Pattern (other)
A pattern is an original object used to make copies, or a set of repeating objects in a decorative design and in other disciplines. Pattern, patterns, or patterning may also refer to: Mathematics, science, and technology Computing * Software design pattern, a standard form for a solution to common problems in software design. ** Architectural pattern, for software architecture ** Interaction design pattern, used in interaction design / human-computer interaction * Pattern recognition, in machine learning * In machine learning, a non-null finite sequence of constant and variable symbols * Regular expression, often called a pattern Other * Airfield traffic pattern, the traffic flow immediately surrounding a runway * Design pattern, a standard form for a solution to common problems in design **Pattern book, a book of architectural designs ** Pattern (architecture), a standard form (pattern language) for a solution to common problems in architecture ** Software design pattern (see ...

Pattern
A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeated like a wallpaper design. Any of the senses may directly observe patterns. Conversely, abstract patterns in science, mathematics, or language may be observable only by analysis. Direct observation in practice means seeing visual patterns, which are widespread in nature and in art. Visual patterns in nature are often chaotic, rarely exactly repeating, and often involve fractals. Natural patterns include spirals, meanders, waves, foams, tilings, cracks, and those created by symmetries of rotation and reflection. Patterns have an underlying mathematical structure; indeed, mathematics can be seen as the search for regularities, and the output of any function is a mathematical pattern. Similarly in the sciences, theories explain and pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple Patterning
Multiple patterning (or multi-patterning) is a class of technologies for manufacturing integrated circuits (ICs), developed for photolithography to enhance the feature density. It is expected to be necessary for the 10 nm and 7 nm node semiconductor processes and beyond. The premise is that a single lithographic exposure may not be enough to provide sufficient resolution. Hence additional exposures would be needed, or else positioning patterns using etched feature sidewalls (using spacers) would be necessary. Even with single exposure having sufficient resolution, extra masks have been implemented for better patterning quality such as by Intel for line-cutting at its 45nm node or TSMC at its 28nm node. Even for electron-beam lithography, single exposure appears insufficient at ~10 nm half-pitch, hence requiring double patterning. Double patterning lithography was first demonstrated in 1983 by D. C. Flanders and N. N. Efremow. Since then several double patterning te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of "Weird Al" Yankovic Polka Medleys
Polka-style Medley (music), medleys of cover songs are a distinguishing part of American musician, Satire, satirist, parodist, and songwriter "Weird Al" Yankovic's music catalog, catalog. Twelve of his fourteen albums contain them; his "Weird Al" Yankovic (album), self-titled debut and ''Even Worse'' omit them. The medleys are composed of various Popular music, popular songs, each one reinterpreted as a polka (generally an instrumentation (music), instrumentation of accordion, banjo, tuba, clarinet, and Mute (music), muted brass instrument, brass interspersed with sound effects) with the choruses or memorable lines of various songs juxtaposed for humorous effect and profane lyrics are covered with cartoon sound effects. Yankovic has been known to say that converting these songs to polka was "...the way God intended". Yankovic said that the medleys were something he did "even before I had a record deal" in live performances, and that many of the songs are included due to not receivin ...
