Nowadays the thermal load of components for alternating internal combustion engines becomes higher and higher. Therefore, not only the materials and components have to be enhanced, but also the way in which we design cooling systems acquires a larger importance. Optimization of cooling systems design is necessary because of several reasons. On the one hand the remit and requirement to the components of the present must be accomplished and on the other hand, a more important point has to be respected, which is reducing fuel consumption, also closely related to the emissions of exhaust gases. The best way to design and model these systems is to create and use simulation tools. The optimal designing of cooling systems permits saving time during the construction process, reducing the amount of required experimental work, thus improving the economic aspect. This paper is about illustrating the computer program “Flowmaster” (a thermal, hydraulic simulation software) to represent a real circuit of a locomotive into the so called “simulation software”. It is built the virtual model of the cooling system of the EMD 12N-710G3B-MUI engine installed in a locomotive, using the FlowMaster thermofluid-dynamic circuit simulation program. The models generated can be used to predict the performance of the cooling system under different conditions such as cold start and working under a singular drive cycle.

This project addresses issues of design and development of a prototype of a humanoid robot with interactive movements, feedback control, and detection systems based on the open-source platform of Inmoov. The robot is designed in a way that can perform fluid movements naturally in the arms, fingers, and neck. By integrating advanced technologies such as artificial intelligence through OpenAI's GPT, the robot achieves computer vision capabilities using a stereo camera with depth sensing, specifically the Oak-D with Depth AI. These different technological supports allow the robot to recognize, identify and manage to respond to its environment with interpretation and reading of gestures, voice commands, thus offering a more rewarding experience as a fluid interaction in a personalized way. All the complementation of work implementing a customized and efficient control system for the management of servo motors using programmable modules such as PCA9685 optimizing the accuracy of movements, good skill with care to perform the calibrations.

This research proposes a comprehensive methodology for the optimization of well drilling, addressing geological, geomechanical, technical and economic aspects. Using data from the Sheshea 126-17-1X well, located in the Ucayali basin, electrical logs from the LAS archives were examined to interpret the lithology of the subsurface formations. The study focuses on the calculation of the Mechanical Specific Energy (MSE) and its correlation with the mechanical properties of the rock, such as Unconfined Compressive Strength (UCS) and Confined Compressive Strength (CCS), complemented by the analysis of operational parameters such as Weight on Bit (WOB), Revolutions per Minute (RPM) and Torque. Likewise, seismic velocities (Vp and Vs) and elastic properties (Young's Modulus and Poisson's ratio) were calculated to determine the stiffness and deformability of the formations. According to these analyses, optimal Weight on Bit (WOB) ranges were determined, and an optimal Rate of Penetration (ROP) was obtained, achieving increases in ROP of up to 8.41%, a decrease in drilling time between 5.3% and 7.76%, and savings of a maximum of 8.33%. It is concluded that the integration of a geomechanical and operational analysis makes it possible to identify and correct inefficiencies regarding energy consumption during drilling, optimizing the process and reducing operating costs.

Given the need for a machine capable of conducting tensile tests on plastics, specifically PLA, the creation and development of such a machine has been proposed to be used and tested by Mechatronics Engineering students at the Technological University of Bolívar. Considering the importance of plastics in engineering, due to their versatility and durability, and their widespread use in various applications, it is essential to understand their mechanical behavior under different conditions, in this case, under tension.

The main objective is to provide an educational and practical tool that allows students not only to observe but also to actively participate in conducting these tests, overcoming the limitation that only laboratory assistants have access to this equipment. This initiative aims to enhance the understanding and handling of plastics in practical and research applications. The development of this machine will start with conceptual design, addressing both theoretical and practical aspects to ensure that all necessary requirements for its proper operation are met. The ASTM D638 standard will be followed, which establishes standard procedures for tensile tests on plastics, ensuring that the tests are conducted in a standardized and safe manner. This will minimize errors and accidents, creating a safe, competent, and enjoyable environment for regular use by students and other interested groups.
