This article is the product of the investigation "Development of a photovoltaic pilot system for performance assessment of isolated systems in the Renewable Energy Laboratory at UNAB" developed at the Universidad Autónoma de Bucaramanga (UNAB) in 2019, considering off-grid solar home systems (SHS) are a feasible alternative in rural remote areas, where access to electric power is limited due to their power grid lack. The objective is to develop a PV test system for off-grid solar home system (SHS) performance assessment. For the development, a case study is analyzed based on the behavior of a user's daily demand in Hato Corozal, Casanare. Design aspects of the system are also elaborated. Key performance parameters identified to be monitored are solar irradiance, power generation, energy consumption and battery charge status. Two scenarios of daily demand behavior are analyzed to evaluate the influence of load shifting on the performance of the system. The applied design criteria were validated obtaining that the sized system satisfied the energy requirement without a battery’s depth of discharge (DOD) deeper than specified, showing the capacity of the system to make studies in longer periods with the possibility of generating different demand behavior scenarios. The designed system presents a performance ratio of 0,77 when a daily consumption is considered, while when shifting loads to coincide them with the higher irradiance the PR was 0,95. In both cases, the SoC was higher than 79%, maintaining a DOD of the battery bank according to the specified in the sizing. The system presents excess energy that can be used by expanding the capacity of the battery bank. Findings suggest that a higher performance ratio is obtained when coinciding consumption peaks with the hours of higher solar radiation.

Summary. Introduction: The article is the product of the research “Technological transition IPv4 - IPv6 protocol" developed at the Francisco José de Caldas District University in 2020. Problem: There is no detailed plan for the transition to IPv6 for the SNR that solves the support and connectivity problems of new devices to compete more efficiently in the telecommunications market for access to officials and the population. Objective: To Generate a transition process plan that includes a detailed description of the phases and includes the key activities for said transition. Methodology: This article, therefore, describes the research and implementation project that led to determine activities, phases and products corresponding to the technological transition from IPv4 to IPv6 in the SNR. Results: The scope is visualized, as well as the documentary assurance through actions and recommendations of the change. Conclusion: It is evident that, after complying with a proposed evaluation methodology, the experience can be characterized as a case of success, since it facilitated the pertinent decision making within the process of adopting the new protocol. Originality: Through this research, the three transition phases suggested by the Ministry of Information Technologies and Communications (MinTIC) are contemplated. Limitations: The technological transition from the IPv4 to IPv6 protocol is limited to the fact that the process is not immediate but transitory, so it must be supported by transition mechanisms that allow the coexistence of both protocols.

Introduction: This paper is the result of the research “Design and control of single phase voltage compensator based on AC Chopper” developed in the AD-AF Academy of Viet Nam in 2019. Problem: This article develops power electronic devices based on AC chopper and provides solution for the voltage sag which is long-lasting and deep amplitude of fading at rural power grid. Objective: Improve the quality of the electricity system in rural Vietnam. Methodology: With the improvement of power system, power quality has become the major concern of user and grid companies. The Voltage sag has turned into the research priority because of the most frequently happening and great economic loss. Based on the rounded analysis of traditional voltage compensation devices, this article develops power electronic devices based on AC chopper and provides solution for the voltage sag which is long-lasting and deep amplitude of fading at rural power grid. Results: On the one hand, it reduces the cost and space of the device. On the other hand, it solves the short compensation time of UPS and DVR. Conclusion: The trial operation proves that this single-phase low-voltage compensation device has obvious compensation effect for most resistive loads and some inductive loads, less harmonic content, long continuous compensation time and stable performance. Originality: This compensation device integrates the advantages of UPS and DVR, and also solves their shortcomings and deficiencies. Limitations: The authors need to spend more time to the development and design three-phase low-voltage compensation device.

Introduction: This article is the result of research entitled “Signal processing system for the detection of people in agglomerations in areas of public space in the city of Cúcuta”, developed at the Universidad Francisco de Paula Santander in 2020.Problem: The high percentage of false positives and false negatives in people detection processes makes decision making in video surveillance, tracking and tracing applications complex. Objective: To determine which technique for the detection of people presents better results in terms of respon-se time and detection hits.Methodology: Two techniques for the detection of people in uncontrolled environments are validated in Python with videos taken inside the Universidad Francisco de Paula Santander: Background subtraction and the YOLO algorithm.Results: With the background subtraction technique, we obtained a hit rate of 84.07 % and an average response time of 0.815 seconds. Likewise, with the YOLO algorithm the hit rate and average response time are 90% and 4.59 seconds respectively.Conclusion: It is possible to infer the use of the background subtraction technique in hardware tools such as the Pi 3B+ Raspberry board for processes in which the analysis of information in real time is prioritized, while the YOLO algorithm presents the characteristics required in the processes in which the information is analyzed after the acquisition of the image.Originality: Through this research, aspects required for the real-time analysis of information obtained in pro-cesses of people detection in uncontrolled environments were analyzed. Limitations: The analyzed videos were taken only at the Universidad Francisco de Paula Santander. Also, the Raspberry Pi 3B+ board overheats when processing the video images, due to the full resource requirement of the device.

This literature review article is a product of the Research Project “Relation Between Climate Variability with Mass Removal Processes. Tunja-Páez case study”, developed in the Universidad Pedagógica y Tecnológica de Colombia in the year 2020. Introduction: This article focuses on the review of research studies and advances made during the last decade regarding the influence of climatic variability on the dynamics of slopes. Objective: To determine the influence of climatic variability in areas that present slope instability in the Tunja-Páez road corridor located in the department of Boyacá. Methods: A systematic review of information from books, manuals, reports, guides, and scientific articles on climate change, climate variability, mass removal processes, meteorological variables, and their influence on the resilience and adaptation of infrastructure related to containment and slope drainage projects. Results: The studies indicate criteria that relate temperature, precipitation and seismic activity with the occurrence of mass movements. Conclusion: Climatic anomalies in terms of precipitation and temperature has allowed research methodologies using probabilistic models to be developed for estimating the occurrence of said phenomena in future scenarios. Originality: The presented literature indicates the influence of climatic variability in the resulting mass removal processes as evidenced in studies at the global and national level. Limitations: This article scientific studies have been compiled that contrast the problems in the stability of slopes of the Tunja-Páez road corridor, without going into the details of these problems.

Most of the beat-tracking research tends to work on the exploration of theoretical strategies and not on the development of automatic devices that can be functional in real musical environments. As a consequence of the above, there is a scarcity of electronic devices for musical backing based on the beat-tracking technique. So, we have developed an automatic musical backing device based on beat-tracking with the real-time operation.
