DESCRIPTION:Prof. David E. Rival\n16:00 – 17:00 – Prof. David E. Rival
 \nAssociate Professor\, Queen's University\, CA\n\nPushing the boundaries 
 of in situ Lagrangian flow measurements\n\nThe potential for clouds of dis
 tributed\, Lagrangian sensors in complex environmental flows\, when couple
 d with network-science tools\, offers a myriad of fresh opportunities to c
 haracterize key transport processes critical to modeling (and adapting to)
  climate change. For sake of illustration\, both passive (e.g. drifting se
 eds) as well as active (flying/swimming) sensing platforms\, are described
  here. Some examples of optimal sensing in flying/swimming\, based on prop
 rioception\, will be touched on before embarking on a description of a nov
 el passive technique using nothing other than air-filled soap bubbles to f
 ollow the flow. Here\, we show how a single-camera perspective can be used
  to track centimeter-sized soap bubbles in three dimensions by not only ev
 aluating the bubble-center location but also the bubble-image size itself.
  Of course with such Lagrangian measurements come challenges associated wi
 th identifying flow features with inherently sparse data. Existing approac
 hes\, based on graph theory\, will be reviewed before a new technique usin
 g multi-scale recurrence networks will be tested on a series of canonical 
 problems.\n\n\nShort bio:\nDr. Rival leads a large research group at the i
 nterfaces between experimental fluid dynamics\, data assimilation\, networ
 k science and bio-inspiration. In 2020\, Dr. Rival was awarded a one-year 
 Alexander von Humboldt research fellowship to conduct research on advanced
  sensing techniques in Munich. Prior to joining Queen’s\, Dr. Rival comp
 leted his doctoral studies on the aerodynamics of dragonfly flight at TU D
 armstadt\, worked as a postdoctoral associate at MIT on shape morphing in 
 nature\, and held a research chair on atmospheric sensing at the Universit
 y of Calgary. The lab is involved in a number of international research co
 llaborations sponsored by\, for instance\, AFOSR and NATO\, and has been f
 eatured on David Suzuki’s The Nature of Things as well as on the Discove
 ry Channel’s Daily Planet show.\n
