Atom-Probe Tomographic Study of ?/?' Interfaces and Compositions in an Aged Co-Al-W Superalloy

December 12, 2012
Author(s)
Eric Lass, Kil-Won Moon, Maureen E. Williams, Carelyn E. Campbell, Ursula R. Kattner, David C. Dunand, Peter J. Bocchini, David N. Seidman
Atom-probe tomography (APT) is utilized to investigate, in a Co-9.7Al-10.8W at.% alloy aged at 900 °C for 1000 h, the phase composition and partitioning behavior of the two-phase ɣ(f.c.c.)/ɣ'(L12) microstructure. The APT composition of the ɣ-matrix (Co-8

RF and IF mixer optimum matching impedances extracted by large-signal vectorial measurements

October 7, 2003
Author(s)
Alessandro Cidronali, Giovanni Loglio, Jeffrey Jargon, Kate Remley, I. Magrini, Donald C. DeGroot, Dominique Schreurs, Kuldip Gupta, Gianfranco Manes
This paper introduces a new technique that allows us to measure the admittance conversion matrix of a two-port device, using a Nonlinear Vector Network Analyzer. This method is applied to extract the conversion matrix of a 0.2 micron pHEMT, driven by a 4.8

… economic burden from wildfire is estimated to be between $71.1 billion to $347.8 billion ($2016 US). Annualized costs are estimated to range from $7.6 billion to $62.8 billion. Annualized losses are estimated …

Long Polymerase Chain Reaction (PCR) for Variable Number of Tandem Repeats (VNTR) Analysis

November 1, 1999
Author(s)
Kristy L. Richie, M D. Goldsborough, M M. Darfler, E A. Benzinger, M L. Lovekamp, D J. Reeder, C D. O'Connell
The Polymerase Chain Reaction (PCR) has revolutionized the analysis of DNA from a variety of sources. With its sensitivity and ability to amplify degraded DNAs and small quantities of samples, coupled with fast turn-around-time, PCR is often the analytical

Operational Impacts of IEEE 802.1Qbv Scheduling on a Collaborative Robotic Scenario

October 17, 2022
Author(s)
Rick Candell, Karl Montgomery, Mohamed Hany, Susruth Sudhakaran, Justin Albrecht, Dave Cavalcanti
Time-sensitive networking (TSN) is an emerging topic for the advancement of wireless networking for industrial applications. TSN, as defined under the umbrella of IEEE 802.1 standards, addresses issues related to providing deterministic communications over

Detecting GNSS Spoofing using a Network of Hardware Oscillators

March 11, 2016
Author(s)
Dhananjay Anand, Tanvir M. Arafin, Gang Qu
In the face of growing concern about spoofing attacks on GNSS transmissions, we propose a scheme to cross validate GNSS based timing against intrinsic properties of local hardware oscillators. We demonstrate our approach as being able to detect certain

Highly Multiplexed Assays for Measuring Polymorphisms on the Y-Chromosome

October 17, 2003
Author(s)
John M. Butler, R Schoske, Peter Vallone
A multiplex PCR assay capable of amplifying 20 Y chromosome short tandem repeat (STR) markers simultaneously has been developed. These markers include all of the Y STRs that make up the extended haplotype used in Europe (DYS19, DYS385, DYS389I/II, DYS390
