Abstract: A method for topic discovery through structural knowledge in an associative document tree building system includes inserting a set of documents into nodes of a document tree, extracting a tag set of tags from the set of documents and inserting each tag into a different node of a tag tree. The method also includes conducting a search engine query using the tags of the extracted tag set to produce a new set of documents and inserting the new set of documents into nodes of the document tree. The method yet further includes extracting a new tag set of tags from the new set of documents and inserting each tag of the new tag set into a different node of the tag tree. Finally, the method includes displaying at least a portion of each of the document tree and tag tree in a user interface displayed.

Abstract: Discontinuous diamond particulate containing metal matrix composites of high thermal conductivity and methods for producing these composites are provided. The manufacturing method includes producing a thin reaction formed and diffusion bonded functionally graded interactive SiC surface layer on diamond particles. The interactive surface converted SiC coated diamond particles are then disposed into a mold and between the particles and permitted to rapidly solidify under pressure. The surface conversion interactive SiC coating on the diamond particles achieves minimal interface thermal resistance with the metal matrix which translates into good mechanical strength and stiffness of the composites and facilitates near theoretical thermal conductivity levels to be attained in the composite. Secondary working of the diamond metal composite can be performed for producing thin sheet product.

Abstract: A method of material treatment in which the surface of a metal substrate is converted to a composite structure of the metal and its nitride or carbide utilizing a high temperature chemically active thermal plasma stream, and the product obtained from that method. The complex thermal plasma contains controllable additions of active gas, liquid or solid substances. The surface layer obtained is functionally graded to the substrate resulting in an excellent bond that resists delamination and spalling, and provides a significant increase in hardness, wear and erosion resistance, and corrosion resistance, and a decrease in coefficient of friction.

Abstract: Systems and methods for authenticating subscribers of video signals are disclosed. In accordance with the various embodiments, a subscriber authentication system includes an encoder coupled to a source of video signals and a source of subscriber data. The encoder generates encoded video signals having at least a portion of the subscriber data encoded in the video signals. An authentication indicating apparatus operable to receive the encoded video signals and to decode the received signals generates an authentication status for the subscriber.
