The Computational Infrastructure for Nuclear Astrophysics
The Computational Infrastructure for Nuclear Astrophysics is a platform-independent suite of computer codes that
is available online at http://www.nucastrodata.org/
infrastructure, which streamlines the inclusion of the latest nuclear
physics data in astrophysics simulations. The user-friendly, web-deliverable Java interface to a server-side database and Fortran simulation codes
enables users to:
- upload their nuclear data
- perform simple data evaluation tasks
- create reaction rates from cross sections and s-factors
- create, access, merge, and manage libraries of cross sections and rates
- comment on rates and view comments of others
- share rates with others or keep them private
- export rate libraries
- setup and run post-processing element synthesis calculations with new rate libraries
- visualize the simulation results with 1d plots and 2d animated nuclide charts
Some of the newest features include:
- a mass model evaluator which enables theoretical mass models to
be compared to each other and to experimental data - the capability to render movies and export for use in presentations
- the ability to quickly compare simulation results with different libraries
- commenting on rates and libraries with an email-type interface
- upgraded tools for parameterizing reaction rates
- r-process and nu-p process simulation results
- visualization of reaction flux and time derivatives of abundances
Big Bang Online
In the standard model of Big Bang Nucleosynthesis (BBN), the creation
of the light elements 2H, 4He, and 7Li in the early universe depends on
the rates of thermonuclear reactions as well as on the baryon-to-photon
ratio. This ratio can be constrained by comparing each of the primordial
abundances of 2H, 4He, and 7Li (inferred from present-day observations)
to those predicted by BBN theory. Disagreements between these constraints
(e.g., from 7Li) and the complementary baryon-to-photon ratio constraint
derived from Cosmic Microwave Background Radiation (CMBR) observations
can indicate, and constrain, potential new physics beyond the standard
model. The Big Bang Online software suite, which is a set of web-deliverable Java interfaces in conjunction with a server-side database and Fortran simulation codes, allows anyone to create, run,
visualize, and share custom Cosmology calculations using Big Bang Nucleosynthesis
theory. It is available online at

QUALCONN: Drilling Engineering Association Project 151
QUALCONN is a set of software tools used to explore an integrated reliability test database for casing and tubing connections that addresses design engineering, purchasing, quality, operations, installation and management needs for the oil drilling industry. QUALCONN, originally written as a PHP-driven website in conjunction with a MySQL database, is being converted to a client/server application using a web-delivered Visual C# graphical user interface connected to a MySQL database via PHP.
British Petroleum Advanced Probabilistic Tubular Design Toolkit
Toolkit is a set of software tools used to explore a large database of oil drilling pipe casing properties and simulate pipe collapse and burst scenarios. Toolkit, originally written as a Visual Basic and Microsoft Access desktop application, is being converted to a client/server application using a web-delivered Visual C# graphical user interface connected to a MySQL database via PHP.
Interactive Conceptual Model
The Interactive Conceptual Model (ICM) is an interactive web tool that facilitates literature retrieval based on conceptual models for the EPA/NCEA Causal Analysis/Diagnosis Decision Information System (CADDIS). The ICM was developed using Adobe’s Flash CS3 with ActionScript 3 and Adobe ColdFusion 8 in conjunction with an XML database. The ICM is available online at http://cfpub.epa.gov/caddis/icm/ICM.htm.
RSim: A Regional Simulation to Explore Impacts of Resource Use and Constraints
An environmental decision support system designed specifically for military
installations, which have a unique set of ecological issues. It explores
the impacts and constraints of resource use by projecting future land
cover changes and their impacts on environmental conditions by allowing
users to calculate and visualize these projections through a platform-independent,
user-friendly Java software package. RSim is available online at
http://www.esd.ornl.gov/
programs/SERDP/RSim/.

Developing Reusable Components in Flash MX
Developing Reusable Components in Flash MX is a highly interactive Flash module that demonstrates by stepwise implementation of working examples how to create, install, and document Flash MX Components. It is presented in such a way that it should be accessible to anyone having a basic familiarity with Flash and ActionScript. Developed for educators and funded by a Project SET grant provided by the Educational Technology Collaborative at the University of TN, Knoxville, this module is available online at http://edtech.tennessee.edu/set/2003/lingerfelt.shtml.
REACLIB aLIVe!: REACLIB Rate Library Interactive Viewer (Master's Thesis)
Nucleosynthesis occurs in such diverse astrophysical phenomena as ordinary stars, like our own Sun, supernovae, novae, X-ray bursts, and the Big Bang. Large sets of nuclear reaction rates for hundreds of seed isotopes are utilized in simulations of these nucleosynthesis processes. A cross-platform, Java software package called REACLIB aLIVe! has been developed with intuitive graphical interfaces and interactive controls to produce custom one-dimensional plots of reaction rates. The software offers nuclear astrophysicists the capability to rapidly display any of 8000 nuclear reactions in the library, as well as to add new reaction rates and compare them to ones in the library. The plots produced by the software may be exported in the postscript format, which is easily edited and incorporated into papers, presentations, and websites. The accompanying Master's Thesis is available at http://etd.utk.edu/2002/LingerfeltEric.pdf.
