Two-stage monitoring design and budgeted condition-based maintenance for LED lighting systems: a gamma-process-based ensemble Kalman filter approach
Haohao Shi, Huy Truong-Ba, Michael E. Cholette +3
Light-emitting diode (LED) luminaires degrade gradually during operation, reducing working plane (WP) illuminance and increasing the risk of inadequate indoor lighting. Because ind…
Coating Breakdown Prediction for Ships and Inspection Planning
Huy Truong-Ba, Michael E. Cholette, Geoffrey Will +1
Marine corrosion significantly reduces a ship's availability, increases costs of operation and could impact safety. Protective coatings mitigate these risks, but their effectivenes…
Gamma Process Degradation Modeling and Performance-Driven Opportunistic Maintenance Optimization for LED Lighting Systems
Haohao Shi, Huy Truong-Ba, Michael E. Cholette +3
LED lighting systems consist of multiple LED luminaires, each subject to gradual package degradation and abrupt driver failures. Their acceptability is governed by long-term spatio…
Sensor Fusion for Track Geometry Monitoring: Integrating On-Board Condition Monitoring and Degradation Models via Kalman Filtering
Huy Truong-Ba, Jacky Chin, Michael E. Cholette +1
Track geometry monitoring is essential for maintaining the safety and efficiency of railway operations. While Track Recording Cars (TRCs) provide accurate measurements of track geo…
A Stochastic-MILP dispatch optimization model for Concentrated Solar Thermal under uncertainty
Navid Mohammadzadeh, Huy Truong-Ba, Michael E. Cholette +2
Concentrated Solar Thermal (CST) offers a promising solution for large-scale solar energy utilization as Thermal Energy Storage (TES) enables electricity generation independently o…
Evaluation of onboard sensors for track geometry monitoring against conventional track recording measurements
Hengcheng Zhang, Zhan Yie Chin, Pietro Borghesani +2
The main objective of this paper is to assess the estimation of track condition parameters using onboard micro-electro-mechanical-system (MEMS) accelerometers. A prototype of an on…
Bayesian Multivariate Track Geometry Degradation Modelling and its use in Condition-Based Inspection
Huy Truong-Ba, Sinda Rebello, Michael E. Cholette +2
Effective maintenance of railway infrastructure is crucial for safe and comfortable transportation. Among the various degradation modes, track geometry deformation due to repeated…
Heliostat-field soiling predictions and cleaning resource optimization for solar tower plants
Cody B. Anderson, Giovanni Picotti, Michael E. Cholette +3
This paper presents a novel methodology for characterizing soiling losses through experimental measurements. Soiling predictions were obtained by calibrating a soiling model based…
Stochastic Soiling Loss Models for Heliostats in Concentrating Solar Power Plants
Giovanni Picotti, Michael E. Cholette, Cody B. Anderson +2
Reflectance losses on solar mirrors due to soiling are a significant challenge for Concentrating Solar Power (CSP) plants. Soiling losses can vary significantly from site to site -…
