PARAMETRIC EXCITATION IN A SELF-EXCITED THREE-DEGREES OF FREEDOM PROBLEM

The Response of Two-Degree of Freedom Self-Sustained Systems with Quadratic Nonlinearities to a Parametric Excitation (RESEARCH NOTE)

In this study the interaction between self-excited and paramet rically excited oscillations in two-degree-of-freedom systems with quadratic nonlinearities is investigated. The fundamental parametric resonance of the first mode and 3:1 internal resonance is considered, followed by 1:2 internal and parametric resonances of the second mode. The method of multiple time scales is applied to derive f...

Molecular Docking: A Problem with Thousands of Degrees of Freedom

This paper reports on the problem of docking a highly flexible small molecule to the pocket of a highly flexible receptor macromolecule. The prediction of the intermolecular complex is of vital importance for the development of new therapeutics as docking can alter the chemical behavior of the receptor macromolecule. We first present current methods for docking which however have several limita...

Title of Dissertation: A THREE DEGREE OF FREEDOM PARALLEL MANIPULATOR WITH ONLY TRANSLATIONAL DEGREES OF FREEDOM

Title of Dissertation: A THREE DEGREE OF FREEDOM PARALLEL MANIPULATOR WITH ONLY TRANSLATIONAL DEGREES OF FREEDOM Richard Eugene Stamper, Doctor of Philosophy, 1997 Dissertation directed by: Professor Lung-Wen Tsai Department of Mechanical Engineering and Institute for Systems Research In this dissertation, a novel parallel manipulator is investigated. The manipulator has three degrees of freedo...

Synchronization of Self-oscillations by Parametric Excitation

This paper is devoted to the problem of synchronization of symmetrically coupled self-oscillators exhibiting chaos by means of chaos control technique. We use a nonfeedback method of control, in particular, high frequency periodic modulation of the coefficient of coupling. The model of Chua’s circuits coupled via capacity is considered in this work. We study the possibility of synchronization i...
