García, Eduardo Zamudio-Huertas","doi":"10.14483/23448393.19667","DOIUrl":"https://doi.org/10.14483/23448393.19667","url":null,"abstract":"Context: This article presents the real-time estimation of temperature (°C) and relative humidity ( %) (interval of 16 seconds) for the city of Bogota DC via the Internet of Things (IoT).\u0000Method: This prototype is based on the Arduino ESP8266 NodeMCU module and the DHT11 sensor, as well as on a server-client HTPP communication protocol viaWi-Fi, with remote access to information. 16 sensors were installed in Bogota DC. These sensors send the observed data to the MATLAB storage cloud (ThingSpeak) via theWi-Fi module and can be downloaded in real-time. The temperature (°C) and relative humidity ( %) values were calibrated based on measurements made by the TTH002-certified digital thermo-hygrometer.\u0000Results: Based on the average temperature and relative humidity obtained, two maps were elaborated by implementing QGis: one with the isotherms and another one with isohumes. The inverse distance weighting (IDW) interpolation algorithm was used.\u0000Conclusions: The use of monitoring devices based on the IoT significantly contributes to automating meteorological data and structuring and utilizing robust databases in the field of Civil Engineering. Thus, the real-time transmission of temperature and relative humidity data allows for the online analysis of variables. Finally, the term adaptive dynamic cartography is proposed, which is associated with the generation of maps via the IoT, through which changes in the observed variables are displayed in real time, which allows monitoring the variables making adjustments based on an interpolation algorithm, as well as automatically and instantaneously generating isolines, which significantly reduces the uncertainty implied by the spatial-temporal resolution of current cartography.","PeriodicalId":41509,"journal":{"name":"Ingenieria","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66703901","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}

Como base de comparación se emplea la metodología propuesta por el grupo ARCOSES de la Universidad Distrital, y se realiza una búsqueda de literatura relacionada principalmente en el ámbito latinoamericano.\u0000Método: Esta revisión de la literatura se realizó con base en las siguientes palabras clave: diagnóstico sectorial, análisis sectorial, caracterización sectorial y análisis de sector. Las bases de datos consultadas fueron Dialnet, Iseek, ScienceReseach, Lareferencia, Scielo, Redib, BASE, Springer Link, Scopus y Science Direct. Se seleccionaron los documentos que aplicaron un diagnóstico sectorial o indagaron sobre aspectos metodológicos. Posteriormente, se realizó un análisis de cada trabajo, comparándolo con las variables propuestas por el grupo ARCOSES.\u0000Resultados: No se encontraron diferencias significativas entre las metodologías; muchos trabajos partían de la recolección de datos e información para después realizar estadística descriptiva. En otros, se aplicaban métodos y herramientas más específicos, dependiendo de lo que se quisiera evaluar en el sector. Algunos de los diagnósticos sectoriales contaban con marcos teóricos y conceptuales, además de planteamientos de hipótesis, que se aceptarían con base en la estadística inferencial. Se destaca la importancia de esta temática en el futuro, debido a las distintas problemáticas asociadas a varios sectores económicos con respecto a factores ambientales, sociales y políticos.\u0000Conclusiones: Hay gran dificultad en el diseño de una metodología de uso general. Por lo tanto, es recomendable partir de metodologías previas y realizar modificaciones pertinentes dependiendo del sector de estudio. Se resalta la importancia de la fase de recolección de datos e información sobre un sector, ya que puede involucrar una gran cantidad de retos, incrementando los tiempos de elaboración de los diagnósticos sectoriales. Desde la academia, la investigación futura puede estar orientada al diseño de metodologías particulares que permitan encontrar, de manera eficiente, datos e información que sean de utilidad para el crecimiento económico de un sector.","PeriodicalId":41509,"journal":{"name":"Ingenieria","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49472562","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}

The aim of this paper is to carry out a bibliometric analysis of the scientific production on SSI during the period 2017-2022.Method: A complete bibliometric analysis of all publications on SSI indexed in Scopus and Web of Science was carried out. A corpus of 143 articles was examined by processing their bibliographic metadata on a bibliometric tool. In order to do this, the Bibliometrix packageand the R programming language were used.Results: A bibliometric characterization of the publications on SSI was obtained for the 2017 − 2022 period. The most important keywords used in these publications were identified, as well as their use tendencies throughout this period. Moreover, the most influential authors in the area and the most relevant publication sources were also identified.Conclusions: The results of the bibliometric analysis show that Lotka’s and Bradford’s laws apply for academic publications on SSI, which means that the most relevant publications in this area are concentrated in a relatively small group of authors and journals. Paul Jenkins, Nitin Naik, Yang Liu and Aijun An were the most impactful authors, and Lecture notes in computer science, Frontiers in blockchain and IEEE were the most influential journals. Finally, the keyword analysis showed that Blockchain, Authentication, Identity management, Electronic document identification systems, and Digital identity are currently the most relevant concepts for SSI.","PeriodicalId":41509,"journal":{"name":"Ingenieria","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49594142","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}

Hence, the concept of Logistics 4.0 was born. Although many developed countries have implemented the principles of Logistics 4.0, there is still a breach in its study and application worldwide. This article explores the challenges and tendencies in the implementation of Logistics 4.0. Method: Articles published from 2015 to 2021 in the databases of Scopus, Science Direct, Taylor and Francis and Google Scholar, were analyzed by a systematic literature review. The explored publications were found using the search terms: ((\"logistics 4.0\") OR (\"supply chain 4.0\") OR (\"industry 4.0\" AND (\"logistics\" OR \"supply chain\"))) and ((“blockchain” OR “IoT” OR “Cyber Physical Systems” OR “Big Data”) AND “logistics”) in title, abstract and keywords. Results: It was proposed a conceptualization of Logistics 4.0 including definition, objectives, characteristics, and most representative technologies in its implementation. Likewise, the main challenges and trends that industries could face in the implementation of Logistics 4.0 within logistics systems, and supply chains were identified. Conclusions: Logistics 4.0 is a novelty term that has aroused the interest of researchers, governments, and companies worldwide, due to its promising benefits in reducing response times and increasing flexibility and collaboration in supply chains. However, the lack of a common framework for its study and adoption has hindered its integration in companies and supply chains, specially in those located in developing countries, which must face technical, social, economic, and legal barriers for the implementation of logistics 4.0.","PeriodicalId":41509,"journal":{"name":"Ingenieria","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135582718","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}
