Electric current pulse (ECP) was commonly applied to solidification process of Al melt achieve fine microstructure. In this paper, numerical simulation method employed analyse flow behaviour the and mechanism ECP on grain refinement during solidification. The calculation results showed that led fluctuation liquid surface, flowed inward down in a circular motion. were caused by forces including Lorentz force, surface tension buoyancy. also revealed higher frequency peak value ECP, larger...
In order to solve the problems including poor signal denoising effect, low recognition rate, and real-time performance in wire rope magnetic flux leakage (MFL) testing, this paper proposes a new algorithm combining kernel extreme learning machine (KELM) with compressed sensing wavelet (CSW). F irstly, we consider mechanism regularized orthogonal matching pursuit (ROMP) into CSW, combine double-density transform (DD-DWT) improve result of noise reduction; Then, an effective normalization...
The lifetime of wire rope is crucial in industry manufacturing, mining, and so on. damage can be detected by using appropriate nondestructive testing techniques or destructive tests cutting the part. For broken wires classification problems, this work aimed at improving recognition accuracy. Facing defects exterior rope, a novel method for firstly developed based on magnetic infrared information fusion. A denoising method, which adopted signal, proposed eliminating baseline signal wave...
Whether the regression of gastric metaplasia in duodenum can be achieved after eradication Helicobacter pylori is not clear. The aim present study was to investigate relationship between H. infection and patients with endoscopic diffuse nodular duodenitis. Eighty-six endoscopically confirmed duodenitis 40 control normal duodenal appearance were investigated. pylori-positive received anti-H. triple therapy (20 mg omeprazole plus 250 clarithromycin 400 metronidazole, all twice daily) for one...
The friction pair wear in a high-pressure vane pump caused by solid particles oil is significant factor that affects the pump's service life. study investigates effects of on tribological characteristics valve plate pump. varying particle diameters (5–20 μm) and concentrations (0.001–0.015%) coefficient, rate, surface morphology were investigated. In addition, to effect diameter concentration volumetric efficiency, efficiency was tested. According results, when 0.001%, coefficient increased...
To control high speed underwater vehicles, a proximity ranging system is needed to monitor the cavity thickness. In this paper, we study time-of-flight (TOF) principle based acoustic system. By taking into account acoustically hard boundary at air-water interface, first present two-stage computationally efficient time delay estimation algorithm, referred as PEARS (Parameter Estimation for Acoustic Ranging Systems) which applicable arbitrary transmitted waveforms. Numerical results on...
Subway train's collector shoes obtain electric energy from the power supply system, and sliding contact between third rail could cause wear, which has a significant influence on safety of train. Besides, wear intensity is related to multiple factors. This paper presents method based train operating mileage, makes prediction current degree tests effectiveness this according experiment.

The k-means algorithm was used to divide the acoustic emission signals collected during three-point bending test into two types. Combining with analysis of AE parameters can we distinguish micro-damage pattern recognition refractory materials. equipment is HMOR/STRAIN, and acquisition device DISP from PAC. Amplitude, counts, risetime, duration centroid frequency were selected as .The microscopic damage modes materials recognized.
With the continuous improvement of level science and technology, conventional substations have basically realized digitization intelligence inspections, photovoltaic power stations need to be at forefront development. At present, there are still some plants that not yet gotten rid shackles traditional inspection mode, which restricts development plants. Therefore, in order promote intelligent process plants, a targeted robot overall framework was designed, including integrated functions such...
