A new book by David O’Sullivan and George Perry called Spatial Simulation: Exploring Pattern and Process (Wiley, 2013) is an important landmark text for all those involved in CA and ABM. I quote from the back cover:
“O’Sullivan and Perry have written a book that defines the key principles and methods that underlie modelling and simulation, building on ways in which the elements that make up our systems move, diffuse and grow. They succeed magnificently in producing a gentle, unassuming and convincing picture of how spatial models work and are validated. Essential reading for all engaged in this field”.
There is a very handy web site too called Pattern and Process where you can explore the book and its examples. Click here.
David was our first PhD student in CASA graduating 13 years ago, and he is just in the process of moving from Auckland to Berkeley where doubtless he will continue with his interesting approaches to complexity theory and cities which are encapsulated in this work.
At ECCS ’13 this morning, Elsa Arcaute, Lecturer in Urban Modelling in CASA, is talking about our work on city size using percolation theory which has analogies to Hernan Makse’s work on percolation and the brain. Click here for the programme and the paper in the Arxiv on which is it based. You can also see all seven of us from CASA who attended on the photograph of participants at ECCS the other day which is one the website but you will need a magnifying glass!
AESOP-ACSP is the joint European and American Associations of Planning Schools conference held this year in Dublin at UCD. The theme is resilience in cities and how planning might best respond to it. This is a popular term and is overtaking sustainability with respect to how planning might respond better to crises. This morning (18th July) i gave a keynote on this question alongside Susan Fainstein from Harvard GSD, where I concentrated on how we are measuring, understanding, and pre citing resilience and the extent to which city systems can ‘bounce back’ after various disruptions. My talk stitched together the work we are doing on the big data sets from London transport which look at disruption on various rail systems, on flooding from our Tyndall project n climate change in London, and on our need to understand how Great Britain is fractured across is regional space where we use percolation theory to figure out how the space divides in nations, regions and cities. here is the powerpoint as a PDF
