1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : 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.

2. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : 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. LÄS MER
3. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : 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. LÄS MER
4. Superconducting gates for InP HEMTs
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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. LÄS MER
5. Analysis to reduce ice-related production losses for wind turbines
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. LÄS MER
