Introduction: This article is the product of the research “Study of the IPv6 Protocol in the data model of the Smart Grid distribution domain” developed at the Universidad del Valle and carried out during 2019. Problem: There is an immediate need to establish standards and protocols for the Smart Grid for both the electrical components and the component technologies of information and communication. Objective: The objective of the research is to characterize the use of IPv6 in the context of the communications domain distribution of the Smart Grid. Methodology: The work defines a virtualization environment in which the performance of IPv6 in the domain distribution of the Smart Grid will be evaluated; this evaluation includes measurement and analysis of delays as well as traffic volumes, bandwidth, cyber-security conditions, and time allocation of network addresses. Results: The IPv6 protocol is considered as a viable alternative in the Smart Grid communication model in order to comply with the communication requirements. Conclusion: The implementation of Quality of Service QoS in IPv6 defined in RFC2474 is essential in the Smart Grid communication network in order to meet the communication requirements of the defined applications. Originality: There is great expectation that networks based on the Internet Protocol will serve as a key element for communications within the Smart Grid. Limitations: The wide scope and dimensions involving Smart Grids, it is almost impossible to implement the communication network of a Smart Grid completely in a single simulation tool or emulation.

Introduction: This contribution is about a low-cost microwave reactor for green synthesis of nanomaterials. The paper reflects research results achieved at the NanoFab group of the Universidad Militar Nueva Granada, within the line of nanophotonics, sensors and nanotechnology. Investigations and analyses were carried out during 2019. Problem: Conventional synthesis processes usually affect the environment and human health, due to contaminant reagents and generation of by-products. Objective: The aim of this research is the modification of a microwave oven that assists in the green synthesis of nanomaterials with potential applications in homeland security. Methodology: In this investigation, the modification of a domestic microwave was carried out. The implemented reactor features a heat exchange unit to reduce volatile elements, and a digital magnetic stirrer for local homogenization. Synthesis begins with a trisodium-citrate solution, continuously stirred at 37 °C. Next, the precursor is mixed with silver-nitrate for 2 minutes. Then, the mixture was treated for 20 minutes in the microwave reactor. Finally, the nanoparticles are recovered. Results: The homemade microwave reactor is suitable for producing nanoparticles. Particularly, the 20-minute microwave exposure time for the reactants results in a nanoparticle size between 80-90 nm. To probe reaction parameters, impedance spectroscopy analysis is performed. Results revealed that the resistance of the medium of silver nanoparticles is 2.5 ohms, while for sodium citrate and nitrate it is 8.8 and 11.8 ohms, respectively. Conclusion: It is demonstrated that the modified microwave reactor is suitable for nanomaterial production. Lower amounts of solvent are required during nanoparticle synthesis. Microwave synthesis allows for green nanomaterials production with a minor impact on the environment. Limitation: Homogeneous heating of reactants in a stationary microwave cavity is limited to waveguide design; in this case, to a multimodal-microwave waveguide. Originality: Low-cost reactor for nanomaterial production and greener synthesis.

Objective: To evaluate the Electro-Fenton strategy as an alternative for the treatment of wastewater from the skin tanning process. Methodology: An experimental design of factorial type 33 is used in two phases, utilizing a Batch type reactor, in the first phase the number of iron electrodes, H2O2 dosage and current intensity supplied is analyzed. For the second phase, the reaction time is varied, with a number of plates defined the parameters of sulfide concentration, total organic carbon (TOC) and both initial and final turbidity for a subsequent analysis of variance (ANOVA) were analyzed. Conclusion: In the first stage of treatment for a reaction time of 60 minutes a turbidity removal of 96.2%, 65.4% sulfide and 52.3% of TOC was obtained, with these it was determined that with 4 electrodes the greatest removal was obtained. In the second stage with follow-up treatment in function of time, a removal of 99.2% for turbidity, 68.35% for sulfur and 53.5% for TOC was obtained. Originality: An electrochemical system is used to treat wastewater from the tannery industry, based on previous research, in order to adapt the technology to the sector mentioned initially. Limitations: The study is limited to the use of iron electrodes, current densities and doses of H2O2 used, in this type of systems aluminum electrodes, stainless steel, graphite and doped materials can be used to maximize the reaction in the electrodes, as well as the use of ozone as an oxidizing agent.

Introduction: This article is the result of the research project entitled “Mobile classroom for military tactical training in cavalry mission planning, development in the Cavalry school of the Colombian Army from 2010 to 2017”. Its purpose is to identify tools to improve the training process of military personnel. Problem: The training is carried out in a theoretical environment as there is currently no alternative means to training personnel in this field. The present investigation aims to improve the instruction of the army personal with their varying roles and ranks –officers, non-commissioned officers (NCOs) and enlisted soldiers–, when encountering individual and collective training. Objective: Evaluate the impact of the implementation of a mobile classroom equipped with simulation tools, as a strategy for the formation of the members of the Cavalry School. Methodology: Empirical study developed in 5 stages: (i) initial instruction, (ii) diagnostic test, (iii) diagnostic feedback, (iv) performance test and (v) performance evaluation. For this, the adaptation of a trailer, such as a mobile classroom, and the ARMA 3 game was used. Results: The use of the mobile classroom allowed for an increase in the number of trained people whilst reduced training times resulting in lower operating costs and greater sustainability. Conclusion: The implementation of the mobile classroom and the simulation system contributed to the development of skills and abilities, improved decision-making capacities, increased perceptual variation and improved coordination, communication and team decision-making. Originality: First mobile classroom for military training, with invention patent, 10-61804. Limitation: The investigation was carried out at the Cavalry School. The results can only be replicable in other military study centers.

