Analysis of Casing Loads in Coalbed Methane Horizontal Wells during Multi-Stage Hydraulic Fracturing

This study develops a high-precision, composite induced-stress prediction model for deep coalbed methane horizontal wells in the Ordos Basin by integrating a 3D geomechanical model with a modified analytical approach optimized via the sparrow search algorithm, ultimately providing a validated framework for optimizing fracturing parameters and ensuring casing integrity during multi-stage hydraulic fracturing.

Flow-field simulation and experimental validation of ultrasonic-assisted abrasive water flow polishing for additively manufactured high-aspect-ratio internal channels

This study demonstrates that ultrasonic-assisted bidirectional abrasive water flow polishing significantly enhances the surface quality, machining uniformity, and processing efficiency of additively manufactured high-aspect-ratio internal channels by leveraging cavitation-induced micro-jets to effectively finish difficult-to-reach corner regions.

Equilibrium Analysis and Gyro-Stabilization of Two-Wheel Inverted Pendulum Robot on Inclined Surfaces

This study presents a nonlinear dynamic model and a dual-loop control strategy for a two-wheel inverted pendulum robot equipped with a scissor-pair control moment gyroscope, demonstrating its ability to maintain equilibrium and navigate inclined surfaces by leveraging gyroscopic torque to counteract gravitational forces at a specific tilt angle.

Path-resolved melt-track width enables relative spatial-stability characterization and velocity–orientation mapping in laser powder bed fusion

This paper introduces a path-resolved melt-track width analysis and a composite spatial-stability index (Sspatial) for laser powder bed fusion, demonstrating that while this approach effectively characterizes local fluctuations and ranks stability under fixed conditions, it faces significant challenges in extrapolating to new scan orientations.

Modelling and simulation study on dynamic pollution accumulation process of disc insulator

This paper presents a validated two-stage dynamic deposition model for disc insulators that integrates multi-physics trajectory analysis with a neck-height-based contact mechanics criterion to reveal how wind speed, particle size, and electric field polarity influence pollution accumulation.

Development and Laboratory Assessment of a Small Torsional Direct Shear Test Apparatus

This paper presents the development and laboratory validation of a compact Torsional Direct Shear Test (TDST) apparatus retrofitted onto a conventional frame, demonstrating that while a 90 mm vane effectively characterizes natural soils and high-clay mixtures with conservative results, a 60 mm vane proves unstable and inaccurate for high-clay contents, thereby establishing the device as a critical laboratory precursor for future field-scale validation.

Disruption-aware reserve-constrained dispatching of battery-electric AGVs for brownfield manufacturing intralogistics

This study introduces a disruption-aware reserve-constrained dispatching (RCRD) rule for battery-electric AGVs in brownfield factories that screens assignments for charger reachability and ranks them using multiple operational factors, demonstrating a statistically significant reduction in mean tardiness compared to energy-aware baselines, particularly under conditions of simultaneous demand and route stress.
