Having not been examined the busbar sufficiently until now as a communication channel in the narrowband PLC communication increases the importance of this issue twice as much. Therefore, as a PLC communication channel, the channel characteristics of the busbar should be determined. The aim of this study is to investigate the characteristics of the busbar for the narrowband PLC applications. This study will be a step to estimate the necessary channel characteristics to correctly reveal and design the communication systems. For this purpose, the circuit parameters of the aluminum conductor series busbar system (S-parameters) are modelled and simulated with currently available software and measured experimentally. Then, narrowband propagation properties of a 630 A current level busbar from S-parameters are extracted to elucidate the PLC opportunities.

A communication system exploiting the regime of generalized chaotic synchronization between the transmitter and receiver is proposed that has only one self-oscillating response system in the receiver. The efficiency of the proposed scheme is shown for the case where the transmitter and receiver are constructed using time-delayed feedback oscillators. The communication scheme is studied numerically and realized in the physical experiment. It is shown that the proposed scheme possesses high tolerance to noise in the communication channel.

This article presents new square wave and PWM signal generators based on CC-CDTRA (Current controlled current differencing transresistance amplifier). The oscillation frequency can be adjusted by input bias current of the CC-CDTRA. In addition, for PWM signal generator, the duty cycle of the output signal is 50% which is agree with typical applications. Furthermore, the duty cycle is linear dependent on the modulation signal. The PSpice simulation results confirm that the proposed circuit performs power consumption of 3.61mW at ±3V power supplies. Performances of the proposed circuit are confirmed, they are in accordant to theoretical explanations.

The paper describes an experiment using the Gaussian mixture models (GMM) for automatic classification of the speaker age and gender. The developed two-level architecture is compared with the standard one-level GMM classifier in more detail analysing the influence of different number of mixtures and different types of speech features used for GMM gender/age classification and also regarding the computational complexity in dependence on the applied number of used mixtures. Finally, the GMM classification accuracy is compared with the evaluation using the conventional listening test method. The obtained summary results of 92.3 % mean age classification accuracy for the proposed two-level architecture are better than those for the one-level standard architecture (78.7 %) as well as for evaluation by the listening test method (74.6 %). However, the computation complexity in two levels is about twice higher than in one level, either for GMM model creation or for classification phases.

In the article we present a new method of feature extraction from EEG signal for SSVEP recognition, called a simplified Matching Pursuit (sMP). The method has been tested on SSVEP for stimulation frequencies close to each other - 5, 6, 7, 8Hz. Its effectiveness has been verified and compared with commonly used for this purpose FFT method. sMP enables effective detection of SSVEP with an accuracy of 98%.

Future wireless networks will have to provide seamless connectivity anytime and everywhere while fulfilling conditions concerning sustainable bit rates and maximum delays. Next generation wireless networks will provide communication services not only to persons but also to machines which will have as consequence a significant increase of the number of terminals connected and involved in the communication process. In order to solve these wireless communication issues the design of new radio interfaces is considered as well as the joint usage of the transmission resources available in heterogeneous wireless networks which cover the same geographical area. This paper proposes the architecture and some design principles and implementation details of an advanced mobile router platform with combined vertical handover and load balancing capabilities in heterogeneous wireless networks. The architecture of the testbed used for functionality testing and performance evaluation of the mobile router is also presented together with some relevant test results.

In this paper voltage-mode fractional-order low- and high-pass filters using universal voltage conveyors are presented. The assumed order of the filters is (1 + α), where 0 <; α <; 1. The proposed structures use the continued fraction expansion approach and hence the fractional-order transfer functions of the filters are approximated by integer-order functions. The proposed structures are easily cascadable since their output impedance is zero in theory. The performance of the filters has been verified by Spice simulations that show the proper behaviour of the proposed structures.

Electrooculography (EOG) enables users to use specific eye movements as inputs for various applications, without using their fingers. However, online classification of such signals often requires long or sophisticated calibration procedures and multiple electrodes, which makes the resulting systems not practical for everyday use. To this end, a single-channel bio-potential recording system was used to develop a Personal Identification Number (PIN) input application, based on a simple and short unsupervised calibration method. The average accuracy achieved from five healthy subjects was 98.24%. The high accuracy, combined with the use of single-channel recording with convenient electrode placement resulted in a system that could be embedded in a reliable wearable human-computer interface (HCI) device.

This paper presents a phonetic analysis and recognition of classical and recited Arabic speech phonemes, mainly vowels, using hidden Markov model (HMM) classifiers. For this purpose, a new classical Arabic speech corpus was planned and designed. The corpus is based on recitations extracted from The Holy Quran of specific scripts. For modeling long vowels, we carry out extensive experiments that aim at finding the best way to capture the vowel durations that are semantically relevant in the Arabic language. Our approach consists of adapting the HMM topology to the type of vowels. This method can be applied to other Semitic languages or for the modeling of the geminated phonemes. The proposed method outperforms the baselines systems by achieving an overall correct rate of 87.60% with no specified language model.

This paper proposes an image-adaptive steganalysis algorithm for LSB-Matching steganography. In the proposed method, the content features of the input image are analyzed in order to obtain a classification composed by plain and non-plain regions. In this context, only the plain regions of the input image are considered to determine if the image contains or not hidden information. The experimental results show that the proposed steganalysis algorithm outperforms the conventional LSB-Matching steganalysis algorithms in terms of detection performance and the same time minimizes the inter-database error. The results are shown through the ROC curves that illustrate a better performance of the proposed algorithm.
