We present a framework for tracking contours in 2D image sequences by taking into account the motion information and correspondence between contour points. With this framework, The tracking problem can be divided into two steps: i) Contour detection using general internal and external energies in separate frames, and ii) Tracking and refining contours using motion information of the entire imag...

Abstract: From an observational point of view, unveiling the physical processes behind the nature of the jets emanating from radio-loud AGN demands the resolution of the structure across the jet with the highest angular resolutions. Relying on a magneto-fluid dynamical description, numerical simulations can help to characterize the internal structure of jets (transversal structure, magnetic fie...

The formation of internal waves from evanescent regions is studied experimentally with a Gaussian topography and varying natural frequency (N) profiles. When a topography is encompassed by an evanescent region, where N is less than the imposed excitation frequency, only evanescent waves are generated. The amplitude of these evanescent waves decay at an exponential rate while traveling verticall...

Within the thermodynamic framework with internal variables, the classical Hamilton’s principle for elastic bodies is extended to inelastic bodies composed of materials whose free energy densities are point functions of internal variables, or the so-termed Green-inelastic bodies, subject to finite deformation and non-conservative external forces. Yet this general result holds true even without t...
