Regression splines in the time-dependent coefficient rates model for recurrent event data
(2008)
Many epidemiologic studies involve the occurrence of recurrent events and much attention has been given for the development of modeling techniques that take into account the dependence structure of multiple event data. ...
Anomalous dependence on the diffusion coefficients of the ionic relaxation time in electrolytes
(AMER CHEMICAL SOC, 2008)
We show, by using a numerical analysis, that the dynamic toward equilibrium for an electrolytic cell subject to a step-like external electric field is a multirelaxation process when the diffusion coefficients of positive ...
Stefan problems for the diffusion-convection equation with temperature-dependent thermal coefficients
(Pergamon-Elsevier Science Ltd, 2021-09)
Different one-phase Stefan problems for a semi-infinite slab are considered, involving a moving phase change material as well as temperature dependent thermal coefficients. Existence of at least one similarity solution is ...
SPECTRAL PROPERTIES OF A COUPLED SYSTEM OF SCHRODINGER EQUATIONS WITH TIME-PERIODIC COEFFICIENTS
(KHAYYAM PUBL CO INC, 2012)
We consider a coupled system of Schrodinger equations with time-periodic coefficients
Mean Motion in Stochastic Plasmas With a Space-Dependent Diffusion Coefficient
(WILEY-V C H VERLAG GMBH, 2009)
Radial transport in the tokamap, which has been proposed as a simple model for the motion in a stochastic plasma, is investigated. A theory for previous numerical findings is presented. The new results are stimulated by ...
Diffusion coefficients during osmotic dehydration of tomatoes in ternary solutions
(Elsevier B.V., 2004-02-01)
The apparent diffusion coefficients for sucrose, NaCl and water during osmotic dehydration of tomatoes in ternary solutions were determined. Long time experiments (up to 60 h) were carried out in order to determine equilibrium ...
Integrable NLS equation with time-dependent nonlinear coefficient and self-similar attractive BEC
(Elsevier B.V., 2011-01-01)
We investigate the nonlinear Schrodinger equation with a time-dependent nonlinear coefficient. By means of Painleve analysis we establish the integrability for a particular form of the nonlinear coefficient. The corresponding ...
