As a result, the setup allowed to locate and monitor signals from known satellites using available and inexpensive, \"off the shelve\", commercial components. The encouraging results that were obtained are also described along the paper. The setup design that is presented can be easily replicated as an initial step, and then, scaled into an automated terrestrial station, with a more complex and precise communications system.","PeriodicalId":226698,"journal":{"name":"2015 International Conference on Mechatronics, Electronics and Automotive Engineering (ICMEAE)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126252717","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 simple model is the Randles circuit, which consists of a resistance connected in series with a parallel combination of a capacitance and another resistance. This second resistance is called polarization resistance, and for many practical applications, it is very important to estimate its value. Using a special form of a pulsed excitation, we show that it is possible to estimate a value for the polarization resistance with a very simple calculation. A time-frequency analysis of the proposed pulsed excitation showed not only the zero frequency content of the signal but also the time when this zero frequency occurs. Using Laplace analysis, we show also that the transient current through the capacitance is zero, when the frequency contents of the pulse is zero. In this way it is possible to estimate the value of the resistive component of an electrochemical cell. Experimental results show an approximation error of less than 0.5%. We conclude this is an alternative technique to estimate the polarization resistance.","PeriodicalId":226698,"journal":{"name":"2015 International Conference on Mechatronics, Electronics and Automotive Engineering (ICMEAE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116386865","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 feature extraction method takes advantage of the knowledge related to which parts of the face reflects the highest deformations, so we selected 4 specific facial regions at which the appearance descriptor were applied. The most common approaches used for feature extraction are the holistic and the local strategies. In this work we present the results of using a local appearance approach estimating the correlation coefficient of the 4 corresponding landmark-localized facial templates of the expression face related to the neutral face. The results let us prove how the proposed estimation of non-rigid deformation scheme with the dominant block based on computational correlation can simply and intuitively measure the deformation parameters for some of the most relevant facial regions and how these parameters together can be used to recognize facial expressions automatically.

Five attributes are defined for evaluating: the \"face\" attribute, the \"eyes\" attribute, the \"shoulders\" attribute, the \"mouth\" attribute and finally the attribute \"interested\" in which the others attributes are classified in \"interested\" \"uninterested\" and \"neutral\". 60 instances were stored from five different students and were classified using decision trees found in Weka software, among which were used: ID3, RANDOM TREE, C4.5, BFTREE, REPTree.

Two different situations are considered. In the first situation, the position of the first sample does not have jitter, but it exists in the second sample. In the second condition, the two samples have the presence of jitter. The probability density functions of jitter are represented by the uniform and the Erlang distributions. The results are obtained by applying statistical averaging to the conditional mean rule with respect to the random variable of jitter. This rule defines the conditional variance function as reconstruction error function, which allows us to determine the reconstruction error of the Gaussian Markov process on the whole time domain.","PeriodicalId":226698,"journal":{"name":"2015 International Conference on Mechatronics, Electronics and Automotive Engineering (ICMEAE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132517564","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}
