Three Dimensional Image Reconstruction Based on KSVD for Electrical Capacitance Tomography
Published 2020-08-01“…ECT (Electrical Capacitance Tomography)is one of the effective methods to measure the parameters of twophase flow The threedimensional image reconstruction of capacitance tomography is a sensor system based on multilayer electrode structure A new redundant sensitivity matrix is established to map the relationship between the dielectric constant distribution and the sensor reading by measuring the capacitance values between the same layer and the heterogeneous plate As a highly nonlinear simple linearization problem, there are mismatches in the position and size of the object being imaged To overcome these problems, and the greedy sparsity method is used to reconstruct the 3d image The redundant sensitivity matrix is constructed by using ksvd dictionary learning method and nonlinear simulation The typical structure of the object under test can be better captured by training the real data of the redundant sensitivity matrix The proposed method can also improve the image quality of the reconstruction by comparing the simulation experiments…”

SOURCES OF QUATERNARY POTASSIC VOLCANIC ROCKS FROM WUDALIANCHI, CHINA: CONTROL BY TRANSTENSION AT THE LITHOSPHERE–ASTHENOSPHERE BOUNDARY LAYER
Published 2016-12-01“…One scenario assumes ascending sub-lithospheric melts that mark the permeable lithosphere in a transtension area without melting of the lithospheric material; products of volcanic eruptions in such a zone show only the sub-lithospheric mantle material; components of magmatic liquids do not reveal any connection to the lithospheric structure. Another scenario yields a direct control of melting in lithospheric sources in an evolving transtensional structure. …”
