The late Archean (2.7 Ga) Schreiber-Hemlo and White River-Dayohessarah greenstone belts are characterized by tectonically juxtaposed volcanic and siliciclastic sedimentary rocks, which were collectively intruded by the syn- to post-kinematic, high-Al, high La/Ybn tonalite-trondhjemite-granodiorite (TTG) plutons. The volcanic rocks are composed of two distinct types of sequences: (1) komatiitic to...
A supervised learning algorithm for obtaining the template coefficients in completely stable Cellular Neural Networks (CNNs) is analysed in the paper. The considered algorithm resembles the well-known perceptron learning algorithm and hence called as Recurrent Perceptron Learning Algorithm (RPLA) when applied to a dynamical network. The RPLA learns pointwise defined algebraic mappings from initial-state...
The wave motion in a fluid-filled fracture embedded in an anisotropic medium is investigated using the technique of partial waves. A model is derived to calculate the complex dispersion relation of the Stoneley-wave mode in a fluid layer between two infinite transversely isotropic half-spaces. The effect of the anisotropic parameters on the Stoneley-wave in the fracture is investigated. The numerical...
