چکیده
The hydriding kinetics of hydrogen storage materials in the two-phase regions have been studied. It is believed that the hydriding process is best classified into three steps: dissolution of hydrogen into the alloy or its hydride; diffusion of hydrogen atoms through the alloy or its hydride phase; and nucleation and growth of B-hydride (hydride depositing from supersaturated a-solid solution). Kinetics equations have heen derived for the cases when one of the three steps is the rate-determining step.

Moving object recognition in eigenspace representation: gait analysis and lip reading
This paper describes a new method to calculate the spatio-temporal correlation efficiently in a parametric eigenspace representation for moving object recognition. A parametric eigenspace compactly represents the temporal change of an image sequence by a trajectory in the eigenspace. This representation reduces the computational cost of correlation-based comparison between image sequences. Expe...

We construct a simple model of an elastic material whose stiffness can be effectively controlled by an appropriately chosen set of microstructural parameters. The model is based on ideas of the scale-dependent continuum description and might play an important role in modelling of muscle tissues in biomechanics. © 2002 IMACS.

We introduce a method for characterizing the expressive power of concept expressions in firstorder description logics. The method is essentially model-theoretic in nature in that it gives preservation results uniquely identifying a wide range of description logics as fragments of first-order logic. The languages studied in the paper all belong to the well-known ,Y'/~and ,AZ~ hierarchies. © 1999...
متن کاملDynamics of a random neural network with synaptic depression
Abstract--We consider a randomly connected neural network with linear threshoM elements which update in discrete time steps. The two main features o f the network are: (1) equally distributed and purely excitatory connections and (2) synaptic depression after repetitive firing. We focus on the time evolution of the expected network activity. The four types of qualitative behavior are investigat...
متن کاملA multi-component nonlinear prediction system for the S&P 500 Index
The proposed stock market prediction system is comprised of two preprocessing components, two specialized neural networks, and a decision rule base. First, the preprocessing components determine the most relevant features for stock market prediction, remove the noise, and separate the remaining patterns into two disjoint sets. Next, the two neural networks predict the market’s rate of return, w...
