Abstract We study the hbl5266ca probability that a horizon appears when concentric shells of matter collide, by computing the horizon wave-function of the system.We mostly consider the collision of two ultra-relativistic shells, both shrinking and expanding, at the moment their radii are equal, and find a probability that the system is a black hole

In a conventional AC distribution system, the conservation voltage reduction (CVR) strategy is widely employed to lower down the voltage of specific load to lower the power consumption.The wide applicability of demand side management (DSM) using CVR in a stand-alone microgrid through peperomia double duty VSI-based energy sources is a thrust area,