Introduction: This publication is the product of research developed within the research lines of the Smart Sensing, Signal Processing, and Applications (3SPA) research group throughout 2018, which supports the work of a doctor’s degree at VNU University of Engineering & Technology, Vietnam. Problem: The limitations of diagnostic ultrasound techniques using echo information has motivated the study of new imaging models in order to create additional quantitative ultrasound information in multi-model imaging devices. A promising solution is to use image sound contrast because it is capable of detecting changes in diseased tissue structures. Ultrasound tomography shows speed-of-sound changes in the propagation medium of sound waves. This technique is primarily used for imaging cancer-causing cells in womens’ breasts. The Distorted Born Iterative Method (DBIM), based on the first-order Born approximation, is an efficient diffraction tomography approach. The compressed sensing technique is utilized for DBIM to obtain the high-quality ultrasound image, although the image reconstruction process is quite long. Objective: The objective of the research is to propose an combined method for the efficient ultrasound tomography. Methodology: In this paper, we proposed an approach to enhance the imaging quality and to reduce the imaging time by applying the compressed sensing technique along with the multi-resolution technique for the DBIM. Results: The simulation results indicate that the imaging time is reduced by 33% and the imaging quality is improved by 83%. Conclusion: This project seeks to propose an improvement in ultrasound tomography. The simulated results confirmed the realibility of the propsed method. Originality: Through this research, a combined method of compressed sensing and multiple resolution are formulated for the first time in ultrasound tomography. Limitations: The lack of experiments to confirm the proposed method.

Introduction: Machine Learning arises as one of the techniques of artificial intelligence, with the development of computer programs that, through algorithms, access data and use them to learn and predict results. Their application in education allows for the characterization of problems or difficulties in learning through the analysis of student performance. Objective: Identification of applications of Machine Learning that can be applied to the educational field accompanied by a proposal of architecture for the application in an environment of personalized education. Methodology: This article begins with the review of the literature on the characteristics of Machine Learning and academic desertion, with an emphasis on the Colombian case, the Hyper-personalization and its applicability to learning methodologies. Then, a proposal of architecture in a Machine Learning environment is generated in order to mitigate the academic desertion caused by academic factors. Finally, we propose mechanisms for evaluating the proposed architecture, with a subsequent synthesis and discussion of the results. Conclusions: The construction of a Moodle architecture for the hyper-personalization of learning, is a global perspective of the representative factors proposed for the development of applications through Machine Learning. This could lead to a decrease in levels of university academic desertion because it facilitates the management of knowledge, information and adaptation through the analysis of scenarios. Originality: The proposed architecture is shown as an application of machine learning in social cases such as academic desertion, allowing the inclusion of automatic learning models with the requirements of an educational environment. Restrictions: The case for the application for the Hyper-personalization of learning uses an academic approach which can generate invalid results regarding desertion levels.

Introduction: This publication is the product of research entitled “Production of Bioethanol from Bore” developed in the year 2016 at the National University of Colombia in Medellín, Colombia. Objective: To reduce the emissions of gases produced by the combustion of petrol by use of a 90:10 fuel-ethanol mixture from the bioethanol obtained from the Bore plant (Alocasia macrorrhiza). Methodology: The process for obtaining ethanol involves pretreatment of the raw material through washing and husking, liquefied, pre-drying, pre-shredding, drying, crushing and sifting and later a microbial fermentation using the Yeast Saccharomyces cerevisiae. Conclusions: The admixtures of bioethanol in 90:10 fuel-bioethanol mixtures generated an increase in the quality of the fuel, due to the oxygen present in the mixture which improves the combustion. Following this work, it is concluded that Bore (Alocasia macrorrhiza) is a promising raw material in the production of a bioethanol with the highest concentrations of starch and better results from fermentation with Saccharomyces cerevisiae. Originality: To provide a new unknown raw material to produce a bioethanol destined for mixtures with gasoline. Limitations: The general lack of knowledge of the plant, commonly called a weed, in addition to few references related to its use in the production of bioethanol.

Introduction: This article presents a review and analysis of studies that concern research made into “Road infrastructure design models to improve road safety for vulnerable users, prioritizing the high accident zones in Bogota D.C.” Objective: To understand the interrelationship between the vulnerable road users, natural surrounding factors and buildings, based on the determination of the most representative variables for the analysis using Geographic Information Systems (GIS), applied to the prioritization of areas with high accident rates. Methodology: It is based on identifying, through review, the known and unknown updated and important results about accident investigations with regards to vulnerable road users. Results: The use of multivariable correlation – analysis of groupings that are treated with GIS – to identify the main factors associated with the seriousness of traffic accidents related to vulnerable road users, allows for the generation of road infrastructure designs that reduce the risk, based on areas of high frequency of occurrence. Conclusions: The multi-criteria analysis and Geographic Information Systems (GIS), allow for the prioritization of areas with high accident rates not only through the evaluation of the quantity of accidents but also by the evaluation of their conditions, by which causal factors of greater influence are identified. Originality: Development of infrastructure plans that reduce the risk of vulnerable road users being struck by a vehicle. Limitations: The methodology is only applied to urban areas where there is a pre-existing history of accidents.
