  • Publication number: 20240347052
    Abstract: Disclosed is a system and method for determining an intent of a user from an utterance of the user. The system initially builds an intent determination model using a plurality of sample utterances, each assigned with at least one intent class. That is, on receiving the sample utterances, the system extracts significant word pairs from each sample utterance, computes a distinction factor of each significant word pairs, computes a Positive Probability and a Negative Probability for each significant word pairs, and generates the intent determination model by storing each significant word pairs and its distinction factor, the Positive Probability and the Negative Probability. Then on receiving any new utterance, the system extracts significant word pairs, identifies one or more matching word pairs in the model and determines the intent of based on the distinction factor, Positive Probability, and the Negative Probability of the one or more matched word pairs.

  • Patent number: 7597237
    Abstract: A process is disclosed that creates a high shear rate in a workpiece using a head including a ring-shaped rotatable shoulder, a first pin and a second pin, both pins extending downwardly relative to the shoulder. The process includes coupling the workpiece to a table and rotating the first pin and the second pin in the same direction, wherein the first pin has a diameter, wherein a gap between the first pin and the second pin is less than the diameter. The head is plowed through the workpiece with the shoulder bearing downwardly against the workpiece and the first and second pin disposed in the first and second workpieces. The first pin rotates in a direction opposite the direction of the second pin in the gap to create a high shear rate of the workpiece within the gap.

  • Publication number: 20080000557
    Abstract: A method and apparatus for producing ultra-fine grained magnesium metal alloy material sheets. The apparatus molds and rapidly solidifies a metal alloy material to form a fine grain precursor. The precursor is then subjected to deformation strains that alter the grain structure of the precursor so as to form a ultra fine grained structure in sheet form. The sheet form may then be subjected to superplastic forming to form a net shaped article.

  • Publication number: 20060283529
    Abstract: A method and apparatus for producing ultra-fine grained metal material sheets. The apparatus molds and rapidly solidifies a metal material to form a fine grain precursor. The precursor is then subjected to a series of successive alternating tensile and compressive strains that alter the grain structure of the precursor so as to form a ultra fine grained structure in sheet form. The sheet form may then be subjected to superplastic forming to form a net shaped article.

  • Publication number: 20060218030
    Abstract: Work item rules for a work item tracking system are provided. Work item rules may be accessible, usable and subject to interpretation by multiple software entities. Further, work item rules may be configured to be subject to creation and change by users, for example, by exposure to users through a user interface. A work item rule may specify an identifier by which the abstraction can be identified and/or a name, and may specify, or be indicative of, a condition and an action to be taken if the condition is satisfied. In response to a first user action affecting a first work item rule, one or more work item rules corresponding to the first user and/or the first work item may be determined. The one or more work item rules then may be interpreted, and the user action responded to based on the interpretation.

  • Publication number: 20060123432
    Abstract: Techniques for enabling inter-subsystem resource sharing are provided. The techniques include providing an RPC client on a first subsystem for acting as a proxy for a resource of a second subsystem. When the first subsystem receives a request from an application to access the resource, the RPC client may invoke a function of an RPC server associated with the second subsystem. The RPC server may load the resource on the second subsystem. The RPC client may then act as a proxy for the resource.
