Abstract: We consider a damped linear hyperbolic system modeling the propagation of pressure waves in a network of pipes. Well-posedness is established via semi-group theory and the existence of a unique steady state is proven in… read more here.

DOI: 10.1016/j.oceaneng.2020.108478
Abstract: Abstract Liquid sloshing in square or nearly square-base tanks becomes more complex due to the emergence of three dimensional waves around resonance. Because of symmetrical base in a square tank, two predominant sloshing modes (along… read more here.

DOI: 10.1103/physrevx.10.021043
Abstract: An extension to wave turbulence theory shows that in a system of nonlinear waves, correlations among the waves arise, causing ``ghost'' excitations that lead to coherent structures in physical space. read more here.

DOI: 10.1109/mcom.2018.1701050
Abstract: Although mmWave systems promise to offer larger bandwidth and unprecedented peak data rates, their practical implementation faces several hardware challenges compared to sub-6 GHz communication systems. These hardware constraints can seriously undermine the performance and… read more here.
