  • Publication number: 20110270557
    Abstract: A method for measuring critical current density of superconductor wires according to the present invention is characterized in that it includes: (a) applying an external magnetic field to the superconductor wires, (b) measuring a magnetization loss of the superconductor wires according to the application of the external magnetic field, (c) normalizing the measured magnetization loss, and then calculating a fully-penetration magnetic field of the superconductor wires according to the normalized magnetization loss, (d) calculating a critical current density of the superconductor wires according to the calculated fully-penetration magnetic field.

  • Patent number: 8050894
    Abstract: Space frames consist of combination of one or more basic modules to function as a decorative feature or a building element in architectural design. There are certain aesthetic criteria to meet on the design of a basic space frame module; space frame module, geometric regularity, and dimension regularity for all the angles and lengths between edges. Designers exercise their own creativity to develop space frame modules base on these criteria. The present invention relates to a hybrid algorithm based on evolutionary algorithm for graph encoding scheme (EAGES) and genetic algorithm (GA) to evolve the design automatically in relative small number of generations. The hybrid algorithm is a tool to architects and designers to rapidly produce aesthetically pleasing designs with the resources available to them.

  • Patent number: 8005209
    Abstract: Advanced Encryption Standard (AES) is an encryption algorithm for securing sensitive unclassified material by U.S. Government agencies and, as a consequence the de facto encryption standard for commercial applications worldwide. Performing concurrent error detection (CED) for protection of such a widely deployed algorithm is an issue of paramount importance. We present a low-cost CED method for AES. In this method, we make use of invariance properties of AES to detect errors. For the first time, the invariance properties of the AES, which are for the most part used to attack the algorithm, are being used to protect it from fault attacks. Our preliminary ASIC synthesis of this architecture resulted in an area overhead of 13.8% and a throughput degradation of 16.67%.

  • Patent number: RE42600
    Abstract: A pipeline-based matching scheduling approach for input-buffered switches relaxes the timing constraint for arbitration with matching schemes, such as CRRD and CMSD. In the new approach, arbitration may operate in a pipelined manner. Each sub-scheduler is allowed to take more than one time slot for its matching. Every time slot, one of them provides a matching result(s). The sub-scheduler can use a matching scheme such as CRRD and CMSD.
