Chirp characterization of external modulators with finite extinction ratio using linear optical sampling
We demonstrate a network monitoring technique for the frequency chirping of external modulators based on linear optical sampling. We present α parameter waveforms of digital data modulation from simultaneously measured amplitude and phase. Digital data

TRECVID 2009 -- Goals, Tasks, Data, Evaluation Mechanisms and Metrics
The TREC Video Retrieval Evaluation (TRECVID) 2009 was a TREC-style video analysis and retrieval evaluation, the goal of which was to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. 63 teams from various
Secure Domain Name System (DNS) Deployment Guide
[Superseded by SP 800-81-2 (September 2013): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=914217 ] This document provides deployment guidelines for securing the Domain Name System (DNS) in any enterprise a government agency or a corporate
A Novel Ring-Based Performance Analysis for Call Admission Control in Wireless Networks
In Orthogonal Frequency Division Multiplex (OFDM) wireless networks such as 3GPP LTE and IEEE 802.16 WiMAX, the scheduler should allocate more resources to users with lower channel quality, such as users near the edge of the Base Station (BS) coverage area

RFSQUID-Mediated Coherent Tunable Coupling Between a Superconducting Phase Qubit and a Lumped Element Resonator
We demonstrate coherent tunable coupling between a superconducting phase qubit and a lumpedelement resonator. The coupling strength is mediated by a flux-biased rf SQUID operated in the nonhysteretic regime. By tuning the applied flux bias to the rf SQUID
Guide to Protecting Personally Identifiable Information
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-122, Guide to Protecting the Confidentiality of Personally Identifiable Information (PII). Written by Erika McCallister, Tim Grance, and Karen Scarfone of NIST, the

NIR Single photon detectors with up-conversion technology and its applications in quantum communication systems
Privacy-Preserving DRM
This paper describes and contrasts two families of schemes that enable a user to purchase digital content without revealing to anyone what item he has purchased. One of the basic schemes is based on anonymous cash, and the other on blind decryption. In
Privacy-Preserving DRM
How often and how long should a cognitive radio sense the spectrum?
This paper presents a Bayesian framework and a pricing structure for a secondary wireless user that opportunistically uses a RF channel belonging to a network of N primary users. The secondary user operates in a time-slotted fashion, where each time slot
Guide to Protecting the Confidentiality of Personally Identifiable Information (PII)
The purpose of this document is to assist Federal agencies in protecting the confidentiality of personally identifiable information (PII) in information systems. The document explains the importance of protecting the confidentiality of PII in the context

Detection and spectral measurement of single photons in communication bands using up-conversion technology
Quantum information systems are commonly operated in conventional communication bands (1310 and 1550 nm) over an optical fiber to take advantage of low transmission loss. However, the detection and spectral measurement of single photons in these
On Hash Functions Using Checksums
We analyse the security of iterated hash functions that compute an input dependent checksum which is processed as part of the hash computation. We show that a large class of such schemes, including those using non-linear or even one- way checksum functions
E-mail Security: an Overview of Threats and Safeguards
This publication discusses, at a high level, the ubiquitous threats facing email systems today and impresses the need to secure these systems. This article will provide high level tips and techniques for securing email systems and point to resources that
Confidence Regions for Parameters of Linear Models
A method is suggested for constructing a conservative confidence region for the parameters of a general linear model. In meta-analytical applications, when the results of independent but heterogeneous studies are to be combined, this region can be employed
