Current research initiataives, including DoD IHPTET and HyTech, DOE ATS, and commercial development, are agressively pursuing significant improvements in combustor performance Optimization typically results in operating regimes for which combustionstability is difficult to maintain. This proposed program continues the novel combustion control and optimization concepts with flexible dual-use appl ...

Machine learning offers an automated approach for deriving and maintaining the mappings necessary to link records across databases. The approach we propose here, if successful, will significantly advance this technology. Previous work in this area haslargely ignored the fact that each source typically has uniform conventions for representing data. By taking this into account, we can to a better ...

The objective of this program is to develop and make ready for commercial production a novel pump design utilizing piezoelectric pumping elements combined with fast acting non mechanical active valves and a miniature digital controller. The piezoelectricactuator is an available building block that has a proven track record, surviving 3x109 cycles in diesel fuel injectors. Available conventional va ...

The present text proposes development of a new approach for the numerical evaluation of high-frequency electromagnetic scattering for structures of interest to DoD. This approach, which relies on high-order high-frequency integral asymptotics, is entirelyrigorous: it should account fully for all scatterer complexities and all electromagnetic effects - including multiple-scattering, diffraction, ca ...

Successful application of pulsed detonation wave engine for rocket propulsion bringswith it reduced engine weight, precise control over impulse, ability to operate in acontinuous or intermittent mode and ease of maintenance. The proposed effort addressesthe critical issues in the development of pulsed detonation wave engines for rocketpropulsion including the use of liquid fuel, valve-less operat ...

Our objective is to construct a new solution procedure for high frequency electromagnetic scattering and propagation problems, and to initiate building and validation of a new 3D high frequency Maxwell equations solver. The proposed method will constitutean extension of a recent asymptotic formulation of the electromagnetic integral equations for high frequency scatttering and radiation problem. ...

"This proposal is focused on enhancing and applying the trajectory generationalgorithms originally developed at Caltech to a small free-flight unmannedAero Utility Vehicle (AUV) that is under development with private funding.Our trajectory generation algorithms are based on a combination of nonlinearand optimal control theory, spline theory, and sequential quadraticprogramming. Furthermore, the a ...

"This proposed research is to develop an in-situ formation of nanoparticles coated with a atomic layer controlled coating. A novel superparamagnetic particles with orders of higher magnetic moment than current market available magnetic particles and beadswill be developed for labeling used in biology and biotechnology, especially for high sensitive portable biosensor.The long-term goal of propose ...

"Fundamental defense applications ranging from communications to remote sensing systems exploit the information content of acoustic electromagnetic signals and waves. In practice, both intentional and unintentional nonlinear interactions play significantperformance determining roles in the systems responsible for generation, transmission, reception, processing, and analysis of the signals.Analyti ...

"Integrating and querying multiple databases, web sites, or document repositories is difficult, in part because information sources often use different data formats and terminology when referring to the same entities. Machine learning offers an automatedapproach for deriving and maintaining the entity mappings necessary to link records across information sources. The approach we propose here, if ...
