We study the numerical anisotropy existent in compact difference schemes as applied to hyperbolic partial differential equations, and propose an approach to reduce this error and to improve the stability restrictions based on a previous analysis applied to explicit schemes. A prefactorization of compact schemes is applied to avoid the inversion of a large matrix when calculating the derivatives...

Abstract The 2022 meeting of the American Academy Religion in Denver featured a book panel on Dana W. Logan’s Awkward Rituals: Sensations Governance Protestant America (University Chicago Press, 2022). This essay introduces forum based panel, featuring four scholars representing diverse subfields religious studies: Ian MacCormack, Charles McCrary, Constance Furey, and Marko Geslani. It argues t...

We introduce two kinds of explicit solutions to the convection-reaction equation, ut + (|u| /q)x = u, u, x ∈ R, t ∈ R , q > 1, and employ them to test properties of various computational schemes. From this test we observe that computed solutions using Lax-Friedrichs, MacCormack and Lax-Wendroff schemes break down in a finite time. On the other hand some other schemes including WENO, NT and Godu...

The article is devoted to the analysis of semantics and features functioning textual bond "bolee togo" [moreover]. aim work was identify specifics this bond, taking into account its semantic in texts various functional styles genres. Moreover, following research methods have been applied comprehend bond: traditional descriptive method, including observation, generalization systematization lingu...

Due to the wide application of Delaware nozzle in many fields, flow characteristics subsonic-supersonic isentropic De-Laval are analyzed numerically. The can be simplified a quasi-one-dimensional problem. First, MacCormack format is employed discretize control equations conservative form. Then, results with and without artificial viscosity compared. Grid independence also discussed. show that n...
