Since Rita planned to do some more swimming in the Doubs in the near future, I decided to fix the legs at the bottom of our swim ladder. These legs are meant to hold the ladder out from the hull of the boat when someone is climbing back up to the boat. However, they have a nasty habit of folding inwards, putting more stress on the hooks at the top of the ladder that go over the gunwales. So I installed a brace that would hold them out, but could be removed to enable the legs to be folded inwards when the ladder is stored on deck. We'll see how it goes when Rita next needs to use the ladder.

Rita made a trip to the shops and the post office in mid-morning, before we left port at 1115h, headed north. We enjoyed a gentle cruise north. almost entirely on the river, before arriving at Delux around 1530h, where we moored opposite the tall chimney on the north side of the town.

The weather was beginning to turn hot, but with a developing breeze. During the late afternoon, I noticed that a damselfly had decided to pick our cabin top as a good place to die. The patterns in its wings, and the shadows of its wings on the deck, made a interesting sight in the late afernoon sun.

That evening, I continued working on my Excel program to count word frequencies. The reason for this exercise is that I get email notifications from a group called academia.edu, alerting me to citations of the various publications I have written in years gone by. They do this by sending the citing reference, and the details of the cited publication, based on my name (or a variation thereof) appearing in the authors of the cited paper. However, only about 3% of these citations are actually mine (there are lots of other A.J.Richardsons publishing papers). As a result, I have to sift through a lot of irrelevant citations in order to find mine. It occured to me that the search could be a lot more efficient, if they developed a score based on the words in the cited publication, based on the frequency of those words in those papers which I have already identified as being mine. For example, "Richardson" would appear in all the cited publications (by definition), but my publications would have a relatively high probability of having words like "transport", "traffic", and "survey", and a relatively low probability of words like "plankton", "accounting" and "octopus". My publications would also have a high probability of having the surnames of other authors with whom I have written papers. If they implementation a filter based on such a scoring system, I could save a lot of time that is currently wasted at looking at irrelevant citations.
