A distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing…

Synchronverters (also called virtual synchronous generators or virtual synchronous machines) are inverters which mimic synchronous generators (SG) to provide "synthetic inertia" for ancillary services in electric power systems. Inertia is a property of standard synchronous generators associated with the rotating…

The Holocene or Anthropocene extinction is an ongoing extinction event caused by human activity during the current geological epoch, impacting diverse families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, as well as both terrestrial and marine species.
