Siemens received an order from the Paris public transport operator RATP (Régie Autonome des Transports Parisiens) to equip the 27 stations of Paris Metro Line 4 with signaling and operations control systems. Fully automatic operation can increase the capacity of this line by up to 20 percent because trains will be able to run at shorter headways.
"Siemens has equipped about 300 route km worldwide with signaling technology for fully automatic operation, making it the market leader in this field. Automatic operation will enable Line 4 to offer a service interval of 85 seconds.
At the same time, the automatic control will allow to reduce energy consumption by up to 15 percent," says Jochen Eickholt, CEO of Siemens Mobility. The order volume totals around 70 million euros. Work on the line is scheduled for completion in 2022.
To upgrade the twelve kilometers of Line 4, Siemens will supply the Trainguard MT automatic train control system that uses communications-based technology to achieve fully automatic, driverless operation. All train movements will be supervised via the operation control center, which will also be supplied by Siemens.
Special doors at the platforms will ensure additional safety at all 27 metro stations. With around 700,000 passengers a day, Line 4 of the Paris Metro is one of the most frequented sections of the whole Paris mass transit network.
It is also the most important north-south metro link in the city, connecting the stations of Porte de Clignancourt in the north of the city and future station Bagneux in the south. On its way through France's capital it stops at three major long-distance railway stations and is also the only line with transfer terminals to all 16 other mass transit lines.
Apart from Line 4, Siemens has also equipped Metro Lines 14 and 1 for driverless operation. Metro Line 1 is the oldest and most heavily frequented underground line in Paris. It links the east and west of the city along 17 kilometers of track. Siemens has likewise recently supplied important signaling components and systems for Lines 3, 5 and 9.

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
