Prestanda och precision pa? en enkortsdator i ett system med realtidskrav
The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

This study aims at using discourse analysis to analyze SFI students attitudes to religion and religiosity in an SFI-context. The questions are: How is the discourse constructed and maintained by religion and religiosity of SFI students in an SFI context? How do SFI participants experience that their religion has affected their time at SFI?Using a case study approach, interviews were conducted with a group of SFI students. The results show that the religious discourse in SFI is influenced by the SFI-context and affected based on the current education discourse that exists there. Furthermore, the discourse is designed and maintained by the participants private religious beliefs and the religion of the majority of the group, One canhere speak of a strong social unit forming a plausibility structure The power structure that emerges is that the majority has the power to define the significance of religion and place within the SFI context. In the SFI-context the participants view is that religion is something private that should not be expressed in the school environment.
Utveckling och implementering av ett audiopejlsystem baserat på tidsdifferensmätning
The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

The purpose of this bachelor's thesis is to examine how public libraries in Sweden handles their weeding procedures. A series of questions are asked: How does libraries in Sweden motivate weeding? What principles constitutes the procedure of weeding? Which aspects are given most importance when weeding is decided. How does views on weeding differ between libraries of different sizes? How does longer or shorter professional experience influence the view on weeding? The study was done through an online questionnaire which was sent to a number of staff members on different libraries via e-mail.
Jämförelse av programvaror för konstruktion i råa punktmoln
Laser scanning is a method of surveying that has evolved rapidly in recentyears. The technique is based on a laser scanner set up, which can document a structureusing pulsed laser beams. Each time the laser hits a surface it is partly reflectedback to the scanner that stores the point. By using strategically placed targets, storedpoints from different scans can be merged into a point cloud. A point cloud is avisualization of the scanned object with a very high accuracy.
Finansiell psykologi : En empirisk studie av olika faktorers påverkan inom finansbranschen
Investors have been shown to be driven by emotional and psychological factors. This contradicts classical financial theories, for example the Efficient Market hypothesis which states that all investors act rationally. Behavioural Finance is an area of study which describes various psychological factors which may result in irrational investor behaviour.The primary question of the study is: which factors do operating people in the financial sector consider themselves to be influenced by? The purpose of this study is to investigate the factors which affect the process of creating forecasts or making financial decisions. The study examines in addition if there is a correlation between length of investor experience and overconfidence in forecasting accuracy and investment decision making.The study includes both quantitative and qualitative analysis.

Utveckling av nytt koncept för positioneringsslid
A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.
Bull´s Eye? : Träffsäkerheten i analytikers prognoser
Background: An evaluation of analysts´ forecasting ability is interesting since their estimates constitute an important part in stock valuation and investment decisions. The recent years´ development in the stock market has lead to criticism of analysts? deficient forecasts. Purpose: The purpose of this thesis is to evaluate analysts´ forecasting ability concerning companies quoted at Stockholmsbörsen between 1987 and 2002. We also intend to discuss possible explanations for analysts? behavior in case of deficient accuracy.

Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning
Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.
Does it make sense? : En studie om implementeringen av komponentavskrivningar
Det finns lagar som reglerar hur företagen ska upprätta och slutföra sin redovisning och hur redovisningen utvecklas är ett ständigt pågående arbete. Bokföringsnämnden har sedan 2004 arbetat med att ta fram förenklade regler för svenska onoterade företag som benämns K-regelverket och har som syfte att underlätta för företagen i sin redovisning. Studien fokuserar på hur materiella anläggningstillgångar ska redovisas efter anvisningarna i K3.Värderingsförutsättningarna för materiella anläggningstillgångar har ändrats i och med en reglering i K3. Tillgångens anskaffningsvärde ska fördelas på komponenter istället för att redovisas som en helhet, detta för att tydligare spegla tillgångens förbrukningskapacitet. För att dela upp en tillgång ska komponenterna ha betydande värde i förhållande till tillgångens totala anskaffningsvärde.
Bestämning av vattenytor med hjälp av Nätverks-RTK och totalstation : Inmätning av Karlbergsån i Grums kommun
This report is presenting an approach that can be used to measure water surfaces in difficult conditions caused by dense vegetation and lack of nearby known points. The objective was to make a contribution to necessary measures for adaptation against floods in Grums Municipality along the stream Karlbergsån, which may occur when persistent rain raises the level of the stream. Along the river there are low-lying areas prone to flooding. According to Grums Municipality, the stream may widen where the water level differences are large, to create a better flow path and to counteract flooding. Grums Municipality was also interested in survey stormwater discharges which may affect the water level in the stream.
Stereoseende i realtid
In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..
