A nested hierarchy of second order upper bounds on system failure probability
Sourangshu Ghosh, Baidurya Bhattacharya
For a coherent, binary system made up of binary elements, the exact failure probability requires knowledge of statistical dependence of all orders among the minimal cut sets. Since…
Heat pump without particle transport or external work on the medium achieved by differential thermostatting of the phase space
Puneet Kumar Patra, Baidurya Bhattacharya
We propose a new mechanism that enables heat flow from a colder region to a hotter region without necessitating either particle transport or external work on the conductor, thereby…
Fracture resistance of zigzag single walled carbon nanotubes
Qiang Lu, Baidurya Bhattacharya
Brittle fracture is one of the important failure modes of Single-Walled Carbon Nanotube (SWNT) due to mechanical loading. In this paper, the fracture resistance of zigzag SWNTs wit…
Effect of randomly occurring Stone-Wales defects on mechanical properties of carbon nanotubes using atomistic simulation
Qiang Lu, Baidurya Bhattacharya
While CNTs are found to have ultra high stiffness and strength, an enormous scatter is also observed in available laboratory results. This paper studies the effects of randomly dis…
The Extremal Index and the Maximum of a Dependent Stationary Pulse Load Process Observed above a High Threshold
Baidurya Bhattacharya
Observing a load process above high thresholds, modeling it as a pulse process with random occurrence times and magnitudes, and extrapolating life-time maximum or design loads from…
Performance metrics in a hybrid MPI-OpenMP based molecular dynamics simulation with short-range interactions
Anirban Pal, Abhishek Agarwala, Soumyendu Raha +1
We discuss the computational bottlenecks in molecular dynamics (MD) and describe the challenges in parallelizing the computation intensive tasks. We present a hybrid algorithm usin…
