Dokumentation av underhållssimulatorer för utbildning i vardagssäkerhet
At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.
Googles varumärkespolicy : En föränddring av varumärkets värde?
During September 2010, Google decided to change their trade mark policy to allow keywords which is equal to an already own trademark to be offered to all who intend to link the word to their ad. They offered a service for this called Adwords. The update followed since The Court Of Justice (CoJ) stated that Google does not commit trade mark infringement by doing this. The question to answer is whether the proprietors of trademarks can do something to stop them from being used by competitors as keywords in Adwords. CoJ has stated that the advertisers are infringing the exclusive right of a trademark if the used keyword is identical to the trademark, the commercial focuses on products that is identical to the products which are registered on the trademark and if the commercial makes it difficult or impossible to an average internet user to decide whether the products originate from the proprietor, a company which has a financial connection to the proprietor or a third party.

With the purpose of finding the motives behind use, production and reuse of Open Educational Resources (OER), the writer has conducted a qualitative survey. The three main questions in this two years master?s thesis are:? Why do people use others? unmodified OER?? Why do people produce OER?? Why do people alter and reuse OER?The theoretic framework is built around Manuel Castells? network society, with its social and efficiency seeking dimension, along with the Knowledge commons. Some pedagogy is included as well.A web survey was distributed to 796 users of the Connexions OER repository. 95 responses were received.
Tradition, Vetenskap och Upplevelse En Analys av Mindfulness och New Age i det Moderna Västerländska Samhället
The purpose of the present study is to investigate mindfulness as a New Age phenomenon in the modern western society. Since a religious phenomenon does not exist in a vacuum, but is dependent on its historical and cultural context, my aim is to give a broad depiction of mindfulness and New Age in its wider context, the historical background and the societal implications of common values, themes and concepts that are frequent in the literature, how mindfulness is presented by the authors of popular literature and also how it is presented in science. In order to bring forward a deeper understanding of New Age and mindfulness? role in the modern western society, my intention is to see how the authors of mindfulness claim validity of their doctrines in the discourse. Mindfulness attracts a wide range of perpetrators and is used in many areas in the society today.
Engångshjältar - Hur myter och symboler konstruerar nationalism på Balkan
This thesis is about how nationalism is constructed from two competing groups, Kosovo Albanian and Serbs. Kosovo for Serbs is a deep symbolic value that continues to be a Serbian identification. This is one of the main reasons why no Serbian politician has the courage to give it up. On the other side of the coin we have the Kosovo Albanians that only settles for independence. To recognize the independence for Kosovo could jeopardize the security for the Serbian minority living in Kosovo.

Avbrottsfri Kraft med användning av ultrakondensatorer
The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.
Direktsamplande digital transciever
Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.

1553-Simulator. In-/uppspelning av databusstrafik med hjälp av FPGA
At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).
Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning
There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).
Power in the meeting between youth and police
Makt kan utspela sig på många olika sätt, i varje sammanhang inom varje rum finns någon form av makt. I min studie har jag valt att undersöka makten i mötet mellan ungdomar och polis, utifrån ungdomars berättelser. Ungdomar är vår framtid, det är våra framtida ledare och politiker, det är de som kommer att ta över världen efter oss, därför är det viktigt att vi tar hand om våra ungdomar och att vi skapar en ljus framtid för dem. För att våra ungdomar ska bli välartade måste vi undersöka förhållanden som påverkar dem och deras utveckling av jaget. Därför har jag valt att undersöka makten i mötet mellan dem och polisen då jag anser att mötet påverkar dem och deras framtid.
Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
