The fatigue damage of steel bridges induced by heavy traffic loads is a critical problem worldwide. A uniform vehicle generally adopted in bridge design codes to evaluate the cumulative bridges. However, since vary across sites, single with predetermined parameters may be imprecise for actual estimations. In this study, new method developing models that are applicable various conditions proposed. China was taken as an example illustrating proposed method. Numerical simulations were performed...
X-ray absorption near-edge structure (XANES) spectroscopy is used to study the features of occupation sites Mn dopants in Ga1−xMnxN dilute magnetic semiconductors (DMSs) with zinc-blende structure. Theoretical XANES spectra are calculated for representative models atoms GaN lattice. It shown that substitutional characterized by a preedge peak at 2.0eV and postedge multiple-scattering 29.1eV. The peaks shift position drop intensity dramatically interstitial MnI MnGa–MnI dimer, then disappear...
Abstract The adverse effects of a sprinkler on smoke exhaust systems used to be debated in designing fire safety provisions. However, very few experimental studies the interaction with layer have been reported; therefore, this study investigates and reports water spray by specially designed rig 25 tests. Smoke spreading from chamber was collected an adjacent hall. stability then studied discharged spray. ratio drag buoyancy is proposed determine stability.
Temperature detection is particularly important in the medical and scientific fields. Although there are various temperature methods, most of them focus on broad detection, basic research specific fields, especially subtle changes (32-34 °C) during wound infection, still insufficient. For this purpose, a novel colorimetric sensing probe designed paper, which can quickly intuitively respond to small within range through color changes. In hyperbranched polyethyleneimine (HPEI) was modified by...
First-principles calculations were performed to study the electronic structure and magnetic interactions of ${\mathrm{Mn}}_{\mathrm{Ga}}\text{\ensuremath{-}}{\mathrm{Mn}}_{\mathrm{I}}$ dimer formed by neighboring substitutional ${\mathrm{Mn}}_{\mathrm{Ga}}$ interstitial ${\mathrm{Mn}}_{\mathrm{I}}$ ions in zinc-blende structured $(\mathrm{Ga},\mathrm{Mn})\mathrm{N}$ dilute semiconductor. On basis formation energy calculations, we show that clustering is energetically favored. The are...
In this study, porous Cu-doped NiFe-LDH nanosheets were synthesized through a cation exchange method, and exhibited highly competitive OER catalytic activity stability.
ABSTRACT A novel gel of imidazole/(HPO 3 ) was synthesized and incorporated into sulfonated poly (ether ether ketone) (SPEEK) to fabricate composite proton exchange membranes. The membranes were characterized by alternating current impedance (AC), thermogravimetry (TG), differential scanning calorimetry (DSC), X‐ray diffraction (XRD), electron microscope (SEM) mechanical property test. Based on the electrochemical performance investigation, conductivity membrane is intimately correlated with...
We report a new TFT short‐wave infrared (SWIR) sensor based on colloidal quantum dot (CQD) technology. As the name suggests, its function is to detect and image band. This an industry‐leading SWIR sensor. The active layer made of material, detection band 0.9~2.5um. dots are interconnected with reading circuit through spin coating, spraying, screen printing or scraping. gets rid limitation indium column flip‐chip bonding process traditional gallium arsenide CMOS focal plane sensor,...
For a given $n$, what is the smallest number $k$ such that every sequence of length $n$ determined by multiset all its $k$-subsequences? This called $k$-deck problem for reconstruction, and has been generalized to two-dimensional case -- reconstruction $n\times n$-matrices from submatrices. Previous works show at most $O(n^\frac{1}{2})$ sequences $O(n^\frac{2}{3})$ matrices. We study this general dimension $d$ prove that, $O(n^\frac{d}{d+1})$ reconstructing dimensional hypermatrix order...
Phase unwrapping (PU) is one of the core procedures interferometric synthetic aperture radar (InSAR). The traditional phase methods estimate absolute gradient based on assumption that spatially continuous. However, this often not true due to large gradient. In paper, a local enhanced U-net (LEU-Net) was developed determine discontinuity SAR differential interferograms in areas with substantial elevation change. predicted by network used as priori information for maximum flow\minimum cut...
Quantum dots have been rapidly developed in the display field, especially as photoluminescent color conversion layers. At same time, quantum also made increasing research progress detection field. We reported a short‐wave infrared sensor based on colloidal dot technology. The photosensitive layer of uses HgTe material. band is 0.9~1.7um, resolution 1280*1024, and pixel pitch 15um.

A high-strength Al-Mg-Si alloy was prepared using mechanical alloying (MA) combined with press-forming (PF) technology, achieving a strength of up to 715 MPa and hardness 173 HB. The microstructures were comparatively analyzed conventional cast alloys XRD, TKD, TEM. XRD results showed that the full width at half maximum (FWHM) by MA+PF significantly broadened accompanied shift in diffraction peak. TKD revealed grain size processed reduced approximately 260 nm, indicating substantial...
