Acoustic rays are modified while propagating through oceanic eddies. However, due to the lack of field synchronous observation, impact mesoscale eddy on acoustic propagation is less clarified. To address issue, an eddy-acoustic observation (EASO) experiment for a warm was carried out in slope South China Sea (SCS) October, 2021. During experiment, total 105 conductivity-temperature-depth (CTD) ...

A well-designed carrier tracking loop in a receiver of the Global Navigation Satellite System (GNSS) is premise accurate positioning and navigation an aircraft-based surveying mapping system. To deal with problems Doppler estimation high-dynamic maneuvers, interest on maximum-likelihood (MLE) increasing among academic community. Levenberg-Marquardt (LM) method usually regarded as effective prom...

At present, Synthetic Aperture Radar Interferometry (InSAR) has been an important technique for active landslides recognition in the geological survey field. However, traditional interpretation method through human–computer interaction highly relies on expert experience, which is time-consuming and subjective. To solve problem, this study designed end-to-end semantic segmentation network, calle...

In this paper dynamic analysis of multi-directional functionally graded panel is studied using a semi-analytical numerical method entitled the state-space based differential method (SSDQM) and comparative behavior modeling by artificial neural network (ANN) for different parameters. A semi-analytical approach which makes use the three-dimensional elastic theory and assuming the material propert...

this article deals with the buckling analysis of perfectly bonded cross-ply laminated composite plates reinforced by wavy carbon nanotubes (cnts) under in-plane loads using element free galerkin (efg) method based on first-order shear deformation theory (fsdt). the wavy single-walled cnts and poly-co-vinylene are used for the fibers and the matrix, respectively. the cnt fibers are distributed i...

INTRODUCTION Accommodative Convergence/Accommodation (AC/A) ratio is constant at one and the same person in the course of life, i.e. the same ratio accommodative convergence monitor any change in accommodation measured in diopters. Such a perfect relationship is possible if there are no refractive anomalies in both eyes and oculomotor imbalance of eye muscles. MATERIAL AND METHODS We are exam...

Chiral α-branched allylic amines are important building blocks for organic synthesis, and several catalytic asymmetric methods have been developed for their synthesis. For example, enantioselective metal-catalyzed amination of allylic electrophiles 1 , 2 , 3 ] and rearrangement of allylic imidates have proven to be highly effective. An alternative approach to chiral allylic amines that can be a...

In this paper, we investigate an intelligent reflecting surface (IRS)-assisted integrated sensing and communication (ISAC) system design in a clutter environment. Assisted by IRS equipped with uniform planar array (UPA), multi-antenna base station (BS) is targeted for simultaneously multiple targets the non-light-of-sight (NLoS) region communicating users (CUs). We consider joint IRS-assisted I...
