Inertial forces and dissipation on accelerated boundaries
Inertial forces dissipation accelerated boundaries
font style='font-size:12px;'>
2010/12/22
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in $1+1$, $2+1$, and $3+1$ dimensions. These matter fields describe the internal degrees...
Flaring Solar Hale Sector Boundaries

When, in turn-of-the-20th-century America, Alfred L. Kroeber continued the work of Franz Boas, in establishing anthropology as an academic discipline in the US, he defined culture as a phenomenon sui ...
Pseudodifferential operators on manifolds with foliated boundaries
Pseudodifferential operators manifolds with foliated boundaries
font style='font-size:12px;'>
2010/12/9
Let X be a smooth compact manifold with boundary. For smooth foliations on the boundary of X admitting a ‘resolution’ in terms of a fibra-tion, we construct a pseudodifferential calculus generalizing ...
Spectral Properties of Grain Boundaries at Small Angles of Rotation
Schr¨odinger operators eigenvalues spectral gaps
font style='font-size:12px;'>
2010/12/9
We study some spectral properties of a simple two-dimensional model for small angle defects in crystals and alloys. Starting from a periodic potential V : R2 → R, we let V#(x, y) = V (x, y) in the rig...
Boundaries of escaping Fatou components
Boundaries Fatou components

2010/12/10
Let f be a transcendental entire function and U be a Fatou com-ponent of f. We show that if U is an escaping wandering domain of f, then most boundary points of U (in the sense of harmonic measure) ar...
On stability of rolls near the onset of convection in a layer with stress-free boundaries
stress-free boundaries linear stability
font style='font-size:12px;'>
2010/4/2
We consider a classical problem of linear stability of convective rolls in a plane layer with stress-free horizontal boundaries near the onset of convection. The problem has been studied by a number o...
Centrifugally driven convection in the rotating cylindrical annulus with modulated boundaries
Centrifugally driven convection cylindrical annulus modulated boundaries

2009/11/12
The effect of sinusoidally modulated conical end boundaries on convection in a rotating cylindrical annulus is investigated theoretically and experimentally. A quasiperiodic time dependence of convect...

2009/11/9
In this paper we present an algorithm based on wavelet multiscale decomposition, designed to detect lines of maximal gradients in horizontal direction within two-dimensional data sets. The algorithm i...
