Accurate evaluation of a polynomial in Chebyshev form
Applied Mathematics and Computation, 2011 The authors propose a compensated Clenshaw algorithm to evaluate a polynomial in Chebyshev form, based on error-free transformations. Forward error bounds are established and numerical tests illustrate the efficiency of the new method for evaluating the polynomial in the neighborhood of a multiple root and near the ends of the standard interval.

Accurate closed-form solution of the SIR epidemic model
Physica D: Nonlinear Phenomena, 2020 An accurate closed-form solution is obtained to the SIR Epidemic Model through the use of Asymptotic Approximants (Barlow et. al, 2017, Q. Jl Mech. Appl. Math, 70 (1), 21-48). The solution is created by analytically continuing the divergent power series solution such that it matches the long-time asymptotic behavior of the epidemic model.

Accurate parallel form filter synthesis
Electronics Letters, 1996 Standard algorithms for synthesising parallel form digital filters are adequate for basic applications. However, recursive filters required in acoustics synthesis applications often have very high orders, and errors from filter synthesis can become intolerable. The authors describe a new method for synthesising parallel form recursive filters.

APL Materials, 2017 Herein, we elucidate how to accurately quantify glass-forming ability (GFA) by measuring effective volume relaxation of supercooled melt. We propose a new parameter, denoted as κ, for representing the relaxation, which is calculated by combining ...
