Standardization
Standardization (American English) or standardisation (British English) is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, efficiency, and quality. It can also facilitate a normalization of formerly custom processes. In social sciences, including economics, the idea of ''standardization'' is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions. Divergent national standards impose costs on consumers and can be a form of non-tariff trade barrier. History Early examples Standard weights and measures were developed by the Indus Valley civilization.Iwata, Shigeo (2008), "Weights and Measures in the Indus Valley", ''Encyclopaedia of the History ...

Technical Standard
A technical standard is an established Social norm, norm or requirement for a repeatable technical task which is applied to a common and repeated use of rules, conditions, guidelines or characteristics for products or related processes and production methods, and related management systems practices. A technical standard includes definition of terms; classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength. It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes, and practices. In contrast, a custom, convention, company product, corporate standard, and so forth that becomes generally accepted and dominant is often called a ''de facto'' standar ...

Safety
Safety is the state of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk. Meanings The word 'safety' entered the English language in the 14th century. It is derived from Latin , meaning uninjured, in good health, safe. There are two slightly different meanings of "safety". For example, " home safety" may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants. Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers are left to conclude whether they comprise a redundancy. This confuses the uniqueness that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quality (business)
In business, engineering, and manufacturing, quality – or high quality – has a pragmatic interpretation as the non-inferiority or wikt:superiority, superiority of something (goods or service (economics), services); it is also defined as being suitable for the intended purpose (fitness for purpose) while satisfying customer expectations. Quality is a perceptual, conditional, and somewhat subjectivity, subjective attribute and may be understood differently by different people. Consumers may focus on the Acceptance testing, specification quality of a product/service, or how it compares to competitors in the marketplace. Producers might measure the Conformance testing, conformance quality, or degree to which the product/service was produced correctly. Support personnel may measure quality in the degree that a product is wikt:reliable, reliable, Maintainability, maintainable, or sustainability, sustainable. In such ways, the subjectivity of quality is rendered objectivity (philosoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British English
British English is the set of Variety (linguistics), varieties of the English language native to the United Kingdom, especially Great Britain. More narrowly, it can refer specifically to the English language in England, or, more broadly, to the collective dialects of English throughout the United Kingdom taken as a single umbrella variety, for instance additionally incorporating Scottish English, Welsh English, and Northern Irish English. Tom McArthur (linguist), Tom McArthur in the Oxford English Dictionary, Oxford Guide to World English acknowledges that British English shares "all the ambiguities and tensions [with] the word 'British' and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity". Variations exist in formal (both written and spoken) English in the United Kingdom. For example, the adjective ''wee'' is almost exclusively used in parts of Scotland, north-east England, Northern Ireland, Ireland ...

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color, from white to black, but is most often found as gray, brown, grayish brown and light green to rusty redW.L. Roberts, T.J.

Maudslay Screw-cutting Lathes Of Circa 1797 And 1800
Henry Maudslay ( pronunciation and spelling) (22 August 1771 – 14 February 1831) was an English machine tool innovator, tool and die maker, and inventor. He is considered a founding father of machine tool technology. His inventions were an important foundation for the Industrial Revolution. Maudslay's invention of a metal lathe to cut metal, circa 1800, enabled the manufacture of standard screw thread sizes. Standard screw thread sizes allowed interchangeable parts and the development of mass production. Early life Maudslay was the fifth of seven children of Henry Maudslay, a wheelwright in the Royal Engineers, and Margaret (''nee'' Whitaker), the young widow of Joseph Laundy. His father was wounded in action and so in 1756 became an 'artificer' at the Royal Arsenal, Woolwich (then in Kent), where he remained until 1776 and died in 1780. The family lived in an alley that no longer exists, off Beresford Square, between Powis Street and Beresford Street. Career Maudsla ...

Decimal
The decimal numeral system (also called the base-ten positional numeral system and denary or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers (''decimal fractions'') of the Hindu–Arabic numeral system. The way of denoting numbers in the decimal system is often referred to as ''decimal notation''. A decimal numeral (also often just ''decimal'' or, less correctly, ''decimal number''), refers generally to the notation of a number in the decimal numeral system. Decimals may sometimes be identified by a decimal separator (usually "." or "," as in or ). ''Decimal'' may also refer specifically to the digits after the decimal separator, such as in " is the approximation of to ''two decimals''". Zero-digits after a decimal separator serve the purpose of signifying the precision of a value. The numbers that may be represented in the decimal system are the decimal fractions. That is, fractions of the form , w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Numeral System
A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method for representing numbers that uses only two symbols for the natural numbers: typically "0" ( zero) and "1" ( one). A ''binary number'' may also refer to a rational number that has a finite representation in the binary numeral system, that is, the quotient of an integer by a power of two. The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because of the simplicity of the language and the noise immunity in physical implementation. History The modern binary number system was studied in Europe in the 16th and 17th centuries by Thomas Harrio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surkotada
Surkotada is an archaeological site located in Rapar Taluka of Kutch district, Gujarat, India which belongs to the Indus Valley civilisation (IVC). It is a smaller fortified IVC site with in area. Location and environment The site at Surkotada is located north-east of Bhuj, in the district of Kutch, Gujarat. The ancient mound stands surrounded by an undulating rising ground clustered by small sandstone hills. These hills are covered with red laterite soil giving the entire region a reddish-brown colour. The vegetation is scarce and consists of cactus, small babul and pilu trees and thorny shrubs. These give green patches to the red environment. The mound was discovered in 1964 by J. P. Joshi of the Archaeological Survey of India. The mound is higher on the western side and lower on the eastern side and has an average height of . In the ancient days, a river 750 m (½ mi) wide flowed past the north-eastern side of the site. This river, which emptied into the Littl ...

Chanhudaro
Chanhu-daro , a shorter form of Chanhun-jo-daro which in Sindhi means "the mound of Chanhun", is an archaeological site belonging to the Indus Valley civilization. The site is located south of Mohenjo-daro, now in Sindh, Pakistan. The settlement was inhabited between 4000 and 1700 BCE, and is considered to have been a centre for manufacturing carnelian beads. This site is a group of three low mounds that excavations has shown were parts of a single settlement, approximately 7 hectares in size. Chanhudaro was first excavated by N. G. Majumdar in March, 1931, and again during winter field session of 1935-36 by the American School of Indic and Iranian Studies and the Museum of Fine Arts, Boston team led by Ernest John Henry Mackay. Prof. W. Norman Brown of the University of Pennsylvania was instrumental in enabling the funds for this project. After the independence of Pakistan, Mohammed Rafique Mughal also did exploratory work in the area. Since 2015 the archaeological exca ...

Central Asia
Central Asia is a region of Asia consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian language, Persian suffix "-stan" (meaning ) in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Volga Tatars, Tatars, Turkmens, ...
