Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

This is a 20 credit Master thesis within the landscape architecture education at the Institute for Landscape Planning at the Swedish University of Agricultural Sciences at Alnarp. Norränga is situated on the fringe of the city of Lund, east of the existing district of Linero.The city planning office of Lund municipality has come up with a ?in-depth comprehensive plan? for the exploatation of the eastern area of Lund. The plan concerns an area of 1035 square kilometre which contains at least 1500 nya buildings, two schools, primaryschools, stores and bus station for local bus traffic and the new bus line - Lundalänken. The townplan is inspired from the historical Square block city with defined street system. The municipality has visions of what the green areas should consist of.

AbstractPurpose/Aim: This essay deals with The Swedish Red Cross Society and their work concerning strategical information and communication about HIV and AIDS in the Swedish context. In a broader sense the relation between the global and the local will be investigated and a discussion about what it means to work in an organization operating on a global arena will be held.Material/Method: This essay is based on relevant theories about culture and health communication which I have studied, selected and put together, with purpose to analyse The Swedish Red Cross Society and their informational work with HIV and AIDS- prevention. Furthermore I have interviewed four of the organizations co- workers to collect data about their experiences in working in the Red Cross organization with this specific mission. Moreover I and my colleague Hillevi Good attended at seminars and lectures to observe activities held by the organization and to get inside information about what people working with HIV and AIDS are discussing and considering as critical issues. The study holds a qualitative approach focusing on understanding this typical case rather then generalizing facts in a larger sense.Main results: The Swedish National Society of The Red Cross has a difficult mission in their work to inform the public about HIV and AIDS, although it is the perfect organization when it comes to communication due to their well-known profile and a huge geographical spread.

It is clear that media advertising is one of the crucial marketing tools for companies in order to promote their products and services. As we are moving towards more and more economic integration, both on a regional and global scale, the question about standardisation of media advertising has become increasingly important and is nowadays subject to discussion in most international companies. This thesis deals with the issue of standardisation in a region where the process of political, legal and especially economic integration is taking its course, but where cultural and linguistic diversity is still a remaining fact: Europe. The aim of this thesis was to investigate the potential gains from a standardised advertising approach but also to identify its limitations. Especially on a market place like Europe, with its diverse cultural and linguistic background, a fully standardised approach might be difficult to implement.

The thesis is about exploring possibilities for developing a standardised system solution for micro businesses, this since most of the micro business lack proper system solutions, a contributing factor of this is price and also incompatibility between the solution and the business itself. The system solutions we will refer to are solutions which task is to cover the most important needs that a micro business might have on their system. The main goal with this research is to see if this is possible, and if so, how the developers should think to take it further. We chose to do this by identifying the most significant of needs a micro business has when it comes to this type of system solution.In this thesis we will present three needs which were evaluated and brought forth through the analyses of various interviews and observations we had done during the study. The interviews took place at respective company with their employees and consisted both closed and open questions with our main focus on the open questions because we wanted to obtain as much information from the respondents as possible from several viewpoints.

The aim of this Master's thesis is to discuss and analyse co-operation between public and academic libraries. The political changes that were initiated during 2004 have come to alter the conditions for Swedish libraries. The Swedish library law was changed at the 1st of January 2005 and co-operation between libraries is now statuary even if there is no description of how the new mission is to be executed. At the same time an extensive report about the Royal Library and its role as the Swedish National Library was presented. This report also recommended an increased co-operation between different types of libraries.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Virtualisering av datorer rent generellt innebär att man delar upp hela eller delar av enmaskinkonfiguration i flera exekveringsmiljöer. Det är inte bara datorn i sig som kanvirtualiseras utan även delar av det, såsom minnen, lagring och nätverk. Virtualiseringanvänds ofta för att kunna nyttja systemets resurser mer effektivt. En hypervisorfungerar som ett lager mellan operativsystemet och den underliggande hårdvaran. Meden hypervisor har virtuella maskiner sitt egna operativsystems kärna.

The costs of logging and of transportation with truck are dominating the total cost of wood delivered at industry. To support the profitability for the members' forestry the processing and handling with the timber has to be as efficient as possible. Increased length of pulpwood in thinning is one conduct that can result in higher productivity and/or lower costs. The study is scaled as a system analysis with the aim to exemplify the differences between working with 3- and 4-meter as standard length of pulpwood, related to biological aspects, timber receipts, cost of logging and cost of transportation with truck. Important aspects are if the change is technically and biologically feasible and economically profitable.

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

An uncountable number of companies are present in foreign markets as a result of what we commonly choose to call globalization. This is especially true for Swedish companies traditionally operating on small markets. A company that is about to establish on a new market is faced not only with possibilities but also with challenges and risks. Researchers have found that companies that establish on foreign markets will have to deal with competitors on the national as well as on the global market, and therefore need consider how they globalize their brands. In addition to this, a brand can only reach international success if its message is coherent within and across every single market.

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

En operationssjuksköterska kan under sin yrkesverksamma tid förväntas att ansvara vid en operation där patienten konstaterats hjärndöd och det beslutats att organdonation ska genomföras. Syftet med denna studie var att beskriva operationssjuksköterskors erfarenheter vid organdonation när donatorn är hjärndöd. Studien har en kvalitativ ansats, där forskarna strävar efter en helhetsförståelse av det studerade intresseområdet. Datainsamling utfördes via ostrukturerade intervjuer med öppna frågor. Sju intervjuer genomfördes med operationssjuksköterskor som medverkat vid organdonation när donatorn var hjärndöd.
