The first versions of SMARTS were developed by Dr. Gueymard while he was at the Florida Solar Energy Center. [2] [3] [4] The model employed a structure similar to the earlier SPCTRAL2 model, still offered by the National Renewable Energy Laboratory (), but with finer spectral resolution, as well as updated extraterrestrial spectrum and transmittance functions.
Tissot introduced its first tactile watch, with "T-Touch," technology in 1999; watches containing this technology have touch-sensitive sapphire crystals to control various functions including compass, barometer, altimeter and thermometer. The 2014 T-Touch Expert Solar and T-Touch Lady Solar had 25 functions. [14]
Tissot, a Swiss luxury watchmaker, makes the Silen-T wristwatch with a touch-sensitive face that vibrates to help the user to tell time eyes-free. The bezel of the watch features raised bumps at each hour mark; after briefly touching the face of the watch, the wearer runs a finger around the bezel clockwise.
It was powered by a computer on a chip, and was compatible with most of the popular PCs of that time, including Apple II, II+ and IIe, BBC Micro, [10] Commodore 64, [11] IBM PC, NEC 8201, Tandy Color Computer, Model 1000, 1200, 2000 and TRS-80 Model I, III, 4 and 4p. The RC-20 Wrist Computer was released in 1985, [12] [13] followed by the RC ...
A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. Attempts to create such a model established the more general field of celestial mechanics. The results of this simulation can be compared with past measurements to check for accuracy ...
The invention, which is similar to Corning's widely used Gorilla Glass, could be used in the development of flexible computer displays and ultra-thin smartphones. [138] The solar-powered Solar Impulse aircraft lands in Morocco after a 19-hour flight from Spain, marking the first intercontinental flight of a purely solar-powered aircraft. [139]
The Parker Solar Probe (PSP; previously Solar Probe, Solar Probe Plus or Solar Probe+) [6] is a NASA space probe launched in 2018 to make observations of the Sun's outer corona. It used repeated gravity assists from Venus to develop an eccentric orbit, approaching within 9.86 solar radii (6.9 million km or 4.3 million miles) [ 7 ] [ 8 ] from ...
The Behrmann projection with Tissot's indicatrices The Mercator projection with Tissot's indicatrices. In cartography, a Tissot's indicatrix (Tissot indicatrix, Tissot's ellipse, Tissot ellipse, ellipse of distortion) (plural: "Tissot's indicatrices") is a mathematical contrivance presented by French mathematician Nicolas Auguste Tissot in 1859 and 1871 in order to characterize local ...
