Shifting means successively shifts the optical path of the image scene relative to the masking filter, by a shifting increment or fill-factor reduction amount equal to a fraction of the array pixel width, to image different sub-pixel regions in each imaging sample. A processor reconstructs an image frame having a resolution greater than the intrinsic detector resolution by the fill-factor reduction amount.

If the first set is similar to the reference set, and if the execution of the algorithm corresponding to the reference set is restricted by one or more computer system polices, one or more operations limiting the execution of the restricted algorithm are performed, thus ensuring conformance with the computer system policies.

A call to a memory management application programming interface (API) that results in a buffer overflow due to inaccurate bounds checking could potentially leave the system vulnerable to being exploited by a third party. Approaches presented herein can monitor calls to these APIs in order to determine typical memory sizes passed to these APIs. During an initial baselining period a number of profiles are generated that indicate expected memory size parameters under various different call conditions, such from specific sources or call stacks. Comparing subsequently received API calls against the expected values from the relevant profile enables the legitimacy of an API call to be determined with relatively high accuracy. A suspicious call is identified based at least in part upon determining that the memory size of the call falls outside an expected range for that API and the relevant context.

Described herein is a method of designing micro-fluidic devices. A target cost function based on device design parameters is chosen. The performance of one or more design candidates is run in a simulation model. A design candidate with a cost function closest to the target cost function is chosen and modified in an optimization routine to provide a modified design candidate having modified device design parameters. The cost function for the modified initial design candidate is computed, and when the modified design candidate has a computed cost function that meets the target cost function, optimized device design parameters of an optimized device design are obtained. Additional optimization iterations may be performed as needed to arrive at an optimized device design. A micro-fluidic device based on the optimized device design is manufactured.

The embodiments herein discloses a system and method for designing SoC by synchronizing a hierarchy of SMDPs. Reinforcement Learning is done either hierarchically in several steps or in a single-step comprising environment, tasks, agents and experiments, to have access to SoC (System on a Chip) related information. The AI agent is configured to learn from the interaction and plan the implementation of a SoC circuit design. Q values generated for each domain and sub domain are stored in a hierarchical SMDP structure in a form of SMDP Q table in a big data database. An optimal chip architecture corresponding to a maximum Q value of a top level in the SMDP Q table is acquired and stored in a database for learning and inference. Desired SoC configuration is optimized and generated based on the optimal chip architecture and the generated chip specific graph library.

A static timing analysis method and apparatus that determine an expected design condition surrounding a target cell in an integrated circuit design. A derate adjustment is determined based on the expected design condition for a target cell and a timing derate, representing variation in propagation delay for a default design condition, is then adjusted based on the derate adjustment. An expected timing of a signal path including the target cell is determined based on the adjusted timing derate. The derate adjustment may be determined based on simulated variance of the propagation delay through the target cell for the expected design condition. This approach avoids unnecessary optimism or pessimism in the timing derate, which reduces the number of false positive or false negative detections of timing violations in the static timing analysis.

An approach is provided dynamically prioritizing question requests based on extracted question data. In the approach, performed by an information handling system, a number of question requests to a question and answering (QA) system are received from a computer network, and a plurality of question priority parameters are identified, including one or more question topics and a plurality question context parameters, by performing natural language processing (NLP) analysis of each question request. The approach determines a target priority value for each question request based on the plurality of question priority parameters identified for said question request. By evaluating the target priority values for the plurality of question requests, processing of the question requests is prioritized by applying an artificial intelligence (AI) learned models and rule-based logic at the information handling system to evaluate the target priority values for the plurality of question requests.

Innovations for category-prefixed data batching (“CPDB”) of entropy-coded data or other payload data for coded media data, as well as innovations for corresponding recovery of the entropy-coded data (or other payload data) formatted with CPDB. The CPDB can be used in conjunction with coding/decoding for video content, image content, audio content or another type of content. For example, after receiving coded media data in multiple categories from encoding units, a formatting tool formats payload data with CPDB, generating a batch prefix for a batch of the CPDB-formatted payload data. The batch prefix includes a category identifier and a data quantity indicator. The formatting tool outputs the CPDB-formatted payload data to a bitstream. At the decoder side, a formatting tool receives the CPDB-formatted payload data in a bitstream, recovers the payload data from the CPDB-formatted payload data, and outputs the payload data (e.g., to decoding units).

The consistency of a data structure is maintained where changes in the form of atomic operations are requested by more than one user to an object graph containing a plurality of objects. Operational transformations specifying how one atomic operation is transformed against another one are accessed and the object graph is modified with the first and second set of changes by employing the operational transformations on the atomic operations and applying the resulting transformed operations to the object graph. The transformed operations are recorded in a history log. The atomic operations are object operations that create or delete an object of the object graph and/or property operations changing a property of an object. Each operation retains the identifier of the object it acts on and information on each change of the object resulting from the operation. Multi-operation conflicts are resolved by defined conflict resolution events.

Various technologies described herein pertain to classifying data in a main memory database system. A record access log can include a sequence of record access observations logged over a time period from a beginning time to an end time. Each of the record access observations can include a respective record ID and read timestamp. The record access log can be scanned in reverse from the end time towards the beginning time. Further, access frequency estimate data for records corresponding to record IDs read from the record access log can be calculated. The access frequency estimate data can include respective upper bounds and respective lower bounds of access frequency estimates for each of the records. Moreover, the records can be classified based on the respective upper bounds and the respective lower bounds of the access frequency estimates, such that K records can be classified as being frequently accessed records.

A row is inserted in a database table on a page having a first space reserved for inserting rows of the database table. A second space is reserved for adding data to the inserted row, wherein reserving the second space includes reserving the second space on the page responsive to inserting the row, so that the amount of space reserved for adding data to inserted rows grows as more rows are inserted. The page is marked full for the second space independently of whether the first space is full for inserting new rows. Data is added to rows on the page, responsive to detecting that the second space is full, by adding the data to one or more new pages, even though rows may still be inserted on the page using any remaining room in the first space on the page.
