Title: Methods and compositions for extinguishing fires using aqueous gelled fluids
Inventor: TAYLOR ROBERT S
IPC: A62D1/00
Filed: 2004-09-20
Granted: 2006-10-24
Abstract: The present invention relates to improved methods of extinguishing fires or retarding fire propagation by forming a crosslinked water gel which is then applied to the fire or area to be protected. By forming a semi-solid crosslinked gel water can be conveyed over large distances while minimizing losses due to misting, thus making fire fighting from great distances possible and improving the efficiency of aerial drops. The crosslinked gel also has a particularly good adhesiveness and cohesiveness, giving it the ability to form one continuous blanket on the ground thereby smothering the fire and preventing re-ignition. The combination of these properties makes the crosslinked gel ideal for applications such as control and extinguishing of forest fires. In addition, the composition may include additional active ingredients such as herbicide, pesticide, fungicide fertilizer, or the like for soil remediation after the fire is extinguished.

Title: Information retrieval and text mining using distributed latent semantic indexing
Inventor: BEHRENS CLIFFORD A
IPC: G06F7/00
Filed: 2004-04-23
Granted: 2011-09-27
Abstract: The use of latent semantic indexing (LSI) for information retrieval and text mining operations is adapted to work on large heterogeneous data sets by first partitioning the data set into a number of smaller partitions having similar concept domains. A similarity graph network is generated in order to expose links between concept domains which are then exploited in determining which domains to query as well as in expanding the query vector. LSI is performed on those partitioned data sets most likely to contain information related to the user query or text mining operation. In this manner LSI can be applied to datasets that heretofore presented scalability problems. Additionally, the computation of the singular value decomposition of the term-by-document matrix can be accomplished at various distributed computers increasing the robustness of the retrieval and text mining system while decreasing search times.
