Abstract: Various systems, methods, and programs embodied in computer-readable mediums are provided for fingerprint liveness detection. In one embodiment, a method for determining fingerprint liveness is provided that comprises receiving a fingerprint image; extracting a region of interest from the fingerprint image; generating a histogram of the region of interest; determining a statistical feature of the histogram; and determining liveness of the fingerprint image based upon the statistical feature.

Abstract: Various systems, methods, and programs embodied in computer-readable mediums are provided for fingerprint liveness detection. In one embodiment, a method for determining fingerprint liveness is provided that comprises receiving a plurality of image analysis data of a fingerprint image; condensing the plurality of image analysis data; and determining liveness of the fingerprint image based upon the condensed data.

Abstract: A process and system for recovering protein and lipid from food animal byproducts, and the products thereof, involves homogenizing animal byproducts with water to form a homogenate, solubilizing the homogenate by adjusting the pH of the homogenate to form a first pH adjusted composition, separating the first pH adjusted composition forming a light fraction containing lipids (oil), a medium fraction containing protein in solution, and a heavy fraction containing fat-free impurities, separation by first centrifugation, adjusting the pH of the medium fraction to about the isoelectric point of the proteins thereby precipitating the medium fraction forming a second pH adjusted composition, and separating the second pH adjusted composition forming a light fraction containing water and a heavy fraction containing precipitated proteins. The water may then be recycled and used in the homogenization of further byproducts.

Abstract: A modular fiber reinforced polymer (FRP) composite deck module having one or more hexagonal components and one or more double trapezoidal components. A hexagonal component is a hexagonal cell with all sides being of equal length and forming a hexagonal space. A double trapezoidal component has a top side, a bottom side, a first trapezoid having a first top and a first bottom, and a second trapezoid having a second top and a second bottom. The first and second trapezoidal components are of equal dimensions and configured such that the first trapezoid is inverted resulting in the first top of the first trapezoid is adjacent to the second top of the second trapezoid, thereby creating a center seam and an extensive bonding surface. The double trapezoidal and hexagonal components are made of multiple layers of multi-axial fiber reinforcement and a resin matrix, the layers being continuous throughout the entire shape of the components.
