A back-to-back connection for electric power transmission is a high-voltage direct-current (HVDC) system with both ends in the same switchyard. This is used to couple asynchronously operated power grids or for connecting power grids of different frequencies where no DC transmission line is necessary.
This means that communication is not just the exchange of pre-established bundles of information but a creative process, unlike the outlook found in many transmission models. [ 36 ] [ 23 ] According to Robert Craig, this implies that communication is a basic social phenomenon that cannot be explained through psychological, cultural, economic ...
In this way, it differs from direct exchange, in which there is direct overlap of electron wave function from nearest neighboring cations not involving an intermediary anion or exchange center. While direct exchange can be either ferromagnetic or antiferromagnetic, the superexchange interaction is usually antiferromagnetic, preferring opposite ...
A pulse on one signal indicates when another bit of information is ready on the other signal. The asynchronous signalling methods use only one signal. The receiver uses transitions on that signal to figure out the transmitter bit rate (" autobaud ") and timing, and set a local clock to the proper timing, typically using a phase-locked loop (PLL ...
(3), is the two-site two-electron Coulomb integral (It may be interpreted as the repulsive potential for electron-one at a particular point () in an electric field created by electron-two distributed over the space with the probability density ()), [a] is the overlap integral, and is the exchange integral, which is similar to the two-site ...
One influential way to classify communication is to distinguish between linear transmission, interaction, and transaction models. [24] Linear transmission models focus on how a sender transmits information to a receiver. They are linear because this flow of information only goes in a single direction. [25]
In forms of exchange with direct reciprocity, two actors exchange resources with one another. This means, A provides value to B, and B to A. B's reciprocation of A's giving is direct [5] and each actor's outcomes depend solely on the behavior of another actor or actors.
In telecommunications, a transmission system is a system that transmits a signal from one place to another. The signal can be an electrical, optical or radio signal.The goal of a transmission system is to transmit data accurately and efficiently from point A to point B over a distance, using a variety of technologies such as copper cable and fiber-optic cables, satellite links, and wireless ...
