1. Vibrational energy harvesting for sensors in vehicles
Sammanfattning : The miniaturization of semiconductor technology and reduction in power requirements have begun to enable wireless self-sufficient devices, powered by ambient energy. To date the primary application lies in generating and transmitting sensory data. LÄS MER
2. Torsional vibration absorbers in heavy-duty truck powertrains
Sammanfattning : The heavy-duty vehicle manufacturers face large challenges when it comes to reducing CO2 emissions from vehicles. The ongoing development of more efficient combustion engines leads to an increase in torsional vibrations. LÄS MER
3. Waves and Trajectories in Quantum Dots
Sammanfattning : This thesis deals with electron transport in low-dimensional semiconductor nanostructures,and in particular, systems with quasi zero-dimensional properties, called quantum dots. These systems are so small that the electron wavelength is comparable to the size of systems, which means that the wave nature of the electrons is of fundamental importance. LÄS MER
