AbstractThis work was assigned by a technological company that manufactures gas detectors in which the sensor signal is processed using digital filters. These filters have been developed by a consultancy firm which converted previously used analog filters to digital filters. The purpose of this work has been to analyse inadequate, and sometimes erroneous, documentation from the project in order to provide the company with know-how and tools for further improvement of their products. The work has been done using the simulation software COMSOL which was bought solely for the project. Analysis showed serious flaws as well as pure errors in the consultant?s documentation.

Music production software has a strong tradition of two-dimensional graphical user interface (GUI), in which the time line is represented as a flat composition either horizontally (from left to right) or vertically (from top to bottom). In my degree work titled Sequi, I approach music composition from a different angle. Instead of a two-dimensional time line with only two possibly ways of progression (forward or backward) I constructed a three-dimensional GUI with the maximum of four different ways of progression from any given point in a composition. The height axis is used to describe time-intervals (the time between downbeats) and the wide and depth axes are used to describe progression from one sound to another..

Syftet med detta examensarbete är att med avseende på Snow Softwares databas försöka att effektivisera samt omstrukturera de procedurer som hanterar deras regelverk. Den är ej inriktad på att utvärdera eller förändra de algoritmer som redan finns i Microsoft SQL Server.Ett flertal olika prototyper framställdes och utvärderades. Dessa var ej specifika för just denna databas och kan därför vara intressanta även i andra sammanhang. Den prototyp som visade sig vara mest effektiv implementerades så att den enkelt skulle kunna tas i bruk i det nuvarande systemet. Prototypen gav en ungefärlig förbättring i söktid på 18,8 %.

The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.

The aim of this study is to investigate English teachers? communication when teaching English in grade three in Swedish schools. The investigation seeks to find out what language is, and why it is, dominant and how the proportions in the teachers? uses of English and Swedish in time are distributed. The study also describes what attitudes teachers have to the English language and if, if so how, two categories of strategies, namely body language and code switching are used.The study was performed in two steps with different methods for collection of qualitative empirical data.

With recent technical development computer aided design and manufacturing has taken amore important role in the product life cycle. New business segments such as Product/ServiceSystems and remanufacturing is emerging. This development demands better control of theproduct data throughout the entire product life cycle. Computer aided design is widelyrecognized and used within the manufacturing industries and in recent years the importance ofDigital manufacturing has increased. One part of Digital manufacturing is paperlessproduction which involves all orders and working instruction shown for example on a screenrather than on a piece of paper.

The Gift 2.0 - A Museological Study of donations of Objects and its Underlying Motives, is a study in order to explain why people choose to donate items for museums, rather than any other alternative.The empirical study consists of qualitative, semi-structured research-interviews conducted with seven selected curators from various museums, with extensive experience of the subject acquisition. I have chosen to only examine Swedish cultural-historical museums. The hypothesis that I assumed was first and foremost that the heritage sphere is what Pierre Bourdieu calls a field. The reason that people would donate objects to museums, is that the donation itself brings cultural capital to the donor, from people with the same habitus. Since I felt that Bourdieus theory of field, capital and habitus could not explain all the reason why people donate items to museum, my second hypotheses was that certain objects are what Annette Weiner called inalienable possessions, objects that at any cost may not be sold or bartered away.

I detta arbete har vi undersökt vilka faktorer som är viktiga för ett lyckat införande av CASE verktyg i en organisation. I arbetet har vi utgått ifrån de faktorer som teorin förespråkat och jämfört dessa med den empiri som vi har undersökt. De faktorer som vi har funnit i litteraturen har vi delat in i grupperna organisatoriska faktorer, utvecklingsfaktorer och stödjande faktorer. Vi har funnit att hanteringen av dessa faktorer i många fall skiljer sig mellan teori och empiri. Utifrån undersökningen har vi dragit slutsatsen att utvecklingsfaktorer har varit den grupp av faktorer som har påverkat införande mest i de undersökta företagen..

A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

An automatic control system for calibration of pressure indicators has been constructed. This control system can be used as a complement to the calibration system located at AerotechTelub, division MainPartner, in Linköping. The calibration system used today contains some not wanted pressure changes, which is compensated by hand today. The new system presented in this report automates the calibrating process and simplifies the calibration. Suitable hardware as motor, controls card and so on have been found and software in the form of Visual Basic program has been developed.

The aim of this study was to investigate how individuals perceive the process of sexual/romantic attraction. A phenomenological approach was used, where the participants were asked to reflect as freely as possible upon a question formulated by the authors. 13 persons were selected through purposive sampling, eight men and five women, all between 20 and 30 years old were interviewed but only 8 were analyzed through phenomenological based software MCA-Minerva. The results showed that all participants talked about three steps; eye contact, closing the distance and conversation. In the latter step they differed regarding actions taken to attract.

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.
