Stabilizing the low frequencies
The Leading Edge, 2007Acoustic and elastic impedance sections have two main uses. Firstly, they “look more like geology” than traditional reflectivity data, and enable us to better communicate the subsurface images to our non-geoscientist colleagues (e.g., reservoir engineers and drillers).

IEEE Transactions on Power Systems, 2018
This paper investigates how the operation of the onshore AC grid and the offshore voltage source converter-based multiterminal dc (VSC-MTDC) grid can be cooptimized within the unit commitment (UC) framework to enhance system frequency stability following

A Stabilized Frequency Divider
Proceedings of the IRE, 1941A method is described for stabilizing the frequency of a relaxation oscillator to any required degree. The stabilized oscillator may be synchronized with a high-order submultiple of a control frequency without any possibility of synchronization at any other submultiple, even if the operating conditions vary widely; the maintenance of synchronization ...

Frequency stabilized diode lasers
AIP Conference Proceedings, 1991Frequency stabilized semiconductor lasers have many applications in spectroscopy, metrology and coherent communication systems. The last trends and results on frequency stabilization of laser diodes are presented in the report.Three laser systems are considered: a solitary laser diode, a diode with integrated composite cavity, and a semiconductor laser

Frequency stability and measurement
1993An ideal source provides a single spectral line with zero width and finite energy. This strange mathematical world does not exist in practice, because real oscillators produce lines of finite width and have random amplitude, frequency and phase fluctuations.
