DECISION MAKING WITHIN THE INFLUENCE OF SOCIAL MEDIA
(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2026-06-30) AIMEN IJAZ; FA22-BDE-009; LHR TP 10126; Zain Ul Abidin, Huma Maqbool
This study explores that decision making is not an isolated cognitive process of an
individual, rather it is a socially embedded and digitally influenced phenomenon. In a
society, family expectations, cultural values and community approvals shape the
individual’s decisions, making social acceptance central. By looking at societal
interactions and digital environment, the study explores the increasing effects of social
media on the decision making process of Generation Z. This generation is known as
digital natives as they are grown up into a digital era where they are constantly exposed
to a wide range of curated content on social media platforms. This curated content,
likes, comments and comparison on social media increase pressures. These pressures
influence identity expression, routine behavior, lifestyle choices and presentation of
self, often leading young adults to conform, hesitate or prioritize others’ expectations
over personal preference. Hence, their decisions become externally driven. The study
draws on Hazel Rose Markus and Shinobu Kitayama’s concept of the relational self
and Leon Festinger’s social comparison theory, which explain how individuals define
themselves through relationships and evaluate themselves through others. Existing
research shows that social media use increases comparison, anxiety and lower self
esteem.

Finite Element Solution of Time Dependent Partial Differential Equation in Structural Dynamics
(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2025) Sheer Zaman; CIIT/SP24-RMT-024/LHR; Dr. Muhammad Nauman Bashir; LHR TP 10084
This thesis investigates the Finite Element Method (FEM) solution of time dependent Par-tial Differential Equations (PDEs) in structural dynamics, focusing on the transient free vibration of a simply supported elastic cable governed by the one-dimensional wave equa-tion. The primary objective is to numerically model the dynamic behaviour of the structure under various initial conditions and rigorously validate the numerical accuracy, stability, and convergence properties of the selected time integration schemes. The study analysed two distinct vibration modes across three problem configurations:
1. First Mode Vibration (Problems 2 and 3)
The cable was initiated in its first mode shape,
f(x, 0) = sin(pi*x) and released from rest with a wave speed of c = 2m / s This configuration was analyzed using two explicit time step sizes, k = 0.0495 and k = 0.05 to investigate the critical stability condition.
2. Second Mode Vibration (Problem 1) The string was excited in its second mode shape using prescribed initial displacement and velocity conditions,
f(x, 0) = sin(2pi*x) partial f partial t (x, 0) = 2pi * sin(2pi*x) .
The wave speed for this case was c = 1m / s
Mathematical Modeling and Analysis of Pertussis Cough
(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2025) Syed Shan-E- Ahmad; CIIT/SP24-RMT-017/LHR; Dr. Syed Tahir Raza Rizvi; LHR TP 10078
Mathematical modeling of dynamical systems often uses ordinary differential equations to represent how key variables evolve over time. Such models support prediction, inter-pretation, and decision-making in biology, engineering, economics, and environmental science by linking mechanisms to observable outcomes. Stability analysis is central in this setting: it determines whether equilibria persist under perturbations and clarifies long-term behavior, resilience, and the potential impact of interventions.
We apply these tools to a pertussis (whooping cough) model with five compartments: susceptible, latent-immunity, exposed, infectious, and recovered. The formulation in-corporates waning vaccine-induced immunity, reinfection, and disease-induced mortal-ity, and it is proven to be positive, bounded, and forward invariant. The basic repro-duction number Ro is derived via the next-generation matrix method; sensitivity analy-sis shows transmission, progression to infectivity, recovery, and vaccination rates most strongly influence persistence. Local and global stability of the disease-free and endem-ic equilibria are established. A nonstandard finite difference scheme preserves quali-tative dynamics and supports simulations. Numerical experiments confirm the analy-sis and illustrate how parameters shape outbreak magnitude and duration. Finally, an integral sliding mode control acting on vaccination robustly suppresses exposure and infection and can drive elimination under parameter uncertainty and disturbances.

Optical and Thermal Properties of Quantum Corrected AdS Black Hole in Kiselev Spacetime
(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2025) Husnain Hafeez; CIIT/SP24-MSMATH-010/LHR; Dr. Rabia Saleem; LHR TP 10072
In this work, we investigate the optical and thermodynamic properties of a quantum-corrected AdS black hole (BH) in Kiselev spacetime. The study focuses on the effects of key param-eters, including the quantum correction parameter a, the cosmological fluid parameter λ. the electric charge Q, and the entropy correction parameter ẞ, on the Hawking temperature, entropy, specific heat, Gibbs free energy, and BH shadow. The Hawking temperature gen-erally increases with the horizon radius, while the quantum and cosmological parameters enhance the corrected entropy and specific heat, indicating regions of local thermodynamic stability. Analysis of the Gibbs free energy reveals that small black holes (BHs) exhibit global instability, which transitions to stability for larger horizons. The BH shadow and photon sphere are found to expand with increasing a and A, and the infalling matter shows characteristic Doppler-induced darkening. These results highlight how quantum correction parameter a and surrounding cosmological fluid parameter A influence both the thermal behavior and observational features of AdS black holes, providing new insights beyond classical treatments.
