Vistas in numerical relativity [PDF]

, 2002
Upcoming gravitational wave-experiments promise a window for discovering new physics in astronomy. Detection sensitivity of the broadband laser interferometric detectors LIGO/VIRGO may be enhanced by matched filtering with accurate wave-form templates ...

Fundamental Limitations of Disturbance Attenuation in the Presence of Side Information [PDF]

, 2007
In this paper, we study fundamental limitations of disturbance attenuation of feedback systems, under the assumption that the controller has a finite horizon preview of the disturbance.

Lecture notes on the DiPerna-Lions theory in abstract measure spaces [PDF]

, 2016
These notes closely correspond to a series of lectures given by the first author in Toulouse, on the recent extension of the theory of ODE well-posedness to abstract spaces, jointly obtained by the two authors.

On the stochastic simulation by optimal control and bifurcation analysis of the computer virus model in Caputo-type

Alexandria Engineering Journal
This study investigates a fractional-order computer virus model using the Caputo derivative to capture memory effects in digital networks. The model classifies nodes into four compartments: susceptible (S), latent (L), actively infected (B), and ...

Reconstruction of a piecewise constant conductivity on a polygonal partition via shape optimization in EIT [PDF]

, 2017
In this paper, we develop a shape optimization-based algorithm for the electrical impedance tomography (EIT) problem of determining a piecewise constant conductivity on a polygonal partition from boundary measurements.

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.
