Aspects of a Product Model Supporting Apparel Virtual Enterprises

October 1, 1996
Author(s)
Peter O. Denno
Emerging computer technology, including an infrastructure for virtual enterprises and more capable apparel product development software, is providing an opportunity to reinvent how apparel is produced. The development of an information-rich and unambiguous

Fast, Three-Dimensional, Collision-Free Motion Planning

April 10, 1986
Author(s)
Martin Herman
Issues dealing with fast, 3-D, collision-free motion planning are discussed, and a fast path planning system under development at NBS is described. The components of a general motion planner are outlined, and some of their computational aspects are

Chlorination in Combustion Systems

December 1, 2000
Author(s)
Wing Tsang, Valeri I. Babushok
This paper is concerned with the formation of polychorinated organics in the gas phase in combustion systems. The results are derived from simulation studies with inputs from the fundamental kinetics of single step thermal gas phase reactions. Attention is

A History of Fire Testing: Past, Present, and Future.

March 30, 2009
Author(s)
James R. Lawson
… century with the development of digital data logging, computing, data analysis, and scientifically based predictive models. Digital computing has opened the theoretical world that provides …

Controlling solute trapping and solute drag in a phase-field model

March 16, 2023
Author(s)
Arnab Mukherjee, James A. Warren
The finite solid-liquid interface width in phase-field models results in non-equilibrium effects, including solute trapping. Prior phase field modeling has shown that this extra degree of freedom, when compared to sharp-interface models, results in solute

Determination of Individual Building Performance Targets to Achieve Community-Level Social and Economic Resilience Metrics

May 2, 2022
Author(s)
Wanting (Lisa) Wang, John W. van de Lindt, Brad Hartman, Harvey Cutler, Jamie Kruse, Therese P. McAllister, Sara Hamideh
The retrofit of wood-frame residential buildings is a relatively effective strategy to mitigate damage caused by windstorms. However, little is known about the effect of modifying building performance for intense events such as a tornado and the subsequent

Large Change of Interlayer Vibrational Coupling with Stacking in Mo 1-x W x Te 2

January 7, 2022
Author(s)
John A. Schneeloch, Yu Tao, Jaime Fernandez-Baca, Guangyong Xu, Despina Louca
Stacking variations in quasi-two-dimensional materials can have an important influence on material properties, such as changing the topology of the band structure. Unfortunately, the weakness of van der Waals interactions makes it difficult to compute the

AMB2018-03: Benchmark Physical Property Measurements for Material Extrusion Additive Manufacturing of Polycarbonate

October 29, 2020
Author(s)
Daniel P. Cole, Frank Gardea, Todd C. Henry, Jonathan Seppala, Edward Garboczi, Kalman D. Migler, Christopher M. Shumeyko, Jeffery R. Westrich, Sara Orski, Jeffery L. Gair
Material extrusion (MatEx) is finding increasing applications in additive manufacturing of thermoplastics due to the ease of use and the ability to process disparate polymers. Since part strength is anisotropic and frequently deviates negatively with

Superionic UO2: A Model Anharmonic Crystalline Material

May 7, 2019
Author(s)
Jack F. Douglas, Hao Zhang, Xinyi Wang, Alexandros Chremos
Crystalline materials at elevated temperatures and pressures can exhibit properties more reminiscent of simple liquids than ideal crystalline materials, an attribute making these materials useful in diverse applications. Superionic crystalline materials

Cements in the 21st Century: Challenges, Perspectives, and Opportunities

April 21, 2017
Author(s)
Joseph J. Biernacki, Jeffrey W. Bullard, Gaurav Sant, Nemkumar Banthia, Frederik P. Glasser, Scott Jones, Tyler Ley, Richard A Livingston, Luc Nicoleau, Jan Olek, Florence Sanchez, Rouzbeh Shahsavari, Paul E. Stutzman, Sobolev Konstantin, Tracie Prater
In a book published in 1906, Richard Meade outlined the history of portland cement up to that point1. Since then there has been great progress in portland cement-based construction materials technologies brought about by advances in the materials science
