Statistics with Pseudo Random Numbers

Computer Intensive Statistics

Shingo Shirahata(Professor), Wataru Sakamoto(Associate Professor), Kei Hirose(Assistant Professor),

  In order to analyze statistical data, computer is a must-have item. However, the classical procedures are developed without the presupposition of the existing computers. Classical theory and methods are developed under the assumption that the underlying distributions follow normal distribution...

A New Direction in Nano-Mechanics

-Resonance Measurement for Nanomaterias-

Professor Masahiko Hirao, Associate Professor Hirotsugu Ogi, Assistant Professor Nobutomo Nakamura

   We have succeeded in measuring resonance frequencies in nanomaterials, including ultrathin films and nanowires, where representative dimensions are in 10 nanometers. This method uses the pump-probe technique, where the pump light pulse causes vibrations in the nanomaterials, which are det...

Computational materials design for semiconductor spintronics

Design of ‘co-doping’ for (Ga, Mn)As as a Route to higher TC

Prof. Hiroshi Katayama-Yoshida, Guest Associate Prof. Kazunori Sato

  In the present semiconductor electronics, information processing is realized by controlling the electric current. In principle, we can achieve high-speed computation by downsizing the processors and shortening the travel distance of electrons. However, it is easily recognized that this directi...

Physicochemical Properties and Functions of Gas Hydrates

A Key Component for Solving Global Environmental and Energy Issues

Professor: Kazunari Ohgaki, Associate Professor: Hiroshi Sato, Assistant Professor: Takeshi Sugahara

 Gas hydrate (clathrate hydrate) is a solid crystal composed of the cage-structure of water molecules and the gas molecule (such as H2, CH4) inside the cage.  One of the significant advantages of gas hydrate is “gas hydrate can store a large amount of gas inside it”. From the point ...
