71. Simplified Design Procedure for Hybrid Precast Concrete Connections
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 5765
Published: 2/1/1996
Authors: Geraldine S Cheok, William C Stone, S. D. Nakaki
Abstract: A rational design procedure is presented to compute the probable moment, the nominal moment, and the story drift capacities of a hybrid precast moment-resisting beam-to-column connection. The hybrid connections consist of mild steel which is used to ...

72. Some Issues Relating to Performance Evaluation of LADARs
Published: 9/16/2003
Authors: Geraldine S Cheok, William C Stone, Christoph Johann Witzgall
Abstract: The use and scope of LADAR applications continues to expand as the technology matures. This growth is reflected in NIST's experience with research into the applications of LADARs for construction, manufacturing, and autonomous vehicle navigation. How ...

73. Standard Test Procedures and Metrics Development for Automated Guided Vehicle Safety Standards
Published: 5/23/2012
Authors: Roger V Bostelman, William P Shackleford, Geraldine S Cheok, Richard J Norcross
Abstract: The National Institute of Standards and Technology's Intelligent Systems Division has been researching automated guided vehicle (AGV) control based on advanced two-dimensional (2D) imaging sensors that detect dynamic, standard test pieces represent ...

74. Standards Requirements for LADARs?
Published: 1/1/2005
Authors: Geraldine S Cheok, William C Stone, Alan M. (Alan M.) Lytle
Abstract: This paper presents a discussion of standards requirements for LADAR. Two specific questions are addressed: (1) is there a need for such standards and (2) what types of standards are required? LADAR standards development issues and current standard ...

75. Status of the NIST 3D Imaging System Performance Evaluation Facility
Published: 1/1/2006
Authors: Geraldine S Cheok, Alan M. (Alan M.) Lytle, Kamel S Saidi
Abstract: This paper will present the status of the indoor artifact-based Performance Evaluation Facility at the National Institute of Standards and Technology (NIST) for 3D imaging systems. This facility will be used to develop test protocols and performance ...

76. Summary of NIST s Efforts to Develop Protocols for the Performance Evaluation of 3D Imaging Systems
Published: Date unknown
Authors: Geraldine S Cheok, Alan M. (Alan M.) Lytle, Kamel S Saidi
Abstract: A synopsis of the effort at the National Institute of Standards and Technology (NIST) to develop standard protocols for the performance evaluation of 3D Imaging Systems is presented. A 3D imaging system is an instrument that is used to rapidly measu ...

77. Summary of the Structural Performance of Single-Family, Wood-Frame Housing
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6224
Published: 9/1/1998
Authors: Charles William Clay Yancey, Geraldine S Cheok, Fahim Sadek, B Mohraz
Abstract: A review of the structural performance of single-family, wood-frame houses is presented. The performance of these structures in selected earthquakes and hurricanes is summarized. In general, wood-frame houses performed well with relatively few inst ...

78. TIN Techniques for Data Analysis and Surface Construction
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7078
Published: 1/1/2004
Authors: Christoph Johann Witzgall, Javier Bernal, Geraldine S Cheok
Abstract: This report addresses the task of meshing point clouds by triangulated elevated surfaces referred to as TIN surfaces. It describes the general features of this approach, and refers to prototype TIN software employed at NIST for research into the ana ...

79. Target Penetration of Laser-Based 3D Imaging Systems
Published: 1/19/2009
Authors: Geraldine S Cheok, Kamel S Saidi, Marek Franaszek
Abstract: The ASTM E57.02 Test Methods Subcommittee is developing a test method to evaluate the ranging performance of a 3D imaging system. The test method will involve either measuring the distance between two targets or between an instrument and a target. Th ...

80. Techniques to Evaluate Laser Scanners for Advanced Manufacturing Applications
Published: 7/23/2015
Authors: Prem K Rachakonda, Balasubramanian Muralikrishnan, Katharine M Shilling, Daniel S Sawyer, Geraldine S Cheok, Kamel S Saidi
