WEB-tabanlı neurocardiovascular simülasyonu için XML-tabanlı bir çerçeve

ABSTRACTXML-BASED FRAMEWORK FOR WEB-BASEDNEUROCARDIOVASCULAR SIMULATIONİsmail UZUNM.S. in Electrical and Electronics EngineeringSupervisor: Prof. Dr. Yusuf Ziya İDERAugust 2004Mathematical modeling and numerical simulation ofneurocardiovascular control system has played an important role in betterunderstanding of its function and diagnosis of neurological disorders. Currentsimulations of neurocardiovascular models are carried out using desktopapplications, which lack remote access and information sharing facilities.Although, web-technology has penetrated into all areas of research andprofessional life during the past two decades, opportunities provided by theweb technology has not been fully exploited in this area. Moving from desktopto web, utilizing web technology, promises global access, platformindependence, information sharing and easy maintainability features.Considering these features, the demand on a framework that enables web-based simulation of neurocardiovascular system models becomes moreobvious.iiiIn this thesis, we have proposed and implemented an XML-basedframework that enables web-based simulation of neurocardivascular models. Inthis context, we implemented an XML-based description language forstructured description of neurocardiovascular models, a Java-based simulatonpackage and supportive software to form a web-based architecture. XML isbecoming the universal standard for exchange of structured data over the web.Therefore, we make use of XML to propose the generic description languageNeuroCardioVascular Markup Language (NCVML), such that it supportsdescription of a wide range of model set. We expect neurocardiovascularmodel descriptions to be encoded in NCVML form and to be carried over theweb in this format. The java-based simulation package, NCVJSim, contains abuilt-in library with peculiar components and a simulator part. The librarycould be extended in time such that the library evolves in time. Additionally,making use of Java Dynamic Class Loading & Java Reflection Mechanisms,we implemented the feature of incorporating user implemented Java classesduring run-time. Finally, to achieve web-based access and computing, JavaServlet Technology and HTML are utilized.Our proposed framework is developed to serve all types of models,thus, it is not restricted to a particular mathematical neurocardiovascularmodel.Keywords: Web-based simulation, XML, description languageNeurocardiovascular system, Neurocardiovascular models.iv
