New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

The purpose of this thesis is to identify power structures and instruments of power within the Jehovah?s witnesses and investigate how they affect the baptized youths baptized within the organization. The material consists of qualitative in-depth interviews and is analyzed with Foucault's theories of power. The results show that the participants have a very strict relationship to the rules of the congregation and also that they take great care in observing these rules carefully. It becomes evident that young members are exposed to disciplinary measures from the organization.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Syftet med den här uppsatsen är att få en inblick i statens föreställning om psykiskt funktionshinder i historien genom att undersöka två statliga utredningar från 1940- och 2000-talet. De två utredningar heter Betänkande om sinnesslövården (1949:11) och Ambition och ansvar (2006:100). Med hjälp av Foucaults maktteorier om disciplin och normaliserig ska jag analysera utredningarna för att ta reda på statens föreställningar.  För att specificera föreställningarna har jag analyserat temavis. De teman jag har valt är begreppsanvändning, vården och utbildning. Genom en textanalys av utredningarna har min undersökning visat på att föreställningen om psykiskt funktionshinder har förändrats enormt genom historisk tid.

This thesis examines the power of developing countries within the World Trade Organization (WTO). The research question is if there is a change in the power relations between developing countries and developed countries from the establishment of the WTO in 1995 and until mid 2006, and if so, why this change is taking place? The thesis has its theoretical starting-point within regime theory and views it from a critical theoretical perspective. A multidimensional why of dealing with the concept of power is being used to answer if there is a change in the power relations? The conclusion is that there is a small change in the power relations and that the developing countries are gaining more, but limited power.

The interest for wind power has increased in Sweden. Northern Sweden is especially interesting due to that a new wind resource map shows that there are areas in northern Sweden that have more potential for wind power than what have been known before. Therefore E.ON Vind is interested in finding out if, and where, there are suitable places for establishment of wind power in northern Sweden. The purpose of this master thesis is therefore to perform an inventory of northern Sweden for suitable places for wind power. The master thesis is performed at E.ON Vinds office at Vasagatan in Stockholm.

There are very few studies that have taken the matter of teacher?s leadership in disciplinary actions into research. That is why the purpose of this essay has been to investigate the relationship of how students think their teachers appear in questions of discipline. The study has been narrowed down to gather and analyze the experiences that students have about teachers, and how teachers uphold and set themselves to ground rules in the classroom. The study has shown how the students interpret teacher?s act of following up consequences of classroom rules.

The purpose of this study was to increase the level of knowledge in the field of Environmental Impact Assessment (EIA) for wind power. The study includes six wind power farms in the County of Västerbotten in northern Sweden. The main questions were: What are the real dimensions of roadways and land claims for both roads and wind power turbines? How do those dimensions correlate with the dimensions stated in the EIA? Are there any differences in values of the dimensions between the wind power farms that are included in this study? The width of the roadways and the land claims for both roads and wind turbines in wind power farms were examined on site. The results from the examinations were compared with the dimensions available in the EIA for each wind power farm.

AbstractAuthor: Ellinor Carlsson and Renate HöjdTitle: "When you can make a difference and when you can´t" the power relation between psychiatricdisability social worker and client [translated title]Supervisor: Eva SkogmanAssessor: Norma MontesinoOne branch of the social works field of research is the relation between social worker andclient. Research has shown that the power and inequality in the relation between helper andperson being helped is needed for the helper to provide help. Power is often mentioned undernegative circumstances such as social workers abuse of their power position, violating theperson being helped. However, Michel Foucault suggests that power is something neutral thatexists in every social interaction. The negative aspects of power are effects of the parties notreaching agreement.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

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.

Violence against teachers in Swedish schools, according to recent reports has increased and there have been many studies to investigate the situation for teachers. The surveys show that teachers are especially vulnerable to students. This study aims to examine the relationship between a number of teachers and their students to study the power relations that exist in the classroom. This is to see what violence is an expression of and also how violence is perceived by the teachers. The issues that are central in this study are:What is the importance of dialogue in the relationship between these teachers and their students?Is there power relations between teachers and their students?What is the violence against teachers and expression of?Is there any connection between dialogue, power relations and violence?The theories of the materials in this study was analyzed using power relations theories of the historian of ideas Michel Foucault and Philosophy Doctor Anders Persson, who to some extent has his theoretical basis in Foucault?s power relations.
