Attended a lecture this evening at Engineers Ireland by Jennifer Jennings, a data scientist at ESB (Irelands main Electric utility). She dropped some good understandings on us regarding ESB’s use of data analytics/data science/machine learning to solve problems of interest to energy utilities. Particularly of interest, was their approach to detection of partial discharges for power line fault detection. In …
Here is what Wikipedia has to say about Benfords Law: Benford’s law, also called the First-Digit Law, refers to the frequency distribution of digits in many (but not all) real-life sources of data. In this distribution, 1 occurs as the leading digit about 30% of the time, while larger digits occur in that position less frequently: 9 as the first …

Sparklines are the brainchild of Edward Tufte. They are those “intense, simple, wordlike graphics” that you sometimes find embedded in stock listings and such like. To help our installation team we have created a little application that runs on installer’s smart phones. This application is written in PHP and is designed to show live energy streamed from our Canary embedded …
Occasionally, we aim to publish something that has to do with how we implement our hardware and software solutions. Here is one of these “somethings”…. On one of our embedded devices there is the facility to automatically dispatch text messages in response to particular events. However, to protect against the possibility of the device sending out a storm of text …
It’s due to become one of the major political hot potatoes over the next couple of years, but many people don’t yet realise that Ireland has signed up to massive carbon reductions by 2020. In the 2007 Government White Paper, Delivering a Sustainable Energy Future for Ireland, a target has been set for a 20% improvement in energy efficiency across …
Yesterday, Liam Relihan, the CTO of ResourceKraft, a Limerick-based supplier of energy management systems warned that Irish businesses and government institutions were vulnerable to an ever larger collection of cyber attackers. He stated that “the Building Management Systems (BMS) and SCADA systems that have been deployed by Irish businesses and government bodies present an increasing attack vector for would-be hackers. …
