Experimental Study of Mass Conservation Processes: a Look at the Teaching of Differential Equations from Modeling and Numerical Analysis
(Facultad educación artes y humanidades, 2024-06-23)Physical phenomena are typically described in different areas of knowledge using mathematical models. These models permit the assessment of variables associated with the process without building experimental setups. In order to achieve this goal, it is necessary to formulate a differential equation that, depending on the number of variables, can be partial or ordinary type. In this context, the present work evaluates the mass balance for an open system from a numerical and mathematical perspective, and then experimentally validates the results obtained. The analytical solutions of the mathematical ... -

In-plane behavior of clay blocks externally reinforced
(Facultad educación artes y humanidades, 2021)The objective of this research work was to determine the resistance to cutting of clay block walls of size 1.20 m × 1.20 m without and with external reinforcement. Blocks of width equal to 0.10 m were used for four manufacturers, one located in Oca˜na, Colombia, and three more established in San Jos´e de C´ucuta, Colombia. Reinforcement with electrowelded mesh is an alternative to reduce the seismic vulnerability of homes in areas of intermediate and high seismic risk. Oca˜na, Colombia, is located in an intermediate seismic hazard zone and therefore the use of simple masonry in homes is ... -

Perfil, retos y desafíos del estudiante universitario en el siglo XXI
(Facultad educación artes y humanidades, 2021-01-24)La globalización, los medios de información y comunicación, la web 2.0 y la revolución industrial, ha generado cambios metodológicos que intentan favorecer el autoaprendizaje; es así que la educación no se centra en la enseñanza sino en el aprendizaje; el educador, deja de ser transmisor y pasa a ser orientador o dinamizador; el alumno por su parte, se convierte en protagonista y autogestionador del conocimiento. A la luz de ello, es importante que el estudiante, siendo protagonista de su aprendizaje, reflexione en torno al mismo proceso en el que está sumergido. Este artículo, intenta ... -
Polinomial chaos expansion applied to limit state functions
(Facultad educación artes y humanidades, 2021-01-20)In structural projects, ensuring system performance within the established specifications with a maximum level of safety and taking into account the economic constraints of the project is one of the main objectives of structural design. The risks to which any physical system is subjected are called failure probability and are assessed by applying structural reliability analysis methods. The objective of the structural reliability analysis is to ensure that the strength of the elements of the structure is greater than the imposed strength demand over the service life of each of the structural ... -

System to monitor and locate water leaks using LabVIEW software
(Facultad educación artes y humanidades, 2020)Water pipelines are prone to critical failures due to aging, corrosion, and external factors. These failures can lead to water leaks in the pipeline, which in turn can cause property damage and environmental contamination if not detected in time. This work presents a system for monitoring and locating water leaks using LabVIEW software. The system describes the mathematical model used to locate the leak, which is implemented in a virtual instrument, obtaining the flow and pressure behavior of the system in the presence and absence of leaks in a transient state through a virtual platform ... -
