Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Large eddy simulation of aircraft at affordable cost: a milestone in computational fluid dynamics
Flow, 2021 Graphical Abstract Abstract While there have been numerous applications of large eddy simulations (LES) to complex flows, their application to practical engineering configurations, such as full aircraft models, have been limited to date.

Fluid dynamics simulations show that facial masks can suppress the spread of COVID-19 in indoor environments. [PDF]
AIP Advances, 2020 The Coronavirus disease outbreak of 2019 has been causing significant loss of life and unprecedented economical loss throughout the world. Social distancing and face masks are widely recommended around the globe in order to protect others and prevent the

Kelvin-Helmholtz instability is the result of parity-time symmetry breaking
, 2018 Parity-Time (PT)-symmetry is being actively investigated as a fundamental property of observables in quantum physics. We show that the governing equations of the classical two-fluid interaction and the incompressible fluid system are PT-symmetric, and ...

Can a toilet promote virus transmission? From a fluid dynamics perspective
The Physics of Fluids, 2020 Currently, a novel coronavirus named “SARS-CoV-2” is spreading rapidly across the world, causing a public health crisis, economic losses, and panic. Fecal–oral transmission is a common transmission route for many viruses, including SARS-CoV-2.

Comparative Analysis of Right Ventricle Fluid Dynamics
Frontiers in Bioengineering and Biotechnology, 2021 The right and left sides of the human heart operate with a common timing and pump the same amount of blood. Therefore, the right ventricle (RV) presents a function that is comparable to the left ventricle (LV) in terms of flow generation; nevertheless ...

Suppression of elliptic flow in a minimally viscous quark-gluon plasma
, 2007 We compute the time evolution of elliptic flow in non-central relativistic heavy-ion collisions, using a (2+1)-dimensional code with longitudinal boost-invariance to simulate viscous fluid dynamics in the causal Israel-Stewart formulation.
