The heating should only switch on when necessary, or the house should only be ventilated during the time that it takes to do this, but no longer. The Energy in Building research group has developed a prototype of a piece of equipment capable of monitoring more environmental variables and sending information to the user or even to another device so that action can be taken accordingly.
High-speed recordings of Egyptian fruit bats in flight show that instead of using a primitive form of echolocation, these animals actually use a technique recently developed by humans for surveillance and navigation.
A new study shows terahertz data links are possible even without direct line-of-sight between transmitter and receiver, a promising finding for future ultra-high-capacity terahertz data networks.
Electrical and optical engineers in Australia have designed a novel platform that could tailor telecommunication and optical transmissions. They experimentally demonstrated their system using a new transmission wavelength with a higher bandwidth capacity than those currently used in wireless communication. Reported this week in APL Photonics, these experiments open up new horizons in communication and photonics technology.
The 'internet of things,' which make everything from your toaster to your front door accessible online, has driven an explosion in data traffic and taken up huge amounts of bandwidth. However, a new range of frequencies in the terahertz region of the spectrum may soon be available for use. A paper in this week's APL Photonics demonstrates the feasibility of using THz carrier waves for data transmission in diverse situations and environments.
Vanadium dioxide's unique properties make it perfect for outperforming silicon and giving rise to a new generation of low-power electronic devices. Under the Phase Change Switch project, which is being funded by the EU's Horizon 2020 research program and coordinated by EPFL researchers, engineers have shown how this compound can be used to create programmable radiofrequency electronic functions for aerospace communication systems. Other applications -- such as in neuromorphic computing and artificial intelligence -- are also on the cards.
For the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometerFor the first time, researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometers over a standard fiber optic telecommunications network and used to synchronize two radio telescopes. s over a standard fiber optic telecommunications network and used to synchronize two radio telescopes.
An international team of scientists prove, for the first time, the security of so-called device-independent quantum cryptography in a regime that is attainable with state-of-the-art quantum technology, thus paving the way to practical realization of such schemes in which users don not have to worry whether their devices can be trusted or not.
A team of scientists, led by Boy Lankhaar at Chalmers University of Technology, has solved an important puzzle in astrochemistry: how to measure magnetic fields in space using methanol, the simplest form of alcohol. Their results, published in the journal Nature Astronomy, give astronomers a new way of investigating how massive stars are born.
USTC Guo's team realized strong coupling between distant phonon modes, by introducing a third resonator as a phonon cavity mode.
