Energy efficiency and productivity of a Pressure Swing Adsorption plant to purify bioethanol: Disturbance attenuation through geometric control Jesse Y. Rumbo-Morales, Gerardo Ortiz-Torres, Felipe D.J. Sorcia-Vázquez, Carlos Alberto Torres-Cantero, Jair Gómez Radilla, Mario Martínez García, Julio César Rodríguez-Cerda, Antonio Márquez Rosales, Moises Ramos-Martinez, Juan Carlos Mixteco-Sánchez, Mayra G. Mena-Enriquez, Mario A. Juarez Digital Chemical Engineering, 2025 Biofuels produced from renewable raw materials, in this case bioethanol, provide a sustainable and renewable energy source for the future, as bioethanol positively impacts the economy, the environment, and society. Bioethanol is an alternative and immediate solution to mitigate the main greenhouse gases generated by transportation and industries that use fossil fuels. However, to produce bioethanol it is necessary to use advanced dehydration processes or technologies. Currently, azeotropic distillation, extractive distillation, and the Pressure Swing Adsorption (PSA) process using selective zeolites on water molecules are used. This PSA process has shown high selectivity, high yield, and high energy efficiency for producing anhydrous ethanol compared to other technologies. This work aims to implement automatic control laws (geometric and PID) to maintain stable the desired purity (99.5%), have higher bioethanol recovery and generate higher productivity using less energy. Both controllers performed adequately on the PSA bioethanol-producing plant, however, the geometric control presented greater robustness against disturbances, achieving to maintain stable bioethanol purity above 99% by wt, generating a recovery of 73.62%, with productivity of 59.07 k m o l and using an energy efficiency of 59.21%. Using this control law, it was possible to use the entire length of the columns to adsorb a greater amount of water molecules and achieve higher production.
Employability and its relationship with the competency-based approach, teaching methodologies, and assessment in higher education: a systematic review Ricardo Pérez Zúñiga, Mario Martínez García, Francisco Eduardo Oliva Ibarra Frontiers in Education, 2025 Introduction The employability of university community members depends on the skills they acquire, as well as on the teaching and evaluation methodologies used. The integration of these elements into academic programs is crucial for successful job placement. Methods The PRISMA methodology was followed for a systematic review of literature indexed in Web of Science and Scopus, based on a critical analysis of the literature. Results The results primarily encompass undergraduate, graduate, and postgraduate. The training is predominantly multidisciplinary, emphasizing skills such as communication, teamwork, problem-solving, and critical thinking. Teaching methods utilize real-world environments, while assessments employ Likert scales and task-based evaluations. Discussion Employability is a key objective in higher education and should be integrated at all academic levels. The most effective teaching methods are experiential and practical, as they simulate real-world work environments. Core competencies include communication, teamwork, problem-solving, and critical thinking. In addition, newer competencies such as ethics, professionalism, and a capacity for lifelong learning are increasingly important. Finally, assessment methods must be aligned with these practical approaches.
Pedagogical and evaluative competencies for the 21st century in molecular biology education and their relationship with honors programs: a systematic literature review Ricardo Pérez Zúñiga, Mario Martínez García, Marina Campos-Valdez, Laura V. Sánchez-Orozco Frontiers in Education, 2025 IntroductionPedagogical and evaluative competencies for the 21st century are essential in molecular biology. Literature suggests that teaching methods should assess both knowledge and disciplinary skills, as this approach is a prerequisite for student employability in biomolecular sciences.MethodsIn this systematic review, we conducted a search in Web of Science and Scopus, selecting 55 studies that met the inclusion criteria for the development of this research. The keywords used in WoS and Scopus were “molecular biology” and “students,” limited to articles published between 2020 and 2024.ResultsThis study identified a set of key competencies for the practice of molecular biology. However, it was observed that other equally relevant competencies received less attention in the analyzed reports. Honors programs implemented by universities promote innovative methodologies and technologies to enhance academic performance in molecular biology. These programs also encourage active teaching, which fosters students’ overall development.ConclusionThe most frequently noted molecular biology competencies were critical thinking, collaboration, problem-solving, communication, and creativity. In contrast, other important skills such as research, reading, self-directed learning, motivation, and digital literacy were less emphasized, despite their relevance and connection to honors programs. In terms of teaching modalities, the face-to-face laboratory teaching was the most highly valued for its practical approach, followed by the hybrid approach. The traditional mode ranked third, while the virtual mode, despite its advantages, came in fourth. Desktop-based exams predominate as an evaluative tool, but there is a gap in this approach, since all the evaluation tools detected in this study mainly measure theoretical knowledge, omitting competency evaluation. This contradiction is relevant, as today’s employers demand precisely such competencies. Implementing honors programs is one way to address this gap by focusing on developing skills that align with current labor demands.
