RFID-based Localization and Tracking Technologies

April 1, 2011
Author(s)
Michael R. Souryal, Lionel M. Ni, Dian Zhang
Radio Frequency Identification (RFID) usually incorporates a tag into an object for the purpose of identification or localization using radio signals. It has gained a lot of attention recently due to its advantages in terms of low cost and easy deployment

Searching for applications with a fine-toothed comb

April 1, 2011
Author(s)
Nathan R. Newbury
Frequency combs, like many ground-breaking technologies, are simple in concept; they results from the spectrum of any regular train of optical pulses. What is remarkable is that this simple picture can be actually realized in a number of different

Wolter Optics for Neutron Focusing

April 1, 2011
Author(s)
David F. Mildner, M. V. Gubarev
Focusing optics based on Wolter optical geometries developed for x-ray grazing incidence beams can be designed for neutron beams. Wolter optics are formed by grazing incidence reflections from two concentric conic sections (for example, a paraboloid and a

Information Leakage Through the Domain Name System

March 31, 2011
Author(s)
Scott W. Rose, Anastase Nakassis, Ramaswamy Chandramouli
The Domain Name System (DNS) is the global lookup service for network resources. It is often the first step in an Internet transaction as well as a network attack. An attacker can query an organization's DNS as reconnaissance before attacking hosts on a

Introduction of a DC Bias into a High-Q Superconducting Microwave Cavity

March 31, 2011
Author(s)
Rimberg J. Alex, Fei Chen, Adam J. Sirois, Raymond Simmonds
We report a technique for applying a dc voltage or current bias to the center conductor of a high-quality factor superconducting microwave cavity without significantly disturbing selected cavity modes. This is accomplished by incorporating dc bias lines
