In prior research and development, the team developed AlphaBear, a mobile gaming app where students are challenged to spell words which are then used to create humorous sentences. This project will develop and test a prototype for use specifically by English Learners. The prototype will formatively assess students' vocabulary, adjust gameplay to the skill levels of individual students, and provide ...

DTRA is faced with the challenge of extracting and effectively utilizing information from a very large and diverse set of natural language and structured data sources. Current methods often lack contextualization and are generally noisy, shallow, patchy, and overly low-level. We will develop a unifying, general, and elegant solution to address this challenge, based on the overall Textual Rulelog a ...

The proposed ultra-fast shutter achieves all design requirements for hypervelocity debris mitigation in the EUV cold x-ray Z-machine experiment using a high reliability magneforming shutter which has been field tested hundreds of times under conditions very similar to the Z-pinch machine. The proposed device is based upon the electromagnetic hypervelocity debris mitigation shutter put into operati ...

This program will combine Silicon Technologies analog automation technology ADONIS with EBDW technology.This combination will reduce design times and costs for Analog Trusted circuits and will facilitate reuse of obsolete, radiation-hardened, precision analog components. Originally funded by the DARPA GRATES program, ADONIS demonstrated that with analog specific modifications, ADONIS Straight Line ...

We propose the development new kind of high resolution tunable spatial heterodyne spectrometer for nuclear forensics. Preliminary results have shown that this spatial heterodyne spectrometer can be made compact without sacrificing its high resolving power for isotopic attribution of nuclear materials. Thus, the spatial heterodyne spectrometer will be able to provide the origins of nuclear material ...

The Defense Threat Reduction Agency (DTRA) recognizes the need for efficient low power high bandwidth radiation hard optoelectronics for optical intereconnects; i.e. electrical-to-optical (E/O) conversion, optical-to-electrical (O/E) conversion, and low loss optical interconnects are imperative for photonic solutions to be competitive with conventional military RF components.For the development of ...

Radioisotopes can be identified by the emission of neutrons & gammas having characteristic energies.Most hand-held radioisotope identification instruments, however, are gamma-ray centered designs that optionally include neutron detectors of limited sensitivity. Passive measurements of gamma-ray signatures can easily be compromised by shielding a source. Photogenics has developed a neutron spectrom ...

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

The Defense Threat Reduction Agency (DTRA) requires microelectronics for itself and other DoD agencies that can operate reliably in the harsh environment of space. This Phase II Small Business Innovation Research (SBIR) proposal for DTRA extends the work

Recent reports assert that the education system of the United States is failing to produce enough mathematically skilled workers necessary for the country to remain globally competitive. A key problem in the current system, as reported by the National Mathematics Advisory Panel, is that students are not learning the foundational math skills they need during the elementary school years. This projec ...
