The article considers processing methods and ground of optimal algorithms of signals receive with linear frequency modulation under the power hidden operating conditions. In the article calculating results of noise decorrelation parameter in the optimal t... see more

This paper presents the proposed algorithms for the identification of Short Duration RMS Variations and Long Duration RMS Variations combined with harmonic. The proposed algorithms are Fast Fourier Transform (FFT) and Artificial Neural Network (ANN). The ... see more

The phenomenon of free design discourse raised by companies or printing agencies as a gimmick to face business competition has caused controversy in the graphic design field. Indirectly, this discourse affects the public mindset and becomes a negative sti... see more

The idea that brain activity could be used as a communication channel has rapidly developed. Indeed, Electroencephalography (EEG) is the most common technique to measure the brain activity on the scalp and in real-time. In this study we examine the use of... see more

A compensation technique for rejection of the powerful narrow-band harmonics radiated by power mains is developed for application (in computer-aided system) of detection and registration of the pulse emissions radiated by partial or crown discharges in is... see more

In this paper, small signal analysis of power systems is investigated using Subspace System Identification (SSI) methods. Classical small signal analysis methods for power systems are based on mathematical modeling and linearized model of power system in ... see more

Wind power generation usage is increasing nowadays, especially in the wider sense of distribution areas. Its technical impacts and restrictions are still under study, and in several aspects are kept almost untouched. One of these aspects is the small-sign... see more

In a power system, the analysis of transient signals is the theoretical basis of fault diagnosis and transient protection theory. Shannon wavelet entropy (SWE) and Shannon wavelet packet entropy (SWPE) are powerful mathematics tools for transient signal a... see more

In the traditional studies on small-signal stability probability of a power system with wind farms, the frequency of wind speed was often assumed to obey to some extent a particular probability distribution. The stability probability that is thus obtained... see more
