Modelling line emission in the lower solar atmosphere
… oxygen, to account for its effects on electron impact ionisation and dielectronic recombination. New calculations are made for electron impact ionisation from long-lived metastable levels, which become populated at these densities. Other atomic processes not normally included in the coronal …

Transmission Capacity Improvement for Single Photon Avalanche Diode-based Optical Communication Using PAM Modulation
This dissertation investigates the potential transmission capacity improvement in optical communication links due to the use of single photon avalanche diode (SPAD) optical receivers. Currently, for non-optically amplified optical communication links that use intensity modulation with direct …
