While much of the data involved in product and order definition has been captured in standard electronic structures such as IGES and EDI, material and process specifications are still handled as amorphous, paper-based documents. The use of manual, text-based specifications is an extremely labor-intensive and time-consuming process. Specifications are an integral part of the product and order defin ...

Precision underwater mapping is an important requirement of projects ranging from wreck surveys and environmental impact studies to mine clearing operations and marine science projects. Small Autonomous Underwater Vehicles (AUV) are capable platforms for mapping operations as they are easily deployed and can operate in hazardous environments. We propose the development of an Automated Imaging and ...

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 ...

The technique of screen printing has been demonstrated to be of practical benefit in numerous engineering applications. Over the past two decades, these benefits have been widely recognized by the electronics industry, as evidenced by the flourishing fields of screen-printed thick-film electronics. Multilayer circuits are now manufactured by the sequential deposition of conductive and resistive pa ...

The objective is to develop a horizontal ADCP (HADCP) for mapping horizontal flow structure in channels, harbors, and ports. This would be useful in areas where currents pose a threat to safe boat navigation. The Challenge for such a system is to measure flow even though bottom and surface returns could contaminate the profiles. Phase 2 will develop a long range HADCP using a frequency of approxim ...
