Thousands of people around the world have died in train wrecks caused by natural disasters. In 2004, the tsunami in Southeast Asia derailed a Sri Lankan train, killing 1,700 people. But with modern advances, these tragedies can be avoided — and a Tel Aviv University researcher, working in collaboration with teams from seven countries, is leading the way.
Prof. Lev V. Eppelbaum of Tel Aviv University's Department of Geophysics & Planetary Sciences and his colleagues are collecting high-tech sensing data from satellites, airplanes, magnetic and soil sensors, and unmanned aircraft to devise a solution that will provide a reliable early-warning system for train operators.
It's all part of the European Project FP7 research, "Integrated System for Transport Infrastructures Surveillance and Monitoring by Electromagnetic Sensing," which includes participants from Israel, Italy, France, Sweden, Norway, Switzerland and Romania. The international team of researchers aims to connect emerging technologies so that train accidents caused by avalanches, earthquakes and even terrorists can be avoided.
"We are creating a new interpretation system — allowing us to integrate cutting-edge technologies from across Europe," he says, adding that the biggest challenge, right now, is eliminating background "noise" from the data being collected.
Climatic features and parameters such as soil types and physical geography can be very different from one region to another, which makes the work even more of a challenge. Some of Prof. Eppelbaum's recent research advances have been reported in the Zeitschrift für Geomorphologie, the Journal of Arid Environments and the Proceedings of the SAGEEP Conference (USA).
On the right Amtrak
The international team also hopes to examine the additional risk of terror attacks on trains. While all the other data collected by the research teams will be made public, this section will remain top secret.
Prof. Eppelbaum expects their methods will be adopted by the world's railway systems. As the cost of fuel for cars and planes rises, and environmentally-friendly train travel is more heavily promoted, experts predict that more Americans will be riding the rails to work and between cities. In 2008, about 30 million passengers rode on Amtrak trains, and train ridership figures have been steadily increasing.
At present, there is no monitoring system for either natural disasters or terror attacks on rail systems in America or anywhere else. Prof. Eppelbaum says he has his work cut out for him: putting together different geophysical measurements and formats of sensors, he is collecting very different kinds of data and trying to turn it into usable information.
"It's complicated math and physics," says Prof. Eppelbaum. "And yes, it includes lots of scribbling and equations on the chalkboard."

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
