Abstract: A system and method for enhanced aircraft-based targeting senses RF emissions or other signals associated with a target while navigating a trajectory through a GPS-challenged airspace. While the target is being observed, the aircraft targeting system tracks GPS-challenged state vectors (e.g., via an onboard inertial reference system) and pressure altitudes consistent with each observation. When the aircraft emerges from the GPS-challenged airspace, the targeting system determines multiple GPS-driven subsequent absolute positions of the aircraft. The targeting system determines a refined estimate of the target location via batch factor graph optimization of measurements taken while inside and outside of the GPS-challenged airspace.

Abstract: Exemplary methodology, procedure, system, method and computer-accessible medium can be provided for authenticating a non-digital medium of a physical object, by receiving at least one image of video of at least one marked or unmarked region, and comparing the first microscopic image or video of at least one marked or unmarked region with at least one second microscopic image or video relating to the non-digital medium to determine if a similarity between the first and second microscopic images or videos matches or exceeds a predetermined amount.

Abstract: Exemplary systems, methods and computer-accessible mediums can receive information comprising a first speckle pattern(s) associated with a portion(s) of the paper. The information can be generated by an optical arrangement, and the first speckle pattern(s) can be compared with a second speckle pattern(s) to determine if a similarity measure based on local or global descriptors is of equal to a predetermined amount or within a predetermined range.

Abstract: An apparatus for providing a high level mobile virtual machine may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the apparatus to perform at least maintaining a record, at a service platform, of service software versions employed at one or more virtual machines, providing a service software upgrade from the service platform to at least one of the one or more virtual machines, and tracking which of the one or more virtual machines employs the service software upgrade. A corresponding method and computer program product are also provided.

Abstract: A mechanism for managing data communications is provided. A circularly arranged set of buckets is disposed between input buffers and output buffers in a networked computer system. Connections among the system and clients are stored in the buckets. Each bucket in the set is successively examined, and each connection in the bucket is polled. During polling, the amount of information that has accumulated in a buffer associated with the connection since the last poll is determined. Based on the amount, a period value associated with the connection is adjusted. The connection is then stored in a different bucket that is generally identified by the sum of the current bucket number and the period value. Polling continues with the next connection and the next bucket. In this way, the elapsed time between successive polls of a connection automatically adjusts to the actual operating bandwidth or data communication speed of the connection.

Abstract: A multiple opening sleeve valve is provided with a gate movable to control flow or pressure without the need for axial movement of a component through a pressure-containing seal. A gate actuator can include a drive rod and nut coupled to a gate substantially internal to the valve housing without the need for grease or similar external lubrication. The valve can provide for relatively high in-line gate-moving force, a reduction in force or torque requirements for operation, increased ease of wear-part replacement and decreased overall valve length, compared to previous valve configurations of comparable size or capacity.
