Development of an Ultra-Pure, Carrier-Free 209Po Solution Standard

July 23, 2015
Author(s)
Ronald Colle, Ryan P. Fitzgerald, Lizbeth Laureano-Perez
Ultra-pure, carrier-free 209Po solution standards have been prepared and standardized for their massic alpha-particle emission rate. The standards, which will be disseminated by the National Institute of Standards and Technology (NIST) as Standard

SIMULATION-BASED DESIGN CONCEPT EVALUATION FOR AMBULANCE PATIENT COMPARTMENTS

July 14, 2015
Author(s)
Deogratias Kibira, Yung-Tsun T. Lee, Jennifer L. Marshall, Allison Barnard Feeney, Larry Avery, Allie Jacobs
To address the inadequacy of existing standards regarding interior layout design, the Department of Homeland Security (DHS) Science and Technology Directorate, the National Institute of Standards and Technology (NIST), the National Institute for

Software Tools for XML to OWL Translation

July 7, 2015
Author(s)
Thomas Kramer, Benjamin H. Marks, Craig I. Schlenoff, Stephen B. Balakirsky, Zeid Kootbally, Anthony Pietromartire
This paper describes a set of closely related C++ software tools for manipulating XML (eXtensible Markup Language) schemas and XML instance files and translating them into OWL (Web Ontology Language) class _les and OWL instance files. They include: (1) an

Using Check Standard Data to Simplify Uncertainty Estimates

July 1, 2015
Author(s)
Theodore D. Doiron
Uncertainty has proven difficult to implement in calibrations labs. The subject has mathematics and statistics that are part of normal scientific research but are seldom found among working metrologists in small calibration labs. There is, however, a

Preface: Special Issue on Knowledge Driven Robotics and Manufacturing

June 30, 2015
Author(s)
Craig I. Schlenoff, Stephen B. Balakirsky, Edson Prestes
State-of-the-art robots are capable of sub-millimeter movement accuracy. However, they are often programmed by an operator using crude positional controls from a teach pendent. Reprogramming these robots when their task is altered requires that the robot

Cloud-Enabled Prognosis for Manufacturing

June 22, 2015
Author(s)
Robert Gao, Lihui Wang, Roberto Teti, David Dornfeld, Soundar Kumara, Masahiko Mori, Moneer Helu
Advanced manufacturing depends on the timely acquisition, distribution, and utilization of information from machines and processes across spatial boundaries for improved accuracy and reliability in predicting resource needs and allocation, maintenance

A Generalized Data-Driven Energy Prediction Model with Uncertainty for a Milling Machine Tool using Gaussian Process

June 8, 2015
Author(s)
Jinkyoo Park, Raunak Bhinge, Nishant Biswas, Amrita Srinivasan, Kincho H. Law, David Dornfeld, Moneer Helu, Sudarsan Rachuri
Using a machine learning approach, this study investigates the effects of machining parameters on the energy consumption of a milling machine tool, which would allow selection of optimal operational strategies to machine a part with the minimum energy

Automated Guided Vehicle Bumper Test Method Development

June 2, 2015
Author(s)
Richard J. Norcross, Roger V. Bostelman, Joseph A. Falco
The National Institute of Standards and Technology (NIST) is developing test methods for contact bumpers used on Automated Guided Vehicles (AGVs) as basis for safety standards. This paper describes proposed test methods, force measurements for contact
