The longest common subsequence (LCS) is a measure of similarity between two sequences. An extension of LCS measure is the constrained longest common subsequence (CLCS). The CLCS consists of calculating the LCS of two sequences, and it is a supersequence of a constrained sequence. This paper is an experimental evaluation of the most important CLCS algorithms. The implemented algorithms have a similar performance and were tested with different kinds of random strings belonging to the alphabets: generated uniformly at random (4, 10, 20, 32, 48 and 64 characters) and English text (239 characters). This study could help in selecting optimal algorithms for a given problem.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"7 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":"115719197","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 general, haptic devices can be classified as active and passive. In this paper, we present a performance evaluation of a group of 10 voluntary subjects in a task of shape perception when both active and passive kinesthetic haptic feedback are provided. The results of a series of psychophysical experiments show that active haptics is superior for shape recognition: active haptics enhances the perception of surfaces while passive haptics conveys the sensation of being guided along pathways. In addition, the guidance nature of passive haptics makes the pathway direction easy to recognize. This last observation can be effectively exploited in more challenging tasks such as navigation/mobility assistance.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","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":"114425744","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 usual master-slave network architectures were replaced by a point-to-point architecture in industrial protocols such as ModBus TCP / IP, thus reducing the number of packets, to send only information on status changes or control. User - Machine Interface (UMI) is coined to show the changes in the state of the industrial process. Since the control and monitoring of industrial processes (locally) uses a human-machine interface (HMI), the need to use a new interface is detected to perform efficient communication, this could allows remote monitoring and control.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"86 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":"130578546","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}

Therefore, the main objective of this research was to obtain a biopolymer developed through the conversion of orange peels. The use of tree structures allowed relating different variables that could have influence in the formulation of bioplastics. The variables that had more weight are the ratios of starch used in the formulation, the method to cool down the mix, and the drying method. In order to achieve the best biopolymer, the best variables were the use starch 100%, cooling at room temperature and dehydration for drying.

In an induction motor, is possible to develop a series of testing to evaluate the condition of its insulation system. The insulation system of an induction motor is subjected to various stresses, which degrades their characteristics day. Therefore, monitoring their condition is key to guide decision making by those in charge of their operation. In this work, a new methodology for evaluate the condition of the insulation system of induction motors based in a health index is proposed. This proposal uses a health index based on a classic method of construction, combining expert criteria with a validation using real data of motors repaired. Several study cases are required to adjust the parameters used to calculate the health index. Once the parameters of the health index are adjusted, the operating condition of several induction motors are established to test the effectiveness of the proposed tool. The results show a good performance evaluating induction motors repaired in an electric motor workshop that participated in this work. This also indicates that moving towards the use of a health index for evaluate induction motors might enhance the behavior (reliability) of an industrial plant (as a whole).","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"1 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":"129303783","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 show the importance of developing an accurate noise generator in terms of its statistics. In this regard, there is a trade-off between the accuracy of the noise samples and the complexity of the generator.

The last week winter period demand profile compared to the first week summer period demand profile are shown and analyzed. Results have shown DST effects on energy consumption in university facilities. With these results, it is also possible to develop decision-making programs to drive energy efficient plans in university campus.
