Elasticity with arbitrarily shaped inhomogeneity

Casimir interaction of arbitrarily shaped conductors.

We review a systematic practical implementation of the multiple scattering formalism due to Balian and Duplantier (1977 Ann. Phys. 104 300, 1978 Ann. Phys. 112 165) for the calculation of the Casimir interaction between arbitrarily shaped smooth conductors. The leading two-point scattering term of the expansion has a simple compact form, amenable to exact or accurate numerical evaluation. It is...

Quasistatic relaxation of arbitrarily shaped sessile drops.

We study a spontaneous relaxation dynamics of arbitrarily shaped liquid drops on solid surfaces in the partial wetting regime. It is assumed that the energy dissipated near the contact line is much larger than that in the bulk of the fluid. We have shown rigorously in the case of quasi-static relaxation using the standard mechanical description of dissipative system dynamics that the introducti...

Digital Image Watermarking for Arbitrarily Shaped Objects

Many image watermarking schemes have been proposed in recent years, but they usually involve embedding a watermark to the entire image without considering only a particular object in the image, which the image owner may be interested in. This paper proposes a watermarking scheme that can embed a watermark to an arbitrarily shaped object in an image. Before embedding, the image owner specifies a...

Arbitrarily Shaped Virtual-object Video Compression

With the advancements in multimedia technologies, effective video compression has become more and more important. The size of the video files is always increasing with the increasing camera resolutions and because of never ending demand for better quality video signals. On the other hand, there is a limit to the available storage space and transmission bandwidth. Therefore, it is important to h...
