Span (unit)
A span is the distance measured by a human hand, from the tip of the thumb to the tip of the little finger. In ancient times, a span was considered to be half a cubit. Sometimes the distinction is made between the great span or full span (thumb to little finger) and little span or short span (thumb to index finger, or index finger to little finger). History Ancient Greek texts show that the span was used as a fixed measure in ancient Greece since at least archaic period. The word ''spithame'' (Greek: "σπιθαμή"), "span", is attested in the work of Herodotus in the 5th century BC; however, the span was used in Greece long before that, since the word ''trispithamos'' (Greek: "τρισπίθαμος"), "three spans long", occurs as early as the 8th century BC in Hesiod.

Analysis Of Parallel Algorithms
In computer science, the analysis of parallel algorithms is the process of finding the computational complexity of algorithms executed in parallel – the amount of time, storage, or other resources needed to execute them. In many respects, analysis of parallel algorithms is similar to the analysis of sequential algorithms, but is generally more involved because one must reason about the behavior of multiple cooperating threads of execution. One of the primary goals of parallel analysis is to understand how a parallel algorithm's use of resources (speed, space, etc.) changes as the number of processors is changed. Background A so-called work-time (WT) (sometimes called work-depth, or work-span) framework was originally introduced by Shiloach and Vishkin for conceptualizing and describing parallel algorithms. In the WT framework, a parallel algorithm is first described in terms of parallel rounds. For each round, the operations to be performed are characterized, but several issue ...

Denard Span
Keiunta Denard Span (born February 27, 1984) is an American former professional baseball center fielder. He played in Major League Baseball (MLB) for the Minnesota Twins, Washington Nationals, San Francisco Giants, Tampa Bay Rays and Seattle Mariners. Span batted and threw left-handed and at the height of his career was known as one of the premier leadoff hitters in baseball due to his exceptional on-base percentage. Early life Span was raised by his single mother, Wanda Wilson, in Tampa. Wilson, a Federal City College graduate, supported Span and his brother, Ray, by working variously as a claims adjuster and day care operator. Their father had very little presence in their lives. As a teenager, he attended Tampa Bay Devil Rays games at Tropicana Field. He attended Tampa Catholic High School where he played football and baseball. Span won a state baseball championship with Tampa Catholic as a junior in 2001. As a senior, he hit .490. He committed to play college baseball at F ...

Span Developments
Span Developments Limited was a British property development company formed in the late 1950s by Geoffrey Townsend working in long and close partnership with Eric Lyons as consultant architect. During its most successful period in the 1960s, Span built over 2,000 homes in London, Surrey, Kent and East Sussex – mainly two- and three-bedroom single-family homes and apartment buildings. Formation Lyons and Townsend first met whilst studying architecture at evening-classes at the Regent Street Polytechnic in the 1930s. Townsend started his first architectural practice, Modern Homes, in Richmond in 1937 and Lyons joined soon after. Commissions were sparse in the immediate pre-war period but they reunited after the war, working mostly on war-damage restoration and house alteration projects and the business progressed. In 1948 they secured a contract to design a development of 24 flats in Whitton. This development, Oaklands, exhibited many of the features of their subsequent successfu ...

CME SPAN
The Standard Portfolio Analysis of Risk, or SPAN, is a system for calculating margin requirements for futures Futures may mean: Finance *Futures contract, a tradable financial derivatives contract *Futures exchange, a financial market where futures contracts are traded * ''Futures'' (magazine), an American finance magazine Music * ''Futures'' (album), a ... and options on futures. It was developed by the Chicago Mercantile Exchange in 1988. SPAN is a portfolio margining method that uses grid simulation. It calculates the likely loss in a set of derivative positions (also called a portfolio) and sets this value as the initial margin payable by the firm holding the portfolio. In this manner, SPAN provides for offsets between correlated positions and enhances margining efficiency. The CME SPAN technique, is the official Performance Bond mechanism of more than 54 exchanges and clearing organizations worldwide.

