61. Choosing test positions for laser tracker evaluation and future Standards development
Topic: Metrology
Published: 7/15/2010
Authors: Balasubramanian Muralikrishnan, Daniel S Sawyer, Christopher J Blackburn, Steven David Phillips, Craig M Shakarji, Ed Morse, Robert Bridges
Abstract: A working group within the ISO TC 213 committee is developing a draft document [11] for evaluating the performance of laser trackers. The ASME B89.4.19 Standard [1] and the draft VDI/VDE 2617 part 10 [2] describe some useful tests that are incorporat ...

62. Cylindrical Acoustic Resonator for the Re-determination of the Boltzmann Constant
Topic: Metrology
Published: 6/1/2010
Authors: J.T. Zhang, H. Lin, X.J. Feng, Keith A Gillis, Michael R Moldover
Abstract: We describe progress towards re-determining the Boltzmann constant {I}k{/I}^dB^ using two fixed-path, gas-filled, cylindrical, acoustic cavity resonators. The longitudinal acoustic resonance modes of a cylindrical cavity have lower quality factors {I ...

63. Feasibility of an Accurate Dynamic Standard for Water Flow
Topic: Metrology
Published: 6/1/2010
Authors: Iosif I Shinder, Michael R Moldover
Abstract: We used NIST's primary water flow standard to study the feasibility of accurately determining mass flow rates {I}m{/I}^ddot^ of water "dynamically," that is from the time derivative of the weight {I}W{/I} of the collection tank: {I}m{/I ...

64. Performance of Critical Flow Venturis under Transient Conditions
Topic: Metrology
Published: 4/13/2010
Author: John D Wright
Abstract: Critical flow venturis (CFVs) can be used to measure flow under transient pressure and flow conditions with uncertainties of 0.13 % or less (95 % confidence level). Blow-down tests transferred 630 g of nitrogen during a 100 s interval from an unregul ...

65. The Limits and Extensibility of Optical Patterned Defect Inspection
Topic: Metrology
Published: 4/1/2010
Authors: Richard M Silver, Bryan M Barnes, Martin Y Sohn, Richard Quintanilha, Hui Zhou, Chris Deeb, Mark Johnson, Milton Goodwin, Dilip Patel
Abstract: New techniques recently developed at the National Institute of Standards and Technology using bright field optical tools are applied to signal-based defect analysis of features with dimensions well below the measurement wavelength. A key to this app ...

66. DYNAMIC PERCEPTION WORKSHOP REPORT: Requirements and Standards for Advanced Manufacturing
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7664
Topic: Metrology
Published: 1/14/2010
Authors: Tsai Hong Hong, Elena R Messina, Hui-Min Huang, Michael O Shneier, Roger D. Eastman, Jane Shi, James Wells
Abstract: The Dynamic Perception workshop was intended to further the development of standardized, reproducible, and portable test methods that can advance the technology of sensors and perception systems for new, flexible robotic and automation applications i ...

67. Performance Evaluation and Metrics for Perception in Intelligent Manufacturing
Topic: Metrology
Published: 12/31/2009
Authors: Roger D. Eastman, Tsai Hong Hong, Jane Shi, Tobias Hanning, Balasubramanian Muralikrishnan, S. Susan Young, Tommy Chang
Abstract: Real-time three-dimensional vision has been rapidly advancing over the past twenty years, leading to a number of successful laboratory demonstrations, including real-time visual servoing, autonomous vehicle navigation , and real-time people and vehic ...

68. Interoperability and the DMIS experience
Topic: Metrology
Published: 10/30/2009
Author: John A Horst
Abstract: Because they enable true interoperability, information exchange standards can help manufacturers reduce cost and improve product quality, but only if the standards are developed and implemented correctly. We will answer questions manufacturers and su ...

69. Mathematical Metrology for Evaluating a 6DOF Visual Servoing System
Topic: Metrology
Published: 10/8/2009
Authors: Tommy Chang, Tsai Hong Hong, Milli Shah, Roger D Eastman
Abstract: In this paper we develop the best homogeneous matrix trans- formation to fit two streams of dynamic six-degree-of-freedom (6DOF) data for evaluating perception systems using ground truth. In particular, we compare object position and orien- tation re ...

70. Influence of room temperature control system on AFM imaging
Topic: Metrology
Published: 10/1/2009
Authors: Joseph Fu, Wei Chu, Theodore Vincent Vorburger
Abstract: As technology progresses, the control of environment for experiments is also getting more sophisticated; such as the control of lab temperature and vibration. Temperature controlled within ± 0.25° C for a general purpose lab is common place. We illus ...
