Major advances in smartphones and tablets in terms of their built-in sensors (esp. cameras),
available computational power and on-board memory are transforming the role of such …

Power laws fit to rockfall frequency-magnitude distributions are commonly used to
summarize rockfall inventories, but uncertainty remains regarding which variables control …

Rockfall inventories are essential to quantify a rockfall activity and characterize the hazard.
Terrestrial laser scanning and advancements in processing algorithms have resulted in …

We present a monitoring technique tailored to analysing change from near-continuously
collected, high-resolution 3-D data. Our aim is to fully characterise geomorphological …

Obstacle detection plays an important role in train automatic operation. To overcome the low
accuracy and poor real-time performance of traditional detection methods, and better detect …

Rockfall is a common hazard along US Interstate Highway 70 in Glenwood Canyon,
Colorado. While natural rock slopes source a substantial number of rockfalls, there remains …

High-resolution remote monitoring of slopes using terrestrial LiDAR and photogrammetry is
a valuable tool for the management of civil and mining geotechnical asset hazards, but …

In the European Alps almost half the glacier volume disappeared over the past 150 years.
The loss is reflected in glacier retreat and ice surface lowering even at high altitude. In steep …

Excellent active obstacle detection capability is critical to operate fully automatic trains safely
and reliably. There are some problems exist in the traditional sensor-based obstacle …

Defining the relationship between volume and return period is critical when estimating the
risk of rockfalls and/or rock avalanche, especially during continued global warming at high …
