Publikováno v: 第27回宇宙エネルギーシンポジウム平成19年度 = The Twenty-seventh Space Energy Symposium. :126-130

A simplified method to compute static temperature using Microsoft Excel is presented in this report. There are two ways for prediction of temperature. One is transient temperature analysis, and the other is steady state analysis. For the thermal desi

Publikováno v: 宇宙航空研究開発機構特別資料 = JAXA Special Publication: Proceedings of Lectures and Workshop International: Recent Advances in Multidisciplinary Technology and Modeling. :77-87

In a pilot/automation interface, it is said that pilots tend to get confused about the unforeseeable behavior of automated airplanes when responding to an abnormal situation; such confusions trigger disasters. For preventing interference between auto

Consistency between continuous and discrete models: Another modeling problem in numerical simulation procedure

Autor: Aiso, Hideaki

In the procedure of numerical simulation, which is widely used in science and engineering research and development activities, there are two stages of modeling. First we describe the phenomenon that we simulate by mathematical equations. It is called
