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 ...

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 ...

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 ...

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 feasiblity of developing a PC based, pulsed ultrasonic test system for the economical and reliable testing of aluminum cylinders for sustained load cracking is addressed. A system consisting of a host PC, ultrasonic pulser/receiver and data acquisition hardware, control and analysis software, and transducer fixture for accurate positioning is proposed. In addition to the system development, ...

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 ...

Soaking and co-crystallization experiments for studying the binding of potential drugs with proteins of known structure are a significant research function of crystallographic labs in pharmaceutical companies. Such experiments have two overriding characteristics: (a) the experiments are repetitive, and therefore become routine, and (b) numerous experiments are performed to acquire the desired in ...

Recent catastrophic failures of Self Contained Underwater Breathing Apparatus (SCUBA) aluminum gas cylinders and similar air tanks have generated the need for a highly reliable, low cost inspection method to insure the integrity of these tanks. The failures of these tanks have been the result of crack formation in the neck and shoulder area. The cracks originate from the interior wall and can re ...

The storage photostimulable phosphor (SPP) technique has been demonstrated to be sensitive to ionization radiation. It is especially suited for detecting alpha particles since the efficiency is practically 100%. In addition to being able to quantify total ionization deposited in a SPP sensor, it also captures the radiation source distribution information in a digital image which can be readily ana ...

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 ...
