A signal processor receives settings information. The settings information specifies a setting of a given element for each image in a sequence of multiple images in which the given element resides. The signal processor also receives precision metadata specifying an estimated precision of each of the settings of the given element for each image in the sequence. Based on the settings information and the precision metadata, the signal processor generates a setting value for the given element. If the setting value produced for the given element is relatively stable, and thus likely a better representation of a setting for the given element than a current setting of the given element, the signal processor utilizes the generated setting value instead of the current setting for encoding purposes.

In HEVC (High Efficiency Video Coding), a 2N×2N coding unit can be partitioned into various partition types hierarchically. The coding system uses a criterion to determine the best partition, where RD-rate is often used as the criterion. N×N partition at level k becomes redundant if 2N×2N at level k+1 will be evaluated. In order to eliminate the above redundancy, the allowable partition sizes are constrained according to a method previously disclosed. In the current invention, the complexity is further reduced. According to one embodiment, N×N partition is not allowed for any INTER mode regardless of the coding unit size. Furthermore, flexibility is provided so that either the method and apparatus with further complexity reduction can be selected or an alternative method and apparatus can be selected.

The threat detection system sends trusted identifiers when the received links are identified in the whitelist and sends block identifiers back to the web browsers when the received links are identified in the blacklist. The trusted identifiers cause the web browsers to display a trusted message and the block identifiers cause the web browsers to remove the received link and display a warning message. The threat detection system may receive threat reports for suspected links from employees of a same enterprise and allow an enterprise security administrator to asynchronously update the blacklists and whitelists based on the threat reports received from the enterprise users.

A network browser has a Malware detection manager for direct or indirect scanning of files during an upload or download processes for viruses, adware, spyware, etc. The malware detection manager defines and employs a quarantine bin, which is an isolated and secure memory space or directory for temporary placement of file packets during the file transmission while malware detection can commence. The malware detection manager scans for malware code associated with the packet sequence encountered during a file transmission to and from the Internet, during which it quarantines all the scanned packets in the quarantine bin. Quarantined files can be released if there is a human challenge authorizing the release of the file. Exchanging a Malware free signature between server and client via a trusted download center may be done so the client device need not scan the files for malware if content is certified and guaranteed as malware-free.

When a battery is supported on a cooling plate, since a heat transfer sheet, which is deformable by pressure, is held between the cooling plate and a cooling surface of the battery, it is possible to efficiently transfer the heat of the battery from the cooling surface to the cooling plate via the heat transfer sheet, thereby enhancing the effect in cooling the battery.

In a computing system running an environment for designing operation of circuity, at least the following are performed for providing simulations and evaluations of one or more user-defined modules of circuitry including one or more pipeline stages in a pipeline. A model of the pipeline is automatically generated by using a pipeline block diagram, where the model is generated in a high-level modeling language able to perform simulations of circuitry with the pipeline. An interface is automatically generated between the one or more user-defined modules and the generated model of the pipeline, the interface including a set of access methods to the pipeline. Evaluation is performed of the one or more user-defined modules using the automatically generated model of the pipeline and the automatically generated interface. Methods, apparatus, and computer program products are disclosed.

Described are techniques for performing data storage optimizations. A reserved workload for a first of a plurality of storage tiers is determined. Each of the plurality of storage tiers is characterized by a set of one or more attributes. The first storage tier includes performance characteristics which are any of incomplete, unknown, and unable to be predictively modeled for various workloads. The plurality of storage tiers includes the first tier and a remaining set of additional storage tier(s). Performance is modeled of a first workload distributed among the remaining set of storage tiers. The first workload represents a total workload less the reserved workload. One or more data movements are determined in accordance with the modeling. Each data movement moves a data portion from a first physical device of one of the plurality of storage tiers to a second physical device of another of the plurality of storage tiers.

Systems, methods, and computer media for identifying related strings for search query rewriting are provided. Session data for a user search query session in an accessed click log data is identified. It is determined whether a first additional search query in the session data is related to a first user search query based on at least one of: dwell time; a number of search result links clicked on; and similarity between web page titles or uniform resource locators (URLs). When related, the first additional search query is incorporated into a list of strings related to the first user search query. One or more supplemental strings that are related to the first user search query are also identified. The identified supplemental strings are also included in the list of strings related to the first user search query.

Methods and systems for validating online certificate status are provided. A method for validating online certificate status may include storing data associated with a first certificate beyond an expiration time of a second certificate. The second certificate was used to validate the first certificate. The method may further include validating the first certificate upon a host connection request or prior to expiration of a second certificate. A system for validating online certificate status may include a certificate data acquirer and a certificate validator. Another method for validating online certificate status may include obtaining a hostname and selecting a first certificate based upon an association between the hostname and data associated with the first certificate. The method may also include providing the first certificate data for validation. A system for validating online certificate status may include a speculator. A system for providing an online certificate status may include a speculative server.

One embodiment of the present invention provides a system that merges similar clusters of conceptually-related words in a probabilistic generative model for textual documents. During operation, the system receives a current model, which contains terminal nodes representing random variables for words and contains cluster nodes representing clusters of conceptually related words. Nodes in the current model are coupled together by weighted links, wherein if a node fires, a link from the node to another node causes the other node to fire with a probability proportionate to the weight of the link. Next, the system determines whether cluster nodes in the current model explain other cluster nodes in the current model. If two cluster nodes explain each other, the system merges the two cluster nodes to form a combined cluster node.
