For instance, the low-cost distance sensor (Lidar Lite v3 Module) is a measuring device that generates different responses depending on the distance between the sensor and the object using laser reflection techniques. Even though this is a useful method, there is not enough information about its performance in different circumstances. Consequently, an evaluation of the sensor has been accomplished in order establish its accuracy in diverse settings such as: material type, temperature and inclination angle. The results are presented in tables, graphs and equations. Moreover, the experiments focus on the percentage error for the measurements. The accuracy of many parameters where confirmed comparing the temperature and distance conditions with the information available from the manufacturer. However, the inclination objects and material type where found different than expected results. The collected information provides a technical perspective for its implementation in prototypes when objects detection and distance is required.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114561145","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 last 15 years, 5 volcanoes in Ecuador have produced moderate to large explosive eruptions. Hence, information about the volcanic ash dispersion in forecasting time is priority in Ecuador. For this purpose we build a system based on the WRF and FALL3D, both Eulerian models, used for forecasting meteorology and volcanic ash dispersion respectively. These models solve numerically the full atmospheric and volcanic ash dispersion governing equations, using finite-difference approximations. Currently this system generates information about the potential path of volcanic ash and the affected areas by ash fallout, owing to eruptions at the Tungurahua and Cotopaxi volcanoes. This paper describes the main components of this system, its advantages, and limitations by analyzing the Ecuadorian case study.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117239046","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 methodology incorporates Static Var Compensators (SVCs) integrated in a power system. The optimization problem is solved using a novel algorithm which consist of two stages. The first stage or the outer layer determines the optimum number, sizing, and placement of the SVCs. The second stage or the inner layer determines the optimum operation of the SVCs. The results reveal that the approach is feasible, and the optimization turns out to be fast and robust in comparison to the classical Particle Swarm Optimization (PSO).","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128372637","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}

There are several methods to extract information from the EEG signal, in this work, we studied three methods to characterize the EEG signals: spectral analysis to measure the power of certain brain regions on alpha band, fractal dimension to measure complexity level of EEG signals and correlation coefficient to measure the level of interhemispheric synchrony. We discuss the advantages of each method and how it could be used in neuroscience. We also present an application example evaluating EEG signal features changes produced as an effect of a meditation program. It was not found a trend effect for all subjects, nevertheless interesting individual behaviors were found, especially in synchrony behavior for corresponding interhemispheric channels.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122472378","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 proposed model incorporates a control system for the injected active power and also to avoid permanent magnet demagnetization. In addition, it considers a high-frequency harmonics filter to mitigate wave distortions at the load side. In order to test the control system stability, the model is subject to abrupt wind speed variations. The results reveal that the proposed modeling can be used in future research for distributed generation applications since it has the capacity to control the power and voltage generated.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126777444","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}

For tuning and getting the best parameters of the controller, the optimization is performed using the evolutionary algorithm PSO (Particles Swarm Optimization), which needs minimize an objective function. In this work, it has been chosen the Integral Square Error (ISE), performance metric that allows knowing how fast the controller takes the system output to the desired reference.

In the case of people with hearing and language impairments, their specific limitations to communicate with other individuals restrict in great amount their development within society. For this reason, the following paper promotes the development of a virtual assistance environment based on electronic gauntlet composed by an artificial voice module, wireless connection and a 2.8-inch screen, which allows the real-time interpretation of sign language. In addition, a human machine interface (HMI) has been implemented through a 3D graphics engine in order to train deaf people and normal hearing society in the use of this system.
