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.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
