Through a project supported by the European Space Agency, the UK-based company Wired Ocean Ltd can now provide enhanced Internet access for ships at sea at a much lower cost than was previously possible.
Although satellite links at sea are quite common, the speed of data transmission for most users is very low, from 600 bps to 64 kbps, with around 10 kbps being a typical speed. This, combined with usage costs of around € 20 per megabyte, has created an environment in which many ship owners cannot reliably access the Internet, or use it regularly.
The Wired Ocean approach uses a hybrid solution, combining Ku-band satellites for the downlink and narrow L-band satellites for the return channel. While at sea, the downlink (forward) channel offers a speed of 512 kbps and the uplink (return) channel speed is 9.6 kbps for Globalstar and up to 64 kbps for Inmarsat. This configuration promises to be more economical than purely narrowband satellite systems, with cost savings of as much as 70% over current systems.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
