Calculating the area of the intersection of a polygon and a circle of the same area

How hard could that be? Quite hard it seems!

region selection

I am reselecting the regions to use for these tests. I now randomly select from the population within each band up to a maximum. Some bands have only a few members, in which case I end up selecting them all in that band.

Underlying

Interesting. I suppose the spike is because all the small places are neigbourhoods of Sheffield, whereas in the other region sets there is a random spread.

normalised, by region size

results

I appear to have some results to look at. We had a good supervision meeting where we discussed how to present them to best effect.

Slight change of plan

It is now unlikely that I will go away for any length of time over the summer. This is better in many ways because I will have all the resources I need to make a good job of this PhD to hand.

Writing begins in earnest

I have started to structure my PhD. This is involving lots of reading because I forgot why certain citations were used in the transfer report. The thesis document looks nothing like that now and I must be certain that the cites are relevant and not misquoted. Doing well so far, but re-reading takes time. There are also later/more relevent ones (eg Garbin and Mani's investigation of explicit discriminators etc).

I am preparing to move the whole process to the other end of the country on Sunday. Actually this might be a good time for a change of scene, these 4 walls here are getting boring!
