Quincuncial (botany)
A quincunx () is a geometric pattern consisting of five points arranged in a cross, with four of them forming a square or rectangle and a fifth at its center. The same pattern has other names, including "in saltire" or "in cross" in heraldry (depending on the orientation of the outer square), the five-point stencil in numerical analysis, and the five dots tattoo. It forms the arrangement of five units in the pattern corresponding to the five-spot on six-sided dice, playing cards, and dominoes. It is represented in Unicode as or (for the die pattern) . Historical origins of the name The quincunx was originally a coin issued by the Roman Republic c. 211–200 BC, whose value was five twelfths (''quinque'' and ''uncia'') of an as, the Roman standard bronze coin. On the Roman quincunx coins, the value was sometimes indicated by a pattern of five dots or pellets. However, these dots were not always arranged in a quincunx pattern.

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the first and foundational historical dictionary of the English language, published by Oxford University Press (OUP). It traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. Work began on the dictionary in 1857, but it was only in 1884 that it began to be published in unbound fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 bound volumes. In 1933, the title ''The Oxford English Dictionary'' fully replaced the former name in all occurrences in its reprinting as 12 volumes with a one-v ...

Finite Difference
A finite difference is a mathematical expression of the form . If a finite difference is divided by , one gets a difference quotient. The approximation of derivatives by finite differences plays a central role in finite difference methods for the numerical solution of differential equations, especially boundary value problems. The difference operator, commonly denoted \Delta is the operator that maps a function to the function \Delta /math> defined by :\Delta x)= f(x+1)-f(x). A difference equation is a functional equation that involves the finite difference operator in the same way as a differential equation involves derivatives. There are many similarities between difference equations and differential equations, specially in the solving methods. Certain recurrence relations can be written as difference equations by replacing iteration notation with finite differences. In numerical analysis, finite differences are widely used for approximating derivatives, and the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multisample Anti-aliasing
Multisample anti-aliasing (MSAA) is a type of spatial anti-aliasing, a technique used in computer graphics to remove jaggies. Definition The term generally refers to a special case of supersampling. Initial implementations of full-scene anti-aliasing ( FSAA) worked conceptually by simply rendering a scene at a higher resolution, and then downsampling to a lower-resolution output. Most modern GPUs are capable of this form of anti-aliasing, but it greatly taxes resources such as texture, bandwidth, and fillrate. (If a program is highly TCL-bound or CPU-bound, supersampling can be used without much performance hit.) According to the OpenGL GL_ARB_multisample specification, "multisampling" refers to a specific optimization of supersampling. The specification dictates that the renderer evaluate the fragment program once per pixel, and only "truly" supersample the depth and stencil values. (This is not the same as supersampling but, by the OpenGL 1.5 specification, the definition ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Graphics
Computer graphics deals with generating images with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research. Some topics in computer graphics include user interface design, sprite graphics, rendering, ray tracing, geometry processing, computer animation, vector graphics, 3D modeling, shaders, GPU design, implicit surfaces, visualization, scientific c ...

Coat Of Arms Of Portugal
The coat of arms of Portugal is the main heraldic insignia of Portugal. The present model was officially adopted on 30 June 1911, along with the present model of the Flag of Portugal. It is based on the coat of arms used by the Portuguese Kingdom since the Middle Ages. The coat of arms of Portugal is popularly referred as the ''Quinas'' (a ''quina'' being a group of five things). The current design of the coat of arms The present model of the coat of arms of Portugal was designed by the painter Columbano, member of the commission appointed on the 15 October 1910 to present the project for a new National Flag, following the establishing of the Portuguese republic on the 5 October 1910. The models chosen by the commission were approved by the Provisional Government of the Republic on the 29 November 1910, confirmed by the Constituent Assembly through the decree of 19 June 1911, with its details being specified in the ''Diário do Governo'' (official journal) no 150 of 30 June 191 ...

Republic Of Yucatán
The Republic of Yucatán ( es, República de Yucatán) was a sovereign state during two periods of the nineteenth century. The first Republic of Yucatán, founded May 29, 1823, willingly joined the Mexican federation as the Federated Republic of Yucatán on December 23, 1823, less than seven months later. The second Republic of Yucatán began in 1841, with its declaration of independence from the Centralist Republic of Mexico. It remained independent for seven years, after which it rejoined the United Mexican States. The area of the former republic includes the modern Mexican states of Yucatán, Campeche and Quintana Roo. The Republic of Yucatán usually refers to the Second Republic (1841–1848). The Republic of Yucatán was governed by the Constitution of 1841 which guaranteed individual rights, religious freedom and what was then a new legal form called '' amparo'' ( en, protection). The 1847 Caste War caused the Republic of Yucatán to request military aid from Mexico. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Of The Solomon Islands
The flag of Solomon Islands consists of a thin yellow diagonal stripe divided diagonally from the lower hoist-side corner, with a blue upper triangle and green lower triangle, and the canton charged with five white stars. Adopted in 1977 to replace the British Blue Ensign defaced with the arms of the protectorate, it has been the flag of Solomon Islands since 18 November of that year, eight months before the country gained independence. Although the number of provinces has since increased, the number of stars on the flag that originally represented them remained unchanged. History British protectorate The Germans and the British agreed to partition the modern-day Solomon Islands in 1886, with the latter taking control of the southern section. Seven years later, in 1893, they declared this area a protectorate within their colonial empire. At the turn of the 20th century, Germany subsequently gave up their northern part to the United Kingdom in exchange for the latter's ...

Saltire
A saltire, also called Saint Andrew's Cross or the crux decussata, is a heraldic symbol in the form of a diagonal cross, like the shape of the letter X in Roman type. The word comes from the Middle French ''sautoir'', Medieval Latin ''saltatoria'' (" stirrup"). From its use as field sign, the saltire came to be used in a number of flags, in the 16th century for Scotland and Burgundy, in the 18th century also as the ensign of the Russian Navy, and for Ireland. Notable 19th-century usage includes some of the flags of the Confederate States of America. It is also used in the flag of Jamaica and on seals, and as a heraldic charge in coats of arms. The term saltirewise or in saltire refers to heraldic charges arranged as a diagonal cross. The shield may also be divided per saltire, i.e. diagonally. A warning sign in the shape of a saltire is also used to indicate the point at which a railway line intersects a road at a level crossing. Heraldry and vexillology The saltire i ...
