  • Computer-readable recording medium storing therein test data generating program, test data generating method, test data generating apparatus and information processing system
    Patent number: 9639454
    Abstract: A computer-readable recording medium storing therein a test data generating program to be executed by a computer, the program causing the computer to: generate, for each of a plurality of path conditions obtained by repeatedly performing symbolic execution, a simplified path condition by substituting a fixed value for a first symbolic variable included in the path condition; calculate, for each the simplified path condition, a value of the symbolic variable that satisfies the simplified path condition; generate test data including the values of the symbolic variable, the fixed values, and path conditions not subjected to simplification; and remove duplicative data from the test data that corresponds to a same path condition.
    Type: Grant

  • Sensor material, sensor and detection method for bio-substance
    Patent number: 6780647
    Abstract: Provided is a sensor material including at least a stimulus-responsive high polymer gel, a bio-substance-responsive material and a light modulation material. A sensor having at least the sensor material and an optical waveguide is also provided. Furthermore, provided are a detection method for a bio-substance using the sensor material in which a change in tone is detected on the basis of swelling or shrinking of the stimulus-responsive high polymer gel, and a detection method for transmitting light using a sensor material in which transmitting light is detected on the basis of swelling or shrinking of the stimulus-responsive high polymer gel.
