SUMMARY For second‐order problems, where the behavior is described by partial differential equations, numerical manifold method (NMM) has gained great success. Because of difficulties in construction H 2 ‐regular Lagrangian partition unity subordinate to finite element cover; however, few applications NMM have been found fourth‐order problems such as Kirchhoff's thin plate problems. Parallel methods, this study constructs space Hermitian form solve From minimum potential principle,...
The 22 May 2021 MW 7.4 Madoi, Qinghai, China earthquake presented a rare opportunity to apply the modern unmanned aerial vehicle (UAV) photography method in extreme altitude and weather conditions image surface ruptures near-field effects of earthquake-related deformations remote Tibet. High-resolution photographs were acquired days immediately following mainshock. complex rupture patterns associated with this event covered comprehensively at 3–6 cm resolution. This effort represents first...
This study investigates the effects of aged asphalt binder content, rejuvenators, and warm mix agents on adhesive properties, micro-morphological evolution, chemical compositions binder. Employing Surface Free Energy (SFE), Atomic Force Microscopy (AFM), Fourier-Transform Infrared Spectroscopy (FTIR), Gel Permeation Chromatography (GPC) provided a comprehensive understanding. Aged reveals alterations in its microstructure components, influencing adhesion capabilities. Rejuvenators counteract...
Abstract A simplified model using a modified effectiveness–Number of Transfer Units (NTU) method for thermal performance simulation indirect evaporative heat exchangers is presented and then validated utilizing experimental data from the literature. The objective this to facilitate efficient computer cooling or hybrid cooling/direct expansion vapor compression systems, both which include an exchanger as core component. Through some approximations, governing differential equations that...
Dendrimer-like mesoporous silica nanoparticles (MSNs) with large center-radial mesopores have been prepared for macromolecular protein loading and delivery.
Abstract Rock classification is critical in geological research and geoscience applications. Traditional methods rely heavily on manual expertise, which makes them susceptible to human errors due their reliance individual skills experience. Although current machine learning models have mitigated some drawbacks by classifying rock images, generalization predictive performance are limited suboptimal network structures, image data quality, quantity. These also require feature extraction,...
Abstract Background Screen time and physical activity behaviors undergo development during early childhood impact mental health. However, there is limited knowledge regarding the associations between activity, screen time, health problems (MHP) in preschoolers. This study examines these using a large sample size brief measures. Methods A multistage cluster stratified sampling method was used to conduct an observational cross-sectional of 19,015 Chinese preschoolers 2020. Information on...
Ship collision avoidance (SCA) is an important technique in the field of decision-making marine navigation. Although some promising solutions have been developed recently, there still lack low-cost and reliable sensing equipment. Inspired by camera sensors success machine learning, this paper designs a vision-based method to recognize ships their micro-features for SCA navigation planning. Firstly, we develop bearing, distance velocity model based on wide-field optical imaging system....
