Array imaging of localized objects in homogeneous and heterogeneous media
Anwei Chai, Miguel Moscoso, George Papanicolaou
We present a comprehensive study of the resolution and stability properties of sparse promoting optimization theories applied to narrow band array imaging of localized scatterers.…
Coherent imaging without phases
Miguel Moscoso, Alexei Novikov, George Papanicolaou
In this paper we consider narrow band, active array imaging of weak localized scatterers when only the intensities are recorded at an array with N transducers. We consider that the…
A risk analysis for a system stabilized by a central agent
Josselin Garnier, George Papanicolaou, Tzu-Wei Yang
We formulate and analyze a multi-agent model for the evolution of individual and systemic risk in which the local agents interact with each other through a central agent who, in tu…
Consensus Convergence with Stochastic Effects
Josselin Garnier, George Papanicolaou, Tzu-Wei Yang
We consider a stochastic, continuous state and time opinion model where each agent's opinion locally interacts with other agents' opinions in the system, and there is also exogenou…
Synthetic Aperture Imaging of Direction and Frequency Dependent Reflectivities
Liliana Borcea, Miguel Moscoso, George Papanicolaou +1
We introduce a synthetic aperture imaging framework that takes into consideration directional dependence of the reflectivity that is to be imaged, as well as its frequency dependen…
