Unlike sleep-walkers, patients with rapid-eye-movement-behaviour disorder (RBD) rarely leave the bed during the re-enactment of their dreams. RBD movements may be independent of spatial co-ordinates of the ‘outside-world’, and instead rely on (allocentric) brain-generated virtual space-maps, as evident by patients’ limited truncal/axial movements....

In microgrids, multiple modular distributed generation (DG) are required to power the system’s loads. Nonetheless, disproportionate reactive power (Q) sharing arises with unequal feeder line impedances of DGs connected to a common bus. Hence, this study proposes a novel method, based on virtual shunt and series capacitances, to regulate both accura...
