New work is in progress on a CORBA interface standard for online interactive communication with DMIS-based Coordinate Measurement Machines (CMMs). This work is being pursued for submission to CAM-I via a recently organized object technology working committee of the North American DMIS Users Group. We will explore how to build upon this work for integration with existing manufacturing frameworks, e ...

MSI PROPOSES TO INCORPORATE BACKGROUND SUBSTITUTION OF "FAULTY MODELS" IN CAD DESIGN SIMULATION OF ELECTRONIC CIRCUITS TO PERFORM A "DESIGN OF EXPRIMENTS" DETERMINATION OF SENSITIVITY TO PARAMETRIC VARIATION IN COMPONENTS. THE INFORMATION LEARNED WILL BE USED TO SELECT COMPONENTS THAT WILL HAVE A LONGER LIFE, AND GREATER DURABILITY. THIS FORM OF ANALYSIS COMBINED WITH WORST CASE SENSITIVITY ANALYS ...

THE U.S. WEATHER SERVICE PRESENTLY USES A "TIPPING BUCKET" RAIN GAUGE FOR MEASURING RAIN ACCUMULATION. THIS DEVICE IS SENSITIVE TO WIND AND MOTION (AS ON BUOYS), CANNOT MEASURE RAIN RATE, AND REQUIRES FREQUENT MAINTENANCE, BECAUSE OF MOVING PARTS. AN ALTERNATIVE DEVICE IS BEING PROPOSED, WHICH INCORPORATES A RIGID, RESONANT TUBE, CLOSED AT THE TOP BY AN ELECTRO-ACOUSTIC TRANSDUCER, AND AT THE BOTT ...

The near-field scanning optical microscope can supply information on the shape and electrical properties of surfaces with nanometer resolution. The quantitative interpretation of images is difficult because of the difficulty of electromagnetic field solutions in the near-field limit. We propose to supply software to aid in this analysis. The finite-element programs generate two and three-dimension ...

The proposed research will develop the specifications and design of a ceilometer capable of scanning in three dimensions to detect clouds within a range of 75,000 feet (about 15 miles). The final design will be based upon the Vaisala CT-75k ceilometer which has a nominal range of 75,000 feet. As a proof-of- concept, the proposed research effort will use the Vaisala CT-25k (which has a nominal rang ...

Arca proposes research leading to development of a suite of methodology support products to help meet the need for innovative assurance techniques appropriate for emerging information technologies. The product will consist of a licensable methodology and supporting materials for specifying, building, and evaluating assurance arguments for products and systems based on the capability of security en ...

A growing number of fire fighters are suffering third degree burns; this has led to questions about the adequacy of thermal protective performance (TPP) measurements for protective clothing. A new heat flux sensor, whose response approximates that of skin, will be developed to provide better measurements of heat transfer in TPP tests. This sensor will be used with nonlinear parameter estimation an ...

We propose to characterize the early stage of consolidation of non-spherical powders to further the development of process models to enable simulation of powder metallurgy manufacturing for the consumer market, especially the automotive industry. Typically, spherical powders with a narrow size distribution are used for aerospace applications, while low-cost powders with irregular shapes and a wide ...

As fire protection engineering moves towards the implementation of performance- based fire codes, the use of validated fire models is becoming a necessity. Part of the validation process involves demonstrating model capabilities for predicting key fire environment parameters. One of the key parameters for estimating time to ignition and fire growth is the heat transfer rate to compartment surfaces ...
