Algorithm Validation Using Multicolor Phantoms

May 9, 2012
Author(s)
Daniel V. Samarov, Matthew L. Clarke, Ji Y. Lee, David W. Allen, Maritoni A. Litorja, Jeeseong Hwang
We present a framework for hyperspectral image (HSI) analysis validation, specifically abundance fraction estimation based on HSI measurements of water soluble dye mixtures printed on microarray chips. In our work we focus on the performance of two

Designing Microarrays Phantoms for Hyperspectral Imaging Validation

May 9, 2012
Author(s)
Matthew L. Clarke, Ji Y. Lee, Daniel V. Samarov, David W. Allen, Maritoni A. Litorja, Ralph Nossal, Jeeseong Hwang
The simple design of custom-tailored microarrays for the characterization of hyperspectral imaging systems and analysis methods for biologically relevant samples. Individual and mixtures of dyes were printed on microscope slides and imaged by a

Structure and stability of hydrated ss-MnO2 surfaces

May 9, 2012
Author(s)
Gloria A. Oxford, Anne M. Chaka
Hydration of the β-MnO2 (110), (100), and (101) surfaces is investigated using a combination of periodic density functional theory and ab initio thermodynamics. Fully hydrated surfaces are found to be significantly more stable than the stoichiometric ones

Computer Security Division 2011 Annual Report

May 8, 2012
Author(s)
Patrick D. O'Reilly
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry

Probing the Water Content in Polymer Electrolyte Fuel Cells Using Neutron Radiography

May 8, 2012
Author(s)
Daniel S. Hussey, Jeffrey Mishler, Yun Wang, Rangachary Mukundan, Jacob Spendelow, Rodney Borup
This in-situ study examines the water content in polymer electrolyte fuel cells (PEFCs) using neutron radiography. Various conditions such as different polytetraflouroethylene (PTFE) loadings in the gas diffusion media including the micro-porous layer (MPL

TRECVID 2011 -- An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

May 8, 2012
Author(s)
Paul D. Over, George M. Awad, Jonathan G. Fiscus, Brian Antonishek, Martial Michel, Alan Smeaton, Wessel Kraaij, Georges Quenot
The TREC Video Retrieval Evaluation (TRECVID) 2011 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. Over the last ten

An Overview of Polymer Electrolyte Membranes for Fuel Cell Applications

May 7, 2012
Author(s)
Brandon W. Rowe, Kirt A. Page
While fuel cells have receive considerable attention over the last 10-20 years, the history of hydrogen fuel cells dates back to 1838. It would take more than a century before polymers would be impletmented as an electrolyte for proton transport (1955) and
