Abstract: A system for parallel flow-awared pattern matching and a method thereof for performing distributed detection for incoming flows are provided. The system includes a pattern-set-partitioner for partitioning a pattern set for pattern matching into a number of pattern subsets in advance, a plurality of pattern matching engines, and a scheduler. The pattern matching engines each perform pattern matching for the incoming flows. The scheduler selects a number of pattern matching engines equal to the number of the partitioned pattern subsets from all the pattern matching engines and allocates pattern matching tasks, each performing flow matching against one pattern subset, to the selected pattern matching engines. With the system and method of the present invention, distributed detection can be performed by partitioning rules/pattern set to realize load-balancing parallel flow-awared pattern matching.

The method includes: searching the tree structure to reach a target node that can be associated with the key without acquiring a lock on the root node and on an internal node; setting the target node as a current node when the target node is a leaf node; moving the search to a node at a lower layer when the target node is an internal node by tracing an edge in the tree structure to reach a leaf node and setting the leaf node as the current node; and associating the key with the leaf node specified as the current node by acquiring a lock on the leaf node specified as the current node, thereby accessing the data.

Abstract: A mapping language, insertable into a DTD, allows automatic mapping from data sources into XML. A mapping results from the establishment of a correspondence between entities in a data source on the one hand and lists and scalars on the other hand. The language maps the lists and scalars to XML elements and attributes. The mapping language includes two constructs: the binding specification and the value specification. The value specification associates with a value or choice declaration. The binding specification includes at least one variable/expression pair. The constructs are insertable into a DTD to create an annotated DTD.

Abstract: A system and method for rapidly transmitting a large volume of e-mails. Based on domain names obtained from destination mailing addresses, a server 10 for a sender sorts e-mails to be transmitted, generates transfer data for each domain name by grouping e-mail data, and uses FTP to transmit the transfer data to servers 30 for distributors whose domain names correspond to those for which the transfer data were generated. At this time, compression is effective for improving the transmission of the transfer data. The server 30, upon receiving transfer data, analyzes the received transfer data to obtain the data for individual e-mails, and distributes the e-mail data to the mail boxes of individual recipients.

The inductor includes a separate isolated secondary coil, a set of transistors composing a closed loop with the secondary coil, a magnetic coupling between the primary coil of the LC VCO and the secondary coil, an electrical coupling between the LC VCO and the set of transistors composing a closed loop with the secondary coil, and means for electric current injection into the closed loop. Such an inductor can be tuned by modulating a mutual inductance, which is magnetically and electrically coupled with the LC VCO by injection of an electric current (I0).

Abstract: Methods and apparatus for detecting L-bit sync words occurring at N-bit intervals in PPM-encoded servo pattern read signals read in magnetic tape drives. A soft output detector processes the PPM-encoded servo pattern read signal to produce a series of soft output samples corresponding to respective bits encoded in the servo pattern. A sync word detector then produces block correlation values for respective positions of a sliding L-sample block in the series of soft output samples by (i) calculating at each block position bit correlation values indicating correlation between respective samples and corresponding bits of the sync word and (ii) summing each bit correlation value minus a predetermined function of the corresponding sample value. The sync word detector then detects a sync word at the block position with the maximum block correlation value in an (N+L?1)-sample sequence of the series of soft output samples.

Abstract: The present invention relates to a method of reducing the wear of a tip of a probe when the tip is in contact with a surface of a substrate and when the probe is mounted on a support structure. A method is provided where a load force is applied to the probe, thereby causing the tip to be maintained substantially in contact with the substrate surface and a modulation step where the e magnitude of the load force is modulated at a modulation frequency. The modulation frequency is selected to be greater than a fundamental vibration frequency of the support structure on which the probe is mounted.

Abstract: A method for the fabrication of a semiconductor structure that includes areas that have different crystalline orientation and semiconductor structure formed thereby. The disclosed method allows fabrication of a semiconductor structure that has areas of different semiconducting materials. The method employs templated crystal growth using a Vapor-Liquid-Solid (VLS) growth process. A silicon semiconductor substrate having a first crystal orientation direction is etched to have an array of holes into its surface. A separation layer is formed on the inner surface of the hole for appropriate applications. A growth catalyst is placed at the bottom of the hole and a VLS crystal growth process is initiated to form a nanowire. The resultant nanowire crystal has a second different crystal orientation which is templated by the geometry of the hole.

Abstract: A method and apparatus for optimizing information-retrieval related system performance based on users' communication relationships. Users' interactions and relationships with each other are tracked by a ‘relationship analyzer’ that queries multiple heterogeneous information sources, such as e-mail logs, organization charts, calendar entries, phone logs, etc. A data structure is created for each user reflecting the intensity of communication relationship with other users, and modified over time as the data in the information sources change. A relationship group is defined based on the data structure and preference or importance ratings for each type of communication relationship that includes each user's group of highest-priority other users. A derived relationship group may also be defined based on high-priority users of a user's highest-intensity relationships.

Abstract: The invention identifies areas in a workflow graph that operate on one workstation—islands that can execute also remote from a central workflow server. Such a remote workstation can even operate physically disconnected from a central server during the interpretation/execution of the island. The workflow model is analyzed and those parts that are defined for execution on one specific workstation are encapsulated. Those parts, called “islands” can be interpreted or executed on the central workflow server, or can be downloaded from the server to a specific remote client workstation. Additionally, the islands in the workflow graph can optionally be transformed, either at the server or after downloading at the destination workstations, towards much more efficiently executable versions of the islands.

Abstract: The invention comprises a counter virus agent for detecting viral infection of a computer system. The agent identifies potential host files for the agent within the computer system; and controls replication of the agent within the host files to maintain the agent at a pre-determined population level. When instantiated within one of the host files, the agent determines the population level of the agent within the computer system; and, responsive to the population level exceeding the pre-determined population level, indicates possible viral infection of the computer system.
