Profit-and-loss management information presentation method, profit-and-loss management information presentation device, and profit-and loss management information presentation process program

Even in the case of a material producing company that uses common main starting materials and has in-house organizations corresponding to manufacturing processes, appropriate profit-and-loss management by each commercial product type can be realized. A solving method includes: a profit-and-loss storing step of linking at least product type information and profit information to each other by each order of products with order record to be stored in an order record profit-and-loss database; an information search step of accepting specific information on the virtual inter-organ organization and search condition information at least including product type condition, and reading from the order record profit-and-loss database, at least product type information and profit information on an order matching the search condition information and on an order belonging to the virtual inter-organ organization matching the specific information on the virtual inter-organ organization; a profit information aggregating step of sorting the product type information by each product type of a product type classification scale indicated in the product type condition and aggregating profit information corresponding to respective product information sorted by each product type; and a profit-and-loss management information presentation step of presenting the aggregated profit information by each product type as the profit-and-loss management information.

High-speed signal search method device and recording medium for the same

The object of the present invention is to provide a high-speed signal search method, device, and a recording medium for the same that can obtain detection results equivalent to precisely moving a window over the entire region of the input signal even when there is not precise movement of a window over the entire signal.The present invention provides a first step that generates a feature quantity sequence for a pre-recorded reference signal; a second step that sets the input signal window for the input signal that has been input; a third step that generates a feature quantity sequence for the input signal of this input signal window; a fourth step that calculates the input signal similarity value showing the degree of similarity between the feature quantity sequence generated in the first step and the feature quantity sequence generated in the third step; a fifth step that calculates the skip width showing the amount that the input signal can be moved; and a sixth step that determines the position of the input signal window based on the skip width calculated in the fifth step, sets the input signal window to this position, and calculates the input signal similarity value for each position of the input signal window by repeating the third step to the sixth step; and further, determines whether or not the reference signal exists at the position that the input signal window presently shows in the input signal based on the result of comparing the input signal similarity value and the predetermined threshold value.

Echo signal processing equipment and method of Doppler speed measuring laser radar

The invention provides a Doppler velocity metering laser radar echoed signal processing unit and a method. The processing unit mainly comprises a signal storage module and a DSP module; wherein, the signal storage module is used for storing the echoed signals of a tested object; the echoed signals are digital signals which are converted by A / D; the DSP module is used for reading the echoed signals in the signal storage module and carrying out the FFT to obtain the power spectrum of the signals, and then the rough estimated frequency value is obtained according to the power spectrum; the power spectrum is carried out the inverse FFT and then the self correlation functions of the echoed signals are obtained, the correction frequency value is obtained according to the self correlation functions, the rough estimated frequency value and the correction frequency value are added to obtain the Doppler frequency of the echoed signals, and the movement velocity of the tested object is calculated according to the Doppler frequency. The device and the method combine the self correlation technology with the frequency deviation estimation improvement algorithm which is based on the frequency deviation correction, and the velocity of the test object can be effectively worked out.
