According to the "The Rail Journey 2020" study, long-distance European rail traffic will increase by about 20 percent by 2020, and passenger numbers will exceed 1.36 billion.
Ensuring that this amount of mobility will be available in future is one of the major challenges of our times. An efficient long-distance railway infrastructure forms the basis for environmentally compatible mobility without borders, as well as for the further economic development of regions and countries.
Against this background, Siemens will demonstrate how safe, interoperable European rail traffic "without borders" can actually be achieved in Gallery 2, B3 at the 11th UIC (Union internationale des chemins de fer) ERTMS World Conference in Istanbul, which is to be held on April 1–4, 2014.
ETCS increases line capacity and ensures continuous rail traffic throughout Europe.
Train protection systems ensure safe rail transportation of passengers and goods. There are currently 14 different train protection systems in use in Europe, which are mutually incompatible. The European Union Directive issued in 1996 to resolve this compatibility problem obligated European train and network operators to equip their trains and lines with the European Train Control System (ETCS). ETCS is a modular system with standardized functions and interfaces that are available in a number of application levels. With ETCS Level 1, the signal aspects are transmitted to the vehicles with the aid of beacons called eurobalises. Level 2, however, uses the mobile radio standard GSM-R to transmit this information from a route control center to the vehicle. With this technology, information is continuously exchanged, independently of fixed signals. This facilitates short intervals between trains and considerably increases the route capacity and safety at speeds up to 350 km/h. At the World Conference, an ETCS emulator "ETCS live" will demonstrate the results of optimized acceleration, driving and braking operations in respect of punctuality and energy efficiency. Visitors will be able see an ATO (Automatic Train Operation) system: The demonstration is based on genuine track data, and every action of a real train driver has to be duplicated to move the train along the realistic track. The ATO beats the energy consumption achieved by even experienced train drivers by five to ten percent. This means that ETCS in combination with this component can use small reserves in the timetables to reap substantial energy savings. The Automation Train Operation system takes over the driving the train on the route and stops it with precision at the platforms. With the aid of the stored route profile, the system calculates how strongly the train has to accelerate and to brake before curves in order to arrive punctually at the next station – and, in doing so, consume as little energy as possible.
The Driver Advisory System optimizes train control and reduces energy consumption
In response to increasing energy and operating costs and in order to reduce CO2 emissions, more and more railway operators are finding it necessary to demand energy-saving, low-wear driving skills from their drivers. As train drivers are often deployed flexibly, they are not always capable of finding the ideal speed profile on every route. The DAS (Driver Advisory System) can now give them suggestions for improving train control. The combination of route data, such as maximum permissible speeds and distance between stations, as well as timetable information enable an optimized speed profile to be calculated and is then recommended to the train driver visually in real-time. The aim is to have drivers follow the optimum speed profile on every route in order to save energy and reduce wear. Whereas DAS still allows the train driver to control the train himself, the ATO system takes over optimized driving of the train until the train stops at the next platform.
Predictive maintenance by means of Condition Monitoring
Rail transportation systems have to run smoothly without interrupting the flows of passengers and goods. Competent and innovative servicing is required to meet the ever increasing availability demands of these systems. In this connection, Siemens uses "Condition Monitoring" to plan maintenance activities efficiently and minimize disruptions to operations. The system data is collected by long-distance transmission and flows directly into everyday maintenance activities. This enables impending damage to be detected at an early stage. Diagnostic data describes the current condition of the systems, assesses trends and provides a catalog of measures to rectify defects.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.
A warming planet
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

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...
