1. 16. Capacitive Micromachined Ultrasonic Transducers for Underwater Applications

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Patrick Johansson; [2021]
   Keywords : CMUT; capacitive; micromachined; ultrasonic; transducer; model;

   Abstract : Capacitive micromachined ultrasonic transducers (CMUT:s) are often used in medical imaging and they show some promise as underwater transducers. This thesis collates the available information about how CMUT:s operate, their strengths and weaknesses and investigates their efficiency as an underwater transducer. READ MORE

3. 17. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Magnus Wasting; [2021]
   Keywords : Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

   Abstract : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. READ MORE

4. 18. Tests of Series Arcing and Arc Fault Detection Devices in Low Voltage Systems

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

   Author : Ghazal Al Qabbani; [2021]
   Keywords : ;

   Abstract : Unwanted electrical arcs are a concern in fire and electrical equipment safety. Arcs in electrical systems can be categorized into two main groups, traditionally called: Series and parallel arc faults, or more recently called low current and high current arc faults. READ MORE

5. 19. Model verification and common mode current analysis of grid connected three phase two level converters

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Simon Lindvall; Richard Haraldsson; [2021]
   Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

   Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE

6. 20. Review of ElectricRoad Systems : Both a conventional and innovative technology

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Sam Schaap; [2021]
   Keywords : ;

   Abstract : A more sustainable society can be accomplished by electrifying the road transportation sector, which the year 2016 emitted 11,9 \% of the global greenhouse emissions. To accelerate this transformation, dynamic charging via electric road systems (ERS) can be implemented, allowing electric vehicles (EV) to become cheaper and achieve lower energy consumption thanks to smaller batteries.
