A defect-driven diagnostic method for machine tool spindles

December 31, 2015
Author(s)
Gregory W. Vogl, M A. Donmez
Simple vibration-based metrics are, in many cases, insufficient to diagnose machine tool spindle condition. These metrics couple defect-based motion with spindle dynamics; diagnostics should be defect-driven. A new method and spindle condition estimation

Design of a 1 DOF MEMS motion stage for a parallel plane geometry rheometer

December 31, 2015
Author(s)
Yong Sik Kim, Nicholas Dagalakis, Chiara C. Ferraris, Svetlana Avramov-Zamurovic1
Rotational rheometers are used to measure paste properties, but the test would take too long to be useful for a quality control (QC) on the job site. In this paper, a new type of rheometer is proposed based on a one degree of freedom (DOF) micro-electro

Effect of Common Faults on the Performance of Different Vapor Compression Systems

December 31, 2015
Author(s)
Zhimin Du, Piotr A. Domanski, William V. Payne
The effect of faults on cooling capacity, COP, sensible heat ratio, and superheat/subcooling temperatures in five split and rooftop systems, which use different types of expansion devices, compressors and refrigerants, are separately compared and analyzed

ThermoData Engine (TDE) Version 10 (Pure Compounds, Binary Mixtures, Ternary Mixtures, and Chemical Reactions): NIST Standard Reference Database 103b

December 31, 2015
Author(s)
Vladimir Diky, Chris Muzny, Alexander Smolyanitsky, Ala Bazyleva, Robert D. Chirico, Joe W. Magee, Eugene Paulechka, Andrei F. Kazakov, Scott Townsend, Eric Lemmon, Michael D. Frenkel, Kenneth Kroenlein
The ThermoData Engine is a software expert system implementing the concept of dynamic data evaluation for thermophysical and thermochemical properties of, primarily, organic compounds. This new release provides a substantially expanded database of
