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 ...

This STTR Phase II program will create novel devices and system designs, expanding upon the microring resonator based silicon WDM modulator designs and system concepts developed during Phase I. The focus will be on linear transmitters and analog fiberoptic systems, used to transmit and transform analog signals, based on the Linearized - Ring Assisted Mach Zehnder Interferometer (L-RAMZI) modulator ...

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)

ABSTRACT: Underground facilities can be used by rogue governments to conceal command-and-control and to manufacture weapons of mass destruction, and are an increasingly important operational challenge to U.S. military forces. Our objective is to determine improved methods of detection essential to address this critical intelligence need. Activity below the ground causes seismic surface waves th ...

We propose to develop a toolkit and environment for social media visualization, exploiting scientifically grounded design principles embodied in visual thinking design patterns (VTDPs). Much like software design patterns, VTDPs are reusable blueprints for design of new interactive visualizations: they describe the steps in the visual thinking process that capture operations occurring in a computer ...

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...

In Phase I MER demonstrated the superior performance and power-to-weight ratios of the VS-Rotary engine. In Phase II MER will team with the University of Arizona who will provide engine modeling, simulation, and analysis along with advanced precision machining and fabrication. MER will also team with NCE of Tucson to provide test and systems integration development of the engine to the applicatio ...

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 ...

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 ...

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 ~ ...
