Abstract: Disclosed herein is a method and system for generating synthetic non-destructive testing dataset. The system receives non-destructive testing datasets related to real-time experimentation of non-destructive testing as input. The testing datasets include dimensions of defective samples, expected defect morphologies, defect probabilities, the sensitivity of instruments, observation from experimental datasets, noise from instrumentation. The system performs numerical analysis on the received one or more non-destructive testing datasets containing one or more flawed geometrical features for generating one or more non-destructive training datasets by using a numerical simulation model. The system further trains a Deep Convolutional Generative Adversarial Network (DCGAN) by using the generated one or more non-destructive training datasets with flaw geometrical features.

Abstract: A method is designed and implemented to identify and quantify the different losses that are possible in a solar power plant. Data is acquired through RETINA's remote nodes from the SCADA systems which are connected to the electrical meters and sensors attached to inverters and combiner boxes in a solar power plant. The resulting data is cleansed, filtered, and archived into a data-warehouse to estimate the solar losses by devising and estimating against an “ideal” combiner box current trend. The quantified losses further form the input to a system which identifies an optimal cleaning schedule of the power plant with specifications about the labor and resources that are used.

Abstract: This invention provides a method for finding the remnant thickness of a structure. A feature of guided waves known as the cut-off property is used to determine the remnant thickness of structures. Fundamental guided wave modes do not possess cut-off property, but higher order modes do. The cut-off thickness of a particular mode is the minimum thickness required for that mode to travel through the guided medium. The invention uses a wide-bands of frequency and wavelength to generate the modes using appropriate magnets and excitation signal shape to provide a low cost and rapid evaluation of remnant thickness of structure.

The time of flight and the amplitude of the received wave modes are determined. Further, one or more properties of the fluid are measured using determined time of flight and amplitude of the received wave modes. The disclosed method is used to accurately measure the properties of fluid such as level, density, viscosity or flow rate in a short period of time.

The data is fed into one or more RETINA remote nodes and is filtering and aggregating into time intervals. The data is archived in a centralized data-warehouse and is used to build a machine learning model configured to determine ideal temperatures of components in the drive train assembly. The ideal temperatures are compared to actual measured temperatures in order to determine one or more temperature deviations. The one or more temperature deviations are used to determine a severity index score. An alert is generated corresponding to a high severity index score, wherein the alert informs of a likely imminent component failure.
