Authors:   Instituto Politécnico Nacional, México, Vite Leopoldo , Juárez-Ramiro Luis ,   Instituto Tecnológico Superior de Teziutlán, México, Rivera Flores Jorge ,   Instituto Tecnológico Superior de Teziutlán, México
Published: February 2024

In this article, we address the mechanical design and temperature control of an ecological egg incubator. A central component of the proposed incubator is the heating chamber, where the temperature is adjusted using a nickel/chromium heating element and a solar energy-based thermotank. Temperature regulation within the heating chamber is carried out through a PI controller. The tuning of the control gains is performed using the D-partition method, which allows obtaining stability regions of the closed-loop system in the presence of input time delay.

This state estimation is used for detecting faults to study the problem of cardiovascular anomalies that can originate from variations in physiological parameters and deviations in the performance of the heart’s mitral and aortic valves.
Harvesting Optimal Policy in Three Species Food Chain Model As an Optimal Control Problem with Path Constraints
Authors:   Universidad Autónoma Metropolitana, México, Cortez Karla , Solís-Daun Julio ,   Universidad Autónoma Metropolitana, México
Published: February 2024

In this paper, we address the issue of harvesting prey and intermediate predators in a tritrophic food chain. Our approach is based on a model that characterizes the interactions among the three species. We assume that the intermediate predator has alternative food sources (it is a generalist), while the top predator relies solely on the intermediate predator (it is a specialist). This model has been previously explored in the literature, but representing the harvesting effort as a scalar control variable. In this study, we treat it as a vector variable, offering a more comprehensive representation, particularly relevant for terrestrial species hunting. Our primary objective is to determine optimal harvesting policies that ensure the persistence of all three species. To achieve this, we formulate the problem as an optimal control problem with a finite horizon and path constraints. We present a numerical example solved using ICLOCS2.

In the ongoing search for efficient techniques to identify and validate dynamic models in various fields of science and engineering, the sparse identification of nonlinear dynamics (SINDy) algorithm has emerged as a promising tool to carry out this task. In this study, SINDy is applied to identify two chemical processes: pH neutralization and temperature control in a bioreactor. To accomplish this, firstly, the dynamic behavior of each system was modeled, and data were collected for both processes. Then, the studied algorithm was employed to identify the dynamic models of each process. Then, the identified models by SINDy were validated by comparing them with first-principles models. Several tests were conducted to assess the capability of SINDy-based models in predicting the dynamic behavior of the pH and temperature processes. The results revealed a satisfactory agreement between the models obtained by SINDy and the first-principles models. Hence, we show the SINDy algorithm could be reliable tool for identifying dynamic models for chemical processes.

Methodology to Obtain the State Feedback Gains for Lateral Control of the Autonomous Vehicles
Authors:   Universidad Autónoma de Ciudad Juárez, México, Gómez Gómez Jesús , Ponce Monarrez Israel ,   Universidad Autónoma de Ciudad Juárez, México, Vidal Portilla Luis ,   Universidad Autónoma de Ciudad Juárez, México
Published: February 2024

This paper introduces a methodology for deriving state feedback gains aimed at enhancing the lateral control of Autonomous Vehicles (AV). Autonomous Vehicles represent a groundbreaking technological advancement falling under the category of intelligent transportation systems. In developed nations, AVs are regarded as a potential solution to mitigate injuries resulting from road accidents. The AV system encompasses three distinct modules: Perception, Reference Generation, and Control. Among these, the Control module plays a pivotal role in ensuring the autonomy of the vehicle. Within the realm of existing literature, various lateral control systems have been documented. However, those relying on state feedback mechanisms have failed to provide a well-defined and systematic methodology for acquiring the requisite control gains. Furthermore, these approaches have not addressed the issue of varying vehicle speeds in the context of gain determination. Hence, the primary objective of this article is to present a comprehensive methodology for the systematic derivation of appropriate control gains for the AV lateral control system. The proposed methodology commences by positioning the system’s poles in accordance with the desired eigenvalues. Subsequently, the system is subjected to different sets of poles. Finally, an in-depth analysis of input and output data is conducted, with the aim of identifying the poles that most effectively minimize system errors.

