The one component that may be hard to find is the parabolic reflector. You cannot simply use a bowl or other curved object as the precise parabolic shape ensures that sound waves are reflected ...

Parabolic reflectors for solar applications are nice stuff, and making your own is a great project in itself. One of the easiest ways we have seen is that of [GREENPOWERSCIENCE], who uses nothing ...

This focussing effect is very strong with wavelengths less than the aperture of the reflector, making it particularly suitable for recording high frequency sounds such as birdsong. Schematic diagram ...

It will be readily understood that this trough with its bent ribs and flat minors forms a perfect parabolic reflector, to which a cylindrical heater, as stated, may be attached for generating ...

Some of the reflector segments are covered to prevent powerful rays ... The solar array assembly features a 430.5-square foot parabolic dish coated with 36 plastic foil elliptic mirrors that are just ...

We’ll call them semi smart. The new bulbs will be available in A19, BR (bulged reflector), and PAR (parabolic aluminized ...

Researchers at Osaka Metropolitan University have developed a straightforward method for predicting the measurement precision of fringe projection photogrammetry.
