Abstract: A system that facilitates performance of a focused search over a collection of sites comprises a subweb that corresponds to a topic and/or user characteristic(s) that are of interest to the user. The subweb includes a plurality of domains and/or paths (e.g. sites) that are related to the topic and/or the user characteristic(s). Each of the sites within the subweb is assigned a weight that indicates relevance of the site to the desirable topic and/or user characteristic(s). A search engine employs the subweb to facilitate focusing a search over a collection of sites. The search engine receives a query, and utilizes the subweb to focus a search over the selection of sites corresponding to the topic and/or user characteristic(s) represented by the subweb. The results from the search are returned to the user based at least in part upon the relevance weights assigned to the sites within the subweb.

Abstract: In an aircraft engine at the low-pressure compressor (5) level, imbalance effects may occur. In order to increase the rigidity of the set and therefore decrease potential cracks due to accidental imbalance, stiffeners (20) are suggested, which can be integrated by one of their extremities (22) to the crankcase (7) at the level of the structural arm (10) and at the other extremity (32) to the compressor (5) ideally at the level of the upper face of the third rectifier (RD3). An additional advantage is that the stiffeners are joined to each other in two places; their construction is optimized to limit the additional weight due to their presence.

Abstract: An adaptive data stream filter removes narrowband interference from the CATV  return path prior to these paths being combined in the network. A method for removing narrowband interference from the CATV return path detects potential narrowband interference in real-time and adapts a filter to remove this potential narrowband interference. An exemplary embodiment of the above method uses previously created filters that are combined based on detected interference in an adaptive manner to continually adapt to new interference sources. Another exemplary embodiment of the above method calculates new filter coefficients for the data stream filter based on detected interference.  In another embodiment, two filters are operated in a ping-pong manner for each band of interference identified as above threshold. This enables updating of one filter while another filter is performing the data stream filter operation.
