A cooperative conjugate gradient method for linear systems permitting efficient multi-thread implementation
(Springer, 2018)
This paper revisits, in a multi-thread context, the so-called multi-parameter or block conjugate gradient (B-CG)methods, first proposed as sequential algorithms by O’Leary and Brezinski, for the solution of the linear ...
Cooperative concurrent asynchronous computation of the solution of symmetric linear systems
(Springer, 2017-07)
This paper extends the idea of Brezinski's hybrid acceleration procedure, for the solution of a system of linear equations with a symmetric coefficient matrix of dimension n, to a new context called cooperative computation, ...
Interval observers for SIR epidemic models subject to uncertain seasonality
(Springer Verlag, 2017)
Epidemic models describe the establishment and spread of infectious diseases. Among them, the SIR model is one of the simplest, involving exchanges between three compartments in the population, that represent respectively ...
Interval observer for SIR epidemic model subject to uncertain seasonality
(EMAp - Escola de Matemática Aplicada, 2016)
The issue of state estimation is considered for a SIR model with seasonal variations and uncertainties in the transmission rate. Assuming continuous measurement of the number of new infectives per unit time, a class of ...
