In order to better understand community resilience following a disaster, a multi-disciplinary research team from the Center of Excellence (CoE) for Risk-Based...
Physical-layer analysis on millimeter-wave systems to date have used channels models reduced from measurements in static environments. This is because most...
In this work we show that powers of two multiples of the sampling period are the optimal set of averaging period Allan variance (AVAR) calculations for...
In the 3.5 GHz Citizens Broadband Radio Service (CBRS), 100 MHz of spectrum will be dynamically shared between commercial users and federal incumbents. Dynamic...
The Fifth Generation (5G) mobile broadband standards make a fundamental shift in cryptography. Prior generations based their security and privacy principally on...
The terrestrial biosphere is a crucial sink for anthropogenic emissions of carbon to the atmosphere, but is also the source of the largest uncertainties in...
Hyperspectral imaging is an innovative and exciting technology that holds incredible diagnostic, scientific and categorization power. Current industry...
