A Framework for Research Inventory of Manufacturing Sustainability Assessment

May 19, 2014
Author(s)
Juyeon Lee, Yung-Tsun T. Lee
There have been many research papers focused on development of guidelines, indicators, metrics, methods, tools, and systems – all related to sustainability performance assessment. However, manufacturing companies have difficulty in finding papers that are

AN INTEGRATED APPROACH TO INFORMATION MODELING FOR THE SUSTAINABLE DESIGN OF PRODUCTS

May 19, 2014
Author(s)
Paul W. Witherell, Douglas Eddy, Ian Grosse, Sundar Krishnamurty, Jack Wileden, Kemper Lewis
The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support

Geometric Interoperability via Queries

May 19, 2014
Author(s)
Vijay Srinivasan
The problem of geometric (model and system) interoperability is a non-trivial generalization of the classical problem of part interchangeability in mechanical assemblies. Interoperability subsumes the challenging problems of geometric model quality

Ontological Conceptualization Based on Simple Knowledge Organization System (SKOS)

May 19, 2014
Author(s)
Nenad Ivezic, Ameri Farhad, Kaikhah Khosrow, Boonserm Kulvatunyou
In this paper, a thesaurus-based methodology is proposed for systematic ontological conceptualization in the manufacturing domain. The methodology has three main phases, namely, thesaurus development, thesaurus evaluation, and thesaurus conversion. A

Processes Analytics Formalism for Decision Guidance in Sustainable Manufacturing

May 19, 2014
Author(s)
Alexander Brodsky, Guodong Shao, Frank H. Riddick
This paper introduces National Institute of Standards and Technology (NIST)'s Sustainable Process Analytics Formalism (SPAF) to facilitate the use of simulation and optimization technologies for decision support in sustainable manufacturing. SPAF allows

The Case for Delivering the Infrastructure for Digital Building Regulations

May 19, 2014
Author(s)
Mark E. Palmer, James H. Garrett
The building industry uses numerous engineering standards, building codes, specifications and regulations and a diverse set of industry vocabularies to describe, assess, and deliver constructed facilities. As part of the expanding use of building

Towards More Effective Spectrum Test

May 16, 2014
Author(s)
Alan D. Skillicorn, Michael H. Kelley, Thomas J. Taylor, Eric Nelson
In response to the Presidential Memorandum on Wireless Innovation and the recommendation of the Presidential Council of Advisors on Science and Technology (PCAST), the federal government has begun the process of organizing a National Advanced Spectrum and

Characterization of Emissions from Spray Polyurethane Foam: Letter Report to U.S. Consumer Product Safety Commission Interagency Agreement CPSC-I-13-0016

May 15, 2014
Author(s)
Dustin G. Poppendieck, Matthew P. Schlegel, Andrew K. Persily, Steven J. Nabinger
This letter report provides a project update reflecting the activities to date under the FY2013 interagency agreement between CPSC and NIST. The objective of that agreement is to develop testing and measurement protocols for determining the quantities and

Guidelines on Mobile Device Forensics

May 15, 2014
Author(s)
Richard Ayers, Sam Brothers, Wayne Jansen
Mobile device forensics is the science of recovering digital evidence from a mobile device under forensically sound conditions using accepted methods. Mobile device forensics is an evolving specialty in the field of digital forensics. This guide attempts

LTE Physical Layer Performance Analysis

May 15, 2014
Author(s)
Wen-Bin Yang, Michael R. Souryal
In this report, we present results of a physical layer performance study for all MCSs (from MCS0 to MCS28) in terms of block error rate (BLER) and spectral efficiency. The results are obtained by using the Steepest Ascent LTE toolbox for MATLAB which

Non-contact Conductance Measurement of Nanosize Objects using Reasonant Cavity

May 15, 2014
Author(s)
Jan Obrzut, Nathan D. Orloff, Oleg A. Kirillov
A cavity perturbation method is used to determine conductance of small volume nano-carbon materials. These are the building blocks of nanostructured materials and devices, and therefore their electrical characteristics are important in the materials

Standards in Biothermodynamics

May 15, 2014
Author(s)
Robert N. Goldberg
The field of biothermodynamics encompasses physical property measurements on biochemical and biological systems. This chapter reviews the status of standards documents that are pertinent to biothermodynamics as well as recommendations that have been made

A Facile Route to the Synthesis of Monodisperse Nanoscale Liposomes Using 3D Microfluidic Hydrodynamic Focusing in a Concentric Capillary Array

May 14, 2014
Author(s)
Wyatt N. Vreeland, Renee R. Hood, Don L. DeVoe, Francisco J. Atencia, Donna M. Omiatek
A novel microscale device has been developed to enable the one-step continuous flow assembly of monodisperse nanoscale liposomes using three-dimensional microfluidic hydrodynamic focusing (3D-MHF) in a radially symmetric capillary array. The 3D-MHF flow

Effect of Interfacial Octahedral Behavior in Ultrathin Manganite Films

May 14, 2014
Author(s)
E. J. Moon, P. V. Balachandran, Brian Kirby, D.J. Keavney, R.J. Sichel-Tissot, C. M. Schleputz, E. Karapetrova, X. M. Cheng, James M. Rondinelli, S. J. May
We investigate structural coupling of the MnO 6 octahedra across a film/substrate interface and the resultant changes of the physical properties of ultrathin La 2/3}Sr 1/3}MnO 3 (LSMO) films. In order to isolate the effect of interfacial MnO 6 octahedral

Packing density of rigid aggregates is independent of scale

May 14, 2014
Author(s)
Christopher D. Zangmeister, James G. Radney, Michael R. Zachariah
Large planetary seedlings, comets, microscale pharmaceuticals, and nanoscale soot particles are made from rigid, aggregated subunits that are compacted under low compression into larger structures spanning over 10 orders of magnitude in dimensional space
