The ASU award-winning Java-DSP software
package has been adopted in a 3-year collaborative NSF project in Earth
systems signals research involving PIs Linda Hinnov from Johns Hopkins,
Andreas Spanias from ASU, and James Ogg from Purdue. This project,
which started in August, 2007, was funded by NSF’s EAS Division for
$575K, with an emphasis on acquisition of paleoclimate signals from the
sedimentary rock record. J-DSP is a visual programming environment
developed by Andreas Spanias of Electrical Engineering and his graduate
students for instruction in digital signal processing. J-DSP won
two IEEE awards and was rated and recognized by the UC-Berkeley NEEDS
committee as one of the top three non-commercial software packages
J-DSP will be extended into a J-DSP/Earth Systems Edition
(J-DSP/ESE) for use by earth scientists to process and interpret Earth
system signals. J-DSP was previously used for multimodal wireless
sensing research and for DSP education technology projects. A new
family of functions created for earth data relating to applications in
geology, exploration, sustainability, hazards, and environmental
assessment are bundled in our new J-DSP/ESE. The functions are focused
on representing earth systems data in an intuitive manner, and allowing
students to experiment with different functions by taking advantage of
the powerful visual programming environment of J-DSP. This new system
is useful in earth systems related courses where students can use
J-DSP/ESE to analyze data and extract information that relates data to
events, processes and other dynamical pheonomena.
Summary of progress and accomplishments made in this project in the years 2009 and 2010 is listed here.
The standalone J-DSP/ESE software application developed in 2011 is available here.
We have developed three tutorials in order to help students,
practitioners, and researchers understand some aspects of modern and
past climate change using the application. The tutorial guides and
the supporting data files can be found
A presentation on the capabilities of the online J-DSP/ESE software was delivered in 2011 and the video is available here.
