Controller Synthesis for Omega-Regular and Steady-State Specifications
Alvaro Velasquez, Ismail Alkhouri, Andre Beckus +2
Given a Markov decision process (MDP) and a linear-time (-regular or LTL) specification, the controller synthesis problem aims to compute the optimal policy that satisfies the s…
Sketch-based community detection in evolving networks
Andre Beckus, George K. Atia
We consider an approach for community detection in time-varying networks. At its core, this approach maintains a small sketch graph to capture the essential community structure fou…
Multi-modal Non-line-of-sight Passive Imaging
Andre Beckus, Alexandru Tamasan, George K. Atia
We consider the non-line-of-sight (NLOS) imaging of an object using the light reflected off a diffusive wall. The wall scatters incident light such that a lens is no longer useful…
Scalable and Robust Community Detection with Randomized Sketching
Mostafa Rahmani, Andre Beckus, Adel Karimian +1
This article explores and analyzes the unsupervised clustering of large partially observed graphs. We propose a scalable and provable randomized framework for clustering graphs gen…
On the inverse problem of source reconstruction from coherence measurements
Andre Beckus, Alexandru Tamasan, Aristide Dogariu +2
We consider an inverse source problem for partially coherent light propagating in the Fresnel regime. The data is the coherence of the field measured away from the source. The reco…
Spatial coherence of fields from generalized sources in the Fresnel regime
Andre Beckus, Alexandru Tamasan, Aristide Dogariu +2
Analytic expressions of the spatial coherence of partially coherent fields propagating in the Fresnel regime in all but the simplest of scenarios are largely lacking and calculatio…
Incoherent lensless imaging via coherency back-propagation
Ahmed El-Halawany, Andre Beckus, H. Esat Kondakci +4
The two-point complex coherence function constitutes a complete representation for scalar quasi-monochromatic optical fields. Exploiting dynamically reconfigurable slits implemente…
Coherence measurements of scattered incoherent light for lensless identification of an object's location and size
H. Esat Kondakci, Andre Beckus, Ahmed El Halawany +3
In absence of a lens to form an image, incoherent or partially coherent light scattering off an obstructive or reflective object forms a broad intensity distribution in the far fie…
