Information Security in the System Development Life Cycle

September 1, 2004
Author(s)
Annabelle Lee, Tanya L. Brewer
Many system development life cycle (SDLC) models exist that can be used by an organization to effectively develop an information system. Security should be incorporated into all phases, from initiation to disposition, of an SDLC model. This Bulletin lays

Infrared Absorptions of the H 2 0 H 2 Complex Trapped in Solid Neon

September 1, 2004
Author(s)
D Forney, Marilyn E. Jacox, Warren E. Thompson
When a sample of neon to which have been added less than 1% each of H 2 and H 2O is deposited at 4.3 K, the infrared spectrum of the resulting solid includes an absorption by the vibrational fundamental of H 2, which is normally infrared-inactive. New

Infrared frequency comb for frequency metrology based on a tunable repetition rate fiber laser

September 1, 2004
Author(s)
Brian Washburn, Scott Diddams, Nathan R. Newbury, Jeffrey W. Nicholson, Feder Kenneth, Paul S. Westbrook, C. G. Jorgensen
A phase-locked, all-fiber supercontinuum source based on an ultrashort fiber ring laser with a tunable repetition frequency is presented. The supercontinuum output comprises a frequency comb with a spacing set by the laser repetition rate and an offset set

Materials reliability Division FY 2004 Programs and Accomplishments

September 1, 2004
Author(s)
Alan F. Clark
The Materials Reliability Division mission is to develop and disseminate measurement methods and standards enhancing the quality and reliability of materials for industry. We have changed our portfolio of research projects slightly this past year, as we

NIST Special Database #28

September 1, 2004
Author(s)
Reference Data Set V. National software reference library
The goal of this document is to help W3C editors write better specifications, by making a specification easier to interpret without ambiguity and clearer as to what is required in order to conform. It focuses on how to define and specify conformance. It

NIST's Logistics Integration Solutions

September 1, 2004
Author(s)
Sharon J. Kemmerer
The NIST Manufacturing Interoperability Program staff has years of experience developing standards, validating solutions, and providing interoperability results in the field of manufacturing. Building on this experience, NIST can: (1) Work with industry to

On the Feasibility of Single Molecule Detection of the Guanosine-Analogue, 3-MI

September 1, 2004
Author(s)
J E. Sanabia, Lori S. Goldner, P A. Lacaze, M E. Hawkins
We present UV fluorescence fluctuation correlation spectroscopy (FCS) measurements on the guanosine-analog 3-MI [3-Methyl-8-(2-deoxy- -D-ribofuranosyl)isoxanthopterin], a pteridine widely used in studies of DNA binding and dynamics. We measure the photon

Oxidative DNA Damage: Induction, Repair and Significance

September 1, 2004
Author(s)
M D. Evans, Miral M. Dizdar, M S. Cooke
The generation of reactive oxygen species may be both beneficial to cells, performing a function in inter- and intra-cellular signaling, and detrimental, modifying cellular bimolecules, accumulation of which has been associated with numerous diseases. Of

Precision Feshbach Spectroscopy of Ultracold Cs-2

September 1, 2004
Author(s)
C Chin, Vladan Vuletic, A J. Kerman, S G. Chu, Eite Tiesinga, P J. Leo, Carl J. Williams
We have observed > 60 magnetic field-induced Feshbach resonances in ultra-cold collisions of ground-state cesium atoms. The resonances have been detected using three different scattering processes: elastic collisions, inelastic collisions and radiative

Rate Adaptive Video Transmission Over Ad-Hoc Networks

September 1, 2004
Author(s)
Hamid Gharavi, K Ban
In mobile ad-hoc network environments where the network topology is expected to change considerably, providing reliable video communications is a challenging task. This paper is mainly concerned with developing a packet control mechanism to reduce bursts
