A Dual-Clock Stability Feature-Based Noise-Adaptive Clock Steering Approach for Single-Satellite Time Reference Generation [PDF]

Sensors
Clock steering, the core time-frequency technology for high-precision single-satellite time reference generation in global navigation satellite systems, can effectively combine the excellent short-term stability of Oven-Controlled Crystal Oscillators ...

Effects of the Wiener Process and Beta Derivative on the Exact Solutions of the Kadomtsev–Petviashvili Equation

Axioms, 2023
We take into account the (2 + 1)-dimensional stochastic Kadomtsev–Petviashvili equation with beta-derivative (SKPE-BD) in this paper. To develop new hyperbolic, trigonometric, elliptic, and rational solutions, the Riccati equation and Jacobi elliptic ...

The Influence of White Noise and the Beta Derivative on the Solutions of the BBM Equation

Axioms, 2023
In the current study, we investigate the stochastic Benjamin–Bona–Mahony equation with beta derivative (SBBME-BD). The considered stochastic term is the multiplicative noise in the Itô sense.

Solitary Wave Solutions for the Stochastic Fractional-Space KdV in the Sense of the M-Truncated Derivative

Mathematics, 2022
The stochastic fractional-space Korteweg–de Vries equation (SFSKdVE) in the sense of the M-truncated derivative is examined in this article. In the Itô sense, the SFSKdVE is forced by multiplicative white noise.

The Analytical Solutions of the Stochastic mKdV Equation via the Mapping Method

Mathematics, 2022
Here, we analyze the (2+1)-dimensional stochastic modified Kordeweg–de Vries (SmKdV) equation perturbed by multiplicative white noise in the Stratonovich sense.

A General Relative Radiometric Correction Method for Vignetting Noise Drift

Remote Sensing, 2023
Due to the limitation of the number of sensor pixels, optical splicing is commonly used to improve the imaging width of remote sensing satellites, and this optical stitching can cause vignetting in the image data of adjacent sensors. The weak energy, low

Asymptotic Properties of One Mathematical Model in Food Engineering under Stochastic Perturbations

Mathematics, 2021
For the example of one nonlinear mathematical model in food engineering with several equilibria and stochastic perturbations, a simple criterion for determining a stable or unstable equilibrium is reported. The obtained analytical results are illustrated

The stability analysis of stochastic opinion dynamics systems with multiplicative noise and time delays

IET Control Theory & Applications, 2021
This paper studies the stochastic stability of opinion formation systems under both non‐time delay and time delay. Individuals whose opinions are affected by multiplicative noise are considered.
