The sizing of a solar thermal system to feed the water distillers in the laboratory of the Santander Technological Units is presented, proposing a comparative study between three calculation methods (f-chart, instantaneous and ACSOL) for the estimation of the surface of solar capture, finally supported by modeling in the TRNSYS software of the final system, to evaluate its behavior dynamically during one year. Initially, a search for information is carried out to establish the models to develop each of the calculation methods, additionally technical data is collected from the laboratory equipment to determine the consumption of hot water. Subsequently, each of the calculation methods is applied in order to size the catchment surface, to finally carry out a comparative study between the results obtained, determining which is the most appropriate method for the calculation and defining the dimensions of the same, to develop a modeling of the dynamic behavior of the system through the TRNSYS Software. The final result presents a storage system with an average temperature of 62.13 ° C and solar collectors with an average temperature of 58.7 ° C for one year of operation. Finally, the operating time of the resistive stills is reduced from 11 hours a day to 6 hours with the integration of the Thermosolar system.

The research focuses on the evaluation of the progress of the renewable installed capacity of the meridian countries with Colombia. Junto a Colombia, there are 12 other countries that are crossed by an imaginary line that surrounds the planet and because of this, each of these countries that it crosses, have a similar climatology, which, compared to Colombia, is assimilated to have the same conditions for the implementation of renewable energies. A bibliographic compilation was carried out where the amount of published information that can show the moment that the energy sector of each country that belongs to the Equatorial Meridian is going through was taken into account, with the aim of analyzing and comparing the energy news of Colombia with respect to these. This study shows the current energy state of each country, where different points are observed in relation to renewable and conventional energies. This comparative analysis was carried out based on the information found and gives a good impression of Colombia in the current and future energy field, but with difficulties due to factors outside its projection.

This paper evaluates the technological trends in the carbon sequestration process. For this purpose, these systems have been classified into two subsystems: conventional technologies subsystem and emerging technologies subsystem. Each is explored for its suitability for meeting a set of six attributes. A bibliometric analysis process was developed using the Scopus database and VOSviewer Software to present the potential of each subsystem evaluated, through an evaluation matrix. The analysis of the subsystems and attributes was performed through the formal concept analysis methodology (8FCA). To facilitate the processing of the information, the open access software concept Explorer was used. The analysis shows that conventional technologies, despite their cost, will be maintained and advance in their implementation process. The bibliometric analysis integrated with the applied FCA methodology has proven to be useful for the evaluation of technological typologies and serves as an alternative to develop theoretical studies that group and link different options as a model to evaluate a deterministic set of attributes.

This paper evaluates the applicability of centralized concentrating solar power systems in Colombia. For this purpose, these systems have been classified into four subsystems: parabolic trough, linear Fresnel, parabolic dish and tower. Each is explored for its suitability by meeting a set of six attributes. A bibliometric analysis process was developed using the Scopus database and the VOSviewer software to present the potential of each subsystem evaluated through an evaluation matrix. The analysis of the subsystems and attributes was carried out through the formal concept analysis methodology 8FCA). To facilitate data processing, the open access software concept Explorer is implemented. The analysis shows that parabolic trough technology is more widely used worldwide than the other three technologies evaluated, and its maturity makes it possible to plan centralized and decentralized projects in developing countries. The bibliometric analysis integrated with the applied FCA methodology has proven to be useful for the evaluation of technological typologies and serves as an alternative to develop theoretical studies that group and link different options as a model to evaluate a deterministic set of attributes.

An algorithm of automatic learning was developed. That is abke to identify radiographic images with a pneumonia and not pneumonia diagnose based on a data set published in the “Kaggle” platform by the Radiological Society of North America, from which we obtained a set of specific images with their labels that were divided by 70% to train a convolutional neuronal network model consisting of two convolutional layers for the extraction of characteristics in each image, and ends with a classification stage in the training of the model, to conclude with 74% in metrics of accuracy given by test tests with 30% of the data set.

It is known that global warming and the carbon footprint are directly proportional, that is, the more carbon footprint there is, the more global warming there will be, for this reason it was decided to take this environmental problem and calculate the carbon footprint of the engineering faculty of the Sinú University, in this way, the university can know the CO2 emission that is emitted in the faculty and in this way be able to take actions regarding the mitigation of these emissions. For this, a mobile application was developed with the Dart development language, this application can perform manual calculations of the carbon footprint, and a real-time calculation was implemented through a sensor that is connected to an Arduino, this Sensor can measure the electrical flow of a device and sends the information to an IoT server. Knowing the electric flux, the carbon footprint can be calculated. The application allows to control emissions, and organizes this information by means of graphs, and in this way the user can have a better understanding of the stored information.

This research presents a comprehensive experimental study on the effect of temperature, material and process parameters related to tensile strength response in 3D printing manufacturing process with ABS material. A Hyper Latin Square design was chosen for the experimental points distribution. Thirteen parameters with multiple levels are considered LAYERHEIGHT, WALLTHICKNESS, TOPBOTTOMTHICKNESS, TOPBOTTOM-LINEDIRECTION1, TOPBOTTOMLINEDIRECTION2, INFILLDENSITY, INFILLLINEDI-RECTION1, INFILLLINEDIRECTION2, PRINTSPEED, EXTRUSIONTEMP, BEDTEMP, WORKSPACETEMP and POSITION. Type IV tensile specimens are fabricated and tested with an universal testing machine. Maximum stress is measured, evaluated and analyzed in three different building positions.Machine learning algorithm with Orange Data mining software are used to study underlying relations between factors and response. Experimental results indicate that INFILLDENSITY, TOPBOTTOMTHICKNESS and INFILLLINEDIRECTION1 has a strong positive correlation with tensile strength. Meanwhile, TOPBOTTOMLINEDI-RECTION1, WORKSPACETEMPERATURE and PRINTSPEED has a negative correlation with tensile strength. Position 1 with line depositions parallel to Y axis produce the higher tensile strength response. Findings imply that machine algorithms can be used to study multiple parameters at time.
本研究对 ABS 材料 3D 打印制造过程中与拉伸强度响应相关的温度、材料和工艺参数的影响进行了全面的实验研究。实验点分布采用超拉丁方阵设计。考虑了 13 个多级参数：层高（LAYERHEIGHT）、壁厚（WALLTHICKNESS）、顶底板厚度（TOPBOTTOMTHICKNESS）、顶底板连线方向1（TOPBOTTOM-LINEDIRECTION1）、顶底板连线方向2（TOPBOTTOM-LINEDIRECTION2）、渗透密度（INFILLDENSITY）、渗透连线方向1（INFILLLINEDI-RECTION1）、渗透连线方向2（INFILLLINEDIRECTION2）、打印速度（PRINTSPEED）、挤压速度（EXTRUSIONTEMP）、基底速度（BEDTEMP）、工作空间速度（WORKSPACETEMP）和位置（POSITION）。用万能试验机制作和测试 IV 型拉伸试样。使用 Orange 数据挖掘软件的机器学习算法来研究因素与响应之间的潜在关系。实验结果表明，INFILLDENSITY、TOPBOTTOMTHICKNESS 和 INFILLLINEDIRECTION1 与抗拉强度有很强的正相关性。同时，顶面线性方向 1、工作空间温度和印花速度与抗拉强度呈负相关。位置 1 的线条沉积平行于 Y 轴，产生的抗拉强度响应较高。研究结果表明，机器算法可用于同时研究多个参数。
