Since the early 1960s, near-surface seismic refraction tomography (SRT) has been extensively used as a non-invasive and cost-effective geophysical method to characterize complex geological structures for landslide investigation. This technique is able slope material, sliding surface's geometry, mass movement, physical properties of media, water saturation effects on slope. Therefore, this becom...

Using recordings of swell from pitch-and-roll buoys, we have reproduced the classic observations of long-range surface wave propagation originally made by Munk et al. (1963) using a triangular array of bottom pressure measurements. In the modern data, the direction of the incoming swell fluctuates by about ±10 ◦ on a time scale of one hour. But if the incoming direction is averaged over the dur...

This paper presents a rapid method to render dynamic water surfaces with penetrating obstacles in real-time. Taking the surface boundary into account, our method allows the rendering of single reflections and single refractions of objects even intersecting the water surface, including a physically approximative perspective refraction mapping. Thereby, water surfaces are represented as 2.5D heig...

Current techniques of water wave visualisation such as shadowgraphy and stereophotography are widely used but are deficient in many aspects. Refraction based visualisation observes the bending of light as it traverses across a water wave -air interface. This work describes the continued development of techniques to measure the surface height of a liquid free surface. The method utilizes refract...

On NaCl(100)/Cu(111) an interface state band is observed that descends from the surface-state band of the clean copper surface. This band exhibits a Moiré-pattern-induced one-dimensional band gap, which is accompanied by strong standing-wave patterns, as revealed in low-temperature scanning tunneling microscopy images. At NaCl island step edges, one can directly see the refraction of these stan...

In interactive applications such as games, particle-based liquids are often used for simulation. Such liquids are rendered with only a single refraction at the front-facing surface, which damages photorealism because it cannot express the thickness of liquid. In this paper, we propose an approach to render particle-based liquid with twice refraction at frontand back-facing surfaces in real time...

Geophysical surveys are a noninvasive reliable tool to improve geological models without requiring extensive in situ borehole campaigns. The usage of seismic refraction tomography (SRT), electrical resistivity (ERT) and data for calibrating is very appropriate define landslide body geometries; however, it still only used occasionally. We present here the case Spanish Pyrenees slow-moving landsl...
