The Importance of Local Variations of Axial Dispersion Coefficients

open access: yesChemical Engineering &Technology, Volume 49, Issue 6, June 2026.
A variable axial dispersion model was implemented and compared with classical axial dispersion models, highlighting the impact of the local variations and demonstrating its importance when surface reaction mechanisms occur. ABSTRACT A variable axial dispersion model (VADM), accounting for local variations in the axial dispersion coefficient, was ...

Sensitivity analysis for HJB equations with an application to a coupled backward-forward system

open access: yes, 2013
In this paper, we analyse the dependence of the solution of Hamilton-Jacobi-Bellman equations on a functional parameter. This sensitivity analysis not only has the interest on its own, but also is important for the mean field games methodology, namely for

Decision‐making factors for variable rate application of seed and fertilizer in precision agriculture systems: A review

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Input management practices within precision agriculture systems have enabled grain and oilseed producers to apply agricultural inputs variably, facilitating resource, yield, and profit optimization. Despite significant progress in variable rate technologies, research comparing different methodologies and comprehensive guidelines to assist ...

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3018-3037, June 2026.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...
