The stability of pulse-widtli-modulated control systems has been an active area of research since the early 1960's.
Resource sharing systems, such as database management systems, utilize various types of locking to maintain consistency.
The preceding paper1 has considered the theory of active transmission lines with discrete imperfections.
We have investigated the sqrt (3X) sqrt 3 surface structure of B/Si(111) using in-plane and out-of-plane x-ray data.
AT&T Bell Laboratories has shown that high quality X-Ray mask membranes can be fabricated from hydrogen-doped boron nitride films deposited upon silicon substrates by a low pressure CVD process
We have undertaken a new set of experiments to investigate the behavior of adsorbed-impurity induced reconstructions at growth interfaces.
Stability of Distributed Systems With Feedback via Michailov's Criterion By G. C.
Membrane mirrors with transparent electrodes were fabricated for adaptive optics. These devices are capable of large, low order deformations but exhibit instability for high order deformations.
Membrane mirrors with transparent electrodes were fabricated for adaptive optics.
The frequency feedback (or frequency compression) demodulator for FM signals was proposed by J. G. Chaffee 1 in 1937.
