The Sandia APAR-3G system: Automatic Programming, Recording, and Control for Development and Production Testing

Description: Abstract: The APAR-3G system is an automatic programming, controlling and recording machine which is readily adaptable to a wide variety of automated data acquisition and constrol system applications. It is physically and logically modular to permit the assemby of minimum or maximum capability machines. This system can perform the necessary acquisition and control in a typical factory environment and can generate an output (for data reduction) which is compatible with available computer system… more

Irreducible Representations of Line Groups: the Dynamics of Polymer Chains

Description: Abstract: "The symmetries of infinite polymer chain molecules are discussed using the concept of line groups. Explicit directions are given for obtaining the irreducible representations of line groups employing the formalism developed for three-dimensional space groups. Line groups containing primitive and nonprimitive operations are discussed. Detailed considerations of the line group Vh are given with specific applications to the polyethylene molecule. Directions for generating symmetry-adapt… more
