Detection of power oscillation and simultaneous faults using Clark transform
Distance relays are widely used to protect transmission lines. Sometimes, in these lines due to the occurrence of the oscillation of the power, the impedance calculated in the distance relay enters into its functional zones and leads to the cutting off of the lines. This issue can cause global power outages. Accordingly, in this paper, a Clark-based method for detecting the oscillation of power...
متن کاملApproximation of the Fourier Transform and the Dual Gabor Window
Many results and problems in Fourier and Gabor analysis are formulated in the continuous variable case, i.e., for functions on R. In contrast, a suitable setting for practical computations is the finite case, dealing with vectors of finite length. We establish fundamental results for the approximation of the continuous case by finite models, namely, the approximation of the Fourier transform an...
متن کاملFabric Defect Detection Using Fourier Transform and Gabor Filters
Nowadays, fabric defect detection is mainly operated based on human inspection. This method is a subjective one, depending on a large number of factors that can influence the human observer, such as the intensity of the lights, the fatigue or the experience of the human observer [1]. This is why, in order to reduce the inspection process costs and to increase the products quality, this process ...

15 صفحه اولIntrusion Detection System Using Discrete Fourier Transform with Window Function
An Intrusion Detection System (IDS) is countermeasureagainst network attack. There are mainly two typesof detections; signature-based and anomaly-based. And thereare two kinds of error; false negative and false positive. Indevelopment of IDS, establishment of a method to reduce suchfalse is a major issue. In this paper, we propose a new anomaly-baseddetection method using Discrete Fourier Trans...
