RDRTec Inc. and The John Hopkins University Applied Physics Laboratory (JHU/APL) propose to gather data in support of the development of techniques that will enable the efficient and effective detection and tracking of Small Maritime Targets (SMT) at high altitudes. This capability will be incorporated as an upgrade to the currently funded Radar Collision Avoidance System (RACAS) under development ...

Using its Phase I program results, M4 Engineering, Inc. and Sandia National Laboratories will continue to create a unique bonded joint analysis methodology and associated software. Surrogate traction-separation models will be created that efficiently capture the behavior that occurs for real bonded joints. Mixed mode loading, including compressive normal tractions and relative displacements will b ...

To address the Navys need for a solid state fundamental mode green laser for ocean mine detection, Lumany is proposing a compact, high efficiency, diode pumped solid state, q-switched laser based on novel laser diode pumps and a unique solid state crystal with excellent with energy storage properties for high peak power, short pulsed green lasing output at 520nm from the fundamental mode. This pro ...

Digital equalizers have been the major enablers in RF communications in terms of managing component imperfections and channel impairments. Specifically, the ever increasing processing power of the dedicating computing processors has availed a steady increase in the ability of complex communication systems to deal with impairments as well as allowing higher capacities in the information transfer. O ...

IFOS proposes to develop a fiber-optic-based sensing system and a unified damage mechanism model utilizing an integrated fiber Bragg grating (FBG) sensor system for prediction of remaining useful life of rotorcraft structures. The proposed new rotorcraft damage modeling technique makes it possible to incorporate temperature and acoustic emission (AE) measurements with load tracking techniques for ...

Conduct comprehensive experimental tests using an existing microwave generated plasma igniter (M/W Igniter) that provides a continuously stabilized heat release source to suppress augmentor combustion instability or screech and to reduce the lean blowout (LBO) and light-off (LO) limits in modern/advanced or legacy augmentor flameholders. The test flow environments will include known combustion tes ...

Cascade Technologies and its collaborators from the Florida State University and Stanford University propose to develop a robust computational framework to enable geometrical optimization of complex non-axisymmetric exhaust systems with controlled accuracy and low computational cost. In this framework, Reynolds-averaged Navier-Stokes (RANS) surrogates will be constructed based on extensive databas ...

Texas Research Institute Austin, Inc. (TRI/Austin) is developing a lithium-ion battery module that will manage individual cell thermal runaways in two ways. The active management path will be to monitor the internal temperature of the cell and remove the cell from the charging/discharging circuit if anode or cathode temperatures exceed specified temperatures. Removal from the charging/discharging ...

This effort proposes to design, develop and fabricate prototype SiGe MMICs that when combined with GaN MMICs forms the basis for additional simultaneous modes and more efficiency for the C-band Radar Automatic Collision Avoidance System (RACAS). The addition of these MMICs will enable digitally controlled pulse mode interleaving and switchable and simultaneous polarizations for enhanced Coherent A ...

Humans are still unsurpassed in their ability to search for objects in visual scenes. On the other hand, object detection continues to be one of the hot areas of computer vision, and it attests both to the fundamental importance of the problem and the fact that existing state-of-the-art algorithms are still shy of performing well in practice. We propose to utilizes human vision modeling of a fovea ...
