Method of asymptotic partial decomposition of domain for multistructures
(Taylor & Francis, 2017)
Method of asymptotic partial decomposition of a domain (MAPDD) proposed and justified earlier for thin domains (rod structures, tube structures) is generalized and justified for the multistructures, i.e. domains consisting ...
Junction of models of different dimension for flows in tube structures by Womersley-type interface conditions
(Society for Industrial and Applied Mathematics Publications, 2019)
© 2019 Society for Industrial and Applied MathematicsThe method of asymptotic partial decomposition of a domain proposed and justified earlier for thin domains (rod structures, tube structures consisting of a set of thin ...

On generalized multiscale methods for flow in complex porous media and their applications
(Bogotá - Ciencias - Doctorado en Ciencias - MatemáticasFacultad de CienciasBogotá,ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2023-06-27)
In this document, the Generalized Multiscale Finite Element Method (GMsFEM) is studied, which deals with constructing multiscale spectral basis functions designed for high-contrast multiscale problems. The multiscale basis ...
Subordination principle, Wright functions and large-time behavior for the discrete in time fractional diffusion equation

Operator theory in dynamical network systems
(Universidad Nacional de ColombiaBogotá - Ingeniería - Doctorado en Ingeniería - Ingeniería EléctricaDepartamento de Ingeniería Eléctrica y ElectrónicaFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-08-25)
We provide a data-driven synthesis framework for some complex systems. The proposed fra- mework relies on the linear operator theory involving the Koopman operator. Our first results employ Koopman-based lifting for the ...
Distributionally robust optimization: a novel approach with decision-dependent ambiguity sets and an application to mode estimation
(Universidad de los AndesDoctorado en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2023-04-14)
This Ph.D. thesis explores stochastic optimization from a Distributionally Robust perspective, focusing on two significant themes: the innovative use of decision variable-dependent ambiguity sets in Distributionally Robust ...
Diseño de bombas centrífugas utilizando el método de optimización topológica y computación paralela en la nube
(Universidad Nacional de ColombiaMedellín - Minas - Maestría en Ingeniería MecánicaDepartamento de Ingeniería MecánicaFacultad de MinasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2021-12-14)
Este trabajo se focaliza específicamente en bombas centrífugas de flujo radial, cuya componente de velocidad axial no es considerada en comparación con las velocidades tangenciales y radiales, dando lugar al diseño de ...
