On dispersion curve coloring for mechanical metafilters. [PDF]
Sci Rep, 2022 AbstractThis paper formalizes smooth curve coloring (i.e., curve identification) in the presence of curve intersections as an optimization problem, and investigates theoretically properties of its optimal solution. Moreover, it presents a novel automatic technique for solving such a problem.

Dispersive geometric curve flows [PDF]
Surveys in Differential Geometry, 2014 The Hodge star mean curvature flow on a 3-dimension Riemannian or pseudo-Riemannian manifold, the geometric Airy flow on a Riemannian manifold, the Schrodingier flow on Hermitian manifolds, and the shape operator curve flow on submanifolds are natural non-linear dispersive curve flows in geometric analysis.

Dispersion curves for the generalized Bernstein modes [PDF]
Journal of Plasma Physics, 1973 Dispersion curves are plotted for the extraordinary branch of the electron- and ion-cyclotron harmonic waves propagating perpendicularly to the static magnetic field in a non-relativistic, hot Maxwellian plasma, without invoking the electrostatic approximation.

On the effect of damping on dispersion curves in plates
International Journal of Solids and Structures, 2013 AbstractThis paper presents a study on quantitative prediction and understanding of time-harmonic wave characteristics in damped plates. Material dissipation is modelled by using complex-valued velocities of free dilatation and shear waves in an unbounded volume. As a numerical example, solution of the classical Rayleigh–Lamb problem for a viscoelastic

Dispersion points and rational curves [PDF]
Proceedings of the American Mathematical Society, 2020 We construct two connected plane sets which can be embedded into rational curves. The first is a biconnected set with a dispersion point. It answers a question of Joachim Grispolakis. The second is indecomposable. Both examples are completely metrizable.

Dispersion curves for thermomechanical waves [PDF]
The Journal of the Acoustical Society of America, 1988 When mechanical deformation and heat conduction are both accounted for, two coupled partial differential equations (PDEs) describe wave propagation in a medium. For one-dimensional wave propagation in a medium without mechanical dissipation, these PDEs yield a dispersion relation of complex quadratic form, which shows that two kinds of waves can ...

Disperse: A General Purpose Program for Creating Dispersion Curves
, 1997 The application of guided waves in NDT can be hampered by the lack of readily available dispersion curves for complex structures. To overcome this hindrance, we have developed a general purpose program that can create dispersion curves for a very wide range of systems and then effectively communicate the information contained within those curves.

CURVES OF THERMODYNAMIC STATES IN SOME FLUIDS WITH DISPERSION
TASK Quarterly, 2017 Variations in the thermodynamic state of a dispersive medium, caused by sound, are studied. A bubbly liquid and a Maxwell fluid are considered as examples. Curves in the plane of thermodynamic states are plotted. They are in fact pictorial images of linear relations of excess pressure and excess density in the acoustic wave which reflect irreversible ...
