    Abstract: past positions of a plurality of composing elements indicated by various past arrangement examples are given to each potential function corresponding to one composing element, and parameter values of the potential functions corresponding to the composing elements are automatically set on condition that a past total potential energy obtained by solving the potential functions is minimized. Thereafter, the parameter values are given to the potential functions in which a position of any composing element is not determined, and particular positions of the composing elements are determined on condition that a total potential energy obtained by solving the potential functions is minimized. Because each potential function corresponding to one composing element has an attraction term indicating the attraction between the composing element and the other composing elements and an attraction-repulsion term indicating the setting of the composing element at a position spaced at moderate distances from the other composing elements, the particular positions of the composing elements are set in an optimum arrangement. Accordingly, the optimum arrangement of the composing elements can be automatically obtained without extracting any arrangement knowledge from a skilled person.

    Abstract: A vibration type measuring instrument measures at least one of a mass flow rate and a density of a fluid flowing through a straight measurement pipe by vibrating the measurement pipe, obtains a frequency ratio of a resonant frequency of a first vibration mode to a resonant frequency of a second vibration mode of the measurement pipe, and corrects a measured value of at least one of the mass flow rate and the density according to the frequency ratio. The instrument includes a first vibration detector for detecting at least one of a vibration generated in the measurement pipe depending on the mass flow rate and the resonant frequency of the first vibration mode of the measurement pipe; and a second vibration detector for detecting the resonant frequency of the second vibration mode of the measurement pipe. The second vibration detector is provided around an antinode of the second vibration mode of the measurement pipe to improve the detection sensitivity in the second vibration mode.
