This study utilizes CFD analysis to demonstrate that integrating a steam methane reformer with a fixed-bed adsorption unit for blue hydrogen production achieves optimal CO₂ capture and hydrogen purity under conditions of low temperature, high pressure, moderate CO₂ concentration, and low gas hourly space velocity.
This study proposes a robust and interpretable Gradient Boosting Machine (GBM) model, enhanced by SHAP analysis, to accurately predict the uniaxial compressive strength of cemented hydraulic backfill, revealing that cement content and curing time are the most critical factors influencing strength and offering a reliable tool for optimizing mine safety.
This study utilizes a digital twin methodology to overcome the limitations of traditional models, enabling high-fidelity, real-time optimization of turboprop engine pressure ratios across diverse flight conditions to enhance thermal and propulsive efficiency.
This study employs analytical modeling and numerical simulation to quantify the rapid transient heat loss from bare feet to ceramic tiles, revealing that high material effusivity causes immediate skin temperature drops of 4–7°C and peak heat fluxes exceeding 27,000 W/m², thereby establishing a thermo-fluids framework for predicting and mitigating local thermal discomfort in tile-floor designs.
This study evaluates a Shenzhen building portfolio under carbon constraints, demonstrating that while temporal load shifting primarily reduces operating costs, net energy reduction is essential for alleviating binding emissions budgets, thereby supporting the need for distinct market definitions for these two flexibility services.
This paper introduces a zero-setup framework that combines material-agnostic mask preparation with a pretrained semantic segmentation network to enable immediate, high-quality multi-phase segmentation of synchrotron X-ray tomography data without requiring manual thresholding, user prompting, or dataset-specific retraining.
This paper presents a miniaturized 10-GHz microstrip patch antenna utilizing a novel metamaterial-patterned wired defected ground structure that achieves a 72.95% size reduction and 33% bandwidth while maintaining high performance for satellite and radar applications.
This paper proposes an SOP-assisted pilot protection scheme for distribution feeders that utilizes active 300 Hz signature-harmonic injection to reliably discriminate internal and external faults and identify faulted phases, overcoming the limitations of conventional differential protection caused by the soft open point's control characteristics.
This paper proposes a fuel-efficient aeroassisted maneuver strategy for high lift-to-drag ratio spacecraft that achieves significant orbital inclination changes in low Earth orbit by iteratively combining multiple atmospheric passes with constant bank angles and post-exit three-impulse corrections, thereby substantially reducing fuel consumption compared to traditional purely propulsive methods.
This study investigates the impact of build interruptions on Laser Powder Bed Fusion of Nickel alloy 718 and AlSi10Mg using mechanical testing, CT scanning, and in-situ monitoring, finding that while ultimate tensile strength and fatigue life remain largely unaffected, a notable change in pixel intensity averages was observed for IN-718 at the interruption point.
