摘要： A system for similarity analysis-based information augmentation for a target component includes an information augmentation (IA) computer device. The IA computer device identifies a target component input variable with unavailable data. The IA computer device executes a similarity analysis function, identifying at least two test components with data for the input variable exceeding a threshold. The IA computer device generates parameter distributions for test data for each test component. The IA computer device generates model coefficients using the parameter distributions, determining a proportional mix of the parameter distributions. The IA computer device authors a predictive model configured to generate at least one predicted value for the target data for the at least one input variable for the target component by including the at least one model coefficient in the predictive model. The IA computer device generates, using the predictive model, the at least one predicted value.

摘要： A fluid sensor cable assembly and method uses one or more conductive bodies extending along an elongated core body for conducting a heating current to heat the cable assembly. The one or more conductive bodies also are configured to conduct an interrogation signal and to conduct reflections of the interrogation signal. One or more optical fibers extend along the length of the core body and include temperature sensitive elements at different locations along the length of the core body. The temperature sensitive elements measure heat flux out of the cable assembly at the different locations subsequent to heating the cable assembly and communicate the heat flux to a computer acquisition system.

摘要： A sensing system that includes an optical fiber disposed helically around an outer surface of a structure along a longitudinal axis of the structure is provided. The optical fiber is disposed such that at least one complete helical turn of the optical fiber covers the length of the structure. Further, the sensing system also includes a fiber Bragg grating (FBG) set comprising a plurality of FBGs in the optical fiber. Each FBG in the set is configured to generate reflected light that is indicative of strain values at a location of each respective FBG on the optical fiber. Furthermore, the system also includes a processing system coupled to the optical fiber. The processing system is configured to determine location coordinates of each FBG and values of one or more of bending moment, tensile force, and torsional moment acting at each FBG location on the optical fiber.

摘要： A system is provided for monitoring strain in a substrate using a strain sensor element within a fiber optic sensing cable. Accurate and rapid measurement of strain of remote substrates presents major technical challenges and is the focus of much of the description presented. However, systems, methods and devices provided by the present invention are not only capable of reliably measuring strain in real time, but are also capable of measuring other characteristics of a substrate such as its temperature, pressure and its acoustic characteristics. The system is configured such that a strain sensor element within a strain sensing zone detects substantially the true strain characteristics of the substrate. And while other sensing elements within the same fiber optic sensing cable may not be configured to detect substrate strain at all, these sensing elements may reliably measure the temperature and pressure at the surface of the substrate adjacent to the strain sensing zone.
