This study proposes an alternative and competitive methodology for predicting solitary wave forces on coastal bridge decks using artificial neural networks (ANNs). It is imperative to accurately predict the on-deck design retrofit of bridges subject potential impact hurricanes tsunamis. For this purpose, ANNs are used determine loads based a valid data set. First, structural, fluid, variables involved in deck-wave interaction briefly introduced. The back-propagation network (BPN) force...
The short-range order (SRO) structure in high-entropy alloys (HEAs) is closely associated with many properties, which can be studied through density functional theory (DFT) calculations. Atomic-scale modeling and calculations require substantial computational resources, machine learning provide rapid estimations of DFT results. To describe SRO information HEAs, a new descriptor based on Voronoi Analysis Shannon Entropy (VASE) proposed. Based analysis, the entropy introduced to directly...
The relative degradation in time of the visible(channel 1: 0.58-0.68jim) and nearinfrared(channel 2: 0.72-1.lpm) channels Advanced Very High Resolution Radiometer(AVHRR), onboard NOAA polar-orbiting operational environmental satellites(POES), has been determined, usi.ng southeastern Libyan desert(21-23°N latitude; 2829° E longitude) as a time-invariant calibration target. A statistical procedure was used on reflectance data for two from B3 International Satellite Cloud Climatology...
Subtropical evergreen broad-leaved forest (EBLF) is the zonal vegetation of Chinese subtropical region, among which most typical and widely distributed type mid-subtropical EBLF.To explore how 2008 ice-storm affected short-term dynamics EBLF, we examined community structure species composition pre post ice storm 24 ha plot in Gutianshan.We found that although DBH size class was highly consistent storm, level recruitment low mortality high.Results analyses conducted at various grain scales...
In this paper, a new fast and efficient algorithm, Chebyshev super spectral viscosity (SSV) method, is introduced to solve the water hammer equations. Compared with standard method's advantage essentially consists in adding equations for high wave numbers of numerical solution. It can stabilize oscillation (Gibbs phenomenon) improve computational efficiency while discontinuities appear Results obtained from method exhibit greater consistency conventional calculations. shows that offers an...
The observed in-orbit degradation in the performance of visible (channel 1: /spl ap/0.58-0.68 mu/m) and near-infrared 2: ap/0.72-1.1 channels Advanced Very High Resolution Radiometer (AVHRR) on board NOAA Polar-orbiting Operational Environmental Satellites has been estimated, using vicarious calibrations over southeastern Libyan desert (21/spl deg/-23/spl deg/N; 28/spl deg/-29/spl deg/E) which was assumed to be a radiometrically stable calibration target. annual relative rates, per cent, for...
Tantalum nitrides (TaN) have attracted much attention as a new material of energy exchangers in insensitive detonators, we mainly investigate its ignition law this paper. Firstly, the paper utilizes numerical simulation to predict influence substrate material, bridge zone thickness, length and width on action. Then reliability was verified by experiments, which provided technical support for design passivated pyrotechnics.
The rainbow like color of butterfly wings is associated with the internal and surface structures wing scales. While photonic structure scales believed to diffract specific lights at different angle, there no adequate probe directly answering 3‐D sufficient spatial resolution. NSRRC nano‐transmission x‐ray microscope (nTXM) tens nanometers resolution able image biological specimens without artifacts usually introduced in sophisticated sample staining processes. With intrinsic deep penetration...

FLAC3D using numerical simulation method analyze section coal pillar width in 20 m, 10 when 0 Face sequential mining process key strata caving stride, instability from damage induced rock burst dangerous. The results showed that: (1) reasonable pillars can effectively reduce occurrence burst; (2) composite layer destruction and is main occurred.
Without modification or a small wheeled vehicles converted premise modular rubber track system can be direct replacement tire vehicles, so that it becomes tracked thus increasing its off-road performance.Frame as key component of the system, supporting all other structures system.According to frame form and assembly mode vehicle,the divided into two kinds integral type separated type.The design, finite element analysis verify uniform stress concentrated is less than allowable stress.
