A Hierarchical Self-Adaptive Data-Analytics Method for Real-Time Power System Short-Term Voltage Stability Assessment [PDF]

, 2018
As one of the most complex and largest dynamic industrial systems, a modern power grid envisages the wide-area measurement protection and control (WAMPAC) system as the grid sensing backbone to enhance security, reliability, and resiliency.

Short-Term Voltage Stability Enhancement in Residential Grid with High Penetration of Rooftop PV Units

, 2019
© 2010-2012 IEEE. Short-term voltage instability (STVI) imposes a severe threat to modern distribution networks (DNs) where a large number of intermittent distributed generator (DG) units, like rooftop photovoltaic (PV), is being integrated. Consequently,

A super-resolution perception-based incremental learning approach for power system voltage stability assessment with incomplete PMU measurements

, 2021
This paper develops a fully data-driven, missing- data tolerant method for post-fault short-term voltage stability (STVS) assessment of power systems against the incomplete PMU measurements. The super-resolution perception (SRP), based on a deep residual

HD‐DRUM Rhythmic Training in Huntington's Disease: Feasibility, Motor, and Brain Microstructural Pilot Signals

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Rhythmic cuing may benefit motor functions in Huntington's disease (HD) by compensating for the loss of predictive timing associated with basal ganglia degeneration. To our knowledge no remote rhythmic training application has been developed or evaluated that seeks to improve function in HD.

The Forthcoming General Election in the Republic of Ireland: Winds of (Left‐Wing) Change or Plus Ça Change?

The Political Quarterly, Volume 96, Issue 1, Page 180-188, January/March 2025.
Abstract The forthcoming general election will be the most consequential electoral contest for the Republic of Ireland in a century. The polity is situated in truly novel territory with the potential for an historic first: the incoming of a Sinn Féin‐led, left‐wing government.
