Opis:
In the present study, effects of material non-homogeneity and two-parameter elastic foundation on the fundamental frequency parameters of the simply supported beams are examined. Material non-homogeneity is characterized taking into account the parabolic variations of Young's modulus and density along the thickness direction of the beam while the value of Poisson's ratio is assumed to remain constant. The foundation medium is assumed to be linear, homogeneous and isotropic, and it is modeled by the Pasternak model with two parameters for describing the reaction of the elastic foundation on the beam. At first, the equation of the motion including the effects of the material non-homogeneity and two-parameter elastic foundation is provided. Then, the solutions including fundamental frequency parameters versus various non-homogeneity, density and foundation parameters, and length to depth ratio adopting the Timoshenko beam theory as well as the Euler-Bernoulli beam theory are presented. To show the accuracy of the present results, a comparison is carried out and a good agreement is found.

Opis:
The diagnostics of power transformers is a very fast developing branch, due to increasing average age of assets and changes in asset management strategies, nowadays companies introduce asset management based on a real technical condition. One of important methods used for diagnostics of a transformer’s active part is Frequency Response Analysis (FRA). It allows determination of mechanical condition of windings, their displacements, deformations and electric faults, as well as some problems with internal leads and connections, core and bushings. For the aim of windings impedance modeling the RLC models are applied. The idea of lumped parameters models was presented in [6]. The new universal model basing on circuit solution is developed in this paper. Lumped parameters used in calculations are obtained with finite element method and Maxwell package. The examples of models created for simple windings were compared to real measurements.

Conditions of measurement, the analogue-to-digital conversion and the frequency analysis of turned surface irregularities for the purpose of its main components identification are presented in the paper. A range of digital parameters have been defined along with their relation to each other, specifying the ranges in which they should be used in order to measure surface irregularity (Tab.1). The parameter values obtained by digital measurement vary within specific ranges, and hence determine the surface irregularities [1, 2, 3]. For this measurement, it is essential to select proper sampling interval hp and the number of measured data N for the value and character of the irregularities measured [4, 5] (Fig.2). The method of frequency analysis for periodical surface irregularities, with the application of power spectral density and the use of fast Fourier transformation (FFT), has been presented in papers [6, 7]. The required conditions for the method presented in this paper, and the possible matching of frequency to wide-band surface irregularities are presented. The maximum frequency of the given irregularity is determined by the value of the sampling interval. Due to this fact, the sampling interval values should be selected in a way to include the low-frequency range of dominant components of the surface irregularity [8] (Fig.3). To summarise, the resulting frequency range of surface irregularities, with high and low-frequency limitations, has been given. Furthermore, the indication of the suitable selection range to capture significant surface irregularities has been included.

Opis:
Controlling and reducing the radiation emitted by various systems helps the board designer improve systems’ performance. One proposed way to achieve these goals is to use an algorithm to control the radiation applied to systems. According to the executive structure of the algorithm and considering the nature of the existing signals in several components, the separation of the signal components is on the agenda of the algorithm. In fact, the goal is to create an intuitive view of the multi-component signals around the systems that enter the systems from different angles and have a detrimental effect on their performance. Using signal processing methods, we will be able to break down the signal into different components and simulate each component separately. To prevent high computational repetitions and increase simulation time in signal component analysis, by reducing the components, we reduce the number of mesh cells in the software and, using linear approximation, determine the exact position of the radiation signal applied to systems and thus the best linear relationship. The signal entry path is used to apply the rules required for prediction design.

Opis:
Specific requirements are designed and implemented in electronic and telecommunication systems for received signals, especially high-frequency ones, to examine and control the signal radiation. However, as a serious drawback, no special requirements are considered for the transmitted signals from a subsystem. Different industries have always been struggling with electromagnetic interferences affecting their electronic and telecommunication systems and imposing significant costs. It is thus necessary to specifically investigate this problem as every device is continuously exposed to interferences. Signal processing allows for the decomposition of a signal to its different components to simulate each component. Radiation control has its specific complexities in systems, requiring necessary measures from the very beginning of the design. This study attempted to determine the highest radiation from a subsystem by estimating the radiation fields. The study goal was to investigate the level of radiations received and transmitted from the adjacent systems, respectively, and present methods for control and eliminate the existing radiations. The proposed approach employs an algorithm which is based on multi-component signals, defect, and the radiation shield used in the subsystem. The algorithm flowchart focuses on the separation and of signal components and electromagnetic interference reduction. In this algorithm, the detection process is carried out at the bounds of each component, after which the separation process is performed in the vicinity of the different bounds. The proposed method works based on the Fourier transform of impulse functions for signal components decomposition that was employed to develop an algorithm for separation of the components of the signals input to the subsystem.

