ABSTRACT: Information is a national asset that must be protected. To make effective use of this asset, information sharing is critical between government agencies, with foreign government partners, and with the private sector. At the same time, in practice, balancing information sharing and information protection can be difficult. Tools are needed to address many challenges, including managing ...

ABSTRACT: Close integration of photonic devices with silicon complementary metal-oxide semiconductor (CMOS) electronics can yield significant performance improvements in many applications. The recent development of novel integrated structures in silicon including waveguides, resonators, and photodetectors will enable dramatic reductions in size, weight, and power for components implementing compl ...

ABSTRACT: The overall technical objective of this Phase II effort is to develop computational tools for computing response sensitivities of parametric multi-disciplinary air vehicle systems that exhibit nonlinear dynamic behavior for use in gradient-based optimization, smart sampling, uncertainty quantification, and risk assessment. To this end, the ZONA/MIT team will extend the 2-D ZEUS time-dom ...

ABSTRACT: The objective of this proposal is to develop efficient sensitivity analysis methods based on adjoint techniques for multi-disciplinary time-dependent problems. The approach is based on the discrete adjoint, which is derived and implemented on a software component basis, with the various multidisciplinary software components being linked together through a Python interface, thus preservi ...

ABSTRACT: Our objective is to develop a vision system for a micro air vehicle (MAV) or other robotic system that allows it to operate in extremely low light levels, including in zero light conditions and without reliance on GPS. We propose building two systems. The first system will operate primarily in the visible and NIR domain and utilize silicon based photoreceptor circuits. This system will ...

ABSTRACT: Physical Sciences Inc. (PSI) and the University of Tennessee Space Institute (UTSI) will develop an innovative system to measure and control the cryodeposit layer thickness that develops on cold (~20 K) surfaces in cryogenic radiometric calibration chambers. Currently removing the cryo-layer involves a lengthy process that warms the entire cryo-system to desorb the cryo-layer that incr ...

ABSTRACT: Triton Systems proposes to develop a novel computational model for complex particulate composite mixing processes and the resultant microstructures in high shear environments. Control of mixing of granular and particulate composites (e.g., particles in a polymer matrix) to achieve homogeneous mixtures is essential in many important functional material systems and applications, including ...

ABSTRACT: Underground facilities can be used by rogue governments to conceal command-and-control and to manufacture weapons of mass destruction, and are an increasingly important operational challenge to U.S. military forces. Our objective is to determine improved methods of detection essential to address this critical intelligence need. Activity below the ground causes seismic surface waves th ...
