A Microscopic derivation of nonlinear fluctuating hydrodynamics by Abhishek Dhar

Hydrodynamics considers a coarse-grained description of a system where one looks at the evolution of the conserved fields which evolve slowly in time. The conserved fields constitute a macrostate of the system. There are a large number of internal degrees of freedom corresponding to a give

Wavelets: a mathematical microscope

Wavelet transform is an invaluable tool in signal processing, which has applications in a variety of fields - from hydrodynamics to neuroscience. This revolutionary method allows us to uncover structures, which are present in the signal but are hidden behind the noise. The key feature of w

AWESOME Brownian motion (with explanation)!

Brownian motion is the random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid. This pattern of motion typically alternates random fluctuations in a particle's position inside a fluid subdomain with a relocation to anoth

PDE FIND

We propose a sparse regression method capable of discovering the governing partial differential equation(s) of a given system by time series measurements in the spatial domain. The regression framework relies on sparsity promoting techniques to select the nonlinear and partial derivative
