The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface. It cannot be simply related to the irradiance (measured in W / m 2 ) because the UV of greatest concern occupies a spectrum of wavelengths from 295 to 325 nm, and shorter wavelengths have already been absorbed a ...
UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...
But on Jan. 13, 1985, 40 years ago today, one of Texas' largest cities was digging out from an historic snowstorm. ... San Antonio picked up 13.5 inches of snow, most of which fell in 24 hours ...
The Planckian locus on the MacAdam (u, v) chromaticity diagram. The normals are lines of equal correlated color temperature. The CIE 1960 color space ("CIE 1960 UCS", variously expanded Uniform Color Space, Uniform Color Scale, Uniform Chromaticity Scale, Uniform Chromaticity Space) is another name for the (u, v) chromaticity space devised by David MacAdam.
Houston winters are, on average, colder than South Florida and Southern California, on par with southern Louisiana and Central Florida, but slightly warmer than Dallas, Atlanta, San Antonio, Austin, and other inland southern cities. The average high in January, the coldest month, is 62.9 °F (17.2 °C) and the low 43.2 °F (6.2 °C).
UV swimwear. Sun protective clothing is clothing specifically designed for sun protection and is produced from a fabric rated for its level of ultraviolet (UV) protection. A novel weave structure and denier (related to thread count per inch) may produce sun protective properties. In addition, some textiles and fabrics employed in the use of sun ...
Greater Houston is part of the Texas Triangle megaregion along with the Dallas–Fort Worth metroplex, Greater Austin, and Greater San Antonio. Greater Houston also serves as a major anchor and economic hub for the Gulf Coast. Its Port of Houston is the largest port in the United States and the 16th-largest in the world. [12]
The moonlight towers in Austin, Texas, are the only known surviving moonlight towers in the world. They are 165 feet (50 m) tall and have a 15-foot (4.6 m) foundation. A single tower casts light from six carbon arc lamps, illuminating a 1,500-foot-radius (460 m) circle brightly enough to read a watch.
