A Remark on Newton's Resistance Formula

ZAMM, 1999
Summary: We consider Newton's model for the resistance of a body in a rarefied gas. A derivation from first principles is given and it is proved that for incompressible fluids the resistance is also given by the Newton functional in leading order.

A Note on a Formula of Newton and an Extension Thereto.

Journal of the Staple Inn Actuarial Society, 1946
Letf(x), f″(x), f″(x)denoteafunction ofx, its first and second derivatives respectively. Iff(x), f″(x)are one-valued, finite and continuous, and f″(x) exists in the neighbourhood of the valueaofx, thenwhere o <θ< I. Suppose the valueais an approximation to a root of the equationf(x)= o, the true value of which isa + h.Equation (I ...

A New Variational Result for Quasi-Newton Formulae

SIAM Journal on Optimization, 1991
Summary: The recent measure function of \textit{R. H. Byrd} and \textit{J. Nocedal} [SIAM J. Numer. Anal. 26, 727-739 (1989)] is considered and simple proofs of some of its properties are given. It is then shown that the BFGS and DFP formulae satisfy a least change property with respect to this new measure.

A new class of quasi-Newton updating formulas

Optimization Methods and Software, 2008
In this paper, we propose a derivative-free quasi-Newton condition, which results in a new class of quasi-Newton updating formulas for unconstrained optimization. Each updating formula in this class is a rank-two updating formula and preserves the positive definiteness of the second derivative matrix of the quadratic model.

Parametric timing estimation with Newton–Gregory formulae

Concurrency and Computation: Practice and Experience, 2006
AbstractThis paper presents a novel method for parametric worst‐case execution time (WCET) estimation of loops. The method determines a parametric bound on the iteration space size of loops with both affine and non‐affine loop bounds in an efficient manner using a formulation based on Newton–Gregory interpolating polynomials.
