In geotechnical engineering, a scale factor “n” is a numerical ratio that relates the physical properties of a physical model to those of a prototype. The effect of scale factor on the dynamic response of a frame foundation used for high-speed tu

We investigate the cosmological evolution of the universe for a spatially flat FLRW background space within the context of f(T,B) gravity, which is a recently formulated teleparallel theory that connects both f(T) and f(R) gravity under suitable limi

The present study attempts to determine the time dependence of some cosmological parameters in flat space (i.e., a space of zero spatial curvature), in the framework of an anisotropic Kaluza-Klein metric. The field equations for this work have been d

In this present paper, we have investigated the dark energy cosmological model in Bianchi−V I0 spacetime by considering generalised Brans-Dicke theory, self-interacting potential, and a dynamical coupling parameter. For this purpose, we have utilis

A revived figure of teenage Albert Einstein is confronted at the threshold of the second millennium with a problem of a graphical likeness of the Lambert W function-based cosmological equations to a logarithmic-exponential discontinuous function that
