1. 6. Gravity and surface tension-driven waves

   University essay from KTH/Teknisk mekanik

   Author : Albin Hedblom; [2022]
   Keywords : Gravity surface waves; capillary-gravity surface waves; dispersion; experiment;

   Abstract : In this thesis, gravity and surface tension-driven water waves are investigated by designing an experimental setup to track wave patterns using a 300 fps high speed camera. This is done to reproduce the theoretical diagram of the dispersion relation for surface waves in different teaching contexts. Surface waves are dispersive, i.e. READ MORE

3. 7. Machine Learning for Radar in Health Applications : Using machine learning with multiple radars to enhance fall detection

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Kristoffer Raskov; Oliver Christiansson; [2022]
   Keywords : Machine learning; RNN; Bi-LSTM; radar; sensor fusion; HAR; fall detection; healthcare monitoring; Maskininlärning; RNN; Bi-LSTM; radar; sensor fusion; HAR; falldetektering; hälsoövervakning;

   Abstract : Two mm-wave frequency modulated continuous wave (FMCW) radars were combined with a recurrent neural network (RNN) to perform fall detection. The purpose was to find methods to implement a multi-radar setup for healthcare monitoring and to study the resulting models’ resilience to interference and other obstacles, such as re-arranging the radars in the room.

4. 8. Fluid Surface Velocity Measurement Using Millimeter-Wave Radar Sensor

   University essay from Lunds universitet/Matematisk statistik

   Author : Gustav Broman; Leo Ghatnekar Nilsson; [2022]
   Keywords : Fluid flow surface measurement; velocity estimation; FFT; fast-time phase change; radar.; Mathematics and Statistics;

   Abstract : Contactless fluid surface velocity measurements with radar technology presents novel ways of determining fluid flow. The Acconeer A121 sensor is used, which is a pulsed coherent 60 GHz millimeter-wave radar, with high accuracy and low energy consumption. READ MORE

5. 9. REMOTE PULSE MONITORING USING MILLIMETER WAVES

   University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper
