High-Speed Collapse of a Hollow Sphere of Type I Matter (2008)

Ahmad, Zahid, Harada, Tomohiro, Nakao, Ken-ichi, Sharif, M.

In this paper, we study the dynamics of a hollow spherical matter collapsing with very large initial velocity. The spacetime is initially very similar to the Vaidya solution, and the deviations from...

Plane Symmetric Gravitational Collapse (2007)

Sharif, M., Ahmad, Zahid

In this paper, we derive the general formulation by considering two arbitrary plane symmetric spacetimes using Israel's method. As an example, we apply this formulation to known plane symmetric...

High-Speed Cylindrical Collapse of Two Perfect Fluids (2007)

Sharif, M., Ahmad, Zahid

In this paper, the study of the gravitational collapse of cylindrically distributed two perfect fluid system has been carried out. It is assumed that the collapsing speeds of the two fluids are very...

Gravitational Perfect Fluid Collapse With Cosmological Constant (2006)

Sharif, M., Ahmad, Zahid

In this paper, the effect of a positive cosmological constant on spherically symmetric collapse with perfect fluid has been investigated. The matching conditions between static exterior and...

Searching for an appropriate probability distribution for at-site flood frequency analysis in south-east Australia (2005)

Madhavsinh, Jadav J., Ahmad, Zahid

Design flood estimation is often required in hydrologic design, flood risk assessment, and various environmental and ecological studies. Flood frequency analysis is commonly used to estimate design...
