The control of modern infrastructure such as intelligent power grids needs lots of computing capacity. Scientists of the Interdisciplinary Centre for Security, Reliability and Trust (SnT) at the University of Luxembourg have developed an algorithm that might revolutionise these processes.
With their new software the SnT researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining. Their achievements, which the team headed by Prof. Yves Le Traon published in the International Conference on Software Engineering and Knowledge Engineering, earned the scientists a Best Paper Award during this event.
Modern infrastructure – from the telephone network and alarm systems to power supply systems – is controlled by computer programmes. This intelligent software continuously monitors the state of the equipment, adjusts system parameters if they deviate, or generates error messages. To monitor the equipment, the software compares its current state with its past state by continuously measuring the status quo, accumulating this data, and analysing it.
That uses a considerable portion of available computing capacity. Thanks to their new algorithm, the SnT researchers’ software no longer has to continuously analyse the state of the system to be monitored the way established techniques do. In carrying out the analysis of the system, it instead seamlessly moves between state values that were measured at different points in time.
“In particular the operation of distributed installations such as power grids of today will benefit from our programme”, says Dr. François Fouquet, managing the project at SnT with Dr. Jacques Klein: “In these smart grids, as they are referred to, many smaller individual components like solar cells, rectifiers, and other components must be monitored and controlled. For the investment and operating costs to remain economically acceptable, they have to be equipped with small, simple control units.” These kinds of small embedded microprocessors cannot continuously measure the system states, store the data, and evaluate it in real-time.
Thomas Hartmann, who is completing his doctoral dissertation as part of the project, explains the new approach by SnT: “Our software stores only the changes of the system state at specific points in time. In order to be able to correctly evaluate the current situation in the network, our algorithm automatically identifies suitable measure-ment values from the past. It therefore pulls the correct measurement values from the archive to carry out a correct analysis of the current state – thereby essentially jumping back and forth in time. That translates into an enormous reduction in computing overhead and thus an increase in computing efficiency for the same standard of security and dependability.”
The researchers next want to field test their process. As in the first part of the project, they are collaborating with Creos, the Luxembourg power grid operator and participant in the SnT Partnership Program “Thanks to this collaboration, our research has always remained in accord with corporate realities", says Prof. Yves Le Traon: “We are hoping our fundamental development work will trigger a jump in the technology of smart grids.”
About SnT: Launched in 2009 by the University of Luxembourg, SnT is an internationally recognised leading research institute that together with external partners establishes Luxembourg as a European centre of excellence and innovation for secure, reliable, and trustworthy information and communications technologies (ICT). In order to create a great impact, SnT follows an interdisciplinary research approach, taking not only technical aspects into account but also addressing business, human, and regulatory issues. SnT provides a valuable platform for interaction and collaboration between university researchers and external partners.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
