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 ...

Commercial aviation offers a low cost platform from which to make extensive humidity measurements, provided the instrumentation can run autonomously and endure the rigorous flight schedules. Advances in state of the art diode laser gas sensing technology make possible compact, fully automated, self-calibrating instrumentation with the sensitivity needed to measure humidity levels throughout the tr ...

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 ...

The identification of a requirement for an advanced, user friendly high speed, short exposure (50-100nsec) electronic CCD Camera system to improve and further the investigation of thermal spray methods through detailed and accurate analysis encourages and accelerates the opportunity to develop a state of the art multiple exposure high speed video camera. This proposal is intended to enable the res ...

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 ...

HYPRES proposes the development of Digital-to-Analog Converter (DAC) with extremely high accuracy and linearity. The DAC is based on the processing of magnetic flux quanta in an integrated superconductive circuit. The device uses a stable reference ac signal at relatively low frequency (below 100 MHz). This frequency is multiplied on chip up to 48 GHz. The operation of the device is based on the d ...

Recent years have seen a great increase in the use of a variety of computer applications for modeling enterprise processes, notably, in the areas of simulations, planning, scheduling, and workflow. Currently, however, there are no robust mechanisms to support the exchange of the information in those models. Lately this problem has been addressed by a number of research efforts. The focus of these ...

A diode laser method for the real-time measurement of absolute flux concentrations and spatial profiles of atomic beams used in MBE will be tested. The proposed method uses the doubled output of a near-infrared diode laser to access atomic absorption lines of species such as Ga, Al and In. The detection method will combine high frequency wavelength modulation and noise canceler approaches in order ...
