DNS Security Introduction and Requirements, RFC 4033

March 1, 2005
Author(s)
R Arends, R Austein, M Larson, Daniel Massey, Scott W. Rose
The Domain Name System Security Extensions (DNSSEC) add data origin authentication and data integrity to the Domain Name System. This document introduces these extensions and describes their capabilities and limitations. This document also discusses the

Down Selection Process, IEEE 802.21-05-215-04

March 1, 2005
Author(s)
Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Effect of Positive Pressure Ventilation on a Room Fire

March 1, 2005
Author(s)
Stephen Kerber, William D. Walton
Fire departments use ventilation blowers or fans to pressurize a structure prior to suppressing a fire. This pressurization or positive pressure ventilation (PPV) tactic has not been characterized carefully enough to establish specific guidelines for

Electric Current Induced Thermomechanical Fatigue Testing of Interconnects

March 1, 2005
Author(s)
Robert Keller, Roy H. Geiss, Yi-Wen Cheng, David T. Read
We demonstrate the use of electrical methods for evaluating the thermomechanical fatigue properties of patterned aluminum and copper interconnects on silicon-based substrates. Through a careful selection of alternating current frequency and current density

Evolution of Deformation Induced Surface Morphologies Generated in Fe-based Sheet

March 1, 2005
Author(s)
Mark R. Stoudt, Joseph B. Hubbard, Stephen W. Banovic
The complex strain states that exist within a real metal stamping are likely to generate different surface morphologies when compared to the same level of plastic strain produced via single pass deformation. This study quantifies the surface morphology

Ferryl (Fe=O) Termination of the Hematite a-Fe2O3(0001) Surface

March 1, 2005
Author(s)
C Lemire, S Bertarione, A Zechina, D Scarano, Anne M. Chaka, H J. Freund
Using scanning tunnelling microscopy and infrared reflection absorption spectroscopy we have observed that the alpha-Fe2O3(0001) surface unexpectedly exhibits ferryl (Fe=O) groups, which may coexist with domains of the Fe-terminated surface. The ab initio

Final Down Selection Process, IEEE 802.21-05-262-04

March 1, 2005
Author(s)
Nada T. Golmie
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Flame Extinguishment in a Cup-Burner Apparatus

March 1, 2005
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
Unsteady extinguishment phenomena of laminar methane-air co-flow diffusion flames formed in a cup-burner apparatus at normal earth gravity have been studied experimentally and computationally. A gaseous fire-extinguishing agent (CO 2, N 2, He, Ar, or CF 3H

Guide for the Selection of Chemical Agent and Toxic Industrial Material Detection Equipment for Emergency First Responders, Guide 100-04 Vol. I & II

March 1, 2005
Author(s)
Alim A. Fatah, Richard D. Arcilesi, James C. Peterson, Charlotte H. Lattin, Corrie Y. Wells
The purpose of the Guide for the Selection of Explosives Detection and Blast Mitigation Equipment for Emergency First Responders is to provide responder groups with information to aid them in the selection and purchase of explosives detection and blast

Information Models for Product Representation: Core and Assembly Models

March 1, 2005
Author(s)
Sudarsan Rachuri, Mehmet M. Baysal, Utpal Roy, Sebti Foufou, Conrad Bock, Steven J. Fenves, Eswaran Subrahmanian, Kevin W. Lyons, Ram D. Sriram
This paper presents a revised and unified view of the NIST Core Product Model (CPM) [1; 2] and the NIST Open Assembly Model (OAM) [3]. The CPM provides a base-level product model that is not tied to any vendor software; open; non-proprietary; simple

Interfacial Structure of Photoresist Thin Films in Developer Solutions

March 1, 2005
Author(s)
Vivek M. Prabhu, B D. Vogt, Wen-Li Wu, Jack F. Douglas, Sushil K. Satija, D M. Goldfarb, H Ito
The development step is critical to the fabrication of nanostructures in chemically amplified photoresist technology. With critical dimensions (CD) shrinking to sub-100 nm and the concurrent reduction in exposure radiation wavelength, line-edge roughness

Interference Testing, IEEE 802.19-05-36-02

March 1, 2005
Author(s)
David E. Cypher
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the bit-stream, generation of random numbers and processing of the sifting algorithm are all handled

Interstellar Chemistry: A Strategy for Detecting Polycyclic Aromatic Hydrocarbons in Space

March 1, 2005
Author(s)
Francis J. Lovas, R J. McMahon, J-U Grabow, M Schnell, J Mack, L T. Scott, R L. Kuczkowski
Polycyclic aromatic hydrocarbons (PAHs) represent important targets for radio astronomy because they offer the possibilities of validating the PAH hypothesis and revealing new insight into the chemistry of interstellar space. Polycyclic aromatic

Measurement of Second Order Susceptibilities of GaN and AlGaN

March 1, 2005
Author(s)
Norman Sanford, Albert Davydov, Denis V. Tsvetkov, Vladimir A. Dmitriev, Stacia Keller, Umesh Mishra, Steven P. DenBaars, S S. Park, J H. Han
Rotational Maker fringes, scaled with respect to χ 11 (2) of crystalline quartz, were used to determine the nonlinear optical coefficients χ 31 (2) and χ 33 (2) for samples of thin Al xGa 1-xN films and a bulk free-standing GaN platelet. The Al xGa 1-xN

Measurement of Weak Signals Using a Communications Receiver System

March 1, 2005
Author(s)
Marc Rutschlin, Kate Remley, Robert T. Johnk, Dylan Williams, Galen H. Koepke
We describe the calibration of an inexpensive, reliable system for use in weak-signal detection. The calibration procedure described allows the conversion of signals measured with the communications receiver system-which is based on a standard
