In this paper, we consider a multi-lithology diffusion model used in stratigraphic modelling to simulate large scale transport processes of sediments described as a mixture of lithologies. This model is a simplified one for which the surficial fluxes are proportional to the slope of the topography and to a lithology fraction with unitary diffusion coefficients. The main unknowns of the system are the sediment thickness , the surface concentrations in lithology of the sediments at the top...
In this paper, we consider a multi-lithology diffusion model used in stratigraphic modelling to simulate large scale transport processes of sediments described as a mixture of L lithologies.
This model is a simplified one for which the surficial fluxes are proportional
to the slope of the topography and to a lithology fraction with unitary diffusion coefficients.
The main unknowns of the system are the sediment thickness h,
the L surface concentrations in lithology i of the sediments
at the...
Electro-muscular disruption (EMD) devices such as TASER M26 and
X26 have been used as a less-than-lethal weapon. Such EMD devices
shoot a pair of darts toward an intended target to generate an
incapacitating electrical shock. In the use of the EMD device,
there have been controversial questions about its safety and
effectiveness. To address these questions, we need to investigate
the distribution of the current density J inside the target
produced by the EMD device. One approach is to develop a
computational...
The swelling and shrinkage of biological tissues are modelled by a four-component mixture theory [J.M. Huyghe and J.D. Janssen, Int. J. Engng. Sci.35 (1997) 793–802; K. Malakpoor, E.F. Kaasschieter and J.M. Huyghe, Mathematical modelling and numerical solution of swelling of cartilaginous tissues. Part I: Modeling of incompressible charged porous media.
ESAIM: M2AN41 (2007) 661–678]. This theory results in a coupled system of nonlinear parabolic differential equations together with an algebraic...
