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.

Automatic speech recognition (ASR) technology is in wide use today and has been successfully integrated into a number of applications. Although there are also many potential applications for automatic speaker identification (SID), SID accuracy rates are generally not sufficient for widespread use in practical applications. For high accuracy ASR and SID, the microphone must be located near the talk ...

Toyon Research Corp. and the Penn State Univ. propose research and development of innovative algorithms for classifying objects and activities observed in high-dimensional data extracted from multi-sensor motion imagery. The proposed algorithms include novel feature clustering techniques to enable effective characterization of intra-class and inter-class appearance variations in datasets containin ...

A key objective of our project is to develop advanced algorithms and software to track people and vehicles in an urban environment using video imagery from multiple unmanned aerial vehicles (UAVs). Track continuity of targets of interest (TOI) is an essential requirement. Collaborative UAV trajectory planning and camera pointing to collect continuous observations on one or more TOI by a team of UA ...

Superconductor Technologies Inc. (STI) is the worldwide leader in the manufacture of high-temperature superconductor (HTS) receive filter systems for commercial and military applications. STI has deployed nearly 6,000 such filter systems having a cumulative run time of over 165 million hours and an MTBF of over 500,000 hours. STI¡¦s highly selective and sensitive RF filters are fabricated from H ...

It is desirable to make a new generation of electromagnetic wave (EM) detectors that are (a) capable of providing true multispectral imaging & (b) wavelength agile over the visible through sub-mm wave (THz) region. In Phase I, the Tanner/Stanford team demonstrated that plasmon lensing can be used to provide multispectral imaging. Prototypes of such detectors were fabricated in the visible region ...

In this program, HyPerComp and University of Michigan have teamedtogether to develop a high-order grid generator for Euler and viscousmeshes. The grid generator is based on HyPerComps successful generalpurpose CAD2Mesh software and is being integrated with HyPerCompsHDphysics and U. Michigans XFlow DG high-order solvers. High-order gridgeneration methods are being implemented to accurately capture ...

This work will focus on the development of monolithic SWIR focal plane array technologies using CMOS or CMOS compatible fabrication technology. This will be realized on a Silicon substrate and incorporate APD+TIA arrays and be scalable to Megapixel arrays and coherent receiver operation for capture of the full optical wavefront vector information.

Unmanned aircraft systems (UAS) are increasingly seen as a cornerstone in developing the future Defense infrastructure and it is critical that they collaborate efficiently and execute complex missions in denied environments. Although great progress has been made in GPS-denied navigation, the target handoff problem in GPS-denied environments has not been extensively studied. In this problem, a trac ...

Coating materials and coating methods used to protect U.S. military aircraft and weapon systems from corrosion and wear are in need of environmentally benign alternatives in order to keep up with dynamic regulations associated with environment, safety, and occupational health. Thus, the Air Force is supporting research to develop alternatives to the dangerous materials identified on the OSD Emergi ...
