In this work, MPSO adjusts the value of inertia weight [omega],
particle velocity, and updates of particle position.
According to this law the change of the
particle velocity [v.
where U' is the
particle velocity vector relative to the gas; a is the acceleration vector of an external force field.

capable of measuring horizontal
particle velocity were placed at each fyke net.
Concluding that the human annoyance level is lower than the building damage threshold, the researchers set a ground vibration Peak
Particle Velocity (PPV) limit of lmm/s, which was not exceeded by the passing trains.
Take seismograph readings at each shot during the contract period to assure that blasting vibrations do not exceed one inch (1 ) per second
particle velocity.
Here, the velocity of centre of mass point is v and the internal
particle velocity is u.
In addition to these improvements, Type 2250 and Type 2270 portable sound level and vibration meters have been updated to measure peak
particle velocity and vibration criteria.
Figure 6 further provides a time series of local
particle velocity at the center and near the wall at two different heights.
Perfectly parallel holes permit wider shot patterns while maintaining control of fracture size, fly-rock and
particle velocity.
w] is proportional to the
particle velocity at the peak of the solitary wave (the amplitude a in Eq.
