1. Rolling shutter in feature-based Visual-SLAM : Robustness through rectification in a wearable and monocular context
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknikSammanfattning : This thesis analyzes the impact of and implements compensation for rolling shutter distortions in the state-of-the-art feature-based visual SLAM system ORB-SLAM3. The compensation method involves rectifying the detected features, and the evaluation was conducted on the "Rolling-Shutter Visual-Inertial Odometry Dataset" from TUM, which comprises of ten sequences recorded with side-by-side synchronized global and rolling shutter cameras in a single room.

2. Wireless Power Transfer in Cavity Resonator
Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : The purpose of this paper is to achieve wireless power transfer inside a resonating cavity, and thereby apply this to charge batteries. The idea is to convert radio frequency waves into direct current, which can charge the batteries. This was done by creating an LC-antenna, which in turn was connected to a rectifier. LÄS MER
3. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.

4. Undersökning om likströmmars påverkan på jordfelsbrytare
Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologiSammanfattning : Denna rapport är ett examensarbete skrivet av studenter på Högskolan i Halmstad som läser elektroingenjörsprogrammet med inriktning elkraftteknik. Examensarbetet beskriver en undersökning av jordfelsbrytare, med fokus på jordfelsbrytare av typ A och hur deras beteende ändras vid närvaro av likströmmar. LÄS MER
5. Comparison between Active and Passive AC-DC Converters For Low Power Electromagnetic Self-Powering Systems : A theoretical and experimental study of low power AC-DC converters
Kandidat-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : Electromagnetic based energy harvesting systems such as Variable reluctance energy harvesting systems (VREH) have shown to be an effective way of extracting the energy of rotating parts. The transducer can provide enough power to run an electronic sensing system, but the problem arises in finding an efficient way of rectifying that power to generate a stable energy supply to run a system, which this report will investigate.
