Ram D. Sriram, Steven J. Fenves
Health care informatics deals with all the processes or "software" of the health care enterprise: modeling, design, simulation and implementation of health care information systems, support and control of manufacturing and its associated supply chains, and

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

Towards Information Networks to Support Composable Manufacturing

October 15, 2008
Author(s)
Mahesh Mani, Albert W. Jones, Jun H. Shin, Ram D. Sriram
Rigid, supply-chain organizational structures are giving way to highly dynamic collaborative partnerships. These partnerships will develop rapidly by composing global manufacturing resources in response to open market opportunities; and, they will disband

Extending the Notion of Quality from Physical Metrology to Information and Sustainability

July 30, 2008
Author(s)
Gaurav Ameta, Sudarsan Rachuri, Xenia Fiorentini, Mahesh Mani, Steven J. Fenves, Kevin W. Lyons, Ram D. Sriram
In this paper we intend to demonstrate the need for extending the notion of quality from the physical domain to information and, more comprehensively, to sustainability. In physical metrology there are well established principles such as fundamental units

Introducing Sustainability Early into Manufacturing Process Planning

May 7, 2008
Author(s)
Mahesh Mani, Kevin W. Lyons, Sudarsan Rachuri, Eswaran Subrahmanian, Ram D. Sriram
In response to the global trend towards implementing sustainable manufacturing practices, we put forth an exploratory approach that uses energy monitoring as a means to introduce sustainability criteria early into manufacturing process planning and

Content-Based Assembly Search: A Step Towards Assembly Reuse

November 7, 2007
Author(s)
Ram D. Sriram, A S. Deshmukh, A G. Banerjee, Satyandra K. Gupta
The increased use of CAD systems by product development organizations has resulted in the creation of large databases of assemblies. This explosion of assembly data is likely to continue in the future. In many situations, text-based search alone may not be

Standardized Data Exchange of CAD Models with Design Intent

September 1, 2007
Author(s)
Junhwan Kim, Mike Pratt, Raj G. Iyer, Ram D. Sriram
Modern CAD systems generate feature-based product shape models with parameterization and constraints. Until recently, standards for CAD data exchange among different CAD systems were restricted to the exchange of pure shape information. These standards

Data Exchange of Parametric CAD Models Using ISO 10303-108

July 1, 2007
Author(s)
Junhwan Kim, Mike Pratt, Raj G. Iyer, Ram D. Sriram
Modern CAD systems generate feature-based product shape models with parameterization and constraints. Until recently, standards for CAD data exchange among different CAD systems were restricted to the exchange of pure shape information. These standards

The Architecture Development Facilitator (ADF) First Year Report

March 1, 2007
Author(s)
Steven J. Fenves, Eswaran Subrahmanian, Puja Goyal, Jean-Cyrus L. Angbo, Faouzi Daoud, Ram D. Sriram
This document serves as the summary report on the first year?s progress on the Architecture Development Facilitator (ADF) project covering the activities from December 15, 2005, to December 15, 2006. The ADF is intended to assist the Office of Network

A Model of Deformable Rings for Interpretation of Wireless Capsule Endoscopic Videos

November 1, 2006
Author(s)
Piotr Szczypinski, Ram D. Sriram, Parupudi Sriram, Nageshwar Reddy
Wireless Capsule Endoscopy (WCE) provides a means to obtain a detailed video of the small intestine, not feasible with other endoscopic techniques. A single session with WCE may produce nearly 8 hours of video, which may take around one to two hours to

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

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

Special Issue on Collaborative Engineering

June 1, 2006
