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.

Dialog, maktrelationer och våld : En kvalitativ studie om maktrelationer i klassrummet och våld som uttryck för motstånd

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.

Religion och vetenskap i läromedelsböcker : En studie av vilka bilder av religion och vetenskap som förmedlas i läromedelsböcker i religionskunskap för gymnasieskolan

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.

Upphovsrättens balans: en idéanalys av bibliotekssfärens remissvar på Ds 2003:35.

The aim of the study is to examine ideas surrounding copyright law and related rights appearing in the referral statements that the participants of the library sphere gave to the department writ Ds 2003:35. These ideas reflect the positions the library sphere take regarding issues surrounding the copyright law and related rights. The department writ was preceded by a directive from the European Union; Directive 2001/29/EC of the European parliament and of the council of 22 may 2001 on the harmonization of certain aspects of copyright and related rights in the information society. The writ Ds 2003:35 was later followed by a proposition from the government which was co-herent with the preceding writ. The empirical material has been analyzed with a starting point in the polarizations, artist/audience, private/public and original/copy, presented in PhD Martin Fredriksson?s book Skapandets rätt.

Republicans in the White House - Hard times for Soft Power? En teoriprövande studie om skillnaderna i soft power mellan demokratiska och republikanska administrationer

According to many scholars America's soft power is in decline, a power resource whose importance has been increasing in world politics. This makes it interesting to examine if there is a difference between how Democratic and Republican administrations wield their soft power.This thesis is a hypothesis-testing study and the purpose is to test the hypothesis that Democratic administrations, to a greater extent than Republican, can create, utilize and defend soft power. My thesis is based on Joseph Nye's theory of soft power and the focus of this study is the aspects of the foreign policy resources. In order to measure this concept I have made my own operationalization where five different indicators serve as my guidance. I use the method of least likely-cases to select and motivate the administrations being tested, which gives me a comparative study of the Democratic administrations of Lyndon Johnson and Bill Clinton and the Republican administration of George H.

Håller vindkraften vad den lovar?

The purpose of this study is to investigate how much of the estimated annual electric energy production from Swedish wind power that actually was produced, as well as the history of this agreement over time. The aim is to also examine if there are properties that have caused some group of wind power plants to produce more or less, compared to their estimated production. Operational data on wind turbines collected by the Swedish Energy Agency was analyzed. A survey was made among owners of wind power plants with a nominal power of at least 2 MW. Two different methods for normal year correction of production data were used and compared.

Dagens Nyheters tryckeri: En jämförande tvåfallsstudie av företaget och makten

This study is an institutional analysis of the firm both as it is theoretically conceptualized and how it takes shape and changes. The role of power relations between manage¬ment and employees is especially examined with the aim of evaluating pos¬sible connections between the firm as an institution and power relations within it. Based on a comparison of two cases (two selected periods of the same organization) it asks ?How closely does each case match the conceptual characteristics of the firm??; ?What are the power relations between management and employees in each case??; and finally ?What factors account for the resulting differences??. It is found that there is a negative correlation between employee power and proximity to the firm as a concept.

Ekonomiska innovationer i den gotländska vindkraftsindustrin

Currently there is a controversial debate about that we must reduce our impact on the global warming; therefore both the Government and the local authorities have invested heavily in developing renewable energy in Sweden. The major development on the wind power market can be seen as a result of both the technological development and also on the decision that the Government took in 1996, which opened up the wind power market for private parties.This paper has aimed to examine the types of financial innovations that have arisen from the investments and financing of wind power on Gotland, and what these innovations can contribute to the future development of wind power.The problems that this thesis is based on is; what kind of financial innovations have occurred within investment and financing of wind power? How can these innovations contribute to the continued development of wind power on Gotland? The conclusion of this study shows that respondents and participants have defined a number of financial innovations that have emerged. Where some of the innovations only can be seen as incremental since they are based on continuous improvements, while others can be seen as radical as they are completely new for the context in which they operate. The study has also shown that Gotland has a great potential to produce more renewable electricity, but the development is dependent on the new power lines being built, in order to export electricity to the mainland..

Modell och analysverktyg för beräkningav frekvensförlopp

The power system modelled in this thesis work has been developed for simulationwhen e.g. the production in some part of the power system is changed. The powersystem has been modelled according to the swing mass of the system, the frequencydependency of the load and the turbine governor. The model determines the systemfrequency, the period of regulation and the power exchange between the differentsubsystems in the Nordic synchronized system.In this model the system frequency is assumed to be the same in all different parts ofthe power system and the voltage conditions in the power system are neglected. Forthat reason power swings does not occur between different subsystems in the powersystem, which usually occur as a result of the swinging connection between thetransmissions line.

`Hard eller soft power´ - när det gäller att främja demokrati och mänskliga rättigheter?

The thesis investigates how two of the world?s most powerful international actors, the US and the EU want to promote democracy and human rights. The aim is to compare how the US and the EU work in order to support a democratic development in the world. In order to fulfill the purpose of the thesis a qualitative text analysis was used. Since the aim is to compare the US and the EU I believe this method is beneficial.

Vindkraft och landskap

The current debate about environment and climate change has contributed to more andmore investment in alternative energy sources such as wind, solar and biogas. The Swedish Parliament has set the target that wind power should supply 10 TWh in 2015.In Sweden, wind power establishment began in the early 1980s. Since then the development has gained a tremendous momentum. The purpose of this study was to find out what problems wind power brings and what power relations that exists in connection with wind power establishment and how the landscape is affected by windpower construction, focusing on some cases in Falkenberg and Varberg. This study shows that wind power establishment is a very complicated process.

Does nuclear power plants affect house prices? : a hedonic price model of Forsmark nuclear power plant

Nuclear power plants existences have been well debated since the 70s (Swedish radiation safety authority, 2014). Accidents, risk and presence connected to nuclear power plants have been part of many studies around the world. Recent studies have shown a connection between prices of houses and the distance and presence of nuclear power plant in a surronding area of the house. This paper uses Hedonic price modelling to investigate the willingness to pay for an increased distance to the Swedish nuclear power plant, Forsmark. For the dependent variable selling price was used and the independent variables were number of rooms, living area, other area, lot size, selling year, building year and distance to Forsmark.

Att genom fiktion skildra en verklighet : En kvalitativ studie i hur maktstruktrurer beskrivs i BBC:s tv-serie The Hour

The objective of this study was to investigate how power relationships between journalists and politicians were shown in the fictional BBC tv-series ?The Hour?. We wanted to investigate how these power structures is narrated by the producers of the series and what impact the narration could have to the audiance of the 21th century.We choose to analyse a total of 12 scenes from all of the six episodes, which are all set in Britain during the beginning of the Suez Canal crisis in the 1950?s, all seen from a BBC editorial point of view.In our analysis we chose to use two different kind of methods, the first one was a situation analysis and the second one a text analysis. The situation method was useful to get a perception of the relations between the participants .The text analysis we used to analyse what was said in the tv-series and to interpret underlying motives.The fictional form necessitated a personalization of power structures, in the sense that each and every power was represented by a single character; political power was for instance represented by the character of Angus McCain.
