variable FST
This group of FSTs (VAR-CC21 through
VAR-CC30) contains the logic that gives
the variables their initial configured
values.
variable index number
In the ENSTRUCT software: a unique
number that defines a variable by its type
(integer or floating-point), controller
number, LCP number, and register
number. Its format is:
TCCLLRR where
T is the type of variable
CC is the controller number
LL is the LCP number (21 through 30)
RR is the register number (01 through
16)
variables
Quantities subject to change or variability.
variables d ata
Quantitative data used for process
analysis.
variance
The square of the standard deviation.
variation
The difference among individual outputs
of a process resulting from common and
special causes.
VAX
1.A mark of Digital Equipment
Corporation for several lines of the firm’s
computers
2. Acronym: Virtual Address eXtension.
VCIA
Acronym: VME Communications
Interface Assembly
VDU
Acronym: Video Display Unit
velocity limit
A restriction on the rate of change of a
particular variable.
verify
The operation done after the training is
completed to test the neural net on data it
has not seen before. A trained neural net
might be verified many times on a
periodic basis. Certifying a neural
network prior to using it, and checking a
calibrated neural network after it is in use,
are both examples of the need to verify
neural nets.
versa module eurocard bus
(VME-bus)
A 32-bit backplane bus that has become
an industry standard. The bus uses
separate data and address lines. The
backplane uses pin and socket
connectors.
vertical scalability
The ability to run IIS on different
hardware platforms of different
computational abilities.
VGA
Acronym: Video Graphics Array
video display unit (VDU)
An electronic assembly that displays
alphanumeric data and graphic images
on a screen, for viewing by a user.
video graphics array (VGA)
A standard for video monitors and video
