When tracks need to cross one another, they drop down or rise up to another wiring layer like an office worker going upstairs, across the building and back down again, to get around a blocked corridor.All the tracks on the first layer run in one back-and-forth direction.
Such a mechanism can be applied in nonvolatile memory devices with two logical levels "1" and "0" assigned to the two stable states which are separated by nearly equal switching forces in back and forth directions.
The Labview program also controlled merging of droplet pairs and the back-and-forth flow direction changes for the detection of absorbance over time.
A clear anticlockwise rotation is seen in a plane nearly perpendicular to the YZ plane as a whole, with occasional back-and-forth changes in direction.
P waves, also called compressional or longitudinal waves, give the transmitting medium whether liquid, solid, or gas a back-and-forth motion in the direction of the path of propagation, thus stretching or compressing the medium as the wave passes any one point in a manner similar to that of sound waves in air.
The annual parallax is the tiny back-and-forth shift in the direction of a relatively nearby star, with respect to more-distant background stars, caused by the fact that Earth changes its vantage point over the course of a year.
In this back-and-forth motion, the current flows in one direction and then in another.
After 2 passes go back and forth in any direction, it is important to alternate the mowing direction each time the lawn gets mown.
It swings back and forth in our direction, combing the breeze for our scent like some animated Hoover nozzle.
Furthermore, during CO oxidation, these reaction rate non-uniformities were found to propagate back and forth in the direction of the gas flow.
