31. Quantum electronic transport in low-dimensional semiconductors
Sammanfattning : Electronic transport is studied at low temperatures in two-dimensional electron gases (2DEGs) and in mesoscopic semiconductor microstructures. The method of microwave-detection of the Shubnikov-de Haas effect for the contact-free characterisation of transport properties of 2DEGs is explored using both magnetic-field modulation and light-induced carrier modulation.

32. Numerical Studies of Methanol PPC Engines and Diesel Sprays
Sammanfattning : The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). LÄS MER
33. Learning from Interactions : Forward and Inverse Decision-Making for Autonomous Dynamical Systems
Sammanfattning : Decision-making is the mechanism of using available information to generate solutions to given problems by forming preferences, beliefs, and selecting courses of action amongst several alternatives. In this thesis, we study the mechanisms that generate behavior (the forward problem) and how their characteristics can explain observed behavior (the inverse problem). LÄS MER
34. A pressure coupled Representative Interactive Linear Eddy Model (RILEM) for heavy-duty truck engine combustion simulations
Sammanfattning : Internal combustion engines (ICE) are frequently debated due to their environmental consequences. Although the switch to electromobility is currently happening for light and medium-duty vessels, the transition for ships and heavy-duty trucks is more complex. The primary problem in the shift is the incapability of matching the range of ICE. LÄS MER
35. Charge transport in III-V narrow bandgap semiconductor nanowires
Sammanfattning : This thesis describes charge transport in III-V narrow bandgap semiconductor nanowires. We are particularly interested in quantum transport in InSb, InAs and InP-InAs core-shell nanowires. According to the type of transport mechanism dominating in the devices, this thesis can be divided into four parts. LÄS MER
