Extracting Steady State Components from Synchrophasor Data Using Kalman Filters

open access: yesEnergies, 2016
Data from phasor measurement units (PMUs) may be exploited to provide steady state information to the applications which require it. As PMU measurements may contain errors and missing data, the paper presents the application of a Kalman Filter technique ...

Domain engineered gallium oxide phototransistors enabling intelligent ultraviolet vision with dynamic gating

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
Single‐domain Si‐doped β‐Ga2O3 thin films grown on off‐axis sapphire eliminate domain boundaries, improving transport and photogating. Gate‐pulse modulation suppresses persistent photoconductivity, yielding ultrafast response and high detectivity. Integrated into a 24 × 24 array, the devices enable high frame rate DUV imaging and energy‐efficient ...

Exercise‐induced dynamic hyperinflation in chronic obstructive pulmonary disease

open access: yesExperimental Physiology, Volume 111, Issue 5, Page 2476-2484, 1 May 2026.
Abstract Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease caused by inhalation of noxious particles, most commonly cigarette smoking. The consequent changes in airways, lung parenchyma and pulmonary vasculature lead to increased resistive, elastic and threshold loads and impaired capacity of the respiratory muscle pump. COPD

Parallel Factor-Based Model for Two-Dimensional Direction Estimation

open access: yesInternational Journal of Antennas and Propagation, 2017
Two-dimensional (2D) Direction-of-Arrivals (DOA) estimation for elevation and azimuth angles assuming noncoherent, mixture of coherent and noncoherent, and coherent sources using extended three parallel uniform linear arrays (ULAs) is proposed.
