9. an expansion joint. See below. [Colloq. or jargon]
[PJC]
Expansion curve, a curve the co["o]rdinates of which show
the relation between the pressure and volume of expanding
gas or vapor; esp. (Steam engine), that part of an
indicator diagram which shows the declining pressure of
the steam as it expands in the cylinder.
Expansion gear (Steam Engine). a cut-off gear. See Illust.
of Link motion.
Automatic expansion gear or Automatic cut-off, one that
is regulated by the governor, and varies the supply of
steam to the engine with the demand for power.
Fixed expansion gear, or Fixed cut-off, one that always
operates at the same fixed point of the stroke.
Expansion joint, or Expansion coupling (Mech. & Engin.),
a yielding joint or coupling for so uniting parts of a
machine or structure that expansion, as by heat, is
prevented from causing injurious strains; as:
(a) A slide or set of rollers, at the end of bridge truss,
to support it but allow end play.
(b) A telescopic joint in a steam pipe, to permit one part
of the pipe to slide within the other.
(c) A clamp for holding a locomotive frame to the boiler
while allowing lengthwise motion.
(d) a strip of compressible material placed at intervals
between blocks of poured concrete, as in roads or
sidewalks.
Expansion valve (Steam Engine), a cut-off valve, to shut
off steam from the cylinder before the end of each stroke.

Triple-expansion steam engine
(gcide) | Triple \Tri"ple\, a. [L. triplus; tri- (see Tri-) + -plus, as
in duplus double: cf. F. triple. See Double, and cf.
Treble.]
1. Consisting of three united; multiplied by three;
threefold; as, a triple knot; a triple tie.
[1913 Webster]
By thy triple shape as thou art seen. --Dryden.
[1913 Webster]
2. Three times repeated; treble. See Treble.
[1913 Webster]
3. One of three; third. [Obs.] --Shak.
[1913 Webster]
Triple crown, the crown, or tiara, of the pope. See
Tiara, 2.
Triple-expansion steam engine, a compound steam engine in
which the same steam performs work in three cylinders
successively.
Triple measure (Mus.), a measure of tree beats of which
first only is accented.
Triple ratio (Math.), a ratio which is equal to 3.
Triple salt (Chem.), a salt containing three distinct basic
atoms as radicals; thus, microcosmic salt is a triple
salt.
Triple star (Astron.), a system of three stars in close
proximity.
Triple time (Mus.), that time in which each measure is
divided into three equal parts.
Triple valve, in an automatic air brake for railroad cars,
the valve under each car, by means of which the brake is
controlled by a change of pressure in the air pipe leading
from the locomotive.
[1913 Webster] |
coefficient of expansion
(wn) | coefficient of expansion
n 1: the fractional change in length or area or volume per unit
change in temperature at a given constant pressure [syn:
coefficient of expansion, expansivity] |
expansion
(wn) | expansion
n 1: the act of increasing (something) in size or volume or
quantity or scope [syn: expansion, enlargement] [ant:
contraction]
2: a function expressed as a sum or product of terms; "the
expansion of (a+b)^2 is a^2 + 2ab + b^2"
3: a discussion that provides additional information [syn:
expansion, enlargement, elaboration]
4: adding information or detail [syn: expansion, {expanding
upon}] |
expansion bit
(wn) | expansion bit
n 1: a bit with a cutting blade that can be adjusted to
different sizes [syn: expansion bit, expansive bit] |
expansion bolt
(wn) | expansion bolt
n 1: a bolt that has an attachment that expands as the bolt is
driven into a surface |
expansion slot
(wn) | expansion slot
n 1: (computer) a socket in a microcomputer that will accept a
plug-in circuit board; "the PC had three slots for
additional memory" [syn: slot, expansion slot] |
expansionism
(wn) | expansionism
n 1: the doctrine of expanding the territory or the economic
influence of a country |
expansionist
(wn) | expansionist
adj 1: of or involving or guided by expansionism |
eta expansion
(foldoc) | eta conversion
eta abstraction
eta expansion
eta reduction
In lambda-calculus, the eta conversion rule states
\ x . f x f
provided x does not occur as a free variable in f and f is a
function. Left to right is eta reduction, right to left is
eta abstraction (or eta expansion).
This conversion is only valid if bottom and \ x . bottom are
equivalent in all contexts. They are certainly equivalent
when applied to some argument - they both fail to terminate.
If we are allowed to force the evaluation of an expression in
any other way, e.g. using seq in Miranda or returning a
function as the overall result of a program, then bottom and
\ x . bottom will not be equivalent.
See also observational equivalence, reduction.

expansion card
(foldoc) | expansion card
A circuit board which can be plugged into one of a
computer's expansion slots to provide some optional extra
facility such as additional RAM, disk controller,
coprocessor, graphics accelerator, communication device or
some special-purpose interface.
Different computers have different standards for the cards
they accept, e.g. PCI.

expansion slot
(foldoc) | expansion slot
A connector in a computer into which an {expansion
card} can be plugged. The connector supplies power to the
card and connects it to the data bus, address bus and
control signals of the motherboard.

query expansion
(foldoc) | query expansion
Adding search terms to a user's
search. Query expansion is the process of a search engine
adding search terms to a user's weighted search. The
intent is to improve precision and/or recall. The
additional terms may be taken from a thesaurus. For example
a search for "car" may be expanded to: car cars auto autos
automobile automobiles.
The additional terms may also be taken from documents
that the user has specified as being relevant; this is the
basis for the "more like this" feature of some search engines.
The extra terms can have positive or negative weights.
