Power-like Tail Observed in Weight Distributions of Schoolchildren
Hiroto Kuninaka
We investigated the statistical properties of the weight distributions of Japanese children who were born in 1996, from recent data. The weights of 16- and 17-year-old male childre…
Home-run probability as a function of the coefficient of restitution of baseballs
Hiroto Kuninaka, Ikuma Kosaka, Hiroshi Mizutani
In baseball games, the coefficient of restitution of baseballs strongly affects the flying distance of batted balls, which determines the home-run probability. In Japan, the range…
Multiplicative Modeling of Children's Growth and Its Statistical Properties
Hiroto Kuninaka, Mitsugu Matsushita
We develop a numerical growth model which can predict the statistical properties of the height distribution of Japanese children. Our previous studies have clarified that the heigh…
Origin of rebounds with a restitution coefficient larger than unity in nanocluster collisions
Hiroto Kuninaka, Hisao Hayakawa
We numerically investigate the mechanism of super rebounds for head-on collisions between nanoclusters in which the restitution coefficient is larger than unity. It is confirmed th…
Fractal Structure of Isothermal Lines and Loops on the Cosmic Microwave Background
Naoki Kobayashi, Yoshihiro Yamazaki, Hiroto Kuninaka +4
The statistics of isothermal lines and loops of the Cosmic Microwave Background (CMB) radiation on the sky map is studied and the fractal structure is confirmed in the radiation te…
Statistical Properties of Height of Japanese Schoolchildren
Hiroto Kuninaka, Yu Mitsuhashi, Mitsugu Matsushita
We study height distributions of Japanese schoolchildren based on the statictical data which are obtained from the school health survey by the ministry of education, culture, sport…
