Abstract: Provided is a mesh data creation method allowing appropriate expression of population densities while making a balance between accuracy and granularity. In the mesh data creation method, when the number of samples in a region of reference mesh data with a predetermined size is not less than a threshold, divided mesh data is created by dividing the region of the reference mesh data. Namely, each portion with a high population density can be expressed by a fine region of mesh data and each portion with a low population density by a coarse region of mesh data. The above makes it feasible to prevent meshes from becoming too fine to ensure accuracy or, conversely, from becoming too coarse to maintain granularity, thereby resulting in failing to achieve a detailed grasp of population densities, and thus to achieve appropriate expression of population densities while making a balance between accuracy and granularity.

Abstract: Embodiments may include a consistency measurement component that utilizes memory-efficient sets (e.g., Bloom filters) assigned to different time periods for tracking when different write operations are performed on replicated data objects within a distributed data store. The consistency measurement component may evaluate whether read operations directed to the distributed data store are inconsistent. To do so, the consistency measurement component may determine, for a given read operation, the age of the value read from a given replicated data object (e.g., by evaluating a “last-modified” timestamp). The consistency measurement component may identify a memory-efficient set that includes the key of that replicated data object in order to determine when the replicated data object was last written to. If the age of the value read is older than the time at which the replicated data object was last written to, the consistency measurement component may determine that the read operation was inconsistent.

Abstract: Systems and methods for determining delivery hierarchical information for an Ad unit. In an example method performed at a server, location information is received from a user computer system via a network. The location information is associated with an Ad unit presented on a webpage accessed by the user computer system. The server determines if any previously stored signature information matches with at least a portion of the received location information, then extracts domain information for any portions of the received location information that matches with any previously stored signature information. Then, at least partial delivery hierarchical information is generated based on the extracted domain information. The process repeats for other location information associated with the Ad unit that is received at the server. The generated delivery hierarchical information is aggregated. Then a report is generated based on the aggregated delivery hierarchical information.

Abstract: According to one embodiment, an information collection apparatus includes an information collector, a database, a shift width estimator, and a collection controller. The collector collects time-series data from a start time with a period of collection. The database accumulates the time-series data. The shift width estimator detects a loss of data in the time-series data and estimates a shift width corresponding to a difference between a time the loss has occurred and a collection time of data of an outlier. The collection controller obtains a correction value of the start time and a correction value of the collection period to eliminate the shift width, and controls the collection of the time-series data.

Abstract: A pattern matching accelerator (PMA) for assisting software threads to find the presence and location of strings in an input data stream that match a given pattern. The patterns are defined using regular expressions that are compiled into a data structure comprised of rules subsequently processed by the PMA. The patterns to be searched in the input stream are defined by the user as a set of regular expressions. The patterns to be searched are grouped in pattern context sets. The sets of regular expressions which define the pattern context sets are compiled to generate a rules structure used by the PMA hardware. The rules are compiled before search run time and stored in main memory, in rule cache memory within the PMA or a combination thereof. For each input character, the PMA executes the search and returns the search results.

Abstract: A table-level histogram is maintained incrementally without requiring rescanning of the entire table when new data values are added to the table. A table has multiple partitions of data values. A histogram for data values of the partitions is generated. When a new partition of data values is added to the table, a histogram for only the new partition is generated. To generate a histogram for the entire table, the histograms for the previously generated and newly added partitions are used without needing to refer to the underlying data. A similar approach is applicable when modifying data values in a partition.

Abstract: Algorithms and concepts for maintaining uniform random samples of streaming data and stream joins. These algorithms and concepts are used in systems and methods, such as wireless sensor networks and methods for implementing such networks, that generate and handle such streaming data and/or stream joins. The algorithms and concepts directed to streaming data allow one or more sample reservoirs to change size during sampling. When multiple reservoirs are maintained, some of the algorithms and concepts periodically reallocate memory among the multiple reservoirs to effectively utilize limited memory. The algorithms and concepts directed to stream joins allow reservoir sampling to proceed as a function of the probability of a join sampling operation. In memory limited situations wherein memory contains the sample reservoir and a join buffer, some of the stream join algorithms and concepts progressively increase the size of the sampling reservoir and reallocate memory from the join buffer to the reservoir.

Grouping expressions are used to group nodes and consolidate costs by various procedures when making modified sample stacks: clustering-by-name, entry-group-clustering, folding-by-name, a folding-by-cost. An entry group clustering shows at least one entry point name while avoiding unwanted detail.
