Spintronics (also known as magnetoelectronics) is an emerging technology which exploits the intrinsic spin of electrons and its associated magnetic moments, in addition to its fundamental electronic charges. Utilization of the electron’s spins has advantages such as low power consumption, and non-volatility over the conventional electronic devices. Magnetization dynamics in magnetic nanoscale devices has been intensively studied recently due to its potential in memories and logic devices. Two aspects of magnetization dynamics have been investigated in this book such as magnetic domain walls (particle-like objects) and spin waves (wave-like objects). The effect of current-induced spin transfer torque on the magnetization dynamics in which spin angular momentum from conduction electrons transfers to local magnetic moments has been explored. The main purpose of this study is in the utilization of the magnetization dynamics for device applications and each chapter of the book explores various characteristics of the magnetization dynamics.

Price Dynamics in Equilibrium Models - The Search for Equilibrium and the Emergence of Endogenous Fluctuations

13503 руб.
A long-standing unsolved problem in economic theory is how economic equilibria are attained. Price Dynamics in Equilibrium Models: The Search for Equilibrium and the Emergence of Endogenous Fluctuations considers a number of adjustment processes in different economic models and investigates their dynamical behaviour. Two important themes arising in this context are "bounded rationality" and "nonlinear dynamics". Important sub-themes of the book are the following: how do boundedly rational agents interact with their environment and does this interaction in some sense lead to rational outcomes (which may or may not correspond to equilibria)? The second sub-theme deals with the consequences of the nonlinear dynamical nature of many adjustment processes. The results presented in this volume indicate that endogenous fluctuations are the rule rather than the exception in the search for equilibrium. The book uses the theory of nonlinear dynamics to analyze the dynamics of the different economic models. Due to the complexity of most of the models, an important role is played by computational methods. In particular, at regular instances the models are analyzed by numerical simulations and some computer-assisted proofs are provided. It also covers a wide range of dynamical models from economic theory. Most of these models merge the theory of nonlinear economic dynamics with the theory of bounded rationality. The book is written for anyone with an interest in economic theory in general and bounded rationality and endogenous fluctuations in particular. It is entirely self-contained and accessible to readers with only a limited knowledge of economic theory.

The first part of this book is focused on the design of a compass robot as a nonlinear dynamics system. Three components including robot’s structure, gear and motor are interacting during design process to achieve better performance, higher stability and lower cost. After achieving the design method, different actuators are selected for a given structure and the their performance are compared in the terms of cost, efficiency and their effect on the performance. In the second part of the book, the optimization of a nonlinear system with subject to the stability constraint is investigated. Including stability analysis in the optimization process, makes it very complicated and inefficient. Limit cycle convergence is the best solution among the existing methods. In this book, an important step is taken to upgrade the optimization. A computational algorithm is developed which obtains the convergent limit cycle in a short time. This algorithm speeds up the optimization time tremendously and allows the optimization search in a broader area. Even tough a compass robot is considered as an example of the nonlinear system, this algorithm is applicable to all nonlinear dynamics systems.

This book is concerned with the study of nonlinear water waves, which is one of the important observable phenomena in Nature. This study is related to the fluid dynamics, in general, and to the oceans dynamics in particular. The solutions of nonlinear PDEs with constant and variable coefficients, which describe the wave motion of undulant bores in shallow water, are investigated by using various analytical methods to illustrate the relation between solitary and water waves. The important ideas and results for nonlinear dispersive properties and solitons, which originated from the investigations of water waves, are discussed. The stability analysis for the second order system of PDEs is studied by using the phase plane method. In addition, we use perturbation methods to study the water wave problems for an incompressible fluid under the acceleration gravity and surface tension. The conservation laws of some PDEs are established. We illustrate the resulting solutions in several 3D-graphics showing the shock and solitary wave nature in the flow. This book contains many concepts of water wave motion and different mathematical methods that help researchers in the relevant topics.