We have investigated the characteristics of acousto-optic interaction for low-frequency ultrasonic wave in a liquid. Based on the coupling wave equation of acousto-optic interaction, the diffraction light characteristics for normal incidence at small parameter Q have been discussed. The parameter Q with respect to acousto-optic interaction length, ultrasonic frequency, water temperature, and the concentration of sucrose solution have been analyzed, which is an important physical quantity and reflects the degree of mismatch in the acousto-optic interaction. The diffraction efficiencies for different parameters Q, incident angles and phase shifts have been calculated. The results of our work provide theoretical basis for further study of the acousto-optic effect in the liquid.

Opis:
This paper deals with free vibration modes and natural frequencies of a thin visco-elastic, non-homogeneous rectangular plate with clamped ends. First two modes of frequency parameter of vibration are derived on the basis of Rayleigh-Ritz technique. Since the effect of temperature decreases the efficiency and durability of the structure, influence of bi-parabolic temperature variations on vibration of rectangular plate is analyzed. Tapering in rectangular plate is assumed bi-exponentially in x-and y-direction. Effect of non-homogeneity is discussed with exponential variation in density of the plate’s material i.e. visco-elastic material “Duralium” which is an alloy of aluminum. Vibration modes of clamped plate are calculated for various values of thermal gradient, taper parameters and non-homogeneity constant. Results are explained with the help of the graphs.

Opis:
Long transmission lines have to be compensated to enhance the transport of active power. But a wrong design of the compensation may lead to subsynchronous resonances (SSR). For studies often park equivalent circuits are used. The parameters of the models are often determined analytically or by a three-phase short-circuit test. Models with this parameters give good results for frequencies of 50 Hz and 100 Hz resp. 60 Hz and 120 Hz. But SSR occurs at lower frequencies what arises the question of the reliability of the used models. Therefore in this publication a novel method for the determination of Park equivalent circuit parameters is presented. Herein the parameters are determined form time functions of the currents and the electromagnetic moment of the machine calculated by transient finite-element simulations. This parameters are used for network simulations and compared with the finite-element calculations. Compared to the parameters derived by a three-phase short-circuit a significant better accuracy of simulation results can be achieved by the presented method.

Opis:
The aim of this article is to analyze the practice of using of stylistic labels in modern Russian author (writer) dictionaries. It is shown that labels of this type as the main kind of markers of stylistic information characterize, first of all, the explanatory author dictionaries, which have a full corpus. In these dictionaries the set of the stylistic labels represents the selection from the available nomenclature of labels, which is supplemented by new labels. From the functional point of view, such labels are dual – on the one hand, they stylistically structure the author’s lexicon, on the other hand – they are the markers of certain features of his individual style. Among differential authorexplanatory dictionaries, such ones are separated, in which the stylistically painted specific massifs of lexicon are presented. The stylistic unity of such words defines redundancy of labels and therefore the application of special receptions in relation to them (for example, their transfer in a reference part of the dictionary entry) is used. Special attention is given to author registrative dictionaries (to concordances, frequency dictionaries), in which the structure complication is connected with using of stylistic labels. The research is based on the material of Russian author dictionaries published mainly at the beginning of the year 2000.

Opis:
This paper presents a simple DFT-based golden section searching algorithm (DGSSA) for the single tone frequency estimation. Because of truncation and discreteness in signal samples, Fast Fourier Transform (FFT) and Discrete Fourier Transform (DFT) are inevitable to cause the spectrum leakage and fence effect which lead to a low estimation accuracy. This method can improve the estimation accuracy under conditions of a low signal-to-noise ratio (SNR) and a low resolution. This method firstly uses three FFT samples to determine the frequency searching scope, then – besides the frequency – the estimated values of amplitude, phase and dc component are obtained by minimizing the least square (LS) fitting error of three-parameter sine fitting. By setting reasonable stop conditions or the number of iterations, the accurate frequency estimation can be realized. The accuracy of this method, when applied to observed single-tone sinusoid samples corrupted by white Gaussian noise, is investigated by different methods with respect to the unbiased Cramer-Rao Low Bound (CRLB). The simulation results show that the root mean square error (RMSE) of the frequency estimation curve is consistent with the tendency of CRLB as SNR increases, even in the case of a small number of samples. The average RMSE of the frequency estimation is less than 1.5 times the CRLB with SNR = 20 dB and N = 512.
