We conduct a comparative study to evaluate several lattice Boltzmann (LB) models for solving the near incompressible Navier-Stokes equations, including equation with multiple-relaxation-time (MRT), two-relaxation-time (TRT), single-relaxation-time (SRT) collision models, and entropic (ELBE). The lid-driven square cavity flow in two dimensions is used as benchmark test. Our results demonstrate that ELBE does not improve numerical stability of SRT or Bhatnagar-Gross-Krook (LBGK) model. also...
Pine wood nematode disease has harmed forests in several countries, and can be reduced by locating clearing infested pine trees from forests. The target detection model of deep learning was utilized to monitor a nematode-infested wood. detecting effect good, but limited low-resolution photos with poor accuracy speed. Our work presents staged classification approach for dead based using You Only Look Once version 4 (YOLO v4) Google Inception 1 Net (GoogLeNet), employing high-resolution images...
The Da-Xiao Liangshan Mountains serve as a crucial ecological barrier in the upper reaches of Yangtze River China. This study uses high-precision land use and cover data from 1980 to 2020, applying kernel density analysis, topographic gradient classification, PLUS model, landscape pattern indices, standard deviational ellipse theory analyze spatio-temporal changes, differentiation, fragmentation, driving factors forest area. results reveal following: (1) From was one dominant types area,...

This study utilizes finite element method (FEM) simulate ballistic response B<sub>4</sub>C/UHMWPE targets against 7.62 mm steel-core projectiles, and systematically investigates influence ceramic-to-backing thickness ratio (<italic>R</italic><sub><italic>th</italic></sub>: 0.4-2.0) on under varying areal...
The dynamic monitoring of forest resources is an integral component resource management and eco-system stability maintenance. In recent years, LiDAR (Light Detection Ranging) has been increasingly utilized in precision surveys due to its great penetrating ability capacity detect vertical structure information. However, the present airborne data individual tree segmentation algorithms are not highly adaptable types, particularly mixed coniferous broad-leaved zones, where accuracy extraction...
When calculating the seismic response of structures, conventional methods often neglect uncertainty and suffer from excessive computation. Although robustness metrics have been effective in evaluating structural safety, they are not suitable for isolated continuous girder bridges (ICGB). To address this issue, paper introduces an uncertain assessment method tailored to ICGB: Firstly, considers material parameters ground motion by constructing a data set using Monte Carlo simulation....
We describe an efficient method for positioning a vehicle in noisy environment including malicious attackers and measurement errors. assume the majority vehicles are honest report detection of position other to provide integrity vehicular ad hoc network (VANET). The noise input includes bogus information with errors VANET. Given such input, algorithm estimates high resolution location by filtering refining low input. Moreover, efficiency is highlighted because dynamic characteristic...
In order to investigate the noise impacts of wind turbines with a high single-machine capacity (2 MW) on residents living around, face-to-face questionnaire survey was conducted. The moderating factors annoyance, exposure–response relationships as well sleep and self-reported health were investigated. Results showed that sensitivity, attitude towards turbines’ visual impact landscape, general opinion intensity had statistically significant annoyance due turbine noise. Compared lower in...
Tree growth in power line corridors poses a threat to lines and requires regular inspections.

Abstract Dry lithography is a promising micro-/nanomanufacturing method owing to its advantages of being solution-free, absence undercut and resistance swelling. However, heat-mode resists suitable for dry are less reported. This work reports on the use Ag-doped Sb 2 Te thin film as resist, etching selectivity microstructures investigated in detail. It found that Ag 1.44 2.19 possesses high CHF 3 /O mixed gases can act resist. In order elucidate mechanism selectivity, films analyzed using...