In this Book, a new measured based friction model is developed to describe the vehicle lateral dynamics which are modeled by a so called two-track vehicle model. The effects of load transfer and the effects caused by slip angles in relation to the track width of the vehicle can be included in this model. On the other hand, the two- track vehicle model incorporates a more sophisticated tire model in order to accurately represent the tire forces and study the vehicle behavior in the nonlinear region. Simulation and experimental results show that, within a considerable range of slip angle, there is a good agreement between the simplified two-track vehicle model and the simulated test data from CarSim. A nonlinear observer for estimation of lateral velocity and yaw rate of automotive vehicles is proposed. This observer is based on yaw rate measurement in addition to steering angle, longitudinal velocity and longitudinal forces measurements. Stability of the proposed observer is investigated with Lyapunov direct method. Simulation results are presented to validate the nonlinear observer, the friction model and to explore automobile behavior in different scenarios.

Nonlinear problems are of interest to engineers, physicists and mathematicians and many other scientists because most systems are inherently nonlinear in nature. As nonlinear equations are difficult to solve, nonlinear systems are commonly approximated by linear equations. This works well up to some accuracy and some range for the input values, but some interesting phenomena such as chaos and singularities are hidden by linearization and perturbation analysis. It follows that some aspects of the behavior of a nonlinear system appear commonly to be chaotic, unpredictable or counterintuitive. Although such a chaotic behavior may resemble a random behavior, it is absolutely deterministic. Analytical Routes to Chaos in Nonlinear Engineering discusses analytical solutions of periodic motions to chaos or quasi-periodic motions in nonlinear dynamical systems in engineering and considers engineering applications, design, and control. It systematically discusses complex nonlinear phenomena in engineering nonlinear systems, including the periodically forced Duffing oscillator, nonlinear self-excited systems, nonlinear parametric systems and nonlinear rotor systems.

The physical essence of complex structures goes beyond Newton's dynamical laws. In this book systems are investigated which exhibit excitable, oscillatory and bistable behavior as basic modes of nonlinear dynamics. Addition of stochastic fluctuations contribute to the appearance of complex behavior. Bifurcations of local behavior as well as nucleation of spatially extended structures are studied. Typical fronts and spirals appear but also unusual patterns such as moving clusters and inverted waves. Methods are presented to find expressions for front velocities in the presence of system boundaries. An abstract two-state model with two waiting time distributions is considered representing excitable dynamics. Instantaneous and delayed response of the ensemble's response is analyzed. Furthermore transport and diffusion of Brownian particles in a spatio-temporal oscillating potential is discussed. As a cause of nearly dispersion-less transport synchronization mechanisms can be identified.

Nonlinear Optimal Model Following Control of Flexible Aircraft

Every aircraft is a flexible body and its motion should be evaluated by the continuum mechanics. However, in the flight mechanics, they are commonly treated as rigid. In other way, in the structural dynamics scenario, rigid body modes are usually neglected. Such segregation is acceptable when sufficient separation exist between the frequencies of rigid and flexible modes. But, trends in the aircraft industry are leading to longer fuselages, larger aspect ratios, smaller thicknesses and the use of composite materials. Such configurations are more flexible and integrated models for flight mechanics and structural dynamics should be taken. This book develops the theme in a scenario of modelling, simulation and optimal control. Models of conceptual flexible aircraft are built in order to be used in control studies. A nonlinear optimal model following control is proposed. Linear solutions are developed, nonlinear approaches are also investigated, via neural networks. The technique is used to approximate the flexible aircraft as a rigid body, letting the job of controlling flexible modes to the automatic control, while an human or autopilot can see the aircraft as a usual rigid body.

The capability to predict the nonlinear response of beams, plates and shells when subjected to thermal and mechanical loads is of prime interest to structural analysis. In fact, many structures are subjected to high load levels that may result in nonlinear load-deflection relationships due to large deformations. One of the important problems deserving special attention is the study of their nonlinear response to large deflection, postbuckling and nonlinear vibration. A two-step perturbation method is firstly proposed by Shen and Zhang (1988) for postbuckling analysis of isotropic plates. This approach gives parametrical analytical expressions of the variables in the postbuckling range and has been generalized to other plate postbuckling situations. This approach is then successfully used in solving many nonlinear bending, postbuckling, and nonlinear vibration problems of composite laminated plates and shells, in particular for some difficult tasks, for example, shear deformable plates with four free edges resting on elastic foundations, contact postbuckling of laminated plates and shells, nonlinear vibration of anisotropic cylindrical shells. This approach may be found its more extensive applications in nonlinear analysis of nano-scale structures. Concentrates on three types of nonlinear analyses: vibration, bending and postbuckling Presents not only the theoretical aspect of the techniques, but also engineering applications of the method A Two-Step Perturbation Method in Nonlinear Analysis of Beams, Plates and Shells is an original and unique technique devoted entirely to solve geometrically nonlinear problems of beams, plates and shells. It is ideal for academics, researchers and postgraduates in mechanical engineering, civil engineering and aeronautical engineering.

