The latest outputs from researchers, alumni and friends at the UCL Centre for Advanced Spatial Analysis (CASA).
I’ve been modelling the interconnected nature of the global economy by simulating a reduction in demand for various sectors in various countries. It’s a very simple little piece of analysis: What would happen if the demand for a given sector in a given country was reduced by a single US dollar? In answering this question […]

Riccardo Maria Pulselli from the Ecodynamics Group at the University of Siena has put his fascinating book on urban kinetics online. Click here to view. In it he demonstrates that cities are never in equilibrium, they are always changing, and … Continue reading →

Networks: aren’t they great? The sexiest modelling paradigm around at the moment and there are no shortage of social science researchers itching to jump on the bandwagon. Never one to drag my heels, I blogged last week about the attempts by me and my colleagues to bring network science into Economics, and included a fancy […]
Continue reading »If you click here you can see out paper on the analysis of London’s street network from the 18th century to the modern day. It was published this past week (12th August) in PLoS One and is open access, the … Continue reading →

Continue reading »This is more or less a repeat of my course at ASU earlier this year and although I peppered this with a lot more comment and discussion in terms of the actual presentations to graduates at Tel-Aviv University (TAU), most … Continue reading →
Continue reading »Suddenly the world seems to have woken up to the fact that we can treat cities as a science. More than 100 years ago, Patrick Geddes said ”Thus, in fact, appear the methods of a Science of Cities …..” in Cities in … Continue reading →
Continue reading »Note: this was previously posted at simulacra.info, but I am in the process of (re)organising my technical notes and tutorials. After giving up on Gephi (again, I really should learn), I decided it was time to get to grips with … Continue reading →
Continue reading »For the online course TechniCity, I have made a little video of Big Data and our Oyster Card project using data from the subway system courtesy of Transport for London, and courtesy of our researcher Dr. Jon Reades. The video … Continue reading →

Continue reading »It is a bit of a gamble to tell those who watch our CASA site that I have just started a new lecture course on Smart Cities that I am offering to graduates at ASU. A gamble because Smart Cities … Continue reading →
Continue reading »Here is a short one page missive from me printed in this month’s (January 2013) issue of Geographical (magazine) which argues the case for getting involved in these questions. Can’t find the online content (and we don’t seem to have … Continue reading →

Continue reading »After giving up on Gephi (again, I really should learn), I decided it was time to get to grips with Python and iGraph since I really need to produce multiple iterations of a graph. The matmos at CASA have, of course, been touting Python for ages, but I’ve just not had the time/incentive to install […]
