CMB in nonstandard cosmology: A first look
Gunter Scharf
We study CMB in the nonstandard background cosmology recently investigated. Using the previously calculated first order metric perturbations we discuss the Sachs-Wolfe and the inte…
Perturbation theory in nonstandard cosmology
Günter Scharf
We study inhomogeneous perturbations away from the strongly homogeneous background cosmology previously studied. The problem is greatly simplified by using the mapping on the inner…
The hyperbolic heat transfer equation and the ablation problem: Theory and experiment
Gunter Scharf, Lam Dang
We study the ablation problem for the hyperbolic heat equation in an axisymmetrical geometry which can be conveniently realized in the lab. We determine an analytic solution which…
Approach to steady state in the heat equation and the hyperbolic heat transfer equation
Gunter Scharf
We investigate the spherically symmetric 1D ablation problem. We show that the parabolic heat equation fails to describe the approach to steady state in infinite space. The hyperbo…
Dipole density instead of potentials in electrocardiology
Gunter Scharf, Lam Dang
We discuss the forward and inverse problems between the potential V(x) measured in a heart chamber and its sources represented by a dipole density d(y) located on the heart wall. W…
Cosmology with the cosmic rest frame
Günter Scharf
We assume a one-to-one correspondence between comoving coordinates and the cosmic rest frame in a spherically symmetric inhomogeneous universe. This strongly restricts the solution…
