Dynamical Solutions to the Horizon and Flatness Problems [PDF]
, 1993 We discuss in some detail the requirements on an early-Universe model that solves the horizon and flatness problems during the epoch of classical cosmology ($t\ge t_i\gg 10^{-43}\sec$).

Flatness of tracer density profile produced by a point source in turbulence [PDF]
, 2003 The average concentration of tracers advected from a point source by a multivariate normal velocity field is shown to deviate from a Gaussian profile. The flatness (kurtosis) is calculated using an asymptotic series expansion valid for velocity fields ...

A Test for Differential Flatness by Reduction to Single Input Systems [PDF]
, 1995 For nonlinear control systems (p inputs), we present a test for flatness. The method consists of making an initial guess for p-1 of the flat outputs, which may involve parameters still to be determined.

Laser Scanning and the Continuous Wavelet Transform for Flatness Control [PDF]
, 2015 Current methods for surface flatness control in construction are based on sparse measurements and therefore may lead to inaccurate and imprecise results.
