Cost Optimization of Water Distribution Networks: Model Refinement Is Better Than Problem-Specific Solving Techniques
Saumya Goyal, Om Damani, Ashutosh Mahajan
Existing techniques for the cost optimization of water distribution networks either employ meta-heuristics, or try to develop problem-specific optimization techniques. Instead, we…
Facets of a mixed-integer bilinear covering set with bounds on variables
Hamidur Rahman, Ashutosh Mahajan
We derive a closed form description of the convex hull of mixed-integer bilinear covering set with bounds on the integer variables. This convex hull description is determined by co…
Critical Collapse of Einstein Cluster
Ashutosh Mahajan, Tomohiro Harada, Pankaj S. Joshi +1
We observe critical phenomena in spherically symmetric gravitational collapse of Einstein Cluster. We show analytically that the collapse evolution ends either in formation of a bl…
Analytical solutions for black-hole critical behaviour
Tomohiro Harada, Ashutosh Mahajan
Dynamical Einstein cluster is a spherical self-gravitating system of counterrotating particles, which may expand, oscillate and collapse. This system exhibits critical behaviour in…
Rebounce and Black hole formation in a Gravitational Collapse Model with Vanishing Radial Pressure
Ashutosh Mahajan, Pankaj S. Joshi
We examine spherical gravitational collapse of a matter model with vanishing radial pressure and non-zero tangential pressure. It is seen analytically that the collapsing cloud eit…
Cosmic Censorship in Higher dimension II
Ashutosh Mahajan, Rituparno Goswami, Pankaj S. Joshi
Generalizing earlier results on dust collapse in higher dimensions, we show here that cosmic censorship can be restored in gravitational collapse with tangential pressure present i…
