On February 12, 2014 President Obama issued a statement that, "[c]yber threats pose one the gravest national security dangers that the United States faces. To better defend our nation against this systemic challenge, one year ago I signed an Executive

Overview of the TREC-2012 Microblog Track

June 2, 2014
Author(s)
Ian M. Soboroff, Iadh Ounis, Jimmy Lin, Craig Macdonald
The Microblog track examines search tasks and evaluation meth- odologies for information seeking behaviours in microblogging en- vironments such as Twitter. It was first introduced in 2011, address- ing a real-time adhoc search task, whereby the user

Polar codes in a QKD Environment

May 22, 2014
Author(s)
Anastase Nakassis, Alan Mink
Polar coding is the most recent encoding scheme in the quest for error correction codes that approaches the Shannon limit, has a simple structure, and admits fast decoders. As such, it is an interesting candidate for the quantum key distribution (QKD)

The Case for Delivering the Infrastructure for Digital Building Regulations

May 19, 2014
Author(s)
Mark E. Palmer, James H. Garrett
The building industry uses numerous engineering standards, building codes, specifications and regulations and a diverse set of industry vocabularies to describe, assess, and deliver constructed facilities. As part of the expanding use of building

LTE Physical Layer Performance Analysis

May 15, 2014
Author(s)
Wen-Bin Yang, Michael R. Souryal
In this report, we present results of a physical layer performance study for all MCSs (from MCS0 to MCS28) in terms of block error rate (BLER) and spectral efficiency. The results are obtained by using the Steepest Ascent LTE toolbox for MATLAB which

TRECVID 2013 -- An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

May 5, 2014

Paul D. Over, Jonathan G. Fiscus, Gregory A. Sanders, David M. Joy, Martial Michel, George M. Awad, Alan Smeaton, Wessel Kraaij, Georges Quenot
TRECVID 2013 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. Over the last ten years this effort has yielded a better

Performance Testing and Evaluation of Transformative Apps Devices

April 16, 2014
Author(s)
Anthony J. Downs, Lisa J. Fronczek, Emile L. Morse, Brian A. Weiss, Ian P. Bashor, Craig I. Schlenoff
Transformative Apps (TransApps) is a Defense Advanced Research Projects Agency (DARPA) funded program whose goal is to develop a range of militarily-relevant software applications ("apps") to enhance the operational effectiveness of military personnel on

NIST and Computer Security

Author(s)
William E. Burr, Hildegard Ferraiolo, David A. Waltermire
The US National Institute of Standards and Technology's highly visible work in four key areas--cryptographic standards, role-based access control, identification card standards, and security automation--has and continues to shape computer and information

Optical volumetric inspection of sub-20 nm patterned defects with wafer noise

April 2, 2014
Author(s)
Bryan M. Barnes, Francois R. Goasmat, Martin Y. Sohn, Hui Zhou, Richard M. Silver, Andras Vladar, Abraham Arceo
We have previously introduced a new data analysis method that more thoroughly utilizes scattered optical intensity data collected during defect inspection using bright-field microscopy. This volumetric approach allows conversion of focus resolved 2-D

An Empirical Comparison of Combinatorial and Random Testing

April 1, 2014
Author(s)
Laleh Ghandehari, Jacek Czerwonka, Yu Lei, Soheil Shafiee, Raghu N. Kacker, D. Richard Kuhn
Some conflicting results have been reported on the comparison between t-way combinatorial testing and random testing. In this paper, we report a new study that applies t-way and random testing to the Siemens suite. In particular, we investigate the

Calibrating multiple microscopes with a smartphone

April 1, 2014
Author(s)
Peter Bajcsy, Mary C. Brady, Jacob Siegel
Summary: The iPhone liquid crystal displays allows efficient and accurate calibration of an inexpensive array of handheld microscopes for measuring microscopic dynamic events over a large field of view. How does one build an inexpensive array of handheld

Estimating Fault Detection Effectiveness

April 1, 2014
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
[Poster] A t-way covering array can detect t-way faults, however they generally include other combinations beyond t-way as well. For example, a particular test set of all 5-way combinations is shown capable of detecting all seeded faults in a test program

Human Engineering Design Criteria Standards Part 3: Interim Steps

April 1, 2014
Author(s)
Susanne M. Furman, Mary Theofanos, Hannah Wald
The Department of Homeland Security (DHS) requires general human systems integration (HSI) criteria for the design and development of human-machine interfaces for the technology, systems, equipment, and facilities employed by its user population. HSI is

An Interoperability Test Bed for Distributed Healthcare Applications

March 24, 2014
Author(s)
Robert D. Snelick
Standards provide the foundation for ensuring interoperability, but if they are not implemented correctly or consistently, their value is diminished leading to problematic installations and higher costs. Conformance and Interoperability testing is

An Integrated Detection System Against False Data Injection Attacks in the Smart Grid

March 4, 2014
Author(s)
Wei Yu, David W. Griffith, Linqiang Ge, Sulabh Bhattarai, Nada T. Golmie
The smart grid is a new type of power grid that will use the advanced communication network technologies to support more efficient energy transmission and distribution. The grid infrastructure was designed for reliability; but security, especially against
