Stability of Oscillations of Superposed Fluids
Journal of Applied Physics, 1956The Stokes-Taylor instability of the interface of two superposed fluids is studied. The two uniform layers of heavy fluids are of different densities and viscosities and are incompressible. Surface tension and gravity are taken into consideration. The main problem considered is the role of viscosity on the modes of decay and growth of waves, and the ...

Combustion Stabilization by Forced Oscillations in a Duct
SIAM Journal on Applied Mathematics, 2005The author develops a model and mathematical technique in order to simulate an active control input-output mechanism. The developed model describes the interaction of an existing oscillation in the combustor with a control input and with a flame. Such a model and mathematical technique significantly differ from that used by previous authors for single ...

1970 International Electron Devices Meeting, 1970
The purpose of the present paper is to show experimentally the effect of circuit parameters and environmental conditions on the performance characteristics of a Gunn oscillator, especially electronic tuning, noise, and stability. The temperature is the most serious factor limiting the stability of the oscillator.

Relaxation oscillations and stability
IEEE Journal of Quantum Electronics, 1982The phenomenon of relaxation oscillations is reexamined from the viewpoint of stability theory. We show that undamped relaxation oscillations with modulation depths of unity can be understood as centers at zero photon density. In addition, we show that the threshold pump rate and the criteria for eliminating relaxation oscillations can be obtained from

Prominence Oscillations and Stability
International Astronomical Union Colloquium, 1994AbstractA number of high-amplitude prominence oscillations of different modes, triggered by various perturbations, are presented and classified as membrane-like, string-like, sausage-like and elastic-spring-like oscillations.

On the stabilization of betatron oscillations
Il Nuovo Cimento A, 1967The stabilization of electron oscillation amplitudes at constant energy in synchrotron has been investigated experimentally and theoretically. It has been shown that one can obtain satisfactory agreement between the experimental results and theory only taking into account the fact that the electron energy levels in the oscillator potential-well are ...

Microwave oscillator stability
Transactions of the IRE Professional Group on Electron Devices, 1954By considering an oscillator as a regenerative noise amplifier, one can define an output half-power noise bandwidth. This quantity, which can be calculated from the physical constants of the oscillator, is an exact measure of the purity of the oscillator output. A small noise bandwidth indicates a relatively constant output frequency. Calculations show

A stabilized transistor oscillator
1955 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1955Summary form only given. The most serious causes of frequency instability are the effect of temperature on parameters of transistors and the variation of supply voltage. There are some circuit arrangements which can considerably minimize these effects.
