A Talk on NMR Applied to Polymer Research Given at the Eastern Analytical Symposium - November 14, 1962

Description: The nature and types of internal molecular and thermal motions that polymer chains and polymer segments undergo have a great bearing on the physical behavior of polymeric solids. A relatively new tool is now available that permits us to observe and study internal thermally-induced motions directly at the atomic or molecular level rather than from macroscopic observations. this tool is nuclear magnetic resonance spectroscopy. This talk discusses (1) the nature of nuclear magnetic resonance, (… more

Test Program for 30 Megawatt Prototype Sodium Intermediate Heat Exchanger and Steam Generator

Description: The designer's concept of a test program for the 30-Mw prototype intermediate heat exchanger and steam generator designed and fabricated as part of the Sodium Components Development Program is presented. The performance data will serve to verify the thermal design, or allow application of improved techniques to future designs, give an improved basis for stress analysis in design of future units, and demonstrate the capability and limitations of the units in relation to the performance specifica… more

On the Generalized Overrelaxation Method for Operator Equations

Description: "In Householder, using Weissinger's identity , obtained the necessary and sufficient conditions for the c onvergence of the Seidel method for the solution of finite matrix equations of the form (D-S-S*-F)u = f. The same coniditions were also obtained by Krein and Prozorovakaya for an analog of the Seidel method for the operator equations of the form (D+S+S*)u = f in a Hilbert space. The purpose of this article is to extend the result of the above authors to the generalized overrelaxation iter… more
