A virus detection system (VDS) (400) operates under the control of P-code to detect the presence of a virus in a file (100) having multiple entry points. P-code is an intermediate instruction format that uses primitives to perform certain functions related to the file (100). The VDS (400) executes the P-code, which provides Turing-equivalent capability to the VDS. The VDS (400) has a P-code data file (410) for holding the P-code, a virus definition file (VDF) (412) for holding signatures of known viruses, and an engine (414) for controlling the VDS. The engine (414) contains a P-code interpreter (418) for interpreting the P-code, a scanning module (424) for scanning regions of the file (100) for the virus signatures in the VDF (412), and an emulating module (426) for emulating entry points of the file. When executed, the P-code examines the file (100), posts (514) regions that may be infected by a virus for scanning, and posts (518) entry points that may be infected by a virus for emulating. The P-code can also detect (520) certain viruses algorithmically. Then, the posted regions and entry points of the file (100) are scanned (526) and emulated (534) to determine if the file is infected with a virus. This technique allows the VDS (400) to perform sophisticated analysis of files having multiple entry points in a relatively brief amount of time. In addition, the functionality of the VDS (400) can be changed by changing the P-code, reducing the need for burdensome engine updates. |

A data processing apparatus and method are provided for handling instructions to be executed by processing circuitry.

Maximized memory throughput using cooperative thread arrays
In parallel processing devices, for streaming computations, processing of each data element of the stream may not be computationally intensive and thus processing may take relatively small amounts of time to compute as compared to memory accesses times required to read the stream and write the results. Therefore, memory throughput often limits the performance of the streaming computation. Generally stated, provided are methods for achieving improved, optimized, or ultimately, maximized memory throughput in such memory-throughput-limited streaming computations. Streaming computation performance is maximized by improving the aggregate memory throughput across the plurality of processing elements and threads. High aggregate memory throughput is achieved by balancing processing loads between threads and groups of threads and a hardware memory interface coupled to the parallel processing devices. |

Retail transactions involving digital content in a digital rights management (DRM) system
A retailer facilitates issuance of a digital license from a licensor to a customer for a corresponding piece of digital content. The retailer receives payment for the license from the customer, where the payment is to be shared with the licensor in a pre-determined manner.

The need for dynamic optimization arises in many settings, as diverse as solar car power consumption during a multi-day race and retirement portfolio management. We disclose a reformulation of the control problem that overcomes the so-called “curse of dimensionality” and allows formulation of optimal control policies multiple period planning horizons. One optimal control policy is for power consumption by a solar car during a race, which involves many course segments, as course conditions vary through a day. Another is for risk in and consumption from a portfolio intended to support retirement. Both multi-period control policies take into account future uncertainty. Particular aspects of the present invention are described in the claims, specification and drawings. |

Automated transaction processing system and approach
Transaction processing is facilitated using an approach for automatically grouping transaction-based documents as a function of matching data in the documents. In one example embodiment of the present invention, data from selected attribute fields in transaction-based documents is parsed as the documents are received at a transaction processor. When data in selected attribute fields from two or more documents match, the transaction processor automatically groups the documents having matching data under a particular anchor identification code defined as a function of the match. Upon receipt of one or more other transaction-based documents, the transaction processor advances progress towards completion of the common transaction to which the documents apply. With this approach, predefined data (e.g., a purchase order number) need not necessarily be included with a particular transaction document in order to group the document with another document belonging to the same common transaction. |

Pseudo logs to improve stratigraphic correlation between sedimentary basins
In order to improve the tie between depositionally equivalent beds relative to two or more basins detected within a multi dimensional seismic volume of interest, pseudo logs based on the average of attributes derived from seismic impedance where the compaction trend is not present are created for each basin. The mean is taken over all available azimuths, following the structural variations of introduced micro layers. The correlation between the pseudo log relative to each basin enable a more reliable interpretation between the different basins from which sound exploration decision can be made. Such a process has been successfully applied to seismic data acquired in deep water environment. |

Determining document authenticity in a closed-loop process
A document authentication method uses a watermark added in a printed document to detection possible alterations made to the document after it was printed. First, a visible watermark in the form of a dot pattern is overlapped with an original digital image. The watermarked image is printed out as a halftone image at a first resolution. The watermark in the printed document appears as a light gray shade. Later, the printed document is scanned back using a grayscale scan at a resolution higher than the first resolution. In the scanned image, altered areas would appear flat (lacking intensity variation) whereas unaltered areas will have relatively large density variations due to the watermark dots and the fact that the image was halftone printed at a lower resolution. Alternations are detected by identifying flat areas within the image using a combination of flat block detection and a multiple thresholds method. |

Thus, coordination of admission control across multiple transport network domains is achieved, without a QoS signaller having to contact each individual domain. |
