Energy used in the RF welding process, typically 27 MHz, is applied to the electrodes, and the resulting alternating current induces a rapidly reversing (several million times per second) electric field around the parts. Polar molecules tend to orient in the field direction, so that the positive...

When the mass is at rest (x1=0) and it is pushed or pulled in a downward direction (dx1/dt=x2>0), the flow moves in a clockwise direction (note the direction of the slope field arrows), with x2 decreasing and x1 increasing until the trajectory is at the x1-axis. Physically, ...
and a length of vertical conductor 3 is moved around the antenna in a cylindrical path, negligible effect is produced upon the field affecting the antenna I. This is true when the conductor 3 is short with respect to the

s a signal indicative of the horizontal displacement of the laser beam receiving device of a leading element during construction work along a straight line and selects a signal indicative of the horizontal displacement of an induced magnetic field generator during construction work along a curve. ...
To measure the distribution of switching fields [7] the suspension was oriented by a dc magnetic field, and the birefringence monitored continuously. A very short current pulse through the electromagnet then caused a momentary strong magnetic field in the reverse direction. Those particles for which...
We proposed the TPIOF method to quantitatively estimate full-field blood-flow velocity. This method addresses issues commonly found in conventional optical flow methods, such as background noise and velocity underestimation, through the implementation of temporal direction filtering, and peak interpolation...
According to Faraday’s law of electromagnetic induction, when a coil cuts a magnetic field, it generates current, the size of which is related to the number of turns of the coil, the cross-sectional area of the coil, the distance between the coil and the permanent magnet, the relative sp...
