Bifurcation Analysis of Nonlinear Aircraft Dynamics

Journal of Guidance, Control, and Dynamics, 1982
A new approach is presented for analyzing nonlinear and high-a dynamic behavior and stability of aircraft. This approach involves the application of bifurcation analysis and catastrophe theory methodology to specific phenomena such as stall, departure, spin entry, flat and steep spin, nose slice, and wing rock.

Construction and nonlinear dynamic analysis of nonlinear dynamic price model

2009 16th International Conference on Industrial Engineering and Engineering Management, 2009
A nonlinear dynamic price model considering the nonlinear factors between supply and demand was constructed in this paper. And the meanings of each parameters in the model were explained. By using nonlinear dynamic analysis, the system stability conditions were obtained from the analysis of the model.

Nonlinear Dynamic Analysis

2019
To determine the performance of structures facing earthquakes the method which is becoming increasingly significant is nonlinear dynamic analysis. To perform nonlinear dynamic analysis the method used here is incremental dynamic analysis. Range of structural response from elasticity to yielding is being covered and further extended up to dynamic ...

Nonlinear Dynamic Slope Stability Analysis

Journal of Geotechnical Engineering, 1987
A procedure is described for performing nonlinear dynamic slope stability analysis. The method combines updated Lagrangian kinematic relations with a cap‐type, strain‐hardening soil plasticity model in an explicit nonlinear dynamic finite element formulation.

Nonlinear dynamic analysis by Dynamic Relaxation method

Structural Engineering and Mechanics, 2008
Numerical integration is an efficient approach for nonlinear dynamic analysis. In this paper, general category of the implicit integration errors will be discussed. In order to decrease the errors, Dynamic Relaxation method with modified time step (MFT) will be used.

Nonlinear analysis of dynamic signature

Indian Journal of Physics, 2013
Signature is a long trained motor skill resulting in well combination of segments like strokes and loops. It is a physical manifestation of complex motor processes. The problem, generally stated, is that how relative simplicity in behavior emerges from considerable complexity of perception–action system that produces behavior within an infinitely ...

Nonlinear dynamical factor analysis

AIP Conference Proceedings, 2001
A general method for state space analysis is presented where not only underlying factors generating the data are estimated, but also the dynamics behind time series in factor space are modeled. The mappings and the states are all unknown. The nonlinearity of the mappings makes the problem highly underdetermined and thus challenging.

Nonlinear dynamical analysis of speech

The Journal of the Acoustical Society of America, 1996
This paper reports results of the estimation of dynamical invariants, namely Lyapunov exponents, dimension, and metric entropy for speech signals. Two optimality criteria from dynamical systems literature, namely singular value decomposition method and the redundancy method, are used to reconstruct state space trajectories of speech and make ...

Nonlinear flight dynamics analysis

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1998
This introduction has two aims. First, it begins the issue with an overview of how modern nonlineardynamics analysis techniques may be of benefit to the flight dynamicist.

Nonlinear Dynamics Analysis through Molecular Dynamics Simulations

2004
A general goal in multiscale modeling is to analyze macroscale (system-level) phenomena using information on the system at the microscale. In this pedagogical note we revisit the time-stepper approach to performing nonlinear dynamics analysis through the use of a microscopic simulator, molecular dynamics in this case. Using simple illustrative examples
