an function object that references a specific inner scope

a pair consisting of a code pointer with its bound variables, and is invoked by jumping to its left member and passing itself as the first argument

a record that contains references to all variables that are in scope for a certain part of the compiled scope

a representation of a function that contains (i) the function's definition, including both the formal parameter(s) and the function's body, and (ii) a copy/snapshot of the enviroment in which the function was declared/created

A function which references local variables created by a local declaration surrounding the function definition.

In computer science, a closure is a semantic concept referring to a function paired with an environment. When called, the function can reference elements of the environment required for the function’s evaluation. Typically, a closure occurs when one function appears entirely within the body of another, and the inner function refers to local variables of the outer function.

approaching a particular destination; a coming closer; a narrowing of a gap; "the ship's rapid rate of closing gave them little time to avoid a collision"

a Gestalt principle of organization holding that there is an innate tendency to perceive incomplete objects as complete and to close or fill gaps and to perceive asymmetric stimuli as symmetric

Marshall McLuhan's term for the act of filling in gaps and details in an iconic or abstracted representation of something. When we see two dots and a curved line as a face, we are committing an act of closure. See also Cool media

A factor in visual grouping. The perceptual tendency to fill in gaps in a figure so that it looks complete.

Mental process whereby one perceives an incomplete from as though it were complete.

1) The human tendency to perceive a "whole" from incomplete parts. 2) The human tendency to unconsciously fill in gaps in sequences and patterns. In comics, closure is often used to create the illusion of time and motion. According to McCloud, closure forms the "grammar" of comics.

Any mechanical part which seals a port or chamber.

A cap, plug or cover for a fluid passage.

Compare? The procedure an operator must go through when a landfill reaches the legal capacity for solid waste. No more waste can be accepted and a cap usually is placed over the site. The cap is then planted with grasses and other ground covers.

The joint or seal made in attaching the cover to a can; as in double seaming.

A cap enabling PET bottles to remain airtight even after being opened. Closures are generally made of polypropylene. During recycling, a soak/sink mechanism allows the polypropylene to be separated from PET.

the device used to seal a bottle, e.g., cork, cap, stopper, etc. IGCB

The procedure a landfill operator must follow when a landfill reaches its legal capacity for solid ceasing acceptance of solid waste and placing a cap on the landfill site.

A term used to describe a metal or molded cap or plug which effects a primary seal when properly applied to a container.

A sealing or covering device affixed to or on a container for the purpose of retaining the contents and preventing contamination.

A devise used to seal off the opening of the bottle to prevent the loss of its contents.

During the closure period, certain activities must be performed to comply with environmental and other regulations (e.g. capping, landscaping, etc.).

The means by which a container is sealed and its contents retained.

Four-way (all round) closure or seal is necessary, over the top and down the gradients on the sides of a potential reservoir, before it can trap or retain hydrocarbons. Closure may be structural as in an anticline, or may be partly due to an impermeable fault, or stratigraphic trapping.

means used to close a package where no seal is formed EXAMPLE: Repeated folding to construct a tortuous path (ref. ISO 11607:2003(E)).

The way in which an envelope is sealed at the opening.

the question "that the question be now put", i.e. that, although there are still members speaking or wishing to speak, the debate should be ended and the House proceed immediately to a decision. The Speaker has discretion as to whether to accept the closure and, if opposed, it requires not just a majority but also at least 100 members voting in favour; otherwise, the original debate is resumed. If the closure is agreed to, the question is then put immediately on the matter previously under debate.

A procedure forbidding further adjournment of debate on any motion or on any stage of a bill and requiring that the motion come to a vote at the end of the sitting in which it is invoked.

The procedure by which a debate may be terminated by a majority decision of the house, even though all members wishing to speak may not have had the opportunity to do so.

the property of being mathematically closed under some operation; -- said of sets.

the intersection of all closed sets containing the given set.

A packaging component used to close a container or package.

A device such as a latch or snap, or method such as a draw string used to keep a compartment or pocket of a handbag closed.

