Stanza
In poetry, a stanza (; from Italian language, Italian ''stanza'' , "room") is a group of lines within a poem, usually set off from others by a blank line or Indentation (typesetting), indentation. Stanzas can have regular rhyme scheme, rhyme and Metre (poetry), metrical schemes, but they are not required to have either. There are many different : Stanzaic form, forms of stanzas. Some stanzaic forms are simple, such as four-line quatrains. Other forms are more complex, such as the Spenserian stanza. Fixed verse, Fixed verse poems, such as sestinas, can be defined by the number and form of their stanzas. The stanza has also been known by terms such as ''batch'', ''fit'', and ''stave''. The term ''stanza'' has a similar meaning to ''strophe'', though ''strophe'' sometimes refers to an irregular set of lines, as opposed to regular, rhymed stanzas. Even though the term "stanza" is taken from Italian, in the Italian language the word "strofa" is more commonly used. In music, groups of ...

Street
A street is a public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as tarmac, concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with rails, or otherwise prepared to accommodate non-pedestrian traffic. Originally, the word ''street'' simply meant a paved road ( la, via strata). The word ''street'' is still sometimes used informally as a synonym for ''road'', for example in connection with the ancient Watling Street, but city residents and urban planners draw a crucial modern distinction: a road's main function is transportation, while streets facilitate public interaction.

String Theory
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties determined by the vibrational state of the string. In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries the gravitational force. Thus, string theory is a theory of quantum gravity. String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics. String theory has contributed a number of advances to mathematical physics, which have been applied to a variety of problems in black hole physics, early universe cosmology, nuclear physics, and conde ...

Strouhal Number
In dimensional analysis, the Strouhal number (St, or sometimes Sr to avoid the conflict with the Stanton number) is a dimensionless number describing oscillating flow mechanisms. The parameter is named after Vincenc Strouhal, a Czech physicist who experimented in 1878 with wires experiencing vortex shedding and singing in the wind. The Strouhal number is an integral part of the fundamentals of fluid mechanics. The Strouhal number is often given as \text = \frac, where ''f'' is the frequency of vortex shedding, ''L'' is the characteristic length (for example, hydraulic diameter or the airfoil thickness) and ''U'' is the flow velocity. In certain cases, like heaving (plunging) flight, this characteristic length is the amplitude of oscillation. This selection of characteristic length can be used to present a distinction between Strouhal number and reduced frequency: \text = \frac, where ''k'' is the reduced frequency, and ''A'' is amplitude of the heaving oscillation.

Stanton Number
The Stanton number, ''St'', is a dimensionless number that measures the ratio of heat transferred into a fluid to the thermal capacity of fluid. The Stanton number is named after Thomas Stanton (engineer) (1865–1931). It is used to characterize heat transfer in forced convection flows. Formula St = \frac = \frac where *''h'' = convection heat transfer coefficient * ''ρ'' = density of the fluid *''cp'' = specific heat of the fluid *''u'' = velocity of the fluid It can also be represented in terms of the fluid's Nusselt, Reynolds, and Prandtl numbers: :\mathrm = \frac where * Nu is the Nusselt number; * Re is the Reynolds number; * Pr is the Prandtl number. The Stanton number arises in the consideration of the geometric similarity of the momentum boundary layer and the thermal boundary layer, where it can be used to express a relationship between the shear force at the wall (due to viscous drag) and the total heat transfer at the wall (due to thermal diffusivity).

