20080270852 | MULTI-DIRECTIONAL FAULT DETECTION SYSTEM - An apparatus, program product and method checks for nodal faults in a group of nodes comprising a center node and all adjacent nodes. The center node concurrently communicates with the immediately adjacent nodes in three dimensions. The communications are analyzed to determine a presence of a faulty node or connection. | 10-30-2008 |
20080275683 | kD TREE AND ENVELOPE TO IMPROVE IDENTIFICATION OF NEAREST ATOMS - A method and apparatus for performing a molecular modeling simulation is disclosed. The simulation may be configured to store the position of atoms for a first and second molecule in a first and a second kd-tree. The simulation may also generate an envelope that contains all atoms of the second molecule, parse the kd-tree generated for the first molecule to identify atoms of the first molecule within the kd-tree of that are within the envelope. For each such atom, the simulation may search the kd-tree generated for the second molecule to identify corresponding nearest atom of the second molecule. | 11-06-2008 |
20080275685 | MISS-ACCUMULATION IN A BINARY SPACE PARTITIONING TREE - Embodiments of the invention provide a technique for improving the efficiency of a molecular modeling simulation. In one embodiment, the simulation may parse a kd-tree representing a receptor atom to identify atoms of the receptor within a specified distance of a target point. The target point may represent the center of a spherical envelope enclosing atoms of a ligand atom. A miss-accumulation vector may be used to accumulate a miss distance representing the minimum distance between a target point and a given node of the kd-tree. Thus, although the search algorithm may only evaluate the distance between the target point and a splitting dimension at each node of the kd-tree, the miss-accumulation vector may be used to account for distances over multiple dimensions. | 11-06-2008 |
20080275686 | ENVELOPE TECHNIQUE FOR EXCLUSION OF ATOMS IN AN HBOND CHECK - A technique for reducing the number of actions performed as part of a molecular modeling simulation is disclosed. For example, embodiments of the invention may be used to reduce the number of comparisons performed in a simulation of binding affinity between a first molecule (e.g., a protein receptor site) and a second molecule (e.g., a ligand). Because such a simulation is typically performed a very large number of times for even one particular first and second molecule, and is further performed for different combinations of first and second molecules, the effect of reducing the number of comparisons is leveraged and can provide a significant impact on overall simulation performance. | 11-06-2008 |

20090112805 | METHOD, SYSTEM, AND COMPUTER PROGRAM PRODUCT FOR IMPLEMENTING SEARCH QUERY PRIVACY - User privacy is protected by preventing certain unsafe search queries from being associated with the user when saved by a search engine. When an unsafe query is detected, the unsafe query is submitted to a proxy service, and the proxy service submits the query to a search engine preventing the query from being associated with the user. The user receives the search results from the proxy service. Query filtering only allows queries to be submitted directly to the search engine that do not provide personal information or information which may infer an undesirable trend when taken in aggregate with other submitted queries by that user. | 04-30-2009 |
