A high-efficiency rectifier designed to operate across a broad range of frequencies and power levels is proposed in this letter. The features dual-branch impedance regulation network (IRN), two subrectifiers, load resistor. IRN used construct specific relationship between the upper lower branches at different levels, demonstrating good matching performance wide bandwidth dynamic (DPR). Theoretical analysis carried out, prototype implemented, fabricated, measured for verification. At 1.8 GHz,...
This study explored the protective effects of antifreeze glycopeptide and alginate on quality −18 °C frozen lamb meatballs across various storage periods. Methods: Measurements volatile salt nitrogen (TVB-N), thiobarbituric acid (TBARS), water retention, distribution, microstructure, metabolite changes were taken in meatballs.

Because of the relatively low accuracy current asphalt pavement performance prediction, a new prediction model was established based on particle swarm optimization (PSO) algorithm and support vector machine regression (SVR) algorithm. First, SVR introduced into to deal with nonlinear regression. Then PSO applied improve searching efficiency parameter continuity The inspection data an expressway in eastern China from 2006 2015 were used verify results, proving feasibility PSO-SVR model....
Micro-ejecta, an instability growth process, occurs at metal/vacuum or metal/gas interface when compressed shock wave releases from the free surface that contains defects. We present molecular dynamics (MD) simulations to investigate ejecta production tin shocked by supported and unsupported waves with pressures ranging 8.5 60.8 GPa. It is found loading waveforms have little effect on spike velocity while remarkably affect bubble velocity. The of remains nonzero constant value late time as...
The spatiotemporal characterization of unknown sources groundwater pollution is frequently encountered in environmental problems. This study adopts a simulation–optimization approach that combines contaminant transport simulation model with heuristic harmony search algorithm to identify sources. In the proposed methodology, an almost-parameter-free developed. performance this methodology evaluated on illustrative source identification problem, and identified results indicate algorithm-based...
A sound–structure interaction model is established to study the vibroacoustic characteristics of a semisubmerged cylindrical shell using wave propagation approach (WPA). The fluid free surface effect taken into account by satisfying sound pressure release condition. Then, far-field predicted with shell's vibration response stationary phase method. Modal coupling arises due presence surface. New approaches are proposed handle this problem, i.e., diagonal acoustic radiation (DCARM) and column...

ABSTRACT This study investigates, for the first time ever, suffusion on gap‐graded granular soils under torsional shear conditions from a microscopic perspective. A numerical model of hollow cylinder test (HCTST) using discrete element method (DEM) is developed, where an algorithm simulating real inner and outer rubber membranes apparatus (HCA) introduced. After validation, computational fluid dynamics (CFD) approach introduced coupling between particle phases. Then, series coupled CFD‐DEM...
As the common technique used in monitoring system, Motion Detection Technology generally conducts tracking by finding motion trace of targets through analysis video frame sequence, however, high efficiency and validity target pattern matching can not be guaranteed. By means characteristics Gaussian distribution scaling density functions, this paper has studied designed a kind algorithm for detecting moving target, which realize foreground detection on achieve background update model updating...
For obtaining pure phase Tl2Ba2Ca2Cu3O10 (Tl-2223) films with good superconducting properties, the growth technique is improved by dc magnetron sputtering and a triple post-annealing process. The process comprises annealing twice in argon once oxygen at different temperatures. In first low-temperature argon, Tl2Ba2CaCu2O8 (Tl-2212) obtained to effectively minimize evaporation next step. With increase of temperature second stage previously prepared Tl-2212 inter-phase converted into Tl-2223...

Abstract Numerical investigation of the underexpanded sonic coaxial jets is carried out using large eddy simulation for three typical inner nozzle lip-thicknesses. Various fundamental mechanisms dictating flow phenomena including shock structure, shear layer evolution and sound production are investigated. It found that lip induces a recirculation zone between outer jets, which significantly influences behaviors structures layers. The properties further analyzed in detail. As lip-thickness...
