131. Collaborating on the Design and Manufacture of an Atomic Artifact Transport System: A Case Study in VRML as a Visualization Tool for Consensus Building
Published: 9/1/1998
Authors: Robert Allen, Srinivas Nidamarthi, P V Rao, Richard L. Rhorer, Ram D Sriram, E Clayton Teague
Abstract: We report on our experience using the Virtual Reality Markup Language (VRML) to collaborate on the design and manufacture of an artifact transport system (ATS). Specifically designed for the purpose of transporting nanometer-scale dimensional artifac ...

132. Internet-Based Delivery of CAD/CAM Capability: An Industry Case Study
Published: 9/1/1998
Authors: Simon Szykman, Ram D Sriram
Abstract: This paper presents a case study in the use of the Internet as a medium for exchange of information and delivery of computer-aided design and computer-aided manufacturing (CAD/CAM) capability. The case study describes collaboration among researchers ...

133. The NIST Design/Process Planning Integration Project
Published: 9/1/1998
Authors: Walter W Nederbragt, Robert Allen, Shaw C Feng, Serge Kaing, Ram D Sriram, Yuyun Zhang
Abstract: This paper presents a description of the National Institute of Standards and Technology (NIST) Design/Process Planning Integration (DPPI) Project, which addresses the need for improving communications between design and process planning activities. ...

134. Towards STEP-Based Data Transfer in Layered Manufacturing
Published: 9/1/1998
Authors: D Dutta, Anil Kumar, Mike Pratt, Ram D Sriram
Abstract: This paper concerns the informational requirements of layered manufacturing (LM). The most common industrial use of LM today is for rapid prototyping, but we take a wider view of it as a flexible fabrication technology. Its use in building functional ...

135. An Object-Oriented Representation for Product and Design Processes
Published: 7/1/1998
Authors: Ram D Sriram, S Gorti, A Gupta, Gerard Kim, A Wong
Abstract: We report on the development of a knowledge representation model, which is based on the SHARED object model reported in [33,34]. Our current model is implemented as a layered scheme, that incorporates both an evolving artifact and its associated des ...

136. An Information Modeling Framework to Support Design Databases and Repositories
Published: 9/1/1997
Authors: J i Murdock, Simon Szykman, Ram D Sriram
Abstract: The paper introduces an information modeling framework to support representation of design artifacts for design databases and repositories. While most artifact representations consist primarily of geometric information, the object oriented design m ...

137. From Symbol to Form: A Framework for Conceptual Design
Published: 1/1/1997
Authors: S Gorti, Ram D Sriram
Abstract: This paper presents the design of a software framework for conceptual design. It develops an approach to mapping an evolving symbolic description of design into a geometric description. The distinct elements of the symbol-form mapping are (a)deriving ...

138. An Object-oriented Representation of Product and Design
Published: 8/1/1996
Authors: Gerard Kim, S Gorti, A Gupta, A Wong, Ram D Sriram
Abstract: We introduct a representation scheme for engineering design synthesis that includes not only a way to represent an evolving attifact but also the design process. The representation uses an object-oriented approach in order to model a wide range of de ...

139. Overview and Vision of the NIST Engineering Design Technologies Group
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5827
Published: 1/1/1996
Author: Ram D Sriram
Abstract: The NIST Manufacturing Systems Integration Division established the Engineering Design Technologies (EDT) Group to address the critical design needs of U.S. industry. The vision of the EDT group is to be a world leader in the development of technolog ...

140. SIMA Reference Architecture Part I: Activity Models
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5939
Published: 7/1/1987
Authors: Edward J Barkmeyer, Neil Christopher, Shaw C Feng, James E. Fowler, Simon Paul Frechette, Albert W Jones, Kevin K Jurrens, Charles R. McLean, Mike Pratt, Harry A. Scott, M. Kate Senehi, Ram D Sriram, Evan K Wallace
Abstract: This report describes the activities and information flows inherent in the product realization process for discrete electro-mechanical parts and products. That is, it describes the technical functions which must be performed to take a part/product f ...
