The void distribution of specimens of Ottawa sand was quantified via Magnetic Resonance Imaging (MRI) technique. Two specimen reconstitution techniques, wet-tamping and air-pluviation, were used to generate the specimens. The specimen was prepared in a non-metallic triaxial cell. After fully saturated, the specimen with the cell was put inside a MRI device. Data was acquired at initial state and different stages of the conventional drained triaxial compression test. The acquired MRI data gives a direct measurement of the fluid phase in the voids, thus providing a complete picture...

This book not only provides a comprehensive introduction to neural-based PCA methods in control science, but also presents many novel PCA algorithms and their extensions and generalizations, e.g., dual purpose, coupled PCA, GED, neural based SVD algorithms, etc. It also discusses in detail various analysis methods for the convergence, stabilizing, self-stabilizing property of algorithms, and introduces the deterministic discrete-time systems method to analyze the convergence of PCA/MCA algorithms. Readers should be familiar with numerical analysis and the fundamentals of statistics, such as...
