This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

The Swedish Institute is a public agency promoting Swedish interest, national image and confidence around the world. This work attempts to investigate how communication and a process over time influences and effects public diplomacy. The analytic discussion is based on a single case study research of this Institute representing ideas in the international science field of public diplomacy. The theoretical ideas of public diplomacy are placed in a theoretical perspective of social constructivism. The method is qualitative, with excerpts taken from interviews, literature, newspapers, articles, state public reports and social media.

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

The Swedish Government has decided that Wind power should have a higher contribution to the electricity generation in Sweden. Their goal is that, by 2015, the yearly production by Wind power should generate 10 TWh. In year of 2006, the 760 wind mills in Sweden generated only 0,936 TWh. Despite good wind conditions in a large extend of Sweden's land- and coast areas, the slow rate of new wind mills establishments will likely result in unattainable goals. The major problem for new establishments of wind mills is the extensive and complicated permission process. An expert group of environmental studies (Expertgruppen för miljöstudier) was commissioned by the Government to make a report concerning the problems with the expansion of wind power in Sweden.

This essay examines the persuasive side of music and its affect on consumer behavior when utilized in television commercials. It includes an interpretation of twelve study cases, in which three groups of four people is presented the same commercial, with different music being the only item dividing the groups. This is followed by a few questions about the product. The aim is then to see how the answers differ from one group to another, and how they match the music?s presupposed connotations suggested in the theory part of the essay, thus, observing the communicative, and eventually persuasive, power of music in television commercials.

With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-conventional methods of energy conservation. Building Earth sheltered houses is such a method.Earth provides good insulation and provides the ability to both reduce the total heating needs and toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering.

Syfte Syftet med föreliggande studie var att studera korrelationen mellan EMG-respons och effektutveckling i samband med genomförande av knäböj.MetodFyra manliga testpersoner deltog genom att utföra både knäböj 90° och djupa knäböj i en Smith-maskin som är ansluten till en Linear Encoder som möjliggör beräkning av effektutveckling. Samtidigt registrerades elektromyografisk aktivitet i musklerna Vastus lateralis, Hamstrings och Gluteus maximus. De utförde knäböj på olika relativa belastningsnivåer; 20, 40, 60, 80, 100% av 1RM.ResultatResultaten visade inte en stark korrelation mellan medel-EMG och power, inte heller mellan medel-EMG och hastighet, dock indikerade resultaten mellan de sistnämnda en tendens till att en lägre EMG aktivitet uppstod vid de högre hastigheterna. En starkare korrelation kunde antydas mellan medel-EMG och belastning/kraft. Ingen tydlig skillnad mellan musklerna påträffades i förhållande till resultaten ovan.

Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.

Gtherm is an innovation company who has an unique air heat exchanger underdevelopment. The purpose of this thesis is to provide data of suitable motors for theheat exchanger and to find suitable motor suppliers.A motor specification was designed. It is an important basis for the search of suitablemotors. A compilation was made of nine motor suppliers and the suitable motorsfrom those. The compilation can be used by GTherm in their choice of suppliers andmotors.The compilation of the demands on the motor and analysis of suppliers indicated thatthere were no standard motors available to GTherms air heat exchanger.

The aim of this study is to explain and analyse political steering of public libraries in Swedish municipalities and the roles of politicians and administrators in this process. To fulfil this purpose five municipalities have been studied. It is argued that both politicians and administration have to be included in a study of steering and that the relation between politicians and administrators should be seen as an interplay. Planning and evaluation are discerned as the two main activities in the steering process. The material in this study consists mainly of information collected through interviews with library responsible politicians and library managers in all five municipalities.The results show that libraries are considered politically uncontroversial and that politicians see little need for political interference and steering.

Background: Power by force and threats used to be the common way to collect taxes, but this procedure is today completely different. It?s now more about building a mutual relationship and with help of laws and controls steer citizens and companies to pay the tax they owe. Thus the way to collect taxes have changed over the years, the collecting of taxes aren?t a popular task to do.

The aim of this study was to, with a social constructivistic approach, examine how parents,regarded as neglecting their children, are depicted in 12 LVU-legal cases from the Supreme Administrative Court in Sweden. By using a document analysis influenced by discourse analytical tools, we found that there are repeated descriptions of the parents, which constructs an image of parents as shortcoming in the care of their children. The categories lack of emotions, mental disorder, substance abuse and physical maltreatment were the main reasons for child neglect that the parents were described from. Attitudes towards authority, aggression and immaturity, lack of insight, and deficiencies in the home were repeated in the description of the parent. We further found that mothers were regarded as more responsible of the children compared to fathers.

In this study we have explored and investigated how journalist experience the relationship with politicians/press secretaries in the making of political news. The study examines how journalists see the balance of power between them and their political sources in the setting of the news agenda. To do this we have used a qualitative interview analysis. Our theoretical starting points have been based on the social exchange model. The social exchange model has a social psychological and sociological perspective that explains the interaction, social exchange and stability as a process of negotiation exchanges between parties and operators.

The purpose of this essay was to investigate socialworker's perception of threats and violence in their daily work from the perspective of power. In order to obtain as clear and distinct responses as possible, I used qualitative interviews for this study. The respondents represent a "socialförvaltning" that handles financial assistance in a medium-sized city. This department was chosen because the socialworkers that handle financial assistance at this department have been identified by the media as particularly vulnerable. The study showed that verbal threats are commonplace but physical violence is rare.

Through a critical discourse analysis this study explores the gender norms that students on Kvinnofolkh?gskolan produce, reproduce and experience. Kvinnofolkh?gskolan is built on the understanding that the world discriminates against women politically, culturally, economically and socially, and thus intends to give women, non-binaries and trans people an education with a feminist alignment. Despite studies being made on gender segregated schools as identity forming, I argue that there is a lack of studies that show how gender discourse and theory is produced in contexts where men are excluded.
