Somewhat belatedly, I’m posting a summary of my thesis on this blog. I’ve copied both the lay summary to explain the work in more general terms, together with the more technical abstract of my thesis.
Somewhat belatedly, I’m posting a summary of my thesis on this blog, to summarise what I spent over 3 years of my life working on. I think after finishing my corrections I had had enough of writing for a while. I also started my new post at the university around the same time, so was busy with that, and somewhat lost interest in this site. I’ve copied below both the lay summary to explain the work in more general terms, together with the more technical abstract of my thesis. If you are really interested, the full thesis is available in the Edinburgh Research Archive. Continue reading “My Thesis: Combined wave-current scale model testing at FloWave”
With the Earth having completed another billion kilometre long orbit around our sun, and our arbitrary calendar changing year, it’s time for my annual look back at the numbers of the previous year. I took nearly 11k photos, and walked 4.5 million steps covering almost 3600 km. This analysis is probably mainly of interest to me, but I am sharing it anyway.
The title or this paper is a bit of a mouthful, but actually it covers a relatively simple subject: the errors that may arise if the water depth is not scaled consistently with other parameters when tank testing devices, particularly those designed to harness power from waves.

This paper was published in the Ocean Engineering journal in October 2017. It was a joint piece of work with fellow IDCORE researcher at FloWave, Sam Draycott, building on our separate areas of research. In it, we demonstrate the capability of the FloWave facility to generate complex wave-current conditions, and also highlight the importance of considering even relatively low tidal currents when testing wave-energy devices.

I finally finished my thesis, and handed in a copy for examination a couple of weeks ago. I’m now catching up with all the things I’ve not done over the past months, including sleep and updating this site.
The actual process of handing in the thesis for examination was something of an anti-climax. Continue reading “Thesis finished”
As I mentioned previously, I am writing my thesis using the LaTeX markup system, and thought I would put together a few words on my experience and things I have found. This includes formatting tables, including acronyms, and larger landscape figures/tables. I am sure there are many other ways to to achieve the same result, but these are the ones I have found to work.
After nearly three years of research, I have started the long and arduous process of writing up. I am going to use LaTeX to compile my writing, mainly because it makes it easier to make beautiful looking documents. Also word processing packages have a nasty habit of corrupting the formatting, and make numbering of equations difficult.
In January I pulled together my notes and various bits of writing into a first semblance of a structure. I had started most of the writing in Word, but using the LibreOffice export plugin I have mentioned previously, I was able to convert this to basic LaTeX fairly easily. I have since added in plots from MATLAB, which I had been avoiding inserting into Word, as it doesn’t handle images in a sensible vector format (e.g. SVG, EPS, PDF). Continue reading “And so the thesis writing begins”
With the new year upon use, time for my annual analysis of the year just past. I’ve continued logging my physical activity and travel, with a few more categories. In 2016 I took approximately 4.5 million steps, covering over 3 000 km, and I cycled a further 1 300 km. Continuing the trend from my previous comparison, this is slightly more walking but less cycling than the previous year, possibly as I have started running this year.
