Brazil is a big consumer of liquefied natural gas (LNG), while Morocco is a big fossil fuel importer. This dependence not only entails substantial import costs for Morocco and high NG liquefaction and transportation expenses for Brazil, but also contributes to elevated carbon emissions. Consequently, Brazil and Morocco are actively exploring substitute resources of renewable power to decrease their dependence on natural fuels and align with global renewable energy targets, including those set forth in agreements like the Kyoto Protocol. Brazil and Morocco boast an abundant array of renewable energy resources, including wind, hydro, solar, and biomass. Leveraging these resources has the potential to swiftly propel these countries towards a low-carbon emissions status when harnessed sustainably for electric power generation. Instead of relying on fossil fuels, the focus of this study is on tapping into the significant potential for power and electricity generation from agricultural residues in Morocco, giving the lessons to Brazilian energy sector for power and electric energy generation form ample agricultural biomass within Brazil. The results show a high potential for energy and electricity generation from cereals, olive biomass, citrus, and date palm residues in Morocco, while cereals, citrus, and sugarcane have better potential for bioenergy and electricity generation in Brazil.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"22 11","pages":"952-961"},"PeriodicalIF":1.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10735448","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a protection for DC systems based on transient di/dt detection is proposed to provide faster short-circuit and overcurrent fault detection, where DC breakers are required to be designed for bidirectional fault current conditions, which is a challenge regarding DC microgrid applications due to some associated problems such as long periods of fault interruption, complex circuit structure, and low reliability. The proposal can detect fault current conditions for different distances from the point of failure, and is suitable to operation in both islanding and grid connected conditions. The proposed circuit was analyzed theoretically and experimentally in steady state, as well as under load changes and short circuit conditions to ensure proper operation, making this solution a suitable fast current fault DC breaker solution, which is a significant advantage and requirement in protection of DC systems.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"22 11","pages":"945-951"},"PeriodicalIF":1.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10735447","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paraguay and Morocco are noted to derive the greater share of their energy from fossil fuel imports. However, the high import bills and carbon emissions, as well as the depleting nature of fossil resources have compelled these countries to seek sustainable power sources. Bioenergy from agricultural residues is an example of such sources due to the high agricultural production in Paraguay and Morocco. Therefore, in this study, the potential of electric energy generation from the biomass of three different varieties of Bertoni namely; Gawi, SugHigh3, and Pop in rural regions of Morocco has been analyzed. The analysis showed that the capacity of the electricity generation from stevia biomass for the different regions considered in the study ranged from 421.2 to 16865 W/ha, while the leaf yield and HHV variation for the different varieties ranged between 2.15 t/ha and 7.86 t/ha, and 21.24 MJ/kg and 27.83 MJ/kg, respectively. By considering a 1.66-kW biogas generator with operating hours of 8761 per year and LHV of 26.436 MJ/kg, as well as gasification ratio of 0.7 and 63.1% carbon content for HOMER simulation, a total capacity of 6.64 MW is suggested for installation in Tazuta. The findings indicate that Bertonis dry leaves are excellent biomass resources for energy production in rural regions of Berkane, Larache, Marrakech, Rabat, and Sefrou and they can give us good lessons for rural electrification of Paraguay.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"22 11","pages":"911-919"},"PeriodicalIF":1.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10735445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This topology shows the enhancement in the steady-state performance by reducing flux and torque ripples and minimizing the percentage of total harmonic distortion (%THD) in stator current. The FCS-MPTC scheme proposed here employs a shared DC link for both inverters, ensuring zero common mode current, thereby eliminating the need for a large isolation transformer. This topology generates Synthetic voltage vectors (SVV) which result from the vector summation of the individual inverter virtual voltage vectors. Common Mode Voltage (CMV) across the motor windings is nullified using this topology. Another notable aspect of FCS-MPTC is its ability to suppress high harmonic currents through the windings by reducing the average voltage in the non-torque-producing plane (x-y plane).

