Grade (education)
Grading in education is the process of applying standardized measurements for varying levels of achievements in a course. Grades can be assigned as letters (usually A through F), as a range (for example, 1 to 6), as a percentage, or as a number out of a possible total (often out of 100). In some countries, grades are averaged to create a grade point average (GPA). GPA is calculated by using the number of grade points a student earns in a given period of time. GPAs are often calculated for high school, undergraduate, and graduate students, and can be used by potential employers or educational institutions to assess and compare applicants. A cumulative grade point average (CGPA), sometimes referred to as just GPA, is a measure of performance for all of a student's courses. History Yale University historian George Wilson Pierson writes: "According to tradition the first grades issued at Yale (and possibly the first in the country) were given out in the year 1785, when Pres ...

Octane Rating
An octane rating, or octane number, is a standard measure of a Liquid fuel, fuel's ability to withstand Compression ratio, compression in an internal combustion engine without Engine knocking, detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression Petrol engine, gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (bouldering)
In the sport of bouldering, problems are assigned technical grades according to several established systems, which are often distinct from those used in roped climbing. Bouldering grade systems vary widely in use and include the Hueco "V" grades (known as the V-scale), Fontainebleau technical grades, route colors, Peak District grades, and British technical grades. Historically, the three-level "B" system and even the Yosemite Decimal System (sometimes with a "B" prepended, as in "B5.12") were also used. Gill "B" system The B system conceived by John Gill in the 1950s was a universal rating scheme for bouldering, having three categories: "B1" was defined as "... the highest level of difficulty in traditional roped climbing", "B2" was harder than B1, or "bouldering level", and the grade "B3" designated a route ascended only once, although tried by others on several occasions. When a B3 was ascended a second time, it was reclassified as a B2, or B1. Gill's idea was to attra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (climbing)
In rock climbing, mountaineering, and other climbing disciplines, climbers give a grade to a climbing route or boulder problem, intended to describe concisely the difficulty and danger of climbing it. Different types of climbing (such as sport climbing, bouldering or ice climbing) each have their own grading systems, and many nationalities developed their own, distinctive grading systems. There are a number of factors that contribute to the difficulty of a climb, including the technical difficulty of the moves, the strength, stamina and level of commitment required, and the difficulty of protecting the climber. Different grading systems consider these factors in different ways, so no two grading systems have an exact one-to-one correspondence. Climbing grades are inherently subjective.Reynolds Sagar, Heather, 2007, ''Climbing your best: training to maximize your performance'', Stackpole Books, UK, 9. They may be the opinion of one or a few climbers, often the first ascensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adjective
In linguistics, an adjective ( abbreviated ) is a word that generally modifies a noun or noun phrase or describes its referent. Its semantic role is to change information given by the noun. Traditionally, adjectives were considered one of the main parts of speech of the English language, although historically they were classed together with nouns. Nowadays, certain words that usually had been classified as adjectives, including ''the'', ''this'', ''my'', etc., typically are classed separately, as determiners. Here are some examples: * That's a funny idea. ( attributive) * That idea is funny. ( predicative) * * The good, the bad, and the funny. (substantive) Etymology ''Adjective'' comes from Latin ', a calque of grc, ἐπίθετον ὄνομα, epítheton ónoma, additional noun (whence also English ''epithet''). In the grammatical tradition of Latin and Greek, because adjectives were inflected for gender, number, and case like nouns (a process called declension), ...

Indo-European Ablaut
In linguistics, the Indo-European ablaut (, from German '' Ablaut'' ) is a system of apophony (regular vowel variations) in the Proto-Indo-European language (PIE). An example of ablaut in English is the strong verb ''sing, sang, sung'' and its related noun ''song'', a paradigm inherited directly from the Proto-Indo-European stage of the language. Traces of ablaut are found in all modern Indo-European languages, though its prevalence varies greatly. History of the concept The phenomenon of Indo-European ablaut was first recorded by Sanskrit grammarians in the later Vedic period (roughly 8th century BCE), and was codified by Pāṇini in his '' Aṣṭādhyāyī'' (4th century BCE), where the terms ' and '' '' were used to describe the phenomena now known respectively as the ''full grade'' and ''lengthened grade''.Burrow, §2.1. In the context of European languages, the phenomenon was first described in the early 18th century by the Dutch linguist Lambert ten Kate, in h ...

