1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Muhammad Umar Farooq; [2023]
   Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

   Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces.

3. 2. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Eric Schyllert; [2023]
   Keywords : Technology and Engineering;

   Abstract : The main goal with the thesis was to design, construct and evaluate a system able to drive and brake a mechanical axis to simulate loads and stored rotational energy - a hardware force simulator. The force simulator was then to be integrated in a existing hardware-in-the-loop testing rig to enhance the mechanical dynamics of door simulations. READ MORE

4. 3. Design of radio frequency energy harvesting system : for use in implantable sensors

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Amir Ebrahimi; David Kihlberg; [2022]
   Keywords : RF energy harvesting; RF rectifier; efficiency; voltage sensor; voltage doubler;

   Abstract : Implantable biomedical wireless sensors provide monitoring of vital health signs such as oxygen, temperature and intraocular pressure and may help to analyse and detect diseases in humans and animals. However, one of the design challenges of implantable devices is providing a safe and reliable energy source. READ MORE

5. 4. 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

6. 5. Investigation of ECG electrodes for burn wounds

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Linus Falk; [2020]
   Keywords : ECG; electrode; burn; wound;

   Abstract : This project aims to investigate a variety of electrodes for ECG (electrocardiogram) measurements and find suitable ones for burn wounded skin in association with the Burn center in Uppsala University Hospital.   To this purpose, the electrical properties (in particular, electrical impedance and equivalent circuit) of electrodes and the influence of the skin on the electrical properties are looked into, and various common artefacts in ECG measurements are investigated, such as wandering baseline (caused by perspiration, respiration, patient movement and poor electrode contact), muscle tremor artefact, 50-60 Hz power line interference and measurement noise.
