DESCRIPTION:Prof. Paul G. Flikkema\, EECS Department\, Northern Arizona 
 University\nAbstract\nNew applications are motivating and informing the de
 sign of sensor/actuator networks\, and\, more broadly\, research in cyber-
 physical systems (CPS). One CPS application domain of growing interest is 
 ecological systems\, motivated by the need to understand plant survival an
 d growth as a function of genetics\, environment\, and climate change. For
  this effort to be successful\, we will need cyber-eco systems to infer da
 ta-driven predictive models of plant growth dynamics in response to climat
 e drivers that allow incorporation of uncertainty. I will present the arch
 itecture of a cyber-eco system for precise fine-scale control of irrigatio
 n in an array of geographically-distributed outdoor gardens on an elevatio
 nal gradient of over 1500 m\, allowing design of experiments that combine 
 control of temperature and water availability. The distributed in situ inf
 rastructure is based on a modular\, parallel-processing node hardware desi
 gn allowing real-time processing and heterogeneous nodes\, energy-aware ha
 rdware/software design\, and a networking protocol that builds in trade-of
 fs between energy conservation and latency. Throughout\, we emphasize the 
 changes in system architecture required as missions evolve from sensing-on
 ly to sensing\, inference\, and control. We also describe our developmenta
 l implementation of the architecture and its planned deployment. Future ex
 tensions will likely add negative control of precipitation using active ra
 in-out shelters and additional plant-level control of air or soil temperat
 ure.\n\nBiography\nPaul G. Flikkema is a Professor of Electrical Engineeri
 ng in the EECS Department at Northern Arizona University.  He received th
 e Ph.D. from the University of Maryland\, College Park.  His research and
  education interests include wireless networking\, sensor/actuator network
 s\, embedded systems\, inference of model structure\, parameters\, and sta
 te in complex systems\, and the design of engineered systems for understan
 ding these systems.
