Användning av datorns grafikkort för beräkningar med användning av OpenCL (Open Computing Language)
SAAB Security and defense solutions i Järfälla har ett system som används av militären för övervakning av flygplan. Systemet visar på en datorskärm en karta över Europa där flygplanen visas med markeringar från data som samlats in av radars. Då data samlas in med en låg frekvens visas ytterligare en markering som kallas målspår. Dessa målspår beräknas fram med tunga matematiska beräkningar och sköts av datorns processor.Det finns ett önskemål om att flytta dessa beräkningar till datorns Grafikkort med hjälp av OpenCL och därmed frigöra processorns resurser. OpenCL har implementerats med två olika Java bindings och prestandaskillnader mellan dessa samt de ursprungliga beräkningarna har undersökts.
Barnens Kostlåda : Ett pedagogiskt arbetsmaterial riktat till förskolebarn. Utvärderat ur barnets perspektiv.
The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..
Själv-optimerande dynamisk adaptiv struktur för WebGL-applikationer
Utvecklingen av datorer och deras förmåga ökar klyftan mellan datorer och skapar en stor
mångfald av hårdvarutillgänglighet. Kapaciteten som datorer besitter varierar kraftigt och
därmed även förmågan att hantera komplexa applikationer. Moderna applikationer erbju-der inställningar som användare kan anpassa för datorn, något som kräver att användaren
har tillräcklig kunskap för att förstå inställningarnas e ekt. Att välja ut de optimala in-ställningarna för datorn är en process som är både svår och tidskrävande. Detta arbete
granskar hur ett dynamiskt adaptivt system automatiskt kan anpassa inställningarna för
applikationen medan den kör, utan manuell extern inverkan.
Kvantfysiken och den nya myten? : En studie av Fritjof Capras och Danah Zohars böcker om kvantandlighet
This study is about quantum physics and the role it can play in a religious perspective. I intend to examine how moderna physics may be related and understood as New age and Myths. My material consists of two books in the new age genre: "The Tao of Physics" by Fritjof Capra and "The Quantum Self" by Danah Zohar. My first two question to these books are which 1) religious and 2) scientific content they have. My other questions are too 3) investigate and demonstrate how these books are new age and 4) to exanine how the books can function as myths and adopt mythical features.

Affärssystem som molntjänst - En studie om vilka för- och nackdelar företag upplever med affärssystem som molntjänst
Studien beskriver de för- och nackdelar som företag upplever med affärssystem som molntjänst. De avgränsningar som gjorts är dels att jag valt att endast använda tre företag, dels att jag haft som krav att endast använda företag som har ett heltäckande affärssystem som molntjänst. Jag har använt mig av en kvalitativ metod genom att göra en fallstudie där jag intervjuat fyra personer på tre olika företag. Syftet med intervjuerna var att få en god inblick i vad de tycker att affärssystem som molntjänst har för för- och nackdelar. Frågorna till intervjuerna har valts ut med underlag från den relaterade forskningen jag samlat in genom vetenskapliga tidsskriftsartiklar, böcker och populärvetenskapliga artiklar inom ämnet samt från föreläsningar som getts på det systemvetenskapliga programmet i Göteborg.Studiens slutresultat visar att respondenterna anser att fördelarna är betydligt fler än nackdelarna.
Förnuft till döds? Debatten om Georg Henrik von Wrights bok: Vetenskapen och förnuftet
This paper relates a debate on a book Vetenskapen och förnuftet (1986) written by the Scandinavian philosopher Georg Henrik von Wright (1916 - 2003). The book brings up fate of mankind, raising the question if human rational thinking and scientific achievements are threatening our very existence on earth. Shortly after the book was published, it was intensively debated in a leading Swedish newspaper Svenska Dagbladet. Some 20 leading politicians and scientists contributed with their criticism during spring 1987. The paper highlights this debate by writing reception history, describing how the book with its serious message was received by leading scientists of the time.
Time Machine Computing for Media Improvisation
C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.
Informationspark? Informationsstrukturerna hos bioteknikföretagen på Ideon
This thesis deals with information provision to the knowledge intense biotechnology businesses of Ideon Science Park in Lund, Sweden. Previous research concerning the information needs of Science Park companies has been conducted from the information provider s perspective. Instead, we apply a user perspective to find out what information needs these companies have, and how they prefer to acquire information. Central terms are: information, -needs, -acquisition, -consciousness, -strategy, small and medium sized enterprises, scientists and engineers, information (resources) management, networks, tacit knowledge, knowledge transfer and innovative milieux. The companies need scientific and business information; the latter is easily obtained within Ideon.

Svenska livsmedelsföretags val av etableringsstrategi : En studie om Abba Seafood och Oatly ABs etablering i Tyskland och Spanien
Since we all live in an increasingly globalized world where goods and money are transported more easily and with tougher competition, it is a natural step for Swedish companies to establish themselvs abroad in order to increase their gorwth rate and reach more customers. Today all of us belong to the same global network and the purpose of this thesis is to investigate which factors are important for companies when they choose to establish themselvs on a foreign market. The focus of the investigation has been the market of Germany and Spain, since both countries just like Sweden are members of the European Union, but still have quite different characteristics. We, the authors, have also been living in Spain and Germany during the time of investigation and writing. The companies we have chosen to look closer into are Abba Seafood, which now has merged with Procordia Food, and Oatly AB.
?En strid om ord? En diskursanalytisk undersökning av riksdagsdebatten om kristendomens ställning i Lgr62
This essay examines the 1962 Swedish parliamentary debate preluding the proposition to introduce a uniform compulsory education for all Swedish children. The proposition aimed at ending the previously heterogeneous educational system and replace it with a more equal and democratic system.A widespread debate ensued, regarding the status of Christian religious education (kristendomskunskap) and its new emphasis on scientific objectivity. This essay will examine the relative position of Christianity within the new uniform school system, as it was articulated by the members of the Swedish parliament. This analysis will be achieved through the use of a discourse analytical study of the parliamentary records, the recorded motions and bills. From these records a substantial disparity in the parliamential members articulation of the concept of Christianity can be ascertained, even within the discourse of an educational regime.

A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.
Avskogningen av Amazonas
Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.
