An attractive feature of FRP structures is that Fiber-Optic Sensors (FOS) can be naturally embedded during the production process and provide important structural information immediately after construction. Thus, FOS became very useful also for Vibration-Based Monitoring (VBM) applications. In VBM, damage identified by detecting damage-related changes in modal characteristics a structure, such ...

The importance of energy crisis and global warming necessitates presenting strategies in order to decrease the amount of emissions as well as fuel consumption in large and complex industries such as refineries and petrochemical industries. Generally, refinery steam networks are regarded as units which consume fuel enormously. In this paper, the steam network of Tehran Oil Refinery is considered...

We consider optimization problems related to the prevention of large-scale cascading blackouts in power transmission networks subject to multiple scenarios of externally caused damage. We present computation with networks with up to 600 nodes and 827 edges, and many thousands of damage scenarios. 1 Partially funded by NSF award 0521741.

Nowadays, the service industries play an essential role in the economic development of countries, and among the various fields of insurance, life insurance is of particular importance because it covers its cover directly to humans. Increased competition in the insurance industry has led managers to seek marketing strategies that, in addition to increasing insurance sales, reduce costs and gain ...

Abstract In the framework of direct Structural Health Monitoring approaches, this paper presents a low frequency range analysis performed on steel truss bridge designed in 1946 and built up Northern Italy. The is instrumented with permanent structural health monitoring system, that guarantees continuous flux data information from heterogeneous set sensors. analysis, static quasistatic responses...

In this paper, a drive-by damage detection methodology for high-speed railway (HSR) bridges is addressed, to appraise the application of Mel-frequency cepstral coefficients (MFCC) extract Damage Index (DI). A finite element (FEM) 2D VTBI model that incorporates train, ballasted track and bridge behavior presented. The formulation includes irregularities damaged condition induced in specified st...
