The earliest examples of color codes in use are for long-distance communication by use of flags, as in semaphore communication. [1] The United Kingdom adopted a color code scheme for such communication wherein red signified danger and white signified safety, with other colors having similar assignments of meaning.
This example shows an image with a portion greatly enlarged so that individual pixels, rendered as small squares, can easily be seen. In digital imaging, a pixel (abbreviated px), pel, [1] or picture element [2] is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device.
His voice was an omnipresent cry in our electronic world. His sharp features, majestic looks, and prancing style a vivid etching on the landscape of our minds. Bob Marley was never seen. He was an experience which left an indelible imprint with each encounter. Such a man cannot be erased from the mind.
FOV both eyes Vertical FOV Angle of view can be measured horizontally, vertically, or diagonally. A 360-degree panorama of the Milky Way at the Very Large Telescope.In the image, the Milky Way appears like an arc of stars spanning horizon to horizon with two streams of stars seemingly cascading down like waterfalls.
Micrograph of a polycrystalline metal; grain boundaries evidenced by acid etching. Differently-oriented crystallites in a polycrystalline material. In materials science, a grain boundary is the interface between two grains, or crystallites, in a polycrystalline material.
Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures 4.9 by 2.8 by 0.9 inches ...
Refraction of light at the interface between two media of different refractive indices, with n 2 > n 1.Since the velocity is lower in the second medium (v 2 < v 1), the angle of refraction θ 2 is less than the angle of incidence θ 1; that is, the ray in the higher-index medium is closer to the normal.
In mathematics, a conformal map is a function that locally preserves angles, but not necessarily lengths.. More formally, let and be open subsets of .A function : is called conformal (or angle-preserving) at a point if it preserves angles between directed curves through , as well as preserving orientation.
