  • Method of determining level of effect of system entity on system performance, by use of active time of same entity
    Patent number: 6978222
    Abstract: A method of determining the level of the effect of each system entity on the overall system performance, wherein the status of each entity at each one of discrete points of time is determined as the corresponding one of an active and an inactive status; the length of the active period in which each entity is situated without interruption in the active status is determined as an active time; and, on the basis of the relationship in magnitude between the system entities with respect to the determined active time, the level at which each entity affects the performance of the system is determined.
    Type: Grant

  • Method, computer program, and storage medium for estimating randomness of function of representative value of random variable by the use of gradient of same function
    Patent number: 6675126
    Abstract: A method of estimating a measure of randomness of a function of at least one representative value of at least one random variable is constructed to have the steps of obtaining the at least one random variable; determining the at least one representative value of the obtained at least one random variable; determining a first statistic of the obtained at least one random variable; determining a gradient of the function with respect to the determined at least one representative value; and transforming the obtained first statistic into a second statistic of the function, using the determined gradient. The step of transforming may be adapted to transform the first statistic into the second statistic, such that the second statistic responds to the first statistic more sensitively in the case of the gradient being steep than in the case of the gradient being gentle.
