Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
(2020-01-01)
Finned tubes that are widely used in heat exchangers could be susceptible to the flow-excited acoustic resonance that generates intense pressure fluctuations, which may lead to premature fatigue failure of the tubes. This ...
Design and evaluation of solar and geothermal energy systems integrated with Cu-Cl cycle
(2020-09-01)
This thesis study proposes solar and geothermal based three multigeneration systems. System 1 consists of a bifacial photovoltaic (BiPV) plant, multi-effect distillation (MED) desalination unit and, proton exchange membrane ...
Robotic and haptic assistance for kidney access during percutaneous nephrolithotomy
(2021-08-01)
Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure for removing kidney stones. Gaining kidney access is the most challenging task in this procedure and the cause of many complications. This thesis presents ...
Clustering analysis of lock contention fault types using run-time performance metrics for java intrinsic locks
(2022-02-01)
Locks are essential in java-based multi-threaded applications as this mechanism provides a proper solution to synchronizing shared resources. However, improper management of locks and threads can lead to contention; as a ...
