DTRA’s mission requires finding the match between the research and definition of explosive’s formulation and warhead performance properties and the defining of the expected explosive effects to defeat target structures (e.g., produce fragmentation, perform some chemical, biological defeats) which are different target effects than “simply blowing things up” (e.g., fragmentation).  Even in ...

A significant performance gap exists between the theoretical number of Floating Point Operations (FLOPS) that an HPC machine is capable of sustaining and the number of FLOPS realized by real-world HPC software. One of the principal reasons for this gap is the parasitic work that computational processes must do to communicate with one another. It has been shown that this communication work can be s ...

History Maker VR is a playful virtual reality (VR) content-creation tool that allows students to embody historical characters in immersive settings, record performances featuring those characters, and share their performance files to demonstrate material mastery. History Maker VR is designed to scaffold creative storytelling, and to encourage embodied learning and for students to take pride in con ...

During the Phase I effort, Semandex Networks and its team developed a prototype capability to detect trends in research publications by automatically identifying emerging concepts within the data. The implemented capability provides insights into past and

A generalized network topology-aware algorithm has been developed that efficiently maps structured and unstructured domains onto available nodes to minimize MPI message passing costs. The methodology utilizes sub-domain inter-dependency information, readily available from standard domain decomposition codes, along with a simulated annealing optimization technique to automatically assign sub-blocks ...

SuperChemVR is a room-scale VR lab and learning game for high school chemistry students. While wearing a VR headset, students will be immersed in a simulated chemistry 3D-environment where they will be challenged to acquire basic lab and safety skills. Through actual, accurate measurement and experimentation, students will improve their understanding of chemistry practices as they learn using scie ...

Combustion Research and Flow Technology, Inc. (CRAFT Tech) and the University of Illinois at Urbana-Champaign (UIUC) have teamed up to provide DTRA with an innovative approach to develop new combined effects explosives (CEX) formulations. CEX represent a class of recently-developed aluminized explosives seeking to provide the performance of both (i) high-energy explosives and (ii) high-blast explo ...

Video Demonstration of the Phase I Prototype: http://youtu.be/vS0XzzPl3iU Purpose: This project will develop and test Happy Atoms, a physical modeling set and an interactive iPad app for use in high school chemistry classrooms. Happy Atoms is designed to facilitate student learning of atomic modeling, a difficult topic for chemistry high school students to master. Standard instructional practice ...

DTRA and other DoD agencies are currently seeking earth penetrators with higher efficiency for reaching deeply buried targets. Current penetrator materials and designs suffer from high levels of frictional drag, unbalanced resistance due to lateral forces and localized melting of the warhead leading to shape change and further instability. General Sciences, Inc. (GSI) has developed a method for en ...

There is an urgent need to procure for our military forces on the ground in Iraq and in other locations technology and equipment which provide the capability to effectively and immediately detect, assess, and defend against the threat from Improvised Explosive Devices (IEDs). It is believed that this same threat, applied to Weapons of Mass Destruction (WMD) dispersal, could also increasingly beco ...