The country produces two main types of ethanol: i) hydrous ethanol, directly utilized as vehicle fuel, and ii) anhydrous ethanol, presently integrated at a rate of 27% into regular gasoline. In 2023, data from the National Agency of Petroleum, Natural Gas, and Biofuels (ANP) indicated that the total volume of ethanol sold in Brazil (hydrous and anhydrous) was just over 28 million cubic meters (m3), which corresponded to almost 22% of the total volume of liquid fuels sold in the country. These numbers illustrate the importance of this biofuel in Brazil. Just six states account for approximately 90% of Brazilian ethanol production. The logistical challenge arises from production seasonality and the necessity to transport ethanol from production sites to distribution and resale networks. Commonly, such prediction is supported using econometric models, such as ARIMA. Considering the recent advances in Artificial Intelligence, this challenge prompts the research question: Can we enhance monthly hydrous and anhydrous ethanol production prediction for the primary Brazilian-producing states using Artificial Intelligence Models (AIM) How should data be prepared for such an approach This study aims to contribute to logistical planning by employing D-AI2-M - a Data-Centric Artificial Intelligence (DAI) methodology - to aid in selecting AIM for ethanol production time series in the principal Brazilian-producing states. Our quantitative experimental evaluation demonstrates the superior forecasting performance of D-AI2-M in two approaches: i) Local: where different D-AI2-M outperform the benchmark models depending on the specific time series, and ii) Global: where a single D-AI2-M achieves the best mean performance across the complete set of evaluated time series.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"22 11","pages":"899-910"},"PeriodicalIF":1.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10735449","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology is based on the extraction of pectin in an acid medium for 180 minutes at 70, 80, and 90C, evaluating the performance of the product at each temperature. The kinetics of pectin extraction from melon peels and seeds, regardless of the working temperature, presents three stages: rapid release, then a plateau, followed by smooth growth until reaching the maximum amount of the product extracted. This process can be assimilated as a sequence of subprocesses, each with its own delay time and constants time. Based on the experimental results, each stage or period is mathematically modeled as a second-order linear with delay time. This dynamic model takes into account the work matrix, as well as the extraction mechanism used. The deviation of the model concerning to the experimental data is minimal, compared to the empirical and mechanistic models found in the literature for pectin extraction. The latter are based on oversimplified assumptions, leading to significant disparities between experimentally obtained and mathematically simulated results.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"22 10","pages":"829-834"},"PeriodicalIF":1.3,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10706025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces an adaptive data logging algorithm for a cost-effective IoT node, addressing these challenges. This innovation enables real-time data acquisition and remote display via a web interface. Experimental tests demonstrate the prototype's reliability in both controlled indoor and dynamic outdoor environments, particularly in environmental and GPS data collection. Results reveal 5.24% data loss indoors and 23.24% via the web interface. Outdoors, data loss peaks at 55.34%, increasing to 82.76% with the web interface. However, the obtained information is adequate for prototype validation. The algorithm reduces data by 74%, leading to lower data processing and power transmission needs. Moreover, determining the distance from GPS coordinates is essential for predicting travel times and monitoring vehicle velocity to maximize efficiency. The results from this prototype are expected to enhance the development of advanced models, thus enriching future scientific research initiatives that aim to incorporate IoT technology into transportation systems.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"22 10","pages":"842-853"},"PeriodicalIF":1.3,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10705972","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142377148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this work, we executed performance benchmark tests of the YOLOv7-tiny model for real-time object detection using a camera and three embedded hardware platforms: Raspberry Pi 4B, Jetson Nano, and Jetson Xavier NX. We tested and analyzed the NVIDIA platforms and their different power modes. The Raspberry Pi 4B achieved an average of 0.9 FPS. The Jetson Xavier NX achieved 30 FPS, the maximum possible FPS rate, in three power modes. In the tests, it was possible to notice that the maximum CPU clock of the Jetson Xavier NX impacts the FPS rate more than the GPU clock itself.
