Abstract: An annular support for a vane assembly including a vane having an aerofoil section with a radially inner base and a radially outer tip is provided. The annular support has a gas path surface which, in use, faces an annular gas path. In some aspects, the annular support is locally thickened by a projection extending radially from the gas path surface, the projection at least partly defining the perimeter of an aperture for receiving the base or tip of the aerofoil section. In some aspects, there is a liner lining the aperture and the liner extends from the aperture beyond the gas path surface.

Abstract: A method and system for performing data analysis where multiple, categorical dimensions and statistical measures are used. The method includes preparing multi-dimensional data into nodes and arranging them logically in the form of a partial-order database. The database may then be traversed by a data-mining tool, or queried in an OLAP manner. Queries are answered through a process of associative partial-order search, which includes optional support for “children-of” requests, and optional support for fuzzy pattern-matching. By aggregating measures on-the-fly, this method is able to preform well without requiring a large number of summary nodes, when taken as a percentage of the total node count.
