Fuzzy logic and proportional-integral-derivative (PID) controllers are compared for use in direct current (DC) motors positioning system. A simulation study of the PID position controller for the armature-controlled with fixed field and field-controlled with fixed armature current DC motors is performed. Fuzzy rules and the inferencing mechanism of the(More)
Problem statement: The research presented in this study looks into Mobile Ad-Hoc Networks (MANETs) environment that has varying node densities, called heterogeneous density environment. Such environment can be roughly associated with situations varying from areas struck by disasters to normal city environments. Approach: This study improved the performance(More)
This paper considers a queuing model with batch Poisson input and two heterogeneous servers, where the service times are exponentially distributed. The faster server is always on, but the slower server is only used when the queue length exceeds a certain level. Traditionally, this was done through scheduling policy. In this paper an enhanced algorithm,(More)
