Consider an information network with harmful procedures called attackers (e.g., viruses); each attacker uses a probability distribution to choose a node of the network to damage. Opponent to the attackers is the system protector scanning and cleaning from attackers some part of the network (e.g., an edge or a path), which it chooses independently using another probability distribution. Each att...

The fluctuation of normal leakage current has a great influence on the fixed-threshold protector. To address this issue, paper proposes an adaptive protection method based sparrow search algorithm (SSA)-backpropagation (BP) neural network. Based analysis generation mechanism, uses SSA optimized BP network to construct prediction model current. By dividing range into several intervals and settin...

As far as the design of SPDs is concerned, the need exists for simplifying its circuit structure in fulfilment of the prerequisite condition of protective reliability. The circuit simplification for SPDs is of benefit to lower the cost of manufacture and reduce the size of chassis. Considering that the traditional SPD that has been extensively used on single-phase AC power supply lines requires...

Origin of Mentoring1 The Greek poet Homer describes Odysseus, king of Ithaca, as having a loyal friend and advisor by the name of Mentor. While Odysseus was away fighting in the Trojan War, Mentor became a trusted teacher, coach, counselor, and protector of Odysseus’ son Telemachus. Thus, the word “mentor” used today derives from Homer and reflects a process where the mentor guides and protects...
