Abstract.
Thermoelectric energy harvesting is emerging as a promising alternative energy source to drive wireless sensors in mechanical, civil, and aerospace engineering systems.
Introduction Wireless sensors, engineered as miniaturized, low-cost embedded devices with integrated sensing, processing, and radio communication capabilities, have recently gained substantial attention for use in different monitoring applications [1].
In recent years, the incompressible fluid flow and heat transfer over rotating bodies have many industrial and engineering applications such as gas turbine engines and electronic devices having rotary parts and have been studied in many industrial, geothermal, geophysical, technological and engineering fields [8].

Abstract.
Combined with the engineering example for the application ,shows that the prediction model has good effect in multi modality support vector, a high degree of agreement with the monitoring values, indicating that this method has a promotional value.
Based on a high test time of settlement of composite foundation engineering examples of sequence data, modal signal processing experience of the application of adaptive decomposition (Empirical Mode Decomposition, EMD) algorithm, to obtain the internal characteristics of the same set of observed data, the characteristics of information SVM forecast, finally establish prediction model of multi modal settlement based on the combination of EMD and SVM foundation.
If there is no great difference between the pre-conditions and post-conditions , Through the engineering settlement observation data of these characteristic modes of will can well describe the modal rules later under specified conditions.

Reliability analysis is an emerging field of structural engineering which is very significant in structures of great importance like arch dams, large concrete dams etc.
A comprehensive review of studies on fuzzy reliability was presented by Ross Reinhard Viert (2008) [6], who combined fuzzy set theory and reliability research to evaluate the risk in civil engineers.
