Computerizing Concrete Technology Knowledge

December 1, 1999
Author(s)
G J. Frohnsdorff, L J. Kaetzel
The ability to organize, store, process, and exchange knowledge of concrete using computers is growing rapidly. Without fully knowing what will be possible in the future, it is apparent that computers will bring great changes to the way knowledge of

Quantifying Fire Model Evaluation Using Functional Analysis

January 1, 1999
Author(s)
Richard D. Peacock, Paul A. Reneke, William D. Davis, Walter W. Jones
Comparisons of predictive fire models with each other or with experimental data have been largely qualitative. By treating these time series curves as infinite-dimensional vectors, a branch of mathematics called functional analysis defines geometrically

A New Experiment for Determining Evaporation and Condensation Coefficients of Cryogenic Propellants

March 1, 2016
Author(s)
Kishan Bellur, E F. Medici, M Kulshreshtha, V Konduru, D Tyrewala, A Tamilarasan, J McQuillen, Juscelino Leao, Daniel S. Hussey, David L. Jacobson, Julia Scherschligt, J Hermanson, C Choi, J Allen
Passive and active technologies have been used to control propellant boil-o , but the current state of understanding of cryogenic evaporation and condensation in microgravity is insucient for designing large cryogenic depots critical to the long-term

Images of Strips On and Trenches In Substrates

January 1, 2007
Author(s)
Egon Marx
The computation of images of lines or strips on a substrate and trenches in a substrate or a layer above a substrate, all made of dielectric or absorbing materials, using integral equations equivalent to Maxwell's equations and using Fourier optics are

Analysis of Robotic Vehicle Steering and Controller Delay

August 17, 1994
Author(s)
Karl Murphy
Robotic vehicles are driving at highway speeds using computer vision and other methods to detect the vehicle¿s position on the roadway. Several factors affect system performance and stability. In this paper a simple vehicle and path following model is
