An Adaptive Segmentation Method Using Fractal Dimension and Wavelet Transform
In analyzing a signal, especially a non-stationary signal, it is often necessary the desired signal to be segmented into small epochs. Segmentation can be performed by splitting the signal at time instances where signal amplitude or frequency change. In this paper, the signal is initially decomposed into signals with different frequency bands using wavelet transform. Then, fractal dimension of ...
متن کاملTheory and Application of Magnetic Flux Leakage Pipeline Detection
Magnetic flux leakage (MFL) detection is one of the most popular methods of pipeline inspection. It is a nondestructive testing technique which uses magnetic sensitive sensors to detect the magnetic leakage field of defects on both the internal and external surfaces of pipelines. This paper introduces the main principles, measurement and processing of MFL data. As the key point of a quantitativ...
متن کاملCalibration curves for on-line leakage detection using radiotracer injection method
One of the most important requirements for industrial pipelines is the leakage detection. In this paper, detection of leak and determination of its amount using radioactive tracer injection method has been simulated by Monte Carlo MCNP code. The detector array included two NaI (Tl) detectors which were located before and after the considered position, measure emitted gamma from radioactive trac...

متن کاملValidation Technique for Pipeline Leakage Localization (VTeLL)
Pipelines are essential parts of the infrastructure of modern society; Leak detection systems (LDS) are used to protect the public and the environment from the effects of pipeline failure as well as bringing down operational costs, LDS do this by alerting when a leak occur and solving the problems of leakages most often involves the application of two or more methods which largely depends on se...
