This technique allows the identification of hidden data relationships inside a data sequence. The comparison between recurrence plots in order to identify common structures is difficult because the lack of similarity quantification tools in the available software for recurrence plots analysis such as VRA (Visual Recurrence Analysis), RQA (Recurrence Quantification Analysis) and CRP (Cross Recurrence Plots). In this work a software tool for analysis of structural similarity between recurrent plots is proposed, the tool named RecurrenceVs allows the comparison and quantification of similarity between recurrence plots generated from different sequences of data. Also it allows the generation of a classification by their similarity degree between recurrence plots from a set under study. Different datasets from time series to genomic sequences were used to evaluate the performance and usability of this tool.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131509016","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 present research proposes a new semi-active suspension model with a magnetorheological damper, including its dynamics. Three control approaches are applied to this suspension model to improve passenger comfort and vehicle stability. The well known control strategies: skyhook, groundhook and hybrid, are adequated for the model and simulated using Matlab. Exhaustive simulation results compare comfort and stability between an average city car passive suspension and the proposed semi-active suspension. The suspension with hybrid control shows the best performance complying, at the same time, with vehicle stability and passenger comfort.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117098937","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 decoupled controller (one for each image axis) has been developed. Experimental results with the link two(arm) and three(elbow) of the ASEA-IRB6 robot manipulator are presented to illustrate the control system performances.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127292376","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 paper proposes a methodology to analyze the variations in the positions of the 3RRR planar parallel mechanism. This methodology is called point-point and it consists in plotting a straight line inside the workspace as ideal trajectory lines of reference, horizontal as well as vertically, this shifts the mobile platform following the tangents while plotting the points that it obtains. From these points and the reference line the resolution is calculated, and the accuracy and the approximation error to the straight line. It can be concluded that in the 3RRR PPM, the exactitude is different in its horizontal movements then in its vertical movements; and that the resolution does not improve even when the steps (microsteps) are decreased, and the error of approximation increases as it advances in the direction of the tangent no matter if itpsilas a normal step or a microstep.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126565886","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}

Classical techniques for optimizing multi-objective designs are limited when numerous nonlinear behaviors are implied, generating a rise in costs both in computational time and resources. For this reason alternative techniques applying fuzzy logic have been developed for optimizing multi-objective designs of electronic circuits, in particular the Gaussian-like method is an approach widely used for several authors. This paper explains the equivalence of a Mamdani approximation in relation with a Gaussian-like system for performing the control actions of the optimization task, the equivalence is based on a simple functional relation among the parameters of both methods. Two examples in the optimization of active circuits are presented.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120935970","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}

Calcifications are tiny deposits of calcium in breast tissues and they often represent important and common findings in a mammogram. The first step is to apply a segmentation process for eliminating some regions in the image, which are not useful for the mammographic interpretation. Then histogram modification technique is used to improve the contrast of the image and to clarify some details like microcalcifications. Finally DWT (discrete wavelet transform) must be applied for detecting the abnormality. Results were evaluated using the mammographic image analysis society (MIAS) mammographic databases.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121215639","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}
