چکیده
The dynamics of cables with concentrated loads is studied using a direct perturbation method (DPM) combined with multiple time scales. A general cable model is assumed to have complex loads, including nonlinear aerodynamic force and concentrated masses. An early developed perturbation method––DPM–– is applied to investigate the cable s motion. This approach does not need to transform the original partial differential equations to ordinary differential equations, and the solution procedure is systematic. Static profile is found and the frequency equation is explicitly derived using linear analysis. The direct perturbation approach is employed to find nonlinear solutions, and governing equations are obtained which can be used to determine the stabilities of the steady-state solutions. 2003 Elsevier Science B.V.

A procedure, we call it generalized competitive mode (GCM), is proposed to estimate the parameter regimes of chaos in nonlinear systems by implementing a mathematical version of mode competition. The idea is that for a system to be chaotic there must exist at least two GCMs in the system. The Lorenz system and a thin plate in flow-induced vibrations system are analyzed to find chaotic regimes b...

In a previous paper [Chaos Solitons Fract. 14(2) (2002) 173], the authors investigated the dynamics of the equation: dx dt2 þ ðd þ cos tÞxþ Ax " þ Bx dx dt þ Cx dx dt 2 þ D dx dt 3# 1⁄4 0 We used the method of averaging in the neighborhood of the 2:1 resonance in the limit of small forcing and small nonlinearity. We found that a degenerate bifurcation point occurs in the resulting slow flow and...

This paper is concerned with the effect of time delayed feedbacks in a nonlinear oscillator with external forcing. The particular attention is focused on the case that the corresponding linear system has two pairs of purely imaginary eigenvalues at a critical point, giving rise to double Hopf bifurcations. An analytical approach is used to find the explicit expressions for the critical values o...
متن کاملPartial redundancy elimination: a simple, pragmatic, and provably correct algorithm
We propose a new algorithm for partial redundancy elimination based on the new concepts of safe partial availability and safe partial anticipability. These new concepts are derived by the integration of the notion of safety into the de3nitions of partial availability and partial anticipability. The algorithm works on 5ow graphs whose nodes are basic blocks. It is both computationally and lifeti...
