Wheat (Triticum aestivum L.), a staple grain consumed worldwide, is heavily affected by Fusarium species, which cause harmful diseases that threaten its production.The present study was conducted to investigate the biocontrol activity of monocultures of Pseudomonas protegens ML15 and Trichoderma koningiopsis Tr21 as well as their co-culture, as a s

The wheel-rail vibration signal of metro vehicle has the following characteristics: low signal to noise ratio, nonlinear, nonstationary and so on.To achieve better extraction to the fault feature of flat wheel, a fault diagnosis method of metro vehicle flat wheel based on envelop spectrum entropy and Variational Mode Decomposition (VMD) was propose
