Adaptive Synchronization of Unknown Chaotic Systems Using Mamdani Fuzzy Approach

Autor: Gamal El-Ghazaly

Publikováno v: International Journal of System Dynamics Applications. 1:122-138

The synchronization problem for a general-class of unknown chaotic systems is addressed. Fuzzy systems in Mamdani type are employed to provide an approximate model of the master chaotic system using an adaptive approach. Within this, a number of fuzz

Transfer of material through the microspore exine from the loculus into the cytoplasm

Autor: John R. Rowley, John J. Skvarla, Gamal El-Ghazaly

Publikováno v: Canadian Journal of Botany. 81:1070-1082

Our results and those we review indicate that the exine has a great capacity for modifications that enable nutrients to pass through from the anther loculus to the microspore cytoplasm. Avenues of passage include strands, some of which are viscin thr
