We propose an intelligent assessment concept that will discover and reason about KSAs in multiple instruc-tional domains and settings. SoarTech will team with world-class researchers from the University of Califor-nia, Davis and the University of Memphis to research and develop TARGET: Transfer via Active Requests to Generalize Effective Training. TARGET will enhance SoarTechs assessment system DA ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

ABSTRACT: Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make use of the full aperture of the aircraft thereby maximizing achievable resolution. This sensor ...

A major challenge in MAD for submarine detection is the separation of the background magnetic noise from the magnetic field anomalies caused by a submarine. Virtual EM Inc., in partnership with the University of Michigan (UM), proposes to develop a novel electric field sensor system for measurement of the background magnetic noise by correlating the magnetic field background noise with the changin ...

Turbulent shear flows in naval applications are characterized by vastly different lengths and time scales associated with rotor tip vortices and the vortical structures shed from the ship, and additional phase from water drops and water vapor. To tackle the modeling challenges, we propose a novel methodology that combines a vorticity preserving method and a new approach to LES turbulence modeling ...

The technical objectives of this proposal are: 1) the design of high-index-contrast (HC) photonic-crystal (PC) THz, difference-frequency-generation (DFG) quantum cascade lasers (QCLs) with midinfrared pumps at 8 micron and 9 micron wavelengths; 2) design and demonstrate operation of a 4 THz DFG-QCL with the midinfrared pumps operating at 8 and 9 microns; and 3) Theoretically demonstrate the feasib ...

ABSTRACT: This project will develop and demonstrate a software package based on coupled Fokker-Planck (FP) - Fermi Kinetic Transport (FKT) models and full-wave Maxwell electromagnetic (EM) solver to accurately predict semiconductor device behavior from dc up through the mm-wave and THz frequency ranges. The FP model provides accurate non-equilibrium occupation functions for hot electrons with real ...

ABSTRACT: Analysis and Applications and Associates, Inc. (AAA) proposes to develop software that evaluates effects of the hypersonic flow environment on electro-optic/infrared optical systems and vehicles for specific hypersonic flight profiles. We propose a high fidelity definition of the near-field flow, using the latest CFD and turbulence modeling technologies, to determine the environment from ...

Computational Sciences LLC will collaborate with the Rensselaer Polytechnic Institute (RPI) to develop and validate a stand-alone computational module that naturally accounts for the effects of turbulence. Such fluctuations and transitions may be associated with compressible flows and boundary layer interactions. The module will be designed for implementation in to existing legacy codes for use in ...

We will design, fabricate, and characterize an ion microtrap equipped with an integrated in-situ cleaning capability and with integrated optical access ports. The trap will be made of optical quality fused silica. The trap design and the fabrication process will allow for future developments, such as the addition of an integrated oven, UHV-maintaining subsystem, and rapid trap exchange with interc ...
