Abstract: Some embodiments process facial images to ensure the inmate present for release is the actual inmate to be released. One embodiment includes receiving a facial image and a data identifier of a person. This embodiment further includes processing the facial image of the person in view of facial image data of the person to determine whether the received facial image matches the retrieved facial image data. The facial image data may be retrieved based on the data identifier of the person, facial landmark data extracted from the facial image, or otherwise. When the received facial image and the retrieved facial image data of the person match, an indicator of a match and a successful release identity verification is output. When there is not a match, an indicator of a failed release identity verification is output.

Abstract: A computer-implemented system, method, and software are provided for solving linear systems of equations arising in reservoir simulation. A linear system of fluid flow equations, including a plurality of unknown variables, is provided that represents fluid flow properties in a geological formation of a subterranean reservoir. Block diagonal scaling is applied to the linear system of fluid flow equations. Threshold incomplete lower-upper approximate factorization is applied to obtain a preconditioning matrix, which can be used to iteratively solve unknown variables associated with the system of fluid flow equations. Preconditioning can be used directly as part of a preconditioned Krylov subspace method or alternatively as a 2nd stage preconditioner in a CPR algorithm.

Abstract: A method for conducting a stress calculation is disclosed adapted for modeling a set of stresses and displacements in a reservoir, the method comprising: (a) building a reservoir model over a region of interest by gridding the region of interest, the grid being comprised of one or more cells and having nodes, each cell having a cell center; (b) interpolating unknown rock displacements in the region of interest from cell centers to grid nodes; (c) integrating over each cell to form a discrete system of equations; and (d) using the discrete system of equations to model the stresses and displacements in the reservoir.

Abstract: A method for increasing oil recovery from an oil reservoir in which method surplus gas streams from a plant for synthesis of higher hydrocarbons from natural gas is injected into the reservoir, is described. The surplus streams from the plant is the tailgas from the synthesis and optionally nitrogen from an air separation unit which delivers oxygen or oxygen enriched air to the plant for synthesis of higher hydrocarbons.
