LongShortWay Inc. and Northeastern University propose a family of feature reduction and ensemble classifier methods based on Principal Component and Dynamic Logic feature clustering algorithms. New methods combine feature clustering with non-linear feature reduction via manifold learning, and bagging, boosting, and stacking ensemble algorithms.

Rechargeable lithium ion battery systems can provide power throughout the aircraft, including engine or Auxiliary Power Unit (APU) starting, avionics, emergency, and other systems. Because of their high specific energy/power and potential thermal instability, they can present hazards if improperly designed, tested, handled, or stored. To address the thermal safety issue of Li-ion batteries, EIC La ...

SI2 Technologies, Inc. (SI2) proposes to accelerate development of printed, high-efficiency phased arrays operating at Navy-relevant frequencies. The proposed development effort will include optimization of the array printing techniques from Phase I to meet the Navys phased array performance goals. The printed arrays will incorporate both printed radiating elements and an innovative printed packag ...

Existing machine perception systems are too inflexible, and are not robust enough to environmental uncertainty. In existing systems, perception components are statically (and manually) configured to process sensor data. The parameters of components in such a system are also statically tuned to operate optimally under very specific conditions. Information flow in such systems is bottom up, and gene ...

Organized groups are become increasingly adept at using social media to influence public discourse. The fast pace and global reach of social media allow groups for form and mobilize in minutes and dissolve as rapidly as they appeared. In Phase I, we 1)

Physical Sciences Inc. (PSI) proposes to design, develop, and demonstrate a portable, non-invasive, real-time sensor to assess the chemical and physical health of solid rocket motors as a function of age without affecting the motors integrity nor having direct contact with the propellant. In Phase II, a sensor to monitor specific gas species that are markers of the chemical and mechanical aging pr ...

SI2 Technologies, Inc. (SI2) and Drexel University propose to develop printed, flexible, high-performance ultracapacitors to meet the Armys need for lightweight energy storage. SI2 will leverage its demonstrated expertise in ink jet printing and Drexels expertise with carbon nanoparticle synthesis. SI2 has considerable experience in the roll-to-roll deposition of conductive ink patterns. These ...

This DARPA STTR Phase II project is focused on novel voltage-tunable multiferroic heterostructures and components. Deliverables include: (1) liquid-phase epitaxial growth ferrite/ferroelectric heterostructures with strong magnetoelectric coupling; (2) voltage-tunable multiferroic inductors and transformers with large tunable inductance range of 2/1 and high quality factor > 20 within UHF (0.3GHz ~ ...

"HgCdTe is the material of choice for high performance infrared red focal plane arrays (IRFPA) used in militarys night vision systems. One of the major problems IRFPA manufacturers face is the ineffective passivation of the highly reticulated HgCdTe detector surfaces, which results in poor performance. Furthermore, newly evolved FPA technology requires the creation of much challenging high-aspect ...

Antimicrobial treatment of military textile systems is intended to provide enhanced protection to the Warfighter in the field by preventing colonization of harmful bacteria that cause problems such as odor, dermatitis, impetigo, cellulitis, and other skin irritations. Current treatments can impart antimicrobial functionality to textiles; however, they all possess broad-spectrum antimicrobial activ ...
