Abstract: According to various embodiments, the present teachings include inventory control policies that are defined in terms of functions of aggregate cost rates, involving thresholds ? and an order-up-to point S. An embodiment of the present teachings includes a method. The method includes tracking an inventory position of each of the plurality of items by a logistics network and determining an item cost rate for each of the plurality of items based on the tracked inventory position. The method also includes determining an aggregate cost rate for the plurality of items based on the determined item cost rates, comparing the aggregate cost rate with a cost rate threshold ?, and ordering the plurality of items to an order-up-to point S if the compared aggregate cost rate is greater than or equal to the cost rate threshold ?.
Abstract: A system, method, and apparatus for mark recognition in an image of an original document are provided. The method/system takes as input an image of an original document in which at least one designated field is provided for accepting a mark applied by a user (which may or may not have been marked). A region of interest (RoI) is extracted from the image, roughly corresponding to the designated field. A center of gravity (CoG) of the RoI is determined, based on a distribution of black pixels in the RoI. Thereafter, for one or more iterations, the RoI is partitioned into sub-RoIs, based on the determined CoG, where at a subsequent iteration, sub-RoIs generated at the prior iteration serve as the RoI partitioned. Data is extracted from the RoI and sub-RoIs at one or more of the iterations, which allows a representation of the entire RoI to be generated which is useful in classifying the designated field, e.g., as positive (marked) or negative (not marked).

Abstract: Systems and methods of lenticular printing are disclosed. The systems and methods include an imaging device to process a lenticular image from two or more original images interlaced together. A printer of the imaging device prints the lenticular image on a substrate. A UV-cured gel deposition system of the imaging device is configured to deposit a UV-cured gel on the printed lenticular image to serve as a lenticular lens. The printing of the lenticular image and the depositing of the lenticular lens occurs concurrently to reduce the amount of manufacturing required to produce the lenticular device.
Abstract: Disclosed are overcoat layers comprising an acrylic resin crosslinked with a glycoluril resin. The overcoat layers are useful in bias charge rollers because they reduce streaking and increase service lifetime.

Abstract: A computer implemented system and method for processing text are disclosed. Partially processed text, in which named entities have been extracted by a standard named entity system, is processed to identify attributive relations between a named entity or proper noun and a corresponding attribute. A concept for the attribute is identified and, in the case of a named entity, compared with the named entity's context, enabling a confirmation or conflict between the two to be determined. In the case of a proper name, the attribute's context can be associated with the proper name, allowing the proper name to be recognized as a new named entity.
Abstract: A data processing apparatus includes first and second unsupervised learning process units and a supervised learning process unit. The first unsupervised learning process unit classifies data of a first data group according to unsupervised learning, to perform dimension reduction for the first data group and to obtain first classified data. The second unsupervised learning process unit classifies data of a second data group according to the unsupervised learning, to perform dimension reduction for the second data group and to obtain a second classified data group. The supervised learning process unit performs supervised learning using, as a teacher, the first classified data group obtained by the first unsupervised learning process unit and the second classified data group obtained by the second unsupervised learning process unit to determine a mapping relation between the first classified data group and the second classified data group.
Abstract: A method of performing non-linear transformation of a digital image for contrast modification. The original video input is compared to a linear transformation with gain and offset; and, the differential of the change in gain or slope and the input image ? is multiplied by a factor m obtained from a look-up table and the product of m and ? added to the original input to obtain the output video.
Abstract: An image processing apparatus for converting a multiple gradation image into a binary or multivalue image by use of an area gradation method according to a screen cell is provided. The apparatus includes a receiving unit that receives an input pixel value of each pixel of the multiple gradation image and position information on the screen cell, an output unit that has a lookup table storing an output pixel value corresponding to the input pixel value in such a manner that an image is formed in which the output pixel value is increased or decreased with an increase in the input pixel value, and a screen line number is kept at a prescribed level with the increase in the input pixel value but a dot position is different, and that outputs the output pixel value at a pixel position on the screen cell corresponding to the position information by referring to the lookup table, according to the input pixel value and the position information received by the receiving unit.
Abstract: A machine, such as a phase change or solid ink printing apparatus, has at least one multiple supply unit in the form of an ink stick disposed therein. The ink stick has an electronically-readable memory device associated therewith, and the memory device has stored therein electronic data related to the ink stick and readable by the machine. The memory device may be attached to the ink stick and removed before the ink stick is used for printing in the machine. In another aspect, the memory device is attached to a container for the ink stick. The container may be a cartridge for use in the machine, or a container for packaging the ink stick. The machine may include a coupler configured to read electronic data from the memory device while the memory device is positioned external to the printing apparatus, thus allowing the machine to verify the suitability of the ink stick before it is installed in the machine.

Abstract: An image forming apparatus includes a receiving unit, an image forming unit, a determining unit, an analyzing unit and a control unit. The receiving unit receives image data. The image forming unit performs a predetermined image forming process based on the image data received by the receiving unit. The determining unit determines as to whether or not the image data contains a barcode pattern. When the determining unit determines that the image data contains the barcode pattern, the analyzing unit analyzes as to whether a drawing direction of the barcode pattern is a vertical direction or a horizontal direction. The control unit that controls, based on an analyzing result of the analyzing unit, the predetermined image forming process being performed for the barcode pattern by the image forming unit.
Abstract: There is provided a system for a print production facility, with print job processing departments, in which a wait time interval is determined for each recorded instance in which an output, from a set of multiple outputs, is delivered from a first one of the print job processing departments to a second one of the print job processing departments. A statistical metric value, representative of a wait time interval for the set of multiple outputs, is computed, and a workflow relationship between the print job processing departments may be altered when a total number of recorded instances and/or the statistical metric value exceed given references.
