For the frequency control, the speed regulation by ballast load method has been used. To this approach, a combined binary-continuous load regulation was employed. The implemented AVR is totally self-excited by means of an energy transfer system which allows an isolated operation of the MHP. The entire system has been designed considering the current standard regulations of the Ecuadorian Agency of Electricity Control and Regulation (ARCONEL). The frequency and the voltage regulation were properly achieved through the implementation of digital PI controllers tuned based on mathematic models obtained from experimental data of frequency and voltage. The control of the system was validated by both, software simulations and field tests performed.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"87 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83930279","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 GSR phenomenon allows to supervise the variation of the human skin resistance, because it changes in function of the sweat amount production, which in turn varies according to the emotion or feelings of a person at any moment, in order to evaluate his/her emotional conditions in a determined moment, measuring both its resistance and correlating. Among GSR monitor applications are devices to aid psychological treatments, or components of polygraph or lie detector. This paper includes the design and construction of a data acquisition system, and the digital processing of the acquired data is through an embedded reconfigurable system based on NIOS II microprocessor of Altera Corporation. This paper also provides results of the skin resistance variation in a sample of persons under several test cases, plus the results correlated with the intensity of their emotions.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"5 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90868748","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}

This article presents a system which uses the accelerometer and gyroscope sensors in smartwatches to quantify the tremors in patients with Parkinson's disease. The system is based on a Wireless Body Area Network composed by multiple sensor nodes (Android Wears) and one sink node (Android Smartphone). The system integrates four processes: user authentication, placement of sensors on the body, movement sensing and data uploading. The system was evaluated in 12 patients with PD (five males and seven females) while they were doing several activities, but in this article we only analyses when the patients were seated at rest. The patients had an average disease duration of 6.25 years, an average age of 66.33 years and a range of 5186 years. The tremor magnitudes were presented in the form of linear acceleration and angular velocity in the time domain. The results indicate that these variables can determine Parkinson's disease evolution in a patient diagnosed with stage 3 and 4.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"73 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80922535","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}

This task is performed at each power station with the load frequency controller. On wider areas, the energy management systems supervise generation control automatically to preserve stability and reliability. Due to the unpredictability of the demand, the control response must be as fast as possible to prevent larger deviations that could lead to cascading failures and outages. In order to understand the dynamic behavior and capabilities of the controllers, real time simulation offers a great advantage over its offline predecessors, not only for operational training but also for prototyping. This paper studies the effectiveness of the real time simulator in the analysis of a power system load frequency control.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"33 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78584541","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 this study, a comprehensive connectivity analysis of the published genome-scale metabolic model of Synechococcus elongatus PCC7942 (iSyf715) is presented, highlighting the most connected metabolites of this biological system. To get a suitable fit, the connectivity distribution of the metabolic model is evaluated using the cumulative distribution function (Pareto's law), verifying a power-law distribution in iSyf715 metabolic network (3=2.203). Additionally, through the comparison of the connectivity distributions in different microbial metabolic network models, the scale-free behavior of these metabolic networks is verified. The prediction of the metabolic network connectivity could supports the determination of the underlying functioning principles of certain cellular processes.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"42 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83659399","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}

We hypothesized that an electronic, portable, and low cost device that can provide objective, quantitative measurements of serum turbidity might have the potential to improve the early detection of neonatal sepsis. The design features, testing methodologies, and the obtained results are described. The final electronic device was evaluated in two experiments. The first one consisted in recording the turbidity value measured by the device for different solutions with known concentrations and different degrees of turbidity. The second analysis demonstrates a positive correlation between visual turbidity estimation and electronic turbidity measurement. Furthermore, our device demonstrated high turbidity in serum from two neonates with sepsis (one with a confirmed positive blood culture; the other one with a clinical diagnosis). We conclude that our electronic device may effectively measure serum turbidity at the bedside. Future studies will widen the possibility of additional clinical implications.","PeriodicalId":6480,"journal":{"name":"2016 IEEE Ecuador Technical Chapters Meeting (ETCM)","volume":"23 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78180022","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 results would indicate that under certain circumstances the formulation I/O is valid by a 10% of error respect to the Meo-Ajmone model.
