Microwave generation in magnetic multilayers and nanostructures

September 1, 2007
Author(s)
William Rippard, Matthew Pufall
We present an overview of the coherent magnetic precessional dynamics induced by the spin transfer effect in magnetic nanostructures. The precessional frequencies of the magnetic oscillators can be tuned over a range of several gigahertz by varying the dc

Nanosecond Delay With Subpicosecond Uncertainty

September 1, 2007
Author(s)
Donald R. Larson, Nicholas Paulter
We have combined a commercially available, variable length coaxial delay line (trombone line) with a high resolution linear translation system. The result is better resolution and lower uncertainty in the achievable delays than previously available. The

NIST Workshop on Materials Test Procedures for Hydrogen Pipelines

September 1, 2007
Author(s)
Thomas A. Siewert, Joseph D. McColskey, Richard E. Ricker
The Materials Reliability and Metallurgy Divisions have expanded their efforts to advance the technology for the construction, repair, and inspection of pipelines. One key factor is to identify and prioritize the research needs of the pipeline community

Numerical Micromagnetics: Finite Difference Methods

September 1, 2007
Author(s)
J. Miltat, Michael J. Donahue
Micromagnetics is based on the one hand on a continuum approximation of exchange interactions, including boundary conditions, on the other hand on Maxwell equations in the non-propagative (static) limit for the evaluation of the demagnetizing field. The

SAMATE and Evaluating Static Analysis Tools

September 1, 2007
Author(s)
Paul E. Black
We give some background on the Software Assurance Metrics And Tool Evaluation (SAMATE) project and our decision to work on static source code security analyzers. We give our experience bringing government, vendors, and users together to develop a

Science based Information Metrology for Engineering Informatics

September 1, 2007
Author(s)
Sudarsan Rachuri
Engineering informatics is the discipline of creating, codifying (structure and behavior that is syntax and semantics), exchanging (interactions and sharing), processing (decision making), storing and retrieving (archive and access) the digital objects
