The Impact-Echo Method: An Overview

Author(s)
Nicholas J. Carino
The impact-echo method is a technique for flaw detection in concrete. It is based on monitoring the surface motion resulting from a short-duration mechanical

The Maturity Method: From Theory to Application

Author(s)
Nicholas J. Carino, Hai S. Lew
The maturity method is a technique to account for the combined effects of time and temperature on the strength development of concrete. The method provides a

Impact of Model-Driven Architecture

Author(s)
David W. Flater
The Object Management Group (the consortium that issues the Common Object Request Broker Architecture and Unified Modeling Language standards) is making the

Towards a Traceable Nanoscale Force Standard

Author(s)
Jon R. Pratt, David B. Newell, Edwin R. Williams, Douglas T. Smith, John A. Kramar
The National Institute of Standards and Technology has launched a five-year project to traceably link the International System of Units (SI) to forces between

The Electronic Kilogram

Author(s)
Michael H. Kelley
The kilogram is the only remaining base unit in the International System of Units (SI) whose definition is based on a single physical artifact rather than on

Reconfigurable Machine Controllers using the OMAC API

Author(s)
S Birla, D -. Faulkner, John L. Michaloski, S -. Sorenson, G Weinert, James H. Yen
With enterprises facing tremendous time-to-market pressures, manufacturing systems must be implemented quickly and modified easily. The ability of the open

Mode-Locked Erbium/Ytterbium Co-Doped Waveguide Laser

Author(s)
John B. Schlager, Berton Callicoatt, Kevin L. Silverman, Richard Mirin, Norman Sanford, D. L. Veasey
Picosecond pulses are generated from a passively mode-locked ER3+/Yb3+ co-doped planar waveguide laser in an extended cavity configuration with a semiconductor

A Method to Compare Vector Nonlinear Network Analyzers

Author(s)
Kate Remley, Donald C. DeGroot, Jeffrey Jargon, Kuldip Gupta
We address the difficult problem of determining measurement consistency between two vector nonlinear network analyzers, a new class of stimulus-response

Calibrating Electro-Optic Sampling Systems

Author(s)
Dylan Williams, Paul D. Hale, Tracy S. Clement, Juanita M. Morgan
We apply frequency-domain impedance mismatch corrections to a temporal electro-optic sampling system. We identify and evaluate additional sources of measurement
