 picture info Portmanteau A portmanteau (, /ˌpɔːrtmænˈtoʊ/) or portmanteau word (from English "portmanteau", a kind of luggage; in French: mot-valise) is a blend of words[1] in which parts of multiple words are combined into a new word,[1][2][3] as in smog, coined by blending smoke and fog,[2][4] or motel, from motor and hotel.[5] In linguistics, a portmanteau is a single morph that is analyzed as representing two (or more) underlying morphemes.[6][7][8][9] A portmanteau word is similar to a contraction, but contractions are formed from words that would otherwise appear together in sequence, such as do and not to make don't, whereas a portmanteau is formed by combining two or more existing words that all relate to a single concept [...More Info...]       [...Related Items...] picture info Palo Alto, California Palo Alto (/ˌpæloʊ ˈæltoʊ/) is a charter city located in the northwestern corner of Santa Clara County, California, United States, in the San Francisco Bay Area. Palo Alto means tall stick in Spanish; the city is named after a coastal redwood tree called El Palo Alto. The city was established by Leland Stanford Sr. when he founded Stanford University, following the death of his son, Leland Stanford Jr. Palo Alto includes portions of Stanford University and shares its borders with East Palo Alto, Mountain View, Los Altos, Los Altos Hills, Stanford, Portola Valley, and Menlo Park [...More Info...]       [...Related Items...] picture info Space Probe A space probe or a spaceprobe is a robotic spacecraft that does not orbit around the Earth, but instead, explores further into outer space.[2] A spaceprobe may approach the Moon; travel through interplanetary space; flyby, orbit, or land on other planetary bodies; or enter interstellar space. The space agencies of the USSR (now Russia and Ukraine), the United States, the European Union, Japan, China, India, and Israel have collectively launched probes to several planets and moons of the Solar System, as well as to a number of asteroids and comets [...More Info...]       [...Related Items...] picture info Jet Propulsion Laboratory The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in the city of La Cañada Flintridge, with a Pasadena mailing address,[1] in California, United States. Founded in the 1930s, JPL is currently owned by NASA and managed by the nearby California Institute of Technology (Caltech) for NASA.[2] The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions [...More Info...]       [...Related Items...] picture info IBM Personal Computer The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first computer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by Don Estridge in Boca Raton, Florida. The machine was based on open architecture and a substantial market of third-party peripherals, expansion cards and software grew up rapidly to support it. The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world, and the only significant competition it faced from a non-compatible platform throughout the 1980s was from the Apple Macintosh product line [...More Info...]       [...Related Items...] Regular Grid A regular grid is a tessellation of n-dimensional Euclidean space by congruent parallelotopes (e.g. bricks).[1] Grids of this type appear on graph paper and may be used in finite element analysis, finite volume methods, finite difference methods, and in general for discretization of parameter spaces. Since the derivatives of field variables can be conveniently expressed as finite differences,[2] structured grids mainly appear in finite difference methods [...More Info...]       [...Related Items...] picture info Convolution Kernel In mathematics (in particular, functional analysis), convolution is a mathematical operation on two functions (f and g) that produces a third function (${\displaystyle f*g}$) that expresses how the shape of one is modified by the other. The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two functions after one is reversed and shifted [...More Info...]       [...Related Items...] Intensity (physics) In physics, intensity of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m2). It is used most frequently with waves such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used. Intensity can be applied to other circumstances where energy is transferred. For example, one could calculate the intensity of the kinetic energy carried by drops of water from a garden sprinkler. The word "intensity" as used here is not synonymous with "strength", "amplitude", "magnitude", or "level", as it sometimes is in colloquial speech [...More Info...]       [...Related Items...]
