Formation of dry granular fronts and watery tails in debris flows [PDF]
E3S Web of Conferences, 2023 Debris flows are particle-fluid mixtures that pose a significant hazard to many communities throughout the world. Bouldery debris flows are often characterized by a deep dry granular flow front, which is followed by a progressively thinner and ...

Multistability in Horizontal Platform System with and without Time Delays
Shock and Vibration, 2018 Chaotic behavior and bifurcation analysis of horizontal platform systems (HPS) have been investigated widely by many researchers. However, the multistable features of such systems have not been investigated, and hence we identified the multistable ...

p-Regular nonlinear dynamics [PDF]
Doklady Mathematics, 2014 This article is devoted to the investigation of a periodic problem of the following form: \[ \dot{x}=f(\mu, x),\; x(0)=x(\tau),\eqno{(1)} \] where \(f\in C^{p+1} (\mathbb R\times\mathbb R^n)\to \mathbb R^n\) and \(f(\mu,x^\ast)=0\) for all \(\mu\in \mathbb R\).

Chaotic Dynamics of an Airfoil with Higher-Order Plunge and Pitch Stiffnesses in Incompressible Flow
Complexity, 2019 Dynamical properties of a two-dimensional airfoil model with higher-order strong nonlinearities are investigated. Firstly, a state-space model is derived considering the plunge and pitch stiffnesses as generalized functions.

Nonlinear quantum dynamics [PDF]
, 2006 The vast majority of the literature dealing with quantum dynamics is concerned with linear evolution of the wave function or the density matrix. A complete dynamical description requires a full understanding of the evolution of measured quantum systems, necessary to explain actual experimental results.

Nonlinear DNA dynamics: Nonlinearity versus dispersion [PDF]
Applied Mathematics and Computation, 2013 In the present paper we study the impact of dispersion and nonlinearity on DNA dynamics. We rely on the helicoidal Peyrard-Bishop model and use the fact that nonlinear DNA dynamics represents an interplay between nonlinearity and dispersion. We state that a dispersion coefficient and a coefficient of nonlinearity, existing in nonlinear Schrödinger ...
