A Leslie-Gower Hollin. Type-II Predator-Prey Mathematical Model with Disease in.Prey Population.In.orporatin. a Prey Refuge

We formulate an. an.lyze a predator-prey model followed by Leslie-Gower model in.which the prey population.is in.ected by disease. We assume that the disease can.on.y spread over prey population. As a result prey population.has been.classified in.o two categories, n.mely susceptible prey, in.ected prey where as the predator population.remain. free from in.ection. To in.estigate the behaviour of prey population.we in.orporate prey refuge in.this model. sin.e the prey refuge decreases the predation.rate then.it has an.importan. effect in.our predator-prey in.eraction.model. We have discussed the existen.e of various equilibrium poin.s an. local stability an.lysis at those equilibrium poin.s. We in.estigate the Hopf-bifurcation.an.lysis about the in.erior equilibrium poin. by takin. the rate of in.ection.parameter an. the prey refuge parameter as bifurcation.parameters. The n.merical an.lysis is carried out to support the an.lytical results an. to discuss some in.erestin. results that our model exhibits.

An.lysis of Power in.an.Argon.Filled Pulsed Dielectric Barrier Discharge

In.this paper an.argon.filled coaxial dielectric barrier discharge （DBD） has been.studied to un.erstan. the detail of power tran.fer from a un.polar square pulse to plasma durin. discharge. A dielectric barrier discharge based diffuse pulse discharge an. its electrical charac-teristics are in.estigated. A quartz coaxial DBD tube filled at differen. pressures is used in.the experimen.. A un.polar pulse voltage of differen. peak voltages an. frequen.ies has been.applied to the discharge electrodes for the gen.ration.of microdischarges. Two curren. pulses are used for two con.ecutive discharges per applied voltage pulse. The secon. discharge, which occurs at the fallin. flan. of the voltage pulse, is in.uced by the charges stored on.the dielectric barrier durin. the first discharge. It has been.deduced that the power supplied to ign.te the first discharge is partly stored to ign.te the secon. discharge when.the applied voltage decays. This process ul- timately leads to much improved power tran.fer to the plasma. The kn.wledge obtain.d from dyn.mic processes of the DBDs in.the discharge gap explain. quan.itatively the mechan.sm of ign.tion. developmen. an. extin.tion.of the DBDs.
