Boundary-Layer Analysis of Repelling Particles Pushed to an Impenetrable Barrier

چکیده
This paper considers the equilibrium positions of $n$ particles in one dimension. Two forces act on particles; a nonlocal repulsive particle-interaction force and an external which pushes them to impenetrable barrier. While continuum limit as $n \to \infty$ is known for certain class potentials, numerical simulations show that discrete boundary layer appears at barrier, i.e., $o(n)$ do not fit particle density predicted by limit. In this we establish first-order $\Gamma$-convergence result guarantees these converge specific boundary-layer profile.

Reaction Diffusion and Ballistic Annihilation near an Impenetrable Boundary
The behavior of the single-species reaction process A + A → O is examined near an impenetrable boundary, representing the flask containing the reactants. Two types of dynamics are considered for the reactants: diffusive and ballistic propagation. It is shown that the effect of the boundary is quite different in both cases: diffusion-reaction leads to a density excess, whereas ballistic annihila...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

In this paper, the boundary layer flow of an Eyring-Powell non-Newtonian fluid over a linearly stretching sheet is solved using the combination of the quasilinearization method and the Fractional order of Rational Chebyshev function (FRC) collocation method on a semi-infinite domain. The quasilinearization method converts the equation into a sequence of linear equations then, using the FRC coll...
متن کاملThe deep fascia of the thigh forms an impenetrable barrier to fluid injected subcutaneously by autoinjectors.
Needle projection was measured from where the needle protruded from the plastic casing to the proximal edge of the needle lumen. Fluid jet velocity through the EAI at 21 C was determined by calculating the [distance moved by the plunger]/[injection time] [plunger cross-sectional area]/[needle lumen area]. Injection time is from start to finish of the plunger movement. n 1⁄4 3. *Mann-Whitney U t...
