We consider the one-dimensional nonlinear Schrödinger equation with a nonlinearity of degree . We exhibit measures on the space of initial data for which we describe the non t…
Qualitative properties of Hénon type equations with exponential nonlinearity
Zongming Guo, Xia Huang, Dong Ye +1
We are interested in the qualitative properties of solutions of the Hénon type equations with exponential nonlinearity. First, we classify the stable at infinity solutions of $Δu +…
Knowledge Graphs Evolution and Preservation -- A Technical Report from ISWS 2019
Nacira Abbas, Kholoud Alghamdi, Mortaza Alinam +71
One of the grand challenges discussed during the Dagstuhl Seminar "Knowledge Graphs: New Directions for Knowledge Representation on the Semantic Web" and described in its report is…
Evolving the Behavior of Machines: From Micro to Macroevolution
Jean-Baptiste Mouret
Evolution gave rise to creatures that are arguably more sophisticated than the greatest human-designed systems. This feat has inspired computer scientists since the advent of compu…
Revisit 1D Total Variation restoration problem with new real-time algorithms for signal and hyper-parameter estimations
Zhanhao Liu, Marion Perrodin, Thomas Chambrion +1
1D Total Variation (TV) denoising, considering the data fidelity and the Total Variation (TV) regularization, proposes a good restored signal preserving shape edges. The main issue…
A fast semi-discrete optimal transport algorithm for a unique reconstruction of the early Universe
Bruno Lévy, Roya Mohayaee, Sebastian von Hausegger
We leverage powerful mathematical tools stemming from optimal transport theory and transform them into an efficient algorithm to reconstruct the fluctuations of the primordial dens…
All-optical helicity-independent switching state diagram in GdFeCo alloys
Jiaqi Wei, Boyu Zhang, Michel Hehn +5
Ultra-fast magnetization switching induced by a single femtosecond laser pulse, under no applied magnetic field has attracted a lot of attention during the last 10 years because of…
Fuzzy model identification based on mixture distribution analysis for bearings remaining useful life estimation using small training data set
Fei Huang, Alexandre Sava, Kondo H. Adjallah +1
The research work presented in this paper proposes a data-driven modeling method for bearings remaining useful life estimation based on Takagi-Sugeno (T-S) fuzzy inference system (…
Bearings degradation monitoring indicators based on discarded projected space information and piecewise linear representation
Fei Huang, Alexandre Sava, Kondo H. Adjallah +1
Condition-based maintenance of rotating mechanics requests efficient bearings degradation monitoring. The accuracy of bearings degradation measure depends largely on degradation in…
Studying Node Cooperation in Reputation Based Packet Forwarding within Mobile Ad hoc Networks
Sara Berri, Vineeth Varma, Samson Lasaulce +2
In the paradigm of mobile Ad hoc networks (MANET), forwarding packets originating from other nodes requires cooperation among nodes. However, as each node may not want to waste its…
Thermal properties study of silicon nanostructures by photoacoustic techniques
K. Dubyk, T. Nychyporuk, V. Lysenko +5
The photoacoustic method with piezoelectric detection for the simultaneous evaluation of the thermophysical properties is proposed. The approach is based on the settling of an addi…
A regularity result for the bound states of -body Schrödinger operators: Blow-ups and Lie manifolds
Bernd Ammann, Jérémy Mougel, Victor Nistor
We prove regularity estimates in weighted Sobolev spaces for the -eigenfunctions of Schrödinger type operators whose potentials have inverse square singularities and uniform r…
Symmetry Breaking Differential Operators for Tensor Products of Spinorial Representations
Jean-Louis Clerc, Khalid Koufany
Let be a Clifford module for the complexified Clifford algebra , its dual, and be the corresponding representations o…
Ultrabroadband beam splitting in a dissipative system of three waveguides
Rim Alrifai, Virginie Coda, Jonathan Peltier +2
We show that a system of three parallel waveguides, among which the central one is dissipative, leads to an ultrabroadband power splitting associated with an overall 50% power loss…
Construction of set-valued dual processes on manifolds
Marc Arnaudon, Koléhè Coulibaly-Pasquier, Laurent Miclo
The purpose of this paper is to construct a Brownian motion taking values in a Riemannian manifold , together with a compact valued process $D:= (D_t)_{t\…
Nanocontact vortex oscillators based on CoMnGe pseudo-spin valves
Jérémy Létang, Claudia de Melo, Charles Guillemard +9
We present an experimental study of vortex dynamics in magnetic nanocontacts based on pseudo spin valves comprising the CoMnGe Heusler compound. The films were grown by molecul…
A new instrument for kinetics and branching ratio studies of gas phase collisional processes at very low temperatures
Olivier Durif, Michael Capron, Joey P. Messinger +13
A new instrument dedicated to the kinetic study of low-temperature gas phase neutral-neutral reactions, including clustering processes, is presented. It combines a supersonic flow…
Time-Resolved XUV absorption spectroscopy and magnetic circular dichroism at the Ni -edges
Marcel Hennes, Benedikt Rösner, Valentin Chardonnet +21
Ultrashort optical pulses can trigger a variety of non-equilibrium processes in magnetic thin films affecting electrons and spins on femtosecond timescales. In order to probe the c…
Asymptotic limit for the Stokes and Navier-Stokes problems in a planar domain with a vanishing hole
Alexandre Munnier
We show that the eigenvalues of the Stokes operator in a domain with a small hole converge to the eigenvalues of the Stokes operator in the whole domain, when the diameter of the h…
When to stop value iteration: stability and near-optimality versus computation
Mathieu Granzotto, Romain Postoyan, Dragan Nešić +2
Value iteration (VI) is a ubiquitous algorithm for optimal control, planning, and reinforcement learning schemes. Under the right assumptions, VI is a vital tool to generate inputs…
