Creating a virtual reality classroom … School-age children could one day take a class on the moon — with the help of virtual reality, that is. With a $1 million National Science Foundation grant, a multi-university team of researchers will work to expand the possibilities of VR-based education over wireless networks. Led by Bin Li, Penn State associate professor of electrical engineering, the researchers will develop and implement a virtual reality system to create a personalized, collaborative VR platform for…
Researchers at TU Graz have modelled an AI system for automotive radar sensors that filters out interfering signals caused by other radar sensors and dramatically improves object detection. Now the system is to be made more robust to weather and environmental influences as well as new types of interference. In order for driving assistance and safety systems in modern cars to perceive their environment and function reliably in all conceivable situations, they have to rely on sensors such as cameras,…

Optimized approach simplifies underwater optical data links; could enable devices that transmit data and produce power. Although solar cells are typically designed to turn light into power, researchers have shown that they can also be used to achieve underwater wireless optical communication with high data rates. The new approach—which used an array of series-connected solar cells as detectors—could offer a cost-effective, low-energy way to transmit data underwater. “There is a critical need for efficient underwater communication to meet the increasing…
Researchers at TU Darmstadt are using HPC at the Leibniz Supercomputing Centre to develop a new approach for modelling turbulence in fluid flows. From designing new airplane wings to better understanding how fuel sprays ignite in a combustion engine, researchers have long been interested in better understanding how chaotic, turbulent motions impact fluid flows under a variety of conditions. Despite decades of focused research on the topic, physicists still consider a fundamental understanding of turbulence statistics to be among the…
Keeping the balance between quality, production efficiency and costs has always been difficult in the manufacturing of precision optics. To make manufacturing data usable for these purposes by creating a digital twin along the production chain for quick optimization is therefore the goal of the “EverPro” research project at the Fraunhofer Institute for Production Technology IPT in Aachen. The Aachen researchers have now published their findings on the development and implementation of a data structure that can fully describe digital…
International research project confirms possibility for attacks on touchscreens. Usually, an action by the user, such as accidentally clicking on a link, is required to install malware on a smartphone. However, scientists at TU Darmstadt and Zhejiang University have now succeeded in remotely controlling smartphones by imitating touches on the touchscreen. In an international research project, scientists at the System Security Lab of TU Darmstadt and Zhejiang University in Hangzhou managed, for the first time, to perform targeted attacks on…
Novel method simulates tens of thousands of bubbles in foamy flows. Bubbles aren’t just for bath time. Bubbles, specifically bubbles in foamy flows, are critical for many industrial processes, including the production of food and cosmetics and drug development and delivery. But the behavior of these foamy flows is notoriously difficult to compute because of the sheer number of bubbles involved. Previous attempts to simulate foamy flows have relied on the time-consuming and computationally expensive process of tracking the bubbles…
Roads are chronically congested and vehicles queue endlessly at junctions. Rush hour is especially bad for long traffic jams. At the Fraunhofer Institute for Optronics, System Technologies and Image Exploitation IOSB, researchers in the institute branch for industrial automation INA in Lemgo are using artificial intelligence for smart traffic light control as part of the “KI4LSA” and “KI4PED” projects. In the future, self-learning algorithms combined with new sensors should ensure better traffic flow and shorter waiting times, while providing improved…
Supported by an NSF Early CAREER Award, John Harter’s research could have far-reaching consequences for quantum technology development. John Harter, an assistant professor of materials at UC Santa Barbara, has received an Early CAREER award from the National Science Foundation (NSF), the highest honor given by the foundation to junior faculty. He will receive more than $715,000 over five years in support of his cutting-edge research in quantum materials science and educational activities. “Professor John Harter is pursuing leading-edge research…
New method from Clemson University researcher, enabled by Frontera supercomputer, helps explain role of phonons in copper-based superconductivity. Researchers have known about high-temperature superconducting copper-based materials, or cuprates, since the 1980s. Below a certain temperature (approximately -130 degree Celsius), electrical resistance vanishes from these materials and magnetic flux fields are expelled. However, the basis for that superconductivity continues to be debated and explored. “It has been widely accepted that traditional superconductors result from electrons interacting with phonons, where the phonons…
What size will a quantum computer need to be to break Bitcoin encryption or simulate molecules? Quantum computers are expected to be disruptive and potentially impact many industry sectors. So researchers in the United Kingdom and the Netherlands decided to explore two very different quantum problems: breaking the encryption of Bitcoin (a digital currency) and simulating the molecule responsible for biological nitrogen fixation. In AVS Quantum Science, from AIP Publishing, the researchers describe a tool they created to determine how…
Project consortium presents powerful IT infrastructure for innovative dual-arm AUV. Autonomous underwater vehicles (AUVs), operated and controlled by artificial intelligence (AI) methods, inspect, maintain, and repair offshore installations underwater. A consortium led by the German Research Center for Artificial Intelligence (DFKI) developed a holistic solution in the Mare-IT project to make this vision a reality: an innovative, two-armed AUV for complex inspection and maintenance tasks, embedded in a powerful IT infrastructure that enables both intuitive control and monitoring of the…
TU Graz develops simulation tools for transponder occupancy. The simulation tool developed at the Institute of Microwave and Photonic Engineering shows the site-specific transponder occupancy caused by radar interrogations in Austrian or pan-European airspace. Transponders are part of the mandatory equipment of civil aircraft: they are electronic devices that respond to radar interrogations and thus help air traffic control and air collision avoidance systems of other aircraft in the sky to determine the exact position of the aircraft. The time…
TACC supercomputers help scientists probe vortices and turbulence. The subject of vortices might seem esoteric. But their impact does make headlines, as seen recently in an outbreak of tornadoes, swirling vortices that killed at least 80 people across eight U.S. states in December 2021. Scientists today still don’t fully understand the dynamics of vortices, chaotic but coherent patterns common in nature that are also exemplified by hurricanes, eddies in a stream of air or water, aerodynamic drag, fuel combustion, and…
Steep sections on slippery ground, high steps, scree and forest trails full of roots: the path up the 1,098-metre-high Mount Etzel at the southern end of Lake Zurich is peppered with numerous obstacles. But ANYmal, the quadrupedal robot from the Robotic Systems Lab at ETH Zurich, overcomes the 120 vertical metres effortlessly in a 31-minute hike. That’s 4 minutes faster than the estimated duration for human hikers – and with no falls or missteps. This is made possible by a new…
