Probabilistic Prediction of Coalescence Flutter Using Measurements: Application to the Flutter Margin Method
Sandip Chajjed, Mohammad Khalil, Dominique Poirel +2
Zimmerman and Weissenburger's flutter margin method is widely used to estimate the aeroelastic coalescence flutter speed. In contrast to aeroelastic decay rates, the flutter margin…
Encoding nonlinear and unsteady aerodynamics of limit cycle oscillations using nonlinear sparse Bayesian learning
Rimple Sandhu, Brandon Robinson, Mohammad Khalil +3
This paper investigates the applicability of a recently-proposed nonlinear sparse Bayesian learning (NSBL) algorithm to identify and estimate the complex aerodynamics of limit cycl…
Robust Bayesian state and parameter estimation framework for stochastic dynamical systems with combined time-varying and time-invariant parameters
Philippe Bisaillon, Brandon Robinson, Mohammad Khalil +3
We consider state and parameter estimation for a dynamical system having both time-varying and time-invariant parameters. It has been shown that the robustness of the Markov Chain…
Domain Decomposition of Stochastic PDEs: Development of Probabilistic Wirebasket-based Two-level Preconditioners
Ajit Desai, Mohammad Khalil, Chris L. Pettit +2
Realistic physical phenomena exhibit random fluctuations across many scales in the input and output processes. Models of these phenomena require stochastic PDEs. For three-dimensio…
Scalable Computational Algorithms for Geo-spatial Covid-19 Spread in High Performance Computing
Sudhi P. V., Victorita Dolean, Pierre Jolivet +4
A nonlinear partial differential equation (PDE) based compartmental model of COVID-19 provides a continuous trace of infection over space and time. Finer resolutions in the spatial…
Behavior of anisotropic fluids with Chaplygin equation of state in Buchdahl spacetime
Amit Kumar Prasad, Jitendra Kumar, Abhijit Sarkar
In the present study we have proposed a new model of an anisotropic compact star which admits the Chaplygin equation of state. For this purpose, we consider Buchdahl ansatz. We obt…
