Sign language to text translation using Python with LSTM neural networks
type: item
description: There is a difficulty that deaf people with speech disabilities face in communicating effectively with those who do not know sign language. Despite the existence of methods such as writing and lip-reading, these have limitations and are not always effective. The proposed solution includes developing a real-time sign language recognition system using convolutional neural networks and the MediaPipe platform. It detects and classifies the positions of hand points to identify letters. Gestures made in front of the camera are translated into letters that are stored to form paragraphs in a text box. The type of research is quantitative and experimental. Ultimately, the importance of sign language recognition and teaching is highlighted, especially in countries such as Colombia, where it has received significant recognition.

Implementation of a Real-Time Pressure and Tilt Angle Monitoring System for Mast Hoisting in NOV Rapid Rig 13 Equipment
type: item
description: This paper presents the implementation of a real-time monitoring system for mast hoisting operations in NOV Rapid Rig 13 equipment, using a distributed architecture with local data acquisition, processing, and visualization layers. The system simultaneously records hydraulic pressure and angular inclination data, enabling analysis of the dynamic behavior of hydraulic cylinders during hoisting operations. This data generated a static pressure curve to correlate pressure and inclination, representing the theoretical model of a three-stage hydraulic cylinder. This curve identified critical transitions and operational deviations, serving as the basis for defining alarm thresholds and enhancing operational oversight—empowering operators to make informed, safety-driven decisions. The results improve hoisting safety and establish a foundation for future automation and predictive maintenance strategies in hydraulic systems applied to drilling operations.

Voice Driven UML Modeling System for Visually Impaired Students in Software Engineering Education
type: item
description: Visual impairment limits students' access to object-oriented modeling environments that rely on graphical interfaces. Advances in Text-to-Speech (TTS) and Speech-to-Text (STT) technologies make it possible to consider mechanisms to compensate for this barrier, yet their adoption in educational platforms lacks evidence-based guidelines. This work aims to design, implement, and validate a voice-controlled UML modeling system that enables visually impaired students to create, edit, and query class and use-case diagrams. A four-phase methodology was followed: (i) requirements elicitation; (ii) modular architectural design with grammatical validation and the use of large language models (LLMs); (iii) implementation in Python 3.11, FastAPI, and cloud-based STT/TTS services; and (iv) technical evaluation using recognition accuracy, latency, and task-time metrics. The prototype executed 20 critical commands with a recognition accuracy of 97% and maintained full syntactic coherence in the UML models generated. The average times to complete creation, editing, and navigation tasks were 4.23 s, 6.78 s, and 5.24 s, respectively. The average TTS latency (1468 ms) exceeded the 500 ms target, identifying the NLP module as the main bottleneck. The system demonstrates technical feasibility and adheres to the defined accessibility guidelines (WCAG 2.2). Future improvements will focus on reducing TTS latency, expanding the command repertoire, and conducting large-scale usability evaluations (SUS).

Modal propagation analysis in waveguides for the design of evanescent wave photonic biosensors
type: item
description: This paper presents a modal propagation analysis of Strip and Rib waveguides with silicon and SU-8 cores, aimed at designing evanescent wave photonic biosensors. The objective was to determine structural configurations that optimize device sensitivity, focusing on single-mode and bimodal operating conditions. The study was conducted through numerical simulations using the Finite Element Method in COMSOL Multiphysics. Various combinations of materials, core heights of 220 and 600 nm, and operating wavelengths of 633 and 1550 nm were analyzed to evaluate the behavior of TE and TM propagation modes and the variation of the effective refractive index with respect to the waveguide width. The main outcome is a design table summarizing the optimal core width ranges for each configuration, serving as a practical tool for developing highly sensitive and manufacturable biosensors. Additionally, the presented methodology can be applied to the design of integrated photonic circuits in diverse fields such as telecommunications and optical computing.

Industrial control through reinforcement learning
type: item
description: In this article, the implementation of the flow control technique with artificial intelligence (DDPG) is presented in a fully instrumented functional prototype with industrial sensors and actuators, simulating flow recirculation through three tanks. The methodology used for process identification (first-order plus dead time model (FOPDT)) through ClientServer OPC communication with Matlab® is presented. The design of the reinforcement learning algorithm and its adaptation in the learning environment with experimental data are also presented. The simulation results were satisfactory compared to traditional control techniques, demonstrating robustness against forced disturbances. Finally, the implementation of reinforced learning control integrating TIA Portal and Matlab (trough a PLC-S7-1500 controller) was evaluated with a reference of 600 l/h, achieving 0% overshoot with a settling time of 22s. Compared to other control systems, a better response in settling time and overshoot-free control was observed. Finally, perturbations were applied to the system, observing their effect in relation to the flow.

