Evaluating Fast Adaptability of Neural Networks for Brain-Computer Interface

Autor: Sharma, Anupam, Miyapuram, Krishna

Electroencephalography (EEG) classification is a versatile and portable technique for building non-invasive Brain-computer Interfaces (BCI). However, the classifiers that decode cognitive states from EEG brain data perform poorly when tested on newer

Solving fluid flow problems in space-time with multiscale stabilization: formulation and examples

Autor: Khara, Biswajit, Dyja, Robert, Saurabh, Kumar, Sharma, Anupam, Ganapathysubramanian, Baskar

We present a space-time continuous-Galerkin finite element method for solving incompressible Navier-Stokes equations. To ensure stability of the discrete variational problem, we apply ideas from the variational multi-scale method. The finite element

Criteria for dynamic stall onset and vortex shedding in low Reynolds number flows

Autor: Sudharsan, Sarasija, Sharma, Anupam

Publikováno v: Journal of Fluid Mechanics 996, A11 (2024)

Dynamic stall at low Reynolds numbers, $\mathit{Re} \sim \mathcal{O}(10^4)$, exhibits complex flow physics with co-existing laminar, transitional, and turbulent flow regions. Current state-of-the-art stall onset criteria use parameters that rely on f

Space-time finite element analysis of the advection-diffusion equation using Galerkin/least-square stabilization

Autor: Khara, Biswajit, Saurabh, Kumar, Dyja, Robert, Sharma, Anupam, Ganapathysubramanian, Baskar

We present a full space-time numerical solution of the advection-diffusion equation using a continuous Galerkin finite element method. The Galerkin/least-square method is employed to ensure stability of the discrete variational problem. In the full s

Novel ultrasonic bat deterrents based on aerodynamic whistles

Autor: Zeng, Zhangming, Sharma, Anupam

Novel ultrasonic bat deterrents based on aerodynamic whistles are investigated experimentally and numerically. The baseline deterrent, a single-whistle design inspired by Beeken [1], is examined first. It consists of two resonating cavities/chambers.
