The placement of hyperspectral sensors on future Unmanned Air Vehicles is constrained by a data bottleneck caused by the limited downlink bandwidth. This proposal addresses this problem by developing a lossless compression algorithm that is optimized for hyperspectral imagery. Hyperspectral imagers generate 3-D data whose two axes correspond to spatial directions and the third to spectral respon ...

Critical issues associated with the design of a rugged, compact "real time" sampling system using photoconductive switches as the signal generator and sample will be investigated. The design concept is based upon an optoelectronic equivalent time sampling principle developed by the Principal Investigator. It involves first the phase locking of the temporal waveform to be measured to the optical pu ...

The research proposed herein in intended to solve two problems, namely (1) to define a specification framework for access control policies that enables policy composition for both centralized and distributed systems in a precise and systematic manner, and (2) to explore the impact of different security architectures on policy composition. Although most commercial systems support applications that ...

Bacterial pathogens in salmonids, such as Renibacterium salmoninarum and Aeromonas salmonicida, are difficult to identify by conventional diagnosis due to their extremely slow growth and the absence of an efficient selective medium. Diseases caused by these pathogens represent a serious problem both in the fishing industry and for conservation efforts. While several PCR-based assays appear to be u ...

A novel beamforming network is proposed to electronically scan two independent beams in a conformal phase array. The beamformer utilizes ferroelectric materials in the RF distribution network to control the amplitudes and phases of the array element excitations. One beamformer board is required for each beam and four low power DC voltages per beamformer are needed to achieve total hemispherical ...

Big Light Technology, Inc. proposes to develop a light weight, comfortable, flexible, form fitting instrumented garment. The instrumented garment will be capable of monitoring the skin temperature at multiple localized torso locations using fiber-optic sensors incorporated on a single optical fiber. The sensors are passive and will therefore require no external power. The method for monitoring ...

Production Products will develop a lightweight, modular, easily deployable barrier system that will be based on out proven polyurethane composite technology that has demonstrated the ability to absorb very high levels of elongation and energy without failure. This material can be elongated 500% repeatedly and still returns to it's original shape. We will design a barrier system around this struc ...
