ENIG, in collaboration with SRI, proposes to develop a modeling methodology with predictive and inferential capabilities to address the challenges of designing body armor to resist realistic multiple impacts from burst fire events. Our toolkit will provide an end-to-end modeling capability, grounded in the statistics of realistic impacts from small-arms fire, which would address the final material ...

This proposal will investigate body armor systems to the effects of burst fire. In Phase I, the team of researchers will investigate the spatial distribution of impacts of common burst fire capable rifles, demonstrate a statistical analysis technique, and demonstrate a ballistic model approach while applying this research to a surrogate body armor solution. The program will begin with an analysi ...

Approximately 5-6% of military injuries involve some form of major peripheral nerve injury that has little chance of spontaneous healing. Currently these injuries lead to major impairment of voluntary muscle function in the limbs and extremities, making tasks of walking, reaching, grasping, etc. very difficult or impossible for many patients. Focusing therapeutic treatments to segmental nerve in ...

There is an increasing need to understand the impacts particles emitted by both natural and human activities have on cloud properties, precipitation and climate. DOE has identified a need to improve the measurement capability of observational platforms, particularly in the Arctic region. One barrier to progress in understanding the interactions of particles and clouds and the importance of cloud c ...

The increased accessibility via remote login, along with steadily growing numbers of HPC users and projects, poses a challenging question for HPC system management: How to secure HPC systems and protect the data inside these systems? There are several challenging issues that prevent the direct deployment of existing personal computer or cloud security tools in HPC systems: 1) The overhead introduc ...

Transmission electron microscopy is one of the primary tools for biological and materials characterization and has many important research applications. However, there is an overarching need to simultaneously improve both its spatial and temporal resolutions, beyond currently available technology, to study physical processes near atomic scales. Technical Approach RadiaBeam Technologies and UCLA pr ...

As the world population increases and global GDP rises, the demand for energy is projected to increase dramatically. Fossil fuels are currently a leading energy source, approximately 50% of which is imported from foreign sources. A domestically produced, renewable energy source is needed to ensure the energy security of the United States. One source of domestic potential energy currently under- ...

Organic chemicals comprise the dominant fraction of particulates found in atmospheric aerosols, and the largest proportions of these are secondary products formed in the atmosphere from oxidation of volatile organic compounds. Often these chemical transformations result from complex pathways involving species from different sources. To understand these processes, we need to be able to trace the ...

DoD is concerned about circadian rhythm misalignment in military personnel as it is known to affect judgment, psychomotor skills, and may lead to or be triggered by Post-Traumatic Stress Disorder (PTSD). Correction or maintenance of circadian phase in soldiers participating in military night operations or planning for trans-meridian flights is also of interest. In addition, many veterans who suffe ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of
