Nonlinear Dynamical Analysis of Normal Voices
Seventh IEEE International Symposium on Multimedia (ISM'05), 2006Human voice has been the focus of study for different areas of sciences. Researches in the last two decades have established the existence of chaos in human voice production. The purpose of this paper is to use nonlinear dynamics methods in the analysis of normal voices from healthy subjects and correlate them to traditional acoustic parameters as well

Nonlinear analysis of dynamic force microscopy
2006 American Control Conference, 2006Dynamic force microscopy is a powerful tool to image non-conductive materials with atomic resolution using the nonlinear interaction force. A perturbation method is extended to analyze the nonlinear oscillation dynamics of the frequency modulation dynamic force microscopy.

Construction and nonlinear dynamic analysis of nonlinear dynamic price model
2009 16th International Conference on Industrial Engineering and Engineering Management, 2009A 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.

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 Analysis of Pathological Voices
2013Research on the human health evaluation through sound analysis is now attracting more and more researchers in the world. Acoustic analysis could be a useful tool to diagnose the disease. Therefore, pathological voices can be used to evaluate the health status as a complementary technique, such as bronchitis.

Nonlinear dynamical analysis of speech
The Journal of the Acoustical Society of America, 1996This 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 analysis of dynamic signature
Indian Journal of Physics, 2013Signature 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, 2001A 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.
