A través de este estudio se muestran los resultados de la aplicación de la exposición como estrategia metacognitiva utilizada por los estudiantes del IV semestre de la asignatura de Cálculo II de la Escuela Académica de Ingeniería Civil de la Universidad Nacional Intercultural de Quillabamba – Perú (UNIQ) durante el periodo de la pandemia (semestre 2021-II) en el que se tuvo que mediar el proceso de enseñanza y aprendizaje con el uso de herramientas y recursos tecnológicos diversos (Google meet, tableta wacon, openboard, presentaciones power point, etc.). Si bien esta estrategia también es usada en la fase presencial, la realidad educativa de la población estudiantil en un contexto virtual se ha tornado incierta y muchas veces el docente no tiene la certeza del nivel de logro de los aprendizajes de sus estudiantes haciendo necesaria la delegación de su responsabilidad a los estudiantes fortaleciendo, de este modo, la autonomía y autodeterminación. Por otro lado, y complementariamente, ayuda al fortalecimiento de habilidades orales, expresivas y de autoestima, de vital importancia en el marco del enfoque por competencias y en medio de crisis sanitaria ocasionada por la pandemia. El tipo de investigación es de análisis descriptivo comparativo y explicativo porque los resultados obtenidos luego de la aplicación de la estrategia mencionada proporcionaron información relevante sobre la influencia de la exposición como estrategia metacognitiva en el nivel logro de los aprendizajes (comunicación matemática, resolución de problemas y razonamiento y demostración) en la asignatura de Cálculo II en un contexto virtual mediado por herramientas tecnológicas. La metodología aplicada es de tipo cuantitativo, cualitativo y correlacional puesto que los resultados obtenidos luego de la aplicación de una ficha de observación del desempeño del estudiante antes y después de la observación de la exposición demuestran la correspondencia unívoca entre las variables de la investigación; determinándose el nivel muy bueno del uso de la exposición como herramienta metacognitiva a pesar de las limitaciones que se describen en el estudio.
Object recognition is essential in any surveillance system. Being important to identify the entry of intruders to a home or parking in restricted places, are some actions that are performed during a routine. However, the performance of these systems turns out to be inefficient because they remain static and in many cases their viewing angle turns out to be very limited. Therefore, we believe that a mobile surveillance system would be more efficient in reducing citizen insecurity in some closed housing estates, shopping centers or condominiums. Since being a mobile monitoring system would not have the disadvantages that present security systems have. Reason why, in this project is proposed the design and application of a patrol robot with autonomous navigatio n, which is able to monitor and travel a specified route. This path can be defined by the user, who when recording a waypoint the rob o t will move to that location in a relatively straight line, allowing the robot to navigate from one point to another preprogrammed. The navigation of robot will be done by GPS, but not only using this signal. Since, although it is true that this gives us information about the position or speed of a topological form, it does not show us if there are any obstacles in the way.For this we seek to merge GPS navigation with a sensor-based one, which collects information and with the help of a microprocessor this information serves for the robot to make decisions, since it is sought to be completely autonomous. Finally, the robot will be able to capture images with the help of a camera, storing them in its internal memory. These im a ges are then sent to the user in real time so that the user can analyze them and detect any anomaly act in the shortest possible time.
The linear positioning of hydraulic cylinders is used in industrial applications, such as the positioning of flight fins on airplanes, injection molding processes, rock drilling, etc. One of the most used control techniques is the PID (Proportional Integral Derivative) control, the problem with this technique is the tuning of its three parameters. In this work, the experimental identification of the transfer function of the system to be controlled was first done, using the MATLAB toolbox ident. Then the PSO (Particle Swarm Optimization) algorithm was implemented in MATLAB codes. Like any optimization algorithm it requires a performance index or cost function, in this research ITAE (Integral Time Absolute Error) was used. The codes were tested with research papers found in the literature, polished until they were ready for any transfer function. These algorithms were then tested in the transfer function previously identified, achieving satisfactory results in the simulations. Finally, those values of the PID parameters found were tested in the linear positioning module of the Oleohydraulics and Pneumatics Laboratory at the Universidad Católica de Santa María. Also achieving satisfactory results in the performance of the controlled system: minimum establishment time, minimum rise time and minimum overshoot, which matched with the values obtained by data acquisition. Finally, the Ant Colony algorithm (ACO) was tested, looking for better results. The best results were obtained with the ant colony algorithm, for 20 ants, with 1000 nodes, and 100 tours. For the system with load the best solution was Kp = 11.01, Ki = 5.51 and Kd = 3.71. The results were improved by making a better experimental identification of the system. The solution was also improved by increasing the number of tours and the number of nodes, increasing the computational cost. With the controller implemented, the setup time was reduced from 2.5 to 0.6 seconds without overshoot and with an error of less than 2 mm.
The purpose of this work was to apply the maintenance model based on RCM reliability, stipulated in Standards JA-1011, JA 10-12 and ISO 14224 and then analyze the effect on the conditions required by ISO / IEC 17025 approves the laboratory test processes. The application process is divided into the following stages: A first stage consisted in the application of an RCM questionnaire adapted to our need, which has served as an instrument to verify the current state of the laboratory organization, the equipment, and the perception of the functions of each one. These results allowed us to analyze the status with everyone, explain the objectives and define the work team. The second stage consisted of making a failure mode analysis, starting from the taxonomy and the division of systems, and defining the effect of failures by system. The results obtained above provided us with a real condition for the implementation of a maintenance calendar to the universal testing machine (EUT/C), proposing a work model based on Preventive and Predictive Maintenance, verifying the amount of maintenance hours, availability and reliability, such as parameters and indicators to improve. The last stage consisted of analyzing the maintenance procedures of the equipment, the selection of tasks and documents proposed to coordinate the information and monitoring required by ISO / IEC 17025 and internal laboratory standards.
