While a mobile phone or PC is traditionally controlled by only one user, many players come together in a networked household, some of whom even want to control devices simultaneously. Researchers from the Horst Görtz Institute for IT Security at Ruhr-Universität Bochum, together with colleagues from the University of Chicago and the University of Washington, […]
Secret Messages for Alexa and Co
A team from Ruhr-Universität Bochum has succeeded in integrating secret commands for the Kaldi speech recognition system – which is believed to be contained in Amazon’s Alexa and many other systems – into audio files. These are not audible to the human ear, but Kaldi reacts to them. The researchers showed that they could hide […]
New Sensor: What Goes On Inside Snow Avalanches
A new radar sensor grants insights into the processes inside snow avalanches. It was developed by a team of engineers at Ruhr-Universität Bochum (RUB) headed by Dr Christoph Baer and Timo Jaeschke, in collaboration with colleagues from Innsbruck and Davos. The measuring system has been installed at a test slope in the Swiss canton Valais, […]
Virtual Reality Making Construction Sites Safer
Bochum-based researchers are aiming to make construction sites safer with interactive virtual reality training courses. The team led by Prof Dr Markus König from the Institute for Computation in Engineering at the Ruhr-Universität Bochum is developing suitable technology to make it possible to experience sources of danger virtually. It is intended to help occupational health […]
Assembling Micro-Components With Laser Tweezers
A team of engineers headed by Prof Dr Cemal Esen from the Applied Laser Technologies lab at the Ruhr-Universität Bochum develop microscopic components and assemble them to larger objects with the aid of laser tweezers. They are thus establishing methods that one day may be utilised to manufacture machines in dimensions of a few micrometres. […]
New Tech for Land Mine Detection
In Colombia, large areas are teeming with mines that are almost impossible to detect with traditional methods. In collaboration with partners from South America, engineers at the German Ruhr-Universität Bochum and Technical University Ilmenau are developing a new mine clearance technology, based on ground penetrating radar. In the long run, they are aiming at creating […]
