Moment features have been applied in pattern recognition systems since the moment method was developed. In this paper, a set of moment features extracted from the newly developed Gegenbauer moment method for Chinese character recognition is proposed. Compared with the results based on other moment methods, the Gegenbauer moments can provide a modest improvement in terms of recognition for those...

Classical Coulomb systems at equilibrium, bounded by a plane dielectric wall, are studied. A general two-point charge correlation function is considered. Valid for any fixed position of one of the points, a new relation is found between the algebraic tail of the correlation function along the wall and the dipole moment of that function. The relation is tested first in the weak-coupling (Debye-H...

A Lagrangian numerical method based on impulse variables is analyzed. The relation between impulse vectors and vortex dipoles with a prescribed dipole moment is presented and used to adapt the high-accuracy cutoo functions of vortex methods for use in impulse-based methods. The long-time implementation of the impulse method is shown to contain a source of error whose growth in time renders impu...

AbsfraclThe influence of specifying a roll moment distribution to effect the handling dynamics of automobiles has long been appreciated by conventional automotive designers. With the advent of active suspension systems, it is now possible to actively vary the roll moment distribution via feedback control. Nonlinear vehicle dynamics are developed to describe the effect of roll moment distributio...

with respect to the new aspects of earthquake engineering in the area of performance besed design, accurate estimation of structural response becomes more important. this requires precise recognizing of relevant parameters in the behavior of structures and using proper methods for applying the effects of distribution of these parameters in the desired response. in this study the effect of distr...

This paper addresses digital techniques used to identify automatically those color photographs whose optical densities fall outside acceptable norms for a visual system. Targets are of two diierent kinds indicating the need for diierent recognition algorithms. First, the investigation focuses on color pictures showing high contrast in optical densities such as pictures taken with ash and pictur...

Neutron diffuse scattering and saturation magnetization experiments have been made on single crystals specimens of Fe3-,MnCSi with c = 0.164 and 0.284 at room temperature. Atomic clustering of Mn atoms on the B sublattice has been revealed. A model of magnetic moment distribution around Mn impurities has been developed and fitted to the experimental magnetic diffuse cross sections. RRsults obta...
