Uncertainty principles for coupled fractional Wigner–Ville distribution

open access: yesRoyal Society Open Science
The coupled fractional Wigner–Ville distribution is a more general version of the fractional Wigner–Ville distribution. Main properties including boundedness, Moyal’s formula and inversion formula are studied in detail for the transformation ...

Feature Extraction of Gear Fault Signal Based on Sobel Operator and WHT

open access: yesShock and Vibration, 2013
Taking Wigner-Ville distribution of gear fault signal as a picture, Sobel operator was applied for edge detection of picture and then Hough transform was used to extract signal feature.

Dynamical entropic measure of nonclassicality of phase-dependent family of Schrödinger cat states

open access: yesScientific Reports, 2023
The phase-space approach based on the Wigner distribution function is used to study the quantum dynamics of the three families of the Schrödinger cat states identified as the even, odd, and Yurke–Stoler states.

A microscopic ancient river channel identification method based on maximum entropy principle and Wigner-Ville Distribution and its application

open access: yesPetroleum Exploration and Development, 2021
In view of the problem of fine characterization of narrow and thin channels, the maximum entropy criterion is used to enhance the focusing characteristics of Wigner-Ville Distribution.

Quark Wigner distributions in a light-cone spectator model

open access: yes, 2015
We investigate the quark Wigner distributions in a light-cone spectator model. The Wigner distribution, as a quasi-distribution function, provides the most general one-parton information in a hadron. Combining the polarization configurations, unpolarized,

Decoherence in Nanostructures and Quantum Systems [PDF]

open access: yes, 2003
Decoherence phenomena are pervasive in the arena of nanostructures but perhaps even more so in the study of the fundamentals of quantum mechanics and quantum computation.

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

The Interference Term in the Wigner Distribution Function and the Aharonov-Bohm Effect

open access: yes, 2001
A phase space representation of the Aharonov-Bohm effect is presented. It shows that the shift of interference fringes is associated to the interference term of the Wigner distribution function of the total wavefunction, whereas the interference pattern ...
