Error Prevention and Detection in Data Preparation for a Numerically Controlled Milling Machine

January 1, 1987

Author(s)

Thomas Kramer, W Strayer

In the Vertical Workstation (VWS) of the NBS Automated Manufacturing Research Facility, metal parts are machined automatically from a feature-based design. A simple two-and-a- half dimensional part may be designed and machined within an hour, allowing half

Evidence for Free Electron-Like Stoner Excitation in Fe

January 1, 1987

Author(s)

David R. Penn

An analysis of spin-polarized electron-energy-loss experiments in Fe is described which suggests that (1) free-electron-like Stoner excitations are far more probable than the usual type and (2) exchange events involving relatively large energy losses are

Exergy Analysis of Heat Pumps

January 1, 1987

Author(s)

T. L. Tsaros, R. A. Gaggioli, Piotr A. Domanski

The HPSIM computer program for modeling heat pumps (Domanski and Didion 1983) has been augmented to include exergy analysis. Exergy transports between the components, to the loads, and to the environment are evaluated. The exergy consumptions in each

Experimental Measurements of Condensation on Vertical Plates With Enhanced Fins

January 1, 1987

Author(s)

Mark A. Kedzierski

Fins were accurately machine on vertical plates with the electric discharge (EDM) process. Condensation heat transfer data for various fin shapes were used to experimentally demonstrate the importance of large curvature and curvature gradients for surface

Experimental Studies of Surface Magnetism with Polarized Electrons

January 1, 1987

Author(s)

Daniel T. Pierce

The same electron spectroscopies that are so powerful for studying surfaces generally, can be made sensitive to magnetic properties when electron spin polarization is included as a parameter, for example by probing with a spin polarized electron beam or
