Water Level Monitoring System Based on LoPy4 Microcontroller with LoRa technology 基于LoRa技术的LoPy4单片机水位监测系统
Jhonny Guaman, Fabian Astudillo-Salinas, Andrés Vázquez-Rodas, L. I. Minchala, Sebastian Placencia
Modern weather stations allow real-time monitoring of several atmospheric variables. Wireless Sensor Networks (WSN) provide communication between nodes and the Network Coordinator (Gateway). This network uses transceivers to send the data generated by the stations. The use of WSN in remote locations involves the construction of repeaters because there is no cellular signal or an access network. This article presents the development of a datalogger for stations that measure river water levels of the andean region. The LoPy4 microcontroller is used. This solution combines easy sensor configuration via WiFi and long-range transceiver with LoRa (Long Range) technology. The proposed datalogger has a solar power supply and allows real-time data transmission using the SX1272 transceivers, while a GPRS module is integrated in the coordinator for transmission to the monitoring station server. A GPRS module is integrated into the gateway to forward the data from the stations to the data center.

Erick Candela-Mendoza, Lilian Cruz-Ipanaque, Jimmy Armas-Aguirre
In this paper, we proposed a mobile technology model to ambulatory healthcare information online using cloud platform. This proposal has health indicators and geolocation services that could reduce the time of ambulatory healthcare. Our proposed model also emphasizes the application of real-time data analysis for the healthcare organization. In this process, we also assessed the current technologies and information systems that are used for the healthcare of a patient before a medical consulting. The model consists of four phases: 1. The selection of structured data; 2. The integration and storage of data in a cloud database; 3. Real-time data test using a data analysis service; 4. The results of the pharmacological consulting are shown through a mobile application and the geolocation service can determine the nearest drugstores close to the current patient location. The mobile technology model was validated and tested in a health center in Lima, Peru, to reduce the healthcare timing by benefiting with so that patients can use it, benefiting from the immediate online response to a medical consulting.

Economic analysis of incentives in the electric cars deployment in Latin American 拉丁美洲电动汽车发展激励机制的经济分析
E. Ramirez, J. Torres
World countries societies are concerned with environment protection, seeking the best alternatives to mitigate externalities that affect it, such as fossil fuels use. The second sector after of the industry responsible for emitting greenhouse gases is transport. The United States, Norway, Sweden, China, and other countries are in a process of Electric Vehicles migration although still very slow but in the future will be massive. One of the barriers that does not allow to accelerate its deployment is its high initial cost and the lack of load infrastructure. Considering Electric Vehicle deployment in Latin American is still incipient, there is a need to look for alternatives to boost its deployment.The present study simulates strategies based on assumptions in the application of incentives and taxes that allows to evaluate price of an Electric Vehicle. The results indicate that the best conditions are given to the extent that governments make effort to incentivize through of tax reductions according to the tax structure in each country, such as importation, equity, sales and those that are selective. It is important to have a contribution through subsidies or other benefits that come from the possession the vehicle to replace. Finally, this study considers also those benefit originated by its use during a period of 8 years.
世界各国社会关注环境保护,寻求最佳替代办法,以减轻影响环境的外部因素,例如化石燃料的使用。排在温室气体排放行业之后的第二个部门是交通运输业。美国、挪威、瑞典、中国等国家正处于电动汽车迁移的过程中,虽然现在还很缓慢,但未来将是大规模的。阻碍其加速部署的障碍之一是其高昂的初始成本和缺乏负载基础设施。考虑到电动汽车在拉丁美洲的部署仍处于起步阶段,有必要寻找替代方案来促进其部署。本研究模拟了基于激励和税收的应用假设的策略,以评估电动汽车的价格。结果表明,政府根据每个国家的税收结构,如进口、股权、销售和选择性的税收结构,努力通过减税来激励,从而达到最佳条件。重要的是,通过补贴或其他来自拥有车辆更换的好处来做出贡献。最后,本研究还考虑了在8年期间使用它所产生的益处。

Applying the Grey Systems Theory to Assess Social Impact from an Energy Project 应用灰色系统理论评价某能源项目的社会影响
Alexi Delgado, I. Romero
Energy projects, in some cases, became in causes of social conflicts, in this way and in order to prevent social conflict is it necessary to make a social impact assessment (SIA) before the implementation of an energy project. In this work, a method based on grey systems theory to assess social impact from a hydrocarbon exploration project in Valencia, Spain, was applied. In this case study, three stakeholder groups (G1-G3) and four criteria of evaluation (C1-C4) were determined. The results of this study showed the energy project would have a negative total social impact. These results could help to local and central authorities to make the best decision about the energy project. The quantitative method applied in this study showed interesting results and it could be applied to assess social impact from other types of energy projects.

Alexander Hilario-Tacuri, Alberth Tamo
This paper presents the development of analytical expressions that can be used in the evaluation of the rainy channels effects on the bit error rate (BER) performance of millimeter-Wave (mm-Wave) based systems. In order to obtain these expressions is used a rainy channel model that no only consider the path-loss attenuation but also the absorption and scattering losses caused by the rain. The resulting mathematical expressions are applied to specific situations, allowing a quantitative evaluation of the BER degradation.

Linear Quadratic Regulator Applied to the Load-Frequency Control Problem Considering Reheat Steam Turbine Generators 线性二次型调节器在再热汽轮发电机负荷-频率控制中的应用
R. F. Souto, Raphael Augusto de Souza Benedito
Frequency stability plays an important role in the electric power systems researches, and it is associated with the ability of the system to regulate and maintain constant the electric frequency of the network. Traditionally, classical control techniques are applied to perform frequency regulation, but although they present good results, it is probable that modern control techniques achieve better ones. In this sense, the aim of this paper is to design a modern controller to the frequency regulation problem, based on the the concepts of optimal control theory. It is considered that the generating units of the system are mainly constituted of reheat steam turbines, and some assumptions are made in their dynamics to simplify the system modeling. The proposed controller is tested via computational experiments in scenarios in which the turbine model adopted for the control design is mismatched with the turbine model used in the actual system.

频率稳定性在电力系统研究中占有重要地位,它关系到系统调节和保持电网电频率恒定的能力。传统上,采用经典控制技术进行频率调节,但尽管它们表现出良好的效果,但现代控制技术很可能达到更好的效果。从这个意义上说,本文的目的是基于最优控制理论的概念,设计一个现代的频率调节问题控制器。考虑系统的发电机组主要由再热汽轮机组成,并对其动力学进行了一些假设,以简化系统建模。在控制设计中采用的水轮机模型与实际系统中使用的水轮机模型不匹配的情况下,通过计算实验对所提出的控制器进行了测试。并与经典控制器得到的结果进行了比较。

Traditionally, classical control techniques are applied to perform frequency regulation, but although they present good results, it is probable that modern control techniques achieve better ones. In this sense, the aim of this paper is to design a modern controller to the frequency regulation problem, based on the the concepts of optimal control theory. It is considered that the generating units of the system are mainly constituted of reheat steam turbines, and some assumptions are made in their dynamics to simplify the system modeling. The proposed controller is tested via computational experiments in scenarios in which the turbine model adopted for the control design is mismatched with the turbine model used in the actual system. The results are compared to that obtained by the classical controller.","PeriodicalId":305576,"journal":{"name":"2018 IEEE XXV International Conference on Electronics, Electrical Engineering and Computing (INTERCON)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131990834","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}
