Development Life Cycle for Semantically Coherent Data Exchange Specification

December 1, 2008
Author(s)
Boonserm Kulvatunyou, Katherine C. Morris, Simon P. Frechette
In enterprise integration, a data-exchange specification is an architectural artifact that evolves along with the business. Maintaining a coherent, data-exchange, semantic model is an important, yet non-trivial task. A coherent, semantic model of data-

An Evaluation of Description Logic for the Development of Product Models

November 10, 2008
Author(s)
Xenia Fiorentini, Sudarsan Rachuri, Hyo Won Suh, Jae H. Lee, Ram D. Sriram
The languages and logical formalisms developed by information scientists and logicians concentrate on the theory of languages and logical theorem proving. These languages, when used by domain experts to represent their domain of discourse, most often have

User's Guide for the Quality of Design Testing Tool and the Content Checker

November 5, 2008
Author(s)
Katherine C. Morris, Simon P. Frechette, Puja Goyal, Joshua Lubell, Boonserm Kulvatunyou, Salifou Sidi Malick, Nicolas Brayard, Severin Tixier
This document describes the operation and usage of the Quality of Design and the Content Checker Testing Tools. These tools were developed at the National Institute of Standards and Technology (NIST) to support people in developing standards for the

Scanning Probe Microscopy for Dielectric and Metal Characterization

June 10, 2008
Author(s)
Joseph J. Kopanski, Thomas R. Walker
The properties of both insulators and metals can be characterized capacitively with scanning probe microscopy, though the techniques employed are different. Intermittent contact scanning capacitance microscopy (IC-SCM) is a useful technique for

Understanding EuP and REACH

June 10, 2008
Author(s)
John V. Messina, Eric D. Simmon
There has been a world-wide trend towards legislation meant to encourage sustainable manufacturing and minimize the environmental impact of product manufacturing. In the global economy, with its distributed supply chain, local environmental laws may affect

Understanding the IPC 175X Data Model

May 1, 2008
Author(s)
Eric D. Simmon, John V. Messina
More and more political bodies (countries, states, and unions) are enacting legislation designed to protect the environment from the impact of manufacturing. One category of restrictive legislation is called Extended Producer Responsibilities (EPR). The

THE FAST INITIAL THRESHOLD VOLTAGE SHIFT: NBTI OR HIGH-FIELD STRESS

April 27, 2008
Author(s)
Jason P. Campbell, Kin P. Cheung, John S. Suehle
Recent 'NBTI' studies have come to involve very high electric fields, yet these same studies are used to criticize the lower field 'NBTI' models. This study examines both high- and low-field degradation phenomena by monitoring the initial threshold voltage

Information management for Environmental Concerns

February 8, 2008
Author(s)
Eric D. Simmon, John V. Messina, Kevin G. Brady
Around the world there is a growing awareness that the environmental impact from manufacturing needs to be minimized. Concerns about issues from toxic materials ending up in landfills to manufacturing process chelmicals causing health problems are causing

Sustaining Engineering Informatics: Toward Methods and Metrics for Digital Curation

September 1, 2007
Author(s)
Joshua Lubell, Eswaran Subrahmanian, Mahesh Mani, Sudarsan Rachuri
Ensuring the long-term usability of engineering informatics (EI) artifacts is a challenge, particularly for products with longer life cycles than the computing hardware and software used for their design and manufacture. Addressing this challenge requires

Collaborative Augmented Reality for Better Standards

August 15, 2007
Author(s)
Matthew L. Aronoff, John V. Messina
Concurrent engineering depends on clear communication between all members of the development process. As that communication becomes more and more complex -- including not only textual descriptions, but CAD models, diagnostic data, process control data, and

An Ontology for Assembly Representation

July 1, 2007
Author(s)
Xenia Fiorentini, Iacopo Gambino, V.C. Liang, Sebti Foufou, Sudarsan Rachuri, Mahesh Mani, Conrad E. Bock
Mechanical assemblies are systems composed of modules that are either subassemblies or parts. Traditionally an assembly information model contains information regarding parts, their relationships, and its form. But it is important that the model also

Representation of Heterogeneous Material Properties in the Core Product Model

June 1, 2006
Author(s)
Arpan Biswas, Steven J. Fenves, V Shapiro, Ram D. Sriram
The Core Product Model (CPM) was developed at NIST as a high level abstraction for representing product related information, to support data exchange, in a distributive and a collaborative environment. In this paper, we extend the CPM to components with

SysML and UML 2 Support for Activity Modeling

June 1, 2005
Author(s)
Conrad E. Bock
This article describes activity modeling as specified by the Systems Modeling Language (SysML) and the finalization of the Unified Modeling Language version 2 (UML 2). It reviews and updates an earlier proposed alignment between Enhanced Functional Flow

PSL: A Semantic Domain for Flow Models

May 1, 2005
Author(s)
Conrad Bock, Michael Gruninger
Flow models underlie popular programming languages and many graphical behavior specification tools. However, their semantics is typically ambiguous, causing miscommunication between modelers and unexpected implementation results. This article introduces a

Systems Engineering in the Product Lifecycle

May 1, 2005
Author(s)
Conrad E. Bock
This article introduces basic elements of systems engineering that are useful in managing the product lifecycle, as expressed in an extension to the Unified Modeling Language. Models are described for product requirements in textual and computable form

Workflow Automation in a B2B Web-Portal Testbed

February 10, 2004
Author(s)
Marjane Mabrouk, Frederic J. de Vaulx, Tom Rhodes
The work described in this report, focused on specifying and managing different steps of a Business-to-Business (B2B) workflow by developing and integrating a Workflow Management System (WMS) within the NIST B2B Web-portal. This allows us to manage the

UML Without Pictures

August 1, 2003
Author(s)
Conrad E. Bock
This article reviews the primary concepts of repository-centered development with the Unified Modeling Language, explaining the relation between notation, semantics, and model compilation. It highlights UML's approach to semantics, and flexibility in

Initial Graphics Exchange Specification Volume 2: Application Protocols
