Power system frequency estimation utilizing the Newton-Raphson method
, 1994 The paper describes a new algorithm for measuring frequency at a power system bus. The algorithm is based on the Newton-Raphson iterative method using the digitized voltage samples at a relay location.

A second order convergent trial method for a free boundary problem in three dimensions [PDF]
, 2015 The present article is concerned with the solution of a generalized Bernoulli free boundary problem in three spatial dimensions. We parametrize the free boundary under consideration over the sphere and apply a trial method which updates the free boundary

Dual Quantum Dot Molecular FRET Probes for Picomolar DNA Hexaplexing
Small Methods, EarlyView.Multiplexed quantification of six different DNA targets from a single 200 µL sample at picomolar concentrations was accomplished by spectrotemporal detection of time‐resolved FRET from a single Tb‐complex donor to two quantum dot acceptors using one‐color excitation and two‐color detection.

steel research international, EarlyView.An accurate moving boundary model for volume diffusion containing boundary conditions from trans‐interface diffusion (TID) simulates the austenite growth during cooling. TID of Cr, Mo, N and Ni enhance growth kinetics. Without TID, compositions of the interface region change, decreasing the driving force for growth and finally causing numerical ...

Method for determining relaxation factor for modified Newton-Raphson method
, 1992 In order to reduce the CPU time for the modified Newton-Raphson method which introduces a relaxation factor, the effect of the relaxation factor on the residual of the Galerkin method is examined in detail.

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections
Structural Concrete, EarlyView.Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...
