Higher-order effects of initial deformation on the vibrations of crystal plates
(Acoustical Society of America, 1977-02-01)
A system of plate equations for the thickness_shear and flexural vibrations superposed on large initial deflection due to bending is derived; in the stress–strain relations the terms associated with the fourth_order elastic ...
Concerning Transforms for Three-Valued Systems

Adiabatic Following in Two-Photon Transition
(American Physical Society, 1977-03-01)
The coherent interaction of two smoothly varying, near-resonant, two-photon pulses with a three-level system can be described by "two-photon damped Bloch equations" which are analogous to those for a one-photon transition ...
Structural Processing of Visual Information
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1977), CS77004-R
One lesson that has been learned from previous approaches to scene analysis is that local methods are insufficient for extracting reliable information about the contents of a scene. Two different procedures that have been ...
Divided Difference Methods for Galois Switching Functions
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1977), CS77005-R
An alternative is provided to a recently published method of Benjauthrit and Reed for calculating the coefficients of the polynomial expansion of a given function. The method herein is an adaptation to finite fields of ...
Prediction of the sound diffracted around barriers in large rooms using an extension of Maekawa's approach
(Acoustical Society of America, 1977)
A computer program has been developed for the prediction of sound pressure levels in large, irregular rooms utilizing a geometric acoustics approach. Experiments indicated that the program gave good predictive accuracy ...
A Markov Model of Cyclic Structured Programs
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1977), CS77002-R
The paper defines a class of flow graphs which possess neither absorbing nor transient states. It gives a necessary and sufficient condition that any transition matrix associated with such a program be primitive. With a ...
Third-order resonant wave interactions
(AIP Publishing, 1977)
An analysis is presented of third_order resonant interactions in capillary-gravity waves. When dissipation is accounted for, the theory predicts the amplitude of the third harmonic near the resonant frequency and at the ...
The Decomposition of Rademacher-Walsh Spectra
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1977), CS77007-R

Numerical-perturbation technique for the transverse vibrations of highly prestressed plates
(Acoustical Society of America, 1977-01-01)
Under the usual assumptions of small strains with moderately large rotations, the problem of the transverse vibrations of highly prestressed, nonuniform annular plates is reduced to the solution of the differential equation ...
