A combustion environment can be described by a characteristic fuel-to-air ratio normalized by the stoichiometric fuel-to-air ratio, otherwise defined as an equivalence ratio, _. The equivalence ratio is used extensively in a wide range of combustion fields from fundamental flame studies, to full-scale fire testing, to power plant operations. There have been basically two methods for calculating ...

We propose a 6 month program during which we will develop and demonstrate an approach for generating well-characterized atomic and molecular beams of metastable species. Such beam sources are necessary for the microelectronics and plasma processing industries because they would provide a valuable tool required to establish a solid database of plasma-related collision processes. This improved and e ...

IGES Data Analysis, Inc. (IDA) (formerly IGES Data Analysis) proposes to develop a specification and implementation for the viewing of IGES files on the Internet's World Wide Web (Web). This project will evaluate the different uses of IGES and attempt to determine a base graphic subset that will provide the most benefit to users of the Web. IDA will use the currently posted IGES Figure Viewer Spec ...

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 ...

The coming information superhighway sets the stage for how we will work and play in the next millennium; building upon the Internet along with powerful new Internet tools such as the World Wide Web. By every measure, the Internet and the Web are experiencing exponential growth. The amount and variety of data on the Net makes it increasingly difficult to find specific information of interest - fo ...

This proposal will emphasize outfitting a virtual classroom and creating a skills (CNC) oriented training program. The virtual classroom will involve contextual learning using a realistic simulation of the manufacturing environment. The simulation will have all of the characteristics of a machine shop, but will allow the learner to explore and experiment ("discover") in ways that would not be pr ...

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 ...

Fire fighter burn injuries continue to be a frequent problem despite significant advances in protective clothing. A reason for this is the buildup of moisture in fire fighting garments as a result of sweating or fire fighting activities. This buildup of moisture increases the heat transfer through the garment and can result in scald burn injuries as the water is quickly heated. Currently, there is ...
