The central theoretical ideas for this study are representation, stereotypes and racialization.

Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Alternativa metoder för att kontrollera ett användargränsnitt i en browser för teknisk dokumentation

When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.

An analysis is made to compare the present weapons and fire power of the reconnaissance squad with an extended weapon alternative. The analysis focuses on the abilities effect, protection and movement in different situations typical of a reconnaissance squad.The facts that are presented in this paper are mostly founded on the new field manual FältarbR Dyktjänst 2007, which regulates much of the reconnaissance activities. The aim of this paper is the making of a contribution in the developing progress of the new field manual and the reconnaissance squads in Swedish engineer battalions.The result of the analysis shows that the extended weapon alternative would be an asset..

Nytt spritsrör på TwinRoll typ TRPE : Undersökning av kostnad på spritsrör

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Transporter på väg - En studie över Sveriges lastbilscentralers metoder för att möta ökande drivmedelspriser

Background and problem: In the last few years the threat against the environment and especially the emissions of carbon dioxide has become increasingly debated. The government have set up a goal to lower the emissions of carbon dioxide with 40 percent until 2020 compared to the level in 1990. The emissions in the transportation sector have, in contrast to the total emissions, increased since 1990 and will continue to increase unless powerful control measures are implemented. The lorry centres have to use strategies to answer to these external threats which lead us to the two questions of this thesis: - What methods do the lorry centres use actively and which do they consider as the most important methods for fuel saving? - Are there any differences which methods small, medium and large centres considers as important? Purpose: The main purpose of this thesis is to examine which methods lorry centres use actively and which they consider as important for fuel saving.

Tanter

AbstractWhen I, at the age of 20, started working in home care service, I had an idea of what it means to age, a view witch I quickly realized was not true at all. The essay begins with a search for the images of aging you come in contact with, when you do not have a deeper interest in the matter.I take a closer look at how aging is described and how the concepts of aging and dignity are often interconnected, and debate about which images of aging that is outdated and where from they originated.I also show that that image is in for a change, much is happening right now, and there are many like me, who want to change and broaden the view of what aging can mean.Finally I describe my sculptures ?Beatrice? and ?Rosmari?, and reflect on how they relate to the image of what old age looks like.As a sculptor, I want to create an alternative to a widespread image of old people as a problem or idealization of the olf lady as a kind, cute and cookiebaking creature, as well as an alternative to the traditional sculpture tradition, that often show men in positions of power, and sweet passive women/girls.I tell of the strong, stubborn, eccentric and absolutely ordinary lady.

En vision om Enhetsskolans återkomst

I have taught pupils in several schools in eighth and ninth grade in ?weak? groups in mathematics. Most of them seemed to possess potential, but lacked motivation. Even though I tried several pedagogical methods, these approaches failed to engage the students. This prompted thoughts that this may reflect a broader structural problem about the organisation of education in Sweden.

Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.
