Statistical modelling of the snow depth distribution in open alpine terrain

The spatial distribution of alpine snow covers is characterised by large variability. Taking this variability into account is important for many tasks including hydrology, glaciology, ecology or natural hazards. Statistical modelling is frequently applied ...

High-resolution, lensless endoscope based on digital scanning through a multimode optical fiber

Demetri Psaltis, Christophe Moser, Salma Farahi

We propose and experimentally demonstrate an ultra-thin rigid endoscope (450 mu m diameter) based on a passive multimode optical fiber. We use digital phase conjugation to overcome the modal scrambling of the fiber to tightly focus and scan the laser light ...

DBToaster: Higher-order Delta Processing for Dynamic, Frequently Fresh Views

Christoph Koch, Amir Shaikhha, Milos Nikolic, Daniel Lupei, Andres Nötzli, Yanif Ahmad

Applications ranging from algorithmic trading to scientific data analysis require realtime analytics based on views over databases receiving thousands of updates each second. Such views have to be kept fresh at millisecond latencies. At the same time, thes ...

Studies of the spatial variability of alpine snowfall using an X-band polarimetric radar

Michael Lehning, Alexis Berne, Danny Eddy Scipion Castillo

A mobile polarimetric X-band radar (MXPol) was deployed in Davos, Switzerland in collaboration with SLF (WSL - Institute for Snow and Avalanche Research). MXPol was installed in the beginning of October 2009 and collected valuable and continuous informatio ...

An innovative method to build support structures with a pulsed laser in the selective laser melting process

Rémy Glardon, Jamasp Jhabvala, Eric Boillat, Cédric André

In selective laser melting machines, continuous laser are usually used to melt the powder. The support structures, which are inevitable when dealing with elaborated pieces, necessitate a complex design by CAD in order to be easily removed. This paper propo ...

Laser scanning images analysis for tunnel inspection

Federica Sandrone

Laser scanning is commonly used in railways for detecting problems related with the clearance profile which are quite common especially in old tunnels. By increasing the resolution of the scanner system it is possible to use the images for identifying prob ...
