1. 1. Motion tracking for virtual reality using inertial motion sensors

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Max Lindgren; Marcus Olsson; [2023]
   Keywords : ;

   Abstract : Human motion capture has until recently been dominated by camera-based solutions. With advancements within Micro Electro-Mechanical Systems (MEMS) technology new Inertial Measurement Unit (IMU) based solutions are being explored. This thesis explores the possibility of using IMUs for augmenting motion tracking for Virtual Reality (VR). READ MORE

3. 2. Design and Qualification of a Gimbal Suspension for Attitude Control System Testing of CubeSats

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

   Keywords : Gimbal; CubeSat; ADCS; Suspension; Testbed; Disturbance Torque; Angular Measurement; Gimbal; CubeSat; ADCS; Upphängning; Testbädd; Störmoment; Vinkelmätning;

   Abstract : Since the dawn of the space race, satellites have grown rapidly in complexity and shrunk equally rapidly in size. Most of them contain an Attitude Determination and Control System (ADCS) on board for pointing and detumbling manoeuvres. READ MORE

4. 3. Online Identification of Running Resistance and Available Adhesion of Trains

   University essay from Fordonssystem

   Author : Jesper Ahlberg; Esbjörn Blomquist; [2011]
   Keywords : running resistance; extended kalman filter; ekf; parameter estimation; acceleration estimation; adaptive models; adhesion; freight trains; numerical differentiation; gångmotstånd; extended kalman filter; ekf; parameterskattning; accelerationsskattning; adaptiva modeller; adhesion; godståg; numerisk derivering;

   Abstract : Two important physical aspects that determine the performance of a running train are the total running resistance that acts on the whole train moving forward, and the available adhesion (utilizable wheel-rail-friction) for propulsion and breaking. Using the measured and available signals, online identification of the current running resistance and available adhesion and also prediction of future values for a distance ahead of the train, is desired.
