- We consider a secret sharing model where a dealer shares a secret with several participants through a Gaussian broadcast channel such that predefined subsets of participants can reconstruct the secret and all other subsets of participants cannot learn any information about the secret.

- This work carries out collaborative theoretical, experimental and numerical investigations of flow-acoustic resonant interactions in transitional airfoils which are responsible for sudden appearance of prominent acoustic tones and unsteady aerodynamic fluctuations in low-Reynolds-number airfoils.

- This research focuses on sUAS MAC likelihood analysis with general aviation (GA) and commercial aircraft. Because severity research varies based on where a collision occurred on a manned aircraft, this likelihood research will not only look at the probability of a MAC, but also the likelihood of colliding with different parts of a manned aircraft.

This NSF funded project seeks to develop a novel software that will provide a variety of pedestrian dynamics models, infection spread models, as well as data so that scientists can analyze the effect of different mechanisms on the spread of directly transmitted diseases in crowded areas. The initial focus of this project is on air travel. However, the software can be extended to a broader scope of applications in movement analysis and epidemiology, such as in theme parks and sports venues. Development of the proposed software will involve several innovations. It will include a novel phylogeography model that links fine-scale human movement data with virus genetic information to more accurately model geographic diffusion of viruses. New models for pedestrian movement will enable modeling of complex human movement patterns. A recommendation system for the choice of pedestrian dynamics models and a domain specific language for the input of policies and human behaviors will enhance usability by researchers in diverse fields. Community building initiatives will catalyze inter-disciplinary research to ensures the long-term sustainability of the project through a critical mass of contributors and users.
- The basic goal of the research is to understand impacts to aviation stakeholders of the National Airspace System (NAS) due to space launch activities. The focus of the research is to study impacts to general aviation (GA), particularly with respect to airports and airport users, near and around Cape Canaveral, FL. Further, several avenues will be assessed to determine what aspects of GA are impacted, where, when, how, and why. Data will be collected and analyzed in alternate methods other than the originally-proposed simulation and modeling. As an aside, per FAA input and following review of extant literature, impacts to GA have not been adequately researched. Until recently, the industry and the FAA have largely focused on impacts to airlines (Tinoco, Eudy, Cannon 2020). As a result, we believe this effort will lead to interesting outcomes and fill a much-needed gap in the literature.

The HSP-X1 is a next-generation hybrid spaceplane designed to operate as a reusable single-stage-to-orbit vehicle. This means it takes off like a conventional airplane, reaches orbit without additional stages, and returns by landing on a runway—all using a single integrated vehicle. Its primary mission is to transport payloads on the order of tens of tons to low Earth orbit (LEO) more efficiently and rapidly than traditional launch systems.

Merriam-Webster Dictionary (2020) defines a spaceport as “an installation for testing and launching spacecraft,” but spaceports are so much more than a slab or runway and represent an essential component of the entire space industry ecosystem (e.g. Tinoco, et al 2020). Without spaceports, there is no spaceflight. There are no astronauts. There are no satellites. There is no International Space Station. And there is no Artemis and no expedition to Mars.
A review of online learning resources for children, parents, and teachers reveals instructions and learning tools for wide range of topics including rockets, spacecraft, satellites, planetary and lunar land vehicles; propulsion systems; planets, moons, and solar systems; spacesuits, among others. Yet, no resources were found on spaceports and spaceport infrastructure, the very foundation of spaceflight.
The intent of this effort is to build an education curriculum on spaceports that enlightens children, teachers, and families on spaceports and the infrastructure needed to support the safe integration, launch, and return of various vehicles, crew, and payloads. Many children believe that space is exclusively the domain of astronauts, engineers, or scientists (e.g., The LEGO Group 2019). Educators and parents are often of the same mindset. But space is for everyone and the careers associated with the space economy are wide and varied. Spaceports are just one domain where many individuals contribute to the success of a space program or initiative, each a valuable member of this unique sector. The more our younger populations learn of the different areas of the space ecosystem and the associated types of jobs, the better we all will be in building and sustaining a space economy fortified by a diverse workforce. Initially, the primary beneficiaries of this effort will be local school children and teachers in the state of Florida, particularly in Volusia County and other geographic areas of the Space Coast. Our hope is to engage economically disadvantages schools (with and without STEM programs) for a pilot study, allowing for a wider audience of interests and backgrounds. Our proposed effort has garnered the encouragement of Space Florida and resource support from Space Foundation and Volusia County Public Schools (VCPS) teachers.
