The Current State and Recent Trends of the U.S. Manufacturing Industry

December 20, 2012
Author(s)
Douglas Thomas
This report brings together multiple sources of aggregate manufacturing industry data and industry subsector data to develop a quantitative depiction of the U.S. manufacturing industry. It compares the U.S. manufacturing industry to its international

Microelectromechanical systems based Stewart platform with sub-nano resolution

December 3, 2012
Author(s)
Seung Ho Yang, Yong Sik Kim, Jae M. Yoo, Nicholas G. Dagalakis
Currently difficulties exist in the fabrication of microelectromechanical systems (MEMS) in the form of Stewart platforms. The macroscale positioning technology, such as universal joints, ball and roller bearings and commercial actuators, used for building

A Humidity Generator for Temperatures to 200 degC and Pressures to 1.6 MPa

November 30, 2012
Author(s)
D Vega-Maza, W. Wyatt Miller, Dean C. Ripple, Gregory E. Scace
We have constructed a new humidity generator that produces gas streams of known moisture content at temperatures from 85 °C to 200 °C, absolute pressures from 0.2 MPa to 1.6 MPa, and relative humidities from 10 % to 90 %. The generator produces a moist gas

Formation of Extended Ionomeric Network by Bulk Polymerization of L,D-lactide with Layered Double Hydroxide

November 22, 2012
Author(s)
Edward D. McCarthy, Mauro Zammarano, Douglas M. Fox, Ryan Nieuwendaal, Yeon S. Kim, P H. Maupin, Paul C. Trulove, Jeffrey W. Gilman
We report the formation of an ionomeric network in a poly(L,D-lactide) hybrid nanocomposite, (PLDLA-HYB) during in-situ melt polymerization of L,D lactide in the presence of magnesium/aluminium layered-double-hydroxide (LDH) without added catalyst. The

A Sensor Model for Enhancement of Manufacturing Equipment Data Interoperability

November 15, 2012
Author(s)
Kang B. Lee, Yuyin Song, Peter S. Gu
Sensors can provide real-time production information to optimize manufacturing activities in a factory. Recently, more attention has been paid to the application of sensors in smart manufacturing systems. Sensor data exchange, sharing, and interoperability

The 2012 IEEE Robotics and Automation Society Safety, Security and Rescue Robotics Summer School was held from the 9th to the 15th of September in Alanya, Turkey, and brought together a select group of students, researchers, responders, manufacturers and

SysML extension for dynamical system simulation tools

October 26, 2012
Author(s)
Ion Matei, Conrad E. Bock
Computer-interpretable representations of system structure and behavior are at the center of designing today’s complex systems. Engineers create and review such representations using graphical modeling languages that support specification, analysis, design

Thermal Issues in Machine Tools
