A counter that is incremented by one each time an event occurs and is decremented by a fixed value periodically. [T1.218-1991]

In an optical fiber, a mode having a field that decays monotonically for a finite distance in the transverse direction but becomes oscillatory everywhere beyond that finite distance.
Note: Leaky modes correspond to leaky rays in the terminology of geometric optics. Leaky modes experience attenuation, even if the waveguide is perfect in every respect. Synonym tunneling mode.

In an optical fiber, a ray for which geometric optics would predict total internal reflection at the boundary between the core and the cladding, but which suffers loss by virtue of the curved core boundary.
Note: Leaky rays correspond to leaky (i.e., tunneling) modes in the terminology of mode descriptors. Synonym tunneling ray.

An occasional adjustment of one second, added to, or subtracted from, Coordinated Universal Time (UTC) to bring it into approximate synchronism with UT1, which is the time scale based on the rotation of the Earth.
Note 1: Adjustments, when required, are made with respect to the last second of the last minute of the day (Universal Time) on one of… (Read More →)

Dedicated common-carrier facilities and channel equipment used by a network to furnish exclusive private line service to a specific user or group of users.

1. [The] principle requiring that each subject be granted the most restrictive set of privileges needed for the performance of authorized tasks. Application of this principle limits the damage that can result from accident, error, or unauthorized use of an information system (IS). [INFOSEC-99]
2. The principle of granting only such access rights as are required for subjects to perform… (Read More →)
