Background: Ensuring adequate depth of anesthesia during surgery is essential for anesthesiologists to prevent the occurrence of unwanted alertness during surgery or failure to return to consciousness. Since the purpose of using anesthetics is to affect the central nervous system, brain signal processing such as electroencephalography (EEG) can be used to predict different levels of anesthesia....

The double porosity model allows to compute the pressure at a macroscopic scale in a fractured porous media, but requires the computation of some exchange coe cient characterizing the passage of the uid from and to the porous media (the matrix) and the fractures. This coe cient may be numerically computed by some Monte Carlo method, by evaluating the time a Brownian particle spend in the matrix...

This work is devoted to the study of a family of almost periodic one-dimensional Schrr odinger equations. We deene a monodromy matrix for this family. We study the asymptotic behavior of this matrix in the adiabatic case. Therefore, we develop a complex WKB method for adiabatic perturbations of periodic Schrr odinger equations. At last, the study of the monodromy matrix enables us to get some s...

We consider the H∞ almost output synchronization and regulated output synchronization problem for heterogeneous directed networks with external disturbances where agents are introspective (i.e. agents have access to a part of their own state). A decentralized protocol is designed for each agent, without exchanging internal controller states with neighboring agents, to achieve output synchroniza...
