Comparison of PI controllers designed for the delay model of TCP/AQM networks
(2013-06)"One of the major problems of communication networks is congestion. In order to address this problem in TCP/IP networks, Active Queue Management (AQM) scheme is recommended. AQM aims to minimize the congestion by regulating ... -
Complete stability region of PD controllers for TCP/AQM networks
(2016)"This paper addresses the stabilization problem of delay models of Transmission Control Protocol/Active Queue Management (TCP/AQM) by using a Proportional- Derivative (PD) controller as AQM strategy. The complete set of ... -
Computing non-fragile PI controllers for delay models of TCP/AQM networks
(2009)"This article focuses on the stabilisation problem of fluid-flow delay models of transmission control protocol/active queue management (TCP/AQM) networks by using a proportional-integral (PI) controller as AQM strategy. ... -
Computing the Conway polynomial of several closures of oriented 3-braids
(2012-03)"This paper deals with polynomial invariants of a class of oriented 3-string tangles and the knots (or links) obtained by applying six different closures. In Cabrera-Ibarra (2004) [1], expressions were given to compute the ... -
Conditions for synchronization and chaos in networks of β-cells
(2009)"The insulin producing and releasing pancreatic β-cells play a key role in glucose homeostasis. The proper function of these cells is characterized by a spiking-bursting activity in their membrane potential. It is known ... -
Conditions to Flatten the Curvature Tensor Associated with a Symmetric Affine Connection
(Hindawi, 2022)"In this study, we present a problem that consists in flattening the curvature associated with an affine connection on R2 . This problem involves distributions and symmetric affine connections defined on a differential ... -
Constant-length random substitutions and gibbs measures
(2018)"This work is devoted to the study of processes generated by random substitutions over a finite alphabet. We prove, under mild conditions on the substitutions rule, the existence of a unique process which remains invariant ... -

Efficiency of quarantine and self-protection processes in epidemic spreading control on scale-free networks
(2018)"One of the most effective mechanisms to contain the spread of an infectious disease through a population is the implementation of quarantine policies. However, its efficiency is affected by different aspects, for example, ... -
Electronic implementation of a dynamical network with nearly identical hybrid nodes via unstable dissipative systems
