    Abstract: An improved system and method for composite record keys ordered in a flat key space for a distributed database is provided. A data schema may be created that defines a composite record key for data records in a canonical form. Composite record keys may then be constructed in canonical form defined by the data schema for each data record in data tables of a distributed database. An ordered index of composite record keys may then be built by inserting the composite record keys in canonical form into the index in sorted order. The index of composite record keys ordered in a flat key space for a distributed database may then be used for efficiently comparing or sorting distributed data records in the distributed database. The composite record keys ordered in a flat key space may be compared or sorted without referencing the data schema of the composite record keys.

    Abstract: The invention relates to a roll bending device for the control of profile and flatness in the rolling of metal plates or strips. In particular the invention relates to the well known principle of roll bending by using hydraulic cylinders to modify the load distribution between rolls of a rolling mill stand and a rolled stock e.g. a metal plate or a strip in order to control the profile and flatness of the metal plate or strip. A special design to allow safe roll bending even at large roll gauges is presented. The new design allows safe operation even at large roll gauges and high side loads.

    Abstract: A method of selective dithering for enhancing the printability of an image, including receiving input pixels of an original input image and identifying the pixel classification of the input pixels, where the pixel classification characterizes each of the plurality of pixels based, at least in part, on their respective gray values. Thereafter, a dither input is added to at least some of the input pixels to generate a filtered and dithered image, where the strength of the dither input applied to generate the filtered and dithered image is based on the pixel classification. Full dither may be applied for smooth pixels, and little or no dither may be applied for edge pixels.

    Abstract: A system can include a system processor that is programmed or adapted to classify pixels in a document image, and in some instances, to enhance the document image based upon such classification. Image data including pixels is received. For each pixel in some subset of the image data, a feature vector is generated. Each pixel in the subset is classified as text or image based upon its associated feature vector. The classifications can be outputted for storage and/or further processing. Further processing can include pixel level enhancement processing. Such enhancement processing can include application of a sharpening filter to pixels classified as text and of a smoothing filter to pixels classified as image. In some instances, background suppression can be performed upon a subset of the image data prior to classification.
