Small Signal Stability of a Power System

International Journal of Recent Technology and Engineering (IJRTE), 2019
Power system (PS) stability is a major concern for an electrical power system (PS) in the past decades. Small signal stability (SSS) is a class of stability of the power system (PS) determined by eigenvalue analysis. The dynamic performance of the linearized power system (PS) model is determined by small signal stability (SSS) analysis by calculation ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching
