Loading Protocols for ASCE 41 Backbone Curves

November 1, 2016
Author(s)
Bruce F. Maison, Matthew Speicher
ASCE 41-13 is an industry standard for seismic evaluation and retrofit of existing buildings. Alternative component modeling and acceptance criteria are based on a backbone curve constructed from an envelope of component hysteresis loops derived via

Modeling the Internet of Things and People: A Foundational Approach

Spencer J. Breiner, Eswaran Subrahmanian, Ram D. Sriram
As we extend the reach of the Internet through sensing and automation, networked systems interact more and more of our daily lives, requiring much greater sensitivity to social networks and greater robustness in the face of human behavior. A tremendous

Abstract: A comparison of terahertz (THz) laser power measurements was undertaken among three national metrology institutes. At two THz frequencies, 2.52 THz (119 µm) and 0.762 THz (394 µm), a power level of approximately 3 mW was compared at one place at

CORRELATIONS AMONG ACOUSTIC MEASUREMENTS OF THE BOLTZMANN CONSTANT

September 9, 2015
Author(s)
Michael R. Moldover, Roberto M. Gavioso, David B. Newell
We review correlated uncertainties among the accurate determinations of the Boltzmann constant kB that used the techniques of primary acoustic gas thermometry (AGT). We consider uncertainty contributions from four sources: (1) resonator-dependent

Performance Measurement of Mobile Manipulators

April 24, 2015
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Jeremy A. Marvel
This paper describes a concept for measuring the reproducible performance of mobile manipulators to be used for assembly or other similar tasks. An AGV with an onboard robot arm was programmed to repeatedly move to and stop at a novel, reconfigurable
