Bad weather is bad news for any ship. High-speed craft, able to skim open seas at 35 knots or more, are particularly vulnerable in strong winds. But captains may soon base their sail decisions on real-time information, generated by sophisticated new on-board equipment.
Some 300 high-speed vessels today criss-cross busy European sea routes. Though popular with passengers, they are more prone to cancellation than traditional ships when the weather turns nasty. According to Marielle Labrosse of French engineering company Mettle and coordinator of the IST project Wings-for-Ships, "Unwelcome weather adversely affects around 8 per cent of crossings by these ships. That is when those responsible for making the decision to go or not must think very carefully."
Fast vessels are most efficient and profitable travelling at top speed in calm waters. So if bad weather leads to their cancellation or forces them to slow down or return to port, they become a liability for their owners.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
