New Challenges in Fractional Systems

 

The Special Issue “New Challenges in Fractional Systems” is posted on the journal Mathematical Problems in Engineering, Hindawi; at website: http://www.hindawi.com/journals/mpe/osi/

 

Fractional order differentiation consists in the generalization of classical integer differentiation to real or complex orders. From a mathematical point of view, several interpretations of fractional differentiation were proposed, but there is still a deep debate about it. The fractional differentiation and fractional integration are non-local operations based on an integral with a singular kernel. This explains why these operators are still not well defined and that several definitions still coexist. Since the first recorded reference work in 1695 up to the present day, many articles have been published on this subject, but much progress still to be done particularly on the relationship of these different definitions with the physical reality of a system. A fractional order system is a system described by an integro-differential equation involving fractional order derivatives of its input(s) and/or output(s). From a physical point of view, linear fractional derivatives and integrals order systems are not classical linear systems, and not quite conventional distributed parameter systems. They are in fact halfway between these two classes of systems, and are a modelling tool well suited to a wide class of phenomena with non-standard dynamic behaviour, and the applications of fractional order systems are now well accepted in the following disciplines:

 

– Signal processing (filtering, restoration, reconstruction, analysis of fractal noises, ...);
– Image processing (fractal environment modelling, pattern recognition, edge detection, ...);
– Economy (analysis of stock exchange signals, ...);
– Electrical engineering (modelling of motors, transformers, skin effect, ...);
– Electronics, telecommunications (phase locking loops, ...);
– Electromagnetism (modelling of complex dielectric materials, ...);
– Electrochemistry (modelling of batteries and ultracapacitors ...);
– Thermal engineering (modelling and identification of thermal systems, ...);
– Mechanics, mechatronics (viscoelasticity, vibration insulation, ...);
– Automatic control (system identification, observation and control of fractional systems, ...);
– Biology, biophysics (signal and models of biological systems, viscoelasticity in biology, ...);
– Physics (analysis and modelling of diffusion phenomenon, ...).

 

The goal of the present special issue is to address the latest developments in the area of fractional calculus application in signals and systems. Papers describing original research work that reflects the recent theoretical advances and experimental results as well as open new avenues for research are invited on all aspects of object tracking.

Topics in Fractional Differential Equations

Saїd Abbas, Mouffak Benchohra, Gaston M. N’Guérékata

(From: FCAA, Vol. 15, No. 4)

http://www.springer.com/mathematics/dynamical+systems/book/978-1-4614-4035-2.

Ser.: Developments in Mathematics, Vol. 27; ISBN: 978-1-4614-4035-2.

During the last decade, there has been an explosion of interest in fractional dynamics as it was found to play a fundamental role in the modeling of a considerable number of phenomena; in particular the modeling of memory-dependent and complex media. Fractional calculus generalizes integrals and derivatives to non-integer orders and has emerged as an important tool for the study of dynamical systems where classical methods reveal strong limitations. This book is addressed to a wide audience of researchers working with fractional dynamics, including mathematicians, engineers, biologists, and physicists. This timely publication may also be suitable for a graduate level seminar for students studying differential equations.

“Topics in Fractional Differential Equations” is devoted to the existence and uniqueness of solutions for various classes of Darboux problems for hyperbolic differential equations or inclusions involving the Caputo fractional derivative. In this book, problems are studied using the fixed point approach, the method of upper and lower solution, and the Kuratowski measure of noncompactness. An historical introduction to fractional calculus will be of general interest to a wide range of researchers. Chapter 1 contains some preliminary background results. Chapter 2 is devoted to fractional order partial functional differential equations. Chapter 3 is concerned with functional partial differential inclusions, while in Chapter 4, functional impulsive partial hyperbolic differential equations are considered. Chapter 5 is concerned with impulsive partial hyperbolic functional differential inclusions. Implicit partial hyperbolic differential equations are considered in Chapter 6, and finally in Chapter 7, Riemann-Liouville fractional order integral equations are considered. Each chapter concludes with a section devoted to notes and bibliographical remarks. The work is self-contained but also contains questions and directions for further research.

The name “random walk” for a problem of a displacement of a point in a sequence of independent random steps was coined by Karl Pearson in 1905 in a question posed to readers of “Nature”. The same year, a similar problem was formulated by Albert Einstein in one of his Annus Mirabilis works. Even earlier such a problem was posed by Louis Bachelier in his thesis devoted to the theory of financial speculations in 1900. Nowadays the theory of random walks has proved useful in physics and chemistry (diffusion, reactions, mixing in flows), economics, biology (from animal spread to motion of subcellular structures) and in many other disciplines. The random walk approach serves not only as a model of simple diffusion but of many complex sub- and super-diffusive transport processes as well. This book discusses the main variants of random walks and gives the most important mathematical tools for their theoretical description.

The restaurant at the end of the random walk: recent developments in the description of anomalous transport by fractional dynamics

Ralf Metzler and Joseph Klafter

Publication information: Ralf Metzler and Joseph Klafter. The restaurant at the end of the random walk: recent developments in the description of anomalous transport by fractional dynamics. J. Phys. A: Math. Gen. 2004, 37 R161. doi:10.1088/0305-4470/37/31/R01

http://iopscience.iop.org/0305-4470/37/31/R01

Abstract
Fractional dynamics has experienced a firm upswing during the past few years, having been forged into a mature framework in the theory of stochastic processes. A large number of research papers developing fractional dynamics further, or applying it to various systems have appeared since our first review article on the fractional Fokker–Planck equation (Metzler R and Klafter J 2000a, Phys. Rep. 339 1–77). It therefore appears timely to put these new works in a cohesive perspective. In this review we cover both the theoretical modelling of sub- and superdiffusive processes, placing emphasis on superdiffusion, and the discussion of applications such as the correct formulation of boundary value problems to obtain the first passage time density function. We also discuss extensively the occurrence of anomalous dynamics in various fields ranging from nanoscale over biological to geophysical and environmental systems.

Random walk approximation of fractional-order multiscaling anomalous diffusion

Yong Zhang, David A. Benson, Mark M. Meerschaert, Eric M. LaBolle, Hans-Peter Scheffler

Publication information: Yong Zhang, David A. Benson, Mark M. Meerschaert, Eric M. LaBolle, Hans-Peter Scheffler. Random walk approximation of fractional-order multiscaling anomalous diffusion, Phys. Rev. E 74, 026706 (2006) [10 pages]

http://pre.aps.org/abstract/PRE/v74/i2/e026706

Abstract
Random walks are developed to approximate the solutions of multiscaling, fractional-order, anomalous diffusion equations. The essential elements of the diffusion are described by the matrix-order scaling indexes and the mixing measure, which describes the diffusion coefficient in every direction. Two forms of the governing equation (also called the multiscaling fractional diffusion equation), based on fractional flux and fractional divergence, are considered, where the diffusion coefficient and the drift vary in space. The particle-tracking algorithm is also extended to approximate anomalous diffusion with a streamline-dependent mixing measure, using a streamline-projection technique. In this and other general cases, the random walk method is the only known way to solve the nonhomogeneous equations. Five numerical examples demonstrate the flexibility, simplicity, and efficiency of the random walk method.
