Extended theories of gravity: the early universe and stellar interiors by Campbell, Mariam

“…In the study of relativistic stars, this thesis presents two new exact, physically viable solutions to the Tolman–Oppenheimer–Volkoff (TOV) equations within extended gravity models. For theories with a quadratic correction to the Einstein–Hilbert action, the solutions describe (1) a quasi-isotropic stellar configuration with a shell and double-layer structure resembling a dipole distribution, and (2) a configuration characterized by a quartic correction to the Newtonian potential and a smooth boundary matching. …”

Computational analysis of viscoelastic fluid dynamics with applications to heat exchangers by Mavi, Anele

“…Non-Newtonian viscoelastic fluids in heat exchanger arrangements are encountered in various industrial applications such as power generation, refrigeration and in the food processing industry where the need for cooling and heating of liquids is required. The model problem is governed by complex, non-linear and coupled partial differential equations. …”

Shadows of a Schwarzschild Black Hole Surrounded by a Spherically Symmetric Dark Matter by Ibrahim, Ahmad

“…In this thesis, using general relativity, the null geodesics and black hole shadow of a spherically symmetric configuration of a black hole (surrounded by a dark matter shell) are studied. First, the standard results of the photon sphere of Schwarzschild de-Sitter black hole is revisited and analyzed more carefully. …”

Aspects of amplitudes, gravity & complexity by Moynihan, Nathan
