In this final thesis a rough description of aluminium extrusion is made, the importance of temperature of both the raw material and the extruded profile for a good profile quality. The difficulty in controlling these temperatures are discussed and attempts to increase the control are described. The attempts are basically made by controlling the furnace that is heating the raw material. This is done in a manner that the raw material reaches its final temperature shortly before it is extruded. An IR-camera at the press can be used for profile temperature measurements.

The purpose of this essay is to analyse and understand how students, as consumers, choose brands from the aspects of the concept of CSR, the economic, social and environmental. The essay is based on a qualitative method with three focus groups, with five respondents in each of them. The respondents are all studying at Kalmar University and they have all studied some kind of economic-course. We have used a lot of different sources for our theory chapter, this because of the fact that we wanted to have different angles, so that we would be able to cover all of the questions we wanted to discuss in the focus groups. In our two final chapters we discuss the issues similar to the theory section and we highlight our own thoughts.

My thesis is an attempt to clarify the purpose and workings of art in relation to the artist, his/her fellows and society. Can art be considered as a uniting force? If so, where does its unifying quality lie? How does art connect with the individual, the community and society? My interpretation of the political climate regarding the arts has resulted in an exploration of the question: What role does art have in society today?The artistic ego as an altruism ? within the title of this thesis lies an absolute paradox ? a paradox that through this paper is tested, reviewed and demonstrated as a way of describing art and its workings. The thesis is problematized and studied from several angles: Through the inner artistic process, both reflective and empirical, and through philosophical studies..

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

The demand of nature tourism is increasing and new ways to satisfy tourists are necessary.The goal with this report was to answer that demand by exploring the possibilities for backcountry skiing north of Torneträsk. This area was chosen because it is unexplored. This hasbeen succeeded by an extensive fieldwork. Aspects like topography, routes, slope angles andgeological places of interests where recorded. The results has shown that back country skiingis well suited for this area and poses no negative impact on the natural habitat.

Background: Every patient and each situation is unique. Therefore the nurse has to act in a flexible intervention and still keep an ethical perspective. Aim: The aim of this studie was to illuminate nurses? different aspects of decision making in emergency situations. Method: The result is based on nine scientific articles.

The objective with this project was to design a new lifting aid connected to toilet chair.A questionnaire distributed at three homes for aged people indicated that there was an interest in a mechatronic lifting device.Since existing products have limited tilting functionality, the new design was chosen to introduce lifting by motorised tilting of the sitting platform. The mechanical construction was analyzed based on a maximum load caused by a person with weight 160 kg. Two linear actuators were used to control the tilting/lifting of the sit ?place, making standing-up easer.Finally, 28 persons tested the new lifting device and gave their impressions. Many appreciated the safe, stable lifting speed.

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context. I have explored different light sources and compared them to each other and given a short description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms. I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.

The purpose of this study is to investigate the children?s mathematics learning through play. The questions to be answered are: how can teachers facilitate children?s mathematics learning through play? How can play affect children?s math learning? Are the children aware of the role of play in their mathematics learning?My method is based on interviews and observations. My informants are three teachers who work in two different preschools.

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.

This paper examines how and if the understanding of wedding photography has changed during the shift of technology - from analog to digital photography. It examines if the changed conditions due to the shift of technology have changed the habits and conditions for the photographers working with wedding photography. It furthermore examines what impact these habits and conditions have had on the pictures of weddings. The investigation is based on interviews of six photographers that have worked professionally before and after the shift of technology, as well as of pictures by the photographers taken before and after the shift of technology.Use of time and space has changed due to the shift of technology. The change has also had an influence on hierarchy among the photographers.
