AIChE Journal, Volume 69, Issue 2, February 2023., 2023 Abstract The design of economically feasible and profitable production processes has driven companies toward integrated continuous manufacturing by reducing working volumes and increasing operating frequencies. Thus, the development of robust small‐scale devices capable of multivariate process optimization is essential.

Vortex Solutions for Thermohaline circulation Equations [PDF]
Journal of Mahani Mathematical Research, 2023 The main objective of this article is to establish a new model and find some vortex axisymmetric solutions of finite core size for this model. We introduce the hydrodynamical equations governing the atmospheric circulation over the tropics, the ...

Entropy of Eigenfunctions [PDF]
, 2009 We study the high--energy limit for eigenfunctions of the laplacian, on a compact negatively curved manifold. We review the recent result of Anantharaman-Nonnenmacher giving a lower bound on the Kolmogorov-Sinai entropy of semiclassical measures, and improve this lower bound in the case of variable negative curvature.

Method for determining eigen numbers in heat conduction problems for a cylinder
Известия высших учебных заведений: Проблемы энергетики, 2023 RELEVANCE. Due to the difficulties of finding eigenvalues and proper functions for bodies with axial (cylinder) and central (ball) symmetries defined in classical methods from the edge Sturm-Liouville problems, including Bessel equations whose exact ...

Journal of Computational Chemistry, Volume 44, Issue 3, Page 149-158, January 30, 2023., 2023 The charge displacement analysis is employed on a series of terminal end‐on transition metal dinitrogen complexes. The results provide a measure for the strength of the σ donation and π backdonation. Calculations with a point charge are used to simulate the electrostatic effect in dinitrogen complexes and the influence of the three interactions an on ...

Journal of Computational Chemistry, Volume 44, Issue 3, Page 367-380, January 30, 2023., 2023 Exchange interactions in polynuclear Fe (III) compounds are derived from ab initio calculations based on a single spin‐flip (1SF) approach. Abstract Low‐energy spectra of single‐molecule magnets (SMMs) are often described by Heisenberg Hamiltonians.

Higher-spin initial data in twistor space with complex stargenvalues
Journal of High Energy Physics, 2020 This paper is a supplement to and extension of arXiv:1903.01399. In the internal twistor space of the 4D Vasiliev’s higher-spin gravity, we study the star-product eigenfunctions of number operators with generic complex eigenvalues.
