Abstract: A measurement device includes an electric field generator, an electric field detector, a thickness gauge, and a processor. The electric field generator generates an alternating current electric field. The electric field detector detects the alternating current electric field generated by the electric field generator. The thickness gauge measures a thickness of a measurement target in a non-contact manner. The processor derives a calibration curve representing a relationship between a specific dielectric constant and an intensity of an alternating current electric field. The measurement target is insertable between the electric field generator and the electric field detector. The electric field detector detects an intensity of the alternating current electric field attenuated by the measurement target. The processor calculates a specific dielectric constant of the measurement target based on the detected intensity of the alternating current electric field, the measured thickness, and the derived calibration curve.

Abstract: A measurement apparatus 1 according to this disclosure includes a controller 80 and a spectroscope 10 having an optical element in which an aperture 132a to pass light L1 to be measured is formed. The controller 80 executes a first process to generate a synthetic spectrum Sr(i) of the narrowed light L1 by synthesizing at least a first spectrum S1(i) when a beam spot P of the light L1 is at a first position x1 within the aperture 132a and a second spectrum S2(i) when the beam spot P of the light L1 is at a second position x2 within the aperture 132a. The first position x1 includes a position shifted to one side in a predetermined direction D from a reference position x0 of the beam spot P within the aperture 132a. The second position x2 includes a position shifted to the other side from the reference position x0.

Abstract: A system identifies a target value of one or more first operational parameters associated with an asset. The system provides the target value of the one or more first operational parameters to a machine learning model. The system receives a second target value of one or more second operational parameters associated with the asset. The system simulates one or more operations of the asset using the second target value of the one or more second operational parameters. The system provides, via a user interface, one or more recommended actions in response to a result associated with simulating the one or more operations.
