Operation Stack
Operation Stack is a procedure used by Kent Police and the Port of Dover in England to park (or "stack") lorries on the M20 motorway in Kent when services across the English Channel, such as those through the Channel Tunnel or from the Port of Dover, are disrupted, for example by bad weather, industrial action, fire or derailments in the tunnel. Operation Stack is managed by Kent Police using powers under the Civil Contingencies Act 2004 and coordinated by a multi-agency group known as Operation Fennel. According to Damian Green MP, by 2007 the system had been implemented 74 times in the 20 years since it was first introduced. Causes Operation Stack is implemented whenever there is an urgent need to inhibit the flow of traffic to the Channel Tunnel and the Port of Dover, which handle 90% of freight traffic between the United Kingdom and mainland Europe. There are officially only 550 parking spaces for HGVs in Kent, so if access to cross-channel services is restricted, con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stack (abstract Data Type)
In computer science, a stack is an abstract data type that serves as a collection of elements, with two main operations: * Push, which adds an element to the collection, and * Pop, which removes the most recently added element that was not yet removed. Additionally, a peek operation can, without modifying the stack, return the value of the last element added. Calling this structure a ''stack'' is by analogy to a set of physical items stacked one atop another, such as a stack of plates. The order in which an element added to or removed from a stack is described as last in, first out, referred to by the acronym LIFO. As with a stack of physical objects, this structure makes it easy to take an item off the top of the stack, but accessing a datum deeper in the stack may require taking off multiple other items first. Considered as a linear data structure, or more abstractly a sequential collection, the push and pop operations occur only at one end of the structure, referred ...

Algebraic Stack
In mathematics, an algebraic stack is a vast generalization of algebraic spaces, or schemes, which are foundational for studying moduli theory. Many moduli spaces are constructed using techniques specific to algebraic stacks, such as Artin's representability theorem, which is used to construct the moduli space of pointed algebraic curves \mathcal_ and the moduli stack of elliptic curves. Originally, they were introduced by Grothendieck to keep track of automorphisms on moduli spaces, a technique which allows for treating these moduli spaces as if their underlying schemes or algebraic spaces are smooth. But, through many generalizations the notion of algebraic stacks was finally discovered by Michael Artin. Definition Motivation One of the motivating examples of an algebraic stack is to consider a groupoid scheme (R,U,s,t,m) over a fixed scheme S. For example, if R = \mu_n\times_S\mathbb^n_S (where \mu_n is the group scheme of roots of unity), U = \mathbb^n_S, s = \text_U ...

Stacks Blockchain
Stacks, formerly Blockstack, is an open-source platform to enable smart contracts, DeFi, NFTs, and apps for Bitcoin. Stacks blockchain is a "layer" for Bitcoin similar to the Lightning Network The Lightning Network (LN) is a "layer 2" payment protocol layered on top of Bitcoin (and other blockchains and cryptocurrencies). It is intended to enable fast transactions among participating nodes and has been proposed as a solution to the b .... In addition to smart contracts, the Stacks project provides open-source software for authentication, and data storage. Design Concerns around internet privacy, security, and data breaches brought attention to the Stacks project. Software developers have used the Stacks software to build decentralized alternatives to popular services. Stacks (STX) token is the native cryptocurrency of the Stacks blockchain, which is used as gas fee for executing smart contracts and processing transactions.

Solution Stack
In computing, a solution stack or software stack is a set of software subsystems or components needed to create a complete platform such that no additional software is needed to support applications. Applications are said to "run on" or "run on top of" the resulting platform. For example, to develop a web application, the architect defines the stack as the target operating system, web server, database, and programming language. Another version of a software stack is operating system, middleware, database, and applications. Regularly, the components of a software stack are developed by different developers independently from one another. Some components/subsystems of an overall system are chosen together often enough that the particular set is referred to by a name representing the whole, rather than by naming the parts. Typically, the name is an acronym representing the individual components. The term "solution stack" has, historically, occasionally included hardware components ...

Stack (mathematics)
In mathematics a stack or 2-sheaf is, roughly speaking, a sheaf that takes values in categories rather than sets. Stacks are used to formalise some of the main constructions of descent theory, and to construct fine moduli stacks when fine moduli spaces do not exist. Descent theory is concerned with generalisations of situations where isomorphic, compatible geometrical objects (such as vector bundles on topological spaces) can be "glued together" within a restriction of the topological basis. In a more general set-up the restrictions are replaced with pullbacks; fibred categories then make a good framework to discuss the possibility of such gluing. The intuitive meaning of a stack is that it is a fibred category such that "all possible gluings work". The specification of gluings requires a definition of coverings with regard to which the gluings can be considered. It turns out that the general language for describing these coverings is that of a Grothendieck topology. Thus a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Call Stack
In computer science, a call stack is a stack data structure that stores information about the active subroutines of a computer program. This kind of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to just "the stack". Although maintenance of the call stack is important for the proper functioning of most software, the details are normally hidden and automatic in high-level programming languages. Many computer instruction sets provide special instructions for manipulating stacks. A call stack is used for several related purposes, but the main reason for having one is to keep track of the point to which each active subroutine should return control when it finishes executing. An active subroutine is one that has been called, but is yet to complete execution, after which control should be handed back to the point of call. Such activations of subroutines may be nested to any level (recursive as a special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stacks (Mac OS)
Stacks are a feature found in Apple's macOS, starting in Mac OS X Leopard. As the name implies, they "stack" files into a small organized folder on the Dock. At the WWDC07 Keynote Presentation, Steve Jobs stated that in Leopard, the user will be given a default stack called ''Downloads'', in which all downloaded content will be placed. In the initial release of Leopard, Stacks could be shown two ways, in a "fan" or a "grid". With the release of the 10.5.2 update, a third "list" view was added. This list view allows folder icons to display their contents in pop-out side menus. Originally, if the fan view was too long to fit within the screen, it was automatically displayed as a grid. The user could also choose to have a fan stack always display as a grid, but they could not choose to make it fan out (due to the reason above). After the update, the top item in the fan would allow the user to open the folder in a Finder window. The list view also shows an Options pop-out menu wh ...
