1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : 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. LÄS MER
2. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : 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. LÄS MER
3. Design of radio frequency energy harvesting system : for use in implantable sensors
Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakultetenSammanfattning : 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. LÄS MER
4. Evaluation of Discrete-Time Wideband Receivers for NB-IoT
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : 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. LÄS MER
5. Investigation of ECG electrodes for burn wounds
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för elektroteknikSammanfattning : 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.
