Feasibility of Output-Only Modal Identification Using Wireless Sensor Network: A Quantitative Field Experimental Study

Decentralized Output-only Modal Identification Techniques for Wireless Monitoring Systems

Sensor network technology entails the deployment of small, low-power sensor nodes that can communicate with one another. Since sensor networks can be used to monitor the condition of many types of architectural spaces, the technology has recently received significant academic and industrial attention. Amongst the potential applications, structural monitoring of large-scale civil structures is o...

Output-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data

The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...

Output-only modal parameter identification of civil engineering structures

The ambient vibration measurement is a kind of output data-only dynamic testing where the traffics and winds are used as agents responsible for natural or environmental excitation. Therefore an experimental modal analysis procedure for ambient vibration testing will need to base itself on output-only data. The modal analysis involving output-only measurements present a challenge that requires t...

Topology Control in Wireless Sensor Network using Fuzzy Logic

Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, the use oftopology control is required to decrease power consumption and increase network acce...
