摘要： A method for hiding message information into media information in frequency space. The data hiding method has high resistance to removal or change of message information embedded into media information and effectively maintain hidden message information even when signal processing is performed by employing a frequency filter. More specifically, in order to hide message information (m) into media information (M), the frequency transform of the message information (m) and the media information (M) are performed, and frequency spectra f1 and f2 are obtained. Next, from the frequency spectrum f2 of the message information (m), a region containing feature frequency components representative of the features of the message information (m) in real space is extracted as the base region B. Then, n copies of the base region B are generated, and in frequency space, the n copies are dispersedly arranged.

摘要： There have been problems in the facility information management system arts because when a distance-based facility database is searched for the facility information by specifying the name and distance of a facility, the location and position of a specific facility must be found on a figure such as a map. Such a location is not easily pointed out especially when the facility is damaged. To overcome the above problems, the present invention relates the distance-based facility data with map data and allows a generation of graphical figure data to be overlaid on a map from the numerical data corresponding to the facility parameters stored in the distance-based facility data.

摘要： To allow automatic determination of the order of drilling in slot drilling.The positions of holes located along a line are described via a binary vector. The order of drilling is also described via a binary vector. The former binary vector is made to correspond to the latter binary vector through a conversion matrix, where every corresponding partial matrix is regular. The positions of the holes are determined from the drilling order, or the drilling order is determined from the positions of the holes by their correspondence.
