The system, besides a manual mode to open and close the windows, incorporates a basic algorithm to read the vehicle's speed thru OBDII protocol (On Board Diagnostics). With the automatic mode engaged, if the vehicle's speed increases, the system opens a little the window, and in a similar way if the vehicle slows down the windows gets lower. For testing it was developed an OBD arduino emulator.","PeriodicalId":137887,"journal":{"name":"2016 IEEE Conference on Mechatronics, Adaptive and Intelligent Systems (MAIS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133075445","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}

Within machine learning domain supervised, unsupervised and reinforcement learning classifications can be found. Among these, the most widely used is supervised learning. This allows two learning tasks: classification and regression. The Gaussian process model is one of the methodologies used for regression. Through regression, a learning process can be performed, allowing to learn by demonstration from a given data set. In this article, the development of a learning method is presented, it is based on Gaussian process regression and intended to be applied in robotic platforms which require to learn quickly and incrementally, since the robots today maintain more contact with the environment and therefore with the human. That is why the Gaussian processes have the characteristics required to develop this type of control for robots. In this paper, a non-parametric regression model such Gaussian process is investigated, as well as how this can be applied to learning from demonstration framework.","PeriodicalId":137887,"journal":{"name":"2016 IEEE Conference on Mechatronics, Adaptive and Intelligent Systems (MAIS)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114505855","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}

A new approach is presented that is different to the state of the art methods for the classification of fingers movements that have traditionally, focused on very well distinguished gestures from each other. Myoelectric signals (MES) reflect the intention of the movement according to the diameter of the sphere sustained is the objective of the present study. Natural motions are collected by placing electrodes on five muscles on the forearm of six healthy subjects, while performing spherical fastenings. A time domain (TD) feature vector is given as inputs to a linear discriminant analysis (LDA) module. LDA is used as statistical pattern classifier. We show that there exist significant relationship between muscle signals and fingers positions. Therefore, it is possible to categorize each class of finger position, that is, TD feature based provide an effective representation for classification. LDA achieve the assignment of the membership of a MES collected to one fingers position class, which is defined by the diameter of sphere. These results will be useful for analysis of movement of the human hand to improve control of robotic prosthetic hand and man-machine interfaces.","PeriodicalId":137887,"journal":{"name":"2016 IEEE Conference on Mechatronics, Adaptive and Intelligent Systems (MAIS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134266380","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 work a SC and a FOC for induction motors are implemented. The goal of this study is to identify the advantages and disadvantages of each controller in conditions such as: load changes, open loop, with or without encoder in a speed profile. Each controller was implemented on the same motor with commercial equipment. Each response is analyzed and explained by graphics considering the performance in different speeds and the response to compensate changes in load.","PeriodicalId":137887,"journal":{"name":"2016 IEEE Conference on Mechatronics, Adaptive and Intelligent Systems (MAIS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123110689","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}
