MARK Resources Inc has developed processing algorithms to classify small ships based on 3-d scatterer positions extracted from ISAR data. This processing relies on measuring range-Doppler positions of selected scatterers over selected imaging intervals. Extending the processing to small boats entails overcoming degraded resolution due to larger and rougher boat motions, smaller physical separation ...

The technical objectives of this proposal are: 1) the design of 3.0-3.5 micron-emitting quantum cascade laser (QCL) structures grown on metamorphic-buffer-layer (MBL) substrates; 2) the realization of electroluminescent QCL structures on MBLs with emission in the 3.0-3.5-micron wavelength range. Novel tapered active-region (TA) QCLs will be designed to substantially suppress carrier leakage out of ...

M4 Engineering, Inc. and Sandia National Laboratories propose to create a unique bonded joint analysis and design software tool. 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 be captured and used in an extended cohesive zone ele ...

Adhesive bonds are increasingly finding their applications in aerospace and automotive structures. The adhesive bonding gets rid of fasteners, thus reducing stress concentrations and damage initiation sites. In addition, elimination of fasteners results in significant weight savings. In order to use adhesive bonding with confidence and certify integrity of bonded structures, certain issues regardi ...

Gener8, Columbia University and Lockheed Martin will team to develop a high-speed electronically tunable wavelength filter. Columbia University has developed a method of fabricating thin-films of lithium-niobate called Crystal Ion Slicing (CIS). These thin films enable new electro-optical devices to be designed with order-of-magnitude improvements in electro-optical performance. Two design concpet ...

Aurrion will demonstrate a high-speed, electronically tunable wavelength filter using integrated silicon photonics. This tunable filter will enable selection of any channel in a Wavelength Division Multiplexing (WDM) network across the full ITU C-band in less than 1 microsecond and be usable in an operation range of -40 to +100degreesC

Aerospace structures are subject to dynamic loading. In particular, gearbox components experience continuous cyclic loading, wear and eventually develop fatigue cracks. As opposed to most other aircraft components, gearbox components are non-redundant, so a failure can have catastrophic consequences. Gearbox members are typically magnesium, aluminum or high-strength steel that exhibit high fractur ...

A scheme to implement logic gates based on nonlinear dynamic systems is proposed. This approach allows for the realization of a powerful yet flexible computing architecture. For the Phase I effort, AshRem Technologies in conjunction with California State University, Los Angeles, will analyze and the implement in hardware a flexible logic gate architecture that can be developed further to yield a r ...

The Navy is looking for a novel way to"test the functionality automatically of all the die on a wafer before it is diced to find the working die and then to mount the"known-good"die into a larger circuit in such a way that repair to the functionality of the whole can be accomplished by replacing the part, not the whole."The enabling technology is a reworkable adhesive with a combination of propert ...

The proposed work will focus on combined signal processing and acoustic modeling that will ultimately enable high-accuracy navigation under the Arctic ice at ranges up to and including basin scale. This combined approach is required because as the source-vehicle range increases, the bandwidth of the signals decrease because the carrier frequency must be reduced to enable long-distance communicatio ...
