Some new soliton solutions of a semi-discrete fractional complex coupled dispersionless system

Scientific Reports, 2023
In this paper, a semi-discrete fractional derivative complex coupled dispersionless system is proposed. The properties of M-fractional derivative are utilized to convert discrete M-fractional derivative system to a classical discrete differential system.

Binaural Acoustic Scene Classification Using Wavelet Scattering, Parallel Ensemble Classifiers and Nonlinear Fusion

Sensors, 2022
The analysis of ambient sounds can be very useful when developing sound base intelligent systems. Acoustic scene classification (ASC) is defined as identifying the area of a recorded sound or clip among some predefined scenes.

Adaptive interference suppression based on an invariant subspace of matrices matching for a horizontal array in underwater acoustics [PDF]

JASA Express Letters
Passive detection of target-of-interest (TOI) within strong interferences poses a challenge. This paper introduces an adaptive interference suppression based on an invariant subspace of matrix matching. Assume that the TOI-bearing intervals are known. We

Rayleigh-Ritz majorization error bounds with applications to FEM [PDF]

, 2009
The Rayleigh-Ritz (RR) method finds the stationary values, called Ritz values, of the Rayleigh quotient on a given trial subspace as approximations to eigenvalues of a Hermitian operator $A$.

Cross-View Feature Learning via Structures Unlocking Based on Robust Low-Rank Constraint

IEEE Access, 2020
The cross-view multimedia are widely existed and attract many attentions in recent years. Nevertheless, it is noted that the phenomenon, that data in different classes from same view are more similar than that in same class from different views, is ...
