Abstract: A network correlation engine (CE-1) to be coupled to a telecommunication network (NT) comprising at least one network section (Sm) to supply at least one event notification (Am) upon detection of an event relating to the section. The correlation engine comprises at least one event analysis block (Bn) comprising at least a root cause analysis module (RCn) to receive on input the event notification and to supply on output a root cause analysis result (RRn) and a service analysis module (SAn) to receive on input the root cause analysis result from the root cause analysis module of the block is and to supply on output a service impact analysis result (SRn).

Abstract: A booster compressor includes inlet guide vanes supported from a shroud. A shell surrounds the shroud and defines a manifold. A splitter nose includes a groove receiving a forward tang of the shroud with a clearance therebetween defining an outlet for the manifold. Hot air is channeled through the manifold and out the splitter nose for deicing thereof.

Abstract: The invention relates to a therapeutic composition containing, as the active principle, .alpha.-linolenic acid and an alcohol of vegetable origin, such as a tocopherol or sitosterol. Preferably, the composition contains other fatty acids and is an organic extract of plants, especially of the Resedaceae family.The invention also relates to the plant extracts as novel products.The therapeutic composition is especially useful as an antiinflammatory.

Abstract: An inflatable structural member and a structure employing such inflatable members. The structural members each comprise an inner, air-impermeable inflatable tube made from an inexpensive, extruded, thermoplastic material; and an outer flexible sheath restraining the inner tube when it is inflated. The sheath is also constructed to shape the tube to a desired curved shape.
