Estrategias de control óptimas en la propagación de enfermedades en poblaciones acopladas
(2011-08)
En varias investigaciones se ha estudiado la aplicación de diversas estrategias de control en la propagación de enfermedades en una población dada. Ahora bien, tarea difícil es encontrar la combinación de estrategias que ...
A new preconditions for solving linear systems with symmetric Z-matrices
(2012-05)
There are many preconditioners for linear systems, for example, P = I + Smax developed by Kotakemori in [9] and its extension P˜ developed by Arenas & Yong in [1]. These preconditioners were built to speed up the convergence ...
Análisis topológico de recombinación de lugar específico utilizando el polinomio bracket
(2014-05)
Knots and Links can occur in the axis of DNA molecules as result of diverse enzyme actions. For site-specific recombination events there is no way to observe details of the process, so molecular biologists resort to indirect ...
Aplicación del método local discontinuous galerkin a ecuaciones con derivadas fraccionarias
(2018-12-19)
We consider a time dependent model problem with the Riesz or the Riemann-Liouville
fractional differential operator of order 1 < α < 2. We obtain optimal rates of convergence
for the semi-discrete minimal dissipation ...
Un modelo matemático para evaluar el efecto de herbivoría de la polilla (Oidaematophorus espeletiae Hernández, Fuentes Fajardo & Mathews) sobre el frailejón (Espeletia grandiflora Humb. & Bonpl.)
(2019-05-15)
The Espeletia grandiflora Humb. & Bonpl. commonly known as frailejón is a plant of the Eastern Andes of Colombia, such that its function within the ecosystem is to regulate the production of water. In 2012, it was found ...
Comparison of elastic plate theories for micropolar materials
(2010-05)
The purpose of this thesis is to develop a comparison between two theories of micropolar plates with moderate thickness. A comparison between the proposed and Eringen models is shown in the thesis. We used a special technique ...
The elliptic anisotropic problem with Wentzell boundary conditions and variable exponents
(2019-12-10)
Let $\Omega\subseteq\mathbb{R\!}^N$ be a bounded Lipschitz domain, for $N\geq3$. We investigate the solvability and regularity of a class of quasi-linear elliptic equations involving the anisotropic $\overset{\rightarrow ...
A mathematical model for ZIKA virus and the effects of variable infectivity on the asymptomatic and symptomatic infected human
(2018)
El Zika es una enfermedad infecciosa desarrollada por el Virus del Zika (ZIKV
por sus siglas en ingles), la cual ha estado, alertando a las regiones tropicales y
subtropicales en los ultimos a~nos. La enfermedad es ...
Aplicación de métodos de optimización en la solución de un problema de la industria editorial
(2010-05)
En la industria editorial, se deben crear los negativos de los documentos y las planchas donde se van a colocar dichos negativos para que luego sean enviadas a imprimir. Analizando los costos de imprimir documentos se notó ...
Vibration of cylinders of fractal structures
(2016-06)
The objective of this study was to develop a dynamical model of elastic fractal solids. This model is built on the concepts of the fractal continuum, fractal time, and the corresponding fractal derivatives. Also this ...
