This generated harmonics due to nonlinear load affects the voltage waveform. Most power systems can accommodate a certain level of harmonic but we have problems when harmonics become an indicative component of overall load. As these higher frequency harmonics flow through the power system affects the communication, overheating and hardware damage such as overheating of electrical equipment, cables,...

Now the rapidly increase in the computation power, CR creates an increasing demand for new emerging applications, which require more advanced methodologies. The problem of character segmentation and its recognition in India...
In modern communication systems, OFDM technique is extensively useful to reduce the bandwidth and its enhancement ability of the data rate. In this paper, we deal with generalize model of OFDM system in wireless communication. And we represent communication channel which is sparse in nature. For such channel condition, to reconstruct the signal, sparse channel estimation methods are used. Hence we...
In this paper, a slotted rook shaped novel wide band microstrip patch antenna suitable to be employed for C-Band satellite downlink, Radio Altimeter, IMT, WiMAX applications has been proposed. The proposed antenna is resonant at 4.3 GHz with an impedance bandwidth of 1.419 GHz (3.181 GHz to 4.6 GHz) and a return loss of −53.94dB. The Teflon is used as substrate for designing the proposed antenna having...
This paper consists of a comparative analysis of full reference image quality measures. The quality evaluation model of Peak signal to noise ratio (PSNR), Structural Similarity Index (SSIM) as well as Visual Information Fidelity (VIF) has been discussed.

The paper emphasizes on the design and performance analysis of high directivity FR4 substrate slotted defected ground microstrip patch antenna for X-Band applications. The antenna has been fed by microstrip feedline via impedance transformer to match the impedance of proposed antenna with the 50Ω impedance of co-axial connector used for feeding power to the antenna. The propounded antenna has been...
Database management system is not enough for new high-tech attack, so Database Intrusion Detection System is required as additional security layer. Over the last few years, many database intrusion detection systems are developed using anomaly method like mining data dependencies among data items, access pattern etc. In this paper we have used signature based approach, which is defined on role hierarchy...
In this paper, a swarm intelligence based neural network named as Particle Swarm Optimization — Functional Link Multi Layer Perceptron (PSO-FLMLP) is proposed for suppression of Rician noise from Magnetic Resonance Imaging (MRI) images. The performance of PSO-FLMLP is also compared with three other competitive networks such as Multi Layer Perceptron (MLP), Least Mean Square based Functional Link Artificial...
Everyday huge amount of information are transferred from one network to another, the information may be exposed to attacks. The information and information system should be protected from unauthorized users. To provide and maintain the Confidentiality and Integrity of the information is a very tedious job so Intrusion Detection plays a very important role. Although various methods are used to protect...
