Simulation models for a variety of new water heater systems were developed and the models were integrated into a city-level residential energy end-use model for Osaka City. Using the model, the potential of energy conservation and CO2 emission-reduction by introducing new residential water...

A model is developed that simulates nationwide energy consumption of the residential sector by considering the diversity of household and building types. Since this model can simulate the energy consumption for each household and building category by dynamic energy use based on the schedule of...

This paper extends the Cass criterion for production efficiency to include uncertainty and uses it to show that a stock-market equilibrium in an overlapping-generations model with production uncertainty is efficient. It also develops a no-bubbles asset-pricing formula. Results are compared with...

In this paper we compare the regional network relationships of small and medium-sized enterprises (SMEs) in the mechanical engineering and related metal manufacturing industries in Japan and Germany. We show that the structure of network relationships is still largely determined by traditional...

We previously proposed the gas phase stoichiometric ratio (<em>SRgas</em>) as an index to evaluate NO<em>_x</em> concentration in fuel-rich flames. The<em> SRgas</em> index was defined as the amount of fuel required for stoichiometric combustion/amount of gasified fuel, where the amount of gasified fuel was the amount of...
