This paper proposes a prediction strategy for the hydrodynamic performance of bionic fish. The major challenges are meshing and building model. NACA0012 airfoil is used to replace fish driven by body and/or caudal fin (BCF), two-dimensional swimming geometric model constructed. divided into hybrid meshes using overset mesh method. classical traveling wave studied Matlab, an improved self-propelled motion established. numerically simulated based on computational fluid dynamics (CFD). In this...
An enantioselective, copper-catalyzed alkynylation of cyclic α,α-diaryl ketiminium ions has been developed to deliver isoquinoline products with diaryl, tetrasubstituted stereocenters. The success this reaction relied on identification Ph-PyBox as the optimal ligand, i-Pr2NEt base, and CHCl3 solvent. A broad scope functional group tolerance were observed. Notably, use both aryl silyl acetylenes results in high yields enantioselectivities. Mechanistic experiments are consistent a dimeric or...
In this work, we use femtosecond laser direct writing to fabricate two kinds of modified structures with opposite refractive index changes build new dual-line waveguide configurations in z-cut LiNbO3 (LN) crystals for the first time. These hybrid-structure waveguides, which type-Ⅰ modifications are induced between type-Ⅱ tracks have been investigated by an end-face coupling system at 532 nm. The results indicate that TEM00 mode is only transmission all waveguides. Comparing...
The recognition of multiple Autonomous Underwater Vehicles (AUVs) equipped with Side-Scan Sonar (SSS) is the key to marine surveys, and autonomously efficiently recognizing targets an urgent open challenge. This paper proposes a lightweight Recurrent Transfer-Adaptive Learning (RTAL) improve accuracy SSS images. In this work, (1) we analyze target features collected by AUVs, calculate similarity between using Mahalanobis distance, establish threshold. (2) When threshold higher than...
Abstract Slotted reinforced concrete (RC) wall exhibited satisfactory seismic damage reduction performance and rapid rehabilitation. However, the optimal design of slotted RC wall, i.e. section division strength stiffness shear links have not been derived. A numerical model is developed in ABAQUS, which was verified with physical test results. Based on calibrated model, parametric analysis carried out to investigate influence links. The analytical results indicated a non-uniform division,...
A novel idea of anti-interference via solid dilution driven by spontaneous surface dispersion (SSD) is herewith first rendered for elemental analysis to determine trace cadmium in a sample, which similar the monolayer theory originally applied heterogeneous catalysts at percentage level.After pre-ashing with agitation, Cd sample can be efficiently and quickly diluted SSD on α-Al2O3 support heating 600-700 °C 30-40 min, thus leading >180-fold dilution.Secondary ion mass spectrometry (SIMS)...
Abstract In this work, we used femtosecond‐laser direct writing to fabricate two kinds of modified structures with opposite refractive‐index changes build fork‐grating configurations in z‐cut LiNbO 3 (LN) crystals. Experimental and simulation results indicate that the fork grating combined area refractive index increased decreased produces a more effective diffraction effect at 532 nm. The these gratings have been investigated. Compared only refractive‐index‐decreased filaments, when...
Abstract Taking the AU5-50 propeller as an example, detailed process of modeling with atlas method and PropCad is compared. By comparing auxiliary profiles used for modeling, it pointed out that blade model established by has more complete features not restricted type. Besides, to verify credibility method, simulation analysis carried out. First, hybrid mesh boundary layer are divide flow field integrated computer engineering manufacturing (ICEM). Second, grid independence verified utilizing...