Sleep Apnea Classification Using the Mean Euler–Poincaré Characteristic and AI Techniques Moises Ramos-Martinez, Felipe D. J. Sorcia-Vázquez, Gerardo Ortiz-Torres, Mario Martínez García, Mayra G. Mena-Enriquez, Estela Sarmiento-Bustos, Juan Carlos Mixteco-Sánchez, Erasmo Misael Rentería-Vargas, Jesús E. Valdez-Resendiz, Jesse Yoe Rumbo-Morales Algorithms, 2024 Sleep apnea is a sleep disorder that disrupts breathing during sleep. This study aims to classify sleep apnea using a machine learning approach and a Euler–Poincaré characteristic (EPC) model derived from electrocardiogram (ECG) signals. An ensemble K-nearest neighbors classifier and a feedforward neural network were implemented using the EPC model as inputs. ECG signals were preprocessed with a polynomial-based scheme to reduce noise, and the processed signals were transformed into a non-Gaussian physiological random field (NGPRF) for EPC model extraction from excursion sets. The classifiers were then applied to the EPC model inputs. Using the Apnea-ECG dataset, the proposed method achieved an accuracy of 98.5%, sensitivity of 94.5%, and specificity of 100%. Combining machine learning methods and geometrical features can effectively diagnose sleep apnea from single-lead ECG signals. The EPC model enhances clinical decision-making for evaluating this disease.
Self-Adaptable Software for Pre-Programmed Internet Tasks: Enhancing Reliability and Efficiency Mario Martínez García, Luis Carlos G. Martínez Rodríguez, Ricardo Pérez Zúñiga Applied Sciences Switzerland, 2024 In the current digital landscape, artificial intelligence-driven automation has revolutionized efficiency in various areas, enabling significant time and resource savings. However, the reliability and efficiency of software systems remain crucial challenges. To address this issue, a generation of self-adaptive software has emerged with the ability to rectify errors and autonomously optimize performance. This study focuses on the development of self-adaptive software designed for pre-programmed tasks on the Internet. The software stands out for its self-adaptation, automation, fault tolerance, efficiency, and robustness. Various technologies such as Python, MySQL, Firebase, and others were employed to enhance the adaptability of the software. The results demonstrate the effectiveness of the software, with a continuously growing self-adaptation rate and improvements in response times. Probability models were applied to analyze the software’s effectiveness in fault situations. The implementation of virtual cables and multiprocessing significantly improved performance, achieving higher execution speed and scalability. In summary, this study presents self-adaptive software that rectifies errors, optimizes performance, and maintains functionality in the presence of faults, contributing to efficiency in Internet task automation.
Total Harmonic Distortion Reduction in Multilevel Inverters through the Utilization of the Moth–Flame Optimization Algorithm Adolfo R. Lopez, Oscar A. López-Núñez, Ricardo Pérez-Zúñiga, Jair Gómez Radilla, Mario Martínez-García, Maria A. López-Osorio, Gerardo Ortiz-Torres, Mayra G. Mena-Enriquez, Moises Ramos-Martinez, Juan Carlos Mixteco-Sánchez, Carlos Alberto Torres-Cantero, Felipe D. J. Sorcia-Vázquez, Jesse Y. Rumbo-Morales Applied Sciences Switzerland, 2023 This paper shows the implementation of the Moth–Flame Optimization algorithm in a Cascade-H multilevel inverter with five and seven levels to determine the optimal switching sequence of the inverter’s semiconductor devices. The algorithm was coded in Matlab software, and the obtained switching sequences were implemented in a Cascade-H multilevel inverter laboratory prototype, where the output voltage waveform was obtained using a digital oscilloscope. The experimental Total Harmonic Distortion was obtained using a power quality analyzer. The experimental results show the improvement of the Total Harmonic Distortion in the voltage output. These results were compared with other papers in the literature with different metaheuristic methods concerning the same modulation. These findings demonstrate the feasibility of employing the Moth–Flame Optimization Algorithm to significantly reduce the Total Harmonic Distortion, obtaining a lower value than most analyzed papers.
Automatic Equipment to Increase Sustainability in Agricultural Fertilization Mario Martínez García, Silvia Ramos Cabral, Ricardo Pérez Zúñiga, Luis Carlos G. Martínez Rodríguez Agriculture Switzerland, 2023 The purpose of the study was to design a device for the dissolution of fertilizers for agricultural use in an automatic and environmentally sustainable way to facilitate the work of farmers. To achieve this goal, an outdated blade design was used, which generates turbulent and laminar flows thanks to the angle of inclination of its blades. In tests, the combination of these two flows gave a better result compared to laminar and turbulent flows separately. The best results were achieved by varying the spin and speed, the time between spins, and the rest time. The time it would take to dissolve the mixture was drastically reduced if it were conducted in the traditional way (manually) or compared with commercial mixers. In conclusion, the technique used for the dissolution of agricultural minerals is more effective and reduces time, energy, and effort. This was able to reduce the time necessary to dissolve the fertilizer by 93 percent compared to doing it manually and by 66 percent compared to using commercial mixers, in a solution of 100 L of water per 100 kg of ammonium sulfate.
