Modeling queuing dynamics of TCP: a simple model and its empirical validation.

May 6, 2011
Author(s)
Daniel I. Genin, Anastase Nakassis
Understanding queuing dynamics of TCP is important for correct router buffer sizing as well as for optimizing the performance of the TCP protocol itself. However, modeling of buffer content dynamics under TCP has received relatively little attention given

Filtering noise with a quantum probe

May 5, 2011
Author(s)
John J. Bollinger
I discuss in general terms the ideas behind the manuscript "Single-ion quantum lock-in amplifier" by Kotler and colleagues which is scheduled to be published in the journal Nature. The Kotler manuscript describes a generalization of the concept of lock-in

From the Editor's Desk: Communication is Vital

May 5, 2011
Author(s)
Catherine A. Remley
This is an Editorial for the June, 2011 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).

Tumor Volume Measurement Errors of RECIST Studied With Ellipsoids

May 5, 2011
Author(s)
Zachary H. Levine, Benjamin R. Galloway, Adele P. Peskin, C. P. Heussel, Joseph J. Chen
RECIST (Response Evaluation Criteria in Solid Tumors) is a linear measure intended to predict tumor volume in medical computed tomography (CT). In this work, using purely geometrical considerations, we establish limits for how well RECIST can predict the

Assessing the shelf-life of a prototype reference material for product emissions testing

May 2, 2011
Author(s)
Cynthia H. Reed, Daniel V. Samarov, Dennis D. Leber, Zhe Liu, John Little
The National Institute of Standards and Technology (NIST) and Virginia Tech (VT) are developing a volatile organic compound (VOC) reference material to validate product emissions chamber testing. To verify the storage method of the material and determine

Combinatorial Screening of Hydrogel Scaffolds for 3D Cell Culture

May 2, 2011
Author(s)
Kaushik Chatterjee, Marian F. Young, Carl Simon Jr.
Optimizing cell-material interactions is critical towards maximizing regeneration in tissue engineering. Combinatorial and high-throughput (CHT) methods can be used to systematically screen tissue scaffolds to identify optimal biomaterial properties

Comparison of Diesel Fuel Oxygenates with Composition-Explicit Distillation Curve Method Part 1: Linear Compounds with One to Three Oxygens

May 2, 2011
Author(s)
Thomas J. Bruno, Tara Lovestead, Jennifer Riggs, Erica Jorgensen, Marcia L. Huber
There is a great deal of interest in formulating oxygenated diesel fuels that produce low particulate emissions. The most common oxygenating additives for diesel fuels include the glycol ethers, glycol esters, alcohols, ethers and ketones. It is important

Encryption Basics

May 2, 2011
Author(s)
Kevin M. Stine, Quynh H. Dang
Healthcare and health information technology professionals are entrusted with patient data which, because of its personal nature, requires protection to ensure its confidentiality. To provide this protection, these professionals frequently look to commonly

Grain Moisture Meter Test Methods and Tolerances

May 2, 2011
Author(s)
Gloria D. Lee
Due to the significant economic impact of each grain moisture meter and the importance of applying correct test methods and tolerances, this article has been written to answer recent inquires regarding using the two test methods in NIST Handbook 44

Inter-laboratory study approach to validate the performance of a prototype reference material for product emissions testing

May 2, 2011
Author(s)
Cynthia H. Reed, Andrew K. Persily, Zhe Liu, Steve Cox, John Little, Wolfgang Horn, Olaf Wilke, Katharina Wiegner
Product emissions chamber testing involves a complex protocol with several sources of measurement uncertainty (ASTM, 2010; ISO, 2006). Despite the potential for significant variability in measurement results within and among laboratories, there is no

Low Vibration Sensitivity Fiber Spools for Laser Stabilization

May 2, 2011
Author(s)
Archita Hati, T Li, B. Argence, A. Haboucha, H. Jiang, J. L. Dornaus, D Kone, A. Clairon, P. Lemonde, G. Santarelli, Craig W. Nelson, E. Burt
Mechanical vibration induced frequency noise is dominated at low Fourier frequencies in a fiber spool stabilized laser. Environmental vibration causes mechanical deformations in the fiber which induce phase fluctuations and then convert into excess

Neutron Charged Radius and the Neutron Electric Form Factor

May 2, 2011
Author(s)
Thomas R. Gentile, C.B. Crawford
For nearly forty years, the Galster parametrization has successfully fit existing data for the neutron electric form factor, GEn,vs. the square of the four-momentum transfer, Q^2. Typically this parametrization is constrained to be consistent with

On The Magnitude of Random Telegraph Noise in Ultra-Scaled MOSFETs

May 2, 2011
Author(s)
Kin P. Cheung, Jason P. Campbell
Random telegraph noise (RTN) has been shown to be a more severe scaling issue than the Random Dopant Effect (RDE). However this observation relies heavily on studies which focus only on threshold voltage (VTH) fluctuations. VTH measurements make separation

Relationship between Persistent Organic Pollutants (POPs) and Ranging Patterns in Common Bottlenose Dolphins (Tursiops truncatus) from Coastal Georgia, USA

May 2, 2011
Author(s)
John Kucklick, Brian C. Balmer, Lori Schwacke, Randall Wells, Clay George, Jennifer Hoguet, Suzanne Lane, Anthony Martinez, William McLellan, Patricia Rosel, T K. Rowles, Kate Sparks, Todd Speakman, Eric Zolman, D A. Pabst
Bottlenose dolphins (Tursiops truncatus) are apex predators and common in coastal southeastern U.S. waters; as such they are indicators of persistent organic pollutants (POPs) in coastal ecosystems. The concentrations of POPs and patterns of specific

SUSTAINABLE MANUFACTURING INDICATOR REPOSITORY

May 2, 2011
Author(s)
Shaw C. Feng, Prabir Sarkar, Che B. Joung, John Carrell
Sustainable manufacturing promotes manufacturing processes that minimize environmental and social impacts while maintaining economic benefits. To achieve this, manufacturers seek metrics and measurement methods to enable them to track the progress and
