This project will develop an augmented reality application to generate personalized formative assessment feedback as students interact with physical objects related to STEM (science, technology, engineering, and math) concepts, such as recognizing the shape of an atom. The prototype will be designed as a multi-sensory tool to support students with visual challenges. At the end of Phase I, in a res ...

SoarTech proposes DeepCounter: a system that automatically learns UAS and C-UAS behaviors across multiple tasks using DRL within a 3D simulation environment. Our system addresses several gaps in applying state of the art DRL to learn C-UAS and UAS behaviors. First, our existing DRL framework extends the state of the art to work with variable numbers of heterogenous agents. Our work in Phase I will ...

Handheld radioisotope identification instruments (RIIDs) are an important, front-line tool for passively detecting, locating, and characterizing radioactive materials and thereby helping to prevent the spread of illicit nuclear materials. Border patrol, customs, and law enforcement personnel, along with warfighters, demand an enhanced, more sensitive RIID capable of integrated gamma and neutron de ...

Chemical and biological (CB) warfare agents are a serious threat to our soldiers and national security. Different warfare agents and microbes may be delivered using solids (powders, particulates, ice crystals), hydrosols (air borne liquid droplets), or aerosols (air-born particulates). Solids, hydrosols, or aerosols can penetrate, accumulate, and transport through both porous and non-porous surfac ...

An electromagnetic pulse (EMP) attack could cause widespread outage of the commercial electric power system that could last for weeks to months. Microgrids for defense critical infrastructure (DCI) should thus be equipped to operate in islanded mode for extended periods of time using only local fuel storage and renewable energy sources. The primary difference between operating a microgrid in islan ...

While aluminum casing materials provide some enhanced performance and thermal loading to explosive ordinance, their overall effectiveness is highly limited by incomplete combustion and long residence times. In order to reduce these problems, the casing material must be designed to facilitate rapid fragmentation through either specialized casing geometries or greatly refined initial particle sizes. ...

This project investigates the possibility of intersubband optoelectronics as a general replacement for standard interband lasers and detectors when radiation hardness is a prime concern.It is argued that the majority carrier nature of the intersubband device provides intrinsic resistance to displacement-related effects that occur during high energy particle irradiation.This argument will be proven ...

Per- and Polyfluoroalkyl Substances (PF AS) have been widely used in everyday consumer products. Landfills are the final repository for the PF AS-containing products and wastes, and consequently, one of the major sources of PF AS to the environment. Elevated concentrations of PFAS in leachate have raised concerns regarding disposal of leachate. Yet, cost-effective treatment technologies for PF AS ...

Antibiotic resistant bacteria have become a major concern in discharges from hospitals, wastewater treatment plants, and agricultural runoff. A quick, inexpensive, field- deployable method of detecting antibiotic resistant bacteria in these waters is desirable. Antibiotic resistant bacteria of concern include Salmonella, Staphylococci, E. coli, Enterococci, and coliform bacteria, among others. A p ...
