Fractional Derivatives in Interval Analysis

In this paper, interval fractional derivatives are presented. We consider uncertainty in both the order and the argument of the fractional operator. The approach proposed takes advantage of the property of Fourier and Laplace transforms with respect

Treatment of arbitrarily autocorrelated load functions in the scope of parameter identification

Autor: Giulio Cottone, Gerhard Müller, Katrin Runtemund

Publikováno v: Computers & Structures. 126:29-40

Ambient vibration tests are output-only tests based on the structural response recorded under natural excitation, such as wind or traffic loads. In contrast to forced vibration test, they do not require service interruption and expensive devices to e

Stochastic dynamics of nonlinear systems with a fractional power-law nonlinear term: The fractional calculus approach

Autor: Mario Di Paola, Giulio Cottone, Salvatore Butera

Publikováno v: Probabilistic Engineering Mechanics. 26:101-108

Fractional power-law nonlinear drift arises in many applications of engineering interest, as in structures with nonlinear fluid viscous–elastic dampers. The probabilistic characterization of such structures under external Gaussian white noise excit

Stochastic ship roll motion via path integral method

Autor: M. Di Paola, Raouf A. Ibrahim, Antonina Pirrotta, Roberta Santoro, Giulio Cottone

Publikováno v: International Journal of Naval Architecture and Ocean Engineering, Vol 2, Iss 3, Pp 119-126 (2010)

The response of ship roll oscillation under random ice impulsive loads modeled by Poisson arrival process is very important in studying the safety of ships navigation in cold regions. Under both external and parametric random excitations the evolutio

Incipient damage identification through characteristics of the analytical signal response

Autor: Giulio Cottone, Salvatore Salamone, Antonina Pirrotta

Publikováno v: Structural Control and Health Monitoring. 15:1122-1142

The analytical signal is a complex representation of a time domain signal: the real part is the time domain signal itself, while the imaginary part is its Hilbert transform. It has been observed that damage, even at a very low level, yields clearly d

ROC and Cost Curves for SHM Performance Characterization in a Multilevel Damage Classification Framework: Application to Impact Damage in Aircraft Composites Structures

Autor: Ulrike Heckenberger, Luca De Marchi, Giulio Cottone, Alfonso Apicella, Alessandro Marzani

Publikováno v: Structural Health Monitoring 2015.

In this paper, the optimization of maintenance schemes for aircraft structures is treated by a Bayesian updating approach. A built-in structural health monitoring system for multilevel damage detection based on ultrasonic guided waves is considered.

α-stable distributions for better performance of ACO in detecting damage on not well spaced frequency systems

Autor: Antonina Pirrotta, Giulio Cottone, G. Fileccia Scimemi

In this paper, the Ant Colony Optimization (ACO) algorithm is modified through α -stable Levy variables and applied to the identification of incipient damage in structural components. The main feature of the proposed optimization is an improved abil

Nonlinear SDE Excited by External Lévy White Noise Processes

Autor: Giulio Cottone

Publikováno v: Proceedings of the 6th International Conference on Computational Stochastic Mechanics(CSM-6).

A numerical method for approximating the statistics of the solution of nonlinear stochastic systems excited by Gaussian and non-Gaussian external white noises is proposed. The differential equation governing the evolution in time of the characteristi
