Infrastructure-Oriented Assessment of Energy Efficiency and Estimated CO2 Emissions at the Combustion Stage of a Diesel–LNG Dual-Fuel Mining Dump Truck Based on Field Telemetry Data

Haul-road condition can affect traction demand and diesel-to-LNG substitution in mining trucks. We evaluated a 140-t truck at the Ekibastuz coal mine using 180 registered cycles (88 diesel-only [DOM], 92 dual-fuel [DGB]), 24 road segments, 36 defect events and 30 matched fuel-mode pairs. Mean ECM-reported substitution...

Permutation-Centered Henze–Zirkler Screening with Ties: Exact Finite-Sample Centering, Controlled Pairwise Approximation, and Field Assessment

PCHZ-SIS (permutation-centered tie-aware Henze–Zirkler sure independence screening) is a specialized marginal screening method for mixed data containing continuous and ordered–discrete predictors with extensive ties. The method combines tie-aware mid-rank Gaussianization, exact analytical computation of the conditional...

Field-Validated Probabilistic Digital Twin of a Shipboard Microgrid for Reliability-Oriented Operation: Applications to Hybrid and Unmanned Vessels

The transition toward unmanned and hybrid vessels increases the requirements for diagnosability and continuity of power supply to critical consumers under physical and information-layer faults. The aim of this study is to develop a probabilistic digital twin of a shipboard microgrid that combines nonlinear state estima...
