Transient Process Optimization for Dual-Arm Cluster Tools With Wafer Revisiting

open access: yesIEEE Access, 2021
In wafer fabrication, it is imperative to minimize the transient process of cluster tools for the sake of on-demand and preventive maintenance. Due to the trend of multi-type and small-batch production, transient processes appear more and more frequently.

Pressure Analysis in the Draft Tube of a Pump-Turbine under Steady and Transient Conditions

open access: yesEnergies, 2021
Pumped-storage power stations play a regulatory role in the power grid through frequent transition processes. The pressure pulsation in the draft tube of the pump-turbine under transient processes is important for safe operation, which is more intense ...

Study of Electromagnetic and Thermal Transients in a High-temperature Superconducting Transformer during a Short Circuit [PDF]

open access: yesProblems of the Regional Energetics, 2023
Today, high-temperature superconducting (HTS) current limiters and transformers allow to limit the surge short circuit current during failure without negatively affecting on the power grid com-plex at the normal operation mode. However, the transition of

Optical inter-site spin transfer probed by energy and spin-resolved transient absorption spectroscopy [PDF]

open access: yes, 2020
Optically driven spin transport is the fastest and most efficient process to manipulate macroscopic magnetization as it does not rely on secondary mechanisms to dissipate angular momentum. In the present work, we show that such an optical inter-site spin