The closure of a set is the smallest closed set containing the original set. It is equal to the intersection of all closed sets which contain it. An element of the closure of a set ''S'' is a point of closure of ''S''.

All missions of the installation have ceased or have been relocated. All personnel positions (military, civilian and contractor) have either been eliminated or relocated, except for personnel required for caretaking, conducting any ongoing environmental cleanup, and property disposal of the base, or personnel remaining in authorized enclaves.

The process by which a landfill stops accepting wastes and is shut down under federal or state guidelines that ensure the public and the environment is protected.

any system used for opening and closing packaging.

Actions taken at the termination of a disposal operation which are necessary to finally close the disposal facility or disposal facility parcel. SWM Rule Chapter 1200-1-7-.01(2)

The procedure to be followed and actions to be taken when a disposal site is to be closed.

A set of numbers is closed under an operation if combining any two elements in the set by that operation yields a number in the set.

The closure of a set S under some operations, is the set of everything you can get by starting with S, then repeatedly applying the operations. For instance, the closure of the set {1} under addition and subtraction is the set of integers.

Any structure or device which is designed to close off the opening of a container and prevent loss of its contents.

Refers to Israel's closing of its borders with the territories. (Many Palestinians depend for income on jobs in Israel.) Jerusalem has been under closure since 1993. Also refers to "Internal Closure" where Palestinians are not allowed to move from city to city within the territories.

Usually “closure” occurs when a consumer has been employed for 90 days, and the counselor and consumer may close the case as a success. Closure can occur for other reasons.

The closure of a set is the intersection of all closed sets which contain it. It is the smallest closed set containing the original set.

A set of things, such as numbers, is closed under an operation if the application of the operation to any members in the set always results in numbers of that set.

In mathematics, the closure of a set S consists of all points which are intuitively "close to S". A point which is in the closure of S is a point of closure of S. The notion of closure is in many ways dual to the notion of interior.

In mathematics, a set is said to be closed under some operation if the operation on members of the set produces a member of the set. For example, the real numbers are closed under subtraction, but the natural numbers are not: 3 and 7 are both natural numbers, but the result of 3 − 7 is not.

bringing a narrative to a conclusion that is satisfactory. Proper closure accounts for all the clues and mysteries, leaves no stray ends, makes themes clear, and gives readers a sense that order is again in sight.

The subjective sense of ending or completion -- as when experiencing the end of a sentence. In music, ending gestures are called cadences. Narmour has defined closure as the absence of psychological expectations. See also cadence.

the sense of completion at the end of a poem

the ending of the poem.

In psychology, closure may refer to the state of experiencing an emotional conclusion to a difficult life event, such as the breakdown of a close interpersonal relationship or the death of loved one. People may behave in a certain way or perform certain rituals to help "bring closure" following such events. In many other cases, "closure" may only come about through the passage of time (as in "time heals all wounds").

a run-time data structure that represents a procedure by representing both its code and the environment in which that code was declared, or closed

a safe procedure - whichever way it is done

a user-defined procedure

Trademarked name of saphenous vein ablation done using radiofrequency energy. Closure is usually done in the office and uses local anesthesia. The Closure procedure replaces the older surgical procedures of vein stripping and high ligation of the saphenous vein.

The Closure procedure is an outpatient (day surgery) treatment performed in hospitals, surgical centers and doctor's offices. Anesthesia is typically used to numb the treatment area. The Closure Catheter is inserted into the vein through a small opening, often using only a single needle stick. The catheter delivers radiofrequency (RF) energy to the vein wall, causing it to heat, collapse and seal shut as the doctor pulls the catheter from the vein. Like other venous procedures, the Closure procedure involves risks and potential complications. Patients should consult their doctors to determine whether or not they are candidates for this procedure, and if their conditions present any special risks.

A door that allows quick and easy access to the inside of a pressure vessel, i.e., pig launcher, receiver, strainer. Pigs are inserted into and removed from a launcher/receiver through the closure door. Closures may be either threaded or clamp-ring type.
