In this dissertation, weiinvestigate the periodic orbitsiof the massive particlesiaround three distinct spacetimes: Schwarzschild black hole, Fisher/Janis-Newman-Winicour (F/JNW) spacetime, and Modified Gravity (MOG) ...

The phenomenon of gravitational lensing in both strong and weak deflection limits is discussed in this thesis. Solutions of Buchdahl’s ODE in R2 gravity are considered as spacetimes in this work. Weak deflection angle ...

The Hindukush region is renowned for its high seismic activity, making it a crucial area for earthquake analysis. This research examines the earthquake data from 2008 to 2010 utilizing sophisticated statistical techniques. ...

This thesis primarily focuses on the study of plane gravitational waves and their collisions, which are exact solutions of the vacuum Einstein field equations. Independently, both Khan and Penrose, as well as Szekeres, ...

Engineers and scientists have recently shown considerable interest in studying the f luid flow and heat transfer around elongating cylinders either for Newtonian or non Newtonian fluids. The interest in this topic ...

This study explores the effectiveness of Convolutional Neural Networks (CNNs) and DenseNet models for binary and multi-class classification tasks using the Kvasir dataset, which consists of gastrointestinal tract images. ...

This thesis investigates the levels of depression, anxiety and stress among univer sity students at the School of Natural Sciences, National University of Sciences and Technology (SNS NUST) Islamabad, using the Depression ...
