The paper presents a procedure for fault feeder detection in distribution power systems, based on the use of the amplitude-time and argument-time by S-transform of the zero-module bus voltage and two phase currents transients associated with the fault-originated traveling waves. The analysis carried out shows that the argument of currents have difference 180° between fault feeder and sound feeders...
Supply chain stability is a main feature of effective operation. In order to analyze the stability problem of supply chain system under the shock load, Bessel function has been used to simulate the stress wave propagation in supply chain system under the external shock load. The momentum properties of system's wave function are given by the Fourier transform, and it has been shown by superposition...
In tasks related to the analysis and recognition of pathological speech it is often more important to provide the respective person (e.g. physician) with guidelines for a deformation degree assessment of speech signal than to achieve a very accurate automated recognition. By ear it is easy to judge whether the speech is regular or deformed, but any attempt of a deformation degree evaluation is not...
A brain-computer interface (BCI) is a communication system that translates brain-activity into commands for a computer or other devices. In this paper, we used a new method: relative wavelet energy (RWE) for feature selection in BCI design. Linear discriminant analysis (LDA) and support vector machine (SVM) were utilized to classify the pattern of left and right hand movement imagery. Its performance...
