Distributed computing strategy for structural health monitoring

Networked Computing for Structural Health Monitoring

This paper studies the problem of distributed computation over a wireless network of resource constrained sensor nodes. In particular, we focus our attention on sensor networks used for structural health monitoring. Within this context, the heaviest computation is to determine the singular value decomposition (SVD) to extract mode shapes (eigenvectors) of a structure. Compared to collecting raw...

Structural Health Monitoring Using Evolutionary Computing

In this system, the problem of damage detection is formulated as an inverse problem. Solving the inverse problem, it is possible to obtain the damage location and degree. Evolutionary computing is applied to solve the damage problem. PSO-GA, based on Particle Swarm Optimization (PSO) and Genetic Algorithms (GA), is used to solve the problem. Furthermore, Improved PSO-GA is proposed here, which ...

Distributed Processing in Wireless Sensor Networks for Structural Health Monitoring

Hardware-accelerated wireless sensor network for distributed Structural Health Monitoring

Civil infrastructure objects are subject to safety-related issues such as increasing loads and extended service live. Costly manual inspections of these structures should therefore be supplemented by automated continuous monitoring. In this work, a hardwareaccelerated wireless sensor network built entirely with energy-efficient embedded components is proposed as the basis for a distributed stru...

A New Strategy for Structural Health Monitoring based on Structural Destroyed Mode and Data Correlation

This paper provides a new strategy for study of Structural Health Monitoring, and discusses establishment of structural safety monitoring system based on the structural destroyed modes and data correlation. Two concepts, structural destroyed mode and data correlation, are given and discussed. The structural destroyed mode refers to the pattern of certain structural state or situation that some ...
