Smart Corrosion Monitoring in AA2055 Using Hidden Markov Models and Electrochemical Noise Signal Processing by Martínez Ramos, Cynthia, Gaona Tiburcio, Citlalli, Estupiñan López, Francisco Humberto, Cabral Miramontes, José Ángel, Maldonado Bandala, Erick, Almeraya Calderón, Facundo, Nieves Mendoza, Demetrio, Baltazar Zamora, Miguel Ángel, Landa Ruiz, Laura, Galván Martínez, Ricardo, Almeraya Calderón, Facundo

“…This work explores the application of Hidden Markov Models (HMMs) for the classification and reconstruction of corrosion mechanisms in the aerospace-grade aluminum alloy AA2055 from the signals obtained by electrochemical noise (EN) analysis. Using the PELT algorithm to segment the signal based on relevant changepoints, distinct corrosion states within the segments are isolated and identified, including general, localized, and mixed corrosion based on statistical signal features, which are used to create the probabilistic structure of HMMs through the initiation, transition, and emission matrices. …”

A Real-Time SOSM Super-Twisting Technique for a Compound DC Motor Velocity Controller by Morfin, Onofre A., Castañeda, Carlos E., Valderrabano González, Antonio, Hernandez González, Miguel, Valenzuela, Fredy A.

“…bstract: In this paper, a real-time robust closed-loop control scheme for controlling the velocity of a Direct Current (DC) motor in a compound connection is proposed. This scheme is based on the state-feedback linearization technique combined with a second-order sliding mode algorithm, named super-twisting, for stabilizing the system and achieving control goals. …”

La esofagitis eosinofílica. ¿El Norte contra el Sur? Enfoque mecanicista bio-económico-social e implicaciones clínicas by García Compeán, Diego, González González, José Alberto, González Moreno, Emmanuel Irineo, Maldonado Garza, Héctor Jesús

“…No obstante, el carácter epidémico de la enfermedad sugiere que las causas ambientales son más poderosas. Con base en hipótesis publicadas, así como en los estudios epidemiológicos, en la presente revisión se discutirán algunas de las posibles causas de la disparidad de prevalencia de la EEo entre ambos tipos de países. …”
