SOG Coupled Biology & Physics Model of Deep Estuaries

SOG is a research model developed by Dr. Susan Allen's coastal oceanography group in the Department of Earth and Ocean Sciences at the University of British Columbia. If you are interested in the model check out Susan's publications, and if you are interested in collaborating on the code, contact Susan and maybe something can be worked out.

I did a major refactoring of the codebase during our sabbatical in 2006 and I continue to provide software engineering support for its development, and occasionally work on improvements and new features. I maintain the SOG version control repository, and the SOG buildbot cluster that we use for regression testing.

SOG is also the concrete, non-trivial example that I use to think about and experiment with automated software testing in the context of scientific computation. Sadly, apart from the buildbot regression testing, I haven't come up with anything that makes me happy enough to share.

Proprietary Projects

I have developed a number of software tools for my employer, Nordion:

• I-123 Datalogs

  A data logging system that monitors the operation of 3 production systems that produce I-123 radio-isotope via proton bombardment of enriched Xe-124 gas. Sensor data and active device states are logged from PLC in a MySQL database. A PHP web application provides trend graphs and status reports to users.

• IsoInfo

  A web application that provides planning, prediction, and data logging tools for production of Sr-82 via proton spallation of natural Mo targets. An irradiation model and web application implemented in PHP provide tools to plan irradiations to meet production demands, to analyze irradiations in progress, and to provide a basis for production yield calculations. Beam on target data is collected nightly from the TRIUMF 500 MeV cyclotron data logging system, stored in a MySQL database, and used in conjunction with the planned beam schedule to drive the irradiation model.

• ZSM

  A data logging system that monitors the state of a radio-pharmaceutical manufacturing cleanroom suite. Temperature, humidity, differential pressure, and non-viable particle counter data are logged from a collection of sensors by a LabVIEW application and stored a MySQL database. A TurboGears web application provides trend graphs, alert logging and investigation, and sensor calibration management to users.

• Minerva

  A quality management system web application that manages quality system form data in conformance with various standards for pharmaceutical manufacturing. Minerva provides form creation, routing, and tracking functions with electronic signatures, as well as quality system performance metrics, and full-text searching. The web application is built on the Pylons framework, and CouchDB is used to provide the data persistance layer.
