Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.
Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.
Och kvinna : en kritisk analys av den mediala diskursen kring kvinnliga politiker
The aim of this paper is to describe, visualise- and analyse media’s discursive representations of female politicians in Swedish printed media. The focus of the analysis is to show if, and how these images can be understood and interpreted in terms of a socially constructed gender stereotyped suborder. The paper takes it's theoretical and methodological departure in the discourse analysis, which is combined with feminist political theory. Feminist political theory is concretised in the use of what Yvonne Hirdman calls the "gender system" which arranges the sexes into their respective genders and is based upon two rules/principles/logics: 1) the rule of distinctive separation, and 2) the male norm. Closely related to the aim of the paper lies also the critical theoretic assumption that people has to be aware of their own part in the production and reproduction of the discourse in order to change make a change.
Meningen med meningsförändrande innovation inom robotikbranschen : En explorativ fallstudie
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.
MAKT, EN FÖRUTSÄTTNING FÖR HJÄLP? : prykiatrihandläggares maktposition gentemot klienten
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.
Triac Driver Platform
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..

The theoretical framework drawn upon is post modernistic theory, social constructivism and intersectional theory.
Demokrati ur politikers och ungdomars perspektiv : - En diskursanalytisk studie om demokratiska förutsättningar i Norrköpings kommun
The democratic conditions in national states have change radically at the same time as the society has changed. Because of social and economic globalization processes, the states and government has lost power for the benefit of transnational and global institutions. That affects the democracy since the nation state earlier defined the domain of citizenship. At the same time, citizens? confidence towards political parties and politicians has gone down.
Skådespelerskor i politiken : En innehållsanalys om mediers gestaltningar av kvinnliga och manliga politiker
As a starting point the society is more enlightened and has gained a greater awareness about the gender power structures and its different forms. Present research shows the continuous development into other shapes and comes into different expressions that might be unrecognised. In order to gain knowledge about the present structure of the gender power structure system, the aim of this study was to investigate framing of female and male politicians in media. The main question asked was: ?are there framing differences in the portraits of the male and female politicians?? In order to achieve results articles in the biggest Swedish daily newspaper were examined.
Konst på internet idag : En retorikanalys av konstverksamma organisationers självpresentationer
This is a qualitative study about Art transformation and commodification in the digital age. The study applies a rhetoric analysis with the aim to understand how art sellers, gallery owners and entrepreneurs take part in this transformation process through their websites? presentation texts ?about us?. The analysis is related to communication theories but it is also inspired by other theories such as Gramsci?s hegemony theory and Bourdieu?s cultural critical theory.

Metoder för kartläggning och analys av nätförluster i lågspänningsnät
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.
System, stabilitet och makt - informationsdiskursen i Organizing Knowledge
TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.
Sveriges och Europeiska Unionens biståndspolitik : En jämförande idéanalys ur ett postkolonialt perspektiv
The main aim of this study is to examine the development policies of Sweden and the European Union from a postcolonial perspective. Sweden and the European Union are increasingly coming to be viewed as normative powers rather than military powers. So how does the colonial past of the western societies affect the policies of today? Are there any signs of the power structures of the past, and if so, how are these power structures manifested in the development policies of today? Since both Sweden and the European Union have come to be viewed as normative powers they are compared with each other to highlight their similarities and differences. The results of the study shows that both Sweden and the European Union can be seen as carriers of western values and interests.
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.
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.
