Electrical capacitance tomography (ECT) is used to image the permittivity distribution of an object by measuring the mutual electrical capacitance between sets of electrodes mounted on its periphery. Reconstruction of the cross-section images in ECT system from the capacitance measurements is a nonlinear and illposed inverse problem. However, there are many algorithms to solve the inverse probl...

Moisture distribution information is a critical element in drying processes. The of products by employing high-power microwave (MW) technology widely used the industry. Although microwaves allow volumetric and selective heating resulting significant reduction processing time energy consumption, there always risk non-uniform moisture final product. This paper investigates capability designed ele...

Electrical capacitance tomography (ECT) attempts to reconstruct the permittivity distribution of the cross-section of measurement objects from the capacitance measurement data, in which reconstruction algorithms play a crucial role in real applications. Based on the robust principal component analysis (RPCA) method, a dynamic reconstruction model that utilizes the multiple measurement vectors i...

Electrical capacitance tomography (ECT) is a non-invasive imaging technique that aims at visualization the permittivity distribution of dielectric materials based on the measured capacitances. In this paper, the 3D finite element models of a direct 3D ECT sensor with or without dielectric spheres inside the sensor are set up by using finite element modeling. The sensitivity analysis of the sens...

The gas-solid-liquid three-phase flow is a very complicated flow pattern in pipeline transportation. By using electrical capacitance tomography (ETC) it can acquire the permittivity distribution of the multi-phase. The sensitivity distribution in ETC may affect the analysis of the permittivity distribution of the multi-phase. However, very limited work has been done in this issue. In order to i...

In air/oil lubrication systems, the flow parameters, e.g., flow pattern, liquid film thickness, and air/oil flow rate, are of great importance to the transportation efficiency. In most cases, the on-going two-phase flow is annular flow with the oil moving along the tube wall and the air travelling at high speed in the center. This usually results in the formation of a thin oil film, the thickne...

Introduction: Intracerebral hemorrhage (ICH) is a devastating disease with high rates of mortality and disability. The survival rate postoperative outcome ICH can be greatly improved through prompt diagnosis treatment. CT MRI are now the gold standards for ICH, but they not practical use in pre-hospital emergencies or at bedside monitoring. Methods: Based on earlier research detection single pa...
