Grate firing is a type of industrial combustion system used for solid fuels. It now is used mainly for burning waste and biomass, but also for smaller coal furnaces. Capacities 0.3 to 175 MWth in industry and CHP; Fuel fired per grate area 1-2 MW/m 2, maximum grate area 100 m 2
The Ice Sheet at Ogden, also known as the Weber County Ice Sheet, is located 35 miles (56 km) north of Salt Lake City on the campus of Weber State University in Ogden. The Ice Sheet opened in 1994 as a recreational training center for curling , ice hockey , and figure skating .
A blazed diffraction grating reflecting only the green portion of the spectrum from a room's fluorescent lighting. For a diffraction grating, the relationship between the grating spacing (i.e., the distance between adjacent grating grooves or slits), the angle of the wave (light) incidence to the grating, and the diffracted wave from the grating is known as the grating equation.
For example, two identical transparent gratings of 50% duty cycle and the same orientation will appear fully opaque only if the relative phase is π (180 degrees). Gratings with sine wave profiles are used extensively in optics to determine the transfer functions of lenses. A lens will form an image of a sine wave grating that is still ...

Gnomonic projection of a portion of the north hemisphere centered on the geographic North Pole The gnomonic projection with Tissot's indicatrix of deformation. A gnomonic projection, also known as a central projection or rectilinear projection, is a perspective projection of a sphere, with center of projection at the sphere's center, onto any plane not passing through the center, most commonly ...
Weber State has an independent, student-run newspaper, The Signpost, that publishes twice weekly. The Signpost publishes the news and events on campus and around Ogden City through digital and print editions. The university also has a student and volunteer-run online radio station, KWCR Wildcat Radio. The station teaches students how to operate ...
