Physical Sciences Inc. (PSI) and the research group of Professor Richard Osgood at Columbia University propose to develop a compact optical transceiver based on devices fabricated on a complementary metal-oxide semiconductor (CMOS) platform. The recent development of novel integrated structures in silicon including waveguides, resonators, and photodetectors will enable dramatic reductions in size, ...

LongShortWay Inc. and Northeastern University propose a family of feature reduction and ensemble classifier methods based on Principal Component and Dynamic Logic feature clustering algorithms. New methods combine feature clustering with non-linear feature reduction via manifold learning, and bagging, boosting, and stacking ensemble algorithms.

ABSTRACT: Busek Co. Inc. and Massachusetts Institute of Technology (MIT) propose to explore the physical limits of ionic liquid propulsion via development of new theory to explain effects of close packing emission density and to predict performance limits. The research is motivated by observations and tests demonstrating that emission from 2-dimensional porous surfaces yields order of magnitude g ...

ABSTRACT: LongShortWay Inc, Boston University, and Applied Communication Sciences propose to develop a dynamic multi-sensor learning system that can adaptively detect target types and activities and schedule sensors to optimize the detection rate BENEFIT: Improved detection rate, increase field of view

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: 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: 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 ...

ABSTRACT: Busek proposes, with the MIT Space Propulsion Lab, to leverage successful Phase I proof-of-concept results to develop and deliver a 1mN, micro-fabricated electrospray thruster that features variable Isp and bi-polar operation. The thruster achieves variable Isp at no power penalty by innovative use of a deceleration grid, and operating in purely ionic mode so as to overcome many of the ...

ABSTRACT: Composite materials are increasingly adopted into Aerospace application due to their superior specific strength/stiffness, resistance to fatigue and ability to reduce part-count. Furthermore, it has been demonstrated that by introducing carbon nanotubes (CNTs), multi-functional capabilities can be achieved by virtue of their high conductivity and piezoresistive nature. During the prop ...

ABSTRACT: In collaboration with Sandia National Laboratory, Physical Sciences Inc (PSI) proposes to design, develop, and demonstrate a Frequency Agile Terahertz Sensor (FATS) for trace explosives residue detection. The critical frequency agile terahertz (THz) detector is based on an electronically tunable plasmonic grating-gate technology developed by our collaborators at Sandia. The Phase I ...
