 | Under direct impact from ballistic loads, acoustic waves typically propagate throughout a structural component causing damage to sensitive areas. For structures with intelligent embedded monitoring systems, such as mounted piezoelectric actuators, a direct impact between 150 200 m/s of small-caliber rounds has produced catastrophic results. This report focuses on redirecting acoustic waves using non-traditional structural configurations. The technical approach utilizes periodic and graded metamaterials (produced from auxetic cellular, lattice topology ... |

| Efforts by nongovernmental organizations, research and academic institutions, charities, and international organizations to track and monitor activities and conditions in high-risk settings provide uniquely useful indicators and warnings of possible genocide and mass atrocity (GMA). Third-party access to credible and legitimate information about conflicts that may be leading to GMA can be critical to effective U.S. efforts to meet its obligations under Responsibility to Protect (R2P). U.S. interest in the ... |

| Previous research conducted by DRDC-Toronto to evaluate watch schedule variants used on Royal Canadian Navy (RCN) submarines indicated very significant and deleterious effects of the watch system on modeled cognitive effectiveness of RCN submariners. Subsequently, DRDC-Toronto hosted an International Submarine Watch Schedule Symposium which led to a new RCN submarine watch schedule that improved modeled performance by about 30%. The RCN surface fleet is aware of this work and supported ... |

| Both the public sector and the military are working on developing drowsiness detection systems, as driver fatigue is a significant contributor to motor vehicle accidents. Individually, electroencephalography (EEG) and eye-tracking measures are tenuous indicators of driver fatigue and impairment. This project proposes to integrate multiple sensor modalities in order to improve drowsiness level assessment and driver performance prediction. There is substantial evidence supporting the correlation of alpha bursts in EEG ... |

| Background: The quantification of species-richness and species-turnover is essential to effective monitoring of ecosystems. Wetland ecosystems are particularly in need of such monitoring due to their sensitivity to rainfall, water management and other external factors that affect hydrology, soil, and species patterns. A key challenge for environmental scientists is determining the linkage between natural and human stressors, and the effect of that linkage at the species level in space and ... |

| In dolphins, natural selection has developed unihemispheric sleep where alternating hemispheres of their brain stay awake. This allows dolphins to maintain consciousness in response to respiratory demands of the ocean. Unihemispheric sleep may also allow dolphins to maintain vigilant states over long periods of time. Because of the relatively poor visibility in the ocean, dolphins use echolocation to interrogate their environment. During echolocation, dolphin produce clicks and listen to returning ... |

| Fast-paced data-to-decision systems are heavily dependent on the reliable sharing of sensor-derived information. At the same time a diverse collection of sensory information providers would want to exercise control over the information shared based on their perception of the risk of possible misuse due to sharing, and also depending on the consumer's requirements. To attain this utility vs. risk trade-off, information is subjected to varying but deliberate quality modifying transformations ... |

| We investigate the problem of identifying individual link metrics in a communications network by measuring accumulated end-to-end metrics over selected paths under the assumption that link metrics are additive (e.g., delay) and constant in the measurement duration. Based on linear algebra, we know that all link metrics can be uniquely identified when the number of linearly independent paths is equal to the number of links in the network. However, there ... |

| Emerging ad hoc networking environments, such as those currently being adopted by the defense and first response communities, call for a new generation of network monitoring capability. Current monitoring tools must either rely upon measurement protocols designed for a previous generation of systems or leverage only a subset of network devices that support some custom protocol. For certain kinds of networks, we make the case for shifting from a protocol ... |

| The destabilizing potential of recidivist insurgent activity in Iraq by former detainees poses a significant risk to Iraq and to United States interests in the region. Thousands of detainees were interned by United States (U.S.) forces in Iraq between 2003 and 2011. Despite unprecedented successes in U.S. detentions operations, early operational mistakes fostered a detainee population sensitive to recidivism that may be influenced to engage in future destabilizing activities.

| Since 1973, nearly 80% of DoD ACAT I programs have experienced cost overruns, coupled with a four-out-of-five chance of not fielding capability to the warfighter on time. With the DoD acquisition reforms of the past two decades, the probability of program success (PoPS) rate is improving. To continue improving PoPS, program management tools and techniques need to develop and become institutionalized to monitor software-intensive-based capability control, and logic development efforts. ... |
