Abstract: A diagnosis image reading control apparatus includes: a display controller configured to perform control to display multiple images on a display; a detector configured to detect a line of sight of a user on the display; a region determination unit configured to determine where the line of sight of the user is positioned in multiple regions divided in each of the images; and a luminance adjustment unit configured to adjust luminance of the images, wherein the luminance adjustment unit is further configured to adjust to increase luminance of the region designated by the line of sight of the user in the images.

Abstract: A method of uniforming physical random numbers while concurrently maintaining a random number generating rate and ensuring security. The method sequentially inputs a plurality of physical random numbers to a shift register to hold them there, and shifts them every time a reference pulse signal rises. Physical random numbers held in the shift register are randomly selected and output by a selector based on part of them. Accordingly, physical random numbers input to the shift register are uniformed and then output even thought they have a deviation, thereby eliminating the chance of not outputting random numbers or letting others recognize the deviation of random numbers.

Abstract: In a power plant including a plurality of parallel-operated generating elements supplying electricity and steam, boilers and turbines are controlled in an optimum condition depending on the successive changes of the demand for steam and electricity by: estimating parameters of characteristics and state of the generating elements, which cannot be directly measured, among parameters of the generating elements needed for calculation of the optimum load distribution for each of the generating elements, based on a physical model of each of the generating elements and an input process state quantity; and controlling each of the generating elements by determining an optimum load distribution for the each of the generating elements while using the estimated parameters of the each of the generating elements, to minimize a total cost of the power plant depending on the successive changes of the demand for steam and electricity.
