NIST Big Data Interoperability Framework: Volume 4, Security and Privacy

October 21, 2019
Author(s)
Wo L. Chang, Arnab Roy, Mark Underwood
Big Data is a term used to describe the large amount of data in the networked, digitized, sensor-laden, information-driven world. While opportunities exist with Big Data, the data can overwhelm traditional technical approaches and the growth of data is

NIST Big Data Interoperability Framework: Volume 6, Reference Architecture

October 21, 2019
Author(s)
Wo L. Chang, David Boyd, Orit Levin
Big Data is a term used to describe the large amount of data in the networked, digitized, sensor-laden, information-driven world. While opportunities exist with Big Data, the data can overwhelm traditional technical approaches, and the growth of data is

NIST Big Data Interoperability Framework: Volume 7, Standards Roadmap

October 21, 2019
Author(s)
Wo L. Chang, Russell Reinsch, David Boyd, Carl Buffington
While opportunities exist with Big Data, the data can overwhelm traditional technical approaches. To advance progress in Big Data, the NIST Big Data Public Working Group (NBD-PWG) is working to develop consensus on important, fundamental concepts related

NIST Big Data Interoperability Framework: Volume 9, Adoption and Modernization

October 21, 2019
Author(s)
Wo L. Chang, Russell Reinsch, Claire C. Austin
The potential for organizations to capture value from Big Data improves every day as the pace of the Big Data revolution continues to increase, but the level of value captured by companies deploying Big Data initiatives has not been equivalent across all

Security Automation for Cloud-Based IoT Platforms

October 21, 2019
Author(s)
Robert B. Bohn, Mheni Merzouki, Charif Mahmoudi, Cihan Tunc
Internet of Things (IoT) is reshaping the way Cloud Service Providers (CSP) collect data from sensors. With billions of devices deployed around the world, CSP are providing platforms dedicated to IoT that provides advanced features for those devices. This

Spin Rotation Induced by Applied Pressure in Cd-Doped Ce 2 RhIn 8 Intermetallic Compound

October 21, 2019
Author(s)
D. S. Christovam, C. Giles, L. Mendonca-Ferreira, Juscelino Leao, William D. Ratcliff, Jeffrey W. Lynn, S. Ramos, E. N. Hering, H. Hidaka, E. Baggio-Saitovich, Z. Fisk, P. G. Pagliuso, C. Adriano
The pressure evolution of the magnetic properties of the Ce 2RhIn 7.79Cd 0.21 heavy fermion compound was investigated by single crystal neutron magnetic diffraction and electrical resistivity experiments under applied pressure. From the neutron magnetic

Tunable Magnetic Ordering through Cation Selection in Entropic Spinel Oxides

October 21, 2019
Author(s)
Brianna Musico, Quinton Wright, T. Zac Ward, Alexander Grutter, Elke Arenholz, Dustin Gilbert, David Mandrus, Veerle Keppens
Twelve multicomponent spinels, comprised of (Mg, Cr, Mn, Co, Fe, Ni, Cu, and/or Zn)(Cr, Fe or Al) 2O 4, were prepared using solid state synthesis methods, resulting in nine homogenous, single phase samples with a Fm-3m structure, and three samples with

Characterization and Computation of Matrices of Maximal Trace over Rotations

October 19, 2019
Author(s)
Javier Bernal, James F. Lawrence
The constrained orthogonal Procrustes problem is the least-squares problem that calls for a rotation matrix that optimally aligns two corresponding sets of points in d-dimensional Euclidean space. This problem generalizes to the so-called Wahba's problem

Using Structural Phase Transitions to Enhance the Coercivity of Ferromagnetic Films

October 17, 2019
Author(s)
Ryan F Need, Josh Lauzier, Logan Sutton, Brian J Kirby, Jose de la Venta
Storing information in magnetic recording technologies requires careful optimization of the recording media's magnetic properties. For example, heat-assisted magnetic recording (HAMR) relies on a pre-recording heating step that momentarily lowers the

Validating Predictive Models with Outdoor Data

October 17, 2019
Author(s)
Christopher C. White, Donald L. Hunston, Li Piin Sung, Hsiang C. Hsueh, Adam L. Pintar, Deborah S. Jacobs
The NIST service life prediction program has demonstrated success in producing validated predictions for the property change resulting from outdoor exposure for a range of polymer systems including Epoxy, Polyethylene, Polyester, Polyethylene terephthalate

Mission Critical Voice Quality of Experience Access Time Measurement Methods

October 15, 2019
Author(s)
Jaden K. Pieper, Jesse M. Frey, Chelsea J. Greene, Zainab O. Soetan, Silas T. Thompson, Donald A. Bradshaw, Steven Voran
Access time generally describes the time associated with the establishment of a talk path upon user request to speak and has been identified as a key component of Quality of Experience (QoE) in communications. NIST’s Public Safety Communications Research

Orientational Distribution Function of Aligned Elongated Molecules and Particulates Determined from Their Scattering Signature

October 15, 2019
Author(s)
Guan-Rong Huang, Yangyang Wang, Changwoo Do, Yuya Shinohara, Takeshi Egami, Lionel Porcar, Yun Liu, Wei-Ren Chen
We present a strategy for quantitatively evaluating the field-induced alignment of non-spherical particles using small angle scattering techniques. The orientational distribution function (ODF) is determined from the anisotropic scattering intensity via

Biomimetic Approach to Inhibition of Photooxidation in Organic Solar Cells Using Beta-Carotene as an Additive

October 14, 2019
Author(s)
Sebastian Engmann, Vida Turkovic, Michela Prete, Mikkel Bregnhoj, Liana Inasaridze, Dmytro Volyniuk, Filipp Obrezkov, Juozas V. Grazulevicius, Horst G. Rubahn, Pavel Troshin, Peter R. Ogilby, M. Madsen
Recent improvements in the power conversion efficiencies of organic photovoltaic (OPV) cells have highlighted the fact that OPV device lifetimes are now the main bottleneck for further advances of this technology. As such, understanding and controlling
