World Record Challenge

Do you remember the time of the dial-up internet? If you do, I bet you have this "Eeeee-aww-eeee-aww-eeee-aww-eeee-aww" sound in your head. And you think these days are long gone, with fibre optic and 4G available almost everywhere. However, this is really not the case once you leave the shore and set to the ocean. After a few nautical miles, cellular data becomes incidental and gradually using satellite communication is inevitable. A mostly unknown but large population of men and women are working at sea for eight to ten months of the year, only seeing their families on rare occasions. Consider also fishermen and all those who defend our coasts against the multiple kinds of trafficking, including any type of goods, and even human trafficking, and who are fighting to protect the marine ecosystem. And all they have in terms of communications are two possibilities: satellite, or cellular systems such as the 3G used by your mobile phone. SeaFi offers a new third option. SeaFi facilitates the creation of private networks in ports and coastal areas by establishing connections between lighthouses, maritime wind turbines, or offshore drilling platforms and vessels at sea. These networks are used to connect the ships and their crews, as well as the data collection buoys (weather, tides) for example. 

In 2018, using the SeaFi technology invented by Arnaud Disant, a scientific world record for the longest wireless internet communication at sea was established: 19.4 nautical miles (35.92 km). This year we are challenging this record. You might ask - why do you want to challenge your own record? Well, competing with yourself is the ultimate form of self-improvement and the one challenge that never ends. When we compete with ourselves, we focus on our own progress and growth, and we set our own standards of excellence. While striving to be better than we were yesterday, we push ourselves to new heights and achieve things we never thought possible. We have already been asked how to contribute to our effort. A fundraiser has been set up. Your contribution will go directly towards chartering the local cargo supply vessel that is essential to venture offshore beyond 19.4 nautical miles, thus making a positive impact on our community. If you would like to contribute, please follow this link

UCD Wave Group research blog

Maths with creativity...

The UCD Wave Group has researchers from all over the world. Dr Leandro Fernández, who works on the RESOURCECODE project, gave a webinar in Spanish on Friday 12 June 2020, entitled "Datos meteorológicos y modelos de predicción global para zonas marítimas" and hosted by the School of Civil Engineering of Universidad Santo Tomás in Tunja, Colombia. The webinar is available on YouTube.

La UCD cuenta con un grupo de investigación dedicado al estudio de la dinámica de las olas oceánicas denominado 'Wave group', en el cual participan investigadores de diferentes países.  Uno de sus integrantes, el Dr Leandro Fernández, que actualmente se encuentra trabajando en el marco del proyecto RESOURCECODE, ha dado un Webinar en

Prof. Dias will co-chair the European Fluid Mechanics and Turbulence Conference (EFMTC2021) at ETH Zurich from June 20-24, 2021.

Due to the COVID-19 pandemic the EUROMECH council decided to combine the 13th European Fluid Mechanics Conference (EFMC13) and the 18th European Turbulence Conference (ETC18). ETC18 was originally supposed to take place in Dublin in August 2021.

This conference will bring together scientists from all fields of Fluid Dynamics.

The Wave Group projects involve a lot of numerical simulations, dealing in particular with extreme sea states, using nonlinear wave propagation models. ICHEC, the Irish Centre for High-End Computing, provides core-hours to three kinds of projects. Class A projects are intended for consortia concerned with high impact problems. Prof. Dias was successful with his Class A application. The project has been given 5M core-hours. It will start on 1 June 2020 and will last for a couple of years.

In these dark times, when good news is scarce, science always pushes the boundaries and offers hope…

The world record set by Engineer Arnaud Disant and his team in 2018 has now been officially verified: offshore WiFi transmission of 19.4 nautical miles off Cork harbour, “The longest ever attempted transmission between a vessel offshore and a lighthouse on a distant shore, without using satellite communication of cellular data like 3G or 4G…”

I am proud to have been a witness to the achievement of this record. A scientific paper will soon be published in the MTS (Marine Technology Society) Journal. 

Congratulations to Arnaud! Your record is fantastic news for marine data collection.

The 2020 SIAM Conference on Parallel Processing & Scientific Computing

Home to the world’s largest internet company as well as other renowned tech giants, Seattle seems like the perfect place for a meeting on high performance computing. This year’s SIAM Conference on Parallel Processing & Scientific Computing - SIAM PP20 for short - took place right in the centre of the rainy city.

Hundreds of scientists from all over the world met to discuss emerging issues in scientific computing. From best practices in benchmarking to reducing communications between processors and code reproducibility, some of which have been topics of interest for many years as anyone learning about David Bailey’s “12 Ways to fool the masses” (1991) in an introductory course on computing can probably attest to.

Of particular interest to
