A higher-order sandwich theory is implemented in conjunction with an equivalent mobility-based power flow progressive method to determine power flow for a sandwich configured floating raft vibration isolation system. The power spectrum changes in whole frequency range effectively when core materials’ properties change. It is also shown that the loss factors of the sandwich configured floating r...

This paper aims at testing and modeling business-cycle asymmetries within a structural time-series framework, allowing for smooth transition in the parameters characterizing the cyclical component, namely, the damping factor and the frequency. An LM test of linearity is derived, and illustrations are provided with reference to a set of quarterly U.S. industrial production series for two-digit m...

A closed form solution for characterizing voltage-based signals in an RLC tree is presented. This closed form solution is used to derive figures of merit to characterize the effects of inductance at a specific node in an RLC tree. The effective damping factor of the signal at a specific node in an RLC tree is shown to be a useful figure of merit. As the effective damping factor of a signal incr...

Our concern in the present work is a Timoshenko laminated beam system with nonlinear delay and structural damping acting equation describing dynamics of slip. The aim to establish an explicit general energy decay rates solution under suitable assumptions on weight speeds wave propagation. To achieve our desired stability results, we exploit some properties convex functions, coupled multiplier t...

in this paper, a novel compensator based on magnetically controlled reactor with fixed capacitor banks (fc-mcr) is introduced and then power system stability in presence of this compensator is studied using an intelligent control method. the problem of robust fc-mcr-based damping controller design is formulated as a multi-objective optimization problem. the multi-objective problem is concocted ...

The Gilbert damping of ferromagnetic materials is arguably the most important but least understood phenomenological parameter that dictates real-time magnetization dynamics. Understanding the physical origin of the Gilbert damping is highly relevant to developing future fast switching spintronics devices such as magnetic sensors and magnetic random access memory. Here, we report an experimental...

We consider the damping problem for a nonstationary control system described by of differential-difference equations neutral type with smooth matrix coe cients and several delays. This is equivalent to boundary-value second-order differentialdifference equations, which has unique generalized solution. It proved that smoothness this solution can be violated on considered interval preserved only ...

Abstract We investigate the validity of quantum regression for a family Hamiltonians on multipartite system leading to phase-damping reduced dynamics. After finding necessary and sufficient conditions CP-divisibility corresponding channel, we evaluate hierarchy equations equivalent under arbitrary interventions; in particular, find nontrivial dephasing be compatible with regression. In this fra...
