Tight Chang's-lemma-type bounds for Boolean functions
Sourav Chakraborty, Nikhil S. Mande, Rajat Mittal +3
Chang's lemma (Duke Mathematical Journal, 2002) is a classical result with applications across several areas in mathematics and computer science. For a Boolean function that ta…
On algorithms to find p-ordering
Aditya Gulati, Sayak Chakrabarti, Rajat Mittal
The concept of p-ordering for a prime p was introduced by Manjul Bhargava (in his PhD thesis) to develop a generalized factorial function over an arbitrary subset of integers. This…
Quantitative analysis of the kinematics and induced aerodynamic loading of individual vortices in vortex-dominated flows: a computation and data-driven approach
Karthik Menon, Rajat Mittal
A physics-based data-driven computational framework for the quantitative analysis of vortex kinematics and vortex-induced loads in vortex-dominated problems is presented. Such flow…
On the initiation and sustenance of flow-induced vibration of cylinders: insights from force partitioning
Karthik Menon, Rajat Mittal
The focus of this work is to dissect the physical mechanisms that drive and sustain flow-induced, transverse vibrations of cylinders. The influence of different mechanisms is quant…
The Flow Physics of COVID-19
Rajat Mittal, Rui Ni, Jung-Hee Seo
Flow physics plays a key role in nearly every facet of the COVID-19 pandemic. This includes the generation and aerosolization of virus-laden respiratory droplets from a host, its a…
Aeroelastic response of an airfoil to gusts: Prediction and control strategies from computed energy maps
Karthik Menon, Rajat Mittal
A method to predict the aeroelastic pitch response of an airfoil to gusts is presented. The prediction is based on energy maps generated by high-fidelity fluid dynamic simulations…
