Accurate variational forms for multiskyrmion configurations

Nuclear Physics A, 1989
Abstract Simple variational forms are suggested for the fields of a single skyrmion on a hypersphere, S3(L), and of a face-centered cubic array of skyrmions in flat space, R3. The resulting energies are accurate at the level of 0.2%. These approximate field configurations provide a useful alternative to brute-force solutions of the corresponding ...

Accurate RRAM transient currents during forming

Proceedings of Technical Program - 2014 International Symposium on VLSI Technology, Systems and Application (VLSI-TSA), 2014
The magnitude of overshoot current during forming has been shown to be a serious issue. Recently we showed that the overshoot duration is equally important in impacting device performance. Shorter duration overshoot in the range of ns yields better performance, suggesting extremely short forming pulse to be desirable.

More Accurate Hilbert-Type Inequalities in a Difference Form

Results in Mathematics, 2018
In the present paper we establish several more accurate Hilbert-type inequalities in a difference form. Our main results rely on some recent improvements of the Young inequality. First, we give refinements and reverses of the H\"{; ; ; o}; ; ; lder inequality.

Accurate closed-form approximations to partition functions

The Journal of Chemical Physics, 1991
We develop a method for obtaining accurate closed-form approximations to partition functions for all values of the temperature. The method is based on an alternative application of the Euler–Maclaurin summation formula and is therefore restricted to those partition functions which can be treated by such an approach.

Accurate closed-form solutions for fin-lines

1983 Eighth International Conference on Infrared and Millimeter Waves, 1983
Accurate closed-form expressions are derived for the theoretical prediction of equivalent dielectric constant, cutoff wavelength, and characteristic impedance of unilateral, bilateral and insulated fin-lines. The expressions developed on a physical basis are accurate to within ±0.6% and valid over the range of structural parameters 0 ≤ b/a ≤ 1, 1/32 ...
