Field Standards for Weights and Measures

April 1, 2013
Author(s)
Georgia L. Harris
An article written for the measurement community on whether [field] standards are “fit for purpose”. Is the equipment used is in testing designed for the purpose in which it is being used. The concept of fit for purpose is common in method validation

Logic Minimization Techniques with Applications to Cryptology

April 1, 2013
Author(s)
Joan Boyar, Philip Matthews, Rene Peralta
A new technique for combinational logic optimization is described. The technique is a two-step process. In the rst step, the non-linearity of a circuit as measured by the number of non-linear gates it contains is reduced. The second step reduces the number

Path aggregation techniques for EXAFS visualization and analysis

April 1, 2013
Author(s)
Bruce Ravel
The path expansion model used by feff considers the EXAFS spectrum as the sum of contributions from scattering geometries of two or more atoms in a cluster surrounding the absorbing atom. This model and its representation as a collection of les is the

Performance Evaluation of High-Strength Steel Pipelines for High-Pressure Gaseous Hydrogen Transportation

April 1, 2013
Author(s)
Andrew J. Slifka, Elizabeth S. Drexler, Robert L. Amaro, Joseph D. McColskey, Yaoshan Chen, Ming Liu, Yong-Yi Wang
Pipeline steels suffer significant degradation of their mechanical properties in high-pressure gaseous hydrogen, including their fatigue cracking resistances to cyclic loading. Fatigue crack growth experiments were performed on X52 and X70 steels in both

Performance Metrics of Speed and Separation Monitoring in Shared Workspaces

April 1, 2013
Author(s)
Jeremy A. Marvel
A metric is proposed that evaluates speed and separation monitoring efficacy in industrial robot environments in terms of the quantification of safety and the effects on productivity. The collision potential is rep-resented by separation metrics and sensor
