In this article the natural convection of nano-fluid water - copper in a square cavity has been studied numerically.The left wall is maintained at high temperature ,right wall is maintained at NO-POO DECADENCE low temperature and the other walls are adiabatic.The numerical model is based on the SIMPLE algorithm is used to solve the equations of con

Abstract To solve the problem of air gap eccentric fault of traction motor, the fault characteristic frequency is close to the fundamental frequency, and the decomposed frequency affects each other, which is easy to cause spectrum aliasing.A reconstruction of variational mode decomposition method is proposed (reconstructed variational mode Energy d

The switched reluctance motor (SRM) has many merits, such as robustness, a simple construction, low cost, and no permanent magnets.However, its deployment in servo applications is restrained due to acoustic noise and torque ripple (TR).This paper presents a new torque control approach for TR reduction in Baby switched reluctance drives.The approach

The Braconidae are a megadiverse and ecologically highly important group of insects.The vast majority of braconid wasps are parasitoids of other insects, usually attacking the egg Recycling Tools or larval stages of their hosts.The ovipositor plays a crucial role in the assessment of the potential host and precise egg laying.We used light- and elec

Budding yeasts are highly suitable for aging studies, because the number of bud scars (stage) proportionally correlates with age.Its maximum stages are known to reach at 20-30 stages on an isolated agar medium.However, their stage dynamics in a liquid culture is virtually unknown.We investigate the population dynamics by counting scars in each cell
