A physical model for acoustic signatures
(A I P Publishing, 1980-01)
A physical model is presented to explain the interference phenomenon that gives rise to the material‐dependent signature obtained from an acoustic reflection microscope. An approximate formula is derived for the peak ...
Sorption/desorption of Cs on clay and soil fractions from various regions of Turkey
The sorption desorption behaviour of Cs ion in the concentration region of 10−8 to 10−4 meqml−1 have been studied using clay and soil fractions from various regions of Turkey. The sorption curves for all the material studied ...
Tip induced localized states in scanning tunneling microscopy
(Institute of Physics Publishing Ltd., 1988)
We have investigated the Scanning Tunneling Microscopy (STM) of graphite with varying tip-to-surface distance. Using an LCAO type approach we showed that at small separations states are localized between the tip and the ...
Reflection coefficient null of acoustic waves at a liquid–anisotropic‐solid interface
(Acoustical Society of America, 1989-01)
he reflection coefficient of acoustic waves incident on a liquid–solid interface from the liquid side is numerically calculated for a general anisotropic solid oriented in any arbitrary direction. The reflection coefficient ...
Improvement of anisotropy sensitivity in the scanning acoustic microscope
Thr response of the conventional scanning acoustic microscope (SAM) to anisotropic materials is theoretically investigated. For this purpose, the reflection coefficient of plane acoustic naves incident on a liquid-solid ...
Manoeuvring-target tracking with the Viterbi algorithm in the presence of interference
The Viterbi algorithm is used to track a target in the presence of random interference, such as jamming. A nonlinear target motion and an observation which is modelled in a spherical coordinate system are considered. ...
Residues of singular holomorphic foliations

Iterative algorithms for solution of large sparse systems of linear equations on hypercubes
Finite-element discretization produces linear equations in the form Ax=b, where A is large, sparse, and banded with proper ordering of the variables x. The solution of such equations on distributed-memory message-passing ...
Finite state machines in state estimation for dynamic systems with an Nth order memory and nonlinear interference
The Viterbi decoding algorithm is used ,for the state estimation of’ dynamic systems having Nth order memory and nonlinear interference. The state model is a nonlinear ,function of the disturbance noise and discrete ...
A sequential dual simplex algorithm for the linear assignment problem
We present a sequential dual-simplex algorithm for the linear problem which has the same complexity as the algorithms of Balinski [3,4] and Goldfarb : O(n2) pivots, O(n2 log n + nm) time. Our algorithm works with the ...
