Alternative formulations to compute the binary shape Euler number

open access: yesIET Computer Vision, 2014
The authors propose two equations based on the pixel geometry and connectivity properties, which can be used to compute, efficiently, the Euler number of a binary digital image with either thick or thin boundaries.

SPATIAL HAMILTONIAN IDENTITIES FOR NONLOCALLY COUPLED SYSTEMS

open access: yesForum of Mathematics, Sigma, 2018
We consider a broad class of systems of nonlinear integro-differential equations posed on the real line that arise as Euler–Lagrange equations to energies involving nonlinear nonlocal interactions.

Incompressible limit for non-isentropic compressible Euler-Navier-Stokes two-phase flow model in R^3

open access: yesElectronic Journal of Differential Equations
This article concerns the incompressible limit for the two-phase flow model consisting of the compressible isothermal Euler equations coupled with compressible non-isentropic Navier-Stokes equations through a drag forcing term. For the 3D Cauchy problem,

Note on the q-Extension of Barnes' Type Multiple Euler Polynomials

open access: yesJournal of Inequalities and Applications, 2009
We construct the q-Euler numbers and polynomials of higher order, which are related to Barnes' type multiple Euler polynomials. We also derive many properties and formulae for our q-Euler polynomials of higher order by using the multiple integral ...

Bounds for Euler from vorticity moments and line divergence [PDF]

open access: yes, 2013
The inviscid growth of a range of vorticity moments is compared using Euler calculations of anti-parallel vortices with a new initial condition.

Estimating Euler equations [PDF]

open access: yes
In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of preference parameters.
