First, based on the broadband that is typical of blast waves, the peak frequency of the P-wave was obtained in the time–frequency domain, taking advantage of the difference in the propagation speed of the P-wave, S-wave, and the surface wave. Second, the phase difference between two ...
(H2): Innovative environment has a positive effect on technology innovation, while regional differences and temporal variations of effect size exist. There are many arguments about the relationship between enterprise scale and innovation efficiency [35,36]. For instance, Pavitt, Robson and Townsend (...
The instantaneous opening speed of the relief valve spool reaches 15.7 m/s, and the hinge point between the top beam and the column is most sensitive to the hysteresis effect (impact coefficient increases by 0.63). Keywords: hydraulic support; rotary impact; dynamic response; mechanical-hydraulic...
The examples of measured DC transfer characteristics between input voltage (VY) and output current (IZ), are shown in Figure 3a; VX serves as the DC constant, driving overall transconductance (in accordance to gm ≅ 1.3 × 10−3 VX). The gain bandwidth (GBW) of the real prototype ...
The function relation has been detected between MC value for a mapped eigenvector and its corresponding eigenvalue as follows: MCj = n 1TC1 λj (3) Based upon these properties, the eigenvectors can be interpreted as follows: The first eigenvector E1 is the set of real numbers that has ...
