Monitoring against another Pompeii

06.08.2008
A wimax-based connection to the internet will enable real-time monitoring of potentially dangerous active volcanoes.

For effective monitoring of volcanic activity, scientists want to know what is happening in real time, not the pattern of events last week. For many remote volcanoes, that has just not been possible. Now, a new system, intended to monitor activity around Mount Vesuvius in Italy and at volcanoes in Iceland, offers a major step forward in real-time communications.

In Iceland, scientists have been driving to their remote volcanic monitoring stations about once a week in order to download the data from the station hard disk and then returning to their laboratories to analyse it. The new monitoring system can deliver around 75 megabits of data remotely per second over a WiMAX wireless connection.

The WiMAX system offers a robust, high-quality connection. Transmitting rich data like this, it is very important not to lose any of it, suggests Enrico Argori, a leading researcher on the WEIRD project that developed the monitoring system. “WiMAX is the cheapest channel… to do this, and it is the channel that can deliver the best quality of service.”

The monitoring system does not swamp the airwaves with useless data. Only when significant activity occurs will the monitoring system communicate data. And critical transmissions can be protected from interference. Bandwidth can be reserved using a protocol called DIAMETER, that identifies data traffic and prioritises information from the volcanic monitoring centre to ensure communications are not blocked by lower-priority data traffic, such as messaging.

Though far from a new technology, the WEIRD research team has managed to extend WiMAX’s resilience and flexibility.

WEIRD agents on the job

The monitoring system includes a series of features that are important for the future integration of WiMAX with other wireless and telecommunications systems we use. The WEIRD team seamlessly integrated WiMAX with a range of other network technologies to enable high-quality, end-to-end communication, regardless of the route it takes.

WEIRD developed software that exploits the advantages of ‘next-generation networks’. NGNs layer information, decoupling the applications from the underlying transport stratum. Whatever the underlying network, the volcano monitoring signals will be relayed in full from end to end.

Not all applications are designed to run on next-generation networks. For these, the research team built a series of adaptors – known as WEIRD agents or WEIRD application programming interfaces – that allowed non-NGN applications to take advantage of the boosted quality of service and seamless mobility features of the wireless volcano-monitoring system.

WiMAX is being viewed more and more as a complementary, rather than competing, technology to existing wireless communication access channels, such as wifi and mobile telephony services. So, the successful seamless integration of WiMAX via ‘media-independent handover’ is an important step forward.

Pan, zoom… trouble

An important feature of WEIRD’s monitoring system is not that it is technically possible but that it can be practically applied by non-communications specialists.

Software was developed that hides the complexity of the configuration of end-to-end communication channels, whatever the different equipment or different versions of WiMAX used. It means that a member of the monitoring team can quickly and easily establish an end-to-end communication path without specialist training, allowing them to concentrate on what is vitally important at the time – their monitoring job.

Bi-directionality was also tested in this setting, meaning that the volcano monitors can pan or zoom onto a potential trouble spot with the remote cameras, as well as receive signals from them.

“The main part of our work is to make it easy for end-users [to benefit] from new technologies like WiMAX,” explains another member of the WEIRD research team, Giuseppe Martufi.

WEIRD received funding from the EU's Sixth Framework Programme for research.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