Published: February 2024

The stability of a Single Machine Infinite Bus (SMIB) is enhanced through a nonlinear (NL) observer-based controller driven by load angle measurement with a constructive framework: (i) based on input-output feedback linearising control strategy, (ii) with assignable pole closed-loop (CL) linear dynamics, (iii) with a linear geometric (G) (Luenberger with integral action to eliminate the output estimation mismatch) observer, and (iv) rejection of model parameter errors and unmeasured input disturbances coupled with a simple tuning scheme. As a result, the proposed observer-based controller has a more systematic design and priority assurance of robust functioning with a suitable trade-off between transient response, robustness concerning model exogenous disturbances, control effort, and a relatively simple conventional tuning scheme in comparison with the traditional industrial controllers as the Power System Stabilizer and Automatic Voltage Regulator (PSS/AVR). The proposed controller is tested with a representative example through numerical simulation and compared with the traditional control scheme PSS/AVR.
Observer Design for a Lorenz Oscillator
Authors:   Universidad Nacional Autónoma de México, Granados-Salazar Christian , Espinosa-Pérez Gerardo ,   Universidad Nacional Autónoma de México, Rojas Michael ,   Universidad Nacional Autónoma de México
Published: February 2024

This article addresses the design problem of observers for the oscillator, focusing on the nonlinearities present in the model, which arise from the product between components of the state vector. These nonlinearities are particularly interesting because they allow obtaining an error dynamics that can be used to study the convergence properties of the observation scheme. In this sense, the design of a full-order observer is proposed, which is characterized by being a replica of the original system, with the addition of a correction term. Additionally, a numerical evaluation of the presented results is performed.

This paper describes a novel Maxim Power Point Tracking (MPPT) control for Photovoltaic Cells. The proposed control strategy uses a power monitor at the Solar Cell out-port. The proposed scheme locates the maximum power by estimating the measured power and corresponding first derivative. The continuous power estimation allows a Pulse Width Modulation circuit to control the switching of a step-up DC-DC converter, setting the solar cell in an average maximum power operation. The manuscript describes the control laws and electronic circuit implementation, exhibiting an improvement in voltage ripple compared to state-of-the-art solutions.

This paper proposes the design and construction of an amaranth compacting and cutting machine for Cooperativa agropecuaria Teocalli Tulyehualco S.C. from R.L. de C.V. The prototype is made up of a mechanical system and an electronic system interconnected to a control panel. The assignment of the dimensions of the bars is done through a question-and-answer interface. The programming for the compaction and cutting of the bars is done through a microcontroller. Control signals from the microcontroller are sent to the power stage to drive the bipolar stepping motors. Thus, the rollers and knives are automatically adjusted for material compaction and crosscutting, respectively. In addition, the material conveyor belt is activated and the solenoid valve is activated to drop the guillotine and make the cut along the bar.

The on-line supervision of the process variables in a steam distillation plant is the main objective of this work. For this end, a nonlinear observer is designed based on the mathematical model proposed by Cerpa et al. (2008). The model has three differential equations, which reproduce the dynamics of the oil mass throughout the three stages of the process: (i) Loss of oil from plant material, (ii) Biphasic (oil-water) layer, (iii) Colected essential oil. The purpose of this work is to estimate the mass flow of oil lost by the plant material and the mass flow in the two-phase layer called the aqueous layer. Both process variables are difficult to measure physically, but it is important to know them because they can have an impact on the performance of the process. However, the mass of oil collected is considered to be an available variable to measure. By taking this consideration into account, a nonlinear Luenberger type observer is designed that takes as available output the mass of oil collected, and from this variable is able to estimate the dynamics of the unavailable variables.

Published: February 2024

This paper presents the design of an autopilot for the flight mode transition in a hybrid quadrotor/fixed-wing aircraft known as QuadPlane. The autopilot includes an attitude stabilization subsystem, a control subsystem for takeoff and landing in quadrotor mode, and a control subsystem to regulate the longitudinal speed of the aircraft and determine the transition from quadrotor to fixed-wing and vice versa. During pure fixed-wing and quadrotor modes, the pilot has control authority on the QuadPlane. The proposed scheme is validated using the X-Plane flight simulator.
The Journey to Improve the College of American Pathologists Cancer Biomarker Reporting Protocols
Authors: Baskovich Brett , Baras Alexander , Seethala Raja R. , Fitzgibbons Patrick L. , Schneider Frank , Harris Brent T. , Khoury Joseph
Published: February 2024

Context.—

Biomarker reporting has increasingly become a key component of pathology reporting, providing diagnostic, prognostic, and actionable therapeutic data for patient care.

