20150156012 | METHOD FOR DEFENSE AGAINST PRIMARY USER EMULATION ATTACKS IN COGNITIVE RADIO NETWORKS USING ADVANCED ENCRYPTION - A method for defense against primary user emulation attacks in cognitive radio networks includes the steps of generating an advanced encryption standard (AES)-encrypted reference signal with a transmitter for transmitting to at least one receiver. The method also includes the steps of allowing a shared secret between the transmitter and the at least one receiver and regenerating the reference signal at the at least one receiver and using the regenerated reference signal to achieve accurate identification of authorized primary users as well as malicious users. | 06-04-2015 |

20130080133 | CORE-PLUG TO GIGA-CELLS LITHOLOGICAL MODELING - Well core data descriptions are received as input digital data for computer lithofacies modeling. Digital templates are established for carbonate and clastic core description based on reservoir rock formation analysis. Description criteria of the template for carbonate rock can include texture, mineral composition, grain size, and pore type. For clastic rock, the criteria in the template can include grain size, sedimentary structure, lithology, and visual porosity. The data and observations regarding these criteria are entered into a computer 3D geological modeling system directly. Wireline log data are integrated to calibrate with well core description to derive lithofacies. The lithofacies are exported in digital format to be entered into the 3D geological modeling system. A geologically realistic model of the reservoir can be established. | 03-28-2013 |

20130339355 | CLUSTERING STREAMING GRAPHS - A system for clustering vertices in a streaming graph includes a structural sampler configured to receive a stream of edges. The structural sampler includes a reservoir manager configured to receive the stream of edges and create a structural reservoir and a support reservoir and a graph manager configured to receive the structural reservoir from the reservoir manager and to create a sampled graph from the structural reservoir, wherein the sampled graph includes one or more clusters that each include one or more connected vertices. | 12-19-2013 |
20130339357 | CLUSTERING STREAMING GRAPHS - Embodiments of the invention include methods for identifying one or more clusters in a streaming graph, the method includes receiving a stream of edges and sampling the stream of edges to create a structural reservoir and support reservoir. The method also includes creating a sampled graph from the structural reservoir and identifying the one or more clusters in the sampled graph by grouping one or more connected vertices in the sampled graph. | 12-19-2013 |
