New stochastic model for dispersion in heterogeneous porous media: 1. Application to unbounded domains
A new model of solute dispersion in porous media that avoids Fickian assumptions and that can be applied to variable drift velocities as in non-homogenous or geometrically constricted aquifers, is presented. A key feature ...
Optimisation of a buyer’s sourcing strategy in the mixed auction/direct supply of New Zealand wool
(Lincoln University, 2009)
The New Zealand Wool Industry (NZWI) contributes over a billion dollars a year to NZ gross output. However, this industry is at a crossroads and the incumbent practitioners are looking for ways to increase the value of the ...
Closed form solution of an exponential kernel integral equation
(Scientific Journals International, 2007)
In this note a Fredholm integral equation of the first kind with exponential expressions for the kernel and right hand side is considered. The task of finding a practically usable solution to such an equation may need ...
Iterative solution of quadratic tensor equations for mutual polarisation
(Hindawi Publishing, 2002)
To describe mutual polarisation in bulk materials containing high polarisability molecules, local fields beyond the linear approximation needs to be included. A second order tensor equation is formulated that describes ...
On modelling the drying of porous materials: analytical solutions to coupled partial differential equations governing heat and moisture transfer
(Hindawi Publishing, 2005)
Luikov's theory of heat and mass transfer provides a framework to model drying porous materials. Coupled partial differential equations governing the moisture and heat transfer can be solved using numerical techniques, and ...
On the functional diversity of dynamical behaviour in genetic and metabolic feedback systems
(BioMed Central Ltd., 2009-05-11)
Background: Feedback regulation plays crucial roles in the robust control and maintenance of many cellular systems. Negative feedbacks are found to underline both stable and unstable, often oscillatory, behaviours. We ...
