  • Publication number: 20040044613
    Abstract: For a comprehensive risk evaluation of the electricity price fluctuations, respective relationships between power supplies or power demands and electricity prices are derived from data of historical power supply or power demand and data of historical electricity price for respective power exchanges, respective probability distributions of electricity price fluctuations relating to uncertain fluctuations of the power supply or the power demand are computed by using the respective relationships in a given period for evaluation of a market risk, the market risk of electricity price is measured by using the respective probability distributions of electricity price fluctuations, a probability distribution for randomly fluctuating components is derived by Monte Carlo simulation, and a market risk to the electricity price fluctuations is evaluated.

  • Patent number: 5556640
    Abstract: There is provided a dry gel composition comprising 40% by weight or below of a medicine which can be orally administered, 3% by weight or above of a gelling agent and 5% by weight or below of a binder, which composition is capable of forming a gruel-like aqueous gel composition upon mixing with 2 to 15 parts weight of water per part by weight of the composition at a temperature of 40.degree. C. or below. The gelling agent usable herein is, for example, pregelatinized starch having a concentration of 50% by weight or above. The medicine which can be orally administered is, for example, cinnarizine. Upon mixing with a predetermined quantity of water, the dry gel composition forms a homogeneous aqueous gel composition having a viscosity of about 100 to 500 cp, which is preferably thixotropic. Even aged people having a weak swallowing function can easily swallow the aqueous gel composition, without causing improper sucking into their tracheas.
