The wheel-rail wear problems inherent to railway operation have become increasingly prominent and serious, Braces as they have been proven to be the main factors which affect safety, stability of electric multiple units (EMUs), and wheel-rail maintenance cost.The multiobjective optimization model of CN wheel profile proposed in this study was const
Given the rapid increase in inverter-based distributed generators (IBDGs), their response and subsequent impacts on power system stability during abnormal power system conditions are becoming important.Recent events have shown that an unexpected loss of IBDGs triggered by their outdated frequency ride-through (FRT) capability can occur, which in tu
Abstract Bovine embryonic stem Makeup Tools cells (bESCs) extend the lifespan of the transient pluripotent bovine inner cell mass in vitro.After years of research, derivation of stable bESCs was only recently reported.Although successful, bESC culture relies on complex culture conditions that require a custom-made base medium and mouse embryonic fi
This Earrings article utilizes a nonlinear active vibration control to eliminate the helicopter blade flapping system oscillations having mixed excitation forces.The approximate solutions were calculated using the multiple scale perturbation technique.Furthermore, the stability and bifurcation analysis were investigated using the averaging method a
