Gathering relevant and credible information from massive, available data spaces is critical for intelligence analysis. We describe our ongoing effort in constructing a framework of services to...
Equation-free implementation of statistical moment closures (2007)
Alexander, Francis J., Johnson, Gregory, Eyink, Gregory L., Kevrekidis, Ioannis G.
We present a general numerical scheme for the practical implementation of statistical moment closures suitable for modeling complex, large-scale, nonlinear systems. Building on recently developed...
Statistical Mechanics of Histories: A Cluster Monte Carlo Algorithm (2005)
Gulbahce, Natali, Alexander, Francis J., Johnson, Gregory
We present an efficient computational approach to sample the histories of nonlinear stochastic processes. This framework builds upon recent work on casting a $d$-dimensional stochastic dynamical...

Clusters and Fluctuations at Mean-Field Critical Points and Spinodals (2000)
Klein, W., Gould, Harvey, Tobochnik, J., Alexander, F. J., Anghel, M., Johnson, Gregory
We show that the structure of the fluctuations close to spinodals and mean-field critical points is qualitatively different than the structure close to non-mean-field critical points. This difference...
Stable and Fault-Tolerant Object Allocation (2000)
Gregory Johnson, Ambuj K. Singh
Support for efficient dynamic migration and replication of objects is essential for achieving adequate performance and scalability. Traditional solutions to the problem focused on competitiveness....
An Architecture-Based Approach to Self-Adaptive Software (1999)
Peyman Oreizy Michael, Michael M. Gorlick, Richard N. Taylor, Dennis Heimbigner, Gregory Johnson, Nenad Medvidovic, ...
This article examines the fundamental role of software architecture in self-adaptive systems and outlines technologies we have considered for supporting the methodology.

Kearns, Edward J., Emmerson, Steven R., Olson, Donald B., Johnson, Gregory
The goal of the two cruises covered in this hydrographic data report was to survey the water masses and cross- and inter-basin transports at the height of the two monsoon regimes. The first cruise...
Hybrid Image Acquisition and Signal Processing Systems for High Resolution (1998)
Cathey, W. T., Johnson, Gregory, Tucker, Sara B., Wach, Hans B.
The primary goal of the research was to investigate longitudinal and lateral resolving power of hybrid optical/digital imaging systems. Most loss of resolution is due to aberrations in the lens. The...
Driscoll, Daniel, Patrick, Brian, Johnson, Gregory, Patton-Hall, Katherine, Turman, Gary M., Cornwell, Mike, ...
NSWCDD Has supported the JSLSCAD program through participation in joint IPTs for system development, logistics, and test and evaluation. As part of its role in support of Test and Evaluation NSWC...
Molecular Dynamics Study of Long-Lived Structures in a Fragile Glass Forming Liquid (1998)
Johnson, Gregory, Melcuk, Andrew I., Gould, Harvey, Klein, W., Mountain, Raymond D.
We present molecular dynamics results for a two component, two-dimensional Lennard-Jones supercooled liquid near the glass transition. We find that the supercooled liquid is spatially heterogeneous...
Monte Carlo study of the Widom-Rowlinson fluid using cluster methods (1997)
Johnson, Gregory, Gould, Harvey, Machta, J., Chayes, L. K.
The Widom-Rowlinson model of a fluid mixture is studied using a new cluster algorithm that is a generalization of the invaded cluster algorithm previously applied to Potts models. Our estimate of the...
The Harlem renaissance and its influence on the work of Gregory Johnson /--Gregory Johnson. (1991)
Includes exhibition program ([4] p.). Title of exhibition: Damn tired of being a slave.
Cutaneous T Cell Lymphoma (Mycosis Fungoides) in Blacks
Hong, In Soon, Johnson, Gregory, Kovi, Joseph
Between 1954 and 1980, 11 patients with cutaneous T cell lymphoma (mycosis fungoides) were diagnosed at the Howard University Hospital. There were five males and six females, all of whom were black....
