Competition between native and alien species is often described as a main driver Mechanical Drain Pump of biodiversity loss.Nevertheless, there is limited evidence of animal declines and extinctions actually determined by competition.The Aeolian lizard, Podarcis raffonei, is critically endangered because it suffered dramatic declines and extinction
Aiming at the problem of large torque ripple and low efficiency of traditional direct instantaneous Shower Gels torque control (DITC) of switched reluctance motor (SRM), an improved DITC method based on adaptive turn-on angle torque sharing function (TSF) is proposed.This method not only introduces TSF, but also divides a working cycle into six sec
In order to improve the prediction accuracy of gas emission in the mining face, a method combining least absolute value convergence and selection operator (LASSO), whale optimization algorithm (WOA), and extreme gradient boosting (XGBoost) was proposed, along with the LASSO-WOA-XGBoost gas emission prediction model.Aiming at the Pre-Packs- Eye And
