Evaluation of Remotely Sensed Inundation Data Sets to Estimate Flood‐Associated Emergency Department Visits After Hurricane Harvey

open access: yesGeoHealth
Floods can increase the risk of adverse health outcomes through multiple pathways, including contamination of food and water. Remotely sensed (RS) inundation extents can help identify regions with expected heightened flood‐related health risks, but ...

Age Replacement for Balanced Systems Under Mission Durations

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT With advances in technology, systems such as Unmanned Aerial Vehicles (UAV) and planetary landing vehicles whose operation requires maintaining balance across sectors have attracted increasing attention within the balanced systems literature.

How Does Our Degrading System Perform?

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT We discuss the quality of performance of degrading systems when degradation is modeled by a stochastic process with independent increments and increasing sample paths. As an example, the gamma process is considered. First, for the continuously observed degradation, by comparing with the black‐box scenario (without observing degradation), the ...

Uncertainty Evaluation for Testing and Calibrating Mobile Sensors Only Using Short Collocation Periods

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Low‐cost sensors are increasingly being used, and also considered for usage in regulatory contexts like air quality monitoring. Proper sensor calibration and uncertainty evaluation is necessary in such cases. With the advance of mobile sensors, for example, installed on top of a car, new test and calibration paradigms are required, in ...

Optimal Design of Multiple Moving Average Charts

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT The moving average control chart has been used to detect changes in a process mean more quickly than the Shewhart chart. The MA chart takes an unweighted average of the most recent w$w$ values and uses this to make an inference regarding the stability of the process.

High‐Dimensional Cumulative Sum Control Charts for Industrial Measurement Systems

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT High dimensional sensing in modern factories and energy assets produces thousands of correlated signals. Detecting small process shifts is challenging because many classical multivariate charts lose power or become unstable. We present two cumulative sum procedures for two sample monitoring that remain effective when the number of variables is

A Case Study to Monitor Parallel‐Connected Ni–Cd Batteries on EMU Trains Through Compositional Data Control Charts

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Electric multiple unit (EMU) trains, widely used in modern railway transportation, use Nickel–Cadmium (Ni–Cd) batteries to power auxiliary systems on board, including lighting, ventilation, control electronics, and emergency systems. These batteries are often connected in parallel to ensure a wider power supply range for electrical loads that ...

Frequency Shaping for Improving a Trade‐Off Between Control and Privacy Performance: Beyond Differential Privacy

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...

Low‐Complexity Hybrid Beamforming for LEO Satellites: Beam Update Rate Analysis and Advanced Adaptive Precoding

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite constellations offer unprecedented opportunities for global broadband connectivity but pose significant beamforming challenges due to rapid platform motion and stringent onboard hardware constraints. Fully digital architectures, while optimal in theory, remain impractical for satellite payloads, motivating ...
