A universal transportation model for reverse osmosis systems
(Computers & Chemical Engineering, 2021)
This paper presents a new transport model for reverse osmosis (RO) systems, which combines irreversible thermodynamics, together with solution-diffusion theory. The simplifications adopted by the classical theory for ...
Saddle Point Optimality Criteria and Duality for Convex Continuous-Time Programming Problem
(Department of Mathematics, Faculty of Science and Mathematics, University of Niš, 2022)
In this paper, convex continuous-time programming problem with inequality type of constraints is considered. We derive new saddle point optimality conditions and classical duality results such as weak and strong duality ...
Optimization of modifier deposition on the alumina surface to enhance mechanical properties and cavitation resistance
(Springer, New York, 2020)
Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with ...
