Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop ZnO based light emitter with light emission wavelengths ranging from UV to IT. On successful completion of the proposed effort, the market place will have a unified device structure based ZnO that emits light from UV to IR. The proposed work will be accomplished by the researchers from Cermet and Georgia Institut ...

Self-healing composites and adhesives would alleviate longstanding problems in aerospace structures associated with multiple types of damage mechanisms such as mechanical/thermal fatigue, microcracking, and debonding. A composite cryogenic tank based on self-healing technology would prevent leakage by sealing microcracks throughout the lifetime of the tank and enable the use of composites in this ...

Accurate projection of costs remains an intractable problem in the defense industry despite more than a decade of focus on affordability. The impact to DoD acquisition programs, from cost escalation and the cost of countering capability shortfalls, runs to billions of dollars annually. The objective of this proposal is to develop and demonstrate an ontology-based framework for requirements-based ...

Electromagnetic propulsion using compact toroidal plasmas is ideal for high-thrust, high-Isp missions since velocities and densities are not space charge limited, the self-field structure does not suffer magnetic detachment problems and the inductive electrode-less nature has superior lifetime. This STTR builds on a long history of research by integrating an annular helicon source with a conical ...

We propose to examine the necessary ingredients for the development of marketable codes which will: model the morphology of heterogeneous propellants (a packing code); calculate the thermal and mechancial properties of such a morphology or pack; simulate the combustion of the pack; predict the statistics of aluminum agglomeration on the burning pack surface; simulate the flight of these agglomera ...

In this proposal we exploit the remote sensing attributes of ultrasound to measure temperature, transient temperature and heat flux in liquid rocket combustion chambers. In previous work, we have demonstrated the capability to measure the local temperature at the inner surface of large caliber Navy guns using sensors attached to the external gun barrel surface (2.5” from the measurement point). ...

The rapid increase in the use of the Internet in many aspects of our lives has led to an explosive growth in the spread of malware such as computer worms, viruses, and trojans. Security tools typically examine software for the presence of malware either by looking for specific byte signatures, or (more recently) by analyzing the candidate binary’s internal logic. However, it is surprisingly easy ...

PRA proposes to team with JPL to design the Total Atmospheric Effects Mitigation (TAEM) System to include both ionospheric and tropospheric mitigation. This concept builds on PRA’s innovative measurement technologies originally developed for the ETEC System and the ionospheric electron density modeling capability of JPL’s Global Assimilative Ionospheric Model (GAIM). The proposed TAEM Measurem ...

The innovative use of variational methods to dynamically segment scenes, which leads to a fast, natural approach to estimating the location of unknown 3-D obstacles is proposed. The previously developed algorithm has been shown in simulation to be suitable for real-time processing in flight using current generation processors, and to be robust in the presence of transient sensor data, distortion, ...

PRA proposes to develop a wideband adaptive digital beamforming solution to autonomously cancel multiple jammers at various locations, bandwidths, and center frequencies. The wide waveform bandwidths desired for fine range resolution in current and future phased-array systems impact the performance of adaptive cancellation algorithms due to the effects of wideband jammer dispersion, antenna archi ...
