Dynamical toy model of interacting agents robustly exhibiting Zipf's law
Tohru Tashiro, Megumi Koshiishi, Tetsuo Deguchi
We propose a dynamical toy model of agents which possess a quantity and have an interaction radius depending on the amount of the quantity. They exchange the quantity with agents e…
Dynamics to the universal structure of one-dimensional self-gravitating systems in the quasi-equilibrium state
Tohru Tashiro
We investigate the quasi-equilibrium state of one-dimensional self-gravitating systems. If the null virial condition is satisfied at initial time, it is found that the number densi…
Neo-logistic model for the growth of bacteria
Tohru Tashiro, Fujiko Yoshimura
We propose a neo-logistic model that can describe bacterial growth data precisely. This model is not derived by modifying the logistic model formally, but by incorporating the synt…
Universal structure of two and three dimensional self-gravitating systems in the quasi-equilibrium state
Tohru Tashiro
We study a universal structure of two and three dimensional self-gravitating systems in the quasi-equilibrium state. It is shown numerically that the two dimensional self-gravitati…
Hierarchical Bass model
Tohru Tashiro
We propose a new model about diffusion of a product which includes a memory of how many adopters or advertisements a non-adopter met, where (non-)adopters mean people (not) possess…
Hierarchical logistic equation to describe the dynamical behavior of penetration rates
Tohru Tashiro, Hiroe Minagawa, Michiko Chiba
We propose a hierarchical logistic equation as a model to describe the dynamical behavior of a penetration rate of a prevalent stuff. In this model, a memory, how many people who a…
