... technique is used for stability analysis of periodic orbit. The evolution of bifurcation point is predicted by the calculating the Floquet multipliers of monodromy matrix, and it is known to achieve the same objective as the Poincare map technique in much more straightforward way.

A symmetric correction is proposed...

... is stabilized by the gravitational force. The aim of the design is the achievement of a given magnetic force pattern on the upper chain elements in the most displaced positions allowed by the gaps, as follows. In order to prevent wear abrasion the radial force on each chain element must be outward directed...

... is developed based on a second order formula used for numerical integration of differential equations. Stability of the newly obtained transfer functions in the z-domain is proved to be preserved. Distortions introduced by the new transform into the original amplitude and group delay responses are studied...

.... We prove here that for α > 4, the scheme is instable. For α > 4, we have (see equation 29) Suppose that: (see equation 30) (see equation 31) which is not valid since α > 4 and, therefore, the scheme is instable. We deduce from this study the following stability condition: (see equation...

... problem concerning this class of circuits is the stability of the equilibrium states (Chua, 1978, 1980; Chua and Green, 1976; Green and Willson, 1992, 1994; Tadeusiewicz, 1997). To obtain the equilibrium states (equilibrium points) of a dynamic circuit we short‐circuit all the inductors and open‐circuit...
