Mobile authentication of copy detection patterns

EURASIP Journal on Information Security, 2023
In the recent years, the copy detection patterns (CDP) attracted a lot of attention as a link between the physical and digital worlds, which is of great interest for the internet of things and brand protection applications.

Mathematical and Experimental Model of Neuronal Oscillator Based on Memristor-Based Nonlinearity

Mathematics, 2023
This article presents a mathematical and experimental model of a neuronal oscillator with memristor-based nonlinearity. The mathematical model describes the dynamics of an electronic circuit implementing the FitzHugh–Nagumo neuron model.

Asymptotic Normality of Nonparametric Kernel Regression Estimation for Missing at Random Functional Spatial Data

Journal of Mathematics, 2023
This study investigates the estimation of the regression function using the kernel method in the presence of missing at random responses, assuming spatial dependence, and complete observation of the functional regressor.

Stochastic Perron for Stochastic Target Problems [PDF]

Journal of Optimization Theory and Applications, 2016
In this paper, we adapt stochastic Perron's method to analyze a stochastic target problem with unbounded controls in a jump diffusion set-up. With this method, we construct a viscosity sub-solution and super-solution to the associated Hamiltonian-Jacobi-Bellman (HJB) equations.

Comparison of three recent discrete stochastic inversion methods and influence of the prior choice

Comptes Rendus. Géoscience, 2022
Groundwater flow depends on subsurface heterogeneity, which often calls for categorical fields to represent different geological facies. The knowledge about subsurface is however limited and often provided indirectly by state variables, such as hydraulic

Machine learning through cryptographic glasses: combating adversarial attacks by key-based diversified aggregation

EURASIP Journal on Information Security, 2020
In recent years, classification techniques based on deep neural networks (DNN) were widely used in many fields such as computer vision, natural language processing, and self-driving cars. However, the vulnerability of the DNN-based classification systems
