Full State Feedback of DC-Motor Position and Speed Control Using LQR and Kalman Filter
(Cartagena de Indias, 2022)DC motors are used in various industrial, robotic and motion control applications, and generally angular position and speed are used as the main control variables. This paper presents the design of an LQR controller with ... -
Furan as Impurity in Green Ethylene and Its Effects on the Productivity of Random Ethylene–Propylene Copolymer Synthesis and Its Thermal and Mechanical Properties
(Cartagena de Indias, 2023)The presence of impurities such as H2S, thiols, ketones, and permanent gases in propylene of fossil origin and their use in the polypropylene production process affect the efficiency of the synthesis and the mechanical ... -
Fuzzy logic methodology to study the behavior of energy transformation processes based on statistics T2and Q
(Cartagena de Indias, 2020-10)In the processes of energy transformation, to carry out an adequate follow-up of the process parameters represent an opportunity to propose strategies to improve the processes' performance. For this reason, it is essential ... -

(Cartagena de Indias, 2021)The main cities of the Colombian Caribbean have recently reached the lowest unemployment figures in the country. However, they exhibit the highest informality rates. The objective of this paper is to analyse the situation ... -
Gender differences in math and reading: Performance, self-concept and expectations
(Cartagena de Indias, 2020)Previous studies show gender differences in math and language performance, mainly in adolescents. In this study, we aim to evaluate gender differences in self-concept, subjective value, expectations and academic performance, ... -
Generative Adversarial Networks for Cell Segmentation in Human Corneal Endothelium
(Cartagena de Indias, 2022)We generate synthetic images with a generative adversarial network (GAN) model trained with image patches from specular microscopy corneal endothelial cells. Preliminary results show it may be a suitable approach for ... -
Genericity of Continuous Maps with Positive Metric Mean Dimension
(Cartagena de Indias, 2021-11-02)M. Gromov introduced the mean dimension for a continuous map in the late 1990’s, which is an invariant under topological conjugacy. On the other hand, the notion of metric mean dimension for a dynamical system was introduced ... -
Genericity of Homeomorphisms with Full Mean Hausdorff Dimension
(Cartagena de IndiasCampus Tecnológico, 2024-04-18)It is well known that the presence of horseshoes leads to positive entropy. If our goal is to construct a continuous map with infinite entropy, we can consider an infinite sequence of horseshoes, ensuring an unbounded ... -
Girls Do Not Sweat: the Development of Gender Stereotypes in Physical Education in Primary School
(Cartagena de Indias, 2020-06-27)Despite efforts towards gender equality, from an early age, girls practice sport less than boys. Explaining this is paramount to psychology. Stereotypes about gender-appropriate behaviour play a key role in doing physical-sports ... -
