چکیده
Dynamics of a Local Perturbation in the XY Mode!. I-Approach to Equilibrium D. B. Abraham§, E. Barouch∗§, G. Gallavotti and A. Martin-Löf Abstract: The magnetization and spin correlation functions of theX−Y model are analysed exactly when the system is subjected to a local perturbation of the magnetic field in the z-direction. When such a perturbation is removed, these quantities approach their equilibrium values asymptotically as (time)→ ∞

A study on the use of perturbation technique for analyzing the nonlinear forced response of piezoelectric microcantilevers
In this paper, a comparison is made between direct and indirect perturbation approaches to solve the non-linear vibration equations of a piezoelectrically actuated cantilever microbeam. In this comparison, the equation of motion is considered according to Euler-Bernoulli theory with considering the non-linear geometric and inertia terms resulted from shortening effect. In the direct perturbatio...
متن کاملEstimation of the Domain of Attraction of Free Tumor Equilibrium Point for Perturbed Tumor Immunotherapy Model
In this paper, we are going to estimate the domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model describing the tumor-immune system competition dynamics. The proposed method is based on an optimization problem solution for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We...
متن کاملDynamics of Housing Prices and Economic Fluctuations in Iran with the Approach of Dynamic Stochastic General Equilibrium (DSGE)
This paper studies the relationship between housing prices and business cycles in Iran. Since housing has a dual nature, that is, both private and capital nature, it can play an important role in investment costs and economic growth and incite other manufacturing sectors in the country. In this paper, housing prices and business cycles have been used to measure housing as a collateral, which is...
متن کاملIntelligent identification of vehicle’s dynamics based on local model network
This paper proposes an intelligent approach for dynamic identification of the vehicles. The proposed approach is based on the data-driven identification and uses a high-performance local model network (LMN) for estimation of the vehicle’s longitudinal velocity, lateral acceleration and yaw rate. The proposed LMN requires no pre-defined standard vehicle model and uses measurement data to identif...
متن کاملMulti-frequency piezomagnetoelastic energy harvesting in the monostable mode
The present article investigates effects of the multi-frequency excitation on the output power of a piezomagnetoelastic energy harvester. The piezomagnetoelastic power generator is assumed to operate in the mono-stable mode. A perturbation technique based on the method of multiple scales is employed to develop an analytical solution to nonlinear differential equations governing the system dynam...
