(MEDE). Under the MSME, a multi-university team is charged with doing the fundamental multiscale modeling on lithium batteries, fuel cells, and electronic materials and devices. The supporting experimental work will be done at ARL. Given the substantial issues concerning the premise of bridging the scales in multiscale modeling, many challenges (and thus opportunities) exist in demonstrating verifiable success in the time frame of 5 years. Close interactions of ARL personnel with the multi-university team selected will be critical to ensure a focused and productive group effort.
BATTLEFIELD ENVIRONMENT DIVISION AND COMPUTATIONAL SCIENCES DIVISION OF THE COMPUTATIONAL AND INFORMATION SCIENCES DIRECTORATE
The Army has a unique and pressing requirement for near-Earth atmospheric understanding and characterization beyond what can be provided by other military and civilian entities. The Battlefield Environment Division (BED) has been responding to this need by addressing fundamental scientific problems and is making progress toward becoming a first-class research organization. BED’s work in the following areas involves creative combinations of theory and experimentation and of hardware and software to move toward solutions of challenging problems: turbulence propagation theory and effects, weather research and forecast model-based nowcasting for battlefield operations, systems aimed at single-particle detection for use in biohazard threat applications, and optical systems for atmospheric sensing. Continued efforts to validate underlying models and demonstrate practical applications for these and other projects are necessary and planned. Consistent, appropriate verification of the performance of mesoscale and microscale models remains a challenge to the wider meteorological numerical modeling community, and BED is still at an early stage in arriving at an assessment scheme for its various numerical prediction models.
The overall technical quality of the research conducted in the Computational Sciences Division (CSD) is improving. Some CSD projects are of very high quality. For example, the multiscale materials modeling work involves ambitious and powerful goals that build on ARL strengths. The work demonstrates a very good basic science approach that supports an important and large ARL enterprise in multiscale modeling. The division’s multiscale materials modeling program requires intensive computational capabilities. There was evidence that CSD understands that verification and validation are required not just for the models, but for the data exchanges between the models and transitions between scales.
The structure of the CSD includes a substantial facilities component that serves the high-performance computing and networking infrastructure needs of ARL, the Army, and the Department of Defense (DoD); now it also includes a growing research component focused on interdisciplinary computational science. The CSD team has made substantial progress in a very short time in articulating a research vision and realigning activities to support that vision within the research component.
Within CSD, awareness of prior extramural work continues to be uneven. To confirm this awareness and the technical quality of its work, CSD should employ the mechanisms available in academic circles—for example, peer-reviewed publication and attendance at conferences, symposia, and other professional meetings.
HUMAN RESEARCH AND ENGINEERING DIRECTORATE
Research in the Human Research and Engineering Directorate (HRED) is currently organized around eight research thrusts—sensory performance, physical and cognitive performance interaction, translational neuroscience, social-cognitive network science, human-robot interaction (HRI), human-systems integration (HSI), opportunity-driven human factors research, and simulation and training technology.