Saudi Payments Network
The Saudi Payments Network ( ar, الشبكة السعودية للمدفوعات) or mada ( ar, links=no, مدى, lit=Extend, formerly SPAN) is the only and major payment system in the kingdom of Saudi Arabia established by Ministry of Finance under the supervision of Saudi Central Bank. It connects all ATM and Point of Sale (PoS) terminals throughout the country to a central payment switch which in turn re-routes the financial transactions to the card issuer (local bank, Visa, American Express or MasterCard). All banks in Saudi Arabia are required by the Saudi Central Bank (SAMA) to issue ATM cards fully compatible with the network. All services are provided to the customer free of charge, regardless of the ATM used, its operator, or the customer's card issuer. Mada provides its services through over than 17,000 ATM machines and over 225,000 POS terminals in the Kingdom. In cooperation with global payment systems such as Visa, MasterCard, and Maestro, mada allows access to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Span (band)
SPAN was a Norwegian rock band that formed in 2000 from the ashes of two other outfits; Explicit Lyrics and Squid. Self-proclaimed as "Norwegian Turbo-Rock 'n' Roll Commandos", the band was made of Jarle Bernhoft on lead vocals and guitar, Fridtjof Nilsen on guitar, Vemund Stavnes on bass and Fredrik Wallumrød on drums. When Vemund Stavnes left in 2003, he was replaced by Kim Nordbæk. SPAN spent much of the years between 2002 and 2004 touring the UK and Norway as well as spending a brief time in the U.S. To date they have sold over 55,000 albums worldwide. In August 2005, much to their loyal fans' disappointment, SPAN announced that they were to take a break. Unfortunately there are no plans to return since a post on their website stated that the band "no longer share a common dream and ambition" and that they have "decided to end this while we are still the best of friends". Labels In the Summer of 2002, the band signed to Island Records, recording their debut album at RAK ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smartphone Ad Hoc Network
Smartphone ad hoc networks (SPANs; also ''smart phone ad hoc networks'') are wireless ad hoc networks that use smartphones. Once embedded with ad hoc networking technology, a group of smartphones in close proximity can together create an ad hoc network. Smart phone ad hoc networks use the existing hardware (primarily Bluetooth and Wi-Fi) in commercially available smartphones to create peer-to-peer networks without relying on cellular carrier networks, wireless access points, or traditional network infrastructure. Wi-Fi SPANs use the mechanism behind Wi-Fi ad-hoc mode, which allows phones to talk directly among each other, through a transparent neighbor and route discovery mechanism. SPANs differ from traditional hub and spoke networks, such as Wi-Fi Direct, in that they support multi-hop routing (ad hoc routing) and relays and there is no notion of a group leader, so peers can join and leave at will without destroying the network. Spans are useful under circumstances when the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Span (engineering)
Span is the distance between two intermediate supports for a structure, e.g. a beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the stress) will quadruple, and deflection will increase by a factor of sixteen. For long-distance rope spa ...

Port Mirroring
Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM). Port mirroring on a Cisco Systems switch is generally referred to as ''Switched Port Analyzer'' (SPAN) or ''Remote Switched Port Analyzer'' (RSPAN). Other vendors have different names for it, such as ''Roving Analysis Port'' (RAP) on 3Com 3Com Corporation was an American digital electronics manufacturer best known for its computer network products. The company was co-founded in 1979 by Robert Metcalfe, Howard Charney and others. Bill Krause joined as President in 1981. Metcalfe ex ... switches.

Span And Div
In HTML, div and span tags are elements used to define parts of a document, so that they are identifiable when a unique classification is necessary. Where other HTML elements such as p (paragraph), em (emphasis), and so on, accurately represent the semantics of the content, the additional use of span and div tags leads to better accessibility for readers and easier maintainability for authors. Where no existing HTML element is applicable, span and div can valuably represent parts of a document so that HTML attributes such as class, id, lang, or dir can be applied. span represents an inline portion of a document, for example words within a sentence. div represents a block-level portion of a document such as a few paragraphs, or an image with its caption. Neither element has any meaning in itself, but they allow semantic attributes (e.g. lang="en-US"), CSS styling (e.g., color and typography), or client-side scripting (e.g., animation, hiding, and augmentation) to be applied. ...
