Flag Of Algeria
The national flag of Algeria ( ar, علم الجزائر; ber, ⴰⵏⴰⵢ ⴰⴷⵣⴰⵢⵔⵉ, Anay azzayri) consists of two equal vertical bars, green and white, charged in the center with a red star and crescent, a symbol of Islam as the nation's prominent faith. The flag was adopted on 3 July 1962. A similar version was used by the Algerian government in exile from 1958 to 1962. The Western blazon is ''per pale vert and argent; a crescent and star gules''. History The Barbary pirates of Ottoman Algeria between the 15th and 17th century widely used flags that were emblazoned with one or more crescents. These could however vary greatly in color, with dark red, black, green and white being in use. Besides these, Algerian pirates also used various flags in plain color, such as plain black ones signalling death. Less often, Algerian flags of this time also carried other motifs, such as suns, stars and crossed swords. It is also known that city of Algiers used an oran ...

Kingdom Of Tlemcen
The Kingdom of Tlemcen or Zayyanid Kingdom of Tlemcen ( ar, الزيانيون) was a Berber kingdom in what is now the northwest of Algeria. Its territory stretched from Tlemcen to the Chelif bend and Algiers, and at its zenith reached Sijilmasa and the Moulouya River in the west, Tuat to the south and the Soummam in the east.الدولة الزيانية في عهد يغمراسن: دراسة تاريخية وحضارية 633 هـ - 681 هـ / 1235 م - 1282 مخالد بلع ربي Al Manhal [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
:en:Pantone
Pantone LLC (stylized as PANTONE) is a limited liability company headquartered in Carlstadt, New Jersey. The company is best known for its Pantone Matching System (PMS), a proprietary color space used in a variety of industries, notably graphic design, fashion design, product design, printing and manufacturing and supporting the management of color from design to production, in physical and digital formats, among coated and uncoated materials, cotton, polyester, nylon and plastics. X-Rite, a supplier of color measurement instruments and software, purchased Pantone for US$180 million in October 2007, and was itself acquired by Danaher Corporation in 2012. Overview Pantone began in New Jersey in the 1950s as the commercial printing company of brothers Mervin and Jesse Levine, M & J Levine Advertising. In 1956, its founders, both advertising executives, hired recent Hofstra University graduate Lawrence Herbert as a part-time employee. Herbert used his chemistry knowledge to sys ...

:en:CMYK Color Model
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation ''CMYK'' refers to the four ink plates used: cyan, magenta, yellow, and key (black). The CMYK model works by partially or entirely masking colors on a lighter, usually white, background. The ink reduces the light that would otherwise be reflected. Such a model is called ''subtractive'' because inks "subtract" the colors red, green and blue from white light. White light minus red leaves cyan, white light minus green leaves magenta, and white light minus blue leaves yellow. In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, black is the absence of light. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of col ...

:en:Hexadecimal
In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15. Software developers and system designers widely use hexadecimal numbers because they provide a human-friendly representation of binary-coded values. Each hexadecimal digit represents four bits (binary digits), also known as a nibble (or nybble). For example, an 8-bit byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal. In mathematics, a subscript is typically used to specify the base. For example, the decimal value would be expressed in hexadecimal as . In programming, a number of no ...

:en:RGB Color Model
The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue. The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors. RGB is a ''device-dependent'' color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual red, green, and blue levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same ''color'' across ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wavelength
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The inverse of the wavelength is called the spatial frequency. Wavelength is commonly designated by the Greek letter '' lambda'' (λ). The term ''wavelength'' is also sometimes applied to modulated waves, and to the sinusoidal envelopes of modulated waves or waves formed by interference of several sinusoids. Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Wavelength depends on the medium (for example, vacuum, air, or water) tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Ensign
A naval ensign is an ensign (maritime flag) used by naval ships of various countries to denote their nationality. It can be the same or different from a country's civil ensign or state ensign. It can also be known as a war ensign. A large version of a naval ensign that is flown on a warship's mast just before going into battle is called a battle ensign. An ensign differs from a jack, which is flown from a jackstaff at the bow of a vessel. Most countries have only one national flag and ensign for all purposes. In other countries, a distinction is made between the land flag and the civil, state and naval ensigns. The British ensigns, for example, differ from the flag used on land (the Union Flag) and have different versions of plain and defaced Red and Blue ensigns for civilian and state use, as well as the naval ensign ( White Ensign). Some naval ensigns differ in shape from the national flag, such as the Nordic naval ensigns, which have ' tongues'. Countries having spe ...

Flag Terminology
Flag terminology is the nomenclature, or system of terms, used in vexillology, the study of flags, to describe precisely the parts, patterns, and other attributes of flags and their display. Flag types Flag elements Basic patterns Flags often inherit traits seen in traditional European heraldry designs and as a result patterns often share names. Techniques in flag display Illustrations Flag illustrations generally depict flags flying from the observer's point of view from left to right, the view known as the obverse (or "front"); the other side is the reverse (or "back"). There are some exceptions, notably some Islamic flags inscribed in Arabic, which is written from right to left; for these the obverse is defined as the side with the hoist to the observer's right.
