A combined neural network/gradient-based approach for the identification of constitutive model parameters using self-boring pressuremeter tests

This paper presents a numerical procedure of material parameter identification for the coupled hydromechanical boundary value problem (BVP) of the self-boring pressuremeter test (SBPT) in clay. First, the neural network (NN) technique is applied to obtain ...

Mathematical modeling of the re-epithelialization of a 3 dimensional (3d) human skin equivalent

Raphaelle Luisier

Re-epithelialization is the dominant mode of healing in partial thickness wounds. In order to develop better strategies to monitor such wound healing, 3D HSE models and mathematical models have long been utilized to improve our understanding of epidermis f ...

Stress, individual differences, and norepinephrine in reinforcement learning-based prediction of mouse behavior in conditioning and spatial learning

Maria del Carmen Sandi Perez, Gediminas Luksys

Acute stress regulates different aspects of behavioral learning through the action of stress hormones and neuromodulators. Stress effects depend on stressor's type, intensity, timing, and the learning paradigm. In addition, genetic background of animals mi ...

Improving the boneh-franklin traitor tracing scheme

Arjen Lenstra, Alexandre Karlov, Pascal Junod

Traitor tracing schemes are cryptographically secure broadcast methods that allow identification of conspirators: if a pirate key is generated by k traitors out of a static set of l legitimate users, then all traitors can be identified given the pirate key ...

Estimating interdependences in networks of weakly coupled deterministic systems

Oscar De Feo, Cristian Carmeli

The extraction of information from measured data about the interactions taking place in a network of systems is a key topic in modern applied sciences. This topic has been traditionally addressed considering bivariate time series, providing methods that ar ...

Thermo-mechanical response of UHPFRC at early age — Experimental study and numerical simulation

Eugen Brühwiler, Emmanuel Denarié, Hamid Sadouki, Aicha Kamen

The thermal effects on the Ultra High Performance Fiber Reinforced Concrete (UHPFRC) behavior are still not completely known. Under high temperatures, the processes that interact at early age are thermo-activated. All the experimental results obtained with ...

Hierarchy of models for meandering rivers and related morphodynamic processes

Paolo Perona

We review the importance of the physical mechanisms involved in river meandering by comparing some existing linear models and extensions thereof. Such models are hierarchically derived from a common and general mathematical framework and then analyzed with ...

Modelling the E-J relation of high-Tc superconductors in an arbitrary current range

Francesco Grilli, Joseph Duron, Bertrand Dutoit

For describing the E-J relation of high-Tc superconductors (HTS) in power applications, where the applied current I is generally limited by Ic, the critical state model, a piecewise linear generalization, or a simple power-law of the type E=Ec(J/Jc)^n are ...
