सेमाफोरस इसके अंग्रेजी अर्थ का उदाहरण

Colour light signals replaced the semaphores.

Three semaphores are used to represent the items on the table; the agent increases the appropriate semaphore to signal that an item has been placed on the table, and smokers decrement the semaphore when removing items.

The solution is to define additional processes and semaphores that prevent deadlock, without modifying the agent.

However, David Parnas demonstrated that Patil's proof is inadequate if arrays of semaphores are used, offering a solution that uses helper processes that do arithmetic to signal the appropriate smoker to proceed.

From the 1920s onwards, upper quadrant semaphores almost totally supplanted lower quadrant signals in Great Britain, except on former GWR lines and their succession to BR(WR) and latterly Network Rail Western Zone.

The mechanical equivalents of these shunting signals are found as miniature semaphores (the arms are the same size as those of permissive signals) and disc varieties (the disc is about 12"nbsp;inches/30"nbsp;cm diameter).

The small-arm semaphores are painted in the same way as a full-size stop signal, while the discs are painted white with a red horizontal band.

There are also semaphore and disc equivalents of the yellow light shunting signals; the small-arm semaphores being painted yellow with a black stripe and the discs either black or white with a yellow stripe; by night, they show small yellow lights when "on" and small green lights when "off".

In its final years Falsgrave box controlled a mixture of colour-light and semaphore signals, including a gantry carrying 11 semaphores.

This includes support for various kinds of IO (in memory, file/disk, and so forth), thread support and various synchronization primitives like mutexes, semaphores, and conditions, Unicode string support, locale and internationalization support including localizing string resources, comprehensive resource support, and basic XML parsing.

Signalling at the station has also been modernised, with colour lights controlled from Castleton replacing the semaphores previously in use (the old signal box at Rochdale had to be demolished in 2011 as it stood in the alignment of the planned Metrolink flyover).

The hydraulic semaphores, which worked with water filled vessels and visual signals, functioned as optical telegraphs.

4th century BCE: Hydraulic semaphores.
