Cellulose crystallinity can be described according to the crystal size and the crystallinity index (CI). In this research, using Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) methods, we studied the crystallinity of three

We describe a deep convolutional neural network (CNN) approach for nonlinear electromagnetic (EM) inverse scattering problems. We evaluate the performance of the proposed CNN as a function of the number of layers using different metrics such as struc

Process tomography is a well established imaging modality to monitor a variety of flow processes in industrial applications. Traditionally, this has been done through imaging of a cross section of the domain. In recent years, much interest has been d
