| Research Abstract |
In this research project, linear and nonlinear nonequilibrium phenomena are studied based on molecular motion. It was shown that local distribution function depends on direction of molecular motion, and that nonlinear nonequilibrium phenomena could be reproduced using millions of particles. Thermally activated breakdown of some material under subcritical stress was studied using phenomenological model elements, and power-law dependence of its life time on material size was shown. Studies on variety and diversity of ecosystem and econosystem discovered that they are characterized by a stretched exponential distribution with exponent1/2.
