In this paper we study the stability of(p,Y)-operator frames.We firstly discuss the relations between p-Bessel sequences(or p-frames) and(p,Y)-operator Bessel s
The multi-fault phenomena are common in the turbo-rotor system of a liquid rocket engine. As it has many excellent qualities, the neural network might be used t
In this paper, the well-known Duf fing equation and the nonlinear equation describing vibration of the human eardrum are introduced from elastic nonlinear syste
This paper concerns an experimental vibration analysis on the crack that appeared early on an automobile gearbox. We conduct the testing vibration analysis and
We study biharmonic submanifolds in δ-pinched Riemannian manifolds,and obtain some sufficient conditions for biharmonic submanifolds to be minimal ones.
