By analyzing nonlinear and nonstationary vibration signals from the spindle device of the mine hoist, it is a challenge to overcome the difficulty of fault feature extraction and accurately identify the fault of rotor-bearing system.In response to this problem, this paper proposes a new approach based on variational mode decomposition (VMD), SVM, a
Abstract Power utilities desire an alternate noninvasive test method for assessing the diagnostic status of power apparatus.The primary reason is to minimize the economic constraints and ensure lifetime and reliability of power apparatus within shorter duration.In this context, frequency response analysis (FRA) method is increasingly Accent Table r
In this study, a two-dimensional depth-integrated non-hydrostatic wave model is developed.The model solves the governing equations with hydrostatic and non-hydrostatic pressure separately.The velocities under hydrostatic pressure conditions are firstly obtained and then modified HYGIENE using the biconjugate gradient stabilized method.The hydrostat
Objective: to evaluate the impact of oxidative Suction Tube stress intensity on hemorheological parameters in acute poisonings by psychopharmacological agents.Subjects and methods.The blood values of lipid peroxidation (LPO) and the antioxidant system (AOS), and hemorheological parameters were determined in 196 patients with acute poisoning by psyc
