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...
متن کاملSelf-Organization of Surface Transportation Networks
This research investigates the self-organization of surface transportation networks. Using a travel demand model coupled with revenue, cost, and investment models, experiments are run under a variety of parameters on a grid network. It is found that roads, contiguous sections of multiple links operating with similar characteristics, and hierarchies of roads emerge under a broad range of assumpt...
متن کاملSelf-Organization during Friction in Complex Surface Engineered Tribosystems
Self-organization during friction in complex surface engineered tribosystems is investigated. The probability of self-organization in these complex tribosystems is studied on the basis of the theoretical concepts of irreversible thermodynamics. It is shown that a higher number of interrelated processes within the system result in an increased probability of self-organization. The results of thi...
متن کاملTowards self-organization of decaying surface corrugations: A numerical study
We study numerically the interplay of surface topography and kinetics in the relaxation of crystal surface corrugations below roughening in two independent space dimensions. The kinetic processes are isotropic diffusion of adatoms across terraces and attachment-detachment of atoms at steps. We simulate the corresponding anisotropic partial differential equation for the surface height via the fi...
متن کاملSurface induced self-organization of comb-like macromolecules
We present a review of the theoretical and experimental evidence for the peculiar properties of comb copolymers, demonstrating the uniqueness of these materials among other polymer architectures. These special properties include an increase in stiffness upon increasing side-chain length, the spontaneous curvature of adsorbed combs, rod-globule transition, and specific intramolecular self-assemb...
