101. Measuring Performance and Intelligence of Intelligent Sytems White Paper 2001
Published: 8/4/2001
Authors: Elena R Messina, Alex Meystel, Larry H Reeker
Abstract: Is the measurement of performance for intelligent systems different than that of non-intelligent systems? In this white paper, we explore the various dimensions of evaluation of intelligence and performance. The main areas we tackle are the testing ...

102. A Feature-Based Inspection and Machining System
Published: 8/1/2001
Authors: Thomas Rollin Kramer, Hui-Min Huang, Elena R Messina, Frederick M Proctor, Harry A. Scott
Abstract: This paper describes an architecture for a system for machining and inspectingmechanical piece parts and an implementation of it called the Feature-BasedInspection and Control System (FBICS). In FBICS, the controller of a machiningcenter or coordinat ...

103. Analysis of Dimensional Metrology Standards
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6847
Published: 6/1/2001
Authors: Thomas Rollin Kramer, John Evans, Simon Paul Frechette, John A Horst, Hui-Min Huang, Elena R Messina, Frederick M Proctor, William G Rippey, Harry A. Scott, Theodore Vincent Vorburger, Albert J. Wavering
Abstract: This is an analysis of standards related to dimensional metrology, with recommendations regarding standards development. The analysis focuses on the degree to which existing and developing standards provide a complete set of non-overlapping specifica ...

104. Open System Architecture for Real-time Control Using an UML Based Approach
Published: 5/1/2001
Authors: Hui-Min Huang, Elena R Messina, Harry A. Scott, James S. Dr. Albus, Frederick M Proctor, William P Shackleford
Abstract: We describe a generic architecture that is applicable to the engineering of many real-time control problems. We further describe how UML is used to apply the architecture to the problems.

105. Report of the NIST MEL Architecture Task Force
Series: NIST Interagency/Internal Report (NISTIR)
Published: 12/29/2000
Authors: Harry A. Scott, John Evans, Steven R. Ray, E Clayton Teague, James S. Dr. Albus, Herbert T Bandy, Edward J Barkmeyer, Neil Christopher, M Alkan Donmez, Hui-Min Huang, Albert W Jones, Elena R Messina, Jim G Nell, Frederick M Proctor, Evan K Wallace
Abstract: The NIST Manufacturing Engineering Laboratory undertook a series of internal working meetings to examine all of its architecture efforts.  A survey of work was performed, and recommendations were identified.  This document, initially compil ...

106. A Standard Test Course for Urban Search and Rescue Robots
Published: 8/1/2000
Authors: Adam S Jacoff, Elena R Messina, John Evans
Abstract: One approach to measuring the performance of intelligent systems is to develop standardized or reproducible tests. These tests may be in a simulated environment or in a physical test course. The National Institute of Standards and Technology is dev ...

107. Performance Metrics for Intelligent Systems
Published: 8/1/2000
Authors: John Evans, Elena R Messina
Abstract: Research into intelligent systems and intelligent control is burgeoning. However, there is no consensus on how to define or measure an intelligent system. This lack of rigor hinders the ability to measure progress in the field and to compare differen ...

108. The NIST RS274NGC Interpreter - Version 3
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6556
Published: 8/1/2000
Authors: Thomas Rollin Kramer, Frederick M Proctor, Elena R Messina
Abstract: This report describes an interpreter which reads numerical control code and produces calls to a set of canonical machining functions. The interpreteris a software system written in the C++ programming language. The output of the interpreter may be us ...

109. The Challenge of Intelligent Systems
Published: 7/19/2000
Authors: A Meystel, Elena R Messina
Abstract: This paper analyzes the meaning of intelligence within the domain of intelligent control. Because of historical reasons, there are varying and diverse definitions of what constitutes an intelligent control system. Due to the multidisciplinary natu ...

110. An Open Architecture Inspection System
Published: 7/1/2000
Authors: Elena R Messina, Hui-Min Huang, Harry A. Scott
Abstract: The benefits of open architectures are not currently available for most manufacturing equipment. We describe a testbed for experimenting with an open architecture controller for an inspection system. An initial taxonomy of categories of openness ...
