Softube has developed DSP-card and software for simulation of the sound of old tube amplifiers. The purpose with this thesis is to design a compact amplifier with high power to function together with the DSP-card and build a unit that can replace several other guitar amplifiers. The advantages with that kind of solution could be that it would be cheaper, easier to carry and easier to stor than the real amplifiers. The amplifier that has been designed is of class D type with digital PWM modulator. There is several types of amplifier modules on the market that use analog input signal, but if one of them would be used a D-A converter is needed on the DSP card.

The aim of this Master´s thesis is to examine the debate in Swedish library press concerning outsourcing of public libraries. The two magazines studied are BBL (Biblioteksbladet) and bis (bibliotek i samhälle). The period of time covered by the selected articles is 2005 to 2011. Although there are still quite few cases of tendering arrangements in Sweden, the question has been raised in the last years by the decision of the Municipality of Nacka (Stockholm) to outsource their public libraries. Another important factor for bringing the question into focus has been the general elections of 2006, which brought an alliance of right-wing parties to power.     In this thesis the arguments of the participants are documented and analyzed.

As companies grow, their need for computing power will increase, which traditionally resulted in companies having to invest in more IT resources. Now, with cloud computing, companies can easily hire computer power over the Internet, on-demand. Cloud computing offers a highly scalable environment where companies can store data and host their services. This paper employs a qualitative study with interviews and literature studies to explore opportunities and challenges associated with cloud computing from a system developer perspective. The aim of the paper is to find out how cloud computing changes the conditions for system development. The paper contributes with four different opportunities and challenges that the system developer must handle to succeed in the world of cloud computing.

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

This paper is a discourse analytic policy study with the intention to investigate the swedish government's policy action plan against prostitution and trafficking for sexual purposes. The document is called Handlingsplan mot prostitution och människohandel för sexuella ändamål. The purpose of the study is to investigate whether there is a feminist gender understanding taking place in the action plan. This is made by both see how the problem of prostitution is produced partly by examining whether there is a gender-based power analysis in action. The research questions of this study are:What is considered being the problem with prostitution and trafficking fosexual purposes?Is there a feminist gender understandning in the government's prostitution politics?To answer these questions I use Carol Bacchis method Whats the problem represented to be? And the material being used is the government's actionplan.

The aim of this M.A.-thesis in social work is to problematize the assimilatoric concept of integration and its discourses in a postcolonial perspective in relation to social work in Denmark.As a support theory I use symbolic interactionism. By using these theories I show how the concept of integration and its discourses, when its aim is assimilatoric, can be understood and problematized with concepts as binary oppositions and hegemony.It is shown that the construction of the discoursive other is a useful term as an instrument of interpretation of power in general. The relevance to social work in relation to the social workers double powered positions, professional and cultural power to define 'the other', in social work with ethnic minorities is shown in relation to the post colonial perspective with support of symbolic interactionism. The white western world hegemony and the social workers power positions in relation to the clients fits to the theoretic frame chosen in the thesis.A second aim in this thesis is to point to new ways for social work and to the necessity to reflect over a globalized world characterized by international migration, ethnic relations and diversity..

The work thesis was performed at Assalub a company which is situated in Åtvidaberg. The company works with developing, manufacturing and marketing equipment for handling of lubricants for light and heavier industry. The work thesis it is based on a inquiry Assalub got from MacGregor which is a company within cargo solution, from port to offshore system.For unloading grain and other material from the ship cargo it is used combined inlet feeder and screw conveyor, there the inlet feeder is drilling down through the cargo and feed the screw conveyer with material to further destination. At the bottom of the screw conveyer and the inlet feeder there is a bearing that keep the parts together. However the lubrication of the bearing must be made manually.
