Marcia Huber, Andrei Kazakov, Eric Lemmon
… the triple-point temperature to 525 K with pressures up to 30 MPa. It may be used to calculate all thermodynamic … for temperatures 270 K < T < 410 K and for pressures up to 30 MPa. For the vapor phase the estimated uncertainty in … for temperatures 230 K < T < 420 K and for pressures up to 30 MPa. The uncertainties are larger outside of these …

Effect of Flow-Pressure Phase on Performance of Regenerators in the Range of 4 K to 20 K

June 17, 2013
Author(s)
Michael A. Lewis, Ryan P. Taylor, Peter E. Bradley, Ray Radebaugh
… compressor, operating at the pulse tube warm end of about 30 K, as a controllable expander that can be used to vary the … EMF when the expander is operating at a temperature around 30 K. Our experimental results on the performance of a regenerator/pulse tube stage operating below 30 K show an optimum performance when the flow at the phase …

On the Collision Dynamics of a Water Droplet Containing an Additive on a Heated Solid Surface

August 1, 2002

Samuel L. Manzello, Jiann C. Yang
… upon a heated stainless steel surface. A solution of 30 % (mass fraction) sodium acetate trihydrate, CH 3 COONa 3 … of temperature to determine the Leidenfrost temperature of 30 % (mass fraction) sodium acetate trihydrate. Collision … varied from 20 C to above the Leidenfrost temperature of 30 % (mass fraction) sodium acetate trihydrate. The temporal …

Temperature Effects on Fatigue of Polymer Composites

July 1, 2000
Author(s)
Hai C. Tang, Tinh Nguyen, Tze J. Chuang, Joannie W. Chin, Hanchang F. Wu, J Lesko
… various environments: air, fresh water, and saltwater at 30 C. This study continues to investigate the effects on … aqueous environments at 65 oC is about the same as that at 30 oC, but the fatigue life at 4 oC is significantly longer than that at 30 oC.Based on these experimental data, the material …

Measurement of the Optical Extinction Coefficients of Post-Flame Soot in the Infrared

July 1, 2003
Author(s)
J F. Widmann, Jiann C. Yang, Samuel L. Manzello, George W. Mulholland
The optical extinction coefficients of post-flame soot have been measured in the wavelength range 2.8 micrometers to 4.1 micrometers. A laminar diffusion burner was combined with an infrared spectrograph and gravimetric measurements to determine the mass

Toxic Potency Values for Smoke from Products and Materials

Pseudo-exhaustive Verification of Rule Based Systems

July 1, 2018
Author(s)
David R. Kuhn, Dylan J. Yaga, Raghu N. Kacker, Yu Lei, Chung Tong Hu
Rule-based systems are important in application domains such as artificial intelligence and business rule engines, as well as formal methods for software design. When translated into an implementation, simple expressions in rules may map to thousands of
