Ny princip för spänningsreglering i Fortum Distributions mellanspänningsnät i Stockholm.

The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.

Motivation is a key factor for maintaining a healthy lifestyle and together with the help of today?s modern technology, facilitating new innovative approaches has made it easier to motivate people towards regular physical activity. This study aims to examine how a training application can increase motivation and how behavioral change occurs when using a training application. Qualitative data collection methods such as interviews and observations have been used in this study.

Kvalitetssäkring av servicelämnare för skogsbrukets arbetsmaskiner : Intervjuer och förslag till utveckling

In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..

Att veta Gudarnas hemlighet : En sårbarhetsanalys av omständigheterna kring stormen Gudrun med pressure and release modellen

The concept of vulnerability is the capacity or the sensitivity to become damaged. Vulnerability are characterized by one or more of the following terms; a system´s sensitivity to exposure to shock, stress or interference, the state of the system in relations to a threshold of damages, and the system´s ability to adapt to the changing circumstances. Vulnerability in this study is referring to the sensitivity of the circumstances that lead to sustainable livelihood that can´t be maintain and that there is an inability to cope with and manage stress. The choice of making a study in this area is based on that action needs to be taken to moderate the vulnerable aspects of society, in this respect in relations to storms. Analyzes of the social vulnerability to climate change or natural events is needed for effective actions.

Bevarande av webbplatser : En kartläggning bland statliga myndigheter i Sverige

The purpose of this thesis was to investigate if Swedish agencies preserve their websites according to the Swedish archival legislations and guidelines. As a theory the OAIS Reference Model (Open Archival Information System, developed by US Consultative Committee for Space Data Systems, CCSDS) has been used as a model to show how important it is to develop strategies for public digital information which has to be preserved for long term. The ingest function in the OAIS Reference Model demands that files are prepared for long term preservation and requires that the digital information fulfils established technical requirements.In the study the Swedish National Archive and their advices about preserving websites to archivists on the Swedish agencies are being studied. To control if the agencies meet the requirements for their management and preservation of their websites a survey was sent out to investigate if Swedish agencies preserve their websites. According to the survey result, 84 of 113 agencies preserve their websites in some way. If the technical requirements really was met could not be verified in this thesis, the results was relied on the responses from the authorities.

This report describes the construction and development of a control box, which is a tool for testing and verifying a certain model of Rapid?s built in staplers (model A6102). Basically the function of the control box is to interpret any errors that may occur in the stapler and to make it possible to test fire the stapler.The control box should be able to communicate with the stapler using a specialized communication protocol. The different data such as errors, firmware etc. from the stapler is presented in plain language on a display.

Svartgran ? ett alternativ när allt ser mörkt ut? : en kartmodell för att visa lämpliga ståndorter för odling av svartgran

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.

Brittiska Labour ? svikare eller frälsare? : Om ett svikt vallöfte eller en räddning av Storbritanniens inflytande i EU.

This Bachelor thesis deals with the act of the British Labour Party when they recalled a referendum promised by former Prime Minister Tony Blair. Tony Blair promised a referendum on the Constitutional Treaty, but his successor Gordon Brown later recalled it when the Lisbon Treaty succeeded the Constitutional Treaty as the legal foundation of the European Union.The main purpose of this thesis was to with help from various theorethical frameworks explain why the Labour Party decided to do this, even if this decision gave the main opposition party, the Conservative and Unionist Party (the Tories), the chance to heavily critisize the Labour Party, and picture them as traitors.The research questions were:? What are the reasons that the Labour Party went from being a Eurosceptical party, to become more pro-European?? Why did the Labour Party cancel the promised referendum on the new treaty of the European Union?Various answers were found for the first research question. Among the most important was that it was a part of the over all transition which led to the launch of New Labour.The second research question was answered with three explanatory models based on actions of the Labour Party on three arenas; the electoral arena (based on power, this model claims that the Labour Party act as they do because the know the Tories would not act differently if they were in office), the parliamentary arena (based on ideology, this model claims that Labour want the Lisbon Treaty because it has a stronger social dimension than earlier treaties) and the internal arena (based on the problem of identification, this model claims that the Labour Party identifies itself with the British government, and not just the voters, and are afraid of damaging Britain?s influence in the EU and international politics if Britain says ?no? to the Lisbon Treaty)..

Mode, platser och varumärken : En studie om betydelsen av försäljningsplatser för modeföretag och deras varumärken

In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.

Någonting mystiskt händer i Sjumilaskogen: En kulturpolitisk analys av TV-reklam riktad till barn på TV 4 och Kanal 5

The aim of this Masters thesis is to review Swedens unique law against TV-commercials intended for children under twelve years old. The law has to be abided by TV 4, but not by Kanal 5, so the aim is also to compare TV 4 and Kanal 5 and to see in what different ways commercials are shaped in the two channels. The cultural policy analysis is based on our aim and problem. We have also had the terms semiotic and intermediality in mind together with a model made by the researcher in semiotics Roman Jakobson. The model consists of six different communicative functions.

Influence of the habitat on the potential for cannibalism and population dynamics in stream-dwelling European grayling (Thymallus thymallus L.)

Cannibalism can have major influence on fish population dynamics. A prerequisite for cannibalism is that the cannibal and the potential victim meet, and besides density effects, the encounter rate between cannibals and their victims is therefore also largely dependent on habitat use and habitat heterogeneity. In this study I quantified and compared the potential for cannibalism in stream-dwelling European grayling populations in three rivers in Jämtland by means of habitat classifications. I also analyzed population dynamic consequences of varying the potential for cannibalism in terms of intensity, using a physiological structured population model. Findings based on habitat characteristics were that the potential for cannibalism is in general not favourable in these types of streams.

Utformning av sidoområden med hänsyn till vägens livscykelkostnad

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.

Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Leder kritisk publicitet till kritisk publicitet?

Academic research indicates that critical publicity can have a detrimental effect on brand attitudes. The negative effects have been showed to be buffered by cognitive bias elicited by strong favourable attitudes, commitment, brand certainty and brand identification. It has been proposed that the influence of such bias in a news reporting context should be studied, something that also is interesting from a brand perspective. The study therefore investigated whether a well-publicised scandal in one period can lead to increased critical publicity in the coming periods. A case study of Swedish grocery chain ICA was conducted.

Vem använder budget? : En kvantitativ undersökning av budgettillämpningen i olika organisationer

Weber and Linder (2005) have enlightened that the focus of the current debate on the budget?s to be or not be, has been on trying to find a general tool, which fits best in all situations. They argue that the budget may be more appropriate for organizations in certain circumstances, than for others. They claim that there is a gap in research concerning the situations in which the budget may be appropriate, or when Beyond budgeting is preferred. It is this gap we are trying to fill with our thesis.The purpose of the thesis is to explain which situational factors that affect the organization's use of budgets for the functions the budget can fulfill.
