Numerical Analysis & No Regrets. Special Issue Dedicated to the Memory of Francisco Javier Sayas (1968-2019)
(WALTER DE GRUYTER GMBH, 2022)
This is the preface of a special issue dedicated to the memory of Francisco Javier Sayas who passed away on April 2, 2019. The articles reflect Sayas' main research interests in the numerical analysis of partial differential ...
Nonlinear Dynamics of Internet Congestion Control: A Frequency-domain Approach
(Elsevier Science, 2014-04)
In this paper a fluid-flow model for TCP congestion avoidance combined with different AQM schemes is analyzed. The conditions for the appearance of Hopf bifurcations are stated analytically using frequency-domain techniques. ...
Finite-element time-domain analysis of 2-D photonic crystal resonant cavities

A Comparative Study of Time Domain Compressed Sensing Techniques for Optoacoustic Imaging
(Institute of Electrical and Electronics Engineers, 2022-04)
Speeding up data acquisition and reducing the complexity of the detection system are among the central goals for advancing optoacoustic imaging. In this way, new reconstruction algorithms using the compressed sensing (CS) ...
Junction-Generalized Riemann Problem for stiff hyperbolic balance laws in networks: An implicit solver and ADER schemes
(Elsevier, 2016)
In this paper we design a new implicit solver for the Junction-Generalized Riemann Problem (J-GRP),whichis based on a recently proposed implicit method for solving the Generalized Riemann Problem (GRP) for systems of ...
The effect of actuator and sensor placement on the active control of rotor unbalance
(2003-07-01)
This paper investigates both theoretically and experimentally the effect of the location and number of sensors and magnetic bearing actuators on both global and local vibration reduction along a rotor using a feedforward ...
Numerical analysis of a time domain elastoacoustic problem
(2019)
This paper deals with the numerical analysis of a system of second order in time partial differential equations modeling the vibrations of a coupled system that consists of an elastic solid in contact with an inviscid ...
Design of protection schemes based on symmetrical components in the time domain
(Universidad de los AndesMaestría en Ingeniería EléctricaFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2021)
Symmetrical components theory, presented by Fortescue in 1918, and its analysis of the time domain presented by Lyon in 1954, have been widely used for fault analysis and power system protection algorithms. In recent times, ...
