Photovoltaic systems are an important solution to provide electrical energy to isolated loads. Microinverters manage the energy harvested from photovoltaic panels; therefore, to ensure the correct operation of microinverters is essential to extract the energy properly. This paper presents the implementation of an overvoltage protection circuit to secure the passive elements and power switches in microinverters. The overvoltage protector avoids the damage due to high voltage stress on the elements and allows a restarting when the correct operation is guaranteed. Experimental results validate the proper behavior of the proposed system in different situations.

This work presents an analytical method to extract the elements of the asymmetric single-$pi$ electrical equivalent circuit of on-chip inductors. The elements are extracted from linear regression using the y-parameters of the chip inductors. The high correlation of the S-parameters between the model and the measurement of an on-chip inductor manufactured under the 0.5 $mu{mathrm{m}}$ CMOS process and electromagnetic simulation data based on the 0.13 $mu{mathrm{m}}$ CMOS process validates the proposed methodology up to 20 GHz.

Structural Health Monitoring (SHM) is a field in which nodes with low power consumption in a wireless sensor network present clear advantages regarding deployability and maintainability. This work presents a general design proposal for a power-saving strategy for a collaborative network used in SHM. This strategy includes; code profiling recommendations, CPU Load measurements, and voltage-current measurements for an instruction-level optimization approach. This strategy increases the battery autonomy of the network nodes up to 586% with LoRa communication and Dynamic Power Management, considering three hours and 31 minutes as a baseline, achieving up to twenty-three hours and 45 minutes; moreover, it can reduce the mean power utilization by 11.81% in masters devices which for this work are called primary devices and 39.52 % for slaves devices, treated as the secondary ones. Furthermore, some significant results for CPU utilization reduction are presented, as well as identifying some areas of interest for future improvements.

This work proposes using a control system for the operation of a Minigrid System composed of two types of sources: an Inverter Based Resource (IBR) and a Synchronous Generator. The system uses a very efficient Digital Genset Controller that optimizes the performance of the Minigrid, which can operate in island mode or connected to the external grid. NEPLAN Web Services are also used in the SCADA system for the implementation of the power management system based on the optimal power flow solution. The overall work was implemented in a laboratory with real technologies in generation, control, communication, and load.

This document describes the development of a STEM course intended to improve the Computational Thinking of university students (CT). The main instructional tool for this course is the BEAM robot, a robotics paradigm that proposes simple robots whose behavior can be controlled without software programming. The programming of this robot is implicit in its morphology, so its actions and goals are codified from its construction. A three-phase curriculum is designed to achieve the objective: propaedeutic, robot assembly, and CT. On the basis of these phases, the course is constructed modularly and implemented virtually, while students receive construction kits. Each phase aims to foster the many facets of CT, such as decomposition, abstraction, algorithm, debugging, iteration, and generalization. Students’ responses to pre-and post-course surveys, as well as evaluation activities and logs, are analyzed to determine the course’s impact on them. In addition to other STEM disciplines (electrical, electronic, mechanical, and WEEE), the course substantially improves the CT.

On october 1th, 2021, international outlets reported El Salvador had just started mining Bitcoin using energy from volcanoes. CNBC published that “El Salvador had mined 0.0059918 Bitcoin, or about US${$}$269.00 at the time, with power harnessed from a volcano”. Just three months before, president Nayib Bukele had instructed state-owned geothermal electric company, LaGeo S.A. de C.V., to “put up a plan to offer facilities for Bitcoin mining with very cheap, 100% clean, 100% renewable, 0 emissions energy from our volcanoes.” But how true it was to put up a geothermal electric power plant in three months? Was it profitable to mine Bitcoin from a geothermal source? This has not been the kind of transparent government, information has been hard to acquire. However its need for publicity and its desire to appear as a technology savvy government made them show some details of their mining operation. An early analysis has shown up there was no new power plant nor profit on mining crypto. Bitcoin mining bet appears to be backfiring, showing the gap between false promises of producing crypto money and economic realities.
2021年10月1日，国际媒体报道称，萨尔瓦多刚刚开始使用火山能源开采比特币。美国全国广播公司财经频道(CNBC)报道称，“萨尔瓦多利用火山的电力开采了0.0059918个比特币，当时约为269.00美元。”就在三个月前，总统纳伊布·布克莱(Nayib Bukele)指示国有地热电力公司LaGeo S.A. de c.v.“制定一项计划，为比特币挖矿提供非常便宜、100%清洁、100%可再生、零排放的火山能源。”但是在三个月内建一个地热发电厂是真的吗?从地热资源中开采比特币有利可图吗?这不是一个透明的政府，信息很难获取。然而，由于政府需要宣传，并希望成为一个精通技术的政府，因此他们展示了一些采矿作业的细节。早期的分析显示，挖矿没有新的发电厂，也没有利润。比特币挖矿的赌注似乎适得其反，显示出生产加密货币的虚假承诺与经济现实之间的差距。

In development economics of many countries, banana has been thought of as a key factor, however, banana trees suffer from susceptible to the main climatic conditions such as temperature, humidity, or solar radiation, resulting in a decrease in canopy and leaf area, which has an impact in bunch size and quality. In recent years, teledetection has emerged as a method to analyze the state of the plantation, where multispectral images captured by Unmanned Aerial Vehicle (UAV) are the main information source. This study set out to canopy extraction and estimation of a banana plantation from multispectral images taken at 35 meters height, which are transformed to HSV color field by red-edge band reflectance (REG) and near infrared (NIR). This allowed segmentation to separate the canopy from objects such as dry leaves, ground, and other elements. Finally, the results were compared with manual technique, resulting the proposed methodology has a significant accuracy and adjustment in the results..

There is a considerable number of visually impaired people in the world, who live their daily lives with limitations in their mobility due to the little information they have about their environment. This project proposes to use embedded systems to develop an assistance system for the blind, which, through machine learning models, describes the objects closest to the user and if they are known or unknown. To do this, two trained Machine Learning models will be used, the first to detect common objects and the second to identify particular objects. The intention of using both networks is to improve the accuracy of the system, by first detecting objects or people in an image and then classifying them with known labels (names or some identifier). The results obtained show the benefit of using these neural networks for the recognition of objects in the environment from a general database and then with a personalized one. Finally, to indicate the identified objects to blind people, the text of their labels is translated into speech.

Due to the growth of solar photovoltaic installations around the world, it is necessary to calculate the amount of CO2 avoided or emitted by this technology when installed in Costa Rica. For that reason, the present study intends to compute greenhouse gas emissions payback time (GPBT) in three distinct locations of Costa Rica. The energy consumed along the life cycle of a solar photovoltaic power plant was analyzed, and through the energy payback time and several assumptions, it is intended to visualize the most likely scenario, total amount of emissions was accounted for a simulated 1 MWp AC power plant, using solar panels manufactured in 2017, and total amount of avoided emissions were determined for the operation period of the same plant. The studied scenarios show there is not enough CO2 avoidance in 25 years (from 201S to 2042) of operation to recover emissions from the rest of the life cycle, which means that introducing PV plants in Costa Rican electric matrix will not necessarily avoid emissions.
