Bias Reduction for Dynamic Nonlinear Panel Models with Fixed Effects
Fixed Eff ects Dynamic Nonlinear Panel Models
2015/9/22
The fixed effects estimator of panel models can be severely biased because of well-known incidental parameter
problems. It is shown that this bias can be reduced as T grows with n. We con...

Byusingadoubleperturbationmethodwhichassumesthatbothε andμaresmall,we approximate analytical conditions for the existence and bifurcation of nonlinear quasiperiodic motions in the neighborhood of the ...
Two models for the parametric forcing of a nonlinear oscillator
Parametric excitation Resonance Chaos Elliptic averaging
2015/8/27
Instabilities associated with 2:1 and 4:1 res-onances of two models for the parametric forcing of a strictly nonlinear oscillator are analyzed. The first model involves a nonlinear Mathieu equation an...

Nonlinear Dynamics and Alternative Stable States in Shallow Coastal Systems
Shallow Coastal Systems Nonlinear Dynamics
2015/7/16
The dynamics of shallow-water coastal environments are controlled by external drivers—sea level rise, storms, and sediment and nutrient supplies—and by internal feedbacks. Interactions of biotic proce...

IUTAM SYMPOSIUM 2014 Complexity of Nonlinear Waves
2013/11/29
Wave motion is the key mechanism of interest to many fields of science, such as mechanics, acoustics, seismology, oceanography, coastal and offshore engineering, electromagnetism, etc. Despite an extr...
Nonlinear study of the dynamic behavior of a string-beam coupled system under combined excitation
1:1 internal resonance String-beam Multiple scales Chaotic response Stability
2012/2/28
In this paper, the nonlinear dynamic behavior of a string-beam coupled system subjected to external, parametric and tuned excitations is presented. The governing equations of motion are obtained for t...
