ICT role in 21st century education and its challenges
Ph semat overview
1. ACEDP – River Health & E-flows
Brisbane, December 2009
2.
3. ! " Separating background variation from real change
! " Reducing the need for extrapolation & interpolation
! " Capture events – continuous data collection
! " Need to cross ecological scales in data collection
(Satellite to ground to satellite)
! "Need to dialogue with data collection system – react
remotely.
! "Build overall confidence in the models & decisions
made based on the data.
4.
5. !" A wireless sensor network “system”
! "“Smart”
! "Distributed
! "Low cost
! "Robust
! "Adaptable
! "Scalable
! "Eco-friendly energy
! " New
platform for environmental
monitoring & Management support
6.
7.
8. ! " Taking
multidisciplinary approach to produce a new
generation of integrated technologies –
not a one-man project
seamless from data collection to application
! " Phased R&D
Evolution rather than blue-sky invention
Proof of concept to viable product
! " Applicable
beyond the environments being used for
development
12. Pros:
! " Cheap
! " Insensitive to acoustic noise
! " Low sensitivity to natural obsatcles
Cons:
! " High attenuation at high
frequency
! " Carrier freq must be ELF/VLF:
consequent low bandwidth/
comm speed
