Abstract: A two-class classification/prediction model is generated in a simple operation by performing two-class classification with a classification rate substantially close to 100%. The two-class classification/prediction model is generated by a) obtaining a discriminant function for classifying a training sample set into two predetermined classes on the basis of an explanatory variable generated for each sample contained in the training sample set, b) calculating a discriminant score for each training sample by using the obtained discriminant function, c) determining, based on the calculated discriminant score, whether the training sample is correctly classified or not, d) determining a misclassified-sample region based on maximum and minimum discriminant scores taken from among misclassified samples in the training sample set, e) constructing a new training sample set by extracting the training samples contained in the misclassified-sample region, and f) repeating a) to e) for the new training sample set.

Abstract: A linker generates a simulator-use executable format program from a pre-conversion object program and a simulator-use object program. A simulator executes the simulator-use object program and acquires branch trace information. A binary program converting tool, based on the branch trace information and a branch penalty table, generates a post-conversion object program having a rewritten branching prediction bit of the pre-conversion object program. Another linker generates an actual-machine-use executable format program from the post-conversion object program and an actual-machine-use object program.
Abstract: A system and method to select a print area to be printed from a document, to search the selected print area for blank areas, and to print and/or store the selected print area, having a size of the searched blank areas turned into a predetermined size or other space marker. Thus, the number of printed pages is reduced by printing only parts of documents in which there exists data for printout. Similarly, readability is improved, and comparison of data with other documents is facilitated. Further, a user can easily select certain content titles in a document for printing and/or storage while skipping underlying data content, and so on, so as to increase the user's satisfaction with printout results.
Abstract: An IP address and a MAC address of each of communication devices connected to a plurality of communication ports provided in a switching hub device are associated in an ARP table. Also, priority information representing the communication priority of each communication device is received, and the received priority information is associated with the MAC address of the communication device. When no IP address of a transmission source included in a data packet received at each communication port exists in the ARP table, the IP address and the MAC address of the transmission source are added to the ARP table and priority information is attached to the ARP table.
Abstract: A mounting method for mounting an electronic component on a printed circuit board, the mounting method includes fixing a lower surface of a magnet panel to a magnetic body included in the electronic component by a magnetic force, seizing the electronic component by attracting a part of an upper surface of the magnet panel to an attaching unit, determining a position of the attracting unit to place the electronic component at a predetermined position with respect to the printed circuit board and releasing the attracting unit from the upper surface of the magnet panel.
Abstract: REDC (A*B) is calculated for the values A and B by using a Montgomery's algorithm REDC. The part related to the A*B is performed by the three-input two-output product-sum calculation circuit. One digit ai of the value A, one digit bj of the value B and a carry value c1 are input to the product-sum calculation circuit, and ai*bj+c1 is calculated thereat. The higher-order digit of the r-adic two-digit of the calculation result is used as the carry value c1, and the lower digit is used for a later calculation. Further, one digit ni of a modulo N for the REDC, a predetermined value m and a carry value c2 are input into the product-sum calculation circuit, and n*ni+c2 is calculated thereat. The higher-order digit is used as the carry value c2, and the lower digit is used for a later calculation.

Abstract: A method, medium, and system effectively compressing and/or restoring binary images. By compressing pixel values making up a 2×2 block in an input image, using representative values representing the pixel values and a pattern of the pixel values represented by the representative values, it is possible to effectively compress and/or restore binary images having little similarities between pixel values. In addition, by extracting compressed values and a pattern of pixel values making up a 2×2 block in an image, from compressed data of the 2×2 block, and restoring pixel values using the compressed values and the pattern, it is possible to effectively restore binary images.
Abstract: When a request is sent by a switching unit, relating to the use of at least one subset of a codec mode configuration for the establishment of a transcoder-free operation connection by a radio network controller, it is checked whether the at least one requested subset is supported by the radio network controller. If the at least one subset of at least one codec mode configuration is supported, a transcoder-free operation connection to the switching unit and to the communication terminal is established by the radio network controller. Furthermore, a message relating to the at least one subset of the codec mode configuration to be used is signalled from the radio network controller to the communication terminal for the transmission of data.

Abstract: An optical transmission system, where in an optical transmitter a detection bit having a specific pattern set according to the number of bits to be transmitted within one symbol time, is imparted with respect to a transmission signal in which transmission information has been encoded according to a preset format, and an optical signal generated by modulating light according to the transmission signal is transmitted to a transmission line. In an optical receiver, logic inversion or bit swap of received data is detected and compensated by using the detection bit included in the received signal, a decoding process of the compensated received signal is executed. As a result, when an optical signal capable of transmitting multi-bit information within one symbol time is transferred, it is possible to realize excellent transmission characteristics, by reliably compensating an error in received data caused by the modulation format or the multiplex system of the optical signal.
