摘要： A testing model learning apparatus 1 that can test a fracture state of a produced material with a high accuracy includes a known material data input unit 11 that receives an input of known material data indicating a distribution of hammering sound data including a plurality of characteristic values related to a hammering sound generated when a known material of which fracture state is known is struck and the fracture state of the known material, a proportion for learning calculation unit 13 that determines, based on the known material data, classes for dividing the distribution, and calculates proportions for learning that are proportions that the hammering sound data corresponding to the fracture state is included in the respective classes, and a model learning unit 14 that learns a model that outputs a fracture state of an unknown material of which fracture state is unknown, based on the proportions for learning.

摘要： A system and method (300) for calibrating an acoustic monitoring system (200) of an additive manufacturing machine (100) includes installing a calibration system (230) on the machine and performing a calibration process. Specifically, the calibration system (230) includes a calibration platform (232) removably mountable to a build platform (118) of the additive manufacturing machine (100) and having calibrated acoustic source (240) mounted thereon for defining a measurement standard. The acoustic waves generated by the calibrated acoustic source (240) are measured by the acoustic monitoring system (200) and compared to the known measurement standard to determine whether system adjustments would improve process tolerances or uniformity.

摘要： Systems, computer-implemented methods, and non-transitory computer-readable medium having a stored computer program provide characterization of multiphase fluid flow (MPF) using approximate entropy calculation techniques to enhance measuring and monitoring of a flow regime in a segment of pipe for hydrocarbon-production operations. The systems and methods can be optimized using principal component analysis.

摘要： The invention relates to a device which detects and locates an impact (17) on a structure (11). The device comprises at least three acoustic sensors (13) so that an acoustic wave (18) emitted at any point of a measurement space (12a) can be received through direct propagation by each of the sensors (13), and comprises command and control means (15) configured to process the signals corresponding to the acoustic waves received by the acoustic sensors (13), to detect the occurrence of an impact (17), and to locate a point of the structure that is the source of an acoustic wave (18). At least one optical pointer (14) is actuated by the command and control means (15) so as to designate an impact point (17) located on the structure by illuminating (22) a corresponding site of said structure.
