Influence of volatile fatty acids on aerobic granular sludge performance and considerations for pre-fermentation

Pre-fermentation of influent has been proposed as a method to improve phosphorus removal capacity, granulation, and simultaneous nitrification denitrification for aerobic granular sludge plants. This thesis sought to determine the influence of increasing VFA concentrations on performance of aerobic granular sludge plants and key considerations...

Single Photon Counting UV Solar-Blind Detectors Using Silicon and III-Nitride Materials

Ultraviolet (UV) studies in astronomy, cosmology, planetary studies, biological and medical applications often require precision detection of faint objects and in many cases require photon-counting detection. We present an overview of two approaches for achieving photon counting in the UV. The first approach involves UV enhancement of photon...

Stability of stone- and dolos-armored rubble-mound breakwater heads subjected to breaking and nonbreaking waves with no overtopping

The purpose of the model investigation reported herein was to obtain design information for stone and dolos armor used on breakwater heads and subjected to breaking waves. More specifically, it was desired to determine the minimum weight of individual armor units (with given specific weights) required for stability as a function of sea-side...
