Electroencephalography (EEG) has potential medical, military and industrial applications. To date, no method is said to be a standardized EEG estimator. The aim of this study is to realize QR decomposition based recursive least square estimator for EEG feature extraction. The features are modeled as adaptive autoregressive model. Linear discriminant analysis is performed to classify the extracted features for a dual class experiment. For validation, right- and left-hand movement imaginations based EEG experiments are conducted. Further validation, carried out by a comparative study with other adaptive (least mean squares and recursive least squares) algorithms, demonstrates the effectiveness of the proposed method.

Greatly unexplored vastness of the ocean attracts human beings to discover knowledge in deep water. Underwater environment is a big challenge for human beings because of changeable and unknown conditions. A highly precise, real time and continuous monitoring system is extremely important for underwater aquatic surveillance, river and sea pollution discovery, oceanographic data compilation and commercial exploitation of the aquatic environment. Underwater Wireless Sensor Networks (UWSNs) with acoustic channel have better performance than radio and optics in underwater environment for interactive communication. However, current techniques suffer from several limitations due to unique challenges of underwater environment such as propagation delay, absorption loss and low bandwidth. Reliability is a major requirement in developing a communication technique that provides effective communication in terms of timeliness of data, better utilization of the channel and bandwidth. In this paper, we propose a naturally adaptive communication technique with an availability of bandwidth to transfer variable length packets. The packet size is determined by parameters including temperature, pressure, salinity and available bandwidth of acoustic channel.

This paper highlights the digital control problems and issues during the controller design and suggests the solutions to resolve them. For this purpose, digital controller designed on the basis of digital redesign or emulation technique is applied to a buck converter working in continuous conduction mode. Nonlinearities due to the ADC and DAC quantizers, loop-delay, etc. are introduced into the control loop and their adverse effects on performance are interrogated. The nonlinearities are suppressed by retuning the digital controller. The order of the controller may increase and require more resources for its implementation. The quantizers' nonlinearities add quantization noise into the loop and may cause offsets and limit cycle oscillations (LCOs). The overall phase margin gets reduced due to the delay thus keeping the bandwidth limited and leading the system towards instability. The well-tuned loop remains asymptotically stable if the nonlinearities are neglected. MATLAB/Simulink environment is used to address all the issues.

Mobile communication systems based on 3G and 4G technologies use adaptive antenna arrays to increase their coverage and channel capacity. Adaptive antenna arrays involve direction finding and beamforming algorithms to localize and track both signals i.e. users and interferers. This paper presents simulation and analysis of three high resolution direction finding algorithms namely MUSIC, Root-MUSIC and ESPRIT. These algorithms provide an estimate about the number of incoming signal sources and their angles of arrival on an antenna array. Simulation results have been used to evaluate the performance of these algorithms by varying the antenna array parameters such as number of mobile users, number of antenna elements, time samples acquired and signal-to-noise ratio.

Multi-document summarization aims to produce a compressed version of numerous online text documents and preserves the salient information. A particular challenge for multi-document summarization is that there is an inevitable overlap in the information stored in different documents. Thus, effective summarization methods that merge similar information across the documents are desirable. This paper introduces a clustered genetic semantic graph approach for multi-document abstractive summarization. The semantic graph from the document set is constructed in such a way that the graph vertices represent the predicate argument structures (PASs), extracted automatically by employing semantic role labeling (SRL); and the edges of graph correspond to semantic similarity weight determined from PAS-to-PAS semantic similarity, and PAS-to-document relationship. The PAS-to-document relationship is expressed by different features, weighted and optimized by genetic algorithm. The salient graph nodes (PASs) are ranked based on modified weighted graph based ranking algorithm. The clustering algorithm is performed to eliminate redundancy in such a way that representative PAS with the highest salience score from each cluster is chosen, and fed to language generation to generate summary sentences. Experiment of this study is performed using DUC-2002, a standard corpus for text summarization. Experimental results indicate that the proposed approach outperforms other summarization systems.

The tremendously increasing number of WSN applications calls for the efficient management of energy which is often achieved through developing the energy efficient MAC protocols. Polling based MAC protocols were introduced to achieve energy efficiency by making the nodes independently waking up and checking the channel activity. Dynamic polling is relatively a recent technique deployed in a number of asynchronous protocols; this type of polling ensures that nodes preserve the energy which can otherwise be lost in the activities of over hearing, idle listening, congestion and synchronization. This paper surveyed the recent WSN MAC protocols based on dynamic polling mechanism. In order to achieve better energy and delay performance, the suggestion for studying and selecting the polling interval distribution for MAC protocols has been made in the light of analysis.

High Definition (HD) videos are the most widely used in HD television and mobile phones now a days for transmission and storage. Due to large data size, HD videos require efficient and robust video coding mechanism to enable real-time encoding. Numerous Motion Estimation (ME) algorithms are proposed to reduce the computational complexity of the coding process. In this paper, we present the performance analysis of some famous Block Matching ME Algorithms (BMAs) for HD videos. Different performance measuring parameters are used to evaluate the performance of BMAs, like Peak Signal to Noise Ratio (PSNR), ME time, Mean Square Error (MSE). The simulation results show that the Adaptive Rood Pattern Search (ARPS) ME algorithm outperforms in term of MSE, PSNR and number of search points, for HD (720p) videos, over various search parameters. ARPS, Diamond Search (DS) and Flatted Hexagon Search (FHS) ME algorithms improve the PSNR from 32dB to 48dB for some video sequences, by increasing search range, whereas the number of search points also increased with the same parameter that causes to increased ME time and computational complexity.

A stacked-dielectric resonator antenna (S-DRA) with frequency reconfigurability and radiation pattern diversity is presented for DVB-H application. Two metallic patches are used that can be connected by RF switches to extend the ground plane. By extending the ground plane, pattern diversity and reconfigurability is achieved. This antenna offers reconfigurability from 0.47 GHz to 0.89 GHz for return loss below -10 dB. Performance in terms of return loss, current distributions, peak gain, radiation pattern and total efficiency of the designed antenna is presented that covers UHF band IV and V, respectively.

In this paper a robust Model Predictive Controller (MPC) is designed for direct drive electro-hydraulic position servo system in presence of unknown dynamics and uncertain nonlinearities. While considering the nonlinearity of dead zone and also the saturation in direct drive electro-hydraulic servo system, the PID controller suffers from problem of poor robustness and also adaptability. In MPC control technique, model of the position servo system is used in order to predict the future evaluation of the plant for optimizing the control signal. The proposed controller is tested for different scenarios of unmeasured and measured disturbances to the system. The results presented show enhancement in the position tracking performance with the rejection of both measured disturbances and unmeasured Gaussian disturbances. The performance of MPC is also compared with PID controller. The control accuracy, robustness capability and response speed of the position servo system have been significantly improved with MPC controller.
