Real-Time Measurements of Condensed-Phase Spectra in Burning Polymers

January 1, 1999
Author(s)
Marc R. Nyden
A major goal of the Building and Fire Research Laboratory is to provide the polymer industry with the technical understanding and measurement tools that are needed to develop a new generation of fire resistant materials. In the pursuit of this goal, we

Real-time Single-workstation Obstacle Avoidance Using Only Wide-field Flow Divergence

January 1, 1999
Author(s)
Theodore(Ted) Camus, David Coombs, Martin Herman, Tsai Hong Hong
This paper describes a real-time robot vision system which uses only the divergence of the optical flow field for both steering control and collision detection. The robot has wandered about the lab at 20 cm/s for as long as 26 minutes without collision

Review of Primary Methods Applicable to Key Comparisons in Acoustics

January 1, 1999
Author(s)
Victor Nedzelnitsky
Historically, various techniques have been used in acoustics to attempt to establish and to measure sound pressures in the pressure field (spatially uniform amplitude of sound pressure, as in a suitable coupling cavity that is small compared to a
