An Improved WENO-Z Scheme for Hyperbolic Conservation Laws with New Global Smoothness Indicator

open access: yesMathematics, 2023
The fifth-order WENO-Z scheme proposed by Borges et al., using a linear combination of low-order smoothness indicators, is designed to provide a low numerical dissipation to solve hyperbolic conservation laws, while the power q in the framework of WENO-Z

SAMS-Net: A Smoothness-Anchored Monotone Neural Differential Equation Network for Failure-Only-Supervised Structural Health Indicator Construction [PDF]

open access: yesSensors
Structural health monitoring (SHM) of fibre-reinforced composites requires a health indicator that is monotonically non-decreasing under the standard SHM assumption that no self-healing or maintenance-induced restoration event is active, derived from ...

Phase structure and machine learning identification in one dimensional systems with power law correlated disorder and long range hopping [PDF]

open access: yesScientific Reports
We investigate a one-dimensional tight-binding model in which onsite potentials $$\{\varepsilon _i\}$$ exhibit power-law spatial correlations (with exponent $$\alpha$$ ) and the hopping amplitudes decay as $$t_{ij}\sim |i-j|^{-\beta }$$ .

Hybrid Hermite TENO scheme with a simple smoothness indicator for compressible flow simulations

open access: yesResults in Applied Mathematics, 2022
The Hermite targeted essentially non-oscillatory (HTENO) scheme offers an excellent small-scale resolution and better shock-capturing capability in solving compressible flow problems.

The missing censoring indicator model and the smoothed bootstrap [PDF]

open access: yesComputational Statistics & Data Analysis, 2008
For right censored data with missing censoring indicators, sub-density function kernel estimators play a significant role for estimating a survival function. Data-driven bandwidths for computing these kernel estimators are proposed. The bandwidths are obtained as minimizers of certain estimates of the mean integrated squared error (MISE).
