Simulation of power station protection equipment
… (obtained under the above conditions) when the transient effect is included. Modelling of a current transformer is included because transformer saturation may occur if the fault current is high, and hence the secondary current is distorted. Experiments were carried out to confirm that distorted …

Optical Precursor Behavior
… and understanding is the ability to describe the transients which occur immediately after the onset of a signal. This thesis examines the transients of such a system when a unit step function is applied. The electromagnetic field is described by an integral resulting from Maxwell’s Equations. It …

Some aspects of stratified flow in closed conduits
… quite contrary to the existing literature. No transient effect was apparent due to the limited length of pipe under investigation. An internal hydraulic jump was created by attaching a dam-shape barrier on the bottom wall of the pipe. A relation of conjugate depth ratio to the discharge ratio …

Transient Phase-Change Effect in Phase-Change Memory Devices
… occurs is still unknown. This work introduces a transient electrical method to relate the phase change phenomenon to the mechanism behind it. In this thesis, PCRAM devices were fabricated with Ge2Sb2Te5 (GST) and AgInSbTe, which are well known nucleation and growth dominated phase change …

Leveraging Human-environment Systems in Residential Buildings for Aggregate Energy Efficiency and Sustainability
… from their own disadvantages, e.g. high cost and transient effect, but also lose aggregate energy saving potential due to the oftentimes-associated single-building-focused view and an isolated examination of occupant behaviors. This dissertation attempts to overcome the limitations of traditional …

An experimental study of flow over a 6 to 1 prolate spheroid at incidence
… stress except in a few special cases. Though the effects of cross-plane separation are substantial and have been recognized for some time, the phenomenon of flow separation over three-dimensional bodies is still far from being completely understood. The flow is so complex that no completely …

Thermohydraulics and suppression of nucleate boiling in upward two-phase annular flow : probing multiscale physics by innovative diagnostics
… was developed to accurately capture this unique transient effect of the disturbance waves on the local heat transfer. The experimental results also suggest a strong dependency of the SNB heat flux and wall superheat on steam quality, with a second-order, weaker dependency on total mass flux. The …

Transient phase change effect in phase change memory devices
… Two time parameters were identified from the transient waveform, namely the delay and current recovery times. The link between crystallization kinetics and the transient phase change effect was established by associating nucleation with delay time and growth with current recovery time. …
