Researchers from all across the world are faced with the great challenges involved in visualising “big data” – in particular, where image resolution and image size are concerned. The Institute of Visual Computing at the Bonn-Rhein-Sieg University of Applied Sciences has put one of Germany’s largest, interactive and ultra-high resolution display panels – including the corresponding PC cluster – into operation today.
“We live in a world in which the majority of work processes are aided by computers,” said Professor Dr André Hinkenjann, Director of the Institute of Visual Computing. “These work processes continuously generate vast amounts of data that need analysing and evaluating.”
At this point the three metre by seven metre display panel sets new standards in visualising “big data”. “We are capable of visualising up to 72 megapixels using the 35 screens of the display panel, which enables us to generate detailed two- and three-dimensional images and to conduct interactive analyses for various areas of research,” Hinkenjann added.
Three computers - including nine graphics cards - are involved in digital image computation behind the display panel. However, the computational power provided is not sufficient to visualise complex results, “To enable true-to-scale visualisations of such products as high-quality cars, the computers are connected to a cluster of twelve additional computers,” Hinkenjann added.
The latter calculate the data capacity needed to visualise the challenging images; they then transmit them to the three computers at the display panel.
To maintain the speed needed for data transmission, we have also established a network with a transmission rate of up to 60 GBits/s,” André Hinkenjann explained, adding, “The display can be used in the research areas of computer science, maths, geography, biology, chemistry, medicine or materials science. However, some basic questions also remain to be answered.
For example, one may wonder how computer users can interact with such large display panels in a user-friendly manner.”

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
