Methane (CH4) is the second more important greenhouse gas (GHG), respecting its potential global warming. Although cities represent only 2% of the global surface, they are responsible for 70% of the GHGs emissions. Thus, it is necessary to study their atmospheric concentration variations to identify the main sources and mitigate their emissions. The main objective of this study is to estimate the CH4 urban concentration using satellite products. To do this, first the atmospheric CH4 concentration was analyzed in 16 sites in the city of Tandil (Argentina) for one year; thus, the observed data could be registered. It was found that in winter and autumn, the concentrations were higher than in summer and spring. Then, the data from Landsat 8 satellite were used to obtain the Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST). Linear regression was applied, taking into account the seasonal CH4 concentration as the dependent variable, and the NDVI and LST as the independent variables. The adjusted R2 was 0.53, and the principal variable that affected the CH4 concentration was NDVI, which is related to urbanization. Finally, the mathematical expression from the regression was applied to obtain CH4 urban concentration, which allows us to analyze the temporal and spatial variations.

This paper presents the design of a packaging applicable to an experimental optical fiber sensor to measure RH inside concrete structures. RH optical sensor is based on a Long Period Fiber Grating (LPG) functionalized with a suitable humidity sensitive film deposited on it. A functional test was carried out on the final physical sensor configuration to evaluate the impact of using the encapsulation on the sensing performance. Characterization test results are shown taking into account design considerations and assumptions made. Finally, the encapsulation use feasibility is concluded.

En este trabajo, se propone una estrategia de control para un convertidor DC-DC con puentes duales activos que interconecta dos alimentadores de una microrred de DC. La estrategia de control propuesta, permite regular la tensión de salida del convertidor y asegurar que el valor medio de la corriente en el primario y el secundario del transformador de alta frecuencia sea nulo con el fin de evitar su saturación. El convertidor se modela usando la técnica de modelado promediado en espacio de estados generalizado y el controlador es diseñado mediante una estrategia de control no lineal basada en linealización por realimentación entrada-salida. El desempeño de la estrategia de control propuesta es validada mediante resultados de simulación.

This work proposes a MatLab script as a calculation tool to correctly characterize of lightning, modeling and calculation of the performance of power distribution lines against lightning. The electrical system is modeled and simulated to determine the performance of overhead lines considering different combinations of structures and grounding commonly used by electric power concessionaires. For verification and veracity, the results obtained are contrasted with the calculations made in IEEE Std.1410-2010. The results show the correct operation of the algorithm for estimating the performance of the distribution overhead lines.

Social inclusion in energy regulation is a key issue in Honduras, due to the existence of various social, economic, and cultural factors that should be included in any energy project. Honduras is home to several ethnic communities, a young population that is on the rise, an unequal society with a wide gender gap, poor access to opportunities for people with some type of disability, and where both extremes of economic groups converge, those with a high purchasing power as well as those in poverty and extreme poverty. In addition to these, the Honduran population has witnessed many social conflicts such as the coup d'etat in 2009.Honduras is rich in renewable resources for power generation. Thus, the study of the interaction among the supply/demand and social inclusion in energy regulation in Honduras is a very important issue given the growth of energy demand due to the economic development as well as the growth of population.In this work, an overview of the current situation of social inclusion in energy regulation in Honduras is shown. By considering the legislation related to the energy market, the service as a public good of National Security, oil exploration, supply, and demand of electricity as well as the production of biofuels. Finally, some measures to existing legislation and public policies which consider social inclusion in energy regulation in Honduras are proposed.

We propose a receiver circuit for radar systems operating at microwave frequency that consists of a quadrature hybrid coupler connected to two power detectors. The device employs stretch processing to obtain high range resolution with low ADC requirements. We derive and validate a theoretical model of the proposed architecture using a prototype simulation designed for a 5.2 GHz center frequency. The simulation results match the theoretical behaviour and demonstrate that this approach achieves a typical range resolution, up to 37.5 cm, with low cost and low power consumption.

An important issue for agricultural planning is to estimate evapotranspiration accurately due to its fundamental role in sustainable use of water resources. It is essential to have reliable and precise evapotranspiration (ET) measurements to improve models or products. This work aims to evaluate a generalized linear model (GLM) in order to estimate actual evapotranspiration of barley crop with satellite (Landsat, Sentinel, and CERES) and reanalysis (MERRA-2) data. The results obtained were compared with water balance values from an agrometeorological station. The GLM with the combination of MERRA-2/CERES/Sentinel 2 as input was the best performance (R2 = 0.59). The results show the feasibility of applying machine learning algorithms for obtaining actual evapotranspiration values in agricultural plains without ground agro-meteorological data.