Objective.—

To expand and improve the College of American Pathologists (CAP) biomarker protocols.

Design.—

We surveyed CAP members to better understand the limitations they experienced when reporting cancer biomarker results. A Biomarker Workgroup reviewed the survey results and developed a strategy to improve and standardize biomarker reporting. Drafts of new and revised biomarker protocols were reviewed in both print and electronic template formats during interactive webinars presented to the CAP House of Delegates. Feedback was collected, and appropriate revisions were made to finalize the protocols.

Results.—

The first phase of the CAP Biomarker Workgroup saw the development of (1) a new stand-alone general Immunohistochemistry Biomarker Protocol that includes reporting for ER (estrogen receptor), PR (progesterone receptor), Ki-67, HER2 (human epidermal growth factor receptor 2), PD-L1 (programmed death ligand-1), and mismatch repair; (2) a new Head and Neck Biomarker Protocol that updates the prior 2017 paper-only version into an electronic template, adding new diagnostic and theranostic markers; (3) a major revision to the Lung Biomarker Protocol to streamline it and add in pan-cancer markers; and (4) a revision to the Colon and Rectum Biomarker Protocol to add HER2 reporting.

Conclusions.—

We have taken a multipronged approach to improving biomarker reporting in the CAP cancer protocols. We continue to review current biomarker reporting protocols to reduce and eliminate unnecessary methodologic details and update with new markers as needed. The biomarker templates will serve as standardized modular units that can be inserted into cancer-reporting protocols.
Clot Waveform Analysis: From Hypercoagulability to Hypocoagulability: A Review
Authors: Marongiu Francesco , Ruberto Maria Filomena , Marongiu Silvia , Barcellona Doris
Published: February 2024

Context.—

Prothrombin time (PT) and activated partial thromboplastin time (aPTT) are coagulative screening tests used for the diagnosis of several pathologic conditions, such as liver failure, coagulation factor deficiencies, anti-phospholipid antibodies (lupus anticoagulant), and factor VIII inhibitors. A new test was developed several years ago to detect the amount of thrombin generated during plasma clotting, using low tissue factor concentrations and fluorogenic substrates, and it has since been used successfully in conditions ranging from hypocoagulable to hypercoagulable states. However, the test is expensive and difficult to perform in nonspecialized laboratories, and efforts have thus been made to find an economic and easily implementable test suitable for routine use, even in nonspecialist laboratories.

Objective.—

To evaluate clot waveform analysis (CWA) of PT and aPTT, aiming to show the dynamics of clot formation; that is, the “hidden” features of both tests. CWA can be implemented by using an automated coagulometer with dedicated software. The aim of this review was to evaluate whether CWA is able to detect both hypercoagulative and hypocoagulative states.

Data Sources.—

Using MedLine, we searched and retrieved articles relating to CWA. We only considered articles published in English, but with no limits in terms of article type, publication year, or geography.

Conclusions.—

CWA was shown to be a reliable test in patients with both hypercoagulable and hypocoagulable states. It represents a simple and inexpensive global test that can easily provide information on the behavior of the coagulation system. Both the first and second derivatives are computed by using dedicated software implemented with an on-board algorithm in a routine automated coagulometer.

Who’s Afraid of Militant Democracy, U.S. Style
Authors: Graber Mark A.
Published: February 2024

Yesterday, Professor Samuel Issacharoff asked “Can it really be that one public official in Maine can remove a national presidential candidate on her say-so?” Professor Issacharoff and I, as well as every proponent of disqualification I know of, agree on a basic point. Right-wing populist authoritarianism cannot be defeated by legal decree. Government by the people cannot be maintained by means other than government by the people. Disqualifying individual candidates who resort to violence when they lose the vote, however, does not raise the difficulties that concern Professor Issacharoff and are consistent with democratic rule.
Propuesta de un sistema de monitoreo de indicadores de salud mediante IOT para la toma de signos vitales.
Authors: Vela Mosquera Juan Carlos , Mera Otoya Erick Paul , Palacios Acosta Ever Alejandro
Published: February 2024

