Modeling and Analysis of Single-Plate Shear Connections Under Column Loss

May 8, 2013
Author(s)
Joseph A. Main, Fahim Sadek
This paper presents a computational assessment of the behavior of single-plate shear (“shear tab”) connections in gravity frames under column loss scenarios. Two-span beam assemblies are considered under pushdown loading of the unsupported center column

The New Golden Age of Algorithms and Data Structures

October 29, 2012
Author(s)
Paul E. Black
… been invented? We don't think so. With isochronous computing, heterogeneous multiprocessors, energy aware computing, wear-leveling (flash), cache and other anisotropic memory, distributed computing, streaming environments, functional languages, etc. …

Finite-Element Analysis of Flexible Fixturing System

May 29, 1987
Author(s)
Jonathan W. Lee, L Haynes
A computer software has been developed for the analysis and design of fixtures. This software can lead the designer to the optimal design of the fixturing system which minimizes the total work done on the workpiece, the fixturing force, the deformation

Object Measurements from 2D Microscopy Images

December 11, 2020
Author(s)
Peter Bajcsy, Joe Chalfoun, Mylene Simon, Mary C. Brady, Marcin Kociolek
This chapter addresses object measurements from 2D microscopy images. Object measurements (called image features) vary in terms of theoretical formulas for the same image feature, the physical units used to represent pixel-based measurements, the

Thermodynamic assessment of the Co-Ta system

December 20, 2018
Author(s)
Peisheng Wang, J?rg Ko?mann, Ursula R. Kattner, Mauro Palumbo, Thomas Hammerschmidt, Gregory B. Olson
The Co-Ta system has been reviewed and the thermodynamic description was re-assessed in the present work. DFT (density functional theory) calculations considering spin polarization were performed to obtain the energies for all end-member configurations of

Thermodynamic re-assessment of the Co-Al-W system

October 2, 2017
Author(s)
Peisheng Wang, Wei Xiong, Ursula R. Kattner, Carelyn E. Campbell, Eric Lass, Oleg Y. Kontsevoi, Gregory B. Olson
The Co-Al-W system and its binary sub-systems Al-Co, Al-W and Co-W were critically reviewed. The thermodynamic description of the Co-Al-W system including all three binaries was developed considering thermodynamic and constitutional data of the systems

Data Resources for Thermophysical Properties of Metals and Alloys, Part 1: Structured Data Capture from the Archival Literature

January 7, 2017
Author(s)
Boris Wilthan, Erik A. Pfeif, Vladimir Diky, Robert D. Chirico, Ursula R. Kattner, Kenneth G. Kroenlein
In support of the continuous scientific and industrial need for accessible and high-quality thermophysical property data for metals and alloy systems, NIST/TRC is expanding its data archiving and critical evaluation activities to include this area. As part
