Instability and finite-amplitude self-organization of large-scale coastline shapes

Large Scale Self-organization

Living cells need to impose inner order, transport organelles from site to site inside the cell, withstand external pressures and propagate themselves to different locations. All of these mechanical needs are supplied by the cells cytoskeleton. One of the components of the cytoskeleton is filamentous actin (F-actin). The two ends of F-actin are distinctly different, making it a polar rod with a...

Self-organization of Surface Shapes

A problem in surface modeling and approximation is how to sample a surface into a set of signiicant points. It is desirable that the sampling is done in such a way that best preserves the original shape. A principle is that highly curved area should be sampled densely and vice versa. This paper presents a self-organization method for automated surface sampling in this principle. Given a scale s...

The Superharmonic Instability of Finite-amplitude Interfacial Waves

The linear stability of finite-amplitude interfacial waves in a two-layer fluid is investigated for superharmonic disturbances on the basis of the Euler set of equations. In the previous study (J. Fluid Mech. 2006, vol.547, p.175), the author proved analytically for surface waves that the superharmonic instability first occurs when the wave energy density becomes stationary as a function of wav...
