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. Quantum Optical Description of High-order Harmonic Generation

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Isabel Moreno; [2024]
   Keywords : Physics and Astronomy;

   Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

4. 3. Developing a portable, customizable, single-channel EEG device for homecare and validating it against a commercial EEG device

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

   Author : Máté Károly Tóth; [2023]
   Keywords : Electroencephalography EEG ; Portable EEG; Single-channel EEG; Commercial EEG; Brain-machine interface; Prototype development; Elektroencefalografi EEG ; Bärbar EEG; Enkanaligt EEG; Kommersiellt EEG; Hjärna-maskin-gränssnitt; Prototyputveckling;

   Abstract : There are several commercial electroencephalography (EEG) devices on the market; however, affordable devices are not versatile for diverse research applications. The purpose of this project was to investigate how to develop a low-cost, portable, single-channel EEG system for a research institute that could be used for neurofeedback-related applications in homecare.

5. 4. Harmonisk strömsimulering i inverterbaserade värmepumpar

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alexander Magnusson; [2023]
   Keywords : Current harmonics; inverter-driven compressor; black box simulation;

   Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

6. 5. Mapping of IPM machine efficiency and Noise Vibration Harshness : An investigation into trade-offs with respect to efficiency and Noise Vibration Harshness

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

   Author : Bix Eriksson; Erik Rudqvist; [2023]
   Keywords : ;

   Abstract : Due to the recent shift towards electrification, electric machines has become a prominent option to be used in vehicle applications. Much effort is spent in the development process of these machines to make optimizations in order to improve the performance aspects of the machine. READ MORE
