Videos now on Youtube play list
As the videos on Kiriakos's web site have now gone it is easier to find them on the Youtube play list.
The first one has about 11,000 views suggesting possibly people were looking for something else that EIT stands for. Either that or EIT is much more popular than I thought but after teh first video they were put off. Who knows. Wikipedia has a list of meanings of EIT. Maybe Everything Is Terrible! (well it is illposed) Or Engineer In Training (EIT is great for training engineers).

Isaac Newton Programme
The Isaac Newton Institute in Cambridge has a programme this half year on Inverse Problems and the videos of the introductory course are on line this week.
The first workshop is on this week and will be on line soon. There are some things
relevant to EIT reconstruction in this week as well

Break for now at least
Andy has not yet managed to make an EIDORS video a tutorial. I suggest we take a break for now. But I am open to suggestions. Reply in comments with things you would like me to talk about, or find someone else to talk about. Applications springs to mind for one thing. Some of us are learning about lung EIT and lung mechanics. Others geophysical EIT.

EIDORS playtime at 11 today
Instead of a lecture today I have booked the small computer cluster downstairs in the Alan Turing Building. I intend we shall have a play with EIDORS. I am currently faffing about getting netgen etc working on windoze!

No lecture tomorrow
I had been planning a demo of EIDORS but as my laptop has died it is proving too difficult to set up. Locals may be interested in The Numerical Analysis and Scientific Computing Seminar tomorrow (Friday 5th Nov)
Paul Childs (Schlumberger Cambridge Research)
Challenges in seismic imaging
3pm Frank Adams 1 Alan Turing Building

Lecture 6 Sharp changes
This lecture concentrated on reconstruction algorithms for sharp changes. I concentrated mainly on Monotonicity method and Factorization. I referred to the slides for a talk given in Korea in 2006, so you will need this open to follow as it is not easy to see on the video.
There are references at the end of the slides, but for factorization method there are some more recent work that might be a better place to start.
I did not go in to TV that much but there are more details on the slides.
Videos All in one file, Or in chunks part 1, part 2, part 3, part 4.
Here is the web interface Brühl's factorization code.

Lecture 5: drive and measurement patterns
This was a bit unplanned but following a phone call to Andy Adler on Thursday I decided to talk about drive and measurement patterns, so it if it seems a bit rambling and unplanned it was.
Videos here part1, part2, part3,part4.
Some links mentioned in the notes
