Smoothing of chromatographic signals by their approximation in the basis of Chebyshev-Hermite functions

open access: yesВестник Самарского государственного технического университета. Серия: Технические науки, 2022
The paper deals with assessing the scope of the approximation algorithm for smoothing chromatographic signals. The algorithm is based on Chebyshev-Hermite functions.

Prestack seismic random noise attenuation using the wavelet-inspired invertible network with atrous convolutions spatial pyramid

open access: yesFrontiers in Earth Science, 2023
Convolutional Neural Network (CNN) is widely used in seismic data denoising due to its simplicity and effectiveness. However, traditional seismic denoising methods based on CNN ignore multi-scale features of seismic data in the wavelet domain.

Seismic Random Noise Attenuation Based on PCC Classification in Transform Domain

open access: yesIEEE Access, 2020
Random noise attenuation of seismic data is an essential step in the processing of seismic signals. However, as the exploration environment is becoming more and more complicated, the energy of valid signals is weaker and the signal to noise (SNR) is much

On the Interplay between Entropy and Robustness of Gene Regulatory Networks

open access: yesEntropy, 2010
The interplay between entropy and robustness of gene network is a core mechanism of systems biology. The entropy is a measure of randomness or disorder of a physical system due to random parameter fluctuation and environmental noises in gene regulatory ...

Diffusion in Phase Space as a Tool to Assess Variability of Vertical Centre-of-Mass Motion during Long-Range Walking

open access: yesPhysics, 2023
When a Hamiltonian system undergoes a stochastic, time-dependent anharmonic perturbation, the values of its adiabatic invariants as a function of time follow a distribution whose shape obeys a Fokker–Planck equation.

Decentralized trade, random utility and the evolution of social welfare [PDF]

open access: yes, 2004
We study decentralized trade processes in general exchange economies and house allocation problems with and without money. The processes are subject to persistent random shocks stemming from agents' maximization of random utility.

Random Noise Attenuation Based on Residual Convolutional Neural Network in Seismic Datasets

open access: yesIEEE Access, 2020
Seismic random noise attenuation is a key step in seismic data processing. The random seismic data recorded by the detector tends to have strong noise, and this noisy seismic ratio can be seen as a low signal-to-noise ratio (SNR).

White Noise Representation of Gaussian Random Fields [PDF]

open access: yes, 2012
We obtain a representation theorem for Banach space valued Gaussian random variables as integrals against a white noise. As a corollary we obtain necessary and sufficient conditions for the existence of a white noise representation for a Gaussian random ...

Anticipating Stochastic 2D Navier-Stokes Equations [PDF]

open access: yes, 2011
In this article, we consider the two-dimensional stochastic Navier-Stokes equation (SNSE) on a smooth bounded domain, driven by affine-linear multiplicative white noise and with random initial conditions and Dirichlet boundary conditions.

ECG Signal De-noising and Baseline Wander Correction Based on CEEMDAN and Wavelet Threshold

open access: yesSensors, 2017
A novel electrocardiogram (ECG) signal de-noising and baseline wander correction method based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and wavelet threshold is proposed.
