Thus, several techniques have been proposed to mitigate its effects. These techniques include the so-called opportunistic transmissions, which are characterized because the transmission of the information is made only when the instantaneous fading amplitude is above a threshold value. The performance of this kind of technique has been evaluated in different works employing square quadrature amplitude modulations (S-QAM). Unlike those works, the opportunistic transmission performance is evaluated considering non-square quadrature amplitude modulations (NS-QAM). In particular, 8-QAM and 32-QAM constellations are considered. The system model considers the presence of additive white Gaussian noise and flat and slow Rayleigh fading. The performance analysis is based on the mean bit error rate as a function of the signal-to-noise ratio. For this, Monte-Carlo simulations are carried out in some relevant scenarios. Additionally, comparisons between the performance of S-QAM and NS-QAM are also made.","PeriodicalId":217788,"journal":{"name":"2019 IEEE Fourth Ecuador Technical Chapters Meeting (ETCM)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126091806","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}

Each unit is integrated with an XBee S2B antenna to enable cost-effective and energy-efficient mesh capabilities for inter-unit communication when two or more units conform the system. Moreover, each unit is also an Internet-of-Things (IoT) device that transmits water-tank levels and sensor-data to a local supervising microcontroller (MCU) via Open Sound Control (OSC). This MCU is, in turn, capable of communication with a cloud-based data plotting / storing and remote-control platform—viz., Adafruit IO—via Message Queueing Telemetry Transport (MQTT). The interface with Adafruit IO enables a remote administrator (a) to monitor water-tank levels and sensor readings, and (b) to execute manual overrides in the system—for example, any or all of the units may be shut-down remotely. When only one unit conforms the system, its water-tank services the toilet-tanks and/or irrigation points connected to the unit. When two or more units conform the system, their water-tank outputs are physically linked, enabling any unit to contribute to the servicing of a variety of connected toilet-tanks and/or irrigation points. In both single or multi-unit configurations, water redistribution is impartial to any end-point at initialization, yet over time the system identifies which end-point(s) require(s) water with a higher frequency and selectively prioritizes servicing to it/them to guarantee prompt refill / supply. The present work is part of ongoing developments of features and services that attempt to imbue the builtenvironment with intelligence via Information and Communication Technologies (ICTs).","PeriodicalId":217788,"journal":{"name":"2019 IEEE Fourth Ecuador Technical Chapters Meeting (ETCM)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132718543","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 defiance emerged with the creation of the Presidential Commitment No. 21898 of April 11th, 2014, which declared the support to the production of electric vehicles as a preventive measure to reduce the polluting emissions produced by the consumption of fossil fuels that affect the health and increase the greenhouse effect in the planet. For this reason, the Universidad Politécnica Salesiana developed an engagement Project with society that consisted in the diffusion at a national level, of this new technology in High Schools of the city of Guayaquil. This article presents the biannual planning of a series of talks in high schools during the academic period No. 53 and the problems that arise while making students aware about the use of electric and hybrid vehicles technology which favor the United Nations′ goal No. 7 about Affordable and Clean Energy. Finally, through a survey conducted in the Javier High School of Guayaquil, the assessment of the Project is shown which responds to the new technological environment of the XXI century.","PeriodicalId":217788,"journal":{"name":"2019 IEEE Fourth Ecuador Technical Chapters Meeting (ETCM)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132733700","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}

In the OGTT, insulin and glucose levels are measured in five different blood samples: a sample in fasting (minute 0) and four others after oral intake of 75 gr. of glucose, at intervals of 30 minutes (minute 30, 60, 90 and 120). The values of glucose at 0 and 120 minutes from OGTT are used for the diagnosis of IFG and IGT, respectively. Several parameters had been used to diagnose the IGT and IFG, such as abdominal circumference, HOMA-IR, area under the curve of glucose during OGTT, among others. However, none of these studies have explored obtaining cut-off points from the area under the curve of insulin (AUCI) during OGTT for IGT and IFG diagnosis. For this propose a database of 172 subjects with values of glucose and insulin during OGTT was used. To assess the predictive capacity of AUCI the receiver operating characteristic (ROC) curves were performed and it was calculated the area under the ROC curve (AUCROC), negative predictive value (NPV) and positive predictive value (PPV). The results show that AUCI can predict the IFG (AUCROC=0.71) and IGT (AUCROC=0.65). The AUCI can discriminate between the subjects that undergo IFG and IGT in concomitance from the subjects that only undergo one of the pathologies. All these findings suggested that AUCI could be used as a diagnostic method for IFG and IGT.","PeriodicalId":217788,"journal":{"name":"2019 IEEE Fourth Ecuador Technical Chapters Meeting (ETCM)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116622884","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}
