Abstract: A method is provided for classifying a maintenance record for a machine. The method includes receiving the maintenance record including maintenance event information expressed as a collection of terms of interest, and normalizing the terms of interest to their non-abbreviated, dictionary form. The method includes accessing a database of authoritative engineering information from electronic documents, expressed textually and indexed by class of a plurality of classes. The method includes weighted scoring the authoritative engineering information that uses one or more of the terms of interest represented in the weighted scoring by uniqueness scores. Matching authoritative engineering information is determined for the maintenance event information based on the weighted scoring, and the maintenance record is labeled with the class to which the matching authoritative engineering information is indexed.

Abstract: A method, computing system and computer program product provide additional information relating to maintenance actions to address an issue with a structure. For each maintenance action that has corrected an issue, a first group of structures in which the issue has reoccurred and a second group of structures in which the issue has not reoccurred are identified. The method then determines an actual correction duration value for each of the structures in the first and second groups, generates a correction duration estimate for the structures in the first group using the actual correction duration values and uses the correction duration estimate to identify a portion of the structures in the second group. The method also uses the actual correction duration values calculated for the first group and the identified portion of the second group to generate a fix duration estimate representing an overall time estimation for issue reoccurrence.

Abstract: A turbine blade assembly, in particular for a gas turbine, is provided. The turbine blade assembly includes a disc with a rotation axis, turbine blades, each turbine blade including an airfoil, a blade root and a platform between the airfoil and the blade root by which it may be fixed to the disc, locking plates and bent seal strips. The turbine blades are arranged adjacent to each other on the disc, such that gaps are present between the platforms of adjacent turbine blades and root cavities are present between the portions of the roots of adjacent turbine blades. The turbine blades are secured axially to the disc by the locking plates. The seal strips are arranged in the gaps between the platforms of neighboring turbine blades to seal the gap and protrude axially over the blade root and over the locking plate.

Abstract: An agreement is created between a first entity and a second entity under which the second entity agrees to provide data protection services for use by a third entity. A backup copy of the third entity's data is created and maintained at a location controlled by the second entity. If the third entity suffers a data loss, a replacement copy of the data is generated from the backup copy. The first entity provides compensation for the second entity's efforts to restore the third entity's lost data. If the second entity is unable to restore the data, the third entity is compensated for its data loss.