Method for asbestos detection in hyperspectral images based on the approximate components of the wavelet transform and spectral differential similarity
type: item
description: Considering that one of the challenges in material detection within the field of hyperspectral imaging, given its high dimensionality, is the identification of more computationally efficient methods, this article proposes a method for asbestos detection based on the use of the approximate components of the wavelet transform and spectral differential similarity. Variants of the proposed method were implemented using open-source libraries, including Spectral, PyWavelets, NumPy, Pandas, and Matplotlib, achieving similar effectiveness in asbestos detection compared to the correlation-based method. Furthermore, in terms of computational efficiency, it was found that the three variants of the proposed method were more efficient than the correlation-based method, with the method based on the first component of the wavelet transform yielding the best results, being 13.964% more efficient. Based on these results, the variants of the proposed method can be considered as alternatives to conventional methods, allowing them to be integrated into systems for the analysis and monitoring of asbestos and other materials using hyperspectral images. Additionally, this study demonstrated the feasibility of using open-source tools and libraries for material identification in hyperspectral images, making this research a reference point for research centers and universities to replicate and adapt these methods in remote sensing-based investigations.

Multi-agent system focused on distributed artificial intelligence processes for order capture and routing
type: item
description: This paper presents the design of a multi-agent system focused on text-operated distributed artificial intelligence processes that works following a dialog model, oriented to the efficient management of industrial product orders. This system integrates five reasoning and action agents: the general agent powered by Google's Gemini artificial intelligence language model that carries the conversation flow and redirects the tasks to the other agents, an agent that identifies customers, an agent that recognizes the products, an agent that generates the orders and an agent that routes. The multi-agent system is designed to interact virtually and conversationally with users, facilitating order creation and management through an innovative approach that integrates advanced natural language processing technologies, vector and relational databases, and optimization methods. Finally, for its validation in a real environment, data from a company that produces and distributes cleaning products are used, allowing the development of different tests for the identification of customers, products, quantities and the establishment of order delivery routes. It is concluded that the conversational flow and techniques used allow users to make queries about customers with an average accuracy of 77.38% and about products with an average accuracy of 88.57%, even in scenarios with semantic ambiguities, managing orders in an intuitive way. It is also possible to optimize order routing by simultaneously considering two criteria that can be weighted: customer importance and distance traveled.

Design of an electric propulsion system for a subway-type means of transport
type: item
description: This document presents the design of an electric propulsion system for a metro-type transport. For this design, a route was proposed that evaluates the energy demand of passenger mobility in the city of Villavicencio (Colombia). The foregoing allows choosing the technical characteristics necessary to satisfy the quality of the service provided. For this, a mathematical model of the longitudinal dynamics of the vehicle was exposed, which studies the forces of interaction through Gillespie simulation, obtaining relevant information on its behavior compared to its operation, the above is determined by means of a computer simulation. The energy study performs the reading of the altimetry data of the chosen route, together with the inclination angles, through the variation of heights and distances. The simulated simulation executes the different data of the chosen train together with its respective trailer, following the trajectory of the chosen route, in order to quantify the forces, power and energy necessary to carry out the total route.

Inverse kinematics for a 2R planar robot based on a neural network with synthetic data through a model ensemble approach
type: item
description: This article presents the development of a neural network-based model, trained with synthetic data, to replace the geometric inverse kinematics of a 2R planar robot. This approach aims to simplify the implementation of kinematics, reducing development time and computational resource usage. The model was created in Google Colab (Python) using TensorFlow/Keras, which facilitated its creation and training. Furthermore, the system integrates real-time image processing to recognize and follow contours, which the robot subsequently traces. A linear and vertical motion was implemented using a rack-and-pinion mechanism, enabling discontinuous tracing between contours of an image. The results, averaging three neural network models, show high accuracy in predicting the angles of the robot's first two joints, with an RMSE of 0.2293 and 0.0739 compared to the geometric inverse kinematics.

State observer control for robotic series elastic actuators
type: item
description: This implementation shows the results through a control state observer strategy for a series elastic actuator (SEA) of motorized robotic limbs, with the purpose of evaluate the disturbance response with regard to convetional PID controller. By implementing a Matlab® script, the goal was to evaluate the state observer controller for a series elastic actuator space state dynamic model in comparison with a conventional PID controller, verifying the behavior of each by adding disturbances. The advantages of the state observer control strategy with respect to the conventional PID controller could be verified. The state observer ensures that the series elastic actuator is not affected by disturbances, presenting better performance than the PID in SEA control. The Matlab® simulation of the state space dynamic model of the series elastic actuator and its control by a state observer, shows the advantage that it offers in its dynamic response in scenarios with disturbances and eliminates its effect on the process in steady state.

