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. Vectors can be added to other vectors according to vector algebra. A Euclidean vector is frequently represented by a '' directed line segment'', or graphically as an arrow connecting an ''initial point'' ''A'' with a ''terminal point'' ''B'', and denoted by \overrightarrow . A vector is what is needed to "carry" the point ''A'' to the point ''B''; the Latin word ''vector'' 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 numbers such as addition, subtraction, multiplication, and negation have close analogues for vectors, operations whic ...

Vector Space Model
Vector space model or term vector model is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers (such as index terms). It is used in information filtering, information retrieval, indexing and relevancy rankings. Its first use was in the SMART Information Retrieval System. Definitions Documents and queries are represented as vectors. :d_j = ( w_ ,w_ , \dotsc ,w_ ) :q = ( w_ ,w_ , \dotsc ,w_ ) Each dimension corresponds to a separate term. If a term occurs in the document, its value in the vector is non-zero. Several different ways of computing these values, also known as (term) weights, have been developed. One of the best known schemes is tf-idf weighting (see the example below). The definition of ''term'' depends on the application. Typically terms are single words, keywords, or longer phrases. If words are chosen to be the terms, the dimensionality of the vector is the number of words in the vocabulary (the number of dist ...

Vector W2
The Vector W2 was a fully functional concept car intended for production constructed by Vector Motors in 1978. It had a Bosch fuel injected twin-turbocharged 350 cid (5.7 L) aluminum Chevrolet V8 engine that produced over 600 hp (450 kW) and over 600 ft·lbf (800 N·m) of torque. The top speed was a claimed 242 mph (389 km/h). The name comes from the "W" for Jerry Wiegert (designer and founder of Vector Motors) and "2" for the number of turbochargers. Over the time prior to production the car went through a number of improvements in performance, technology, updated styling exercises, as well as color changes. The car was displayed at international auto shows worldwide, and featured in many automotive publications. Between 1978 and 1987, Wiegert attempted to raise the money to start series of the car. In its lifetime, the car covered over in testing, more than any other concept car. In 1989, the final version of the W2 went into production as the Vec ...

Vector M12
The Vector M12 is a sports car manufactured by Vector Aeromotive under parent company Megatech, and was the first car produced after the hostile takeover of the company from Jerry Wiegert by the Indonesian company Megatech. The model was produced from 1995 to 1999, when production was halted due to slow sales of the car. The production totaled 17 units including the prototypes. History and specifications The car was based on the Lamborghini Diablo utilising most of its mechanical components and its V12 engine as Megatech owned Lamborghini at that time and took such steps to produce the car in higher volumes at a low cost. The engine was centrally mounted in front of the gearbox rather than behind it as in the Lamborghini. The styling was a loose copy of the AWX-3, which was a still born project due to the Megatech takeover and later infringed by former company owner Wiegert after he initiated lawsuits and patented the designs to avoid them being reused. The new owners, Megat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saab 9-3
The Saab 9-3 (pronounced ''nine-three'') is a compact executive car initially developed and manufactured by the Swedish automaker Saab. The first generation 9-3 (1998-2003) is based on the GM2900 platform, changing to the GM Epsilon platform with the introduction of the second-generation car (2003-2012). Other vehicles using this platform include the Opel Vectra, Chevrolet Malibu, and Cadillac BLS. Saab's last owners, National Electric Vehicle Sweden (NEVS), assembled the 9-3 sedan as Saab's only model. Overview The car was badged as 93 starting in the 1998 model year when Saab revised the naming strategy of their small car to match that of their larger 95. The model was marketed as 9-3, pronounced as "nine three.” The Saab 9-3 was launched in 1998 for the 1999 model year essentially as a rebadged second-generation Saab 900 (1994–1998 model) and succeeded by a redesigned 9-3 for the 2003 model year. It is not to be confused with the Saab 93 (pronounced "ninety-three"), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pinzgauer High-Mobility All-Terrain Vehicle
The Pinzgauer is a family of high-mobility all-terrain 4WD (4×4) and 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, an Austrian breed of cattle. They were most recently manufactured at Guildford in 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 Ltd (ATL) in the UK. ATL was acquired by Stewart & Stevenson Services, Inc. in 2005. In May 2006, Stewart & Stevenson became a subsidiary of the aerospace and defence group Armor Holdings, Inc. In 2007 Armor Holdings was acquired by BAE Systems plc, who discontinued UK production of the Pinzgauer, which was proving to be vulnerable to mines and improvised explosive devices in Afghanistan. Production ceased around 2009. Development wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 designed ...

Vector (malware)
In computer security, 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 performs the abusive tasks it was programmed to execute, which may include things such as spreading itself further, opening up unauthorized access to the IT system, stealing or encrypting the user's documents, etc. In order to limit the chance of discovery ...

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 process ...
