Unidirectional

Unidirectional path-switched ring In unidirectional path-switched rings (UPSRs), two redundant (path-level) copies of protected traffic are sent in either direction around a ring.

The town will implement a unidirectional flushing method to be conservative, and efficient.

The new material conducts unidirectional current, or currents that only flow one way.

An MPLS connection (LSP) is unidirectional—allowing data to flow in only one direction between two endpoints.

A unidirectional distillation will rely on a pressure change in one direction, either positive or negative.

But transmission of Ca 2+ is not unidirectional; rather, it is a two-way street.

Direct current, as produced by example from a battery and required by most electronic devices, is a unidirectional flow from the positive part of a circuit to the negative.

For example, the Kam language has 9 tones: 3 more-or-less fixed tones (high, mid and low); 4 unidirectional tones (high and low rising, high and low falling); and 2 bidirectional tones (dipping and peaking).

Genes implicated in DNA repair are five times more likely to be regulated by bidirectional promoters than by unidirectional promoters.

In character encoding terms, these characters are labeled unidirectional.

In the sheltered troughs between highly developed seif dunes barchans may be formed because the wind is unidirectional.

It also describes simple links, which are unidirectional and therefore offer no more functionality than hyperlinks in HTML.

It is important to note that processes are not unidirectional: differentiated cells may regain attributes of progenitor cells.

Note that LSPs are unidirectional; they enable a packet to be label switched through the MPLS network from one endpoint to another.

One problem with some cable systems is the older amplifiers placed along the cable routes are unidirectional thus in order to allow for uploading of data the customer would need to use an analog telephone modem to provide for the upstream connection.

On inhalation and exhalation air moves through the airways in the same direction, thus creating a unidirectional airflow through the lungs.

Pet doors may be unidirectional, only allowing pets to exit.

Predetermined epigenesis is a unidirectional movement from structural development in DNA to the functional maturation of the protein.

Printing was unidirectional; if the user wanted to delete what had been typed, further characters were printed to indicate that previous text had been cancelled.

Such channel is often bidirectional, but sometimes unidirectional.
