Gas Metal Arc Welding (GMAW) accounts for a significant proportion of all welding performed. Due to its relatively high speeds and metal deposition rates as well as relatively low equipment and maintenance costs, it is also the most popular process for automated, and especially robotic, welding. There are, however, problems that significantly restrict its manufacturing applications. The efforts at ...

Algal toxins can cause mass mortality of wild and farmed fish, contaminate shellfish beds and cause human illnesses from consumption of these products. Dinoflagellates are widely recognized to be the primary algae associated with toxic red tide blooms. Once established, harmful algal blooms typically are mono-specific. The bio-optical "fingerprint" of the bloom, related to the specific pigment com ...

A Shortfall in marine fisheries production is driving the development of aquaculture technologies on many fronts. Recirculating systems are regarded as critical components of many development schemes. However, interest and use of recirculating systems for production of marine organisms have lagged behind freshwater applications. A floating bead filter which is corrosion resistant (no metal parts), ...

Although many tools have been developed to aid the conversion of pre-existing documents from proprietary work processor formats to HTML for access via the World Wide Web and related Intranet documentation access systems, such as the Intelligence Community's Intelink system, few tools exist to aid the automatic discovery and implementation of hypertext links between related documents. This proposal ...

There is a need for accurate and cost effective airborne techniques to estimate fish biomass in the open ocean. Arete proposes to develop in Phase I optimal detection algorithms using existing imaging LIDAR data collected with the Fisheye(R) sensor. These algorithms will be developed to allow real-time detection of fish and fish schools, discrimination between fish and ambient clutter, and discr ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

PROGRESSION OF MOLTEN POOL, FORMED IN SEVERE ACCIDENT SCENARIOS, IS STRONGLY DEPENDENT ON ITS HEAT TRANSFER CHARACTERISTICS. THE PURPOSE OF THE PROPOSED RESEARCH IS TO PERFORM A COMPUTATIONAL ANALYSIS OF THE TURBULENT NATURAL CONVECTION IN INTERNALLY HEATED POOLS. TWO VERSIONS OF THE LOW-REYNOLDS-NUMBER MODELS WILL BE FIRST VALIDATED FOR THE PREDICTION OF TURBULENT NATURAL CONVECTION FLOWS OF INTE ...

The Small Business Innovation Research Phase 1 project will improve the practical utility of a new approach for detecting and sizing sub-0.1 m particles in vacuum processes used in semiconductor manufacturing. Particle contamination during the processing of silicon wafers is a major source of yield loss in semiconductor manufacturing. Current generation laser scattering monitors are not sensitive ...

A SMALL SCALE WASTE COLLECTION SYSTEM WILL BE DESIGNED AND EVALUATED TO DETERMINE POTENTIAL EFFECTIVENESS OF FOUR DIFFERENT DEGREES OF CONTAINMENT OF NET PANS; 5, 50, 60, AND100 PERCENTS. EFFECTIVENESS OF THE COLLECTION UNIT WILL BE EVALUATED BY MONITORING EFFICIENCY OF PHOSPHOROUS, SUSPENDED SOLIDS AND DOB LOAD REMOVAL AT EACH OF THE FOUR CONFIGURATIONS. OTHER OPERATIONAL AND ENVIRONMENTAL PROBLE ...
