The las.r induced p.as.a dynamics.of grap.ite material are inves.igated by op.ical emis.ion s.ectros.op.. Abla- tion and excitation of the grap.ite material is.p.rformed by us.ng an 1064nm Nd：YAG las.r in different ambient p.es.ures. Characteris.ics.of grap.ite s.ectra as.line intens.ty variations.and s.gnal-to-nois. ratio are p.es.nted with a main focus.on the influence of the ambient p.es.ure on the interaction of las.r-induced grap.ite p.as.a with an ambient environment. Atomic emis.ion lines.are utilized to inves.igate the dynamical behavior of p.as.a, s.ch as.the excitation temp.rature and electron dens.ty, to des.ribe emis.ion differences.under different ambient conditions. The excitation temp.rature and p.as.a electron dens.ty are the p.imary factors.which contribute to the differences.among the atomic carbon emis.ion at different ambient p.es.ures. Reactions.between the p.as.a s.ecies.and ambient gas. and the total molecular number are the main factors.influencing molecular carbon emis. s.on. The influence of las.r energy on the p.as.a interaction with environment is.als. inves.igated to demons.rate the dynamical behavior of carbon s.ecies.s. that it can be utilized to op.imize p.as.a fluctuations.

Grap.ene has.attracted the interes. of chemis.s. p.ys.cis.s. and materials.s.ientis.s.due to its.extraordinary s.ructural, mechanical, and electronic p.op.rties. While p.is.ine grap.ene is.des.rable for ap.lications.that require a high electrical conductivity, many other ap.lications.require modified or functionalized forms.of grap.ene, s.ch as.grap.ene oxide, reduced grap.ene, or other functionalized forms. s.ructurally modifying grap.ene through chemical functionalization reveals.the numerous.p.s.ibilities.for tuning its.s.ructure; s.veral chemical and p.ys.cal functionalization methods.have been exp.ored to imp.ove the s.abilization and modification of grap.ene.

This.p.p.r des.ribes.a s.p.rvis.ry hierarchical fuzzy controller （s.FC） for regulating p.es.ure in a real-time p.lot p.es.ure control s.s.em. The inp.t s.aling factor tuning of a direct exp.rt controller is.made us.ng the error and p.oces. inp.t p.rameters.in a clos.d loop.s.s.em in order to obtain better controller p.rformance for s.t-p.int change and load dis.urbances. This.on-line tuning method reduces.op.rator involvement and enhances.the controller p.rformance to a wide op.rating range. The hierarchical control s.heme cons.s.s.of an intelligent up.er level s.p.rvis.ry fuzzy controller and a lower level direct fuzzy controller. The up.er level controller p.ovides.a mechanis. to the main goal of the s.s.em and the lower level controller delivers.the s.lutions.to a p.rticular s.tuation. The control algorithm for the p.op.s.d s.heme has.been develop.d and tes.ed us.ng an ARM7 microcontroller-bas.d embedded target board for a nonlinear p.es.ure p.oces. having dead time. To demons.rate the effectivenes., the res.lts.of the p.op.s.d hierarchical controller, fuzzy controller and conventional p.op.rtional-integral （p.） controller are analyzed. The res.lts.p.ove that the s.FC p.rformance is.better in terms.of s.ability and robus.nes. than the conventional control methods.

An auto ricks.aw is.a three-wheeled motor vehicle commonly found in As.a, with one front s.eering wheel and two driven wheels.at the back. In automobiles. s.s.ens.on is.us.d to keep.the wheels.p.anted during motion. The trailing arm s.s.ens.on generally found in Indian automobiles.has.its.roll center on the ground. The vehicle＇s.center of gravity is.above the ground, which creates.a moment during vehicle turning known as.the roll moment. When this.roll moment exceeds.a certain limit, the vehicle becomes.uns.able. Roll rate can be exp.es.ed as.degrees.p.r lateral acceleration of the vehicle＇s.s.rung mas., and is.influenced by factors.s.ch as.wheel rate, motion ratio, and s.s.ens.on rate. In order to determine an op.imized three-wheeler s.s.ens.on s.tup. a matrix s.lection method was.us.d, in which every available s.s.ens.on typ. in the market is.rated bas.d on s.lected s.s.ens.on p.rameters.s.ch as.handling, dynamics. and s.mp.icity. From the overall weightage, each s.s.ens.on typ. is.analyzed and the mos. ap.rop.iate is.s.lected. In order to achieve the objective of imp.oving the overall rollover s.ability, certain modifications.have been ap.lied in the s.lected s.s.ens.on des.gn. Generally, if the roll rate of a s.ecific vehicle axle is.high, the p.rcentage of weight trans.er on the axle will als. be high. By imp.oving roll s.iffnes., the amount of roll can be decreas.d, and by op.imizing the motion ratio, the roll moment can be controlled, thereby increas.ng the overall rollover s.ability.
