Abstract: Systems and methods described herein relate to indicating a repair to perform on an asset based on historic data related to a repair on the asset and/or sensor data associated with the asset. An evaluate component aggregates information related an asset such as a repair performed or data from a sensor. A repair evaluation component indicates a repair to perform on the asset based on at least one of the data from the sensor or the information related to the asset. By utilizing asset-specific information and historical data, repair schedules for assets can be more accurate and thereby reducing untimely repairs.

Abstract: An electrochemical cell structure is provided which includes an anode, a cathode spaced apart from said anode, an electrolyte in ionic communication with each of said anode and said cathode and a nonconductive frame. The nonconductive frame includes at least two components that support each of said anode, said cathode and said electrolyte and define at least one flowpath for working fluids and for products of electrochemical reaction.

Abstract: A Miller cycle combustion engine capable of operating on multiple fuel types, and a method of operating the engine, is provided. The engine includes a fuel type determiner to determine the fuel type, and a compression adjustor to adjust the compression of a first cylinder of the engine to match the requirement of the determined fuel type. The compression adjustor is a variable valve timing system that provides a maximum compression when a fuel type requiring maximum compression is determined, and that advances or retards the opening of the intake valve to provide lower compression when a fuel type requiring lower compression is determined.

Abstract: A method of quantitative non-destructive thermal inspection of an article having at least one internal cavity comprises the steps of inputting physical properties of the article, measuring thermal characteristics of the article, and calculating heat transfer coefficients of the internal cavity.

Abstract: A method for analyzing operational performance of industrial power plant machinery is disclosed. In an exemplary embodiment, the method includes receiving an input configuration for a power plant to be analyzed, and receiving inputted power plant operational information. A simulated power plant operation is then run for a specified period of time, based upon the power plant input configuration and the inputted power plant operational information. The simulated results of the simulated power plant operation are then outputted in accordance with selected economic parameters of the power plant.

Abstract: A method for low pass filtering data used in change-detect compression of data collected from a system includes buffering the data from said system. Rolling averages of the buffered data are calculated where the calculation of the rolling averages low pass filters the data. Change-detect compression is performed on the rolling averaged data, and the compressed data are archived. The archived data are transmitted to a central location and received. The received data are archived at the central location.

Abstract: Computerized method and system for identification and evaluation of a repair likely to prevent a failure of a mobile asset is provided. The method allows collecting data indicative of an incipient malfunction in the mobile asset (e.g., 1006). The method further allows collecting usage data indicative of usage of the mobile asset (e.g., 1002). The usage data is processed relative to historical data collected from a fleet of corresponding mobile assets to generate a usage profile for that asset (e.g., 1004). The data indicative of incipient malfunctions is processed to generate a prediction of a failure in the mobile asset and at least one repair likely to prevent the failure of the mobile asset (e.g., 1010). A repair weight indicative of a probability that the repair will prevent the predicted failure is determined (e.g., 466). The repair weight is adjusted based on the usage profile of the asset (e.g.

Abstract: A system has been developed for collecting and analyzing data regarding the operation of gas turbines. The system provides reports of the operational hours of a gas turbine. The reports are useful in scheduling maintenance of gas turbines. The system includes a network of sensors monitoring the gas turbine and outputting operational data to a local computer system. A remote database server periodically collects data from several on-site systems for a plurality of gas turbines, and this data is analyzed using criteria that precisely define certain gas turbine operational events in terms that can be automatically applied to operational data collected from the gas turbines.

Abstract: The fuel heat content of fuel is measured on-line while a combustion turbine system is running by measuring data from the combustion turbine system during combustion of the fuel. The measured data are corrected using a standard correction algorithm. The fuel heat content of the fuel is determined using at least a portion of the corrected data. From the measurement of the fuel heat content, any changes in the fuel heat content are determined. Also, any changes in the control and operational parameters attributable to the change in fuel heat content are determined.
