Staggered Scheduling of Sensor Estimation and Fusion for Tracking Over Long-Haul Links

Networked sensing can be found in a multitude of real-world applications. We focus on the communication-and computation-constrained long-haul sensor networks, where sensors are remotely deployed over...

Performance Models for Split-execution Computing Systems

Split-execution computing leverages the capabilities of multiple computational models to solve problems, but splitting program execution across different computational models incurs costs associated...

Discrimination of correlated and entangling quantum channels with selective process tomography

The accurate and reliable characterization of quantum dynamical processes underlies efforts to validate quantum technologies, where discrimination between competing models of observed behaviors...
