An aluminum fence is a fence constructed primarily out of the element aluminium. Due to the metal’s low density and ability to resist corrosion, it has become a popular choice as lightweight, durable fence and railing structure. Aluminum fencing is used for both commercial and residential use.
In optics, Lambert's cosine law says that the observed radiant intensity or luminous intensity from an ideal diffusely reflecting surface or ideal diffuse radiator is directly proportional to the cosine of the angle θ between the observer's line of sight and the surface normal; I = I 0 cos θ.
Glass framing is typically metal (e.g., aluminum) because vinyl will soften and wood will become super dried at the 180 °F (82 °C) temperature that can exist behind the glass in the wall. Heat from sunlight passing through the glass is absorbed by the dark surface, stored in the wall, and conducted slowly inward through the masonry.
Site-specific installation by Dan Flavin, 1996, Menil Collection Interior of Santa Maria Annunciata in Chiesa Rossa. Milan, Italy.. Dan Flavin (April 1, 1933 – November 29, 1996) was an American minimalist artist famous for creating sculptural objects and installations from commercially available fluorescent light fixtures.
Another measure of reflectance, depending only on the outgoing direction, is I/F, where I is the radiance reflected in a given direction and F is the incoming radiance averaged over all directions, in other words, the total flux of radiation hitting the surface per unit area, divided by π. [2]
Chesterton's fence states that reforms should not be made until the reasoning behind the existing state of affairs is understood. Child's law states that the space-charge limited current in a plane-parallel diode varies directly as the three-halves power of the anode voltage and inversely as the square of the distance separating the cathode and ...
