Integrated Communication and Environmental Sensing for Safety-Critical Autonomous Systems
  • PI Thomas Yang

    PI Siyao Li

  • Current communication networks with transmitter/receiver nodes can provide large-scale area coverage and robust interconnection between nodes. This allows for the seamless integration of sensing functions into the existing communication framework, paving the way for Integrated Communication and Sensing (ICAS). Unlike previous generations that treated communication and sensing separately, ICAS eliminates the need for additional hardware, extra transmit power, or dedicated frequency bands, by enabling communication signals to support data transmission and environmental sensing simultaneously. This convergence makes ICAS a key feature of six-generation (6G) communication and enables advanced applications, including Unmanned Aerial Vehicle (UAV) missions, autonomous driving, surveillance, and smart cities, to be powered by a single transmitted signal.

    This project aims to develop a novel ICAS framework tailored specifically for autonomous systems operating in safety-critical environments. The primary focus is enabling environment sensing by systematically analyzing the received information-carrying communication signals, through line-of-sight and/or reflected and scattered paths.

Integrating Expanded and Non-Segregated UAS Operations into the NAS: Impact on Traffic Trends and Safety
  • CO-I Dothang Truong

    CO-I Ryan Wallace

  • This research led by Richard Stansbury (PI) will provide further insight into the safe integration of sUAS through the forecasting of expanded and non-segregated sUAS operations. The ASSURE research team will collect data to inform the FAA on risk-based methodologies to develop and apply safety rules, regulations, and revised Safety Management System (SMS) protocols based on forecasted UAS operational needs and performance characteristics.
Integration of Small Aircraft Transportation Systems (SATS) into General Aviation
  • PI Massoud Bazargan

  • Conducted operational and simulation approaches to identify potential bottlenecks and examine future expansion strategies for airports by integrating SATS with GA.
Integration of the Emerging Space Ecosystem into the National Airspace System (NAS): Simulation and Analysis of Impacts and Solutions, NASA Florida Space Grant Consortium
  • CO-I Maxwell Cannon

    CO-I Noah Eudy

  • Currently, there is limited, but ongoing, simulation research on the integration of space operations into the NAS that focuses on impacts to other constituents and in finding solutions (cf, Tinoco, et al., 2019; Colvin & Alonso, 2015). Particularly, academic research based on modeling and simulation is quite minimal.  Thus, the first objective of this research was to continue our current efforts and develop additional simulation models to analyze the potential impacts of launch and re-entry activities on key NAS stakeholder operations, particularly those of airlines, but also general aviation. NASA KSC/Cape Canaveral Air Force Station (CCAFS) clearly play a critical role in both the state of Florida and in our nation’s space ecosystem. As such, our area of interest was defined as Cape Canaveral, Florida.  We built on our previous simulation research that centered on horizonal take-off and landing of Concept Z reusable launch vehicles (RLV) at Cecil Air and Space Port in Jacksonville, FL (cf, Tinoco et al (2019); Tinoco et al, pending) and our understanding of air traffic routes on the heavily traveled Eastern Seaboard. 

Intelligent signal processing for secure mobile wireless communications with spectrum and energy efficiency
  • PI Thomas Yang

  • In modern wireless communications, scenarios often arise in which the receiver is required to perform detection of multi-user transmissions on the same channel or suppress co-channel interferers. In these scenarios, signal separation techniques based on statistical properties can be highly effective.

  • This project investigates a novel cylinder design inspired from the Harbor Seal whisker, with the goal of reducing coolant pumping power requirements while maintaining heat transfer rates in pin-fin arrays. 
Iranian Proxy Groups in Iraq, Syria, and Yemen A Comparative Analysis
  • CO-I Hugh Sadri

  •  After the fall of Saddam Hussein, Tehran’s leaders took advantage of Baghdad’s weak position and put many Iraqi power centers and local groups under their influence using a variety of soft to hard power instruments. After the withdrawal of coalition forces from the region in 2011 and through its proxy networks, Tehran gained a solid foothold in Iraq and Syria under the guise of helping Baghdad and Damascus fight the Islamic State. Likewise, Iranian proxy groups have backed Houthi rebels in Yemen fighting a regime dependent on Saudi Arabia for survival. Our primary research question is: How does Iran develop, employ, and sustain proxy organizations in Iraq, Syria, and Yemen, and what vulnerabilities does its regional strategy face as a result? Our objective is to analyze the role of Iranian influence in its proxy organizations across the Middle East.
