1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   University essay from Umeå universitet/Institutionen för fysik

   Author : Franz Wikner; [2024]
   Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

3. 2. Microstructures and Compressive Strength of Lake Ice in Sweden A structural Documentation and Compressive Strength Analysis of Lake Ice Cores from Uppsala, using the SonReb Method

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Julia Ladefoged; [2023-08-18]
   Keywords : ;

   Abstract : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. READ MORE

4. 3. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Sara Lenman; Sofia Blaad; [2023]
   Keywords : Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

   Abstract : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. READ MORE

5. 4. Control Aid Implementation -Modelling and simulation of triple extruder-

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Karl Langsér; [2023]
   Keywords : Machine Learning; Extruder; Modelling; Simulation; Extreme learning machine; Chemical engineering; Technology and Engineering;

   Abstract : In the production of their High Voltage Direct Current Cables (HVDC) and High Voltage Alternating Current Cables (HVAC), NKT uses triple extruders to create layers of insulation and semi-conduction. A model to predict the effect of extruder inputs on the cable’s insulation and semi-conducting layers has been created and trained to predict the extruder in discrete time. READ MORE

6. 5. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

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

   Author : Jaida Raffelsberger; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".
