The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Att utnyttja flygstridskrafter har sedan tidernas begynnelse varit en effektiv metod att påtvinga motparten sin egen vilja. Sättet man använt flygstridskrafterna på har debatterats under historiens gång. Inom ämnet luftmakt finns det en rad kända och inflytelserika luftmaktsteoretiker som alla har sin idé om hur man bäst utnyttjar flygstridskrafter. Hur ser vår svenska doktrin ut gällande teorier kring luftmakt? Vilka luftmaktsteorier genomsyrar grundtanken bakom hur vi idag vägleder våra luftoperationer? Syftet med uppsatsen är att undersöka vilka generella och centrala luftmaktsteorier som återfinns i den svenska doktrinen.

The aim of this study is to create an increased understanding of shared leadership and how it takes shape in the relationship between first-line managers in human service organizations. Shared leadership is seen as a complement to the traditional one-man leadership and briefly means that two managers share the role that usually is held by a single leader. The study has a qualitative approach based on semi-structured interviews with managers in human service organizations. The interviews mention the mangers thoughts and experiences about shared leadership and gain approval in the hermeneutic science field. The study is analyzed based on symbolic interactionism where perspectives from the theoreticians Mead and Goffman are used.

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.

The purpose of this essay is to examine sfi (Swedish for immigrants), which is an ingrational-political tool with objective of teaching immigrants to read and write in Swedish. With the use of critical discourse analysis we examine the discursive practices within sfi. We also examine our methodological and theoretical approaches, and our application of them. Our research questions are as follows:? How are the discursive usage of ?person centered? and ?society centered? expressions being used?? How well does our methodological and theoretical resources work?In our theoretical viewpoint we use ?post colonial theory?, which is a perspective concerned with global Power relations seen from a historical perspective.

Literature and studies exist on how to create services in the best interest of the client or how these services have an impact on individuals. They are however mainly from a social work professional stand point and rarely from how clients would develop and create the services that can imply a life change for them. Especially when working with children under 18 years old issues of agency and age that can result in the disregard of the Convention on the Right of the Child (UNCRC). The target group of this study is therefore youth between the ages of 15 to 17 years old in three cities across Sweden to allow them to voice their opinion and experience of being in treatment. Resulting from that is the aim of this study ? to investigate how an intensive treatment method like Multisystemic Therapy is described from a client?s point of view.

ABSTRACTPurpose/aim: To clarify what information is communicated through the PR-firm JKL:s blog, how it is communicated, how it relates to and diverges from the communication theories in point, and what the strategies behind the blogging are. By doing this I hope to contribute to the knowledge on corporate blogging and how it can be used.Material/method: Qualitative textual analysis of ten blog posts published on the JKL Blog and process seeking interview with the person in charge of the same blog.Main results: JKLs? blogging coincides to the most part with business intelligence, with the exception that the information doesn?t relate directly to the company?s? main activities. This is mainly due to that they can?t publish information about their customers or competitors.

The purpose of this study is to find out, explore and see how children with neuropsychiatric problems like ADHD/DAMP are portrayed and treated in five fictional children?s books written by writers who all are related to ADHD issues, except for one writer.I have done a text analysis performed on five children?s books which can be found in libraries in most of the libraries in Sweden. The analysis shows varying results between the five books followed by a general conclusion about how children with concentration problems are being presented in these chosen children's literature. The main problematic of this study is to examine how these characters are being represented and treated within the scopes of school, family relations and how ADHD/DAMP symptoms are portrayed. This study focuses on analysing how the actual ADHD/DAMP behaviour is being reflected and better understanding for the reader to understand the symptoms of ADHD.Another fact is what kind of relations these children with neuropsychiatric dysfunctions are portrayed when facing with other persons, such as family and friends and how ADHD/DAMP is affecting them daily basis.

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 response to many on-going or emerging conflicts since the beginning of the 21st century has been different forms of multinational complex peace operations. Civil-military relations are a commonly studied field that traditionally has its focus on nations. This study intends, in the context of organisations, to test the correlation between a civil-military approach and outcome in complex peace operations. A hypothesis has been deduced from researcher Robert Egnell?s theory on complex peace operations, that states that: UN peace operations with an integrated civil-military approach are more successful in achieving their goals than peace operations with a divided approach.
