Neuropsychological assessment of patients with relapsing remitting multiple sclerosis prior to the use of immunomodulatory drugs Evaluación neuropsicológica en 129 pacientes chilenos con esclerosis múltiple recurrente remitente previo a inicio de fármacos
(2012)
Background: The detection of cognitive changes (CC) and psychiatric disorders in relapsing remitting multiple sclerosis (MS-RR) contributes to patient clinical monitoring. Aim: To assess the frequency and characteristics ...
Mathematical modelling of fluid transport and its regulation at multiple scales
(Elsevier, 2015-04)
Living matter equals water, to a first approximation, and water transport across barriers such as membranes and epithelia is vital. Water serves two competing functions. On the one hand, it is the fundamental solvent ...
Taxia e agregação não local em um sistema planta herbívoro
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2013-04-11)
The dispersal of herbivorous insects in large plantations must be modelled by
taking into account many behavioral aspects of the individual movement. The insect
ability to search for (and find) better plant quality are ...
Learning to Control pH Processes at Multiple Time Scales
(The Berkeley Electronic Press, 2007-12)
This article presents a solution to pH control based on model-free learning control (MFLC). The MFLC technique is proposed because the algorithm gives a general solution for acid-base systems, yet is simple enough for ...
Parametric resonances in a base-excited double pendulum
(SPRINGERDORDRECHT, 2012)
Two parametrically-induced phenomena are addressed in the context of a double pendulum subject to a vertical base excitation. First, the parametric resonances that cause the stable downward vertical equilibrium to bifurcate ...
Existence and Multiplicity of Periodic Solutions for Dynamic Equations with Delay and singular φ-laplacian of Relativistic Type
(arXiv.org, 2020-05)
We study the existence and multiplicity of periodic solutions for singular ϕ-laplacian equations with delay on time scales. We prove the existence of multiple solutions using topological methods based on the LeraySchauder ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part II-resonance secondary
(Springer, 2010-06-01)
In Part II of this work, we investigated the dynamics of the shape memory oscillator, in the particular case of the secondary resonances. We used the equation of motion developed in Part I (Piccirillo et al., Nonlinear ...
Analytical study of the nonlinear behavior of a shape memory oscillator: Part I-primary resonance and free response at low temperatures
(Springer, 2010-03-01)
In this work, the response of a single-degree-of-freedom shape memory oscillator subjected to the excitation harmonic has been investigated. Equation of motion is formulated assuming a polynomial constitutive model to ...
