This work addresses the challenge of maintaining safe operation of Class 8 heavy-duty vehicles under dynamically varying physical, environmental, and human conditions. Current vehicle safety systems and powertrain controls are largely reactive or rule-based, relying on fixed thresholds, static margins, or post-event interventions. While effective in limited domains, these approaches do not explicitly account for
The invention provides a dynamic framework for continuously estimating and managing the operational safety state of autonomous and highly automated commercial vehicles throughout their service life. Unlike conventional safety assurance approaches that rely primarily on static certification, periodic inspections, or qualitative safety case documentation, the proposed framework maintains a continuously evolving quantitative representation of operational
A single-switch based low power, medium voltage isolation level, wide voltage range, soft switching power supply design procedure and implementation, utilizing a PCB based coreless transformer and inductors to achieve high inter-winding isolation, low common-mode capacitance, and compactness.
Provides a method to operate an engine using the Gane combustion strategy at or near stoichiometric air/fuel ratios. The idea is to operate an engine using the Gane combustion strategy at or near stoichiometric air/fuel ratios. This is possible due to the low AFR requirement of DME and methanol as oxygenated fuels, and the fact
The rising supply-chain vulnerability of natural graphite requires imminent transcendence to cost-effective and sustainable synthesis of artificial graphite, as well as disentanglement from the energy-intensive and time-consuming Acheson process, used to graphitize non-renewable petroleum coke at 3000 degrees C. An emerging method proven able to satisfy these demands involves the cathodic polarization of carbons in
Implementation of WPT for UAV applications has been challenging due to the limited space for the receiver coil and the misalignments that occur because of the landing imperfection. In this study, a novel magnetic coupler structure proposed to increase the misalignment tolerance with a compact and high-efficiency system.
This work proposes data-driven control via a nonlinear autoregressive model with exogenous inputs (NARX) for real-time voltage regulation of a modified feeder using reactive power sources. Traditional voltage control strategies rely on rule-based heuristics or optimization techniques, which often require detailed system models and extensive computational resources. The NARX-based controller learns system dynamics from historical
This concept introduces a method to evaluate vehicle safety performance by quantifying the degree of risk associated with near-miss events—situations where a collision is narrowly avoided. The approach is designed to serve as a leading indicator of safety for advanced vehicle systems operating in commercial freight environments. It considers vehicle motion, system response timing, and
Amine-based carbon capture is well established for both point-source and direct air capture applications, but the energy needed for regeneration of CO2-loaded solvents can limit broader deployment. ORNL’s technology integrates catalytic functionality directly into structured or random packing used in solvent-regeneration equipment. By enabling catalytic activity within a form compatible with conventional regeneration columns, the
This invention discloses a developed two-dimensional catalyst for efficient, selective and stable hydrogenation of CO2 to CO at temperatures as high as 600 degrees C. The bare catalyst shows high activity at temperatures as low as 400 degrees C and reaches equilibrium conversion above 550C with close to ~100% selectivity to CO. The CO production
Cold-weather defrost cycles can reduce air-source heat pump efficiency and compromise indoor comfort, particularly when conventional systems reverse operation or rely on electric resistance heating. This technology integrates thermal energy storage with an air-source heat pump to provide a dedicated thermal energy source during defrost cycles, helping maintain conditioned-space comfort while reducing auxiliary electric heating
