Analyzing a Co-Polymer Aramid Fiber for Use in Soft Body Armor

October 25, 2013
Author(s)
Walter G. McDonough, Jae Hyun Kim, Nathanael A. Heckert, Amanda L. Forster, Scott A. Wight, Joy P. Dunkers, Gale A. Holmes
Since the well-publicized failure of body armor used by a police officer, it has become imperative that the long-term properties and performance of new fibers being considered for use be understood. The range of interest is from the molecular properties of

Connection between thermodynamics and dynamics of simple fluids in highly attractive pores

October 25, 2013
Author(s)
William P. Krekelberg, Vincent K. Shen, Daniel W. Siderius, Thomas M. Truskett, Jeffrey R. Errington
We investigate the structural and diffusive dynamics properties of a model fluid in highly-absorptive cylindrical pores. At subcritical temperatures, self diffusion displays three distinct regimes as a function of average pore density ρ: 1) a decrease in

Bryan M. Barnes, Martin Y. Sohn, Francois R. Goasmat, Hui Zhou, Andras Vladar, Richard M. Silver, Abraham Arceo
Identifying defects in photolithographic patterning is a persistent challenge in semiconductor manufacturing. Well-established optical methods in current use are jeopardized by upcoming sub-20 nm device dimensions. Volumetric processing of focus-resolved

Towards Mobile Manipulator Safety Standards

October 24, 2013
Author(s)
Jeremy A. Marvel, Roger V. Bostelman
We present an overview of the current safety standards for industrial robots and automated guided vehicles (AGVs), and describe how they relate to the safety concerns of mobile manipulators (robot arms mounted on mobile bases) in modern manufacturing

A Literature Review of Sensor Ontologies for Manufacturing Applications

October 23, 2013
Author(s)
Craig I. Schlenoff, Tsai Hong Hong, Roger D. Eastman
The purpose of this paper is to review existing sensor and sensor network ontologies to understand whether they can be reused as a basis for a manufacturing perception sensor ontology, or if the existing ontologies hold lessons for the development of a new

A versatile bilayer resist for laser lithography at 405 nm on glass substrates

October 23, 2013
Author(s)
Quandou (. Wang, Ulf Griesmann
We describe a simple bilayer photoresist that is particularly well suited for laser lithography at an exposure wavelength of 405 nm on glass substrates, which is often used for the fabrication of binary diffractive optics and computer generated holograms

Exploiting dimensionality and defect mitigation to create tunable microwave dielectrics

October 23, 2013
Author(s)
Nathan D. Orloff, C H. Lee, T Birol, J A. Mundy, V. Goian, R. Haislmaier, E. Vlahos, Y. Kim, J. D. Brock, Y Zhu, R. Uecker, V. Gopalan, S. Kamba, X X. Xi, D A. Muller, I. Takeuchi, James C. Booth, C. J. Fennie
The miniaturization and integration of frequency-agile microwave circuits—tunable filters, resonators, phase shifters and more—with microelectronics offers tantalizing device possibilities, yet requires thin films whose dielectric constant at GHz
