Fast Path Planning in Unstructured, Dynamic, 3-D Worlds

April 21, 1986
Author(s)
Martin Herman
Issues dealing with fast motion planning in unstructured, dynamic 3-D worlds are discussed, and a fast path planning system under the development at NBS is described. It is agued that an octree representation of the obstacles in the world leads to fast

Fast, Three-Dimensional, Collision-Free Motion Planning

April 10, 1986
Author(s)
Martin Herman
Issues dealing with fast, 3-D, collision-free motion planning are discussed, and a fast path planning system under development at NBS is described. The components of a general motion planner are outlined, and some of their computational aspects are

Mass spectrometric study of 1,2,4- and 1,3,4-oxadiazoles containing indole substituents.

April 1, 1986
Author(s)
Anzor Mikaia, Rosa Ushakova, Vladimir G. Zaikin, VI Kelarev, GA Shveikhgeimer
Under electron ionization major fragmentation pathways for indolyloxadiazoles proceed via cleavage of C-O, C-N and N-O bonds in the oxadiazole ring. Skeletal rearrangements due to a migration of aryl groups are detected for diaryl1,3,4-oxadiazoles.

The Vertical Machining Workstation of the AMRF: Software Integration

April 1, 1986
Author(s)
Charles R. McLean
The software architecture of the Vertical Machining Workstation (VWS) in the Automated Manufacturing Research Facility (AMRF) at the National Bureau of Standards is presented. The prototype system demonstrates flexible computer-integrated manufacturing for

Spin Dependent Superelastic Scattering from Pure Angular Momentum States of Na(3P)

March 31, 1986
Author(s)
Jabez McClelland, Michael H. Kelley, Robert Celotta
Spin asymmetries are presented for superelastic scattering of spin-polarized electrons from spin-polarized M L=+1 and M L=-1 states of the Na 3P 3/2 atom. The incident-energy dependence at a scattering angle of 30° is shown for energies of 1.26 to 11.76 eV