Multibody spacecraft are used in a wide range of applications in near-Earth space, from manned space stations to unmanned space telescopes. Such systems cannot be modeled as point mass particles. Their dynamics are quite complex, being characterized by linear and nonlinear coupling between different degrees of freedom. This work explores how such dynamical coupling can be used to make changes in orbit and attitude using internal motions in a controlled manner. The methods outlined here lead to control maneuvers for multibody spacecraft without using chemical fuel. With increasing risks to space assets in Earth orbits from space debris, such control methods are both timely and valuable.

In system dynamics models, distributions for uncertain parameters are required for testing model sensitivity. As well in the same context, it could be used to test sensitivity and robustness for new policies. Moreover, these distributions could be used for confidence intervals estimation and hypothesis testing. Residual bootstrapping technique (RBT) is one of bootstrapping techniques that could be used for estimating parameters distributions for system dynamics models. RBT is a statistical technique based on resampling residuals for fabricating “new historical data”. These new historical data is used to fit the model and get new estimates for the parameters. Repeating this many times will generate many estimates for the parameter(s). In this work a proposed method based on RBT is used to improve the bias that could be resulted from estimation. The commodity cycle model for hogs in USA is used as case study. Some table relationships in this model have been replaced by nonlinear functions. RBT is used for estimating parameters distributions for these nonlinear functions.

The purpose of this monograph is to provide illustrative examples of nonlinear modeling of oceanic and atmospheric dynamics and associated energetic. Particularly,exact solutions for the Navier-Stokes equations and the corresponding energy balance associated with an atmospheric motion around the Earth are presented. Additionally,nonlinear internal gravity waves forming a column of stratified fluid affected by the Earth's rotation are considered. In terms of linear modeling,the energy density was visualized as spinning patterns that appear to be rotating in an anticlockwise sense. Such spinning patterns were compared with the flow around a low-pressure area that is usually being linked with a modeling of hurricanes. In terms of nonlinear analysis,several classes of exact solutions were found.One particular class was visualized as funnels having something in common with the geometric structure of oceanic whirlpools. Up to the present,it remains an open issue where the whirlpools came from and what surprises they may bring to. However,it is recognized that the oceanic whirlpools play a key role in global climate. Additionally,such whirlpools show influence on the atmosphere.

This work explores the dynamics of a three-dimensional four-bar mechanical linkage subject to random external forcing. The Lagrangian formulation of the equations of motion are index-3 stochastic differential-algebraic equations (SDAE) that describe the time evolution of the sample paths of the generalized coordinates, velocities, and Lagrange multipliers as stochastic processes. We numerically solve the SDAEs using two different approaches: inverse dynamics, Case Study 1, via independent, successive solution of the nonlinear equations for each kinematic variable, where the time evolution of one generalized coordinate is prescribed; and direct dynamics, Case Study 2, via direct solution of the SDAEs in the index-1 formulation, using fourth-order stochastic backward differentiation formula (BDF) with modified Newton iteration and position and velocity stabilization, where the (deterministic) input driving torque is prescribed.

Great efforts have been made these last decades to understand phenomena occurring at microscopic scale. At this stage, classical physics alone can not describe the dynamics of a system be it regular or nonlinear complex one. This book deals with the dynamics of classically regular systems under several polynomial and sinusoidal potentials. We both analytically and numerically study the extended semiquantum dynamics through the introduction of quantum fluctuation degrees of freedom in a time dependent variational principle using generalized Gaussian wave function. After a literature review on the topic, the methodology is widely exposed. At last we present the main results of this work on: the cubic-quartic potential with the modulational instability criterion in the case of wave propagation; the triple and multiple well adjustable potential heterostructures; the sinusoidal potential model with the torsional dynamics of butane molecule. The analysis and results presented in this book shall help shed light on these new and exciting mesoscopic investigations, and should be especially useful to researchers in quantum fundamental and experimental physics to prevent unexpected phenomena.

