“Oscillating” Metallocene Catalysts: How Do They Oscillate?
Angewandte Chemie International Edition, 2002Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.

Oscillation frequency in CML and ESCL ring oscillators
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2001In this paper a model to accurately evaluate even in a pencil-and-paper manner the oscillation frequency of a ring oscillator made up by a CML or ESCL differential gate is proposed. The model allows us to simply estimate the oscillation frequency changes due both to the bias current change and to process tolerances.

Simultaneous Oscillations in Oscillators
Transactions of the IRE Professional Group on Circuit Theory, 1954An oscillator with two degrees of freedom can, under certain conditions, oscillate simultaneously at two different frequencies. The ratio of the two frequencies may be rational (synchronous oscillations) or irrational (asynchronous oscillations). The conditions necessary for 'simultaneous oscillations are discussed for these two cases.

Oscillations in an Ensemble of Noninteracting Oscillators
1989The two most important cases in application are the almost trivial one in which all the oscillators are identical and the much more interesting one when the parameters of the oscillators are scattered either in frequency or in damping. The consideration of the behavior of an ensemble of identical noninteracting oscillators is the main subject of the ...
