This Master Thesis discusses the development of bids for regulation power with consideration of change of discharge. The study was initiated by Vattenfall PD and is a limited part of a substantial development project at the same division. The background of the project is the new demands from SvK, which among other things includes more detailed regulation bids. As from the 1st of November 2008, the regulation bids are supposed to be calculated regarding each specific regulation object, something that is defined by SvK. These new demands changes Vattenfall?s conditions and will increase the need for detailed knowledge about available regulation power and costs for regulation.In this study a strategy for regulation bids was developed.

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

In this study, the aim is to show how the social services fails to implement a specific rights law (LSS) wich is supposed to have the function of protecting the wellfare and provide specific rights to people with severe mental disabilities. By applying chritical theory on this case the aim is to provide an alternative answer on why it is possible for the social services to ignore these peoples rights.By revealing the power structures in the encounter between the system and a person with mental dissablilities, I conclude that people with mental disabilities does not fit in when it comes the social sevices way of implementing the law and further more that a private person is extreamly exposed to the systems arbitrariness..

The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.

The purpose of this thesis is to examine how power structures concerning gender and sexuality emerge through the use of language in the Swedish reality show Paradise Hotel. Of particular interest is the representation of heterosexual relations in the show. Because of its interest in the relationship between power, gender and sexuality, the thesis is based on theories from gender and discourse studies. The specific theories referred to are Michel Foucault?s understanding of power, stereotypes according to Stuart Hall, Yvonne Hirdman?s gender system and contract theory, Judith Butler?s heterosexual matrix and R.W.

The purpose of this paper is to explore the social worker?s perspective on working for the government as a professional in care of children, in relation to the family's right to self determination. The essay's empirical material is gathered from qualitative, semi-structured interviews with social workers who work with children and youth in communities and districts in Skåne and Stockholm City, Sweden. The analysis was conducted in line with theories of social constructivism. The results and analysis show that the interviewed social workers did not believe that the state has too much power over the citizen.

On the 8th of May 2007 a local power-sharing goverment consisting of Sinn Fein and the Democratic Unionist Party (DUP) was formed in Northern Ireland. The aim of this dissertation is to explore why the DUP, who in the past have opposed all forms of power-sharing decided to form a goverment and take active part in a power-sharing agreement. The study is based on a consociational theoretical framework developed by Arend Lijphart and further developed in a Northern Irish context by John McGarry and Brendan O'Leary. Using this theory the study seeks to understand the broad conditions surrounding the DUP's power-sharing. After a description of consociational theory and the road leading up to the Belfast Agreement,three possible explanations for power-sharing, based onconsociational theory are discussed.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

This thesis analyses the 2005 UK presidency of the Council, and more particularly the negotiations on the future financing of the European Union. The purpose of the study is to discuss whether the holding of the presidency implies political influence for the member state. To analyse the power of the country holding the chair the thesis focuses on the presidency functions of brokering and leadership. The theory suggests that the influence of the presidency is derived from informational and procedural power resources, as well as some leadership resources, such as coercion and reward. A case study was used to analyse whether these power resources were used by the British presidency.

The aim of this investigation work " What was it called...Equality...? is to study a clinics current gender equailty plan from a gender approach and by a field survey see if, and in that case, how it can be improved. A connection between existing gender norms and gender power strukctures is applied in the results of this survey in order to illustrate their significance from an individual as well as a structural perspektive.The survey has been carried through by a field survey as well as a discourse analysis as method. Yvonne Hirdmans gender power system is on of the main theoretical points of departure.The results that I have achieved in this essay is that gender can be looked at in different ways within the labour market where women have the main responsibility over the family and are considered more nursing then men. Men on the other hand are thinking of their carriers and have higher salary requirements.

With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.
