The objective of this thesis is to design an All Digital Phase Locked Loop (ADPLL) to align the higher frequency signal at the output of the PLL with its input. This work presents a low power All Digital Phase Locked Loop (ADPLL) for the video applications. The ADPLL has wide range of operating input frequency from 10 kHz to 150 kHz....

The concept of cooperative communication in cognitive radio CR networks is used to economize the over utilization of spectrum in accommodating a rising demand of higher data rates for wireless services. The CR typically consists of the Primary User (PU), the Cognitive Relays (CRs), the Cognitive Controller (CC) and the Secondary User (SU)....

Solid state fermentation has been advocated for its advantages over the submerged fermentation in select situations. The technology is of special application where microbial exoenzymes, the cells and their products are to be retained within the produce....

Within the biosphere every object is influenced by microbial activities. A very unfamiliar case is represented by the microorganisms involved in the process of corrosion of different metals and their alloys. Many workers have reported bacteria responsible for initiating, accelariting and promoting the process of corrosion....
