Failures in aircraft electrical power systems can compromise the readiness, safety, and capabilities of the war-fighter. Furthermore, if the root cause for the failure cannot be quickly identified, this can lead to increased maintenance costs and potential downtime for the aircraft. In this effort, enhanced diagnostic and prognostic algorithms will be implemented in a hardware unit to minimize suc ...

Our Fused-Realities-Assessments-Modules(FRAM) enables innovative new levels and types of automated quantification strategies for combining human and system performance in real-time for fused performance monitoring and after-action-review purposes. FRAM accomplishes this by fusing output of normative models of behaviors (cognitive/procedural/team), human states (physiological/affective), system sta ...

The proposed work seeks to clearly demonstrate the advantage of the multiple-input multiple-output (MIMO) radar architecture over a similar single-input multiple-output (SIMO) or phased array system; the benefit of applying data-adaptive signal processing techniques in favor of their data-independent counterparts; and the utility of transmitting advanced probing waveforms as opposed to conventiona ...

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...

This project will develop tunable notch filter for the mitigation of co-site interference and jamming sources. The novel filter technology explored in the Phase I program has displayed excellent potential to provide wide tuning capability, low out-of-band insertion losses, deep notch depths, compact form factors and low power consumption. Furthermore, by using novel MEMS tuning membranes, high fil ...

The proposed program will develop dielectrics for dc superconducting power transmission cables that are cooled with cryogenic helium gas. The Dielectrics will be sealed again helium gas penetration and allow for an operating voltage of 12 kV in a pressure of 2 MPa at 50 K. The dielectrics will be designed for use with all helium facing components of power transmission systems based on CORC cables. ...

x-Ga2O3 has emerged as a potentially disruptive semiconductor with a predicted breakdown field of ~8 MV/cm which is more than twice the breakdown field for the incumbent wide bandgap semiconductors GaN and SiC. The availability of -Ga2O3 bulk substrates sets this material apart from other wide bandgap materials for power electronic applications. However, the challenge is to find suitable epitaxial ...

Augmented reality (AR) offers the ability to enhance existing combat medic training by including perceptual cues and adaptive training elements to traditional simulation-based training using manikins. Unveil has developed a training system called the Macrocognitive AR Trainer (MART). MART is designed to foster the development of macrocognitive skills (e.g., sensemaking, assessment skills, mental m ...
