Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen
This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..
Fjärrstyrning av videokamera
On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.
Omega System Kalibrering: Strål X-Separation mätning och kalibrering
Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.
Narrativ i visuell media
Denna undersökning omfattar kamerans inverkan på narrativet i visuella medium. Syftet är att få en insikt i hur kunskap om kameratekniker och ?vinklar påverkar hur åskådaren uppfattar vad regissören vill förmedla, och undvika att fokus sätts på element i filmscener som riskerar att förvirra åskådaren. För att undersöka detta problemområde har litteratur om filmhistoria och kamerateknik använts för att sammanfatta kunskap om hur kameran skall användas, för att förmedla relevant information och bygga upp den effekt som regissören strävar efter. Informationen utifrån detta har därefter tjänat som utgångspunkt för att skapa en kort animerad film med rymdtema där kameran eftersträvar att leverera en konkret visuell upplevelse där vinklar används för att understryka vad varje scen vill förmedla.

Modellering av hydrauliskt aktuatorsystem
This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.
Aktivering av trafiksäkerhetskameror : En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige
During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.
Implementation av XCP över Ethernet
Världen blir mer och mer datoriserad, detta gäller inte minst olika typer av fordon. Datorerna i fordonen blir allt mer avancerade. Detta har lett till att de verktyg som används för utveckling av dessa datorer inte längre klarar av att hantera de allt större datamängderna som genereras. För att råda bot på detta valde BAE Systems att implementera ett nytt protokoll för kommunikation med datorerna i fordonen, nämligen XCP (Universal Calibration Protocol). Genom att implementera XCP över Ethernet går det att överföra betydligt större datamängder än tidigare, då man använde CCP (CAN Calibration Protocol), som använder sig av CAN bussen (Controller Calibration Protocol) istället för Ethernet.
Monitoring lion movements
Prevention of lion predation towards African livestock is of great importance due to the economical losses farmers have because of this. Predation is also one of the main reasons for human-wildlife conflicts and lions often get killed because of it. Therefore, a pilot study using camera traps was conducted to monitor movements of lions and other wildlife through a wildlife corridor in Ol Pejeta Conservancy. The results were compared with a previous study that counted prints in the soil in front of the corridor. Due to theft risk the cameras had to be taken down and pictures were only collected from nine days.
Karakterisering av bioslam för modellering av biogasproduktion
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.
?Film ?r ju ett s?tt att kommunicera med m?nniskor.? En studie av Naomi Kawases portr?ttering av att vara kvinna i relation till en gemenskap.
By analysing Still the water (2014), Radiance (2017) and True Mothers (2020) by Naomi Kawase this essay will look at her work to see how she portrays the experience of being a woman in relation to her community. Looking into her way of using the camera by applying the theory of haptic visuality allows the spectator to identify themselves in a bodily relationship with the image. By using the camera to closely frame objects of importance for the characters, Kawase leads the spectator to understand the world of the film and enables a more profound understanding of their experience. For the community to be of importance for the women it must be founded in the feeling of security and a confirmation of their feelings. Once secure, the women can express themselves and by that, feminist politics..
Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri
In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

Bildförbättring över en bildsekvens
When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
Undersökning av titanföreningar för tillverkning av standarder vid användning av röntgenfluorescens
SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden.
