Euclidean Vector
In mathematics, physics, and engineering, a Euclidean vector or simply a vector (sometimes called a geometric vector or spatial vector) is a geometric object that has magnitude (or length) and direction. Euclidean vectors can be added and scaled to form a vector space. A '' vector quantity'' is a vector-valued physical quantity, including units of measurement and possibly a support, formulated as a '' directed line segment''. A vector is frequently depicted graphically as an arrow connecting an ''initial point'' ''A'' with a ''terminal point'' ''B'', and denoted by \stackrel \longrightarrow. A vector is what is needed to "carry" the point ''A'' to the point ''B''; the Latin word means 'carrier'. It was first used by 18th century astronomers investigating planetary revolution around the Sun. The magnitude of the vector is the distance between the two points, and the direction refers to the direction of displacement from ''A'' to ''B''. Many algebraic operations on real numbe ...

Vector Clock
A vector clock is a data structure used for determining the partial ordering of events in a distributed system and detecting causality violations. Just as in Lamport timestamps, inter-process messages contain the state of the sending process's logical clock. A vector clock of a system of ''N'' processes is an array/vector of ''N'' logical clocks, one clock per process; a local "largest possible values" copy of the global clock-array is kept in each process. Denote VC_i as the vector clock maintained by process i, the clock updates proceed as follows: * Initially all clocks are zero. * Each time a process experiences an internal event, it increments its own logical clock in the vector by one. For instance, upon an event at process i, it updates VC_ \leftarrow VC_ + 1. * Each time a process sends a message, it increments its own logical clock in the vector by one (as in the bullet above, but not twice for the same event) then it pairs the message with a copy of its own vector ...

Pinzgauer High-Mobility All-Terrain Vehicle
The Pinzgauer is a family of high-mobility off-road vehicle, all-terrain four-wheel drive, 4WD (4×4) and six-wheel drive, 6WD (6×6) military utility vehicles. The vehicle was originally developed in the late 1960s and manufactured by Steyr-Daimler-Puch of Graz, Austria, and was named after the Pinzgauer cattle, Pinzgauer, an Austrian breed of cattle. They were most recently manufactured at Guildford, Surrey, England, by BAE Systems Land & Armaments. It was popular amongst military buyers, and continued in production there throughout the rest of the century. In 2000 the rights were sold to Automotive Technik, Automotive Technik Ltd (ATL) in the UK. ATL was acquired by Stewart & Stevenson, Stewart & Stevenson Services, Inc. in 2005. In May 2006, Stewart & Stevenson became a subsidiary of the aerospace and defence group Armor Holdings, Inc.

Radar Vector
In aviation, instrument flight rules (IFR) is one of two sets of regulations governing all aspects of civil aviation aircraft operations; the other is visual flight rules (VFR). The U.S. Federal Aviation Administration's (FAA) ''Instrument Flying Handbook'' defines IFR as: "Rules and regulations established by the FAA to govern flight under conditions in which flight by outside visual reference is not safe. IFR flight depends upon flying by reference to instruments in the flight deck, and navigation is accomplished by reference to electronic signals." It is also a term used by pilots and controllers to indicate the type of flight plan an aircraft is flying, such as an IFR or VFR flight plan. Basic information Comparison to visual flight rules It is possible and fairly straightforward, in relatively clear weather conditions, to fly an aircraft solely by reference to outside visual cues, such as the horizon to maintain orientation, nearby buildings and terrain features for ...

Hall Vector 1
The Hall Vector 1 is an American high-wing, ultralight glider that was designed by Stan Hall for serious cross-country flights.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 44. Soaring Society of America, November 1983. USPS 499-920 Design and development The Vector 1 was intended to take advantage of the US informal rules for hang gliders at the time of its development that in 1982 became the FAR 103 Ultralight Vehicles regulations. These define a hang glider as any unpowered glider with an empty weight of or less. The Vector 1 was designed with the goal of building a foot-launchable glider with cross country performance. With an empty weight of , the design qualifies as a hang glider and thus does not need to be registered or have a Certificate of Airworthiness. The aircraft resembles a small sailplane and not a traditional hang glider. The aircraft achieves its light weight through small dimensions, with a wingspan of only . The Vector 1 was design ...

Vector (robot)
Cozmo is a miniature robot created by the defunct company Anki (American company), Anki. Cozmo's base model, is a small, white and gray robot with red highlights. It makes use of distinct expressions, dubbed the "emotion engine", in order to mimic human emotion. Later editions came in red and white, gray and black and another in blue. Functions Cozmo has a companion Mobile app, app for smartphones that connects via Wi-Fi, used to both allow better interaction between Cozmo and the user, as well as offloading heavier processing requirements to the smartphone. Cozmo sees its environment with a camera capable of detecting faces. In November 2016, its camera was updated to include "night vision". Cozmo has an "explorer mode", in which the user can manage Cozmo while it moves around its environment. Included with Cozmo are proprietary blocks that contain sensors, used both to play games and allow Cozmo to maintain a better sense of its environment. Use of these blocks allows for ...

Vector (malware)
In computer security Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and computer network, n ..., an attack vector is a specific path, method, or scenario that can be exploited to break into an IT system, thus compromising its security. The term was derived from the corresponding notion of vector in biology. An attack vector may be exploited manually, automatically, or through a combination of manual and automatic activity. Often, this is a multi-step process. For instance, malicious code (code that the user did not consent to being run and that performs actions the user would not consent to) often operates by being added to a harmless seeming document made available to an end user. When the unsuspecting end user opens the document, the malicious code in question (known as the payload) is executed and pe ...

Vector Game
A variety of computer graphic techniques have been used to display video game content throughout the history of video games. The predominance of individual techniques have evolved over time, primarily due to hardware advances and restrictions such as the processing power of central or graphics processing units. Text-based Some of the earliest video games were text games or text-based games that used text characters instead of bitmapped or vector graphics. Examples include MUDs (''multi-user dungeons''), where players could read or view depictions of rooms, objects, other players, and actions performed in the virtual world; and roguelikes, a subgenre of role-playing video games featuring many monsters, items, and environmental effects, as well as an emphasis on randomization, replayability and permanent death. Some of the earliest text games were developed for computer systems which had no video display at all. Text games are typically easier to write and require less pro ...
