Gait characterizations in Parkinson's disease
(Universidad Nacional de ColombiaBogotá - Medicina - Maestría en Ingeniería BiomédicaFacultad de MedicinaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022)
La enfermedad de Parkinson (EP) es una enfermedad neurodegenerativa que afecta el sistema de control motor encargado de los movimientos voluntarios del cuerpo humano y las funciones cognitivas. EP es la segunda enfermedad ...
Mean motion resonances among the small satellites of Saturn and Pluto
(Universidade Estadual Paulista (Unesp), 2019-10-30)
This work is organized into three parts. In Part I, we present a quick review of Saturn’s satellites Prometheus and Pandora lags problem. We analyzed the lags ratio Q = ∆λpro ∆λpan through the conservation of the angular ...
Dinámica de un biorreactor con modelo de crecimiento de bacterias lineal por tramos
(2011)
El presente trabajo trata sobre la dinámica de un bioreactor UASB (Reactor Anaeróbico de Flujo Ascendente y Manto de Lodos), ubicado en los Laboratorios de Procesos Productivos de la Universidad Nacional de Colombia Sede ...
Design of reactor-separator-recycle systems based on the optimization of estimations of the domain of attraction
(American Chemical Society, 2011-06)
In this paper, an optimization-based methodology is applied to the design of a reactor-separator-recycle system based on a measure of the extension of the domain of attraction of the operating equilibrium. The approach ...
Coordination and control of fixed-wing aerial robots
(Universidade Federal de Minas GeraisUFMG, 2019-02-18)
Multi-agent systems have received much attention in the last years, since they are able to perform tasks better, faster or even those that are unfeasible for single agents. This work presents a MILP (mixed integer linear ...
Discrete-time output trajectory tracking for induction motor using a neural observer
(2008)
This paper presents the design of an adaptive controller based on the block control technique, and a new neural observer for a class of MIMO discrete-time nonlinear systems. The observer is based on a recurrent high-order ...
Concentrating standing waves for the fractional nonlinear Schrodinger equation
(Elsevier, 2014-01-15)
We consider the semilinear equation
epsilon(2s)(-Delta)(s)u + V(x)u - u(p) = 0, u > 0, u is an element of H-2s(R-N)
where 0 < s < 1, 1 < p < N+2s/N-2s, V (x) is a sufficiently smooth potential with inf(R) V(x) > ...
Stabilization of MT-HVDC grids via passivity-based control and convex optimization
(Cartagena de Indias, 2021-04-30)
This paper presents a model for stabilizing multi-terminal high voltage direct-current (MT-HVDC) networks with constant power terminals (CPTs) interfaced with power electronic converters. A hierarchical structure of ...
