Introduction to the Special Issue on Biothermodynamics

May 14, 2012
Author(s)
Robert N. Goldberg
In its broadest sense, biothermodynamics encompasses all thermochemical and thermophysical property measurements and calculations on biochemical and biological systems. This makes for an extremely broad field given the large number of properties and the

Universal Relationships in Sooting Methane-Air Diffusion Flames

January 1, 1998
Author(s)
C. R. Kaplan, G P. Patnaik, K. Kailasanath
The laminar flamelet concept is based on the premise that scalar properties in laminar diffusion flames are nearly universal functions of mixture fraction. It has been well-tested and proven for temperature and the major species, however, few studies have

Timing Studies of Real-Time Linux for Control

April 1, 2002
Author(s)
Frederick M. Proctor, William P. Shackleford
Linux is being used increasingly for real-time control of industrial equipment. Versions of Linux adapted to support deterministic task execution are freely available. The resolution of task timing is much higher than for typical user-level processes, on

7. THERMODYNAMIC PROPERTIES OF MIXTURES

February 7, 2023
Author(s)
Rich Elliott, Vladimir Diky
… mass, or volume fractions. Formulas are also presented for computing the fugacity coefficients of several commonly used …

Pair Correlation Functions in Mixtures of Lennard-Jones Particles

June 3, 2008
Author(s)
Raymond D. Mountain, Yedhud A. Ben-Naim
The pair correlation functions for a mixture of two Lennard-Jones (LJ) particles were computed by both the Percus-Yevick equations and by molecular dynamics. The changes in the pair correlation function resulting from changes in the composition of the

Thermodynamics of Enzyme-Catalyzed Reactions

March 1, 2003
Author(s)
Robert N. Goldberg, Yadu D. Tewari
This review, which has been prepared for the McGraw-Hill 2003 Yearbook of Science and Technology, gives an overview of the thermodynamics of enzyme-catalyzed reactions. Topics include the thermodynamic formalism(s) used in this field, computational methods

SQUIDs Past, Present, and Future: A Sympsium in Honor of Jim Zimmerman

October 1, 2000
Author(s)
Richard L. Kautz
… became coinventor of the radio-frequency Superconducting Quantum Interference Device and coined the name SQUID. A … magnetic fields, the SQUID is limited only by fundamental quantum uncertainties, and its potential was immediately …

Near-Field, Spherical-Scanning Antenna Measurements With Nonideal Probe Locations

October 12, 2021
Author(s)
Ronald C. Wittmann, Bradley Alpert, Michael H. Francis
We introduce a near-field, spherical-scanning algorithm for antenna measurements that relaxes the usual condition requiring data points to be on a regular spherical grid. Computational complexity is of the same order as for the standard (ideal-positioning)

Fire Dynamics Simulator (Version 4) - Technical Reference Guide

March 1, 2006
Author(s)
Kevin B. McGrattan
Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software described in this document solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow with an

Fire Dynamics Simulator (Version 4) - User's Guide

We introduce a near-field spherical scanning algorithm that relaxes the usual condition requiring data points to be on a regular spherical grid. Computational complexity is of the same order as for the standard (ideal-positioning) spherical-scanning

A Representation of Acoustic Waves in Unbounded Domains

October 1, 2002
Author(s)
Bradley K. Alpert, Yu-Hsuan Chen
Compact, time-harmonic, acoustic sources produce waves that decay too slowly to be square-integrable on a line away from the sources. We introduce an inner product, arising directly from Green's second theorem, to form a Hilbert space of these waves, and

Measuring Performance and Intelligence of Intelligent Sytems White Paper 2001

August 4, 2001
Author(s)
Elena R. Messina, Alex Meystel, Larry H. Reeker
Is the measurement of performance for intelligent systems different than that of non-intelligent systems? In this white paper, we explore the various dimensions of evaluation of intelligence and performance. The main areas we tackle are the testing of

Report of Scoping the Apparel Manufacturing Enterprise

May 1, 1993
Author(s)
Howard T. Moncarz, Yung-Tsun Lee
This paper identifies a set of manufacturing data interfaces that could be standardized for the effective computer integration of the information required to operate an apparel manufacturing enterprise. The interfaces are called Application Protocols. A

Predicting Lattice Parameters from Atomic-Scale Images of Two Dimensional Materials Using Deep Learning

December 15, 2025
Author(s)
Sayak Chakrabarty, Kamal Choudhary, Youjia Li, Daniel Wines, Vishu Gupta, Muhammed Nur Talha Kilic, Alok Choudhary, Ankit Agrawal
Determining lattice parameters in two-dimensional (2D) materials is essential for materials characterization and discovery. In this work, we propose a deep-learning-driven pipeline that addresses the regression task of estimating the lattice constants (a)
