The niche technology and hierarchy genetic algorithmare combined in this paper. Adaptive hierarchy genetic algorithmbased on niche sharing and crowding strategy is presented. Thealgorithm improves genetic algorithm from not only encodingmethod but also operators. Thus it has strong search ability and itis easy to find many global optimums. Simulation results validat-e its efficiency.

A genetic algorithm(GA)-based two-stage fuzzycontroller is proposed for overhead crane. In this controller, twofuzzy sub-controllers are designed to respectively control theswing and displacement. A real-valued GA is used twice indifferent stages to adjust the parameters of the controllers toensure the positioning precision, minimize transporting time andswing angle, and damp swing angle at target position. Simula-tion results demonstrate the effectiveness of this approach.

In this paper, two computationally efficient prefilterstructures are proposed for the design of narrow-band bandpassFIR filters. The prefilters are developed from a multiplicationfree prototype filter. Significant savings in the number ofarithmetic operations can be achieved by applying the prefilter toa modified Interpolated Finite Impulse Response (IFIR) *** examples show that the proposed prefilter structures aremore efficient than the IFIR approach.

In this paper, we consider sliding mode control(SMC) of uncertain systems whose output is contaminatedby external disturbances. The cone-bounded assumption onuncertainties is removed via neural networks. The proposedsliding-mode controller can not only guarantee a uniform ulti-mate boundedness of states of the plant, but also the bound-edness of all other signals in the closed-loop system.

Transfer function analysis is being developed forboth impulse testing and monitoring of power transformersand offers advantages of fault identification and *** on Bergeron's method, a three-phase circuit equivalentto a power transformer is introduced in this paper. Slidinggrounding insulation faults found at different location in thewinding are analyzed and simulated. The results reveal thatchanges in the transfer function help locate the fault andshow the potential contribution to insulation fault monitoringand location.

Because of the large volume of datainvolved in the process and stringent continuityand real-time constraints, a video-on-demand(VOD) system demands novel schemes forscheduling continuous video streams. This paperpresents a simple hybrid admission strategy thatcan increase the number of admitted requestsand reduce the queuing time in a server clustersystem.

A fuzzy control framework, in whichthe measurement model of congestion is appliedto evaluate the congestion degree of the replaceroute and the fuzzy control algorithm is appliedto design the intersection signal setting of thereplace route for eliminating "traffic congestiondiversion", is developed to study networkperformance when the non-recurrent trafficcongestion happens in the network in thepresence of information. The framework isillustrated by detecting the traffic volumes in thereplace route and controlling the traffic volumesat the same time.
