Ultrasonic Newton's rings
Abstract
Interference fringes due to bondline thickness variation were observed in ultrasonic scans of the reflected echo amplitude from the bondline of adhesively joined aluminum skins. To demonstrate that fullfield interference patterns are observable in pointbypoint ultrasonic scans, an optical setup for Newton's rings was scanned ultrasonically in a water immersion tank. The ultrasonic scan showed distinct Newton's rings whose radii were in excellent agreement with the prediction.

Static and tracking state estimation in power system using newton's method
This paper describes the Newton method for state estimation in electric power systems using the weighted least square approach (WLS). The information matrix that approximates the Hessian matrix in the WLS estimator is updated using the BrownDennis technique such that the linear convergence of the WLS algorithm is improved to nearly second order convergence of the Newton method. This proposed method is particularly effective in state estimation of illconditioned power systems which encounter difficulties in converging to the solution. The additional computing time for implementing the new algorithm is quite small as the nonzero elements of the hessian matrix aremore » 
Relation between the solutions of Newton's and Heisenberg's equations of motion
For a class of problems it is shown that a solution to Newton's equation of motion may be interpreted as the generating function for the matrix elements of the coordinate operators in the Heisenberg representation. For three onedimensional problems, the harmonic oscillator, the particle in a box, and the x/sup 4/ anharmonic oscillator, solutions to the quantummechanical problem are given in terms of the classical solution. A brief examination is made of a twodimensional problem in which the angular momentum is conserved. 
Application of a primitive variable Newton's method for the calculation of an axisymmetric laminar diffusion flame
In this paper we present a primitive variable Newtonbased solution method with a blockline linear equation solver for the calculation of reacting flows. The present approach is compared with the stream functionvorticity Newton's method and the SIMPLER algorithm on the calculation of a system of fully elliptic equations governing an axisymmetric methaneair laminar diffusion flame. The chemical reaction is modeled by the flame sheet approximation. The numerical solution agrees well with experimental data in the major chemical species. The comparison of three sets of numerical results indicates that the stream functionvorticity solution using the approximate boundary conditions reported in themore »
