For a while now I have been working on migrating this blog to a personal domain on a server under my control. The time has come, and I’ve completed the migration of this blog to the following domain:
I have transfered the content and comments from this blog to the new domain, but I’m not sure if the subscribers to this blog will also be transfered. So just to be safe, if you are subscribed to get updates from this space, make sure you go to the new domain above and re-register. This way you’ll be certain to get new posts as email newsletters.
Otherwise, if you occasionally visit this blog, I wanted to let you know, that there will be no new posting on this space. I will leave it like this for a few weeks, after that I will be redirecting this domain to the new one, and deprecating it’s use. For now I think I will continue to use the email addresses for this domain, so the email -if you are using it- stays as it is for now.
I hope to see you all in the new blog space.

The primary focus as a Seismic Survey Specialist is the identification of tidal current patterns in seismic surveys and to exploit them in order to optimize sail line selection in 4D surveys. The feather data – i.e. the bearing of the seismic cables to the course made good of the vessel – collected can be analysed for hidden patterns. These patterns can help with the forecasting of tidal currents for subsequent surveys.
The following is the preliminary draft of a report I performed on the usage of statistical packages to conduct pattern analysis. Feel free to comment on any aspects of this work.
Identification of clusters in univariate data
The current report exhibits the clustering of Gaussian mixtures in univariate data using R to perform the processing. It was identified and postulated (initially by Ewan Nicolson) that certain distributed data might be produced by mixtures of Gaussian Normals when collected over a time-period. Certain normal distributions began to emerge when looking at feather data [see Figure 1].

The poster I had submitted to NVidia, explaining the work I did during my thesis, has been added to the roster of posters to be presented at the 2013 GPU Technology Conference in San Jose, CA. Unfortunately due to time limitations to getting a visa, and the cost of flying to San Jose, I will be promoting my poster in absentia, if that makes any sense!
You can see the rest of the participants in the Finance category, as well as my poster at this URL:
Thanks again to everyone that helped me bring this work to completion. They are all mentioned in the acknowledgments section of my thesis.