Sporobolus spartinus (Trin.) P.M. Peterson & Saarela (=Spartina argentinensis Parodi, common name: espartillo) is a perennial C4 grass that dominates in many communities from a region named "Bajos Submeridionales" in the northern part of Santa Fe province. It produces high quantity of biomass but, due to its low digestibility, cattle risers often burn it in order to stimulate the growth of more tender leaves. This burnt biomass could be used in order to produce bioenergy, thus knowing its availability is mandatory in order to select areas with higher biomass. In this research, S. spartinus biomass reflectance from a farm near the town of Galvez was measured with i: a multispectral camera mounted in a Drone and ii: a hyperspectral camera in a spectrometer in two different dates, one in October of 2019 and the other in March of 2020. S. spartinus biomass presented higher total biomass (average of 7700 kg of dry matter per hectare) in October and most of it (67%) was senescent biomass while in March, total biomass accounted for 5300 kg per hectare and only 38% of it was standing dead biomass. A Normalized index was able to explain 33% of total biomass variability with both instruments. Due to the fact that either green or senescent biomass can be used for bioenergy, our aim was to estimate those using remotely sensed multispectral images.
spartinus(三)下午Peterson & Saarela (=Spartina argentinensis Parodi，通用名称:espartiillo)是一种多年生C4草，在圣达菲省北部名为“Bajos潜水”的地区的许多社区中占主导地位。它产生大量的生物质，但由于其消化率低，养牛者经常燃烧它，以刺激更嫩的叶子的生长。这种燃烧的生物质可以用来生产生物能源，因此了解其可用性是强制性的，以便选择具有较高生物质的地区。在这项研究中，研究人员在2019年10月和2020年3月两个不同的日期，分别用安装在无人机上的多光谱相机和光谱仪上的高光谱相机测量了加尔韦兹镇附近一个农场的S. spartinus生物量反射率。10月米草总生物量较高(平均干物质7700 kg /公顷)，其中大部分(67%)为衰老生物量，3月总生物量为5300 kg /公顷，枯死生物量仅占38%。两种仪器的归一化指数都能解释33%的总生物量变异。由于绿色或衰老的生物质都可以用于生物能源，我们的目的是利用遥感多光谱图像来估计这些生物质。

The Irrigation and Drainage Consortium of Villa Regina, Río Negro is part of a vast, irrigated valley. Its main production is pears and apple crops. Throughout the years, water and drainage problems have been detected due to a water table raise. Studying the zone extensively becomes crucial in order to understand the groundwater and surface water sources interaction and remote sensing information may enable the analysis and understanding of the hydrological behavior of the basin. The aim of this study is to detect variations in the surface water area in the Río Negro in years with contrasting hydrological conditions by using spectral indexes and relate them to water table levels. Sentinel 2 images were used in order to analyze the surface water area. Spectral indexes NDWI and MNDWI were calculated for periods of different flows: 318.66 m3/s (August 2017) y 1157.18 m3/s (August 2018). Unconfined aquifer piezometers near to the river were selected to elaborate piezometric graphs and calculate water table average elevation. The NDWI and the MNDWI indexes were consistent with the river flood in 2018, showing an increase of the water covered area of 420,000 m2 with regard to 2017. The analysis of piezometric graphs during the specific period showed an average elevation of the water table level of 0.7 m. These results suggest the interaction between the river flood and the water table in the studied area. It is possible to conclude that the use of geographical information can contribute to analyze and understand this interaction and can be used as a complement to design proper integrated water management programs for the Alto Valle of Rio Negro and Neuquén.

En el presente trabajo se implementó un módulo para la detección de fallas en sensores de registro de variables en procesos continuos, el cual se desarrolló sobre la base de una máquina de soporte vectorial. Con el fin de obtener una arquitectura adecuada de la máquina, se estudió el desempeño del módulo para diversas implementaciones obtenidas a partir de diferentes técnicas de codificación múltiple y maquinas Kernel. En particular, se analizó el desempeño de las máquinas de soporte implementadas en términos de su capacidad para detectar y clasificar fallas típicas en sensores de procesos continuos. Para cada máquina implementada, se escogió el tamaño del conjunto de entrenamiento y los valores de los hiperparámetros correspondientes a cada una a partir de una búsqueda de tipo rejilla. Los resultados mostraron que el mejor desempeño en términos de exactitud en el testeo se obtuvo para una codificación de tipo One Vs Rest, utilizando un Kernel de tipo función de base radial, para la cual se alcanzó una exactitud superior al 98%.

Con el fin de obtener una arquitectura adecuada de la máquina, se estudió el desempeño del módulo para diversas implementaciones obtenidas a partir de diferentes técnicas de codificación múltiple y maquinas Kernel. En particular, se analizó el desempeño de las máquinas de soporte implementadas en términos de su capacidad para detectar y clasificar fallas típicas en sensores de procesos continuos. Para cada máquina implementada, se escogió el tamaño del conjunto de entrenamiento y los valores de los hiperparámetros correspondientes a cada una a partir de una búsqueda de tipo rejilla. Los resultados mostraron que el mejor desempeño en términos de exactitud en el testeo se obtuvo para una codificación de tipo One Vs Rest, utilizando un Kernel de tipo función de base radial, para la cual se alcanzó una exactitud superior al 98%.","PeriodicalId":318846,"journal":{"name":"2022 IEEE Biennial Congress of Argentina (ARGENCON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127751127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
