Writing in Inderscience's Journal of Design Research, the team explains how the new technology, with further industrial development, could eventually make vast tracts of land around the globe safe once more.
Landmines were first used widely during World War II and continue to represent a significant threat to life and limb in areas afflicted by war. Originally, landmines were used to protect strategic areas such as borders, camps or important bridges and to restrict the movement of enemy forces. The use of landmines has spread to countless national conflicts and they are now commonly used by terrorist and other organisations against civilians and rivals. This has led to a major proliferation of landmines in many areas beyond conventional military conflict zones.
In the absence of records, the low cost of landmines and the vast areas that have been polluted with them due to aerial distribution, clearing landmines has become and increasingly frustrating and hazardous task.
A single landmine might cost $1, but once in the ground locating it and making it safe can cost up to $1000. According to P. van Genderen and A.G. Yarovoy in the Faculty of Electrical Engineering at Delft University of Technology, this cost is prohibitive in most areas affected by landmine use and so a cheaper solution is needed. The researchers also point out that a detection system that does not distinguish between landmines and other buried objects is not viable.
The researchers explain that innovative technologies such as multi-hyper spectral sensors, passive millimetre wave detectors, and charged particle detection could be effective, but are likely to be very costly and complicated to use. Inexpensive methods such as conventional metal detectors and probing of the ground by a human operator are prone to serious error with major repercussions for the operators.
They have now turned to ultra-wideband radar as having the potential to be much easier to operate than the sophisticated technology but be just as effective and crucially far less expensive. The team has now developed a prototype system that successfully detects model landmines in a test environment. The detection rate is always offset by the false alarm rate, the researchers explain. The real step forward can be made if this balance can be made more favourable. Further work and development is now needed to shift the balance between detection rate and false alarm rate.

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
