A Model-Driven Approach for Building OWL DL and OWL Full Ontologies

October 1, 2006
Author(s)
S Brockmans, R Colomb, P Haase, E Kendall, Evan K. Wallace, G Xie
This paper presents an approach for visually modeling OWL DL and OWL Full ontologies based on the well-established visual modeling language UML. We discuss a metamodel for OWL based on the Meta-Object Facility, an associated UML profile as visual syntax

Interprocess Communication in the Process Specification Language

October 1, 2006
Author(s)
Conrad E. Bock
Interprocess communication is ubiquitous in modern computing, appearing most commonly as inputs, outputs, and messaging. This paper formalizes interprocess communication based on the involvement of entities in a process, and how processes determine which

Notes on an Information Model for Production Rules

October 1, 2006
Author(s)
Peter O. Denno
Production rules are rules used in production systems, sometimes called production rule engines. Production rule engines are commonly used to implement expert systems. This report describes an information model for the exchange of production rules and for

Simulation Prototypes for Incident Management Training

October 1, 2006
Author(s)
Guodong Shao, Charles R. McLean
First responders and incident management personnel need better training resources to prepare for future disasters. Live training exercises while valuable are often very expensive to organize and conduct. Training using modeling, simulation, and gaming

The Interface Development for Machine Shop Simulation

October 1, 2006
Author(s)
Yan Luo, Yung-Tsun T. Lee
Modeling and simulation technology is recognized for facilitating training, reducing production cost, improving product quality, and shortening development time. However, this technology remains largely underutilized by industry today. This is because

Parametric Uncertainty in Optical Image Modeling

September 18, 2006
Author(s)
James E. Potzick, Egon Marx, M P. Davidson
Optical photomask feature metrology and wafer exposure process simulation both rely on optical image modeling for accurate results. While it is fair to question the accuracies of the available models, model results also depend on several input parameters

A Study on Search Engine Use by Intelligence Analysts

September 1, 2006
Author(s)
Don E. Libes, Emile L. Morse, Jean C. Scholtz
This work reports on search engine use by intelligence analysts, generally considered experts at the task of searching for information. Intelligence analysts share a degree of common training and understanding while having widely differing backgrounds

Illumination Optimization for Optical Semiconductor Metrology

September 1, 2006
Author(s)
Bryan M. Barnes, L Howard, Richard M. Silver
Uniform sample illumination via K hler illumination, is achieved by establishing a pair of conjugate focal planes; a light source is focused onto the condenser lens aperture while the image of the field aperture is focused at the plane of the specimen

Message Validation with a Semantic Reasoning Tools

September 1, 2006
Author(s)
Peter O. Denno, Nenad Ivezic
This paper describes challenges encountered in the development of a tool to validate OASIS UBL-based (Universal Business Language) messages. The software tool is ontology-based, using first-order logic and parts of the Suggested Upper Merged Ontology (SUMO

Part-part Relations in an RDF/S and OWL Extension

September 1, 2006
Author(s)
Conrad E. Bock
This describes an extension to the Resource Description Framework/Schema (RDF/S) to specify relations between parts of the same whole (composite structure). For example, the relation between engine and wheels in a car applies in each individual car, rather

A Validation Architecture for Advanced Interoperability Provisioning

August 1, 2006
Author(s)
Nenad Ivezic, Edward J. Barkmeyer Jr., Boonserm Kulvatunyou, Albert W. Jones, Pat Snack, Zuran Marjanovic, Hyunbo Cho
We describe an architecture to validate new tools in support of interoperability provisioning processes that take place within industrial communities. We start from a best-practices standards development process where an industry community develops

An Infrastructure to Support Performance Analysis in Complex Systems

August 1, 2006
Author(s)
Man-Sze Li, A S. Deshmukh, Albert T. Jones
Systems research efforts have increased in a variety of disciplines. Despite these efforts, it is still difficult to predict long-term performance and to understand the relationship between the performance of the parts and the performance of the whole. The

Evaluating Suitability for Replacement of an Integrated Software Component

August 1, 2006
Author(s)
Boonserm Kulvatunyou, B Jeong, Hyunbo Cho, Nenad Ivezic, Albert W. Jones
An evaluation of the compatibility of a software component is based typically only on a vendor?s presentation. This means that end users select a software component only based on high-level matches of functional requirements. This can result in an

Feature Technology and Ontology for Embedded System Design and Development

August 1, 2006
Author(s)
XuanFang Zha, Ram D. Sriram
In this paper, we present our recent effort on using a feature technology and ontology for embedded systems modeling and design. We present an overview of embedded system design and propose an object-oriented UML modeling approach to representing embedded

NIST Calibration Services for Water Flowmeters Water Flow Calibration Facility

August 1, 2006
Author(s)
Iosif I. Shinder, Iryna V. Marfenko
This document describes the Water Flow Calibration Facility (WFCF) at the National Institute of Standards and Technology (NIST). This facility has three parallel pipelines with diameters of 100, 200 and 400 mm and three weighing systems with capacities of

The Evaluation of Ontologies

August 1, 2006
Author(s)
Leo Obrst, Benjamin Ashpole, Werner Ceusters, Mahesh Mani, Steven R. Ray, Bradford Smith
Recent years have seen rapid progress in the development of ontologies as semantic models intended to capture and represent aspects of the real world. There is, however, great variation in the quality of ontologies. If ontologies are to become

Probe-Based Micro-Scale Manipulation and Assembly Using Force Feedback

June 26, 2006
Author(s)
Jason J. Gorman, Nicholas Dagalakis
Repeatable manipulation and assembly of micro-scale components is a critical capability for future developments in opto-electronics, hybrid microelectromechanical systems, and the integration of nano-scale devices into larger systems. This paper focuses on

A Web Service-Based Reconfigurable Testbed for Business-to-Business (B2B) Integration

June 1, 2006
Author(s)
B Jeong, Jungyub Woo, Hyunbo Cho, Boonserm Kulvatunyou, James Lee
Several types of standards and corresponding software solutions have been created to enable business-to-business (B2B) integration. Testing for conformance and interoperability among these solutions are inter-dependent. This signifies the needs to make
