Operator - Wikipedia, the free encyclopedia Operators are often in practice just partial functions, a common phenomenon in the theory of differential equations since there is no guarantee that the derivative of a function exists. Operators as observables are a key part of the theory of quantum mechanics. Three main operators are key to vector calculus, the operator ∇, known as gradient, where at a certain point in a scalar field forms a vector which points in the direction of greatest change of that scalar field. en.wikipedia.org /wiki/Operator   (1531 words)

PHP: Operators - Manual (the negation operator) or ++ (the increment operator). Operators on the same line have equal precedence, in which case their associativity decides which order to evaluate them in. The table also omits the precedence (and associativity) of the "execution operator" - but since that's a sort of quoting, I don't think it meaningfully has a precedence or associativity - they explain what is to happen where there's an open-endedness in the sense of missing brackets, and the quoting is a sort of bracket. www.php.net /manual/en/language.operators.php   (1284 words)

Transfer Operator Encyclopedia Article @ Encyclopedia.LocalColorArt.com The transfer operator is sometimes called the Ruelle operator, after David Ruelle, or the Ruelle-Perron-Frobenius operator in reference to the applicability of the Frobenius-Perron theorem to the determination of the eigenvalues of the operator. Thus, transfer operators typically appear in physics problems, such as quantum chaos and statistical mechanics, where attention is focused on the time evolution of smooth functions. When the logarithm of the transfer operator corresponds to a quantum Hamiltonian, the eigenvalues will typically be very closely spaced, and thus even a very narrow and carefully selected ensemble of quantum states will encompass a large number of very different fractal eigenstates with non-zero support over the entire volume. encyclopedia.localcolorart.com /encyclopedia/Transfer_operator   (531 words)

How to Comply With Operators who follow one of these procedures acting in good faith to a request for parental access are protected from liability under federal and state law for inadvertent disclosures of a child's information to someone who purports to be a parent. Operators may use email to get parental consent for all internal uses of personal information, such as marketing back to a child based on his or her preferences or communicating promotional updates about site content, as long as they take additional steps to increase the likelihood that the parent has, in fact, provided the consent. If so, the operator also must disclose the kinds of businesses in which the third parties are engaged; the general purposes for which the information is used; and whether the third parties have agreed to maintain the confidentiality and security of the information. www.ftc.gov /bcp/conline/pubs/buspubs/coppa.htm   (2237 words)

ECMAScript 4 Operators Rationale Operator overriding is useful, for example, to implement units without having to add units to the core of the ECMAScript 4 language. The operator invocations use pseudo-syntax to denote which operator is called; only the expression syntax on the left side of the table can be used to invoke operators. User-overridable operators had originally been part of the ECMAScript 4 proposal but were deferred to a future version of the language in order to keep ECMAScript 4 small. www.mozilla.org /js/language/es4/rationale/operators.html   (1167 words)

Operator Certification FAQ Operators who possess a valid CA/NV AWWA distribution operator certificate at the time the regulation becomes effective are deemed by the regulations to have a valid DHS certificate one grade higher than the AWWA certificate they hold. Yes, if a volunteer operates a distribution system for an agency or organization (homeowner’s association, mutual water company, etc.), and the operator is a member of that agency or organization, and the operator is a customer of the system, then that operator is eligible for interim certification. Interim distribution operator certification is a tool to help operators and suppliers comply with the new distribution operator certification requirements during the first 3 to 6 years that the regulation is effective. www.dhs.ca.gov /ps/ddwem/publications/opcert/FAQ.htm   (3363 words)

Image Arithmetic - Exponential/Raise to Power Operator The exponential operator is the dual of the logarithmic transform. In the case of the `raise to the power' operator, the pixel intensity values in the input image act as the basis which is raised to a (fixed) power. Like the logarithmic operator, the exponential and `raise to power' operators might be used to compress the dynamic range or generally enhance the visibility of an image. homepages.inf.ed.ac.uk /rbf/HIPR2/pixexp.htm   (1184 words)

Operator Overloading Since the overloaded subscript operator returns a reference (specifically an "int&"), it is legitimate to have the subscript operator appear in an expression on the left-hand side of the assignment operator. While all of these operator have a predefined and unchangeable meaning for the built-in types, all of these operators can be given a specific interpretation for different classes or combination of classes. Again notice that there is nothing "special" about the operator[] method, except that its name must be exactly as written in order to communicate to the compiler that this method is, in fact, to be treated as an overloading of the built-in "[]" operator for objects of the Array class. people.cs.vt.edu /~kafura/cs2704/op.overloading.html   (1231 words)

Oliver Sturm’s weblog - The ?? operator (C# 2.0) operator: It’s an extension in C# 2.0 (find the specs here, this operator is explained on page 14, then end of chapter 19.5) and they call it a null coalescing operator. operator are nullable types, the return type will be the same nullable type. So this should really make the purpose of the operator quite clear: check something for null, return the same something if it’s not null, the given alternative value otherwise. www.sturmnet.org /blog/archives/2005/06/15/doublequestionmark   (391 words)

Operator The basic operators available in all programming languages are plus (+), minus (-), divide (/), times (*), greater than (>), less than (<), greater than or equal to (>=), and less than or equal to (<=). For example, in "1 + 2", the "1" and "2" are the operands and the plus symbol is the operator. In computer programming, an operator is an object that is capable of manipulating a value or operator. www.computerhope.com /jargon/o/operator.htm   (118 words)

Secret Service Operator #5 -- America's Undercover Ace! Many of the Operator 5 cover paintings bear likenesses of Diane: strapped to the muzzle of a cannon; about to be hurled from a giant catapult; facing firing squads; tied to dynamite kegs, and once- - shades of Pearl White-bound to railroad tracks, the thundering locomotive mere yards away. There is a bond of affection between Z-7 and Operator 5, a bond which is sorely tested in the course of the novels. They had met one drenching night on the lower East Side, when Tim, a bootblack huddling in a dark doorway, had saved Operator 5 from death by a bullet from a criminal's gun. members.aol.com /opnumber5   (887 words)

CREATE OPERATOR A commutator is another existing operator which executes the commutation (order reversal) of the procedure defined for the new operator, e.g., with the left argument treated as the right argument, and the right argument treated as the left argument. These sorting operators should only be given for an equality operator, and when they are given they should be represented by less-than and greater-than symbols for the left- and right-hand data types, respectively. A negator is another existing operator which executes the literal inversion of the procedure define for the new operator. www.faqs.org /docs/ppbook/r24536.htm   (983 words)
