　Anisotropic Fractional Derivative Viscoelastic Models

(Contributed by X.D. Zhang)

So far, almost all researches on the fractional derivative viscoelastic models are focused on isotropic viscoelastic materials, most of these models are even one dimensional constitutive relationship. However, the many natural and engineering materials are anisotropic viscoelastic materials, such as composite materials, biological materials and so on. Although a few literatures proposed the anisotropic fractional derivative viscoelastic models, such as “Anisotropic viscoelastic models with singular memory” by Hanyga, corresponding researches are still under way. How to develop the three dimensional anisotropic fractional derivative viscoelastic models is a key topic in the application of fractional derivative models.

　 The 5th IFAC Symposium on Fractional Differentiation and its Applications - FDA12

（Hohai University, Nanjing, China, May 14-17, 2012）

Co-sponsored by Technical Committee: TC 2.2 Linear Control Systems, International Federation of Automatic Control (IFAC), Chinese Society of Theoretical and Applied Mechanics, Hohai University, Shanghai University

In recent years, fractional differentiation has drawn increasing attention in the study of so-called "anomalous" social and physical behaviors, where scaling power law of fractional order appears universal as an empirical description of such complex phenomena. It is worth noting that the standard mathematical models of integer-order derivatives, including nonlinear models, do not work adequately in many cases where power law is clearly observed. To accurately reflect the non-local, frequency- and history-dependent properties of power law phenomena, some alternative modeling tools have to be introduced such as fractional calculus.
Research in fractional differentiation is inherently multi-disciplinary and its application across diverse disciplines such as physics, chemistry, biology, polymer, medicine, mechanics, finance, social sciences, notably control theory and signal and image processing. This is well reflected by the wide scope of the articles reported in literature. The purpose of this Symposium in series is to provide the participants with a broad overview of the state of the art on fractional systems, leading to the cross-fertilization of new research on theoretical, experimental and computational fronts for potential uses of fractional differentiation in diverse applications.
This series of conferences is the largest of its kind. Following the previous successful conferences, 2004 in France, 2006 in Portugal, 2008 Turkey, and 2010 in Spain, we expect that 200 or so participants from around the world will attend the FDA12.

from Imperial College Press

This monograph provides a comprehensive overview of the author’s work on the fields of fractional calculus and waves in linear viscoelastic media, which includes his pioneering contributions on the applications of special functions of the Mittag-Leffler and Wright types.
It is intended to serve as a general introduction to the above-mentioned areas of mathematical modeling. The explanations in the book are detailed enough to capture the interest of the curious reader, and complete enough to provide the necessary background material needed to delve further into the subject and explore the research literature given in the huge general bibliography.
This book is likely to be of interest to applied scientists and engineers.
Contents:
● Essentials of Fractional Calculus
● Essentials of Linear Viscoelasticity
● Fractional Viscoelastic Models
● Waves in Linear Viscoelastic Media: Dispersion and Dissipation
● Waves in Linear Viscoelastic Media: Asymptotic Representations

Fractional Processes and Fractional-Order Signal Processing: Techniques and Applications

(Hu Sheng, YangQuan Chen and TianShuang Qiu)

In this monograph, we will introduce some complex random signals which are characterized by the presence of heavy-tailed distribution or non-negligible dependence between distant observations, from the ‘fractional’ point of view. Furthermore, the analysis techniques for these fractional processes are investigated using the ‘fractional thinking.’ The term ‘fractional process’ in this monograph refers to some random signals which manifest themselves by heavy-tailed distribution, long range dependence (LRD)/long memory, or local memory. Fractional processes are widely found in science, technology and engineering systems. Typical heavy-tailed distributed signals include underwater acoustic signals, low-frequency atmospheric noises, many types of man-made noises, and so on. Typical LRD/long memory processes and local memory processes can be observed in financial data, communications networks data and biological data. These properties, i.e., heavy-tailed distribution, LRD/long memory, and local memory always lead to certain trouble in correctly obtaining the statistical characteristics and extracting desired information from these fractional processes. These properties cannot be neglected in time series analysis, because the tail thickness of the distribution, LRD, or local memory properties of the time series are critical in characterizing the essence of the resulting natural or man-made phenomena of the signals. Therefore, some valuable fractional-order signal processing (FOSP) techniques were provided to analyze these fractional processes. FOSP techniques, which are based on the fractional calculus, FLOM and FrFT, include simulation of fractional processes, fractional-order system modeling, fractional-order filtering, realization of fractional systems, etc. So, for random signals which exhibit evident ‘fractional’ properties, should be investigated using FOSP techniques to obtain better analysis results.
        This monograph includes four parts. The first part is the overview of fractional processes and FOSP techniques. The second part presents fractional processes, which are studied as the output of the fractional order differential systems, including constant-order fractional processes and variable-order fractional processes. The third part introduces the FOSP techniques from the ‘fractional signals and fractional systems’ point of view. In the last part of the monograph, some application examples of FOSP techniques are presented to help the readers to understand and appreciate the fractional processes and fractional techniques. We sincerely wish this monograph can give our readers a novel insight into the complex random signals characterized by ‘fractional’ properties, and some powerful tools to characterize those signals.

Rudolf Gorenflo is member of several scientific associations. He began working on the research of fractional derivative ordinary fractional differential equations and related special functions in 1992, and later (beginning in 1995) he intensified this work in collaboration with Prof. F. Mainardi and other investigators. Soon these interests were extended to cover partial fractional equations (fractional in time or in space or in both time and space), equations suitable for modelling non-classical diffusion processes. In this collaboration, various types of random walk models were devised and analyzed.