La presente investigación aborda la problemática existente en la obtención de parámetros de signos vitales en el sistema de salud en el Ecuador. La inaccesibilidad a estos datos debido a los elevados costos de exámenes de signos vitales genera una urgencia clínica. Instituciones educativas, como el Instituto Superior Tecnológico Luis Tello en la provincia de Esmeraldas, enfrentan demoras y dificultades al realizar la toma manual de signos vitales, almacenando la información de manera escrita o en hojas de cálculo, como Excel. Con el propósito de superar estas limitaciones, este artículo se centra en la propuesta de diseñar un sistema de monitoreo automatizado que garantice acceso remoto y captura eficiente de la información. Se emplearon enfoques tanto cualitativos como cuantitativos en esta investigación. Las pruebas de usuario se llevaron a cabo para recabar opiniones sobre la interfaz propuesta, mientras que un método comparativo evaluó la efectividad de la propuesta frente a equipos existentes en el mercado, la fase de información transmite los datos obtenidos de los sensores a la plataforma de IoT ThingSpeak y en paralelo en un conexión de área local a través de la plataforma VNC viewer para tener doble comunicación en caso de que los servidores de ThingSpeak fallen, aunque el sistema propuesto puede determinar parámetros básicos como la frecuencia cardíaca, temperatura y electrocardiograma (ECG), no es adecuado para brindar un análisis médico definitivo, pero ayuda para obtener datos básicos dentro de entornos educativos como el Instituto Superior Tecnológico Luis Tello en la provincia de Esmeraldas, Ecuador.
Performances do corpo negro feminino
Authors: Silva Patrícia Pereira da , Milani Maria Alice Sabaini de Souza , Moraes Paulo Eduardo Benites de
Published: February 2024

Tomando como ponto de partida a hipótese de Leda Maria Martins (2002) de que a subjetividade dos corpos se cria no e pelo poema por meio de um valor performativo, apresentamos um estudo do poema “SLAM BLUES – TAKE I”, de Roberta Estrela D’alva, para pensarmos a articulação entre corpo, performance e poética.  A partir do caráter performático da subjetividade feminina no processo de significação do poema, o presente artigo levanta reflexões que ajudam a pensar os modos como a partir da retomada da performance do dos corpos negros em espiral é possível imaginar processos de (re)configuração do sujeito lírico na poesia brasileira contemporânea produzida por mulheres. O estudo se vale de uma leitura crítica e cerrada do poema e conclui afirmando que os cruzamentos das matrizes africanas no processo da performance poética desafiam a lógica de uma subjetividade centrada no eu.
P65/NLRP3 Inflammasome Mediated Endothelial Cells Pyroptosis: A Novel Mechanism of In-Stent Restenosis
Authors: Han Baihe , Wang Gang , Hou Jingbo
Published: February 2024

Background: In-stent restenosis (ISR) is one of the key causes of ischemic events after coronary stent implantation, and endothelial cell death and inflammation are considered to be important mechanisms. Pyroptosis is a proinflammatory type of programmed cell death, the effects and underlying mechanisms of endothelial cell (EC) pyroptosis in ISR remains unclear. Method: According to our previous work, an ISR rabbit model was established. Rabbits were divided into sham operation group and stent group. Serum was collected at 0, 4, 8, and 12 weeks to detect interleukin (IL)-1β and IL-18 levels. Rabbits' vascular EC was collected to detect NLRP3, Caspase1, GSDMD and P65 expression by western blot. NLRP3 inhibitor (MCC950) and P65 inhibitor (Helenalin) were used to pretreat EC, cell viability, lactate dehydrogenase (LDH) level of supernatant and pyroptosis related protein expression were measured in different groups. Results: The serum levels of IL-1β and IL-18 gradually increased with time, and the levels at the site of stent implantation were higher than the peripheral level. EC viability decreased significantly in the stent group, and protein levels of NLRP3, caspase1 and GSDMD were higher than those in the sham group. MCC950 and P65 inhibitors can reverse these effects. Conclusions: EC pyroptosis mediated by P65/NLRP3 inflammasome axis may promote ISR, our results provide a potential intervention target for the treatment of ISR.