Aircraft System Identification and Control

Most of the practical systems including aircraft system dynamics are nonlinear and stochastic in nature, so the linearized models without having accurate knowledge of noise characteristics to them may lead to inaccurate results and poor performance. In the presence of measurement & process noise, the parameters estimates of dynamic systems are asymptotically biased, inconsistent and inefficient. In the case of state estimation of nonlinear system, researchers have been proposed to design observers using Lyapunov theory based stability analysis. The selection of Lyapunov function is not easy in practice as it does not have specific guidelines for such selection. Contraction theory is an alternative approach to visualize the stability results for nonlinear system, & exploits the incremental behavior of the trajectories of a system with respect to each other. The stability analysis using contraction theory eliminates the selection of Lyapunov function and its extension to stochastic nonlinear system is an active research area. This book is focused on system identification of aircraft system from noisy data, and stability analysis of aircraft system in stochastic contraction framework.

We study the dynamics of solitary waves in the generalized Frenkel-Kontorova (GFK) model, discussed about kink pro?les and energy in the continuum limit of this model and present Some conclusions concerning the interactions of kink in the system.The influence of the Gaussian approximation on the nucleation rate of kink-antikink pairs in a nonlinear deformable chain is performed and a new formula for the nucleation rate of kink-antikink pairs is determined. Using the Kolmogorov method in the GFK model in the presence of external forces and impurities, we set o? analytical expression of the nucleation rate in the system. A Numerical application of this theory is made by using existing data. We end by investigating the role of the applied ?eld on the nucleation process in an inhomogeneous deformable chain. The Hamiltonian formalism allows us to model the system. We derive numerically the depinning threshold ?eld of the system and show the in?uence of the deformability of the impurity potential on this depinning threshold ?eld.

The linear (nonlinear) propagation of the dust-acoustic waves in a nonuniform (two-ion-temperature) dusty plasma has been rigorously investigated. The linear part is aimed to examine the effects of dust density nonuniformity and the polarization force (PF), consists of electrons, ions and inertial arbitrarily charged dust whereas nonlinear part is concerned with solitary waves and double layers with two-ion-temperature plasma. Comprehensive and up-to-date theme of PF inherits from nonuniformity, would substantially assist anyone to gain a thorough knowledge including its mountingly consequential roles in linear wave dynamics. Nonlinear Gardner solitons exist around the critical value. The emphasis of PF is laid more on the fundamental principles as well as its implications, contemporary applications, from recent reviews than on minute details. Our present survey relevant to the electrostatic linear-nonlinear structures observed in cosmic and laboratory plasmas, is of utmost importance.

An experiment and theoretical analysis have been done to measure the nonlinear refractive index n2 of LiNbO3 for different three wavelengths laser light of a continuous Ar-ion laser and observe the variation of the value and sign of the nonlinear refractive index. The Z-scan is a simple technique for measuring the change in phase induced on a laser beam upon propagation through a nonlinear material. It gives both the sign and magnitude of this phase change , which is simply related to the change in index of refraction, . For different wavelength the sign and the value of index of refraction is different. Additionally, for third-order nonlinear responses the real part of the third-order nonlinear susceptibility, , can be measured. However, Z- scan is sensitive to any nonlinear processes which results in , so that great care must be taken in interpreting data taken with this or any other nonlinear materials characterization technique.

Work presented in this book introduce new approaches to designing robust nonlinear controllers for a class of nonlinear uncertain systems. It integrates the conventional feedback linearization method with the robust control schemes such as minimax LQR and minimax LQG controllers in a systematic way. The main objective of this research is to apply the proposed method to the case of an air-breathing hypersonic flight vehicle (AHFV) control problem. In this work, we consider both rigid and flexible nonlinear models of a hypersonic flight vehicle and synthesized velocity and altitude nonlinear tracking controllers by using minimax LQR and minimax LQG controllers. The main reason to use minimax control theory is that it gives a systematic way to design a robust controller and also allows for time varying uncertainty.
