Investigating predictive metamodeling for additive manufacturing

August 21, 2016
Author(s)
Zhuo Yang, Douglas Eddy, Sundar Krishnamurty, Ian Grosse, Peter O. Denno, Felipe F. Lopez
Additive manufacturing processes offer significant commercial advantages due to unique and advanced process capabilities. Production of metal parts can involve trial and error. This is often due to limited understanding of variability in properties and the

Computer-Aided Molecular Design and Selection of CO2 Capture Solvents Based on Thermodynamics, Reactivity and Sustainability

Alexandros Chremos, Athanasios Papadopoulos, Sara Badr, Esther Forte, Theodoros Zarogiannis, Panos Seferlis, Stavros Papadokonstantakis, Amparo Galindo, George Jackson, Claire Adjiman
The identification of improved carbon dioxide (CO2) capture solvents remains a challenge due to the vast number of potentially-suitable molecules. We propose an optimization-based computer- aided molecular design (CAMD) method to identify and select, from

We provide the open problems presented at OPSFA-13, Gaithersburg, Maryland, June 4, 2015. Howard Cohl, National Institute of Standards and Technology, has collected these open problems.

Using Category Theory to facilitate multiple manufacturing service database integration

July 20, 2016
Author(s)
Spencer J. Breiner, Albert T. Jones, David I. Spivak, Eswaran Subrahmanian, Ryan Wisnesky
The goal of this paper is to illustrate the use of category theory as a basis for the integration of manufacturing service databases. In this paper we use as our reference prior work by Kolvatunyu, et. al (2013) on the use of Ontology Web Language(OWL)

A STATISTICAL APPROACH TO ESTIMATING A 95 % CONFIDENCE LOWER LIMIT FOR THE DESIGN CREEP RUPTURE TIME VS. STRESS CURVE WHEN THE STRESS ESTIMATE HAS AN ERROR UP TO 2 % (*)

July 17, 2016

Jeffrey T. Fong, James J. Filliben, Nathanael A. Heckert, Pedro V. Marcal, Marvin J. Cohn
Recent experimental results on creep-fracture damage with minimum time to failure (minTTF) varying as the 9th power of stress, and a theoretical consequence that the coefficient of variation (CV) of minTTF is necessarily 9 times that of the CV of the

Advancing X-Ray Scattering Metrology Using Inverse Genetic Algorithms

July 7, 2016
Author(s)
Adam F. Hannon, Daniel F. Sunday, Donald A. Windover, Regis J. Kline
We compare the speed and effectiveness of two genetic optimization algorithms to the results of statistical sampling via a Markov Chain Monte Carlo algorithm to find which is the most robust method for determining real space structure in periodic gratings

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016
Author(s)
Felipe F. Lopez, Paul Witherell, Brandon Lane
A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced

Vibrational Modes of Multilayered Ceramic Capacitors

April 28, 2016
Author(s)
Kirsten L. Peterson, Ward L. Johnson, Sudook A. Kim, Paul R. Heyliger
Micron-scale spacing of interleaved electrodes and high-dielectric ceramics in multilayer ceramic capacitors (MLCCs) provide exceptionally high capacitances in small volumes. This has led to MLCCs being the preferred type of capacitor in a wide range of
