Wave

A short-term movement that goes against the general trend. For example, if the DJIA rallies on a given trading day but overall is in the midst of a prolonged bear market, the rally is called a wave against the bearish tide.

From the numerical perspective, simulations of EMAT transduction and ultrasonic wave propagation were carried out in COMSOL Multiphysics 4.3b using the Murnaghan hyperelasticity model, harmonic generation from the fundamental longitudinal wave, while time domain signals show very small difference.
In a reference, it was assumed that the P wave or ultrasonic wave was perpendicular from the transducer's surface [25].
The feedback from the ultrasonic waves is delivered to the mathematical models so that the robotic orientation can be adjusted to maintain the normal vector of inspected surface that coincides with the beam axis of probe, if the spatial relationship between the specimen and probe is defined.
Based on the results of AE filtering experimental results, the loading process for the ultrasonic test experiments carried out in this study is as follows: (1) measure the ultrasonic wave parameters before the process of loading, (2) load up to 1.5 kN and maintain the force for 3-4 minutes; (3) load up to 4.5 kN and maintain the force for 3-4 minutes; (4) unload up to 1.5 kN and maintain the force for 3-4 minutes; (5) load up to 7.5 kN and maintain the force for 3-4 minutes; (6) unload up to 4.5 kN and maintain the force for 3-4 minutes; (7) load up to 9 kN and maintain the force for 3-4 minutes; (8) load up to the maximum stress (i.e., up to the point the coal samples produce damage) and unload completely.
After 30min of pre-treatment for the reduction of hydrocarbon contaminant with nZVI particles and ultrasonic wave, H2O2 was added at concentrations of 0, 10mM,20mM,and 30mM in solution.
The receiver detects the ultrasonic wave transmitting the specimen.
Thus straight chain homologue is functioning strongly as far as ultrasonic wave propagation is concerned.
In this respect, we may express the vector displacements of a longitudinal [u.sub.l] and of a transverse ultrasonic wave [u.sub.t] via the second quantization vector wave functions of Sound Bosons as
[5] also reported that ultrasonic waves could improve the removal of copper oxide from soil.
A schematic illustration of observations on the residual strain of the lens, which was molded with the application of 20 s of ultrasonic wave that had an off and on ratio of 0.4 s/0.4 s, is depicted in Fig.
Step 4: The ultrasonic wave form is recorded for each segment which covers the whole area of the workpiece by using ultrasonic flaw detector with constant parameters such as range, gain and velocity of the couplant.
This generates an ultrasonic wave, which can be reflected by defects, such as cracks.
