One-handed helical oligo(p-benzamide)s were induced via the domino effect based on the planar-axial-helical chirality relay triggered by a planar chiral transition-metal complex at the terminal position as the single chiral source.

Distributed Generation (DG) is the production of electricity from a variety renewable energy sources that closer to customer and load. The addition distributed generation distribution networks alters characteristics system has an influence on its protection coordination. Relay plays critical function in protecting power various problems. coordination reduces relay operating time avoids failure....

Dynamic spectrum access (DSA) is proposed to deal with the growing shortage of available leased spectrum for wireless communication. We investigate a subset of DSA referred to as dynamic spectrum leasing (DSL). At its core, DSL allows spectrum lease holders and cognitive radios to cooperate in an effort to leverage spatial diversity to improve channel utilization for both parties. In this resea...

among the studies related to power systems are the contingency analysis for judging the system security and short circuit study for relay coordination. due to continuous and repeated performation of these studies for different system configurations, the solution algorithms but also on applied numerical techniques. compensation and partial matrix refactorization are two methods that are often us...

To meet the increased customer demands, microgrid evolved. The structure of changes dynamically due to intermittent nature renewable-based generation, status distributed generator and opening breakers for fault/maintenance. Hence, magnitude fault current is dynamic in nature. In order deal with these changes, this paper addresses an adaptive central controller-based protection relay coordinatio...
