A new view of nonlinear water waves: the Hilbert spectrum [PDF]

open access: yesAnnual Review of Fluid Mechanics, 1999
We survey the newly developed Hilbert spectral analysis method and its applications to Stokes waves, nonlinear wave evolution processes, the spectral form of the random wave field, and turbulence.

(k,ψ)-Hilfer Nonlocal Integro-Multi-Point Boundary Value Problems for Fractional Differential Equations and Inclusions

open access: yesMathematics, 2022
In this paper, we establish existence and uniqueness results for single-valued as well as multi-valued (k,ψ)-Hilfer boundary value problems of order in (1,2], subject to nonlocal integro-multi-point boundary conditions.

Fractional Integral Inequalities via Hadamard’s Fractional Integral

open access: yesAbstract and Applied Analysis, 2014
We establish new fractional integral inequalities, via Hadamard’s fractional integral. Several new integral inequalities are obtained, including a Grüss type Hadamard fractional integral inequality, by using Young and weighted AM-GM inequalities.

Boundary Value Problems for Fractional Differential Equations with Fractional Multiterm Integral Conditions

open access: yesJournal of Applied Mathematics, 2014
We discuss the existence and uniqueness of solutions for boundary value problems involving multiterm fractional integral boundary conditions. Our study relies on standard fixed point theorems. Illustrative examples are also presented.

Existence Results for Sequential Riemann–Liouville and Caputo Fractional Differential Inclusions with Generalized Fractional Integral Conditions

open access: yesMathematics, 2020
Under different criteria, we prove the existence of solutions for sequential fractional differential inclusions containing Riemann–Liouville and Caputo type derivatives and supplemented with generalized fractional integral boundary conditions.

Vibration-based damage detection in plates by using time series analysis [PDF]

open access: yes, 2008
This paper deals with the problem for vibration health monitoring (VHM) in structures with nonlinear dynamic behaviour. It aims to introduce two viable VHM methods that use large amplitude vibrations and are based on nonlinear time series analysis.

Complex Network Analysis and Nonlinear Dynamics [PDF]

open access: yes, 2016
This chapter aims at reviewing complex network and nonlinear dynamical models and methods that were either developed for or applied to socioeconomic issues, and pertinent to the theme of New Economic Geography. After an introduction to the foundations of the field of complex networks, the present summary introduces some applications of complex networks

Henry-Gronwall Integral Inequalities with “Maxima” and Their Applications to Fractional Differential Equations

open access: yesAbstract and Applied Analysis, 2014
Some new weakly singular Henry-Gronwall type integral inequalities with “maxima” are established in this paper. Applications to Caputo fractional differential equations with “maxima” are also presented.
