We propose to investigate the feasibility of obtaining fast and accurate trajectories using global geopotential models representing departures from the two-body plus J2 terms. The proposed geopotential formulations and numerical integration methods rely on multi-core processors and the emerging massive parallel capabilities of Graphics Processing Units (GPUs) available to common personal computer ...

Two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. In Phase I, New Span Opto-Technology has demonstrated novel concepts of both holographic recording technique and recording material system without the use of high voltage. We have ...

ABSTRACT: A system that operates at room temperature and that could scan for concealed weapons from standoff distances of >10 m would be a tremendous asset for US military homeland security personnel worldwide. THz imaging can, potentially, be used for this application, but it requires the development of a new class of THz detectors whereby the signal to noise ratios are improved significantly. ...

The Phase II effort will be to clearly demonstrate the feasibility and build a prototype of a noncontact, high-quality holographic polarimetry system with pixel level depth and Mueller matrix information with a user-friendly interface to image and display this data. The measurements of each data product will be validated with trusted truth samples. The system will be reproducible and will have a d ...

AEDC personnel have developed and demonstrated the effectiveness of coupling a control volume model with a wind tunnel control system. The performance of the model was hampered because parameters of the model were assumed to be constant, when they are likely variables. A method for using facility data to determine functional relationships defining these parameters would allow them to vary during ...

Tensile-strained germanium tin structures will be developed for infrared emitters and detectors that are compatible with silicon fabrication processes.Optical detectors in the wavelength range of 2-5 microns will be developed by using GeSn on silicon ...

Nonlinear transmission lines offer new vistas in the generation of high power microwave wave (HPM) signals. All electromagnetic sources use an active medium to convert electrical energy to high frequency waves and ultra-wide band signals that can perform useful work. Traditional methods rely on electron beams for the active medium. Nonlinear transmission lines use nonlinear circuit elements to ...

In this STTR program, Structured Materials Industries, Inc. (SMI) and Cornell University are developing a flexible graphene film deposition system, for both research and production applications. In Phase I, our team demonstrated technical feasibility of scaling existing graphene process technology at Cornell to large wafer sizes. We demonstrated high quality graphene films by both silicon sublim ...

Improving feature extraction, event detection, and target classification in multi-sensor systems requires new mathematical methods and processing techniques. In addition, previous research and experience suggests that leveraging sensor data that has not experienced significant dimensionality reduction can preserve subtle features when processed jointly with other relevant data. However, traditiona ...
