This document presents the design and implementation of an electro-mechanical system for the simulation of medical scenarios of the respiratory system of neonatal patients. The system implements three possible scenarios, including the application of a chest massage technique developed at the School of Medicine at Universidad Nacional. The system uses two graphical user interfaces (GUI). In the first GUI, a medical situation is created by a doctor using a series of parameters representing important clinical data. The second GUI presents the scenario to the student about to carry on his/her practice. After being presented the scenario, the student must evaluate the symptoms shown in the emulator, as well as the vital signs graphs or values shown in the interface and respond by applying a treatment to the emulator whose response indicates if the procedure was appropriate.","PeriodicalId":274362,"journal":{"name":"2012 VI Andean Region International Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125853509","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}

Previous work has suggested that using automated techniques to recover decisions and structures from whichever project artifacts are actually kept may be a reasonable solution, but empirical evaluations of this claim are scarce. This article describes: (1) the TREx design decision and architecture structure recovery technique and tool, (2) precision and recall measures of recovery effectiveness for system structure, and (3) an experimental design to evaluate design decision and structure recovery approaches. An initial experimental evaluation of manual versus tool-supported TREx shows that using the tool increases recall, but yield mixed results on precision: decrease structure recovery precision, but increase decision recovery. Also anecdotic evidence suggest that only Experts were systematically better in recovering decisions without tool-support. A replicable experimental package has been published.","PeriodicalId":274362,"journal":{"name":"2012 VI Andean Region International Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121632098","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 information is processed in three stages: feature extraction using cepstral coefficients and the myoelectric signal entropy, pattern classification using a perceptron neural network and data fusion from a Kalman filter. A compatibility test is introduced based on Mahalanobis distance with the aim to detect possible artifacts to come from the estimated angle at the neural network output. The method was tested in healthy subjects, and the results were compared with another work that was based solely on myoelectric signals. The results showed that the use of additional information related to proprioception improves the precision of the knee joint angle estimation, and reduces artifacts.","PeriodicalId":274362,"journal":{"name":"2012 VI Andean Region International Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128648549","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 approach is based in the use of first order Model of Volterra-Laguerre (VLM) and based in this criterion the laminator system is then identified by using input-output data obtained from the system. For this purpose a set of Orthogonal Functions contained in a finite Basis (OBF), were used to represent the Volterra kernels, such that the nonlinearities and changes in the \"time varying system\" were tracked faithfully. Finally, the number of Volterra kernels is strongly reduced, thereby yielding a model much more tractable.","PeriodicalId":274362,"journal":{"name":"2012 VI Andean Region International Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122209136","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 changes in diameter of retinal vessels are an important sign of diseases such as hypertension, arteriosclerosis and diabetes, and may be used for the prevention of further consequences caused by the hypertension such as heart attack, brain stroke and renal failure. Those changes are reflected as arteriolar narrowing which changes the vessel caliber, and modify the arterious venous rate (AVR). Obtaining precise measurements of vascular widths is a critical and demanding process in automated retinal image analysis. A prototype system is developed for measuring the vessels caliber, calculates the AVR and determines the presence of Hypertensive Retinopathy. The process is implemented using different techniques of image and signal analysis including Gabor wavelet, gradients, morphological operations and Niblack. A classification algorithm is also implemented to separate veins from arteries. The diameter measurement is based on the image skeleton and the perpendicular segment of the vessel. The results obtained are presented.","PeriodicalId":274362,"journal":{"name":"2012 VI Andean Region International Conference","volume":"Spec no 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114480817","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}
