Abstract: Inputting data necessary for designing an IT system leads a throughput evaluation part to draft a system idea meeting a design standard value for throughput and leads a reliability evaluation part to draft the system idea meeting a design standard value for failure probability. A cost evaluation part evaluates a cost of the system idea, while a cost judgment part judges whether there exists a system idea whose cost evaluated by the cost evaluation part is within an allowable range or not. When the cost judgment part judges that there is no system idea, a reconfiguration part reconfigures the design standard value for throughput, the design standard value for failure probability, and the allowable range of cost in the input data part, and the reconfiguration part carries out calculations repeatedly until there can be drafted a system idea whose cost is within the allowable range.

Abstract: A system for correctly evaluating a price distribution and a risk distribution for a financial product or its derivatives introduces a probability density function generated with a Boltzmann model at a higher accuracy than the Gaussian distribution for a probability density. The system has an initial value setup unit and an evaluation condition setup unit. Initial values include at least one of price, price change rate, and the price change direction of a financial product. The evaluation conditions include at least time steps and the number of trials. The Boltzmann model analysis unit receives the initial values and the evaluation conditions, and repeats simulations of price fluctuation, based on the Boltzmann model using a Monte Carlo method. A velocity/direction distribution setup unit supplies the probability distributions of the price, price change rate, and the price change direction for the financial product to the Boltzmann model analysis unit.

Abstract: This disaster risk assessment system assesses a difference between a disaster-time direct loss amount in current equipment and disaster-time direct loss amount in equipment after taking measures and compares the difference with a disaster measures equipment cost for presenting decision making information on disaster measures. As assessment requirements, the system also takes a business value loss amount into consideration and presents an insurance premium that is required to cover an expected disaster-time loss amount by an insurance payment.

Abstract: The exhaust manifold gasket according to present invention consists of a pair of beaded plates provided with beads extending along the circumferences of exhaust holes therein, and a piled plate assembly inserted between these beaded plates. The piled plate assembly consists of a pair of flat plates, and a refractory sheet member disposed between these flat plates and containing a core plate therein. The refractory sheet member is formed out of a material having a high thermal resistance, excellent heat insulating characteristics and a high compression resiliency at a high temperature, such as a mica material. Accordingly, this exhaust manifold gasket has an improved compression resiliency at a high temperature and an improved sealability at a high temperature, and is capable of properly cutting off the transfer of heat.
