  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. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Jakob Gunnarsson; [2023-05-10]
    Keywords : ;

    Abstract : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. READ MORE

  4. 3. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Nils Engman; [2023]
    Keywords : Sensors; IoT; Heat Exchangers; Technology and Engineering;

    Abstract : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. READ MORE

  5. 4. Superconducting gates for InP HEMTs

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Alveteg; [2023]
    Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

  6. 5. Analysis to reduce ice-related production losses for wind turbines

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