Abstract The design and analysis of an ultra wideband aperture antenna with dual-band-notched characteristics are presented.The proposed antenna consists of a circular ring exciting stub on the front side and a circular slot on the back ground plane.By utilizing a parasitic strip and a T-shaped Shelf stub on the antenna structure, two notched bands
Renewable microgrid power systems confront a typical stability challenge due to the deficiency of damping and inertia properties.This stability can be maintained by controlling the parameters of the Power System Stabilizer (PSS) and Virtual Inertia (VI).This paper proposes a new approach for controlling the optimal parameters of PSS and VI in the r
Island tameness results largely from a lack of natural predators.Because some insular rattlesnake populations lack functional rattles, presumably the consequence of relaxed selection from reduced predation, we hypothesized that the Santa Catalina Island, California, USA, population of the southern Pacific rattlesnake (Crotalus helleri, which posses
