A computational algorithm that processes measurements to deduce an optimum estimate of the past, present, or future state of a linear system by using a time sequence of measurements of the system behavior, plus a statistical model that characterizes the system and measurement errors, plus initial condition information.

Abbreviation for key distribution center.

A unit of thermodynamic temperature, taken as one of the base units of the International System of Units (SI). The kelvin is defined by setting the thermodynamic temperature of the triple point of water at 273.16 K.
Note 1: The kelvin was formerly called "degree Kelvin. " The term "degree Kelvin" is now obsolete. No degree symbol is written with… (Read More →)

See thermodynamic temperature.

A spurious pattern or other distortion in a facsimile record copy caused by unwanted modulation products arising from the transmission of a carrier signal, and appearing in the form of a rectified baseband that interferes with the lower sideband of the carrier.
Note: The Kendall effect occurs principally when the single-sideband width is greater than half of the facsimile carrier… (Read More →)

Synonym E region.

An early generation protocol [a file-transfer and terminal-emulation program] developed for transfer of asynchronous data files, designed to help minimize the effects of interference and noise on analog telephone circuits.

A module of a program that forms a logical entity or performs a unit function.
Note: The most vulnerable portion of code in a secure operating system is a special case of a kernel.
