The All in the Family story makes one wonder how many other gems never had the chance to become classics. The good news, however, is that there are plenty of shows that have stood the test of time.

Gaussian filters are used in image processing because they have a property that their support in the time domain, is equal to their support in the frequency domain. This comes about from the Gaussian being its own Fourier Transform.
The Ovivo Â® Stone Trap TM system removes small stones and rocks from screenings when water is used for screenings transport. If not removed, stones and rocks will result in premature wear of the screw mechanism used in screenings compaction and dewatering. Since water is used to transport screenings in many applications, such as with Ovivo's center flow and drum screens, the Stone Trap is an ideal pre-screening method.
