IEEE Open Journal of the Industrial Electronics SocietyMetal oxide varistor (MOV) is a nonlinear resistive element whose resistance decreases rapidly when the applied voltage exceeds a threshold value. A dc solid-state circuit breaker (SSCB) uses MOVs or MOV with resistor-capacitor-diode (RCD) snubber ...

MOV-Modified-FxLMS Algorithm With Variable Penalty Factor in a Practical Power Output Constrained Active Control System [PDF]
IEEE Signal Processing Letters, 2023 Practical Active Noise Control (ANC) systems typically require a restriction in their maximum output power, to prevent overdriving the loudspeaker and causing system instability. Recently, the minimum output variance filtered-reference least mean square (

Use of a convolutional neural network to segment signals of motor operated valves [PDF]
Nuclear Energy and Technology, 2021 Motor operated valves (MOV) are one of the most numerous classes of the nuclear power plant components. An important issue concerned with the MOV diagnostics is the lack of in-process (online) automated control for the MOV technical condition during full

The Impact of the Madden‐Julian Oscillation on the Formation of the Arabian Sea Monsoon Onset Vortex
Geophysical Research Letters, 2023 During certain years, a synoptic scale vortex called the monsoon onset vortex (MOV) forms within the northward advancing zone of precipitating convection over the Arabian Sea. The MOV does not form each year and the reason is unclear.
