And Tables 1, 2, and 3 show the antinoise
ability of the above three algorithms for two tested images, respectively.
Figure 6 demonstrates that when there exists noise, adaptive Fourier filter obtains better antinoise
ability than conventional Kalman filter.
HUNDREDS of antinoise
protesters marched on Downing Street yesterday in a demonstration against the decision to give the goahead to a fifth terminal at Heathrow Airport.
enclosures and central dust extraction (2 x 10" pipes) recommended Torwegge H 604 Series 18,000-26,000 lbs.
The other, Jesus Pica Planas, is representative of most of these men, for creating a number of devices "striking in their uselessness," including an antinoise
device for enamored cats and a mousetrap in the form of a guillotine.
The new technology will also allow automakers to make lighter vehicles as they will not need to add antinoise
materials to chassis, they said.
104, 119 (1972) (upholding antinoise
ordinance governing area around public schools because law "is narrowly tailored to further [city's] compelling interest in having an undisrupted school session conducive to the student's learning, and does not unnecessarily interfere with First Amendment rights.")
circuitry can squelch sound at frequencies below roughly 1,200 hertz, reducing the noise to as little as one-eighth of its untreated loudness, says Michael A.
" only works on repeating low frequency noises (below 1500 Hz).
PUT A MUZZLE ON IT...An antinoise
generator, a device designed to reduce the sound of buses, is being tested in New York, Houston and two transit systems in Southern California.
Engineers are now designing equipment that uses antinoise
to silence loud machinery.
The Noise Cancellation Technologies exhaust muffler employs a feedback control design to generate an antinoise
signal at the end of an automobile exhaust pipe.
