An Investigation of the Fractal and Multifractal Properties of Biological Time Series Mahsa Hoseini June 2020 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran Degree Master of Science Language Farsi Supervisors Vahid Salari Assist Prof vahidsalari@cc iut ac ir Farhad Shahbazi Assoc Prof shahbazi@cc iut ac ir Abstract Simulation of biological systems is one of the current research topics due to the advancement of science along with the human needs Particularly functioning of the human body is one of the essential issues among them For example our intention here is mainly for diagnosis of epilepsy via correct analysis of the data obtained from brain function Perhaps biological systems are the most complex systems in nature and therefore it is required to simulate them with complex and powerful geometries for investigation In order to analyze such systems Fractional geometry is one of the useful methods i e classified into two general categories Monofractal and Multifractal The aim of this study is to find a better way to analyze biological signals more precisely based on fractional geometry Thus we will first introduce the fractional and multifractional methods and then study each of them in terms of strengths and weaknesses Based on our analyses Higuchi s method and DFA are not suitable methods for monofractal analysis On the other side we consider Chhabra Jensen s and MF DFA methods as potential alternatives for multifractal analysis where we show that the Chhabra Jensen method is more successful than the MF DFA method In fact this method is simpler and unlike the other mentioned methods does not require Legendre transform Consequently we analyze our results based on the Chhabra Jensen method and show its advantages for signal analysis in biological systems Keywords Biological Systems Fractal Multifractal Higuchi Method DFA Method MF DFA Method Chhabra Jensen MethodCopy pdf Copy bb
