摘要： A system, a method and a computer product are disclosed. The method includes using at least one domain ontology including a plurality of domain models connected through mappings to a plurality of data sources, the data sources storing data to be accessed by the query; receiving a query by a query formulation unit; evaluating at least one of a language for defining at least one of the domain models involved in the query, a language of mappings involved in the query and a language of the query and selecting a query answering mode in accordance with results of the evaluation and retrieving an answer meeting at least one query condition from the data sources.

摘要： Methods and apparatuses for detecting corrosion in one or more blades of a gas turbine system includes a detection head having a shape that conforms to a surface geometry of a filet section of a gas turbine blade, whereby the detection head is operable to move along the axial length of the filet section for detecting corrosion pitting. At least one coil device located within the detection head induces a first magnetic field within an area of the filet in contact with the detection head. A receiver device is adapted to detect a signal corresponding to a second magnetic field received from the area of the filet exposed to the first magnetic field, where the second magnetic field is generated by induced currents in the area by the first magnetic field. A signal processing device then processes the detected signal for correlating a corresponding amplitude of the detected signal with the presence of corrosion pitting in the area such that the presence of corrosion pitting is determined without any casing disassembly of the gas turbine system.
