Abrupt ending of the Madden–Julian Oscillation by convectively coupled Kelvin wave precipitation leaves a swath of flooding across Indonesia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
During July 2021 there were widespread reports of flooding across the equatorial Maritime Continent. This analysis reveals how interactions between a system of convectively coupled Kelvin waves (CCKWs) and diurnally phase‐locked westward‐propagating inertio‐gravity waves during an active Madden–Julian Oscillation (MJO) caused these extreme rainfall ...

Novel Calibration Strategy for Kalman Filter‐Based Measurement Fusion Operation to Enhance Aging Monitoring

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT This study introduces a novel calibration strategy for the linear Kalman filter (LKF) fusion application in condition monitoring, specifically utilizing accelerated aging data. Unlike the existing literature that often focuses on complex nonlinear Kalman filter variants, this research delves into the calibration of LKF.

Statistical Complexity of Quantum Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...

Innovation and adaption in local governments in the face of COVID‐19: Determinants of effective crisis management 地方政府面对新冠肺炎时的创新与适应措施:有效危机管理的决定因素 Innovación y adaptación en gobiernos locales frente al COVID‐19: Determinantes de una gestión eficaz de la crisis

open access: yesRisk, Hazards &Crisis in Public Policy, EarlyView.
Abstract Local governments were instrumental in managing the COVID‐19 crisis in countries worldwide. This study examines the methods that local governments in Israel used to successfully manage the COVID‐19 crisis. We explored the structural characteristics of the localities that excelled at managing the pandemic.

A Fully Automated Robotic System for Tuning Optimization of RF Cavity Filter

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The advancements in radar systems, electronic warfare, and telecommunication industries have generated a substantial demand for microwave filters. Among these, cavity filters have conventionally served in transmitters and receivers, facilitating the passage of desired signals in the passband while effectively rejecting harmonics and spurious ...

Quantifying range‐ and topographical biases in weather surveillance radar measures of migratory bird activity

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We compared local density measures of migratory birds collected using a mobile, vertically looking radar with reflectivity from a Next Generation Weather Radar (NEXRAD) station across varying distances and topographies. Broadly, mean nightly migration activity and within night migration activity between NEXRAD and the mobile radar were strongly ...

A comparison of established and digital surface model (DSM)‐based methods to determine population estimates and densities for king penguin colonies, using fixed‐wing drone and satellite imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We used fixed‐wing drones and Beyond Visual Line of Sight flying to create high‐resolution imagery and Digital Surface Models (DSMs) of six large king penguin colonies (colony population sizes ranging from 10,671 to 132,577 pairs) in South Georgia. We used a novel DSM‐based method to facilitate automated and semi‐automated counts of each colony to ...
