Well its been a long time since my last post, but I do have a relatively good reason: I was finishing up my PhD thesis. The good news is that I’m now done and graduated! I’m hoping I’ll have a bit more time to blog and continue working on side-projects that I had to put on-hold while finishing up. My plan for the next few months is to finish up here in Maynooth, (unofficially) start some post-doc work, and finish/get going on several papers on my PhD research. I’m also going to try to learn Bayesian statistics, fiddle about with some visualizations I’ve been working on, and start getting back into QGIS and Python development again
In the mean time, I’ve put together a fun little visualization of my PhD thesis in the form of a word-cloud.
For part of a traffic simulation project I am currently working on we need country-wide road network data for Ireland. In the past, getting decent road network data for an area this large was quite a task (not to mention expensive and time consuming), however, with OpenStreetMap we have access to this type of data instantly, and for free! In order to download full country coverage all at once, all I had to do was turn to this extremely useful site, which provides links for daily excerpts of OpenStreetMap data for any country in Europe plus several non-country regions such ...
In a recent post, I mentioned that I was testing the stability of clusters generated from a modified network partitioning algorithm using bootstrap resampling techniques. I also mentioned that I was doing this in R, using the very nice foreach package published by REvolution Computing. To show just how nice this package is, below is a minimal example of bootstrapping a network partitioning algorithm which takes advantage of a multicore processor:
Besides the obvious: “It’s not open source!”, I’m also not making the switch from Zotero to Mendeley for my academic reference management needs due to the answer to this question on the Mendeley FAQ page:
Is Mendeley free?
The straight answer would be yes and no. Yes, it’s free, because: Everything you get when you sign up to Mendeley is completely free and will always remain free - including the features described in What is Mendeley?
No, it’s not completely free, because: At a later point in time, we will expand upon the existing features and introduce ...
Many natural and human systems can be represented as networks, including the Internet, social interactions, food webs, and transportation and communication flows. One thing that these types of networks have in common, is that they can each be represented as a series of vertices (or nodes) and edges (or links). This blog entry presents a nice description of networks, highlighting the differences between various network types (directed, undirected, weighted, unweighted, etc.).
My article “Spatial-temporal patterns of snow cover in western Canada”,
has now been published on-line with The Canadian Geographer.
At this stage, only the proof copy is available online.
The article is now officially published, and can be cited as:
