Noise Reduction in a Reputation Index [PDF]

open access: yesInternational Journal of Financial Studies, 2018
Assuming that a time series incorporates “signal” and “noise” components, we propose a method to estimate the extent of the “noise” component by considering the smoothing properties of the state-space of the time series. A mild degree of smoothing in the

Torsional vibration analysis of shaft with multi inertias

open access: yesScientific Reports, 2022
An analytical method is proposed to investigate the torsional vibration of the uniform circular shaft with multiple concentrated inertias. The governing equation is established based on the Hamiltonian principle and verified by the dynamical method.