Securing Trust: Ethical Considerations in AI for Cybersecurity
Authors: Vemuri Naveen , Thaneeru Naresh , Tatikonda Venkata Manoj
Published: February 2024

The basic purpose of combining artificial intelligence with cybersecurity is to solve complex issues that emerge in the systems. This paper demonstrates a very distinct AI framework that can be embedded in cyber security, which rests upon this very basic foundation. The decisions that are made using artificial intelligence are not only transparent but are also simple to comprehend in vigorous situations of cyber security. This essay also discusses the ethical issues regarding AI, its risk, and accountability when some failure occurs in the context of cyber security. The efficacy of blending ethical systems into artificial intelligence for the purpose of improving safety and privacy is also demonstrated in this paper. We have suggested the consideration of an ethical system in every step of the development cycle of the system and it should be continuously monitored and updated for the prompt resolution of all the emerging issues in the system.

A workshop was held at the EDF offices in Washington, DC, on June 15 and 16, 2022, to discuss the current state of knowledge and to define productive courses of action in better determination and source apportionment of methane emission rates, and specifically, natural gas emission rates, in urban environments. The workshop involved 56 attendees from universities, government agencies, NGOs and the private sector, including representatives from relevant utilities. This report covers discussion of the knowledge base to date about urban sources of natural gas (NG) methane emissions, their relative magnitudes, and areas of uncertainty. Specific suggestions and ideas for future experiments to be conducted that could improve our understanding are presented. Next steps, including the creation of working groups for field experiments and/or a research coordination network are discussed.

La enseñanza de la matemática en el ámbito universitario ha experimentado una profunda transformación impulsada por el avance tecnológico. El objetivo general del presente artículo se centra en analizar el impacto de la tecnología en la enseñanza de las matemáticas a nivel universitario, evaluando las ventajas, desafíos y consideraciones éticas que acompañan esta transformación. La tecnología ha introducido una serie de elementos significativos, como la interactividad, la personalización del aprendizaje, el acceso a recursos en línea y la utilización de simulaciones y visualizaciones para facilitar la comprensión de conceptos matemáticos. Sin embargo, esta transformación también presenta síntomas preocupantes, como la desconexión entre docentes y estudiantes, la brecha digital y la dependencia tecnológica. Bajo una modalidad metodológica descriptiva, documental, con la aplicación de la técnica análisis documental para la interpretación de los teóricos. Se concluye que la tecnología facilita la interactividad, personalizar el aprendizaje y proporciona acceso a recursos en línea. La brecha digital persiste, lo que limita el acceso equitativo a estas herramientas. Se necesita una planificación cuidadosa para equilibrar la tecnología y las técnicas pedagógicas tradicionales, garantizando que los estudiantes desarrollen habilidades matemáticas sólidas

El objetivo del estudio fue determinar el nivel de engagement laboral en docentes; se realizó un estudio descriptivo, de corte transversal, con enfoque cuantitativo. La población estuvo conformada por 94 docentes de carreras de ciencias de la salud, de los cuales el 71,28% son mujeres, se encuentran entre los 30 y 49 años; para la recopilación de información se utilizó la escala Utrecht Work Engagement validada por Alpha de Cronbach (α=0,898). Entre principales resultados se evidencia que 56,39% de los docentes tienen un nivel alto de vigor, el 72,34% presentó un nivel medio de dedicación, el 61,70% un nivel medio absorción. Se determinó la relación entre el engagement y género de los docentes (Fisher=0,0041); en la dimensión dedicación existe relación con la carrera donde imparten clases los docentes (Fisher = 0,0879). No se encontraron diferencias estadísticamente significativas entre engagement según grupos de edad. Se concluye que la mayoría de los docentes tienen un engagement positivo, la dimensión mejor evaluada fue el vigor, la dimensión dedicación y absorción, no tuvieron niveles bajos, los docentes pueden padecer a lo largo del tiempo de estrés laboral para prevenirlo se debe realizar estrategias de mantenimiento y fortalecimiento del engagement laboral.
English Foreign Language Teachers’ Perception on The Use of Information and Communication Technology in Teaching English at SMKN 3 Langsa

Published: February 2024

This study aimed to explore English as a Foreign Language (EFL) teachers' perceptions of Information and Communication Technology (ICT) use in the English language teaching and learning process. The main purpose of this article is to explore the challenges of teacher face in using ICT. Two experienced teachers, recognized for their ICT integration, selected as the research subjects at SMK Negeri 3 Langsa. Employing a qualitative approach with a phenomenological design, data was collected through semi-structured interview. The findings reveal that both teachers acknowledge the positive role of ICT in enhancing teaching efficiency, student engagement, and diversifying learning resources. Despite encountering technical challenges, such as network disruptions, both teachers advocate for continuous teacher training, increased investment in ICT infrastructure, and innovative research to optimize ICT integration in English language teaching, ultimately contributing to a more effective learning environment.

