Octet (music)
In music, an octet is a musical ensemble consisting of eight Musical instrument, instruments or voices, or a musical composition written for such an ensemble. Octets in classical music Octets in European classical music, classical music are one of the largest groupings of chamber music. Although eight-part scoring was fairly common for serenades and Divertimento, divertimenti in the 18th century, the word "octet" only first appeared at the beginning of the 19th century, as the title of a composition by Prince Louis Ferdinand of Prussia (1772–1806), Prince Louis Ferdinand of Prussia, whose Octet Op. 12 (published posthumously in 1808) features the piano, together with clarinet, 2 horns, 2 violins, and 2 cellos. Later octets with piano were written by Ferdinand Ries (Op. 128, 1818, with clarinet, horn, bassoon, violin, viola, cello, and double bass), Anton Rubinstein (Op. 9, 1856, with flute, clarinet, horn, violin, viola, cello, and double bass), and Paul Juon (Chamber Symphony, ...

Octet (computing)
The octet is a unit of digital information in computing and telecommunications that consists of eight bits. The term is often used when the term '' byte'' might be ambiguous, as the byte has historically been used for storage units of a variety of sizes. The term ''octad(e)'' for eight bits is no longer common. Definition The international standard IEC 60027-2, chapter 3.8.2, states that a byte is an octet of bits. However, the unit byte has historically been platform-dependent and has represented various storage sizes in the history of computing. Due to the influence of several major computer architectures and product lines, the byte became overwhelmingly associated with eight bits. This meaning of ''byte'' is codified in such standards as ISO/IEC 80000-13. While ''byte'' and ''octet'' are often used synonymously, those working with certain legacy systems are careful to avoid ambiguity. Octets can be represented using number systems of varying bases such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octet (Bruch)
The String Octet in B major, Op. posth., was composed by Max Bruch for four violins, two violas, cello and double bass. Completed in 1920, the year of his death, it is his last work and would not be published until 1996. The work is also known under the name ''Concerto for String Orchestra (Octet)''. Background The octet was written following a period of depression caused by the death of his wife Clara and the general dire state of World War I, defeated Germany. Unsatisfied with an earlier string quintet in B major that was written in the first three months of 1919, Bruch reworked the string quintet into an octet in 1920. Shortly after its completion, his health deteriorated further, and he died on 2 October. Bruch dedicated the octet to his friend Willy Hess (violinist), Willy Hess, a professor at the Royal Manchester College of Music. Hess, who had the autograph scores in his possession, played through the work with his students, and in 1936 ceded the performing rights to Br ...

Byte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Octave (poetry)
Octave has been derived from the Latin word ''octāva'', which means “eighth part.” It is a verse form that contains eight lines, which usually appear in an iambic pentameter. In simple words, it can be any stanza in a poem that has eight lines and follows a rhymed or unrhymed meter.The New Princeton Encyclopedia of Poetry and Poetics.''p. 223 Ed. Alex Preminger and T.V.F. Brogan. Princeton UP, 1993 An octave is a verse form consisting of eight lines of iambic pentameter (in English) or of hendecasyllables (in Italian). The most common rhyme scheme for an octave is ABBA ABBA. An octave is the first part of a Petrarchan sonnet The Petrarchan sonnet, also known as the Italian sonnet, is a sonnet named after the Italian poet Francesco Petrarca, although it was not developed by Petrarch himself, but rather by a string of Renaissance poets.Spiller, Michael R.

Octant (solid Geometry)
An octant in solid geometry is one of the eight divisions of a Euclidean three-dimensional coordinate system defined by the signs of the coordinates. It is analogous to the two-dimensional ''quadrant'' and the one-dimensional ''ray''. The generalization of an octant is called ''orthant'' or ''hyperoctant''. Naming and numbering A convention for naming an octant is to give its list of signs, e.g. (+,−,−) or (−,+,−). Octant (+,+,+) is sometimes referred to as the ''first octant'', although similar ordinal name descriptors are not defined for the other seven octants. The advantages of using the (±,±,±) notation are its unambiguousness, and extensibility for higher dimensions. The following table shows the sign tuples together with likely ways to enumerate them. A binary enumeration with − as 1 can be easily generalized across dimensions. A binary enumeration with + as 1 defines the same order as balanced ternary. The Roman enumeration of the quadrants is in G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octal
Octal (base 8) is a numeral system with eight as the base. In the decimal system, each place is a power of ten. For example: : \mathbf_ = \mathbf \times 10^1 + \mathbf \times 10^0 In the octal system, each place is a power of eight. For example: : \mathbf_8 = \mathbf \times 8^2 + \mathbf \times 8^1 + \mathbf \times 8^0 By performing the calculation above in the familiar decimal system, we see why 112 in octal is equal to 64+8+2=74 in decimal. Octal numerals can be easily converted from binary representations (similar to a quaternary numeral system) by grouping consecutive binary digits into groups of three (starting from the right, for integers). For example, the binary representation for decimal 74 is 1001010. Two zeroes can be added at the left: , corresponding to the octal digits , yielding the octal representation 112. Usage In China The eight bagua or trigrams of the I Ching correspond to octal digits: * 0 = ☷, 1 = ☳, 2 = ☵, 3 = ☱, * 4 = ☶, ...

Lambda Cube
In mathematical logic and type theory, the λ-cube (also written lambda cube) is a framework introduced by Henk Barendregt to investigate the different dimensions in which the calculus of constructions is a generalization of the simply typed λ-calculus. Each dimension of the cube corresponds to a new kind of dependency between terms and types. Here, "dependency" refers to the capacity of a term or type to Free variables and bound variables, bind a term or type. The respective dimensions of the λ-cube correspond to: * x-axis (\rightarrow): types that can depend on terms, corresponding to dependent types. * y-axis (\uparrow): terms that can depend on types, corresponding to Parametric polymorphism, polymorphism. * z-axis (\nearrow): types that can depend on other types, corresponding to (binding) type operators. The different ways to combine these three dimensions yield the 8 vertices of the cube, each corresponding to a different kind of typed system. The λ-cube can be generali ...

Space Frame
In architecture and structural engineering, a space frame or space structure (Three-dimensional space, 3D truss) is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometry, geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing Structural load, loads (bending moment (physics), moments) are transmitted as tension (mechanics), tension and compression (physical), compression loads along the length of each strut. Chief applications include buildings and vehicles. History Alexander Graham Bell from 1898 to 1908 developed space frames based on tetrahedral geometry. Bell's interest was primarily in using them to make rigid frames for nautical and aeronautical engineering, with the tetrahedral kite, tetrahedral truss being one of his inventions.
