20090202356 | VERTICAL AXIS ROTOR-TYPE WIND TURBINE - The invention refers to the field of wind power engineering, particularly to the vertical axis rotor-type wind turbines, which can be used for drive of electric generators or other using equipment of mechanical energy. The rotor-type wind turbine contains a central vertical shaft, mounted in a hollow elongated supporting column, and rotor structure, comprising two lattice-type blocks with power elements—the lattice-type stacks of aerodynamic blades. Each of the lattice-type blocks is carried by two corresponding lattice-type arms. When using the wind turbine two-block structure, the blocks are positioned by 180° to each other. The end parts of the aerodynamic lattice-type blades in blade blocks are fastened in relevant upper and lower shroud flanges. Each blade block forms the lattice and inter-blade channels so that the efficiency of utilization of the energy of the wind blowing along the inter-blade channels is determined as the sum of thermodynamic component and kinetic component of the factor of utilization kinetic energy of wind. Moreover, the design of vertical-axis wind turbine provided with lattice-type blade blocks and inter-blade channels ensure the rotation of the rotor under the impact of air flux even at low wind velocities. | 08-13-2009 |

20140214936 | IDENTIFYING SUBGRAPHS IN TRANSFORMED SOCIAL NETWORK GRAPHS - A graph of a social network is received. The graph may include a node for each user account and an edge between nodes that represent social networking relationships such as messages between the user accounts or a friend relationship. The graph is transformed into a transformed graph where nodes have direct edges depending on a local test among its neighbors in the original graph. Small subsets of the transformed graph are categorized. The categories are used to identify subgraphs in the transformed graph. Each subgraph is grown by adding an edge from the transformed graph to the subgraph depending on local tests among nodes associated with the edge that have at least one edge that is already in the subgraph. The categorized subgraphs are used to provide targeted advertising, suggest new connections, identify different personalities and interests of users, or to provide other services. | 07-31-2014 |

20110264639 | LEARNING DIVERSE RANKINGS OVER DOCUMENT COLLECTIONS - A document selector selects and ranks documents that are relevant to a query. The document selector executes an instance of a multi-armed bandits algorithm to select a document for each slot of a results page according to one or more strategies. The documents are selected in an order defined by the results page and documents selected for previous slots are used to guide the selection of a document for a current slot. If a document in a slot is subsequently selected, the strategy used to select the document is rewarded with positive feedback. When the uncertainty in an estimate of the utility of a strategy is less than the variation between documents associated with the strategy, the strategy is subdivided into multiple strategies. The document selector is able to “zoom in” on effective strategies and provide more relevant search results. | 10-27-2011 |

20130260352 | PROVIDING QUESTIONS TO ENTITY GROUPS - Entities that answer questions are organized into entity groups. An interface determines an answer to a question from one of the entity groups with a confidence that is greater than a second confidence threshold. To determine the answer, the interface performs an exploration phase where the interface asks the question to each of the entity groups. Entity groups that provide answers with a confidence that is greater than a first confidence threshold are selected for a subset. The interface enters an exploitation phase where the question is asked of the entity groups in the subset. If an answer is determined with a confidence that is greater than the second confidence threshold, then the answer is provided. If no answer is determined before a duration of time expires, then the interface enters a rollback phase where all of the entity groups are considered. | 10-03-2013 |
