1. 16. Human Body Presence Detection in Water Environments Using Pulse Coherent Radar

   University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

   Author : Jens Moths; Frotan Frotan; [2022]
   Keywords : presence detection; dead man s grip; micro; mmwave; radar; radome; a111; acconeer; radinn; direct leakage; electric surfboard; närvaro detektering; dödmansgrepp; micro; mmwave; radar; radome; a111; acconeer; radinn; direktläckage; elektrisk surfbräda;

   Abstract : New technology in radar opens up new possibilities for cheap and easily integrated human body presence detection. In this work, we aim to make a proof of concept that replaces the "dead man’s grip" on an electric surfboard with a more convenient wireless system based on micro radars. READ MORE

3. 17. FMCW mmWave Radar for Detection of Pulse, Breathing and Fall within Home Care

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

   Author : Axel Trange; [2021]
   Keywords : ;

   Abstract : Countless of elderly people fall and get hurt within their homes, worldwide, every year, and as they can not always reach out for help themselves, they end up helplessly waiting for someone to notice what has occurred. Throughout this work, it is investigated if remote sensing of the mmWave FMCW radar IWR6843AOPEVM can be adopted to detect the incident of falls, and also detect the vital signs of the human subject.

4. 18. Simulation of birefringence effects for high-energy neutrino detectors

   University essay from Uppsala universitet/Högenergifysik

   Author : Nils Heyer; [2021]
   Keywords : astroparticle physics; radio detection; high-energy neutrinos; birefringence;

   Abstract : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. READ MORE

5. 19. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Bakhtiar Afzalan; [2021]
   Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

   Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

6. 20. Test setup for LDMX HCal readout

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Joshua Greaves; [2020]
   Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

   Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.
