When the module is compiled into your program, all strings ( and other objects ) will get the added functionality.

:* When one types a command to the OS-9 shell, it will look first in the current module directory for a module of the specified name and will use it ( and increase its link count ) if found, or it will look on disk for an appropriately named file if not.

* When making calls to a supplier, a software module should not violate the supplier's preconditions.

The latter example leads to a generalization of modules over rings: If C is a preadditive category, then Mod ( C ) := Add ( C, Ab ) is called the module category over C. When C is the one-object preadditive category corresponding to the ring R, this reduces to the ordinary category of ( left ) R-modules.

When M is a finitely generated projective module, the endomorphism ring is central to Morita equivalence of module categories.

When interviewed on May 17 by the newspaper Komosmolskaya Pravda, Yuri Gagarin alluded to the failure of the administration to listen to the concerns about the Soyuz module that were identified by the cosmonaut corps and that Komarov's death should teach the establishment to be more rigorous in its testing and evaluation of " all the mechanisms of the spaceship, even more attentive to all stages of checking and testing, even more vigilant in our encounter with the unknown.

When the module is based upon inch measurements, it is known as the English module to avoid confusion with the metric module.

When developing software for a simulator, which can range from embedded avionics devices to 3D terrain databases by way of full motion control systems, the engineer keeps a notebook detailing the development " the build " of the project or module.

When the traction control computer ( often incorporated into another control unit, like the anti-lock braking system module ) detects one or more driven wheels spinning significantly faster than another, it invokes the ABS electronic control unit to apply brake friction to wheels spinning with lessened traction.

When R is Noetherian and M is a finitely-generated R-module, being flat is the same as being locally free in the following sense: M is a flat R-module if and only if for every prime ideal ( or even just for every maximal ideal ) P of R, the localization is free as a module over the localization.

When the field is not algebraically closed, the case where the endomorphism ring is as small as possible is of particular interest: A simple module over k-algebra is said to be absolutely simple if its endomorphism ring is isomorphic to k. This is in general stronger than being irreducible over the field k, and implies the module is irreducible even over the algebraic closure of k.