Vowel Gradation
In linguistics, apophony (also known as ablaut, (vowel) gradation, (vowel) mutation, alternation, internal modification, stem modification, stem alternation, replacive morphology, stem mutation, internal inflection etc.) is any Alternation (linguistics), alternation within a word that indicates grammar, grammatical information (often inflectional). Description Apophony is exemplified in English language, English as the ''internal'' vowel alternations that produce such related words as * sng, sng, sng, sng * bnd, bnd * bld, bld * brd, brd * dm, dm * fd, fd * l, l * rse, rse, rsen * wve, wve * ft, ft * gse, gse * tth, tth The difference in these vowels marks variously a difference in Grammatical tense, tense or Grammatical aspect, aspect (e.g. ''sing/sang/sung''), Transitive verb, transitivity (''rise/raise''), part of speech (''sing/song''), or grammatical number (''goose/geese''). That these sound alternations function grammatically can be seen as they are often equivalent to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graded Algebra
In mathematics, in particular abstract algebra, a graded ring is a ring such that the underlying additive group is a direct sum of abelian groups R_i such that R_i R_j \subseteq R_. The index set is usually the set of nonnegative integers or the set of integers, but can be any monoid. The direct sum decomposition is usually referred to as gradation or grading. A graded module is defined similarly (see below for the precise definition). It generalizes graded vector spaces. A graded module that is also a graded ring is called a graded algebra. A graded ring could also be viewed as a graded \Z-algebra. The associativity is not important (in fact not used at all) in the definition of a graded ring; hence, the notion applies to non-associative algebras as well; e.g., one can consider a graded Lie algebra. First properties Generally, the index set of a graded ring is assumed to be the set of nonnegative integers, unless otherwise explicitly specified. This is the case in this a ...

Graded Vector Space
In mathematics, a graded vector space is a vector space that has the extra structure of a '' grading'' or a ''gradation'', which is a decomposition of the vector space into a direct sum of vector subspaces. Integer gradation Let \mathbb be the set of non-negative integers. An \mathbb-graded vector space, often called simply a graded vector space without the prefix \mathbb, is a vector space together with a decomposition into a direct sum of the form : V = \bigoplus_ V_n where each V_n is a vector space. For a given ''n'' the elements of V_n are then called homogeneous elements of degree ''n''. Graded vector spaces are common. For example the set of all polynomials in one or several variables forms a graded vector space, where the homogeneous elements of degree ''n'' are exactly the linear combinations of monomials of degree ''n''. General gradation The subspaces of a graded vector space need not be indexed by the set of natural numbers, and may be indexed by the ...

Graded Poset
In mathematics, in the branch of combinatorics, a graded poset is a partially-ordered set (poset) ''P'' equipped with a rank function ''ρ'' from ''P'' to the set N of all natural numbers. ''ρ'' must satisfy the following two properties: * The rank function is compatible with the ordering, meaning that for all ''x'' and ''y'' in the order, if ''x'' < ''y'' then ''ρ''(''x'') < ''ρ''(''y''), and * The rank is consistent with the covering relation of the ordering, meaning that for all ''x'' and ''y'', if ''y'' covers ''x'' then ''ρ''(''y'') = ''ρ''(''x'') + 1. The value of the rank function for an element of the poset is called its rank. Sometimes a graded poset is called a ranked poset but that phrase has other meanings; see Ranked poset. A rank or ...

Graded (mathematics)
In mathematics, the term “graded” has a number of meanings, mostly related: In abstract algebra, it refers to a family of concepts: * An algebraic structure X is said to be I-graded for an index set I if it has a gradation or grading, i.e. a decomposition into a direct sum X = \bigoplus_ X_i of structures; the elements of X_i are said to be "homogeneous of degree ''i'' ". ** The index set I is most commonly \N or \Z, and may be required to have extra structure depending on the type of X. ** Grading by \Z_2 (i.e. \Z/2\Z) is also important; see e.g. signed set (the \Z_2-graded sets). ** The trivial (\Z- or \N-) gradation has X_0 = X, X_i = 0 for i \neq 0 and a suitable trivial structure 0. ** An algebraic structure is said to be doubly graded if the index set is a direct product of sets; the pairs may be called "bidegrees" (e.g. see Spectral sequence). * A I-graded vector space or graded linear space is thus a vector space with a decomposition into a direct sum V = ...

Grade (angle)
In trigonometry, the gradian, also known as the gon (from grc, γωνία, gōnía, angle), grad, or grade, is a unit of measurement of an angle, defined as one hundredth of the right angle; in other words, there are 100 gradians in 90 degrees.Harris, J. W. and Stocker, H. Handbook of Mathematics and Computational Science. New York: Springer-Verlag, p. 63, 1998. It is equivalent to of a turn, of a degree, or of a radian. Measuring angles in gradians is said to employ the ''centesimal'' system of angular measurement, initiated as part of metrication and decimalisation efforts. In continental Europe, the French word ''centigrade'', also known as ''centesimal minute of arc'', was in use for one hundredth of a grade; similarly, the ''centesimal second of arc'' was defined as one hundredth of a centesimal arc-minute, analogous to decimal time and the sexagesimal minutes and seconds of arc. The chance of confusion was one reason for the adoption of the term '' Celsius'' t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
