Demonstration of Real-Time Tactical Decision Aid Displays

August 1, 2007
Author(s)
William D. Davis, David G. Holmberg, Paul A. Reneke, L D. Brassell, R Vettori
On September 22, 2005 the National Institute of Standards and Technology (NIST) conducted a demonstration of two prototype tactical decision aid computer interfaces in the city of Wilson, North Carolina. Members of the City of Wilson Fire Department

Chaotic Scattering and Escape Times of Marginally Trapped Ultracold Neutrons

April 1, 2004
Author(s)
Kevin Coakley, J M. Doyle, S N. Dzhosyuk, L Yang, Paul R. Huffman
We compute classical trajectories of Ultracold neutrons (UCNs) in a superconducting Ioffe-type magnetic trap using a symplectic integration method. We find that the computed escape time for a particular set of initial conditions (momentum and position)
