In the paper is presented a new method for efficient compression of still images, based on the Inverse Difference Pyramid (IDP) decomposition. A special version of the method is developed for the lossless compression of graphics and texts. The method is aimed at secure and flexible transfer of information via Internet. It permits the insertion of multiple digital watermarks in the image phase d...

A few of the well established methods of adaptive signal processing are modified and extended for application to adaptive control. An unknown plant will track an input command signal if the plant is preceded by a controller whose transfer function approximates the inverse of the plant transfer function. An adaptive inverse modeling process can be used to obtain a stable controller, whether the ...

abstract: in this paper, a new population-based search called the bees algorithm (ba) is presented to estimate the time-dependent heat transfer coefficient and the corresponding heat flux at the boundaries of a two-dimensional body subjected to transient heat conduction, using the temperature measurements at discrete nodal locations on the boundaries, where heat flux is specified as the boundar...
