Materials that undergo internal transformations are usually described in solid mechanics by multi-well energy functions that account for both elastic and transformational behavior. In order to separate the two effects, physicists use instead phase-field-type theories where conventional linear elastic strain is quadratically coupled to an additional field that describes the evolution of the refe...
Nonlinear loudspeaker control opens new degrees of freedom in passive driver design. Transducers having a short voice coil overhang are more sensitive and efficient at low amplitudes than transducers using a linear motor. Nonlinear distortion generated at higher amplitudes can actively be compensated by nonlinear control. This paper investigates the behavior of real loudspeakers under control u...
We construct the classical dynamical system which has a quantum-like behavior. We have shown that the energy-time uncertainty relation takes place for the system and it has purely classical nature. We investigate the behavior of the system and propose a “classical” explanation of Franck-Hertz experiments.
In this brief contribution, which is based on my talk at the conference, I discuss the dynamics of solutions of nonlinear wave equations near the threshold of singularity formation. The heuristic picture of threshold behavior is first presented in a general setting and then illustrated with three examples. Consider an initial value problem du dt = A(u), u(0) = φ ∈ D, (1) where A is a nonlinear ...
This paper offers a new, nonlinear model of informationseeking behavior, which contrasts with earlier stage models of information behavior and represents a potential cornerstone for a shift toward a new perspective for understanding user information behavior. The model is based on the findings of a study on interdisciplinary information-seeking behavior. The study followed a naturalistic inquir...
We study a nonlinear transmission problem for a plate which consists of thermoelastic and isothermal parts. The problem generates a dynamical system in a suitable Hilbert space. Main result is the proof of asymptotic smoothness of this dynamical system and existence of a compact global attractor in special cases.
A three-dimensional numerical computation of magnetohydrodynamic dynamo behavior is described. The dynamo is mechanically forced with a driving term of the Taylor-Green type. The magnetic field development is followed from negligibly small levels to saturated values that occur at magnetic energies comparable to the kinetic energies. Though there is locally a helicity density, there is no overal...
Cells in the vestibular nucleus are assumed to behave as linear systems. We tested this hypothesis by testing the verity of two principles, those of superposition and homogeneity. Recordings were obtained from vestibulo-only cells of two rhesus monkeys undergoing translations, rotations, and off-axis (eccentric) rotations. This was done for several frequencies (1–5 Hz for translation and 1–4 Hz...
The impetus of this study is to investigate the chaotic behavior of a size-dependent nano-beam with double-sided electrostatic actuation, incorporating surface energy effect and intermolecular interactions. The geometrically nonlinear beam model is based on Euler-Bernoulli beam assumption. The influence of the small-scale and the surface energy effect are modeled by implementing the consistent ...
To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according to the radius, and that of a particular radius keeps the initial position. The energy of a...
