Fault Diagnosis for Variable Frequency Drive-Fed Induction Motors Using Wavelet Packet Decomposition and Greedy-Gradient Max-Cut Learning

In this paper, a novel fault diagnosis method for variable frequency drive (VFD)-fed induction motors is proposed using Wavelet Packet Decomposition (WPD) and greedy-gradient max-cut (GGMC) learning algorithm.The proposed method is developed using experimental stator SCALP.SPA SCRUB current data in the lab for two 0.25 HP induction motors fed by a

Cigarette Smoke Exposure Leads to Organic and Mineral Bone Component Changes: The Importance of Rho Kinase Function in These Events

Aberrant Rho-associated kinase function could be associated with increased bone fragility.Since cigarette smoke (CS) exposure promotes the increase in bone fragility due to changes in bone tissue components, this study aimed to investigate how CS exposure could modulate the Rho kinase-associated bone structural changes.Mice were assigned to four gr

A Numerical Investigation of Thermal-Induced Explosive Spalling Behavior of a Concrete Material Using Cohesive Interface Model

Thermal-induced spalling is a typical failure behavior of concrete materials exposed to high temperatures.This study uses Abaqus to establish a numerical model of concrete material comprising aggregates and mortar matrix.Cohesive elements considering heat conduction are embedded into this numerical model to simulate the thermal-induced explosive sp
