The instability of power systems comprising multiple LCL-filtered grid-connected dc–ac inverters connected in parallel can be caused by any individual inverter due to mutual coupling through the grid impedance. For the stability analysis of a multi

Instability in multi-paralleled LCL-filtered grid-connected inverters system always presents that each inverter is unstable due to the coupling of grid impedance. During stability analysis of multi-paralleled inverters system, which inverter or inver

In order to verify whether a small-scale rotorcraft can fly on Mars, this paper is proposed to establish a Martian atmosphere simulator and to design a hover test stand for coaxial rotorcraft rotor. Since the ultra-low air density of Mars is approxim

Increase in grain/seed size recurrently features as a key element in the ‘domestication syndrome’ of plants (cf. Zohary and Hopf 2000; Fuller et al. 2014). In the context of its spread across Eurasia, however, the grain size of one of the world's