Step Up/Down Rectifier with Power Factor Correction based on a Cuk converter and sliding-mode control
type: item
description: The demand for reactive power from the distribution system and the production of current harmonics due to nonlinear active loads reduce the active power transport capacity, produce electrical losses and alter the voltage in the feeder buses of the distribution network. To face these challenges, this paper presents the design of a step-up/down rectifier and its control system to correct the power factor and mitigate the current harmonics produced by non-linear loads. The power interface is based on a Cuk converter, which enables to supply DC loads with voltages higher or lower than the peak value of the grid voltage. The Cuk converter is connected between the rectifier and the DC load. The main contribution of this work consists in a design method for the Cuk converter and its control system, ensuring specifications of the distribution system, the converter, and the load. The methodology consists of a design procedure of three controllers and the converter from their electrical and mathematical models. The design procedure is validated through two application examples simulated in the PSIM software. The results show the effectiveness of the design in mitigating harmonics, producing a power factor equal to one, maintaining low ripple and regulating the voltage at the load. The results show that the proposed design guarantees a ripple percentage in the grid of 2.5% and in the load of 5%, a power factor practically equal to unity, and voltage regulation in the expected number of cycles.

Evaluation of the transtibial amputee gait using inertial sensors and cyclograms: impact of prosthetic misalignment
type: item
description: Gait in transtibial amputees involves significant biomechanical adaptations due to the absence of the distal segment of the lower limb, leading to alterations in movement patterns. Dynamic alignment of the prosthesis is essential for efficient locomotion but is often adjusted subjectively through clinical observation. This study analyzed the gait of three transtibial amputees using inertial sensors and cyclograms. The TECH-NAID® system, which employs inertial measurement units (IMUs), was used for motion capture, while cyclograms enabled a detailed and objective assessment of joint kinematics. Gait was evaluated under standard alignment and controlled misalignment conditions at the socket (abduction/adduction, flexion/extension) and the prosthetic foot (dorsiflexion/plantarflexion, inversion/eversion), with angular variations of 2°, 6°, and 10°. The results revealed significant alterations in the kinematics of the hip, knee, and ankle joints, as well as compensatory mechanisms between limbs. Cyclograms proved to be effective clinical tools for assessing gait deviations in prosthetic rehabilitation.

A Multi-Modal ViT-Based Deep Learning Architecture for Binary Classification of Traffic Accident
type: item
description: Each year, more than 1 million people die due to traffic accidents, and one-third of these lives could be saved by reducing medical response time. Multi-Modal Deep Learning (MMDL) has emerged in recent years as a powerful tool that integrates different types of data to enhance decision-making capabilities in models. Additionally, Vision Transformers (ViT) are a Deep Learning approach for processing images and videos that has shown promising results in various fields of knowledge. In this project, we propose a ViT-based architecture for binary classification of traffic accidents using data from multiple sources, such as environmental data and images. The integration of an MMDL approach based on ViT can improve the model's accuracy in classifying accidents and non-accidents. This project explores a MMDL approach integrating ViT for traffic accident monitoring in the context of smart cities, achieving a recall of 91%, which evidences a high robustness of the model in identifying positive cases. However, the scarcity of multimodal data represents a major challenge for training these types of models.

Visual Classification Algorithm for Chonto Tomatoes According to Standard NTC-1103-1 (Color, Size and Shape Parameters)
type: item
description: This article introduces the development and implementation a low-cost system for the classification of Chonto tomatoes according to their color, shape and size, in accordance with the Colombian technical standard NTC 1103-1. To achieve the proposed objective, a classification algorithm is developed using Python and OpenCV software. The obtained results show that the classification for color and maturity had an accuracy of 93%. In the classification by size the precision was 98%. Regarding the evaluation of eccentricity for determining the shape, an accuracy of 80% was obtained. The precision values mentioned above are comparisons with the results obtained manually by a trained individual, which are considered the ideal classification. However, the response time of the algorithm is 0.48 sec, in average, which is much less than the time required for human inspection and classification. In addition to precision achieved, it can be said that the developed software responds to the need to detect and classify chonto tomatoes according to their color, size and shape established in the Colombian technical standard NTC 1103- 1.

Comparative technical study of topographic surveys in mountainous areas carried out with total station, GNSS equipment, and non-specialized UAV with and without control point support
type: item
description: This study compares three commonly used topographic technologies for mapping mountainous terrain: total station, GNSS equipment, and non-specialized UAV (with and without control points). The comparison considered chronological and technical criteria to determine the advantages and disadvantages of each technology. The study found that GNSS antennas, when they have optimal satellite reception and communication between the base and rover, offer the best performance compared to the other survey methods. They achieved accuracy similar to that of a total station, with considerably shorter execution times. Another finding was that the data collected with a UAV using control points allowed for a geomorphological description of the area but with significantly lower accuracy than the other technologies. These results emphasize the importance of performing a high densification of control points to achieve greater accuracy, even if it means increasing the required fieldwork time.
