The main objective of this paper is to present the application of the minimal controller synthesis algorithm on a satellite attitude control system. This algorithm is an extension to the model reference adaptive control algorithm. It has a simple structure with relatively few computational requirements per time step. The description of attitude kinematics of the rotational motion of rigid body satellite...
Invisible watermarking methods have been applied in frequency domains, trying to embed a small image inside a large original image. The original bitmap image will be converted into frequency domain to obtain the discrete cosine transform (DCT) matrices from its blocks. The bits of the logo image are embedded in random color components of the original image, as well as in random positions in each selected...
