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.

Deep learning algorithms for design of periodic structures and dispersion curves calculation
Research and Review Journal of Nondestructive Testing, 2023 Periodic structure is useful and powerful tool for the wave manipulation. The development of design and analysis of periodic structures using traditional methods (analysis of eigenfrequencies by the finite element method) takes quite a lot of time ...

On dispersion curve coloring for mechanical metafilters
Scientific Reports, 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.
