Glyph
A glyph () is any kind of purposeful mark. In typography, a glyph is "the specific shape, design, or representation of a character". It is a particular graphical representation, in a particular typeface, of an element of written language. A grapheme, or part of a grapheme (such as a diacritic), or sometimes several graphemes in combination (a composed glyph) can be represented by a glyph. Glyphs, graphemes and characters In most languages written in any variety of the Latin alphabet except English, the use of diacritics to signify a sound mutation is common. For example, the grapheme requires two glyphs: the basic and the grave accent . In general, a diacritic is regarded as a glyph, even if it is contiguous with the rest of the character like a cedilla in French, Catalan or Portuguese, the ogonek in several languages, or the stroke on a Polish " Ł". Although these marks originally had no independent meaning, they have since acquired meaning in the field of mathematic ...

Brāhmī Script
Brahmi (; ; ISO: ''Brāhmī'') is a writing system of ancient South Asia. "Until the late nineteenth century, the script of the Aśokan (non-Kharosthi) inscriptions and its immediate derivatives was referred to by various names such as 'lath' or 'Lat', 'Southern Aśokan', 'Indian Pali', 'Mauryan', and so on. The application to it of the name Brahmi 'sc. lipi'' which stands at the head of the Buddhist and Jaina script lists, was first suggested by T rriende Lacouperie, who noted that in the Chinese Buddhist encyclopedia ''Fa yiian chu lin'' the scripts whose names corresponded to the Brahmi and Kharosthi of the ''Lalitavistara'' are described as written from left to right and from right to left, respectively. He therefore suggested that the name Brahmi should refer to the left-to-right 'Indo-Pali' script of the Aśokan pillar inscriptions, and Kharosthi to the right-to-left 'Bactro-Pali' script of the rock inscriptions from the northwest." that appeared as a fully developed scrip ...

List Of Musical Symbols
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which fingers, keys, or pedals are to be used, whether a string instrument should be bowed or plucked, or whether the bow of a string instrument should move up or down). Lines Clefs A clef assigns one particular pitch to one particular line of the staff on which it is placed. This also effectively defines the pitch range or tessitura of the music on that staff. A clef is usually the leftmost symbol on a staff, although a different clef may appear elsewhere to indicate a change in register. Historically, clefs could be placed on any line on a staff (or even on a space), but modern notation a ...

Nazar (amulet)
A nazar (from Arabic , word deriving from Arabic, meaning ''sight'', ''surveillance'', ''attention'', and other related concepts) is an eye-shaped amulet believed to protect against the evil eye. The term is also used in Azerbaijani, Bengali, Hebrew, Hindi, Kurdish, Pashto, Persian, Punjabi, Turkish, Urdu and other languages. In Turkey, it is known by the name nazar boncuğu (the latter word being a derivative of ''boncuk'', "bead" in Turkic, and the former borrowed from Arabic), in Greece is known as mati ( the evil eye). In Persian and Afghan folklore, it is called a cheshm nazar ( fa, چشم نظر) or nazar qurbāni ( fa, نظرقربانی, links=no). In India and Pakistan, the Hindi-Urdu slogan '' Chashm-e-Baddoor'' is used to ward off the evil eye. In the Indian subcontinent, the phrase "Nazar lag gai" is used to indicate that one has been affected by the evil eye. It is commonly believed that the evil eye can be given in the guise of a compliment, signifying its c ...

Chromebook
A Chromebook (sometimes stylized in lowercase as chromebook) is a laptop or tablet running the Linux-based ChromeOS as its operating system. Initially designed to heavily rely on web applications for tasks using the Google Chrome browser, Chromebooks have since expanded to be able to run Android and full-fledged Linux apps since 2017 and 2018, respectively. All supported apps can be installed and launched alongside each other. Chromebooks can work offline; applications like Gmail, Google Calendar, Google Keep, and Google Drive synchronize data when reconnecting to the Internet. Google Play video content is available offline using the Google Play Movies & TV extension with the Chrome browser. The first Chromebooks shipped on June 15, 2011. Other form factors include Chromebox desktops, Chromebase, which places the computer in an all-in-one unit, an HDMI stick PC called a Chromebit, and Chromebook tablets. In 2020, Chromebooks outsold Apple Macs for the first time by taking ...

Radio Button
A radio button or option button is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items. Radio buttons are arranged in groups of two or more and displayed on screen as, for example, a list of circular holes that can contain white space (for unselected) or a dot (for selected). Each radio button is normally accompanied by a label describing the choice that the radio button represents. The choices are mutually exclusive; when the user selects a radio button, any previously selected radio button in the same group becomes deselected (making it so only one can be selected). Selecting a radio button is done by clicking the mouse on (or touching the screen over) the button, or the caption, or by using a keyboard shortcut. It is possible that initially none of the radio buttons in a group ...

Circle
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius. Usually, the radius is required to be a positive number. A circle with r=0 (a single point) is a degenerate case. This article is about circles in Euclidean geometry, and, in particular, the Euclidean plane, except where otherwise noted. Specifically, a circle is a simple closed curve that divides the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is only the boundary and the whole figure is called a '' disc''. A circle may also be defined as a special ki ...

Hadamard Product (matrices)
In mathematics, the Hadamard product (also known as the element-wise product, entrywise product or Schur product) is a binary operation that takes two matrices of the same dimensions and produces another matrix of the same dimension as the operands, where each element is the product of elements of the original two matrices. It is to be distinguished from the more common matrix product. It is attributed to, and named after, either French mathematician Jacques Hadamard or German Russian mathematician Issai Schur. The Hadamard product is associative and distributive. Unlike the matrix product, it is also commutative. Definition For two matrices and of the same dimension , the Hadamard product A \circ B (or A \odot B) is a matrix of the same dimension as the operands, with elements given by :(A \circ B)_ = (A \odot B)_ = (A)_ (B)_. For matrices of different dimensions ( and , where or ), the Hadamard product is undefined. Example For example, the Hadamard product for a 3  ...

XNOR Gate
The XNOR gate (sometimes XORN'T, ENOR, EXNOR or NXOR and pronounced as Exclusive NOR. Alternatively XAND, pronounced Exclusive AND) is a digital logic gate whose function is the logical complement of the Exclusive OR (XOR gate, XOR) gate. It is equivalent to the logical connective (\leftrightarrow) from mathematical logic, also known as the material biconditional. The two-input version implements logical equality, behaving according to the truth table to the right, and hence the gate is sometimes called an "equivalence gate". A high output (1) results if both of the inputs to the gate are the same. If one but not both inputs are high (1), a low output (0) results. The Boolean algebra, algebraic notation used to represent the XNOR operation is S = A \odot B. The algebraic expressions (A + \overline) \cdot (\overline + B) and A \cdot B + \overline A \cdot \overline B both represent the XNOR gate with inputs ''A'' and ''B''. Symbols There are logic gate#Symbols, two symbols for XN ...
