A large part of my thesis work involves making models of DNA in a computer. The idea is that we make a model of DNA, shoot it with a whole bunch of radiation, and see how many times the DNA breaks. And DNA breaks are worth quantifying as they are one of the origins … Continue reading Building DNA for Monte Carlo physics simulations
I recently wrote a little post about a colour recognition plug-in I wrote for OpenCFU. To better tell the difference between colours, I transformed the RGB values in the image into their corresponding L*a*b* so that I could use a reasonable measure of colour difference. With that metric, this image shows the colours in the … Continue reading Colour Perception and the Mysterious Fourth Cone Pigment
In my PhD work, I've had to count a lot of dots on Petri dishes. It is a pretty mundane task but still very important. The majority of dishes I see look something like this: Each dot is a colony of E. coli bacteria, and there are two strains grown there in competition with each … Continue reading Identifying the colour of bacterial colonies using DBSCAN in OpenCFU
