    Análisis de sentimiento en acciones americanas : una herramienta para la toma de decisiones informada en el mercado financiero
    (Universidad EAFIT, 2023) Padilla Quintero, Javier Felipe; Brun, Xavier; Durango Gutiérrez, María Patricia
    This research study aims to assess the effectiveness of sentiment analysis in determining market perception of specific companies listed on the American stock market. The study focuses on employing sentiment analysis on collected news articles within a defined period. The specific objectives include gathering relevant news articles, employing natural language processing techniques for sentiment analysis, obtaining corresponding historical price data, and calculating the Pearson correlation between news sentiment and stock prices. The study endeavors to provide a deeper understanding of how sentiment analysis can impact the evaluation of companies and their market performance. The findings and analysis derived from this study can support investors in making more informed and data-driven decisions by considering market perception in conjunction with stock prices.

    Experimental Development of Fuzzy Controllers for Thermal and Pneumatic Processes
    (Universidad EAFIT, 2021-05-12) Hernandez-Mesa, Richard S; Moreno-Garcia, Francisco E; Castro-Casadiego, Sergio A; Medina-Delgado, Byron; Universidad Francisco de Paula Santander
    In this project, a Fuzzy control system is proposed in an industrial process training module with two independent systems between them, one thermal and the other pneumatic. The control algorithm is developed in Python language v3.6 executed by a Raspberry Pi B+, both controllers depend on the error and change in error that are updated in times of 2 s and 1 s, for temperature and pressure respectively, communication with the plants uses A/D and D/A converters, the thermal Fuzzy was analyzed with three temperature references [50,100 and 150]°C, with a rise time of 191 s, 360 s and 505 s; steady state error of 5.5%, 0.7% y 0.7%, in the pneumatic system the speed of change between references is evaluated from 10 psi to 15 psi varying the activation of the compressor at the beginning of the experiments, the settling times obtained are 111 s and 106 s, with the compressor off the result is 116 s and 88 s, besides a maximum excess of 13% with inherent oscillations to the type system that are in an acceptable range.

    Improving customer waiting time for medicine-retrieval center
    (Universidad Eafit, 2021-04-12) Plazas Escudero, David; Cárdenas-Rodríguez, Juan Sebastian; Restrepo Sierra, Mateo; Universidad Eafit, School of Sciences, Department of Mathematical Sciences
    Neuromedica is a Colombian pharmacy which provides treatment for people with neurological diseases. Recently, Neuromedica started attending patients from other pharmacy which led to a significant increase in the waiting time. In this pharmacy, people are classified and attended due to certain priorities. The data, given by Neuromedica, is analyzed using boxplots, Kruskal-Wallis and Kolmogorov-Smirnov tests with Python’s library Scipy. The objective of this work is to determine the number of assistants and queue logistic such that the waiting time has a significant reduction, with the purpose to provide a satisfactory level of service. A discrete-event simulation model was created and implemented in Python. A heuristic approach to minimize the waiting time is used. Additionally, a sensitivity analysis is made on the assumed distributions.
