The proper analytical solution of the Korteweg-de Vries-Burgers equation
On using variable transformations and proofs of theorems, the asymptotic behaviour and the proper analytical solution of the Korteweg-de Vries-Burgers equation have been found in this letter.
Closed-form heave solutions for expansive soils
During the past decade, the theory for heave prediction has developed within the context of unsaturated soil behavior and has become a valuable tool for geotechnical practice. The laboratory procedures for testing expansive ...
Unsaturated soil consolidation theory and laboratory experimental data
The volume change process of an unsaturated soil was considered as a transient flow problem with water and air flowing simultaneously under an applied stress gradient. laboratory experiments were performed to study the ...
Landau-level width : magnetic-field and temperature dependences
We calculate the effect of level broadening on the steady part of the magnetic moment and specific heat by deriving an analytic expression for the free energy of a two-dimensional electron gas in a uniform magnetic field, ...
Time dependence of a general class of quantum distribution functions
We derive an explicit analytic expression for the time development of a generalized class of quantum distribution functions, which include as special cases the Wigner, the normal, and the antinormal distributions. We find ...
Phase-space representations of the Bloch equation
We discuss the phase-space representation of the Bloch equation and present analytic expressions for two generalized classes of distribution functions. Series solutions to order of ħ2 are given. We conclude that the Wigner ...
Scattering matrix elements of biological particles measured in a flow through system : theory and practice
Light scattering techniques (including depolarization experiments) applied to biological cells provide a fast nondestructive probe that is very sensitive to small morphological differences. Until now quantitative measurement ...
Spectral analysis of flow cytometric data : design of a special-purpose low-pass digital filter
Spectral decomposition of flow cytometric datafiles of arbitrary dimension reveal information of both the signal and the noise components that constitute the histograms. This spectral information is used to construct a ...
Elastic light scattering from nucleated blood cells : rapid numerical analysis
A model is presented to calculate the light-scatter properties of nucleated blood cells which are mimicked by two concentric spheres. The light-scatter characteristics were derived from the Rayleigh-Debye-Gans approximation ...
Surface effects on the diamagnetic susceptibility and other properties of a low temperature electron gas
A general formulation is developed for determining the free energy of a Fermi gas contained in an arbitrary smooth external potential barrier and in a weak magnetic field, in the low-temperature limit. The Wigner phase-space ...