Standard Part Function
In nonstandard analysis, the standard part function is a function from the limited (finite) hyperreal numbers to the real numbers. Briefly, the standard part function "rounds off" a finite hyperreal to the nearest real. It associates to every such hyperreal x, the unique real x_0 infinitely close to it, i.e. x-x_0 is infinitesimal. As such, it is a mathematical implementation of the historical concept of adequality introduced by Pierre de Fermat,Karin Usadi Katz and Mikhail G. Katz (2011) A Burgessian Critique of Nominalistic Tendencies in Contemporary Mathematics and its Historiography. Foundations of Science.Searxiv The authors refer to the Fermat-Robinson standard part. as well as Leibniz's Transcendental law of homogeneity. The standard part function was first defined by Abraham Robinson who used the notation ^x for the standard part of a hyperreal x (see Robinson 1974). This concept plays a key role in defining the concepts of the calculus, such as continuity, the derivati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St (terminal Emulator)
suckless.org is a free software community of programmers working on projects with a focus on minimalism, simplicity, clarity, and frugality. The group developed the dwm and wmii window managers, surf tabbed, and other programs that are said to adhere strictly to the Unix philosophy of "doing one thing and doing it well". History The suckless community was founded by Anselm R. Garbe in 2006. He became a vocal proponent of the suckless philosophy, saying that "a lot f whatwent wrong in the IT industry recently ..be recognized in order to rethink the common practice, and perhaps to think about the time when Moore's law stops being a valid assumption." The suckless manifesto deplores the common tendency for "complex, error-prone and slow software hatseems to be prevalent in the present-day software industry", and argues that a programmer's performance should not be measured by the number of lines of code they write. In October 2006, Garbe registered the domain ''suckless.org'' to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structured Text
Structured text, abbreviated as ST or STX, is one of the five languages supported by the IEC 61131-3 standard, designed for programmable logic controllers (PLCs).

Internet Stream Protocol
The Internet Stream Protocol (ST) is a family of experimental protocols first defined in Internet Experiment Note IEN-119 in 1979, and later substantially revised in RFC 1190 (ST-II) and RFC 1819 (ST2+). The protocol uses the version number 5 in the version field of the Internet Protocol header, but was never known as IPv5. The successor to IPv4 was thus named IPv6 to eliminate any possible confusion about the actual protocol in use. History The Internet Stream Protocol family was never introduced for public use, but many of the concepts available in ST are similar to later Asynchronous Transfer Mode protocols and can be found in Multiprotocol Label Switching (MPLS). They also presaged voice over IP. ST arose as the transport protocol of the Network Voice Protocol, a pioneering computer network protocol for transporting human speech over packetized communications networks, first implemented in December 1973 by Internet researcher Danny Cohen of the Information Sciences Institut ...

Seagate Technology
Seagate Technology Holdings plc is an American data storage company. It was incorporated in 1978 as Shugart Technology and commenced business in 1979. Since 2010, the company has been incorporated in Dublin, Ireland, with operational headquarters in Fremont, California, United States. Seagate developed the first 5.25-inch hard disk drive (HDD), the 5-megabyte ST-506, in 1980. They were a major supplier in the microcomputer market during the 1980s, especially after the introduction of the IBM XT in 1983. Much of their growth has come through their acquisition of competitors. In 1989, Seagate acquired Control Data Corporation's Imprimis division, the makers of CDC's HDD products. Seagate acquired Conner Peripherals in 1996, Maxtor in 2006, and Samsung's HDD business in 2011. Today, Seagate, along with its competitor Western Digital, dominates the HDD market.

Atari ST
The Atari ST is a line of personal computers from Atari Corporation and the successor to the Atari 8-bit family. The initial model, the Atari 520ST, had limited release in April–June 1985 and was widely available in July. It was the first personal computer with a bitmapped color GUI, using a version of Digital Research's GEM (desktop environment), GEM from February 1985. The Atari 1040ST, released in 1986 with 1 MB of RAM, was the first home computer with a cost-per-kilobyte of less than US$1. "ST" officially stands for "Sixteen/Thirty-two", referring to the Motorola 68000's 16-bit computing, 16-bit external bus and 32-bit computing, 32-bit internals. The system was designed by a small team led by Shiraz Shivji. Alongside the Macintosh, Amiga, Apple IIGS, and Acorn Archimedes, the ST is part of a mid-1980s generation of computers with 16- or 32-bit processors, 256 Kilobyte, KB or more of RAM, and computer mouse, mouse-controlled graphical user interfaces.

ST Connector
An optical fiber connector joins optical fibers, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all, about 100 different types of fiber optic connectors have been introduced to the market. Application Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are often assembled onto optical fiber in a supplier's manufacturing facility. However, the assembly and polishing operations involved can be performed in the field, for example, to terminate long runs at a patch panel. Optical fiber connectors are used in telephone exchanges, for customer premises wiring, and in outside plant applications to connect equipment and f ...
