Local metamaterials and transition layers
Kimya Yadollahpour, Hossein Khodavirdi, Ankit Srivastava
In this paper, we elucidate the concept of local acoustic metamaterials. These are composites which exhibit equi-frequency contours (EFC) which correspond to those expected of homo…
Operator theoretic causality analysis of fluid flows using linearized dynamics
Ankit Srivastava, Victor Jimenez-Fernandez, Louis Cattafesta +1
This paper presents an operator-theoretic framework, Linear Operator Causality Analysis (LOCA), for analyzing causality in linearized dynamical systems, focusing here on fluid flow…
Generative AI in Live Operations: Evidence of Productivity Gains in Cybersecurity and Endpoint Management
James Bono, Justin Grana, Kleanthis Karakolios +2
We measure the association between generative AI (GAI) tool adoption and four metrics spanning security operations, information protection, and endpoint management: 1) number of se…
Linear and nonlinear Granger causality analysis of turbulent duct flows
Barbara Lopez-Doriga, Marco Atzori, Ricardo Vinuesa +3
This research focuses on the identification and causality analysis of coherent structures that arise in turbulent flows in square and rectangular ducts. Coherent structures are fir…
The Atomistic Green's Function method for acoustic and elastic wave-scattering problems
Hossein Khodavirdi, Zhun-Yong Ong, Ankit Srivastava
In this paper, we present a powerful method (Atomistic Green's Function, AGF) for calculating the effective Hamiltonian of acoustic and elastic wave-scatterers. The ability to calc…
