摘要： Non-destructive inspection systems (10) and methods for inspecting structural flaws that may be in a structure (15) based on guided wave thermography. The method may include sweeping a frequency-phase space to maximize ultrasonic energy distribution across the structure while minimizing input energy, e.g., via a plurality of actuators. The system may include transducer elements (12, 14, 16, 17) configured to predominantly generate shear horizontal-type guided waves in the structure to maximize thermal response from any flaws.

摘要： The present inventors have developed systems and processes for reducing the overall carbon consumption needed for the generation of low COD treated water. In certain aspects, the systems and processes described herein include an oxidation stage (e.g., one that utilizes ozone, hydrogen peroxide, ultraviolet, or a combination thereof for oxidation) between a first activated carbon stage and a second activated carbon stage to reduce a total carbon consumption within the associated system or process.

摘要： System for hydraulic fracturing is provided. The system may involve a mobile hydraulic fracturing subsystem including a variable frequency drive (VFD) (12) electrically coupled to a generator (50). An electric motor (14) is driven by VFD (12). Harmonic mitigation circuitry (16) is configured to mitigate harmonic distortion by VFD (12). A hydraulic pump (20) is driven by motor (14) to deliver a pressurized fracturing fluid. VFD (12), harmonic mitigation circuitry (16), motor (14) and hydraulic pump (20) may be arranged on a mobile platform (24) so that a subsystem so arranged can be transportable from one physical location to another. In some disclosed embodiments, the hydraulic fracturing subsystem may be fitted on mobile platform (24) having size and weight not subject to laws or regulations requiring a permit and/or accompaniment by an escort vehicle to travel on a public highway, such as public highways in the United States and/or Canada.

摘要： A method of manufacturing a substrate (16) with a ceramic thermal barrier coating (28, 32). The interface between layers of the coating contains an engineered surface roughness (12, 24) to enhance the mechanical integrity of the bond there between. The surface roughness is formed in a surface of a mold (10,20) and is infused by a subsequently cast layer of material (16, 28). The substrate may be partially sintered (76) prior to application of the coating layer(s) and the coated substrate and coating layer(s) may be co-sintered to form a fully coherent strain-free interlayer.

摘要： Methods and systems are provided for evaluating robustness of engineering components. An example method includes receiving an engineering problem definition for a multidimensional engineering domain of an engineering component, in which the engineering problem definition includes a description of a plurality of engineering features of the engineering component. Executing an optimal stratified sampling algorithm that obtains a plurality of probabilistic samples from the multidimensional engineering domain. Selecting optimal combinations of higher fidelity models, reduced order models and response surfaces for execution of the probabilistic samples. Executing the probabilistic samples using the selected combinations to determine a respective engineering response for each engineering feature of the plurality of engineering features. Generating a robustness scorecard for the engineering component based on the determined engineering responses to quantify a robustness score for each engineering feature of the plurality of engineering features. Presenting the robustness scorecard to a user.