Fault Tolerant Control via Input-Output Linearization Method for LED-Driver Using a Boost Converter Gerardo Ortiz Torres, Jesse Y. Rumbo-Morales, Rene Osorio Sanchez, Mario Martinez-Garcia, Marco Antonio Rodriguez Blanco IEEE Access, 2023 This paper proposes a method based on an input-output linearization controller with a nonlinear adaptive observer, in order to achieve both an effective light-emitting diode (LED) current tracking and an actuator fault tolerant controller strategy for a LED-driver, using a boost converter. The partial fault is presented as a Loss of Effectiveness (LoE) in the embedded control target by considering that it generates a faulty Pulse-Width Modulation (PWM) signal. Also, faults of energy storage components in the power system are considered as actuator partial faults. An internal stability analysis is presented to ensure the feasibility of the nonlinear controller design. The nominal feedback controller is able to compensate for the nonlinearity of the system exactly, thus yielding a linear control loop. Furthermore, a nonlinear adaptive observer is considered for fault estimation. When the actuator fault is detected and estimated correctly, fault accommodation and reconfiguration strategies are performed to reduce the fault’s effect. The controller and observer gains are tuned using genetic algorithm techniques to have a desired closed-loop and fault estimation error response. Finally, simulations results are done in order to illustrate the effectiveness of the proposed methodology.
Design and Control Applied to an Extractive Distillation Column with Salt for the Production of Bioethanol Carlos Alberto Torres Cantero, Ricardo Pérez Zúñiga, Mario Martínez García, Silvia Ramos Cabral, Manuela Calixto-Rodriguez, Jorge Salvador Valdez Martínez, Mayra Guadalupe Mena Enriquez, Abraham Jashiel Pérez Estrada, Gerardo Ortiz Torres, Felipe de J. Sorcia Vázquez, Azael García Rebolledo, Jesse Yoe Rumbo Morales Processes, 2022 Extractive distillation with salts, unlike other dehydration technologies, is better due to the null toxicity that exists in the distillate, since salt cannot be evaporated. With this distillation technology, it is possible to obtain a high concentration of ethanol, however, there are still problems in the control of the distillation columns in the presence of disturbances. The present work deals with the simulation and control of an extractive distillation column using CaCl2 as a separating agent, for which the Aspen Dynamics® simulator is used. The measurement and control of the ethanol composition are carried out by means of temperature, in addition, four control structures are evaluated and compared. These structures are L, D, LV, and DV, which are the most common in conventional distillation, and their performance is measured by means of deterministic indicators applying changes (disturbances) of composition and the flow rate in the main feed of the column. The most relevant results of this work lead to the fact that by applying a controller, it is possible to maintain the desired purity above the international purity standards (99% ethanol) that govern biofuels.
Simulation and State Feedback Control of a Pressure Swing Adsorption Process to Produce Hydrogen Mario Martínez García, Jesse Y. Rumbo Morales, Gerardo Ortiz Torres, Salvador A. Rodríguez Paredes, Sebastián Vázquez Reyes, Felipe de J. Sorcia Vázquez, Alan F. Pérez Vidal, Jorge S. Valdez Martínez, Ricardo Pérez Zúñiga, Erasmo M. Renteria Vargas Mathematics, 2022 One of the separation processes used for the production and purification of hydrogen is molecular sieve adsorption using the Pressure Swing Adsorption (PSA) method. The process uses two beds containing activated carbon and a sequence of four steps (adsorption, depressurization, purge, and repressurization) for hydrogen production and purification. The initial composition is 0.11 CO, 0.61 H2, and 0.28 CH4 in molar fractions. The aim of this work is to bring the purity of hydrogen to 0.99 in molar fraction and implement controllers that can maintain the desired purity even in the presence of the disturbances that occur in the PSA process. The controller design (discrete PID and state feedback control) was based on the Hammerstein–Wiener model, which had an 80% fit over the rigorous PSA model. Both controllers were validated on a virtual plant of the PSA process, showing great performance and robustness against disturbances. The results obtained show that it is possible to follow the desired trajectory and attenuate double disturbances, while managing to maintain the purity of hydrogen at a value of 0.99 in molar fraction, which meets the international standards to be used as a biofuel.
