Dynamics of cavitation bubbles near granular boundaries

Mohamed Farhat, Davide Bernardo Preso, Armand Baptiste Sieber

We study the dynamics of a cavitation bubble near beds of sand of different grain sizes. We use high-speed imaging to observe the motion of the bubble and the sand for different values of the stand-off parameter gamma (dimensionless bubble-boundary distanc ...

High-speed imaging of snow saltation: wind tunnel experiments using natural snow

Michael Lehning, Daniela Brito Melo, Benjamin Andreas Walter

Drifting snow is a multi-scale process. It is composed of particles rolling and sliding along the surface, particles in saltation following short ballistic trajectories in the first 10 cm above the surface and particles in suspension at higher regions of t ...

Efficient ensemble summaries are inversely related to visual crowding

Michael Herzog, David Pascucci, Yury Markov, Natalia Tiurina

Visual crowding is the inability to perceive properly peripheral stimuli within clutter. Previous work has shown that crowding is affected by perceptual grouping: when the flankers do not group with the target, crowding decreases, leading to uncrowding. Ty ...

Effects of episodic rainfall on a subterranean estuary

David Andrew Barry, Clare Robinson

Numerical simulations were conducted to examine the effect of episodic rainfall on nearshore groundwater dynamics in a tidally influenced unconfined coastal aquifer, with a focus on both long- (yearly) and short-term (daily) behaviour of submarine groundwa ...

Capacity and Data Complexity in Multidimensional Linear Attack

Serge Vaudenay, Jialin Huang

Multidimensional linear attacks are one of the most powerful variants of linear cryptanalytic techniques now. However, there is no knowledge on the key-dependent capacity and data complexity so far. Their values were assumed to be close to the average valu ...

Snow particle characteristics in the saltation layer

Michael Lehning, Benjamin Andreas Walter

Shadowgraphy was employed to study snow saltation in boundary-layer wind tunnel experiments with fresh, naturally deposited snow. The shadowgraphy method allowed for a temporally and spatially high-resolution investigation of snow particle characteristics ...

Memory of past random wave conditions in submarine groundwater discharge

David Andrew Barry, Clare Robinson

Submarine groundwater discharge (SGD) is an integral part of the hydrological cycle and represents an important aspect of land-ocean interactions. We used a numerical model to simulate flow and salt transport in a nearshore groundwater aquifer under varyin ...

Stochastic simulation of intermittent DSD fields in time

Alexis Berne, Marc Schleiss, Joël Jaffrain

A method for the stochastic simulation of (rain)drop size distributions (DSDs) in space and time using geostatistics is presented. At each pixel, the raindrop size distribution is described by a Gamma distribution with two or three stochastic parameters. T ...
