Reagan, MT; Moridis, GJ; Keen, ND; & Johnson, JN. (2015). Numerical simulation of the environmental impact of hydraulic fracturing of tight/shale gas reservoirs on near-surface groundwater: Background, base cases, shallow reservoirs, short-term gas, and water transport. Water Resources Research, 51(4), 2543-2573. doi: 10.1002/2014WR016086. Lawrence Berkeley National Laboratory: Retrieved from: http://www.escholarship.org/uc/item/4426c67m
Hydrocarbon production from unconventional resources and the use of reservoir stimulation techniques, such as hydraulic fracturing, has grown explosively over the last decade. However, concerns have arisen that reservoir stimulation creates significa

MeshVoro: A three-dimensional Voronoi mesh building tool for the TOUGH family of codes
Autor: Chris H. Rycroft, Katie L. Boyle, Craig M. Freeman, George J. Moridis, M. T. Reagan, Jeffrey N. Johnson
Publikováno v: Computers & Geosciences. 70:26-34
Few tools exist for creating and visualizing complex three-dimensional simulation meshes, and these have limitations that restrict their application to particular geometries and circumstances. Mesh generation needs to trend toward ever more general a

Data Elevator: Low-Contention Data Movement in Hierarchical Storage System
Autor: Suren Byna, Bin Dong, Prabhat, Noel Keen, Jeffrey N. Johnson, Kesheng Wu, Hans Johansen
Publikováno v: HiPC
Hierarchical storage subsystems that include multiple layers of burst buffers (BB) and disk-based parallel file systems (PFS), are becoming an essential part of HPC systems to address the I/O performance gap. However, the state-of-the-art software fo

A cartesian grid embedded boundary method for the compressible Navier–Stokes equations
Autor: David Modiano, Jeffrey N. Johnson, Phillip Colella, Björn Sjögreen, Xinfeng Gao, Daniel Graves
Publikováno v: Commun. Appl. Math. Comput. Sci. 8, no. 1 (2013), 99-122
We present an unsplit method for the time-dependent compressible Navier–Stokes equations in two and three dimensions. We use a conservative, second-order Godunov algorithm. We use a Cartesian grid, embedded boundary method to resolve complex bounda

Developing and managing individualized studies programs: Some guidelines
Autor: Howard L. Peterson, Jeffrey N. Johnson
Publikováno v: Alternative Higher Education. 2:257-265
This paper presents eight guidelines that educators should follow in developing and managing undergraduate individualized studies (contract learning-type) programs. The guidelines fall under the headings (1) supplying rationales, (2) focusing on the
