App Based – Comparative Study Of PID And FOPID Controllers[ ]


PID controllers are being widely used in the industry due to their well grounded established theory, ease of retuning and simplicity. A controller is a device that is used to regulate the behavior or response of a process so as to get desired response. Designing a PID controller to meet gain and phase margin specification is a well known design technique but introduction of fractional order calculus in PID controllers gave a start to the new era with addition of two more parameters to tune for efficient system response. This has been compared with the help of an app based on Matlab Script for the designed models of PID and FOPID controllers with DC motor as a plant of the system.

GLOBALISATION AS A THREAT TO CULTURAL DIVERSITY IN AFRICA: THE CAMEROON EXPERIENCE[ ]


The effect of globalization on various aspects of the life of third world countries has always been controversial in nature. The imminent phenomenon of globalization has been mainly explored in academia through the lens of economics and politics. Little attention has been given to the relationship between this phenomenon and culture in Cameroon in particular and Africa in general, and yet the yield of this relationship could be tremendous in Cameroon where people, especially young people no longer take an interest to own culture. This paper thus examines how or the extent to which globalization poses as a threat to cultural diversity in Cameroon.
