At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of image coding must be used. Because of this the greater part of this thesis is concerned with image coding.

This thesis processes the work of developing CPU code and GPU code for Thomas Kaijsers algorithm for calculating the kantorovich distance and the performance between the two is compared. Initially there is a rundown of the algorithm which calculates the kantorovich distance between two images. Thereafter we go through the CPU implementation followed by GPGPU written in CUDA. Then the results are presented. Lastly, an analysis about the results and a discussion with possible improvements is presented for possible future applications..

Den här C-uppsatsen utforskar möjligheterna att utforma applikationer till interaktiva plattformar som lär barn att lösa abstrakta problem och samtidigt är användbara för lärare i skolmiljö. Uppsatsen presenterar olika teorier och använder sedan det insamlade materialet som utgångspunkt för att testa om och hur dessa teorier kan tillämpas i ett specifikt fall. Resultatet sammanställs i form av en prototyp som testas på en klass förstaårselever i Stockholm..

My curiosity concerning what pupils read and write during leisure time led me to gather information using a quantative method. The study's aim is to investigate which reading and writing habits they have during their time outside school. A comparison was done of pupils at school year level 3 and level 4 in two different schools with the intention of investigating the influence of social background on reading and writing habits. 137 pupils filled in survey forms and thereafter the MYSTAT statistic program was used to process the information. The results point towards that the pupils read story books both more often and for a longer time than any other type of literature and that they read them often or very seldom.

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Galna Glassen is a company that has a unique way of selling ice cream in Sweden. The idea is for the costumer to be able to compose their own favorite ice cream, partly by choosing the flavor of ice cream but also by picking the ingredients. The ingredients that can be chosen from are around twenty and can be everything from cookies to candy to berries. When the costumer has chosen their ice cream and ingredients they are mixed together on a cooled granite board.The company was very successful when it was founded in the summer of 2011 and decided to expand to other cities in Sweden. They also wanted to explore the profitability of a mobile sales unit that is intended for festivals and events.The thesis is meant to develop Galna Glassen?s mobile sales unit.

Ericsson Mobile Communications AB (ECS) i Kumla producerar mobiltelefoner, främst digitala mobiltelefoner. Produktionsenheten ytmontage producerar idag kretskort baserade på prognos erhållen ifrån slutmontage som slutmonterar den färdiga telefonen. Problem har dock uppstått efter införandet av Build To Order (BTO), detta innebär en utvidgning av synen på att producera en telefon mot kundorder. Prognosen tar dock inte hänsyn till slumpmässiga fluktuationer, vilket innebär ojämn produktionstakt samt ökad belastning på personalen inom ytmontage. Problemen förvärras ytterligare genom att vissa kretskort ska produceras hos legoleverantörer.

I detta arbete har vi studerat tjänsten SMS-betalning. Vi har fokuserat på att utvärdera och beskriva tjänstens användningsområde samt dess styrkor och svagheter. Utifrån företaget Mobill, vars affärsidé är att utveckla en betalningstjänst via SMS har vi fått en bild av hur ett företag kan satsa på denna teknik. I en studie med konsumenterna har vi visat den generella bilden av inställningen till betalningstjänsten, detta för att vidare kunna utvärdera betalningssystemet. Dessa studier har båda en kvalitativ karaktär.

This study is aimed to increase the knowledge about the Swedish immigration authorities? assessment of the asylum applications based on particularly distressing circumstances, submitted by disabled undocumented migrants. Making an attempt to explain the reasons of asylum-seekers? health deterioration during the asylum process, this study determines the factors in migration authorities proceedings affecting such deterioration. Documents in five personal files concerning six disabled asylum-seekers, whose applications were declined, were studied by applying two observational methods: content analysis of the documents in the personal files and non-participant observations made during receptions of undocumented migrants at the Swedish Asylum Committee.

Ibyggbranschen i Sverige idag strävas det efter att fortsätta utvecklingen av eneffektivisering gällande miljö, kvalitet och styrning.Samhället och byggbranchen har utvecklats och digitaliserats enormt de senasteåren, dock har vissa mindre delområden avstannat och det är bland annatdigitala metoder för arbetsordrar och registrering bland hantverkare.  Studien som är gjord syftar därför till att undersöka ifall det går atteffektivisera och digitalisera metoder gällande arbetsordrar och registrering.Uppsatsen syftar till att undersöka ifall det går att effektivisera styrningen,miljöpåverkan, kvaliteten och ekonomiska delar bland byggföretag med hjälp aven mobil applikationslösning.I studien har jag valt att använda mig utav teori gällande miljö, kvalitet,styrning och finansiering där jag fördjupat mig i delar som är påverkningsbarmed hjälp av ett digitalt verktyg i form av en mobil applikation och dessfunktioner.För ett införande av applikationslösningen krävs det en invänjning och enmotivation ifrån hantverkarna eftersom att det innebär en stor förändringjämfört med den manuella metoden som använts under en längre tidsperiod. Detframgår att arbetsbelastningen för vissa delar i arbetet kan minska blandtjänstemännen vid  ett fullständigtinförande av den mobila portalen eftersom att vissa led försvinner när detgäller bland annat arbetsordrar och registrering. Jag kan konstatera att enförbättrad och förenklad version av applikationslösningen krävs för att få ettfullständigt införande bland hantverkarna..

The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..

Over the last couple of years, growers, researchers, advisors and plant protection companies have noticed increasing problems with tortricids in Swedish apple orchards. Since the insecticide Gusathion (azinphosmethyl) has been banned (end of 2008; KemI 2008), a further increase of tortricid populations can be expected. In order to get a picture of species composition and population densities among the tortricids, an inventory of seven species, Adoxophyes orana, Archips podana, Archips rosana, Cydia pomonella, Hedya nubiferana, Pandemis heparana and Spilonota ocellana was made in 11 orchards in southern Sweden (Skåne) in 2008. Population densities were estimated by bud sampling (April 20-25), pheromone trapping (May 5-September 22) and assessment of fruit damage (September 9-12). In all orchards A.
