Determination of a suitable initial estimate for a root of an equation ƒ(x) = 0 by means of computing the roots of a sequence of related equations is described.

Introduction: In dynamic PET analysis, the time-activity curves (TACs) observed in each tissue exhibit delays that deviate from the expected arterial input. Particularly in the context of Total-body ...

Abstract: The classical Newton-Raphson method is generalized to solve nonsquare and nonlinear problems of size m/spl times/n with m/spl les/n. Using this generalized Newton-Raphson method as a core, a ...

Abstract: This paper proposes a general formulation for implementing the fixed-point method (FPM) and the Newton-Raphson method (NRM) in finite-element (FE) analysis of nonlinear magnetic problems. As ...

This paper presents a method to directly extract the Jacobian matrix of a power system’s power flow (PF) equations in polar coordinates (termed as DEJMP method). This method is designed to reduce the ...
