Non-convex, non-local functionals converging to the total variation

We present new results concerning the approximation of the total variation, integral(Omega)vertical bar del u vertical bar, of a function u by non-local, non-convex functionals of the form Lambda delta(u) = integral(Omega)integral(Omega)delta phi(vertical ...

Continuous Monitoring of Bed-Load Transport in a Laboratory Flume Using an Impact Sensor.

Christophe Ancey, Blaise Etienne Marceau Dhont, Gauthier Paul Daniel Marie Rousseau

Bed-load transport rate in gravel-bed rivers shows large non-Gaussian fluctuations, even under steady flow conditions. The development of high-resolution measurement techniques during the last two decades creates research opportunities to study the intermi ...

The seismic stability and ductility of steel columns interacting with concrete footings

Dimitrios Lignos, Hiroyuki Inamasu

First-story columns in steel moment resisting frames are subjected to various forms of geometric instabilities during earthquakes. These instabilities have the potential to seriously compromise structural performance, and expedite structural collapse. In t ...

Hybrid Neural Networks for Learning the Trend in Time Series

Karl Aberer, Tao Lin, Tian Guo

The trend of time series characterizes the intermediate upward and downward behaviour of time series. Learning and forecasting the trend in time series data play an important role in many real applications, ranging from resource allocation in data centers, ...

On the Richter-Thomassen Conjecture about Pairwise Intersecting Closed Curves

János Pach, Gábor Tardos

A long-standing conjecture of Richter and Thomassen states that the total number of intersection points between any n simple closed Jordan curves in the plane, so that any pair of them intersect and no three curves pass through the same point, is at least ...

Inhomogeneous minima of mixed signature lattices

Eva Bayer Fluckiger, Martino Borello, Peter Simon Jossen

We establish an explicit upper bound for the Euclidean minimum of a number field which depends, in a precise manner, only on its discriminant and the number of real and complex embeddings. Such bounds were shown to exist by Davenport and Swinnerton-Dyer ([ ...

Development of the methodology for the evaluation of a hydro-pumped storage power plant: Swiss case study

Edgard Gnansounou, Nikolaos Iliadis

During the last two decades, an evolving market structure is recognised starting from the spot market and its derivatives, resulting to several other markets such as the Intraday Market (IM), the Balancing Market (BM) and the Reserve Capacity Market (RCM). ...

Group diffusion LMS

Ali H. Sayed, Jie Chen

Considering groups of variables, rather than variables individually, can be beneficial for estimation accuracy if structural relationships between variables exist (e.g., spatial, hierarchical or related to the physics of the problem). Group-sparsity induci ...

Probabilistic simulations of TBM Tunnelling in highly fractured and faulted rocks

Federica Sandrone, Jian Zhao, Jean-Paul Dudt, Erika Paltrinieri

Despite the potential excellent performance of TBMs in favourable ground conditions, the presence of fault zones or heavily jointed rocks represent important geological hazards encountered during tunnel excavation. The effects of these challenging environm ...
