En välfärdsstat i förändring. Friskolans intåg.

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.

Analys av spänningsstabilitetsberäkningar i det svenska elsystemet

Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.

Innovativt Drivpaket för Rullstol

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi

Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.

Drivaxeltrycksreglering hos tunga fordon : För en ökad framkomlighet vid vinterförhållanden

Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

Den fördelade makten i vardagsrummet: : En kritisk diskursanalys av PR-konsulters tal om sociala medier som kommunikationskanal.

The purpose of this study was set against the background that social media today are used as an platform for companies to communicate with their customers, as well as communicate their brand. Therefore it was interesting to examine this phenomenenon through a critical point of view and try to put light on the different forms of power that is produced on this arena.The overall aim of this study was to examine how PR-consultants talk about social media as a communication channel. The empirical data consisted of five interviews with PR-consultants on five different PR-agencies. The theoretical framework was based on a social constructional perspective and Foucault?s theory of power.

Business intelligence : Framgångsfaktorer vid användningen av ett BI system

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

Beräkning av vågkrafter på en gravitationsplattform

This essay is about North Korea, Kim Jong Il and how the future looks for the states political system. The purpose is to explain how Kim Jong Il and the North Korean regim rules the state and with help of Machiavellis theory about the Prince, tell about the states future. The essayinvestigates how well Kim Jong Il and the North Korean regime are keeping their power overthe state and if their possibilities to continue in the same way are good or bad. The essayinvestigates North Koreas possibilities for further reign through Niccolo Machiavellis theory.The argument is that the North Korean state and Kim Jong Il have few or noneconditions to continue with the same political system that the state in this time have.The result shows that, through a Machiavellian perspective, Kim Jong Il and the North Korean regime have bad conditions to continue ruling the state in same way as now. The investigation, unfortunately, do not show when and how North Korea will be exposed to a government switch , but the result points to a change..

Åtråvärda objekt : En gestaltning av troféns materialitet

This thesis revolves around my work Desirable Objects, an installation in glass and other materials, which deals with objectification based on female and animal trophies. The topics included are those that have been crucial to my working process; craft, post-colonial studies and European hierarchical dualism, where woman and nature are seen as connected, but inferior. My motivation has been to get a better understanding of underlying power structures, and put this knowledge in relation to my own work. This process has led me to make a full body casting of my own body as a method of self-exploitation, in an attempt to expose myself to a similar power perspective. By making the dualistic connection between woman and nature, I am commenting a phenomenon that in my view has resulted in a similar exploitation of both..

Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation

The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.

Visuell presentation i slöjd : Positivt med power point?

Detta arbete undersöker problematiken i att visuellt framföra och presentera ett arbetsområde i ämnet träslöjd. Uppsatsen handlar även om och hur slöjdlärare kan undvika onödig stress. Syftet med uppsatsen är att undersöka hur man i träslöjd kan utvidga sättet att presentera uppgifter för eleverna på ett inspirerande, innehållsrikt och konkret sätt. Genom att bedriva en praktisk visuell presentation i form av Power Point har jag fått en uppfattning om ett alternativ till den traditionella undervisningsformen i träslöjd. En utvärdering gjordes med eleverna efter Power Point presentationen och den visade bland annat att eleverna i år 4 fick mer utbyte av uppgiften jämfört med år 5-6.

Tysta flickor och högljudda pojkar : Observation om pojkars och flickors könsroller med utgångspunkt från likabehandlingsplanen

This study is about gender in classroom situations. The purpose is to examine if gender still exist although the government has educated gender teachers. I have been observing students during lessons and taken notes on teacher´s comments, which analysed. I have come to the conclusion that the students are awase of the power roles conserning gender and gender. In this classroom the heteronormativity still is a common phenomenon.

Övervakningssystem för båtelektronik

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Dags att förändra den svenska utnämningspolitiken! En idéanalys

This paper discuss the possibilities to improve the Swedish political nomination system. It brings up some of the values and norms that can be used to change the existing system. Values as openness, the demand of responsibility and also if there is values from the American spoils system that can be used in the Swedish system. A minor purpose is to discuss the part of the parliament within the nomination process. To investigate this I have some theoretical starting points and a self constructed analysis tool.
