Packed bed absorption column: Hydrodynamics and mass transfer [PDF]

open access: yesActa Periodica Technologica, 2019
This paper presents the results of the determination of the hydrodynamic characteristics and mass transfer in the pilot plate absorption column. The experimental values of the pressure drop in the countercurrent flow of air and water through the

A least-squares method for a Monge-Ampère equation with non-quadratic cost function applied to optical design

open access: yes, 2019
Freeform optical surfaces can transfer a given light distribution of the source into a desired distribution at the target. Freeform optical design problems can be formulated as a Monge-Ampère type differential equation with transport boundary condition ...

On the second order effect of the springing response of large blunt ship

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2015
The springing response of a large blunt ship was considered to be influenced by a second order interaction between the incoming irregular wave and the blunt geometry of the forebody of the ship.

Structured interpolation for multivariate transfer functions of quadratic-bilinear systems

open access: yesAdvances in Computational Mathematics
AbstractHigh-dimensional/high-fidelity nonlinear dynamical systems appear naturally when the goal is to accurately model real-world phenomena. Many physical properties are thereby encoded in the internal differential structure of these resulting large-scale nonlinear systems.

Linear decomposition of the optical transfer function for annular pupils

open access: yes, 2017
A technique for decomposing the Optical Transfer Function (OTF) into a novel set of basis functions has been developed. The decomposition provides insight into the performance of optical systems containing both wavefront error and apodization, as well as

RBF interpolation of boundary values in the BEM for heat transfer problems [PDF]

open access: yes, 2003
[Abstract]: This paper is concerned with the application of radial basis function networks (RBFNs) as interpolation functions for all boundary values in the boundary element method (BEM) for the numerical solution of heat transfer problems.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones

open access: yesAdvanced Engineering Materials, EarlyView.
A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Optimal control of multiphase steel production

open access: yesJournal of Mathematics in Industry, 2019
An optimal control problem for the production of multiphase steel is investigated that takes into account phase transformations in the steel slab. The state equations are a semilinear heat equation coupled with an ordinary differential equation, that ...
