In this paper, development of the wind power generation data processing system with the aid of a micro computer is discussed. The system comprises two parts, i.e. a data measuring device and a data collecting/processing device. With the micro computer, control for data collection is maintanied...

The aim of this work is to investigate a method of measuring windmill torque loss coefficients of a windmill power system. We discussed the mathematical windmill model and defined the windmill torque loss coefficients. An estimating technique based on Kalman filtering was developed for decision...

In Japan, many local mixed enterprises owned and operated jointly by local governments and private sectors had been established from the late 1980's to the early 1990's in order to provide public services more efficiently. At present, in Japan, many local mixed enterprises are confronted with a...

The main purpose of this paper is to evaluate how the form and urban policies of ga compact city h affect its economic activities. In general, bigger cities have more advantages such as agglomeration economies, but too-big cities have the disadvantages of external diseconomies such as...

A rigid lattice gas model of solid-liquid, liquid-gas, and solid-gas transformations is proposed. The total free energy is separated into a lattice part and a vibrational correction part. It is reported that the vibrational part plays an important role in obtaining the gas, liquid and solid...

The two-dimensional thermal analysis code TAC-NC is modified from the analytical code TAC-2D in order to calculate temperature transients in the case of loss of forced cooling accidents of the HTTR (High Temperature engineering Test Reactor) such as a depressurization accident. The TAC-NC code...
