The NIST Cloud Federation Reference Architecture

February 13, 2020
Robert B. Bohn, Craig A. Lee, Martial Michel
This document presents the NIST Federated Cloud Reference Architecture model. This actor/role- based model used the guiding principles of the NIST Cloud Computing Reference Architecture to develop an eleven component model. This document describes these

Cloud Computing Service Metrics Description

April 24, 2018
Frederic J. de Vaulx, Eric D. Simmon, Robert B. Bohn
With cloud computing in the mainstream, there is a preponderance of cloud based services in the market and the choices for consumers increase daily. However, comparing the service offerings between cloud service providers is not a straightforward exercise

Cloud Security Automation Framework

October 12, 2017
Cihan Tunc, Salim hariri, Mheni Merzouki, Charif Mahmoudi, Frederic J. de Vaulx, Jaafar Chbili, Robert B. Bohn, Abdella Battou
Cloud services have gained tremendous attention as a utility paradigm and have been deployed extensively across a wide range of fields. However, Cloud security is not catching up to the fast adoption of its services and remains one of the biggest

NIST Cloud Computing Reference Architecture

September 8, 2011
Fang Liu, Jin Tong, Jian Mao, Robert B. Bohn, John V. Messina, Mark L. Badger, Dawn M. Leaf
The adoption of cloud computing into the Federal Government and its implementation depend upon a variety of technical and non-technical factors. A fundamental reference point, based on the NIST definition of Cloud Computing, is needed to describe an

Accelerating Scientific Discovery through Computation and Visualization

November 1, 2000
James S. Sims, John G. Hagedorn, Peter M. Ketcham, Steven G. Satterfield, Terence J. Griffin, William L. George, H A. Fowler, B A. am Ende, Howard Hung, Robert B. Bohn, John E. Koontz, Nicos Martys, Charles E. Bouldin, James A. Warren, D L. Feder, Charles W. Clark, Bernard J. Filla, Judith E. Terrill
The rate of scientific discovery can be accelerated through computation and visualization. This acceleration results from the synergy of expertise, computing tools, and hardware for enabling high performance computation, information science, and

Theory of Optical Absorption with Electron-Hole Attraction

November 1, 1998
Eric L. Shirley, L Benedict, Robert B. Bohn
This work presents calculations of the optical absorption spectra of semiconductors and insulators. The background and underlying physics are discussed, and the efficient computational method used is sketched. Results for eight solids are presented and
