When the background noise is large or sound source far away from microphone array, localization accuracy of target sources will decrease dramatically. In order to solve this problem, a method multi-aperture acoustic array based on time difference arrival(TDOA) proposed. The constructed by two small sub arrays, which supposed surpass performance equivalent composed all microphones. positions in local coordinates are separately estimated arrays generalized trust-region sub-problem modified...
Abstract Surface damages on rail became severe with the increase in axle load and speed. Laser cladding was used to repair local surfaces ensure service performance prolong life of rails. In present study, five types materials (304, 314, 2Cr13, 316L, 434L) were clad at a small part (trapezoidal shape) disc simulate defected field. Vickers hardness tester, optical microscopy (OM), scanning electron (SEM), electron-dispersive X-ray spectroscopy (EDS) employed investigate properties repaired...
In this paper, Fe-based and Co-based alloy powders were chosen to perform laser cladding on wheel materials through conventional (CLC) ultra-high-speed (UHSLC) processes, respectively. The microstructures, element distribution, phase composition hardness of the coating layers using CLC UHSLC processes compared analysed. results show that coatings dense free defects such as pores cracks. Compared with coating, grain size was smaller, close powder design composition, distribution Cr within...
Smoothing of the graph convolution is not conducive to characterizing local differences point cloud. To solve this problem, we propose a Differential Graph Convolutional Network (Differ-GCN) for cloud analysis. First, new construction strategy that can make similar nodes in space belong same graph, which better represent commonality. After that, features are extracted by similarity matrix. Some smoothing information removed optimize over-smoothing and combined with difference points get...
