A chaos-based software watermarking framework against several limitations of the existing watermark algorithms is proposed in this paper, in which the anti-reverse engineering technique and chaotic system are combined with the idea of Easter Egg software watermarking.

Attenuation characteristics analysis of viscoelastic wave in anisotropic medium;

Theory of Objective Motions of Wave Source and Receiver in Medium Body

The Influences of the Shock Thickness and Alfven Waves on the Particle Acceleration by the Diffusive Shocks

The paper discussed the working principle of atmospheric wave creator,the waves creted by the machine which was made on the basis of the principle were measured and compared to the theoretical data.

Representations between the planar, spherical, and cylindrical waves are descripted, and the explicit equations and example are also presented.

Since wavelet coefficient is related to reservoir well, high resolution small-scale signal after wavelet decomposition is reflection of fluid property in rocks for carbonate reservoir with little facies change.

In this paper, a discrete multi-generated wavelet systems ｛t_l,j~1/2Ψ_l(t_lj·-k b_l)1≤l≤r,j,k∈Z｝ is studied.

The author gives the wavelet characterizations of the new Hardy space L￣2H_R￣1(R￣+_2×R￣+_2) and its dual space CMO_2 (R×R) on the product domain in I.
