In order to study the complex global dynamics of a series of blackouts in power transmission systems a dynamical model of such a system has been developed. This model includes a simple representation of the dynamical evolution by incorporating the growth of power demand, the engineering response to system failures, and the upgrade of generator capacity. Two types of blackouts have been identifi...

Lighting conditions of eight schoolrooms were investigated in order to obtain the appropriate lighting standards for schoolroom. The following results were obtained. 1) Lighting standards, which are applicable to schoolroom, were proposed by introducing a partial modification of Moon and Spencer's standards. 2) Generally, the values of delos, which is introduced by Moon and Spencer, were insuff...
