1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER
2. Volumetric Rendering of the Inner Coma of a Theoretically Modelled Comet for Comet Interceptor Mission
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The Comet Interceptor is a joint mission by European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) which seeks to perform a flyby over a Long Period Comet using a multi-element spacecraft. The Comet Interceptor comprises three spacecrafts- A, B1 and B2. LÄS MER
3. Evaluation of algorithms for accurate micro-doppler effects measurement in FMCW radar
Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : Micro-Doppler effects are phenomena that occur because of micro-motion. A micro-motion is either a vibration, rotation, or acceleration which is small relative to the motion of the target. These effects can be used in order to characterize a target through their signature movement. LÄS MER
4. Distance-Based Formation Control, Maneuvering and Flip Ambiguity Avoidance in Multi-Agent Systems
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Formation control is a fundamental concept in the field of robotics, where a group ofagents is directed to achieve a specific formation or pattern. This report investigates decentralizeddistance-based formation control strategies for multiagent formation control, with a focus on controllaw design dealing with flip ambiguity issues, and centroid maneuvering.

5. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Sublevel caving operations at great depths are subjected both to large stress concentrations that are redistributed as the mining front progresses and to mining-induced seismicity. This is the case for Kiirunavaara mine, Sweden’s largest underground mine. LÄS MER
