The ability to accurately classify fault type within traveling wave data is crucial for real-time online location and protection using technology. However, the current common practice in power industry relies on manual screening followed by offline processing, leading several limitations such as poor timeliness, low accuracy, high skill requirements operators. These drawbacks restrict application of acquisition devices. To address these issues, this paper proposes a identification method...
Interbody fusion is recognized as the golden standard of surgical intervention for degenerative disc disease (DDD). cage made polyetheretherketone (PEEK) commonly used in lumbar interbody surgery treatment DDD worldwide. However, there are some limitations PEEK including their bio-inert nature and impediment to host bone integration. This study aimed evaluate degradation profile osteoinductive potential biodegradable Mg-Zn-Nd-Zr cages with/without micro-arc oxidation (MAO) coatings. The...
Au/Pd octopods were synthesized with enhanced sample homogeneity through the use of aromatic additives. This increase in monodispersity facilitates large-area periodic assembly stellated metal nanostructures for first time. The additives also found to influence structures nanocrystals subtle shape modifications observed that can alter packing arrangement octopods. These results indicate possibility tailored nanostructures, which would be useful optical applications require strong and...
In this article, we proposed a see-through three-dimensional (3D) signage system that can be observed on both sides. It comprises two parts: light emitting diode source and an edge-lit waveguide embossed with pixelated metagratings. Two sets of sparsely distributed metagrating matrices were carefully designed to reconstruct dual-color 3D virtual scene while maintaining high transparency. The transparency the was above 70%, complex wavelet structural similarity value 0.93, suggesting image...
The distribution network fault will cause big range and long-time blackout which affect the safe stable operation of power system. difficulty locating grounding faults in networks is arc-suppression-coil-ground neutral introduction arc suppression coil increase compensation current system make relationship among zero sequence currents more complex, moreover, comparison to realize location becomes difficult. Although residual increment method, short-circuit indicator signal injection method...
In this paper, a kind of transparent 3D static display consisting flat glass waveguide and single layer gratings is proposed. The are shaped into various patterns designed pixel by to provide correct parallax images. Incident light from the edge can only be extracted patterned area projected views. prototype shows advantage wide field view (60°), small angular separation (5°) high transmission (<60%). Virtual objects blend well with real scene. Potential applications include window advertisements
In large power generation enterprises with extensive land coverage and diverse equipment, traditional Electric Motor (EM) condition monitoring methods result in high labor costs heavy workloads for field inspection personnel. This paper proposes a method using Deep Learning (DL) fault diagnosis of EM bearings displays the information on frontend web page through Unity WebGL application. Firstly, Wide Convolutional Neural Network (WDCNN) model is employed to pre-train perform classification...
Abstract The resonant Raman spectroscopy can only detect on‐resonance single‐walled carbon nanotubes (SWNTs) within the laser resonance window. In principle, surface‐enhanced scattering (SERS) expand However, detection of off‐resonance SWNTs by SERS remains challenging due to difficulties in locating exactly at hot spots with enormous enhancements. Here, polyhedral gold nanocrystals (AuNCs) are situ prepared on for via a facile ultrasonic spray pyrolysis method. fact that edges AuNCs attach...

Aiming at the non-stationary and nonlinear characteristics of tool wear signal in cutting process problem that it is difficult to effectively identify state, a state recognition method based on feature fusion fuzzy neural network proposed Multi-domain features were extracted from frequency domain time-frequency domain, then several with higher information selected according pearson correlation coefficient. Then, optimal set was obtained by using PCA algorithm. Finally, multi-dimensional are...
SnSe is a promising thermoelectric material because of its intrinsic low lattice thermal conductivity. However, the inferior electrical transport properties restricted performance n-type polycrystals especially at lower temperature range. In this work, an effective strategy to enhance by CeCl3 doping reported. increased both carrier concentration and mass. The high weighted mobility contributed power factor over whole Combined with reduced conductivity, peak zT ~1.3 823 K was obtained in...
Multi-Robot Cooperative Localization (MRCL) is a promising technology for applications, e.g., shipping, production, logistics, etc. However, MRCL outdoor applications faces challenges in localization accuracy due to the low-precision baseline measurement between every two robots by Global Positioning System (GPS).
