Method for analyzing exponential decays [PDF]

open access: yesComputers & Chemistry, 1987
Abstract The non-linear least-squares routine KPS1 is presented for the analysis of data from counting experiments which follow single exponential decays. It gives appropriate weighting to individual points, is compact (52 statements) and converges more rapidly than the widely used CURFIT program of Bevington.

Self-restricting Noise and Exponential Relative Entropy Decay Under Unital Quantum Markov Semigroups [PDF]

open access: yesQuantum
States of open quantum systems often decay continuously under environmental interactions. Quantum Markov semigroups model such processes in dissipative environments.

Bearing Fault Diagnosis Based on Natural Adaptive Moment Estimation Algorithm and Improved Octave Convolution

open access: yesIEEE Access, 2020
Fault diagnosis of rolling bearing has been the focus of research. Bearing signals are often accompanied by similar information, resulting in redundancy between data.

Energy Decay Estimates of a Timoshenko System with Two Nonlinear Variable Exponent Damping Terms

open access: yesMathematics, 2023
This paper is concerned with the asymptotic behavior of the solution of a Timoshenko system with two nonlinear variable exponent damping terms. We prove that the system is stable under some specific conditions on the variable exponent and the equal wave ...

The practical electromagnetic effect in surface-enhanced Raman scattering observed by the lithographically fabricated gold nanosquare dimers

open access: yesAIP Advances, 2020
We experimentally investigated the practical electromagnetic effects in surface-enhanced Raman scattering (SERS), using the precisely fabricated array of gold nanosquare dimers. The array of gold nanosquare dimers was fabricated by electron-beam exposure

Exponential Decay for Nonlinear von Kármán Equations with Memory

open access: yesAbstract and Applied Analysis, 2013
We consider the nonlinear von Kármán equations with memory term. We show the exponential decay result of solutions. Our result is established without imposing the usual relation between g and its derivative.

Exponential decay of expansive constants [PDF]

open access: yesScience China Mathematics, 2013
A map $f$ on a compact metric space is expansive if and only if $f^n$ is expansive. We study the exponential rate of decay of the expansive constant of $f^n$. A major result is that this rate times box dimension bounds topological entropy.

Concentration dependence of the fluorescence decay profile in transition metal doped chalcogenide glass

open access: yes, 2007
In this paper we present the fluorescence decay profiles of vanadium and titanium doped gallium lanthanum sulphide (GLS) glass at various doping concentrations between 0.01 and 1% (molar).
