The issue of failed weaning is a critical concern in the intensive care unit (ICU) setting. This scenario occurs when a patient experiences difficulty maintaining spontaneous breathing and ensuring a patent airway within the first 48 hours after the withdrawal of mechanical ventilation. Approximately 20 of ICU patients experience this phenomenon, w...

According to the World Health Organization (WHO), pneumonia is a disease that causes a significant number of deaths each year. In response to this issue, the development of a decision support system for the classification of patients into those without pneumonia and those with viral or bacterial pneumonia is proposed. This is achieved by implementi...
Spontaneous breathing trials (SBTs) represent a pivotal phase in the weaning process of mechanically ventilated patients. The objective of these trials is to assess patients readiness to resume independent breathing, thereby facilitating timely weaning and reducing the duration of mechanical ventilation (MV). Nevertheless, accurately predicting the...
The process of weaning from mechanical ventilation is one of the challenges in intensive care units. 66 patients under extubation process (T-tube test) were studied: 33 patients with successful trials and 33 patients who failed to maintain spontaneous breathing and were reconnected. Each patient was characterized using 7 time series from respirator...

Predicting the future weight of an artificial beehive is fundamental to determine the status and production of an artificial bee beehive, the more weight the beehive has at harvest times the more productive it will be, whether the weight was increased by honey, propolis, royal jelly or brood. This paper presents a bidirectional algorithm (Bi-LSTM)...
This paper presents the prediction of poultry growth in relation to the environmental variables that most influence this process using LSTM networks. This required the installation of sensors in a warehouse of the company Nutravi located in Meta, to obtain real-time data on temperature, humidity, wind speed and weight of the chickens, where these m...
The optimal extubating moment is still a challenge in clinical practice. Respiratory pattern variability analysis in patients assisted through mechanical ventilation to identify this optimal moment could contribute to this process. This work proposes the analysis of this variability using several time series obtained from the respiratory flow and e...
The paper presents an object tracking algorithm implemented through an unmanned aerial vehicle (UAV). The system generates the trajectory taking into account the image obtained by the front camera of the drone, the object to be detected is a moving red box and using color segmentation techniques the object is detected. The red box is continuously t...
Weaning from mechanical ventilation in the intensive care unit is a complex and relevant clinical problem. Prolonged mechanical ventilation leads to a variety of medical complications that increase hospital stay and costs, in addition to contributing the morbidity and mortality, affecting long-term quality of life. This work presents a methodology...
Emerson DeltaV is a distributed control system (DCS) that works in a decentralized way and offers hardware and software for large applications and advanced control in the industrial sector. Currently, Emerson is targeting each system to specific industries, such as the oil, chemical, food, beverage, and pharmaceutical industries. This paper present...
The drones are devices of high technology that work thanks to the rotors that allow them to remain and to be propelled in the air. Their movements are controlled by adjusting the propulsion of each propeller and this is done with a device called a flight controller. The paper presents two control system for a UAV-Tricopter. The control techniques p...
This paper proposes an analysis and detection of diabetic retinopathy by using artificial vision technics, such as filtering, transforms, edge detection and segmentation on color fundus images to recognize and categorize microaneurysm, hemorrhages and exudates. The algorithms were validated with the DIARETDB database. Of the processed images are de...
Resumen-La ventilación mecánica (VM) es una estra-tegia terapéutica que consiste en asistir o reemplazar mecánicamente la ventilación pulmonar espontánea. Con el objetivo de desarrollar un software de apoyo para los médicos, se realizó un estudio de las señales respi-ratorias, utilizando la transformada de wavelet discreta, para determinar los desc...
In this work, the cardiorespiratory pattern of patients undergoing extubation process is studied. First, the respiratory and cardiac signals were resampled, next the Symbolic Dynamics (SD) technique was implemented, followed of a dimensionality reduction applying Forward Selection (FS) and Moving Window with Variance Analysis (MWVA) methods. Finall...
