1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Nipon Roy; [2023]
   Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Abstract : 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. READ MORE

3. 2. Volumetric Rendering of the Inner Coma of a Theoretically Modelled Comet for Comet Interceptor Mission

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Amal Vinod; [2023]
   Keywords : Volumetric rendering; rendering; Comet; Coma; Dust Coma; Gas Coma; Blender; Comet Interceptor;

   Abstract : 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. READ MORE

4. 3. Evaluation of algorithms for accurate micro-doppler effects measurement in FMCW radar

   University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Author : Morgan Agerstig Rosenqvist; [2023]
   Keywords : Radar; FMCW; micro-Doppler; RPM;

   Abstract : 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. READ MORE

5. 4. Distance-Based Formation Control, Maneuvering and Flip Ambiguity Avoidance in Multi-Agent Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Kristoffer Germalm; Yassir Fiddi; [2023]
   Keywords : ;

   Abstract : 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.

6. 5. Evaluation of structurally controlled rockfall hazard for underground excavations in seismically active areas of the Kiirunavaara mine

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Manuel Alberto Fuentes Espinoza; [2023]
   Keywords : Structurally controlled rockfalls; rockfalls due to seismic shaking; sublevel caving; fork layout; Unwedge; wedge analysis; deterministic analysis; probabilistic analysis;

   Abstract : 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. READ MORE
