Although rural areas still have precarious basic services throughout the continent, it is enough with a single non-studying child to conclude that there is no democratization of learning access and technology. The research methodology was a bibliographic review, supported on electronic means to obtain all the relevant and available information about the subject of study. The general conclusion is that regardless of the accessibility to learning that exist in our countries, the important thing is the knowledge that remains, if this is really effective, if the teacher do the class online with the available applications, and also if he has all the technological resources, to teach the class and not only to send the weekly planning of the assignment either by mail, messaging or web platforms, without an evaluation to verify that the student has learned and passed the class or subject","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123127269","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}

Consequently, the integration of the Internet of Things (IoT) has introduced the term Industry 4.0, allowing an ideal connection from the end devices (EDs) to enterprise-level systems. On the other hand, the development of powerful low-cost wireless technologies and long-distance transmission, such as LPWAN (Low Power Wide Area Network), have made it possible to manage the development of Smart Agriculture applications. For instance, a remote monitoring system of physiological parameters in animals, which aims to prevent diseases, and generate sustainable livestock in the environmental and economic aspect. In this work, we propose a web platform prototype for livestock monitoring implemented with LoRa (Long Range) technology and a controller that hosts a server on an inexpensive single board computer such as the Raspberry Pi. This platform allows monitoring of key parameters such as GPS signal and temperature through two EDs. Which use a plate with LoRa/GPS communication and a temperature sensor that allows to visualize the geolocation and health of the cattle.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117230856","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}

One of the best known optimizers is Adam, which main advantage is the invariance of the magnitudes of the parameter updates with respect to the change of scale of the gradient. However, other optimizers are often chosen because they generalize in a better manner. AdamW is a variant of Adam where the weight decay is performed only after controlling the parameter-wise step size. In order to present a comparative scenario for optimizers in the present work, a Temperature Forecast for the Andean city of Quito using a neural network structure with uncertainty reduction was implemented and three optimizers (Adam, AdaMax and AdamW) were analyzed. In order to do the comparison three error metrics were obtained per hour in order to determine the effectiveness of the prediction. From the analysis it can be seen that Adam and AdaMax behave similarly reaching a maximum MSE per hour of 2.5°C nevertheless AdamW allows to reduce this error around 1.3°C.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125363976","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}

Therefore, it is necessary to create spaces for boys and girls to develop skills and competencies required for future employment. The present case study proposes an informal STEM learning program, through the implementation of a camp, in such a way as to provide evidence that exposing children to a video game creation workshop, having as a methodology the engineering design process (EDP) and the Scratch platform as a tool, will positively impact in the children interest's in STEM areas. Four camps were implemented, distributed in five lessons of two hours each, aimed at 60 children from 11 to 13 years of age. The authors present a methodology to measure the effectiveness of the camps through two surveys conducted with the participants before and after the camps, which made it possible to measure learning and interest in STEM areas. Camps increased motivation toward engineering and science careers by 13 % of participants, increased interest in mathematics by 23% of participants, also, increased learning about how to create a video game by 43 % of participants and the number of participants who know about the engineering design process increased by 50%.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703677","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}

Specifically, by considering beamforming at the source (Alice), we study the practical scenario where Alice has Bob's channel state information (CSI); however, she doesn't know Eve's CSI. (i.e., passive eavesdropping case). To this end, we first derive approximate expressions for modeling the RIS cascaded channel applying the Maximum Likelihood (ML) algorithm. This approach allows for incorporating relevant factors into RIS's channel modeling, including phase shift noise, correlation between RIS elements, and coexistence or not of the direct links at both the legitimate and eavesdropper nodes. Based on these findings, we obtain a closed-form solution of the outage secrecy probability for the underlying system. Finally, some valuable insights on how various channel features and the number of RIS elements affect the secrecy behavior are also presented.","PeriodicalId":438567,"journal":{"name":"2021 IEEE Fifth Ecuador Technical Chapters Meeting (ETCM)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114456197","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}