Bollspelen i Johannes Schefferus Lappland. Fragment av nordiskt tidigmodernt idrottsliv med utblickar mot Island och de brittiska öarna
Authors: Lidström Isak
Published: February 2024

Sports historians have argued that the type of ball games commonin the British Isles, which were practiced by two teams andin which the ball was driven with sticks towards predeterminedgoals – i.e., hurling, shinty, bandy and hockey – were never playedin early modern Sweden. By highlighting descriptions of ballgames in Johannes Schefferus’s The History of Lapland (1674), asource previously ignored by sports historians, this article challengessuch a claim. One of the games described by Schefferus hassome similarities with the violent stick-and-ball game known inIcelandic sagas as knattleikr. Even greater similarities (such as thestart of the game with a face-off and the goals consisting of lineson the short edges) emerge when the game is compared with theScottish game of shinty. Thus, pre-modern Scandinavia does notappear to have been as isolated in terms of sports and games ashas been suggested by Swedish sports historians.
”Vår främste man är en liten kvinna”

This article highlights the daily press’s portrayal of the Swedish-Sami downhill skier Sarah Thomasson (1925-1996) during the period1949-1955. This study shows that the daily press’s portrayalof Thomasson was characterized by a dualistic and essentialistapproach to gender and ethnicity. The portrayal was marked bythe performative nature of the daily press. Thomasson was depictedpartly as an experienced and confident sportswoman, partlyas calm and non-competitive. Her hybridity – being conveyed asdownhill skier, Sámi and woman – was underlined in the in thepress coverage.

INVESTIGATION INTO MAGNETIC DRIVE SEALLESS PUMP FAILURE 3 FLARE GAS RECOVERY UNIT (FGRU)
Authors: Yahya M Farid , Malek M Faiz , Dan Reduan Mat
Published: February 2024

Failure investigation was conducted on magnetic drive centrifugal sealless pumps that had only been operating for six months and were already struggling to rotate. It was discovered that hydrocarbon sludge and other debris had blocked the lubricating channel, which is meant to provide pathways for cooling and lubricating the pump's inner magnetic and containment shell. Further investigation revealed that service water had contaminated the process fluid, precipitating calcium carbonate upon contact with the amine solution and clogging the flushing line. An additional duplex strainer was installed on the repaired pumps, and adequate precautions were taken to prevent water contamination.Keywords: cleanliness, internal flushing, contamination, clogging, duplex strainer
A CASE STUDY ON THERMAL ANALYSIS OF THE DISC BRAKE USED FOR HEAVY-DUTY CARS
Authors: Riyami Said S. Al , Chala Girma T. , Bernard Alex , Maawali Khalid Al
Published: February 2024

The brake system converts kinetic energy into thermal energy, resulting in a rise in the temperatures of the disc brake due to the friction caused by the pressure brake between the turntable and the brake pads. This study aimed to investigate the thermal analysis of the disc brake used for heavy-duty cars. The study focuses on designing the ventilated brake disc for a particular Mitsubishi Pajero car through modeling software and observing the performances of two materials such as grey cast iron and cast carbon steel. Holes were also included on the surface of the rotor to speed up heat dissipation during and after braking. By utilising SimulationXpress and ANSYS Workbench, stress and thermal behaviour were analysed to choose a material that would perform better and reduce the damage brought on by high temperatures. It was observed that cast carbon steel with 30 vanes showed better performance for stress analysis. The transient thermal analysis for solid and drill disc brakes using cast carbon steel showed that the disc brake with holes performs better, even reducing vanes from 36 to 30. The study proves that a drilled disc with 30 vanes and made of cast carbon steel is the better choice for performance and heat dissipation.
