Convection patterns in a spherical fluid shell.
Symmetry-breaking bifurcations have been studied for convection in a nonrotating spherical shell whose outer radius is twice the inner radius, under the influence of an externally applied central force field with a radial dependence proportional to 1/r(5). This work is motivated by the GeoFlow experiment, which is performed under microgravity condition at the International Space Station where t...
متن کاملLocal Casimir Energies for a Thin Spherical Shell
Abstract The local Casimir energy density for a massless scalar field associated with step-function potentials in a 3 + 1 dimensional spherical geometry is considered. The potential is chosen to be zero except in a shell of thickness δ, where it has height h, with the constraint hδ = 1. In the limit of zero thickness, an ideal δ-function shell is recovered. The behavior of the energy density as...
متن کاملThe spherical collapse model with shell crossing
In this work, we study the formation and evolution of dark matter halos by means of the spherical infall model with shell-crossing. We present a framework to tackle this effect properly, that does not involve the adiabatic approximation, and is based on the numerical follow-up, with time, of that individual shell of matter that contains always the same fraction of mass with respect to the total...
متن کاملCell membrane wrapping of a spherical thin elastic shell.
Nanocapsules that can be tailored intelligently and specifically have drawn considerable attention in the fields of drug delivery and bioimaging. Here we conduct a theoretical study on cell uptake of a spherical nanocapsule which is modeled as a linear elastic solid thin shell in three dimensions. It is found that there exist five wrapping phases based on the stability of three wrapping states:...
متن کاملIncompressible viscous fluid flows in a thin spherical shell Linearized stability of incompressible viscous fluid flows in a thin spherical shell is studied by using the two-dimensional Navier-Stokes equations on a sphere. The stationary flow
S 1.2 DONALD CAMPBELL University of Waterloo The Sigma-Delta Modulator as a Chaotic Nonlinear Dynamical System Sigma-Delta modulators (or noise shapers, as they are also called) are extensively used for analogue-to-digital and digital-to-analogue data conversion (signal processing). Their dynamical behaviour can appear chaotic. I will explore this behaviour from the point of view of nonlinear d...
