This study utilizes non-Newtonian CFD modeling to demonstrate that while increasing impeller rotation rates significantly reduces dead zones in a portable anaerobic digester, an operational range of 60–90 rpm offers the optimal balance between mixing performance and energy efficiency.
This paper presents a novel non-contact underwater acoustic source detection paradigm using terahertz radar sensors that leverages surface micromotion physics to overcome sea-air interface barriers, successfully validating a full-chain framework for extracting sub-micrometer signals from strong sea clutter through real-world field experiments at sea state 2.
This study combines experimental push-out tests and three-dimensional nonlinear finite element analysis to investigate the time-dependent shear deformation mechanism of headed stud connections in steel-concrete hybrid girders under sustained loading, revealing that creep-induced shear force redistribution drives long-term slip and demonstrating that limiting sustained shear force levels effectively mitigates such deflection.
This paper demonstrates that the Phototropic Growth Algorithm (PGA) effectively solves the non-convex, single-objective economic and environmental dispatch problems for a 40-unit thermal power system with valve-point effects, outperforming recent metaheuristics in convergence stability, solution quality, and execution time.
This paper analyzes the outage performance of a NOMA-assisted UAV-ambient backscatter communication network with hardware impairments, deriving analytical expressions for outage probability and ergodic capacity under perfect and imperfect successive interference cancellation to demonstrate that the proposed scheme significantly outperforms benchmarks, particularly when using maximum ratio combining and optimizing reflection coefficients.
This paper presents a passive, Genetic Algorithm-optimized L-match network that overcomes the efficiency limitations of deep sub-threshold RF energy harvesting by dynamically tracking diode impedance across a 20 dB power range, achieving over 90% transmission efficiency without the power overhead of active tuning circuits.
This study demonstrates that a non-autonomous aerial photogrammetric approach using manually captured images at combined 45° and 60° viewing angles can significantly reduce data volume and flight time while achieving highly precise 3D reconstructions with volume calculation errors of less than 0.5%.
This study demonstrates that ultrasonic desalination of sea sand effectively meets recycled aggregate standards across a wide range of water temperatures without active heating, with ambient conditions (~25°C) offering the most stable and efficient performance compared to low or elevated temperatures.
This paper presents a novel multi-objective optimization strategy combining an enhanced Analytical Permeance Unit model, a hybrid irregular-teeth/asymmetrical rotor topology, and robustness validation to significantly improve torque density and reduce ripple in multi-harmonic IPM Vernier machines, as demonstrated by a prototype achieving 26.8 kNm/m³ torque density and 4.7% torque ripple.
This study demonstrates that combining foam-filling with an optimized elliptical re-entrant metamaterial architecture significantly enhances specific energy absorption and crushing stability under quasi-static compression, increasing performance from 20.05 J/kg to 406.23 J/kg while suppressing deformation localization.
