  • Publication number: 20150169584
    Abstract: A system, computer-readable storage medium storing at least one program, and a computer-implemented method for re-ranking ranked search results is presented. Ranked search results satisfying a search query are obtained, where the ranked search results include a first search result corresponding to a first document associated with a first entity and a second search result corresponding to a second document associated with a second entity, and where the first search result is ranked higher than the second search result. The first document and the second document are determined to satisfy a similarity criterion. The second entity is determined to satisfy a predefined authorship differential with respect to the first entity. Responsive to determining that the second entity satisfies the predefined authorship differential with respect to the first entity, the second search result and the first search result in the ranked search results are swapped to produce re-ranked search results.

  • Patent number: 7751714
    Abstract: A Centralized Resource Management (CRM) system that supports the sharing of all the transponders in a WXC node, i.e., any spare transponder can be reconfigured to accommodate any drop channel, regardless of wavelength or input port. Consequently, network restoration in case of network failures is supported as well as the ability to reconfigure as a result of dynamic traffic requirements in the network. CRM advantageously is applied to conventional WXC node as well as WSS-based WXC nodes in the WDM networks. Three CTM schemes which manage the transponders in the WSS-based WXC node are described along with reconfiguration algorithms for an optical switchless CRM solution.

  • Patent number: 7453274
    Abstract: One embodiment relates to a method for detecting defects in circuitry formed on a semiconductor substrate. A first scan of said circuitry is performed by scanning a primary electron beam in a first scan direction relative to said circuitry, and secondary electrons emitted during the first scan are detected so as to form a first voltage-contrast image. A second scan of said circuitry is performed by scanning the primary electron beam in a second scan direction relative to said circuitry, and secondary electrons emitted during the second scan are detected so as to form a second voltage-contrast image. The second scan direction is non-parallel to the first scan direction. The first and second voltage-contrast images are then compared to detect electrically-active defects. Other embodiments, aspects and features are also disclosed.

  • Patent number: 5966625
    Abstract: A single crystal silicon wafer is sliced off so as to have a slant surface that is inclined from plane (001) such that the normal of the slant surface is inclined by 0.01.degree. to 0.2.degree. from direction [001] toward direction [110]. After being cleaned, the silicon wafer is heat-treated at 600-1,300.degree. C. for not less than 1 minute in an ultrapure argon or hydrogen atmosphere containing nitrogen at not more than 0.1 ppm, to thereby cause the slant surface to have a stepped crystal surface structure. The stepped crystal surface structure is constituted of step walls Sa and Sb when it has been formed by a heat treatment in an argon atmosphere, and substantially all of its step walls are of a type Sb when it has been formed by a heat treatment in a hydrogen atmosphere.

  • Patent number: 5794737
    Abstract: An elevator drive machine includes a speed reduction unit, a driving sheave, and the first and the second driven sheaves formed over the driving sheave and arranged a triangle with the driving sheave. Each of the sheave has ratchet on its periphery, a pawl mechanism is mounted near the sheave. A speed limiter which includes a centrifugal speed limiter engaging with the gear of the first driven sheave and a three-branch lever, is provided on the side of driving sheave and the first driven sheave, When the dropping speed of the cab overruns the given speed, the three-branch lever moves so as to make the ratchet engage with the pawl, thus braking the driving sheave and the first driven sheave, quickly increasing the friction force of driving rope and immediately stopping the cab. It can prevent the rope from sliding on the sheaves, and has advantages of compact construction and low cost.
