The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept prototype..

Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

In the centre of Bromma, east of Brommaplan is the part of Bromma named Riksby. Riksby was built in the early 1940:s as a part of the westward expansion of Stockholm. Other places that were built at the same time was for ex. Stora Mossen and Abrahamsberg. This work is about the outdoor environment of the housing co-operative of Brickbandet.

SNA Europe?s handsaw concept is called ?Bahco Handsaw System? and is constituted by a saw handle with the possibility to switch between different saw blades. The sales of ?Bahco Handsaw System? products have not achieved the desired results probably due to the high price. Developing a more cost efficient handle, enabling a lower consumer price of the product, is assumed to increase the sales volume.

This is a project with the main purpose to create a visual identity and platform for the release of the new started record label Human vs Environment, by finding a form and logotype for the homepage and packaging of the first vinyl ep record by the artist Mr Kaizen. This has also been an exploratory work with the target to get a broader competence in the field of visual communication and increase my understanding of the designs communicative aspects of running a design project with an external partner from concept to finished product..

In this essay I have described ecocriticism as a theory with several different subfields that are inspired by a cross-disciplinary approach, such as green culture studies, ecofeminism, and postcolonial ecocriticism. After a short summary of the background of ecocritical studies I analyze the various subfields, take a closer look at their contents and present various examples of ecocritical thinking. A presentation of the commonly used concepts within the discipline and some reflections on these is followed by my final discussion, where I state that even though ecocriticism is a relatively new theory and the concept doesn?t have a clear definition as yet, it is in my view a useful tool for analysis and can with time make valuable contributions to literary studies, not least by introducing a number of new perspectives..

Volvo Construction Equipment is a world leading company in construction machinery. Tomaintain the best products, development is prioritized. The master thesis regards sound reductionof the hydraulic system on a wheel loader. The background to the master thesis is asimulation made on the hydraulic system, performed autumn 2005. The result of the simulationshows that the energy of the pressure ripple is reduced when the paralleled hydraulicpumps are phase shifted and reduces each others pump pulsations.

This paper examines the concept of environmental scarcity and the risk of conflict, in particular agriculturalscarcity and the risk of conflict. This paper compares the neighbouring countries Angola and Namibia, andinvestigates why Angola has had a conflict and why Namibia has had peace. This paper investigates if the conflict inAngola is caused by agricultural scarcity and if this is the explanation for the lasting Peace in Namibia..

The development of higher education in Sweden poses new demands on higher education libraries. One way of meeting these demands has been to develop Learning Resource Centres (LRC), a concept that is relatively new in Sweden.The aim of this Master's thesis is to identify how the LRC-concept has been designed and integrated in three Swedish higher education institutions: Stockholms universitet, Lärarhögskolan i Stockholm and Göteborgs universitet. The thesis also aims at investigating what the Learning Resource Centres mean to the seats of learning, and in turn, the views of concerned parties in relation to the integration.The method used for the study is qualitative and based on interviews conducted with Learning Resource Centre staff, academic staff and principles or deans. In addition to this, strategic documents from the examined seats of learning are studied.Even though most Swedish Learning Resource Centres have used British Sheffield Hallam University's Adsetts Centre as their model, our study shows that the Swedish Learning Resource Centres of today have developed in various ways, due to local conditions; therefore, there is no definitive model for Swedish LRCs.In our opinion, one of the most important characteristics of a LRC should be its integration in the academic life of its university. There does not seem to be a "recipe" of how to conduct this integration.

It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..

Through participant observation in a local promoter group of hardcore punk shows inGothenburg and qualitative interviews with its members I have investigated links between taste in music, values and social structures in the hardcore punk scene. The theoretical framework of this essay is built upon the concept of subcultural capital, which is adapted from Pierre Bourdieu and developed by Sarah Thornton and Keith Kahn-Harris. The result shows how members among the hardcore punk scene create and preserve distinction towards others, while the distinction becomes important benchmarks for including and excluding practices in the scene..

This thesis work is a 30hp D-level assignment in design as a co-operation between MälardalenUniversity and Scania CV AB in Södertälje. The purpose was to develope a close fitted catwalk.The market has seen an increasing value for these types of applications and have the ambition to keep up with the rest of the competitors. The catwalks of todays standards shall be estetical attractive, have a non slippery surface and be costefficient.While working with this project I have spent a lot of time with the concept proposals and with the evaluation of the concepts, resulting in a final CAD model and a approximation of the cost estimate. The new catwalk fulfils all the new recommendations and rules as sharp edges, ADR, the height of the stepup and a non slippery surface with built in drainage..

The newspaper industry changes with the society. New trends and developments affect how layout and design are perceived. Therefore it is important for the survival of a news­paper to catch up with trends and retain contemporaneity. This demands that a daily paper frequently updates its appearance and sometimes even redesign the whole newspaper. Folkbladet, a newspaper in Norrköping, is currently in need of a new layout. The employees often deviate from the graphic guidelines that exist at the company today, due to that it doesn?t feel contemporary, but also because they don?t appreciate the appearance as it is today. This thesis is based on a study of the layout of Folkbladet and analyse: which tools can be used to create a distinct identity regarding layout, which tools you can use to create a clear structure and readability in a newspaper, and how Folkbladet can make use of these tools. To find out about the company?s situation today and their identity, interviews have been made with employees.

This thesis is a study of how Norse religion and early Christianization is presented in three Swedish museum contexts. Empirical studies of the exhibitions relating to religion have been conducted at The Historical Museum in Stockholm, The Museum of Gotland and Östergötlands Museum and interviews with the museum staff compliment the empirical data. The concept of religion has been problematized to facilitate the analysis. The result of the study is that there are tendencies to make a hierarchical order between the different religions and that Christianity is an organized religion while the Norse religion is semi-organized..
