Maps of current density using density-functional methods

The Journal of Chemical Physics, 2008
The performance of several density-functional theory (DFT) methods for the calculation of current densities induced by a uniform magnetic field is examined. Calculations are performed using the BLYP and KT3 generalized-gradient approximations, together with the B3LYP hybrid functional. For the latter, both conventional and optimized effective potential

Invariant densities for noisy maps [PDF]

open access: possiblePhysical Review A, 1991
The invariant density of discrete dynamical systems in the presence of weak Gaussian noise is studied both by means of path integrals and a WKB method. The leading order of the invariant density in the noise strength defines a generalized potential that is a Lyapunov function of the deterministic map.

Perceived density of road maps

Applied Ergonomics, 2014
Maps should be designed so that users can comprehend and use the information. Display decisions, such as choosing the scale at which an area is shown, depend on properties of the displayed information such as the perceived density (PD) of the information. Taking a psychophysical approach we suggest that the PD of information in a road map is related to
