    • A Mathematical Model for the Optimization of the Non-metallic Mining Supply Chain in the Mining District of Calamarí-Sucre (Colombia) 

      Ospina-Mateus, Holman; Montero-Perez, Jairo; Acevedo Chedid, Jaime; Salas-Navarro, Katherine (Cartagena de Indias, 2020-10-08)
      This article presents a mathematical model of the Supply chain of non-metallic mining. The model considers uncertainty scenarios in materials, elements for capacity planning in a multilevel chain and with multiple products. ...

    • Different Experimental and Numerical Models to Analyse Emptying Processes in Pressurised Pipes with Trapped Air 

      Paternina-Verona, Duban A; Coronado-Hernández, Oscar E.; Espinoza-Román, Héctor G.; Fuertes-Miquel, Vicente S.; Ramos, Helena M. (Cartagena de Indias, 2023-06-29)
      In hydraulic engineering, some researchers have developed different mathematical and numerical tools for a better understanding of the physical interaction between water flow in pipes with trapped air during emptying ...

    • Fatigue Life Estimation Model of Repaired Components with the Expanded Stop-Hole Technique 

      Velilla-Díaz, Wilmer; Guillén-Rujano, Renny; Pérez-Ruiz, José David; López de Lacalle, Luis Norberto,; Palencia, Argemiro; Maury, Heriberto; Zambrano, Habib R. (Cartagena de IndiasCampus TecnológicoIngeniería Mecánica, 2024-02-01)
      Fatigue crack growth tests are conducted to assess the efficacy of the stop-hole crack repair method. This straightforward and widely adopted technique involves drilling a hole at the crack tip and subsequently enlarging ...

    • IV Encuentro Matemático del Caribe - Memorias 2022 

      Muentes Acevedo, Jeovanny de Jesus; Payares Guevara, Carlos R.; Muñiz, Jorge Luis; Cabarcas Sánchez, Andrea Estefanía (Cartagena de IndiasCampus Tecnológico, 2023-07-18)
      El Encuentro Matemático del Caribe (Página Web IV Encuentro Matemático del Caribe) tiene como finalidad reflexionar sobre el quehacer matemático y la enseñanza de las Matemáticas en el Caribe colombiano. Así mismo, extender ...

    • Mathematical model for assigning an optimal frequency of buses in an integrated transport system 

      Quintero J.S.M.; Martínez Santos J.C. (Springer Verlag, 2018)
      This paper proposes a mathematical model to estimate the frequency setting of the buses for a specific route on any given hour in public transportation systems. This model can be used for three different purposes: determine ...

    • On the computation of LFSR characteristic polynomials for built-in deterministic test pattern generation 

      Acevedo Patiño, Óscar; Kagaris D. (IEEE Computer Society, 2016)
      In built-in test pattern generation and test set compression, an LFSR is usually employed as the on-chip generator with an arbitrarily selected characteristic polynomial of degree equal, according to a popular rule, to ...

    • Optimal Power Dispatch of Dispersed Sources in Direct-Current Networks with Nonlinear Loads 

      Montoya Giraldo, Oscar Danilo; Garrido Arévalo, Víctor Manuel; Grisales-Noreña, Luis Fernando (Cartagena de Indias, 2021-12-10)
      The problem of the optimal power dispatch of dispersed generators in direct-current networks under the presence of nonlinear loads (constant power terminals) is addressed through a combinatorial optimization strategy by ...

    • Transient phenomena generated in emptying operations in large-scale hydraulic pipelines 

      Romero, Guillermo; Fuertes Miquel, Vicente S.; Coronado Hernández, Óscar Enrique; Ponz-Carcelén, Román; Biel-Sanchis, Francisco (Cartagena de Indias, 2020-08-18)
      Air pockets generated during emptying operations in pressurized hydraulic systems cause significant pressure drops inside pipes. To avoid these sudden pressure changes, one of the most widely used methods involves the ...

    • VRP model with time window, multiproduct and multidepot 

      Ruiz-Meza, José; Montes, Isaid; Pérez, Arnoldo; Ramos-Márquez, María (Cartagena de Indias, 2020-02-15)
      With the increase in the transfer of products in supply chains, the organization of routes requires a complex allocation insofar as different environmental variables are considered, and VRP models are an efficient tool for ...
