Aiming at the non-stationary and non-linearity characteristics of vibration signals centrifugal pump, a new method based on complexity feature Empirical Mode Decomposition (EMD) Least Square Support Vector Machine (LS-SVM) is put forward. First all, was used to decompose into finite number stationary Intrinsic Functions (IMF), then features each IMF extracted as fault vectors served input parameters LS-SVM classifier diagnosis fault. Application results showed that proposed very effective,...
Five typical flow patterns are shot in the horizontal pipe test section by high-speed photography technology. Then connected regions of pattern images obtained. The region is different from gray texture. Connectivity characteristics morphological images, no influence light and shade can explore deeply image structural information. To analysis result, standard deviation average five eliminated through combination four kinds coefficient variation statistical two regions. And flowing mechanism...
A new method of nonlinear analysis is proposed by combining the sliced trispectrum with fluctuation characteristics, and influences length time sequence fast Fourier transform (FFT) on characteristic value are discussed. It found that in absence noise, FFT proportional to vector distance value; presence it approximate inversely related. In order test anti-noise ability characterize complexity characteristics method, applied fractal (Brown), chaotic (Lorenz) periodic (sine signal). The...
The characteristics of stability diagram several typical flow patterns are studied, and the signals under 47 kinds flowing conditions identified with stochastic subspace parameter identification. results show that characteristic a can reflect internal complex time series, series be quantified by extracted straightness differences diagrams three patterns. bubble most confused followed Mist flows'. Slug flows' regular. extraction recognition for gray fluctuation sequence gas-liquid two-phase...
In harsh environments, the corrosion damage of steel structures and equipment is a serious threat to operational safety service. this paper, Zn-Al diffusion layer was fabricated on 45 by Mechanical Energy Aided Diffusion Method (MEADM) at 450 °C. The microstructure composition, surface topography, electrochemical performance were analyzed before after corrosion. results show that are composed Al2O3 Γ1 phase (Fe11Zn40) δ1 (FeZn6.67, FeZn8.87, FeZn10.98) Zn-Fe alloy. There transition zone with...
In this paper, we propose a dual aggregation network to adaptively aggregate different information in infant brain MRI segmentation. More precisely, added two modules based on 3D-UNet better model at levels and locations. The dilated convolution pyramid downsampling module is mainly solve the problem of loss spatial process, it can effectively save details while reducing resolution. self-attention integrate remote dependence feature maps dimensions channel, improving representation ability...
Aimed at the problems of a high leakage rate, cutting injury and uneven root in existing combined garlic harvesting root-cutting technology, we researched key technologies used harvester for adaptive based on machine vision. Firstly, research was carried out conveyor alignment assembly to realize adjustment plant position bulb’s upper surface before roots were cut, establish parameter equations modify structure form system. Then, test using double-knife disk-type device examine ability...
This study was to explore the application value for central venous stenosis and occlusion in hemodialysis patients under CT angiography based on intelligent segmentation algorithm, so that can survive better. Spiral used examine upper limb swelling 62 uremic at a speed of 3.8 mL/s. Nonionic iodine contrast agent injected around contralateral limb. The total dosage 90-102 mL, it scanned by trigger technology. scanning threshold set. monitoring point located superior vena cava. with...
TiN films on 316L were deposited by Middle Frequency Unbalanced Magnetron Sputtering Plating (MF-UBMSP). The phase structure, roughness, thickness, surface morphology and colour of the assessed using X-Ray Diffraction (XRD), profilometer, Scanning Electron Microscope (SEM), spectrophotometer nanomechanics measuring instrument. characteristics compared with traditional Arc Ion (AIP). results show that can be steadily middle frequency unbalanced twin target magnetron sputtering under proper...
This paper carries out a questionnaire survey on 30 quality inspection institutions at the level of Ministry Agriculture, and based systematic analysis, analyzes causes difficulties in personal submission samples for from six aspects order to meet real needs agricultural product under new situation. In accordance with actual situation China's current regulatory system control system, this sets forth relevant recommendations correctly guide promote development system.
