In this paper we propose a semi-fragile watermarking scheme, which can be used for image authentication. Let the originalimage be performed by l-level discrete
This article is concerned with the extended homogeneous balance method for studying the abundant localized solution structure of the (2 + 1)-dimensional asymmet
For time-dependent inductive-capacitive coupled circuits, the quantum fluctuations in the component circuits and the coupling part are computed. Generation of s
Two-photon Jaynes-Cummimgs model is generalized to the case of Kerr medium in this paper. The field and atom are prepared initially in two-photon superposition
