In this fast developing world of Internet, securing images is a major security concern in storage and communication. Images are prone to tampering, leakage and attacks. Hence, it is very essential to secure images in the fields of medical science, defense and law enforcement. Cryptographic techniques provide secure transmission of confidential images. Among the security requirements, authentication...
This Paper presents a new methodology for the optimal placement of Independent power producer (IPP) based on Locational marginal pricing (LMP) calculation for congestion management in transmission network also with the objective of social welfare maximization. LMP is determined as the Lagrangian multiplier of the power balance equation in Optimal Power Flow (OPF) using PSO. The LMP signal serves as...
Energy efficiency is of prime focus in the design and development of any power conversion system. The value of power factor at the input, affects the efficiency. It is a known fact that most common non-linear loads (such as a rectifier) result in low power factor operation at the ac (alternating current) input due to the presence of harmonics. Low power factor causes power losses, equipment failure,...
In this paper, we suggest a noise robust isolated word speech recognition system which can be applied in various noise environments. In this method, Kalman filter is used to remove the background noise and to enhance the speech signal. The enhanced signal is integrated into the front end of Dynamic Time Warping (DTW) isolated word recognition in order to guarantee high performance and robust recognition...
