Context
|
TNO and GeoDelft are major
participants in the IJkdijk (http://nl.wikipedia.org/wiki/IJkdijk) project. By
destroying 80 (!) dikes equipped with sensors, sensor technology and scientific
models for dikes are developed, leading ultimately to an effective early
warning system. This research project will investigate the optimal signal
processing configuration of sensors that measure acoustic activities in dikes.
For this purpose a dike has been equipped with two microphones that are
placed in the ends of a long hollow tube in a dike. Data from this system
will be multicast over the internet. UvA will be
one of the subscribers. Most, but not all, research will be done at UvA. The student(s) working on this project will be
expected to participate in implementing experiments at the test facility, and
to collaborate with other researchers in the actual dike breach experiments.
As a result, this project will gain insight in the application of (acoustic)
sensor technology for the detection of dike failures. |
Research Questions |
In this master thesis project a signal processing
system for dikes is developed that answers the following questions: 1) What observables (and hence signal processing)
are useful for the measurement and analysis of acoustic activities in dikes ·
as a function of external (weather, canal)
conditions (e.g. is there more noise between 1000-and1500 Hz if the humidity
in the dike is higher) ·
when the dikes is being destroyed 2) What is the potential of external acoustic
sources to determine the condition of the dike (e.g. echoscopy
to see fractures / water levels) In addition the following question should be
addressed 3) Which design patterns exist for hard and software
architectures that process acoustic signals from dikes? |
