Derivation of Isosceles Trapezoidal Distribution

December 1, 2010
Author(s)
Raghu N. Kacker, James F. Lawrence
It is known that, if the mid-point of a rectangular distribution is specified, the half-width is inexactly known, and the state of knowledge about the half-width may be represented by a narrower rectangular distribution then the resulting distribution

December 1, 2010
Author(s)
Amaresh Chakrabarti, Sudarsan Rachuri, Prabir Sarkar, Srinivas Kota
This book is based on an anthology of papers from experts from the United States and India, along with a summary of focused discussions and suggestions in several areas of critical importance within the broad topic of sustainability in development of

From the Editor's Desk: A Little Friendly Competition

December 1, 2010
Author(s)
Catherine A. Remley
This is an Editorial for the December, 2010 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

MEASUREMENT OF WEIGHTED LED RADIANCE RELATED TO PHOTOBIOLOGICAL SAFETY

December 1, 2010
Author(s)
Tongsheng Mou, Yuqin Zong, Yoshi Ohno
Optical radiation safety of light-emitting diode (LED) products is being addressed in the International Electrotechnical Commission (IEC) standard document 62471-2006. Measurement of weighted radiance of LEDs, used to assess the maximal exposure related to

Modeling Smoldering Fires using the Computer Model CONTAM

December 1, 2010
Author(s)
William D. Davis
The computer model CONTAM was used to simulate the spread of smoke in a house with a working furnace during smoldering fires. Three smoldering experiments from a study on detector sensitivity and siting requirements conducted in 1975 using a two story

Neutron Imaging Studies of Metal-Hydride Storage Beds

December 1, 2010
Author(s)
David Jacobson, Daniel Hussey, Elias Baltic, Terrence J. Udovic, John J. Rush, Robert C. Bowman
Neutron radiography and tomography were used to study the transient and steady-state distributions, respectively, of hydrogen within a prototypical, LaNi4.78Sn0.22-based hydrogen storage bed during and after various absorption and desorption steps. It was

SANS from Pluronic P85 in d-water

December 1, 2010
Author(s)
Boualem Hammouda
Small-angle neutron scattering (SANS) has been used to investigate pluronic P85 (EO 26PO 40EO 26) copolymer in deuterated water. A range of P85 fractions were measured for a wide sample temperature window. A rich phase behavior is reported. Unimers were

The Effect of Substrate Material on Silver Nanoparticle Antimicrobial Efficacy

December 1, 2010
Author(s)
Benita Dair, Dave M. Saylor, T. E. Cargal, Grace R. French, Kristen M. Kennedy, Rachel S. Casas, Jonathan E. Guyer, James A. Warren, Steven K. Pollack
With the advent of Nanotechnology, silver nanoparticles increasingly are being used in coatings, especially in medical device applications, to capitalize on their antimicrobial properties. The increased antimicrobial efficacy of nanoparticulate silver

The Role of High-Field Stress in the Negative Bias Temperature Instability

December 1, 2010
Author(s)
Jason P. Campbell, Kin P. Cheung, John S. Suehle, A Oates
In this study, a fast drain current measurement methodology which supports the standard threshold voltage and transconductance extractions associated with the fast dynamic negative-bias temperature instability (NBTI) is presented. Using this methodology

US Anti-Counterfeiting Standards Development Activities: An Overview

December 1, 2010
Author(s)
Yaw S. Obeng, Eric D. Simmon, YaShian Li-Baboud
Counterfeit electronics components impact performance, hence can be viewed as a reliability concern. Several different strategies have been proposed to mitigate the penetration and impact of counterfeits on the supply chain. Standards afford effective

A review of fatigue crack growth for pipeline steels exposed to hydrogen

November 30, 2010
Author(s)
Nicholas Nanninga, Andrew J. Slifka, Yaakov Levy, Calvin L. White
Hydrogen pipeline systems offer an economical means of storing and transporting energy in the form of hydrogen gas. Pipelines can be used to transport hydrogen that has been generated at solar and wind farms to and from salt cavern storage locations. In

Broadband Measurements of Nanofiber Devices: Repeatability and Random Error Analysis

November 30, 2010
Author(s)
Thomas M. Wallis, Atif A. Imtiaz, SangHyun S. Lim, Pavel Kabos, Kichul Kim, Paul Rice, Dejan Filipovic
On-wafer, broadband measurements of two-port nanofiber devices were made in order to test the short-term repeatability of a widely used measurement approach that builds on established on-wafer calibration techniques. The test devices used in this study

Cryptanalysis of the ESSENCE Family of Hash Functions

November 30, 2010
Author(s)
Nicky Mouha , Gautham Sekar, Jean-Philippe Aumasson , Thomas Peyrin, Soren S. Thomsen , Meltem Sonmez Turan, Bart Preneel
ESSENCE is a family of cryptographic hash functions, accepted to the first round of NIST's SHA-3 competition. This paper presents the first known attacks on ESSENCE. We present a semi-free-start collision attack on 31 out of 32 rounds of ESSENCE-512

Electrospray Tandem Quadrupole Fragmentation of Quinolone Drugs and Related Ions. On the Reversibility of Water Loss from Protonated Molecules

November 30, 2010
Author(s)
Pedatsur Neta, Bhaskar Godugu, Yuxue Liang, Yamil Simon, Xiaoyu Yang, Stephen E. Stein
Selected reaction monitoring (SRM) of quinolone drugs showed1 different sensitivities in aqueous solution vs. biological extract. The authors suggested formation of two singly protonated ions with different behavior, one undergoing loss of H 2O and the
