The review includes studies that apply numerical and analytical models to assess stresses and strains under different operating and load conditions. Research that considers the effects of temperature, pressure, and material properties on string performance is also examined. Work that has developed advanced computational simulations to represent the transient state of strings and their interaction with the well environment is highlighted. In addition, case studies that have validated these models through experimental and field data are discussed. The review provides a comprehensive view of current techniques and their applications, identifying significant advances and remaining challenges in evaluating oil string stresses and deformations under transient conditions.</p> Jose Salazar Luis Rosales-Romero Franyelit Suarez-Carreno Copyright (c) 2024 Jose Salazar, Luis Rosales-Romero, Franyelit Suarez-Carreno 2024-07-18 2024-07-18 5 16 7 14 10.47460/athenea.v5i16.73 Advances in composite materials based on industrial applications <p class="Abstract" style="text-indent: 0cm;"><span style="font-family: 'Segoe UI',sans-serif; font-weight: normal;">This work aimed to evaluate the applicability and benefits of composite materials in various industrial contexts. Through surveys carried out in three mining industries and two in the electricity sector, aspects such as the frequency of use of different composite materials, the perceived benefits, and the main challenges faced in their implementation were analyzed. The results showed a high preference for carbon fiber and polymers due to their strength and lightness, highlighting the importance of durability and weight reduction as key benefits. However, high cost and availability of materials were identified as the main challenges. These findings underscore the need to continue investing in research and development to improve accessibility and reduce costs, optimizing the use of composite materials in industry.</span></p> Mario Augusto Rivera Valenzuela Copyright (c) 2024 Mario Augusto Rivera Valenzuela 2024-07-18 2024-07-18 5 16 15 23 10.47460/athenea.v5i16.74 Design of a criticality monitoring system for conveyor belt rollers <p>The document presents the design of a criticality monitoring system to visualize the condition of the rollers of a conveyor belt in real-time. The paper presents the design of a criticality monitoring system to visualize the status of the rollers of a conveyor belt in real time. This system uses a traffic light indicator to visualize the criticality of the equipment. This article defines the steps for the application of this model where a criticality level will be assigned to each roller through a programmable system with values ​​according to the current condition of these elements whose results provide valuable information to optimize maintenance tasks, reduce costs, and improve the availability of conveyor belts. The reports generated by this system make it a valuable tool for managerial management, since its implementation translates into greater safety, optimization of maintenance, extension of the useful life of the equipment, and better operational efficiency, ensuring the reliability and productivity of the industrial operations.</p> Argenis Jose Rodriguez Amaiz Copyright (c) 2024 Argenis Jose Rodriguez Amaiz 2024-07-18 2024-07-18 5 16 24 36 10.47460/athenea.v5i16.75 Simulation of remote control of a hexacopter with force feedback in semi-structured environments <p>This project simulates the flight of hexacopters in indoor environments. Through the design, modeling, and implementation of environments, it imitates semi-structured environments with static obstacles, including a house, a church, and a supermarket. Each environment displays different levels of difficulty. The application offers a choice between two models of hexacopters, achieving more useful and interactive, and it includes the option of force feedback, implemented with a force feedback joystick, warning the user about possible collisions, and giving the feeling of presence to the operator. The haptic device limits the force applied. The application focuses on three-dimensional scenes in semi-structured indoor environments, reproducing the environment variables (appearance, features, context) of a real system; in this sense, the implementation of the simulator is a low-cost technique that offers several possible scenarios without effects in the real world.</p> Natasha Guadalupe Danilo Chavez Copyright (c) 2024 Natasha Guadalupe, Danilo Chavez 2024-07-18 2024-07-18 5 16 37 47 10.47460/athenea.v5i16.76 Analysis of the integration of solar PV in buildings: design, implementation, and environmental benefits <p>In a world where the climate crisis and the need to reduce dependence on fossil fuels are becoming increasingly pressing, integrating solar PV in buildings is presented as a viable and sustainable solution. This work focuses on a detailed analysis of how solar PV can be designed, implemented, and maximized in urban environments. It explores the technical aspects of PV system design, the crucial steps in their implementation, and the significant environmental benefits that can be derived from their widespread use. The main results show that as cities grow and energy demand increases, the transition to renewable energy sources is not only an attractive option but a prevailing necessity to ensure a sustainable future. <strong>&nbsp;</strong></p> Cesar Geovanny Quilumbaqui Copyright (c) 2024 Cesar Geovanny Quilumbaqui 2024-07-18 2024-07-18 5 16 48 57 10.47460/athenea.v5i16.77
