how all the investment process is preceded in the organization of major Swedish banks. It is not a question of investment process but rather a question of, investment processes. How these investment processes operates depends totally on the type and size of the current investment, which unit that is operating the processes and what situation the bank currently finds itself in. There is a written form that describes how the different processes should be operated and which capital budget models that should be used but the usage of these forms can be questioned..
