Long-term Monitoring of the Sierra Nevada Snowpack Using Wireless Sensor Networks
Historically, the study of mountain hydrology and the water cycle has been largely observational, with meteorological forcing and hydrological variables extrapolated from a few infrequent manual measurements. Recent developments in Internet of Things (IoT) technology are revolutionizing the field of mountain hydrology. Low-power wireless sensor net...
Enriched finite elements and local rescaling for vibrations of axially inhomogeneous Timoshenko beams
This work presents a new enriched finite element method dedicated to the vibrations of axially inhomogeneous Timo-shenko beams. This method relies on the "half-hat" partition of unity and on an enrichment by solutions of the Timo-shenko system corresponding to simple beams with a homogeneous or an exponentially-varying geometry. Moreover, the effic...

On the convergence of augmented Lagrangian method for optimal transport between nonnegative densities
The dynamical formulation of the optimal transport problem, introduced by J. D. Benamou and Y. Brenier, corresponds to the time-space search of a density and a momentum minimizing a transport energy between two densities. In order to solve this problem, an algorithm has been proposed to estimate a saddle point of a Lagrangian. We will study the con...
Critical length: an alternative approach
Two numerical methods to evaluate stop-loss premiums
Two numerical methods are proposed to numerically evaluate the survival function of a compound distribution and the stop-loss premiums associated with a non-proportional global reinsurance treaty. The first method relies on a representation of the probability density function in terms of Laguerre polynomials and the gamma density, the second is a n...
Minimizing distortions with sectored GEM electrodes
...
Electrode sectorization is an important design principle for large area GEM based detectors. It reduces the energy of discharges and permits to disconnect defective or shorted sectors, but induces a local signal distortion and a potential efficiency loss. We implemented and evaluated a new design approach for the insulating gaps between electrode s...
On a toy network of neurons interacting through their dendrites
Consider a large number $n$ of neurons, each being connected to approximately $N$ other ones, chosen at random. When a neuron spikes, which occurs randomly at some rate depending on its electric potential, its potential is set to a minimum value $v_{min}$, and this initiates, after a small delay, two fronts on the (linear) dendrites of all the neur...
Elimination-based certificates for triangular equivalence and rank profiles
In this paper, we give novel certificates for triangular equivalence and rank profiles. These certificates enable somebody to verify the row or column rank profiles or the whole rank profile matrix faster than recomputing them, with a negligible overall overhead. We first provide quadratic time and space non-interactive certificates saving the loga...
