In this paper we introduce a robust image-adaptive data hiding in wavelet domain that hide data in images whileimposing minimal perceptual degradation in original image. As it is well accepted, data embedding in the low and midfrequency parts of an image have better robustness undercompression attacks than high frequency parts. So our methodembeds more data in low frequency coefficients than highfrequency...
The heart is one of the crucial parts of a human being. The heart produces electrical signals and these cycles of electrical signals are called as cardiac cycles. The graphical recording of the cardiac cycle produced by an Electrocardiograph is called as Electro cardio gram (ECG) signal. The Electrocardiogram signal is used to diagnose the irregularity in heart beat. Automatic classification of ECG...
In this paper, a micro-grid consists of clusters of load and distributed generators that operate as a single controllable system is explored by means of computer simulations. The interconnection of distributed generator to the utility through power electronics converters has raised concern about safe operation and protection of the equipment. In this work, a method for power flow control between utility...
