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: The U.S. Air Force has a need to develop a new class of advanced, wide field of view (WFOV) imaging sensors that sample the radiation field in multiple modes: spectral, temporal, polarization, and detailed object shape. These multimodal sensors are to be deployed on high altitude drones to enhance their intelligence, surveillance, and reconnaissance (ISR) capabilities. Smaller versions o ...

SixPoint Materials will create low-cost, high-quality vertical gallium nitride (GaN) substrates using a multi-phase production approach that employs both hydride vapor phase epitaxy (HVPE) technology and ammonothermal growth techniques to lower costs and maintain crystal quality. Substrates are thin wafers of semiconducting material needed for power devices. In its two-phase project, SixPoint Mate ...

ABSTRACT:In this project we seek to transition major recent developments in the mathematics of model reduction to industrial grade computing applications in liquid rocket combustion instability. From the mathematical side, we are interested in unsteady nonlinear dynamical systems which exhibit limit-cycle behavior and large oscillations and potentially discontinuous solutions. From the application ...

GaN-based devices are the basis of a variety of modern electronics applications, especially in optoelectronics and high-frequency / high-power electronics. These devices are based on epitaxial films grown on single-crystal wafers. The single-crystal wafer substrates are limiting because of their size, expense, mechanical properties and availability. If one could make GaN-based devices over large a ...

NanoSD, Inc. with its partners will develop a transparent, nanostructured thermally insulating film that can be applied to existing single-pane windows to reduce heat loss. To produce the nanostructured film, the team will create hollow ceramic or polymer nanobubbles and consolidate them into a dense lattice structure using heat and compression. Because it is mostly air, the resulting nanobubble s ...

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: 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: 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 ...
