Noise Spectral of GML Noise and GSR Behaviors for FGLE with Random Mass and Random Frequency

open access: yesFractal and Fractional, 2023
Due to the interest of anomalous diffusion phenomena and their application, our work has widely studied a fractional-order generalized Langevin Equation (FGLE) with a generalized Mittag–Leffler (GML) noise.

Random Noise Suppression Method for Inertial Sensors Based on Complexing an AR Model and Adaptive SRUKF Kalman Filter under the PINS Alignment on a Stationary Platform

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. In the gyrocompassing mode, the initial heading angle of a platformless inertial navigation system (PINS) is determined based on the data obtained from accelerometers and gyroscopes that measure the projections of the gravitational ...

A Natural Images Pre-Trained Deep Learning Method for Seismic Random Noise Attenuation

open access: yesRemote Sensing, 2022
Seismic field data are usually contaminated by random or complex noise, which seriously affect the quality of seismic data contaminating seismic imaging and seismic interpretation. Improving the signal-to-noise ratio (SNR) of seismic data has always been

Equivalent qubit dynamics under classical and quantum noise

open access: yes, 2007
We study the dynamics of quantum systems under classical and quantum noise, focusing on decoherence in qubit systems. Classical noise is described by a random process leading to a stochastic temporal evolution of a closed quantum system, whereas quantum ...

Effects of the low frequencies of noise on On-Off intermittency [PDF]

open access: yes, 2006
A bifurcating system subject to multiplicative noise can exhibit on-off intermittency close to the instability threshold. For a canonical system, we discuss the dependence of this intermittency on the Power Spectrum Density (PSD) of the noise.

Shallow Profile Data Denoising Method Based on Improved Cycle-consistent Generative Adversarial Network

open access: yesCT Lilun yu yingyong yanjiu, 2023
This study applied the cycle-consistent generative adversarial network method to the denoising of shallow profile data to realize intelligent denoising. This could help resolve the problem of noise and low resolution of shallow profile data.

Transient behavior of a population dynamical model [PDF]

open access: yes, 2004
The transient behavior of an ecosystem with N random interacting species in the presence of a multiplicative noise is analyzed. The multiplicative noise mimics the interaction with the environment.

Transcranial random noise stimulation (tRNS): a wide range of frequencies is needed for increasing cortical excitability

open access: yesScientific Reports, 2019
Transcranial random noise stimulation (tRNS) is a recent neuromodulation protocol. The high-frequency band (hf-tRNS) has shown to be the most effective in enhancing neural excitability.
