Abstract: Digital image watermarking is a branch of information hiding in which the ownership information will be hidden in the cover image. Performing digital image watermarking, some important issues such as imperceptibility, robustness, capacity and security should be considered. The strength and weakness of each of these issues depends on the watermark algorithm and also the domain in which the watermark has been hidden. In this research we investigate the role of the different domains used in digital image watermarking and categorize them based on the power of the mentioned issues that each domain potentially and innately offers.

Abstract: PID controllers have been successfully used in versatile applications, especially with the aid of available mature tuning methods such as the Ziegler-Nichols method. Recently, fractional order PID controllers were proposed after a series of researches on fractional calculus. It is intriguing for the flexibility of the adoption of fractional order which is free from the limit of integer order. This paper studied the fractional order PID controller of different fraction order applied in a DC motor system. The simulation results show that the fractional order PID controllers are promising compared to the integer PID controllers.
