A time-dependent, two-dimensional model of a semiconductor laser array is numerically studied by means of Θand Newton-Raphson methods. A parallel version of the BiCGSTAB algorithm for the solution of the linear equations resulting from the Newton-Raphson technique is presented. It is shown that the proposed method reduces by half the number of messages and, by means of communications overlappin...

A new registration algorithm based on Newton-Raphson iteration is proposed to align images with rigid body transformation. A set of transformation parameters consisting of translation in x and y and rotation angle around z is calculated by optimizing a specified similarity metric using the Newton-Raphson method. This algorithm has been tested by registering and correlating pairs of topography m...

A novel technique for identifying soil parameters on-line while traversing with a tracked vehicle on unknown terrain is presented. This technique, based on the Newton Raphson method is used to identify unknown soil parameters. Comparing with the Least Square method, it shows that the Newton Raphson method is better in terms of prediction accuracy, computational speed, and robustness to initial ...

This paper is about an intriguing property of the continuous Newton-Raphson method for the minimization of a continuous objective function f : if x is a point in the domain of attraction of a strict local minimizer x then the flux line of the Newton-Raphson flow that starts in x approaches x from a direction that depends only on the behavior of f in arbitrarily small neighborhoods around x and ...

In this paper the performance of unified power flow controller is investigated in controlling the flow of po wer over the transmission line. Voltage sources model is utilized to study the behaviour of the UPFC in regulating the active, reactive power and voltage profile. This model is incorporated in Newton Raphson algorithm for load flow studies. Simultaneous method is employed in which equati...

This paper deals with possible algorithms, which may ensure numerical stability of Newton-Raphson method in load flow analysis. Although the Newton-Raphson method is frequently used, it may have difficulties to obtain convergence. Oscillations, divergence or even convergence to unfeasible solutions may appear using traditional procedures. Therefore, various techniques (such as update truncation...
