This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

Media has the power to influences society. Some call them the third power of a state. Through amongst others, the agenda setting theory and the framing theory, this report seeks to understand how media describes the swine influenza and how it uses its power to influence people to vaccinate. As this report will show, there is no doubt that media has had an impact on the Swedish population of which 60 per cent followed through with the vaccination. Media used an information discourse and attempted to present its articles in an impartial manner and used governmental authorities and experts to support its arguments.

To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.

This thesis examines how online fashion retailers utilize blogs and other social media in their marketing process. The study is focused on internet retailer Nelly and how they make use of fashion blogger Kenza in their marketing. Drawing on Kawamura?s fashion-ology theory, the study emphasizes the new role of the fashion bloggers in the fashion system, and illustrates their consumption power vis-a-vis the retailers, the consumers, each other and the whole industry as such.    .

The purpose of this study is to investigate the way George W. Bush used the language as a means to exercise power in an attempt to justify Operation Iraqi Freedom. The theories used to answer the purpose are discourse analysis and three different moral metaphors that are applied on the data.The collected material for the metaphors is constituted of cognitive linguistic books from prominent linguists, such as George Lakoff, Alan Cruse and William Croft, and the material for the discourse analysis is also collected from prominent discourse analysts such as Michél Foucault and Norman Fairclough. The official White House website provides the material for my data. The scientific method used in this study has been qualitative text analysis where the hermeneutic approach has been an essential part of it.The main question: In what way did George W.

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

Energy efficiency is today more important than ever, mainly due to the high energy prices and the approaching climate changes. Heating of buildings is an essential area within energy efficiency. Many buildings are old and were built at a time when the energy prices were low and the term ?energy efficiency? was unheard of. By applying today?s broad range of energy saving actions on these old, and thereby often, heating ineffective buildings, this area has a large potential in reducing energy consumption and costs.Churches and chapels are generally old buildings with, in many cases, ineffective heating systems and therefore consume much more energy than needed.

Can the Danish "Aftalesystemet", a system with the intention to simplify the use of services within health care, be used in Sweden? This project has investigated the possibility by installing and testing the system and explored its functions to detect any eventual problems. Analyses were made of the system's graphical part and the underlying code to see in greater detail how the communication between units occurred, since no actual documentation of it existed. Discussions with the developers took place regarding how the current system works and how further development should continue. In order to test the system, a completely virtual environment was used.

Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

Syftet med projektet har varit att skapa en generell investeringsmodell för att ekonomiskt utvärdera ett antal mätinsamlingssystem. I rapporten har Milabs, Seneas, Enermets, HM Powers, Iprobes samt Techems och Viterras system analyserats.

This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles.
