    Dynamics of Women’s Domestic Autonomy and Decision-Making
    (UMT.Lahore, 2021) Anam Zahra
    Every person is independent to contribute to decisions that express his/her life. In most Asian societies like Pakistan, women have a low level of autonomy and decision-making power because of their low socio-economic, cultural norms, and patriarchal society; because of that, women have participated less in the decision-making generally and particularly in the house. The magnitudes of women’s autonomy in situations of isolated flexibility, to acquire economic assets and participation in family decisions and their suggestion about fertility and contraceptive behaviour were examined. The present study was about thesis “Dynamics of Women’s Domestic Autonomy and Decision-Making : A Study of Urban Dera Ghazi Khan” . This research study aims to know how much lack of involvement in decision-making influences women's capabilities and which factors affect women's ability to participate in the decision-making process in the household and family.

    Fourth order numerical method for the solution of heat equation with nonlocal boundary condition
    (UMT Lahore, 2017-12-15) Anam Zahra
    In this thesis, a numerical technique is developed for solving one-dimensional parabolic partial differential equation (PDE) with integral boundary conditions. The spatial derivative is approximated by a finite difference (FD) scheme, and by applying the method of lines, resulting in a system of ordinary differential equations (ODEs). Simpson’s 1/3 rule is used to tackle integral boundary conditions, and it also helps in removing additional variables to produce a system of N equations with N variables. This numerical method can be coded in sequential as well as parallel computing environments.

    The study of relativistic objects in higher dimensions
    (UMT Lahore, 2024-09-03) Anam Zahra
    This thesis is focused on iterative methods for gravitational collapse in higher dimensions. frameworks are developed for the post-quasistatic regime using non-comoving co- ordinate system. various types of fluids, including isotropic and dissipative fluids with free streaming radiation, heat flux, and viscosity are considered here. non-adiabatic distributions are employed with an equation of state that accounts for anisotropy caused by electric charge. dissipation is carried out by streaming-out and diffusion approximations. in non-comoving coordinates, the higher-dimensional interior solution is matched with the Vaidya spacetime for uncharged spheres and the Reissner-Nordstr ̈om solution for charged spheres in the exterior. the generalized form of the post-quasistatic approximation yields a system of higher-dimensional surface equations, which are crucial for understanding physical phenomena such as luminosity, doppler shift, and redshift at the boundary surface of gravitating sources. five-dimensional frameworks for spherically symmetric charged and uncharged com- pact objects with anisotropic fluids are proposed that allows the conformal motion. the behavior of models characteristic pressure, stress, density profile, and surface tension is investigated with the inclusion of a particular density profile and linear equation of state for the higher-dimensional Einstein’s field equations. all the physical parameters are well- behaved for the presented solutions in higher dimensions. the analysis predicts the possible existence of compact stars in five dimensions and, more likely, strange quark stars.
