Det här arbetet är en utvärdering om huruvida det finns problem som kan få en prestandavinst då man använder en Field-Programmable Gate Array (FPGA) som hjälpprocessor till en mikroprocessor i jämförelse men att enbart använda en mikro-processor. För att avgöra detta implementerades algoritmen gaussfiltrering dels på en mikroprocessor med språket C och dels för en FPGA med hårdvarubeskrivningsspråket Very-High-Speed Integrated Circuits Hardware Description Language (VHDL). Simuleringar gjordes för dessa två implementationer och resultatet visade att det var möjligt att få en prestandaökning på 25 gånger för denna speciella algoritm..

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

User friendly and usable are two words that are often mentioned in the context of marketing new products. By doing so it adds an extra sense of quality to the product. The meaning of these words is therefore something that every product wants. But what is it that makes a product usable and user friendly? What methodology exists formaking sure that a product is usable? Does it exist applicable processes to ensure user centered development? These questions together with a practical example are parts of what will be addressed in this report.The thesis was carried out for C2 Management, a company that works with supporting other companies in their work with quality and constant improvements.

This study was performed in an afforestation experiment established 1982 on an abandoned peat harvesting area, Flakmossen, in the province of Värmland, SW Sweden. The experimen-tal design include planting with Scots pine (Pinus sylvestris), in combination with various drainage intensities (20, 30, and 40 m between ditches), and fertilizer doses 0, 100, and 200 g PK per seedling applied at the date of planting. The aim of this study was to achieve more knowledge about the conditions on afforestation of peat harvesting areas, especially regarding drainage intensity and fertilization requirements, by means of determining the stand growth and yield in the Flakmossen trial. The forest growth did not differ significantly between the drainage intensities tested when the same amount of phosphor and potassium fertilizer was added. Thus, shorter distances between ditches than 40 m can not be recommended. When no fertilization was carried out seedling survival was very low, and the growth of sur-vived seedlings was poor. The largest diameter and height growth were observed in the areas where the highest dose of phosphorus and potassium (200g/seedling) was given.

This paper deals with the difficulties of applying user-centered design practices as an independent developer, based on the visualization of a game concept in the form of a prototype. The aim is to evaluate the usability of user-centered design practices, specifically in the field of games development. Throughout this paper, I will give an account of the methods used for testing, as well as a review of previous research done in this field of study. Finally, I will end with a discussion regarding the pros and cons of user-centered design, as well as some thoughts about its importance in similar projects..

Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.

The primary aim of this essay is to analyse, contextualise and problematise the scientific and technological goals of android science. The starting point of this investigation is the history of automata and man?s attempts to recreate himself by technological means. Drawing on the no-tion of boundary work this essay also analyses the efforts of the proponents of android science to establish and demarcate a new interdisciplinary field. A secondary aim of the essay is to evaluate the scientific support for the uncanny valley hypothesis and to investigate how this hypothesis contributes to android science.

This study investigates verbal and visuospatial memory strategies used by individuals with perceptual or cognitive disabilities. The groups concentrated on in this study are deaf individuals who are native sign language users and individuals with dyslexia. The study comprises an experiment and an in-depth study in which a pre-test and a questionnaire were used. Nine deaf signers, two persons with dyslexia and 12 persons without any perceptual or cognitive constraints participated. Of these 23 persons, seven were selected to take part in the in-depth study.

The structural rationalization of rural firms in Sweden has led to many new creative ways of developing companies. The agriculture sector is characterized by the need of capital in form of buildings, labor and inventory. The rationalization process has led to free capacity in rural firms when new technology make buildings and inventory not longer necessary for the production process. To get a better cost coverage this free capacity can be used to start-up new business areas that help the rural firm to growth.The study aims to identify factors that motives entrepreneurs in rural firms to develop new business areas. The purpose is also to analyze driving forces that lies behind development of rural firms and the forces that support or not support development in rural firms.The study is built upon five cases that all can be categorized as firms with different size and orientation.

The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.

The purpose of this essay is to show how ESN, IKEA and the Ministry for Foreign Affairs (UD) mediated swedishness. This will be done by illustrate and analyse the methods the research fields use to create and spread pictures and message about Sweden, Swedes and Swedish cultures. The essay use the method of represented informants and show three field where the meeting between people and cultures is conspicuously. Hopefully, this essay can be seen as a contribution to the research of identity (identity research). I have chosen to focus on three fields of research, which do not belong to the classic field of research to show how swedishness is mediated..
