Yang–Baxter deformation as an $\boldsymbol {O(d,d)}$ transformation

An Adaptive All-odd Transformation Watermark Scheme

Combining discrete wavelet transform, human visual system, chaotic map and odd-even quantization, a novel watermarking scheme for 2D images is proposed in this paper. Encrypted watermarking and identity information are imperceptibly embedded in 2D images according to this scheme. For improving the accuracy of just noticeable distortion and enhance robustness of algorithm, the model adaptively a...

Pattern transformation triggered by deformation.

Periodic elastomeric cellular solids are subjected to uniaxial compression and novel transformations of the patterned structures are found upon reaching a critical value of applied load. The results of a numerical investigation reveal that the pattern switch is triggered by a reversible elastic instability. Excellent quantitative agreement between numerical and experimental results is found and...

Deformation-induced phase transformation in zinc sulphide

There are two crystalline modifications of zinc sulphide. The high-temperature hexagonal (e) phase and the low-temperature cubic (/~) phase exhibit a reconstructive transformation at a transition temperature of about 1020 ° C. The transformation of e phase back to ~ phase is a sluggish process compared to that of/3 to :~ [1], therefore once it is formed the a phase will remain as a metastable p...
