Mobile technologies, including the global system for mobile communication (GSM) and the ZigBee short-range wireless data connection technology could be used to monitor and detect bushfires, according to two research papers to be published in the International Journal of Computer Aided Engineering and Technology.
Dry, but often vegetated regions, of the world, such as the Australian outback and West Coast USA, repeatedly succumb to wildfires. These serious natural disaster can have devastating effects on the landscape, agriculture, and dwellings as well as causing significant loss of life, property, and the environment.
In order to prevent bushfires from occurring or minimise their impact, accurate and early detection is essential. There are numerous monitoring and alarm systems available, but they do have various shortcomings.
Now, Liu Liu, Rong Sun, Ying Sun and Said Al-Sarawi of The University of Adelaide, Australia, are developing a smart bushfire monitoring system that can provide an early warning message. Their system uses the short message service (SMS) carried by GSM telephones. Temperature and humidity sensors are connected to a microcontroller, which is interfaced with a GPS receiver to report the module position and a GSM module to communicate the sensory information. This system offers several benefits over earlier detection and alarm systems, not least that of which is that it can be adapted to different settings easily at no great expense.
In parallel work, Sun, Yuan and Al-Sarawi have also investigated the potential of ZigBee technology for smarting monitoring of bushfires. The same system of sensors and monitors are hooked up to a base station via wireless ZigBee modules that feed into a wireless LAN (local area network), thus providing the option to monitor a property or site remotely via the internet rather than receiving status alerts via SMS.
The team points out that the ZigBee approach could also be expanded by linking modules together using a GPRS network to provide much wider coverage. This would enhance the benefits of both mobile networks and the internet in collecting data from different sources in a similar way to distributed sensory network, but with a much simpler initial setup.

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...
