Abstract: This paper presents a method for analyzing a pair of coupled nonlinear differential equations of the Duffing type in order to determine whether linearly related modal oscillations of the system ...

Abstract: The rapid development of integrated circuit technology from small-scale integration (SSI) to very large scale integration (VLSI) has had great technological and economical impact on the electronics ...

Abstract: This paper attempts to identify the principal parameters that influence the behavior of drilling and production risers and to explain how and why they do so. Clear understanding of these ...

Abstract: In this work, Galerkin approximations are developed for a system of n first order nonlinear delay differential equations (DDEs) and also for an nth order nonlinear scalar DDE. The DDEs are ...

Abstract: The derivation and application of the Lagrange equations of motion to systems with mass varying explicitly with position are discussed. Two perspectives can be followed: systems with a material ...

Abstract: For valve closure transients in pipelines, friction attenuates the amplitude of water hammer wave fronts and causes line packing. The latter is a sustained head increase behind the wave front. Line packing can lead to ...
